Chapter 504 Upgrade!

Zhong Maiyun is also a capable person. After making up her mind, she started to upgrade the shelter without any hesitation.

She actually had all the conditions ready, and she only needed to take the last step.

With Qi Yuan as her backer, she could feel more at ease.

Soon, a white light enveloped the shelter.

The upgrade began.

Although she had experienced many shelter upgrades, she was still shocked to see this scene again.

Soon, subtle changes occurred in the entire shelter space.

He could clearly feel that the land seemed to be breeding life, and strong vitality was coming from all directions.

In the brown-black soil on the ground, there was obviously no plant growing, but it seemed that countless lives were surging.

Then the most obvious thing was that there seemed to be a vine plant growing on the walls around the entire shelter, as if to put a layer of vine armor on the entire shelter.

Zhong Maiyun looked at the changes around her, her face full of tension.

When the white light slowly dissipated, the entire shelter had undergone earth-shaking changes.

The walls around and the ceiling were all covered with vines that were clinging to the walls and emitting a faint white fluorescence.

In this case, even without an artificial sun, it was very bright.

The second thing was the soil underground. After Zhong Maiyun leaned over to check, she immediately showed an extremely happy expression.

"It's this kind of soil! I didn't expect it to be successful."

Qi Yuan also squatted down and learned to grab a handful of soil. Unfortunately, after studying it for a long time, he didn't understand anything.

"Is there anything special about this soil?"

Zhong Maiyun smiled and looked at the soil in his hand. She explained absentmindedly: "The soil in the Dream Garden has a special function. It is very suitable for cultivating plants and guiding the direction of plant mutation, so it is very important."

"For example, guiding the small-leaf cattail to be unable to reproduce, making the Qingyuan jade fruit more suitable for breakthrough, and making the Minglu flower have a better treatment effect... all depends on the role of this soil."

"I see. Now the entire shelter is made of this soil. Aren't you rich?"

However, when Qi Yuan finished speaking, Zhong Maiyun's smile suddenly froze on her face.

She looked at Qi Yuan with some trepidation and said, "I may not be able to live here anymore."

"Why?"

Qi Yuan was confused for a moment.

"This kind of soil is extremely active and can easily cause plants to mutate. If it is not controlled by humans, it is likely to mutate into strange things."

Zhong Maiyun thought of a very serious problem and her expression immediately became serious.

This kind of soil is indeed very good, but the disadvantages are also very obvious.

If it is not controlled, the entire ultra-deep underground shelter will become the world of mutated plants.

However, it is almost impossible to take care of the entire 3km area.

So, Zhong Maiyun said that it is impossible to live here.

To a certain extent, the change of this ultra-deep underground shelter should be a failure.

Because it is completely out of control.

Qi Yuan also became serious and said, "Is there any way to control it?"

Zhong Maiyun thought for a long time and could not give an answer.

Finally, he only said: "Let's take it one step at a time. It is definitely impossible to completely control the soil. We can only find a way to control plants."

"How to control plants?"

"I don't know. God knows what kind of plants will mutate. It's just like raising a Gu. No one knows what the result will be in the end."

Hearing such desperate news, Qi Yuan was a little embarrassed for a while.

It was he who encouraged Zhong Maiyun to upgrade the shelter, but he didn't expect the result to be so terrible.

As if seeing Qi Yuan's danger, Zhong Maiyun became more free and easy, and said indifferently: "To a certain extent, it is actually a success. The original 100㎡ dream garden has been directly expanded to a radius of 3km."

"Okay, you will live in the underground shelter in the future?"

Qi Yuan was still a little worried.

"Yes, you transfer some guardian thorns here to surround the hole of the same deep vortex sand, so that it will be convenient to collect resources in the future."

After making such arrangements, Qi Yuan directly transferred a rare guardian thorn here.

And Zhong Maiyun started moving.

At the same time, all kinds of plants in the original dream garden were transferred out and sent to the underground shelter.

Looking at the sunny underground shelter with thousands of acres of fertile fields, Qi Yuan couldn't help but sigh inexplicably.

By the way, he suggested: "Mai Yun, why don't you upgrade the underground shelter as well?"

This sentence caused Zhong Mai Yun to roll her eyes: "Are you going to force me to be homeless completely?"

Qi Yuan smiled awkwardly and didn't care too much. He said: "Using props as the core of the upgrade, the uncontrollability is still too great. But if you use resources as the core, it is still very stable."

Zhong Mai Yun was speechless for a moment.

Considering that the underground shelter is only level 5 and the concentration of spiritual energy is only good, it is indeed not conducive to later development.

After some thinking, Zhong Mai Yun finally made a decision: "Okay, what should I use as the core this time?"

Qi Yuan didn't dare to be careless. After careful consideration, he said: "Xiran, it's more reliable."

As he said, Qi Yuan took out two large groups of resources from the dimension backpack.

It was just caught from the vortex.

The smaller ball was a thousand kilograms of Xirang, which had a brown-black luster and was still moving slightly, which was very magical.

Another mass weighed several tons, but the contents were very messy.

The main component was rare gravel, similar to "quicksand soil", but of higher quality, and there were a lot of them in the vortex.

And in the gravel, there were also a lot of other ores.

Qi Yuan searched and finally found two perfect crystals in the gravel.

Unlike the simplicity of other ores, these two crystals were dazzling, like crystals, emitting crystal light.

Through the identification device, you can directly view the information.

[Name: Jinze Pushi (perfect grade)

Function: There are a lot of earth-attribute resources and gold-attribute resources, which are condensed for a long time under strong pressure.

Introduction: Extremely hard. Contains a lot of gold and earth-attribute energy. ]

This kind of crystal does not have any special function, it is just a gold-earth crystal formed under long-term high pressure.

However, Qi Yuan was not disappointed.

After all, it is perfect grade, even if it is used to cultivate "bone species", it is a very good choice.

Qi Yuan looked at Zhong Maiyun and said helplessly: "It seems that we can only use Xirang."

Zhong Maiyun did not refuse, and directly took a large ball of Xirang and spread it on the underground shelter.

It was still a similar process, but the changes were completely different.

Using Xirang as the core of the upgrade, the process was very smooth, and the result was just as they expected.

The soil of the entire underground shelter was transformed into a soil similar to Xirang.

Unlike Xirang, this soil has no spirituality and only has the function of accelerating the growth of crops.
