Chapter 723 Three Months

In less than half an hour, Xu Xin was already a hundred kilometers away from the World Tree.

Because the World Tree was destroyed, all the helicopters and other tools they had made before were also destroyed.

Therefore, he came here riding Huihui.

"ah--"

Hui Hui hovered over the wreckage of three giant ships of the alien invaders.

Xu Xin looked at the wreckage below and felt a little headache.

Physical headache.

The radiation here is really strong.

Even though Hui Hui was hundreds of meters in the air now, it still made him very uncomfortable.

He looked down.

The three giant ships are all riddled with holes.

What surprised him was that in addition to the obvious twisted cracks on the hull, there were also some regular holes in the hull.

These holes are basically circular holes, and their edges are turned up toward the outside of the giant ship.

This is somewhat intriguing.

It is obvious that these holes are actually broken and pushed open from the inside out.

And, judging from this shape...

Could it be the giant tentacle monster that Yingying mentioned before?

If the hole, which is at least four to five meters in diameter, was opened by the tentacles of the tentacle monster, then how big must the tentacle monster be...

It's a little scary just thinking about it.

Fortunately, the teleportation array is no longer there, and there are no tentacle monsters emerging from the teleportation beam.

Xu Xin looked carefully.

Through these holes, large cracks, and small cracks, he could basically see most of the interior of the giant ship.

The interiors of these giant ships are basically empty.

This is normal. Ji Chaoyang also told him that after their three giant ships crashed, they carried out a very violent nuclear bombing on the wreckage of the giant ships.

At this time, the wreckage of the three giant ships were all located in a huge sinkhole with a depth of hundreds of meters.

Ji Chaoyang's bombing directly turned this place into a "crater."

Under this intensity of bombing, it is basically impossible for the things inside the giant ship to be strong enough to withstand nuclear bombing.

Therefore, it is normal for large parts of the interior to be empty.

However, he still wanted to go down and take a look.

"Hui Hui, do you feel uncomfortable?"

Xu Xin patted Hui Hui and said.

He didn't bring Cocoa this time. He felt that Cocoa's small body might not be able to withstand the radiation here.

"ah--"

Huihui's voice was very energetic, and even the speed of circling accelerated a lot.

It seemed to prove to Xu Xin that there was no problem with it.

Xu Xin nodded.

That means you can persist, as long as there are no major problems. If there are minor problems, Qi Xuefei's medicine can restore him and Hui Hui.

"Let's go down and take a look at the wreckage of the giant ship first."

The giant ship he pointed at was the most complete of the three giant ship wrecks. At least there was still a complete giant ship as a whole.

If there is a tank inside a giant ship that can move autonomously, this one is the most likely.

"ah--!"

Hui Hui immediately dived and rushed towards the wreckage of the giant ship that Xu Xin was pointing at.

Then it spun in the air and drilled directly into a large crack in the hull of the giant ship.

"Hello--!"

This almost threw Xu Xin off, but fortunately he held on tightly.

The acceleration of Huihui's dive is much faster than that of free fall.

This is much more exciting than bungee jumping...

Hui Hui fell to the ground and leaned over.

Xu Xin calmed down her heartbeat.

He didn't jump off Hui Hui's body, but looked around.

Empty.

This is just... too empty.

Inside, there's really nothing left.

All that was left of the entire giant ship was a huge empty shell.

Under normal circumstances, the interior of a giant ship should be layered.

But the internal layering is naturally not made of materials as strong as the hull of a giant ship. Under the violent nuclear explosion, it may be directly exploded into molecules.

Sunlight shines in through the holes in the huge ship's hull, and in the soil exposed by the holes in the hull's ground, some... strangely colored, seemingly colorful grass grows.

“There’s grass growing here?”

It was obviously just bombed not long ago?

But think about it, this is already a place where vegetation growth is affected by the World Tree.

The vitality of the World Tree cannot be underestimated. On the soil affected by the World Tree, no matter how bombed it is, it can recover in a short time.

Just like now, small green seedlings are sprouting everywhere next to Crystal City. I am afraid that within a few days, this jungle will be restored again.

Xu Xin looked around again.

Except for these weird grasses that have grown in a very harsh environment, nothing useful can be seen in the entire giant ship.

"Huihui, over there."

Xu Xin pointed to the grass about two hundred meters away from him.

That piece of grass happened to be illuminated by the sunlight exposed through the hole above the giant ship's hull, so it grew very well.

Moreover, the colorful colors look very beautiful under the sunlight.

Moreover, under his identification ability, the grass actually emitted a purple grade light.

"ah--"

Hui Hui flew over twice.

Xu Xin turned over, squatted down, and stirred the grass.

[Radiation Grass (Purple): A grass that grows in strong radiation and is extremely tenacious. It does not contain radioactive radiation, is highly toxic, and is inedible, but it has the effect of absorbing and reducing surrounding radiation. After being pulled out, the ability to absorb radiation will continue to exist for 2 hours. 】

Oops!

Grass that reduces surrounding radiation?

No wonder he stood on the edge of the grass and felt that the pain in his head had eased.

Moreover, after being pulled out, it still has the ability to absorb radiation for two hours.

Isn't this exactly what they need now!

They want to go back to the alien invaders' lair again to check the situation there.

The radiation over there right now is super strong.

Li Wenxi has already asked them to make some radiation-proof suits, but the radiation over there is caused by the main guns of the alien invaders' giant ships, and even the radiation-proof suits may not be able to protect them much.

Having this kind of grass can also reduce the intensity of radiation.

"Dig some."

He dug up some radiata grass a little, mainly for grass seeds.

However, the ability of this grass to produce grass seeds is really too low. It took a few minutes to dig out a whole patch, but only three grass seeds were produced.

[Radata Grass Seeds (Purple): It only takes three minutes to grow into a patch of Radiation Grass. 】

Um.

Enough, not bad.

This thing can be planted directly in the bracelet and picked when needed.

He gathered the grass seeds and climbed onto his gray back.

"Let's go to the next huge ship wreckage."

The wreckage of the second giant ship is nothing to look at.

Because this giant ship is several times more damaged than the previous one.

It broke directly into two big pieces!

The internal scene of each section can be seen from the disconnected side.

Xu Xin rode Hui Hui across the air and glanced twice.

And this second giant ship is undoubtedly empty.

"Go to that one."

The wreckage of the third giant ship is still in this huge sinkhole.

However, the location of the wreckage is at least one kilometer away from the two ships.

Fortunately, Hui Hui was very fast and flew over in just ten seconds.

As soon as it flew into the sky, Xu Xin saw the difference in the wreckage of this giant ship.

The inside of the giant ship was fundamentally different from the previous two ships. It was not completely blown up.

Rather, there are these barriers.

"Go in, Huihui."

"ah--"

Hui Hui leaned over and sprinted, getting in through the hole in the wreckage.

Then, with just one glance, Xu Xin saw...

Rows of tanks neatly displayed deep in the wreckage of the giant ship.

The giant ship is tilted as a whole, but this does not prevent these tanks from being arranged neatly at an angle.

Each tank seems to have a special "parking space", and at this time, that parking space is lit up.

It looks... like it's being recharged.

"...!"

Xu Xin's eyes narrowed.

Lit up?

Recharge?

This giant ship is even using energy!

The power system of this giant ship is actually still functioning?

No……

Most of the places inside this giant ship are empty.

There are layers and equipment only where the tanks are located.

That is, only there is intact.

This is probably because the area where the chariots are stored is likely to be constructed with the same materials as the chariots.

If the tank can remain intact under the bombardment, this area will naturally remain intact.

Perhaps, even the energy needed to charge these tanks now is independent of this area.

It should be independent.

The power system of this giant ship should have been destroyed, otherwise it would have flown away long ago.

"So, our previous guess was correct, and even... the real situation is even more serious."

Xu Xin frowned.

"These tanks can actually be charged."

Xu Xin and Hui Hui were now less than a hundred meters away from the tanks and could see the appearance of these tanks relatively clearly.

These tanks are completely enclosed.

There isn't even a piece of transparent glass, it's just a big metal box.

Even...Xu Xin couldn't see the door.

These chariots should not need a controller to control them.

These are automatic combat vehicles.

Therefore, these tanks should rely on instructions to attack.

That is to say...

If the command of these chariots to "destroy the World Tree" is still there, when they charge up their energy, they are likely to set off again and attack the World Tree!

This is a big deal!

This is a tank that cannot even be damaged by nuclear weapons!

"What should I do...teleport? Teleport these chariots away?"

Xu Xin frowned and thought.

But at this time, his mind was in a mess and he couldn't think of a reason at all.

because……

"...Hui Hui, we have to leave quickly."

He rubbed his abnormally dry nose, and then there was blood on his hand.

Moreover, he already had a splitting headache.

He had already taken the pill once before entering this third giant ship.

Unexpectedly, just a few minutes after entering, this situation happened again.

He had to take another pill.

The situation has improved a lot, but it's not a good place to stay for a long time.

"Huihui, let's go out."

After flying out of the giant ship, Hui Hui stopped outside the wreckage of the giant ship.

"Huihui, are you feeling uncomfortable?"

"ah……"

Hui Hui's voice was obviously much weaker.

Xu Xin immediately threw two pills into its mouth.

"Ah...mom...ah--"

A few seconds after Huihui took the pill, he immediately flapped his wings twice.

Apparently, it recovered.

Xu Xin has also placed coordinates here.

"Let's go back."

Xu Xin rode Hui Hui straight into the sky, and then flew towards the World Tree at high speed.

Soon, twenty minutes later, we returned to World Tree.

Xu Ying rests in a tree house around the World Tree.

Li Wenxi had already entered the World Tree once and came out again, and was waiting in the tree house with Xu Ying.

Seeing Xu Xin returning, the two of them immediately swung down from the tree house.

"elder brother!"

"How's it going? You weren't hurt by the radiation, were you?"

"It's okay. But we have something."

Xu Xin told the two of them what he found there.

"Can it still be charged?" Xu Ying frowned, "This is a bit troublesome..."

"Fortunately, we thought of it and went to investigate." Li Wenxi said with some fear and some happiness, "If we hadn't discovered this, our World Tree would have been destroyed again!"

"Well, so, this matter needs to be resolved first."

Xu Xin looked at Xu Ying: "Yingying, I plan to return to the alien invader base tomorrow to investigate. In one day, even if there is chaos there, the dust has almost settled."

"...Well, that's fine." Xu Ying nodded lightly, "Now, it's not a big problem for me to persist for a day. You guys should go back to World Tree. Just now Wang Lei and the others came out several times to ask about the situation and asked you why you still have to return. Don’t go in.”

"What about you?"

"I'll be fine just here." Xu Ying sat on the bed and stretched.

"Yingying, please follow us inside." Li Wenxi held her hand and said, "Just use the method you think of."

"That method... may not be reliable, and it may have certain risks. I..." Xu Ying hesitated.

"Didn't you still confidently say it was reliable before? You even explained the principle to me."

Xu Xin also grabbed one of her hands: "Let's go, your current state requires a long rest. You only have one day to stay outside, why not go back to World Tree to rest."

"Well...that's fine..."

The three of them came to the roots of the World Tree.

"I will enter first and adjust the time flow rate of World Tree to be consistent with the outside world. Then I will contact you directly through communication. You can just come in when the time comes."

"good."

Xu Ying and Li Wenxi watched Xu Xin enter the World Tree.

Then, within ten seconds, Xu Xin's call came through.

"Okay, you can come in."

Xu Ying and Li Wenxi looked at each other.

Li Wenxi could clearly feel the sweat on Xu Ying's palms.

"Don't be nervous, it'll be no problem."

The two entered the roots of the World Tree.

After Xu Ying fully entered, she stood still for two seconds, and then her eyes lit up!

"Okay! Okay! Success!"

she said excitedly.

Although in her theory, this thing has a 90% probability of being feasible.

If not, she wouldn't have chosen to enter. It would be safer to wait outside for a day obediently.

However, I am still a little worried.

After all, if it failed, she might be wiped out directly.

Fortunately, it was successful.

"Already in? Go up first."

"Um!"

The two took the vine ball elevator and arrived at the inner space of the World Tree.

It is still a vast area and land, and it has reached 10,000 meters into the sky.

There's not much difference from before.

In front of them, there was a town that was under construction!

Large areas of low-rise buildings have also been erected.

After all, it had been more than an hour since they had been outside, and four or five days had passed inside the World Tree.

These low-rise buildings were all temporarily built to provide temporary housing for tens of thousands of people.

However, neither of them focused on this.

"How are you doing? Do you feel any discomfort?" Li Wenxi asked with concern.

"No." Xu Ying shook her head.

"Then I am going to restore the flow of time in the World Tree now." Xu Xin said in the communication.

"...Well, you can recover."

"..."

"..."

"Have you recovered?" Xu Ying asked, wagging her lips.

"It has been restored a long time ago." Xu Xin smiled on the other side of the communication line, "It seems that you are indeed fine."

"...Yes, is that so..."

Xu Ying breathed a long sigh of relief, and finally a relaxed smile appeared on her face.

"It seems that I can live for a while longer..."

She could feel that in this world tree, the progress of her body's time and space disorder was greatly suppressed.

No, maybe it's not suppression, but the degree of space-time disorder, which should be related to the time flow rate of the outside world.

She stayed inside the World Tree for a hundred days, and only one day passed in the outside world, and the progress of her body's time and space disorder was only one day.

This was also the main reason why she wanted to enter the World Tree.

In the World Tree, her last lifespan can be extended a hundred times!

Now, she succeeded!

"Then let's stay here and rest for a while."

Li Wenxi smiled and pulled her towards the town.

People were coming and going, and the World Tree was very lively.

…

Time flies by.

Life in World Tree is much more comfortable than outside.

There is a lot of time for them to use and waste.

Soon, three months passed.

"Yingying, it's time for us to take action."

Xu Xin folded her hands on her chest and said helplessly as she looked at Xu Ying, who was lying on the sofa rubbing the handle.

After living in the World Tree for a few days, this guy fell into this lazy state.

Now she doesn't even have to go out, she just stays at home and plays all day long.

"Hey..."

Coco lay in front of Xu Ying, turned over, exposed her belly, opened her mouth and yawned.

"Huh? It's time to take action?"

"We still have those tanks to deal with, and we have to go to the alien invader's base to take a look. Should you..."

Xu Ying put down the controller with some lack of interest and said: "How about, brother, go and help me take a look, I don't want to move..."

"You..." Xu Xin laughed angrily.

"Oops, just kidding."

Xu Ying stood up from the sofa and stretched.

She was wearing casual clothes, shorts and short sleeves, with her belly button exposed, her hair was a little messy, and she looked unkempt.

Like Coco, he even opened his mouth and yawned, tears about to come out.

"Well...are we finally going to take action?" She rubbed her eyes.

"Well, we have prepared everything, it's time to set off." Xu Xin looked at her appearance, shook his head, and said helplessly.

He now really suspected that these three months of leisure had made his sister forget what she wanted to do before.
