Chapter 498 Give You a Blue Sky

Two days later, Zhang Hao bid farewell to the first train that transported rainfall equipment.

The train carried hydrogen balloons, compressed hydrogen tanks, and a mixture of a large amount of ultrafine stone powder, salt powder, and flour. The powder is easy to manufacture, and the production volume can be large.

As for dry ice, silver iodide, etc., with Dayang Group's current technical reserves, it is still somewhat difficult and costly. In contrast, it is not as affordable as powder. And the front line is thick with fog, and the powder is enough to trigger rainfall.

Accompanying them were hundreds of temporarily trained skilled workers from the Zhang family. The real skilled workers of the Zhang family are all baby lumps, and Zhang Hao will not let them take risks easily, especially if they leave the country of Qixia.

However, even temporarily trained technical workers have a certain technical foundation. These people are the backup force of the Zhang family, and they are equally precious.

And this time, the team leader among the many members of the Zhang family turned out to be one of Zhou Xueyao's maids, Xiaoyue and Zhou Xiaoyue. The two servant girls followed Zhou Xueyao's surname.

Xiaoyue is no longer dressed as a girl, but as a rich lady, full of confidence and high spirits. Xiaoyue and Xiaozhu are in charge of the hot air balloon and hydrogen balloon projects.

This time out, Xiaoyue won the lottery and got the chance to show off.

Sitting in the carriage, Ming Xuzi and Hong Yunzi looked at Zhou Xiaoyue with some doubts. Neither of them expected that a little girl was responsible for the solution given by Zhang Hao.

Xiaoyue's current cultivation is only at the peak of the Foundation Establishment Stage, in the eyes of Ming Xuzi and Hong Yunzi, she is really a little girl. On the current battlefield, it is also a small grass.

In the end, Zhang Hao actually said that Xiaoyue was in charge of this incident, completely.

The two were watching, but Xiaoyue showed a generous and faint smile, and quietly looked down at the book. The book in her hand is the research manual led by Xiaozhu and herself, and it is the research on the atmosphere and so on. The two little girls are already progressing to become environmental and meteorological experts.

Behind Xiaoyue, there were several young people in their teens and twenties, and everyone was discussing the upcoming plan in low voices.

Ming Xuzi and Hong Yunzi thought about it, but they still didn't speak.

It took the train less than three days to arrive at the front line, and from a long distance, there was a fog like a moat stretching between heaven and earth.

Ming Xuzi saw that everyone was unloading a large amount of goods, he came to Xiaoyue and said, "Xiaoyue, do you want me to take you to the sky to see the situation?"

Xiaoyue smiled and shook her head: "Thank you, senior, I will probably check with my eyes, if I want to detect the situation here, I need to go above the aura layer to find out clearly.

And above the aura layer...do you want to go up and have a look, senior? "

Above the aura layer? Ming Xuzi thought for a while, longing flashed in his eyes, and he finally nodded. Although he was underestimated by a little maid, he really wanted to go to the top of the aura layer to see it.

As the masters of the transformation stage, everyone has more or less hit the top of the aura layer. But it is a pity that even at the peak of transforming gods, they can only stay in the sky for a while.

Above the spiritual energy layer, without the spiritual energy, even in the stage of transforming into a god, there is nothing that can be done. Out of the water, whether it is an ordinary small fish or a powerful shark, they can only fall.

The scene quickly assembled 20 huge hydrogen balloons. The hydrogen balloon rose slowly, and giants with a height of more than 50 meters flew slowly into the sky.

On the ground, many soldiers of the Xuanzhen Sect coalition opened their mouths wide, looking at these balloons in surprise.

"Are the hot air balloons this big now?" Nangong Zhi asked Gu Xingdong next to him.

Gu Xingdong was a little embarrassed, "This...it's also the first time I've seen such a hot air balloon. In fact, Dayang Group is developing so fast that it's too fast for my eyes to see. I can still recognize this thing as a hot air balloon. It's not easy. .”

"I recognized it..." Nangong Zhi rolled his eyes.

"Hey..." Gu Xingdong laughed triumphantly, without any embarrassment.

And in the rear of the Xuanzhen Sect coalition forces, twenty huge balloons slowly lifted into the air, but the middle one rose the fastest. Xiaoyue stood in the hanging basket and used the flag to direct the movements of the other balloons.

These balloons are different from the balloons that the Dayang Group collects aura, and add a fan driven by aura, which can be used as power. The fan is not big, but the power is considerable. Especially now that you are in the aura layer, you can also use magic to drive the balloon to move. Cultivators, they are all cheating lives.

Under Satsuki's command, the balloon slowly rose into the sky. It is more than 300 kilometers away from the Xiaoyao faction's battle line, and it is very safe - because of the mutation of the mist formation, neither side can cross this area.

This super foggy area with a length of more than 6,000 kilometers has become a temporary "truce line" for both sides.

With the help of this 'truce line', the Xiaoyao faction's army is quickly correcting and rearranging. Because it temporarily blocked the crazy attack of the Xuanzhen Sect coalition forces, especially the Qixia Kingdom Army, the Xiaoyao faction was able to breathe.

The longer the time, the more unfavorable it will be for Xuanzhen Sect. The "oppressive stance advantage" obtained by the previous crazy attack will gradually be lost.

That was in exchange for tens of millions of shells! The military expenditure of these shells alone is as high as more than 30 million high-grade spirit stones!

Therefore, the Xuanzhen Sect urgently needs to solve this line of defense that is more than 6,000 kilometers long.

The hydrogen balloon rose slowly, the speed was not very fast, but it was firm and steady, passed through the floating clouds all the way, and gradually reached the high altitude where the aura was thin, the top of the aura layer.

Here, the gravity began to increase, the spiritual energy began to fade, and the stage of transforming gods also felt a certain degree of depression here.

Xiaoyue's complexion was already a little pale, but it was just a conditioned reflex - the little girl was a little scared, but also a little unspeakably excited.

With the foundation of the foundation, this height and the environment here will not cause her much pressure. At most, it can only increase the gravity by ten times. For the foundation building period, it can survive normally. Even if the high air is cold and the air is relatively thin, it is not a problem for the foundation building period.

The balloon continued to rise, gradually surpassing the height of the fog. Here, it has reached an altitude of seventy kilometers. Xiaoyue looked at the altimeter and it showed an altitude of 71160 meters.

Looking down at the earth from here, it is like a picture scroll, no mountain peak can break through the height of the aura layer - it will be crushed by its own gravity.

But the fly in the ointment is that a 'cloud dam' appeared in the east, blocking this magnificent picture of mountains and rivers.

Above this piece of cloud and mist, it rolled like a sea of ​​fog; because the higher place had lost the support of spiritual energy, the influence of the formation disappeared, and the climate returned to normal.

After observing for a long time, Xiaoyue was sure that it was safe, and took the lead to fly forward.

Here, the spell has lost its effect because there is no aura to support it - of course the practitioner can rely on the true energy in the body to do it, but it consumes too much.

So at this time, the power of the machine began to be magical.

The fan driven by the spirit stone whirred, pushing the hot air balloon forward. Xiaoyue carefully followed the wind, trying to reduce resistance and increase speed.

When she came to the upwind of the 'Sea of ​​Fog', Xiaoyue tested the wind direction and speed, etc., and smiled with satisfaction, and immediately used the order flag to direct everyone to be busy.

We sprinkle bags of mixed powder on the fan, and the fan grinds and lifts the powder up into the wind and into the atmosphere.

All of a sudden, gray 'air currents' in the sky began to circle, gradually spreading along the direction of the wind, and the powder itself was slightly heavy, and would gradually fall down.

Twenty worlds moved forward side by side, and a large amount of powder was sprinkled, and long gray-white rivers appeared in the sky.

The gravity above the aura layer is strong, the powder falls quickly, and soon the powder comes into contact with the mist. Suddenly, a change appeared, a large amount of fog quickly thinned and gathered together, and tiny ice crystals appeared in the sky. There are even snowflakes etc. appearing.

There is no aura in the sky, but the primordial spirit of the master of transformation is not affected. Ming Xuzi and Hong Yunzi stared at this new change in astonishment.

The balloon moved forward slowly, but the fog behind it changed rapidly. Half an hour after the balloon flew out in front, the fog behind had turned into dark clouds, and even lightning rolled over.

When Xiaoyue saw the lightning, her expression changed immediately, and she immediately waved the command flag. Everyone stopped working immediately, and the balloon began to quickly leave the range of clouds and lightning.

However, the speed of the balloon is really too slow.

Ming Xuzi looked stunned, and he was shouting excitedly at this moment: "Why do you want to leave, come more, come more!"

But seeing the fog behind, it has already begun to 'collapse' - the fog that was white before, like a sea of ​​fog, began to condense into dark clouds and began to droop. There seems to be a black hole in the center of the entire sea of ​​fog. And this loophole is expanding rapidly.

Not only that, but in the center of the loophole, lightning has already begun to appear. At this time, snowflakes, ice crystals, raindrops, etc. can already be seen appearing.

Such a scene is a bit beyond the experience of a master in the transformation stage. Just sprinkle a handful of powder, and it will produce such a change!

Thinking about how much the Xiaoyao faction spent to build a defense line of 6,000 kilometers and 12,000 miles long, and it was cracked by a few handfuls of clay powder like this, Daoist Mingxu himself feels heartbroken for the Xiaoyao faction!

You know, the entire front line is only about 10,000 kilometers, and the Xiaoyao faction frantically created a truce line of 6,000 kilometers, all of which were made with formations and so on. Its consumption is definitely an astronomical figure. Although the black iron technology has improved now, it is a spiritual material after all, no matter how cheap it is, it will not be the price of cabbage.

What's more, to refine the formation foundation, you need red copper, fine gold and other assistance.

Seeing such a spectacular scene, Ming Xuzi really wanted to continue. He couldn't understand why Xiaoyue was so timid, and when thunder struck, she ran away in fright?

But Xiaoyue didn't care about explaining, she waved the command flag in her hand hurriedly, and all the balloons fled here at the maximum speed. And in the process of escaping, no powder was sprinkled.

The hydrogen balloon began to deflate, and the balloon quickly fell to the aura layer. Everyone's spells were able to exert 30% of the effect, and hurriedly urged the balloon to escape crazily.

In the rear, the sea of ​​fog is being swallowed by darkness, the dark clouds spread rapidly, and the lightning spreads wildly like branches.

Suddenly, a flash of lightning crackled and quickly hit a hydrogen balloon!
