Two days later, Zhang Hao saw off the first train that transported rain equipment.
The train carried a mixture of hydrogen balloons, hydrogen compression tanks, and a large amount of ultra-fine stone powder, salt powder, flour, and so on. Powder production is easy and the production volume can be large.
As for dry ice and silver iodide, the current technology reserves of Ocean Group are still somewhat difficult and costly. In contrast, it is not as affordable as powder. And the frontline is densely fogged, and the powder is enough to trigger rain.
Along with the departure, there were hundreds of temporary trained technical workers in the Zhang family. The real skilled workers of the Zhang family are all pimples. Zhang Hao will not let them easily take risks, especially to leave the country of Qixia.
However, even the temporary training of skilled workers also has a certain technical foundation. These people are the backup forces of the Zhang family and are equally precious.
This time, the leader of many Zhang family members turned out to be Zhou Xueyao's maid, Xiaoyue and Zhou Xiaoyue. The two maids followed Zhou Xueyao's surname.
Xiaoyue is no longer a girl dress, but a rich girl's dress, full of confidence and high. Xiaoyue and Xiaozhu are responsible for the hot air balloon and hydrogen balloon projects.
This time when going out, Xiaoyue won the battle and got a chance to let it go.
Sitting in the carriage, Ming Xuzi and Hong Yunzi looked at Zhou Xiaoyue with some doubt. Neither of them thought that the solution given by Zhang Hao was actually taken care of by a little girl.
Xiaoyue's current cultivation practice is only the peak of the foundation period. In the eyes of Ming Xuzi and Hong Yunzi, it is really a little girl. It is also a small tender grass placed on the current battlefield.
As a result, Zhang Hao actually said that Xiao Yue was responsible and complete this time.
The two were reading, but Xiaoyue showed a generous, faint smile and quietly looked down at the book. The book in her hand is a research manual led by herself and Xiaozhu, and is a study of the atmosphere. The two little girls are already making progress to environmental and meteorological experts.
Behind Xiaoyue, there are still a few young people in their twenties and twenties, and everyone is whispering about the upcoming plan.
Mingxuzi and Hongyunzi thought about it, and after all they still didn't speak.
It took less than three days for the train to reach the front line, and Lao Yuan saw the mist as if the sky was between heaven and earth.
Ming Xuzi watched the crowd unloading a large number of goods. He came to Xiaoyue and said, "Xiaoyue, would you like me to take you to heaven to see the situation?"
Xiaoyue smiled and shook her head: "Thank you, Senior, I might have a visual inspection. If I want to detect the situation here, I need to go to the top of the Aura to find out.
And above the aura layer... Do seniors go up and see? "
Above the aura layer? Ming Xu Zi thought about it, his eyes flashed with longing, and finally nodded. Although he was shown to the little girl by a little maid, he really wanted to take a look above the aura.
As masters of the magic period, everyone more or less impacted above the aura. But unfortunately, even the peak of Huashen can only stay in the sky for a while.
Above the Reiki layer, there is no Reiki, and even the divine phase is powerless. After leaving the water, whether it is an ordinary small fish or a powerful shark, it can only fall.
The scene soon assembled 20 huge hydrogen balloons. The hydrogen balloon ascended slowly, and giant behemoths as high as more than fifty meters high flew slowly into the sky.
On the ground, many soldiers of the Xuanzheng Allied Forces opened their mouths and looked at these balloons in surprise.
"The hot air balloons are so big now?" Nangong Zhi asked Gu Xingdong next to him.
Gu Xingdong was a little embarrassed, "This... this is the first time I have seen such a hot air balloon. In fact, the Ocean Group is developing very fast, and it is a bit dizzying. I can still recognize this thing as a hot air balloon, which is not easy anymore. ."
"I recognized it..." Nangong Zhi rolled his eyes.
"Hey..." Gu Xingdong laughed smugly, without any embarrassment.
At the rear of the Xuanzheng Allied Forces, twenty huge balloons slowly lifted off, but the middle one took off the fastest. Xiaoyue stood in the gondola and used the flag to direct the movement of the remaining balloons.
These balloons are different from the Reiki-collected balloons of the Ocean Group, and they have added Reiki-driven fans that can be used as power. The fan is not big, but the power is considerable. Especially in the aura layer, you can also use magic to urge balloon movements. Cultivators are all open lives.
Under the command of Xiaoyue, the balloon slowly rose into the sky. It is more than three hundred kilometers away from the frontline of the Xiaoyao faction. It is very safe-because of the variation of the fog formation method, it is impossible for anyone on both sides to cross this area.
This super-mist zone of more than 6,000 kilometers has become a temporary "truce line" for both sides.
With the help of this "truce line", the troops of the Xiaoyao faction are rapidly revising and re-arranging. Because it temporarily blocked the crazy attacks of the Xuanzheng Allied Forces, especially the Qixia State Army, the Xiaoyao faction was able to breathe.
The longer the time, the more unfavorable to Xuanzhenism. The "advantages of oppression gestures" achieved by previous crazy attacks will gradually be lost.
That was exchanged for tens of millions of shells! The military expenditures of these shells alone amount to more than 30 million top-grade spirit stones!
Therefore, Xuanzhenism urgently needs to solve this defense line with a length of more than 6,000 kilometers.
The hydrogen balloon slowly rises, the speed is not very fast, but it is very firm and very stable. It has passed through the floating clouds all the way and gradually came to the top of the aura and thin aura.
Here, gravity begins to increase, Aura begins to subside, and the Huashen period also feels a certain depression here.
Xiaoyue's face was a little pale, but it was just conditioned reflex-the little girl was a little scared, but a little unspeakable excited.
There is a foundation for foundation, this height and the environment here, will not cause much pressure on her. At most, it only increases the gravity by ten times. For the foundation period, it can survive normally. Even if the high air temperature is cold and the air is relatively thin, it is not a problem for the foundation period.
The balloon continued to rise, and the height gradually exceeded the height of the fog. Here, it has reached an altitude of seventy kilometers. Xiaoyue looked at the altimeter, which showed an altitude of 71160 meters.
From here, looking down at the earth, like a scroll, no mountain can break through the height of the aura-it will be crushed by its own gravity.
However, what is inadequate is that a ‘cloud fog dam’ appears in the east, blocking this magnificent landscape of mountains and rivers.
Above this cloud of mist, it rolls like a sea of ​​fog; the higher part has lost the support of the aura, causing the influence of the formation to disappear and the climate to return to normal.
Xiaoyue observed for a long time and determined that it was safe, and took the lead to fly forward.
Here, the spell has lost its effect, because there is no aura support-the practitioner can of course rely on the true yuan practice in the body, but it is too expensive.
So at this time, the power of the machine began to be magical.
The fan driven by the spirit stone turned hula, pushing the hot air balloon forward. Xiaoyue carefully follows the wind, reducing resistance and increasing speed as much as possible.
Coming to the upper hand of ‘Wu Hai’, Xiaoyue tested the wind direction, wind speed, etc., all smiled with satisfaction, and immediately commanded everyone to be busy with the command flag.
Everyone sprinkled a bag of mixed powder to the fan. The fan crushed and lifted the powder, and then entered the wind and the atmosphere.
Suddenly the sky of gray ‘air currents’ began to hover, gradually spreading in the direction of the sky wind, and the powder itself was slightly heavy, and it would gradually fall.
Twenty globes marched side by side, and a large stream of gray appeared in the sky as a large amount of powder was spilled.
The gravity above the aura layer is large, the powder falls quickly, and soon the powder comes into contact with the mist. Suddenly changes appeared, a large amount of mist quickly thinned and gathered together, and tiny ice crystals appeared in the sky. There are even snowflakes.
There is no aura in high altitude, but the primal spirit of the master of transformation is not affected. Mingxuzi and Hongyunzi stared dumbfounded at this new change.
The balloon slowly moved forward, but the rear fog quickly changed. After half an hour of the balloon in front, the rear fog had turned into a dark cloud, and even lightning rolled.
As soon as Xiaoyue saw a lightning appear, his face suddenly changed, and he immediately waved the flag, everyone stopped working immediately, and the balloons began to quickly leave the range of clouds and lightning.
However, the speed of the balloon is too slow.
The stunned Ming Xuzi looked next to him, and he was shouting excitedly at this time: "How to leave, come again, come again!"
But seeing the fog behind, it has begun to'collapse'-the mist that was still white, like the sea of ​​mist, began to condense into a dark cloud and began to sag. A black hole appeared in the center of the entire Wuhai. And this loophole is expanding rapidly.
Not only that, lightning has appeared in the center of the loophole. At this time, you can already see snowflakes, ice crystals, raindrops and so on.
Such a scene is a bit beyond the knowledge of the master of the Huashen period. Even if a handful of powder is sprinkled, such a change will happen!
Think about how much it cost the Xiaoyao faction to build a defense line of 6,000 kilometers and 12,000 kilometers, and it was just cracked by a few pieces of mud powder.
You know, the entire front line is only about 10,000 kilometers, and the Xiaoyao faction has created a 6,000-kilometer truce crazy, all of which are made by the formation method. Its consumption is definitely an astronomical figure. Although the technology of black iron has improved now, it is the spirit material after all, and it will not be the price of cabbage even if it is cheap.
Moreover, to refining the formation, it also needs red copper, fine gold and other auxiliary.
Seeing such a magnificent scene, Ming Xuzi wanted to continue. He didn't understand why Xiaoyue was so courageous, so he thundered and ran away scared.
But Xiaoyue couldn't care about the explanation. The flag in her hand waved hurriedly, and all the balloons fled here with maximum speed. And no powder was scattered during the escape.
The hydrogen balloon began to deflate, and the balloon quickly fell to the aura, and everyone's spells could play a 30% effect, quickly urging the balloon to escape.
Behind, the sea of ​​fog is being swallowed by darkness, dark clouds spread rapidly, and lightning spreads like a tree branch.
Suddenly, a flash of lightning flashed through and quickly hit a hydrogen balloon!
