The second uncle tried to persuade him many times, but Li Yu still insisted on his original idea.
The existence of the northern border can bring considerable benefits to the Da Zhangshu Base.
Whether from a long-term perspective or a strategic perspective, TC is a very unwise choice.
But.
Li Yu also has his own considerations.
He wasn't just acting out of impulse.
Originally, the Northern Federation was much larger than the Great Zhangshu Base and had very strong war potential.
Once the people of the Northern Federation figure out the zombie attracting agent one day, and even as they send people to infiltrate the Da Zhangshu base, one day the Da Zhangshu base will face unbearable consequences.
The Northern Federation feels like its tail is too big to lose.
What's more, the feud between the Northern Federation and the Federation is so deep that it affects one belt and three.
He just killed a few leading people, or some people, but there is no guarantee that other people will be drawn out one day. And if these people are deeply hidden, then as time goes by, when he reaches a certain level at the Da Zhangshu base,
Height will always lead to unpredictable consequences.
This is what Li Yu is most afraid of.
When he does things, he always pays attention to cutting through the mess with a sharp knife.
Only by eradicating the root cause can more countless troubles be avoided.
Therefore, he has made up his mind.
TC is a foregone conclusion.
.....
Seeing that he couldn't be convinced, the second uncle had no choice but to accept it, and began to think about how to make it more perfect according to Li Yu's idea.
at the same time.
Dazhangshu Base, in the Second Outer City.
A helicopter slowly took off.
In the thin fog, the helicopter slowly rose to an altitude of more than thirty meters.
And this height is exactly the height of the fence at the Da Zhangshu Base.
So far, Lao Bi can still see clearly when he looks around.
Although there is fog around, it is not that dense.
Further up, you will fly into an invisible thick fog.
Lao Bi tensed his mind, and then said to He Ma in the cabin: "Get ready to release liquid nitrogen!"
"Okay." He Ma replied quickly.
The helicopter slowly rose again, and soon it entered a thick fog.
Lao Bi's nerves were tense. He firmly stabilized the helicopter and maintained a straight upward posture.
Crash--
He Ma opened the hatch and at the same time put the mask he had prepared on his face.
He was pulling the liquid nitrogen spray pipe, and a safety belt was tied around his body.
He staggered to the cabin door.
呲呲呲——
Liquid nitrogen rose and sprayed out one after another, swaying downwards due to the influence of gravity and wind.
With the action of liquid nitrogen, the heavy fog under the helicopter slowly dissipated.
When He Ma saw this scene, his eyes were full of excitement.
Sudden.
The fuselage shook violently.
He quickly held the handle on the side of the machine door with his hand and operated the liquid nitrogen spraying device with one hand. It was a little unstable, but he persisted.
I thought that I would have to find something to fix it after landing, otherwise it would be too tiring to just carry it with my hands.
After a few seconds, the helicopter returned to calm.
The effect of liquid nitrogen spraying is very significant.
Originally at high altitude, liquid nitrogen falling downwards can melt the fog to the maximum extent.
Lao Bi looked down through the car window, and the view from the ground was indeed much better.
My heart is excited.
So he controlled the helicopter to move in the sky.
Turned in a circle.
As the helicopter sprayed liquid nitrogen, everything on the ground gradually became clear.
And this is especially obvious to the people on the wall.
The patter of rain.
Feeling the rain falling from the sky, they raised their heads and looked at the helicopter in the sky.
Li Yu also stood on the outer city wall at this time and witnessed all this with his own eyes.
He breathed a long sigh of relief.
The method he thought of... works!
So I picked up the walkie-talkie and contacted Lao Bi: "Lao Bi, expand the area a little more and spray liquid nitrogen around the entire camphor tree base to see how long the lasting effect lasts?"
After Lao Bi received Li Yu's order from the intercom, although he was a little unsure, he still gritted his teeth and operated.
The helicopter moved in a wider range and flew around the Da Zhangshu base in a large circle.
When liquid nitrogen is sprayed from high in the air, as the wind blows, the liquid nitrogen is sprayed more evenly below.
It started to rain lightly throughout the base.
Before the end of the world, this was so-called artificial rainfall, but most artificial rainfall used dry ice.
The entire camphor tree base becomes clearer with the spraying of liquid nitrogen.
Lao Bi, who was hundreds of meters above the ground, almost jumped for joy when he saw such a clear base of the big camphor tree.
"Success! We succeeded!" Lao Bi shouted to Li Yu with some excitement.
Li Yu's mood also became much better.
So he picked up the walkie-talkie and asked: "How much liquid nitrogen is left in the helicopter, and how long can it last?"
After hearing Li Yu's question, Lao Bi quickly asked He Ma behind him and found out that there was about four-fifths left, and he could continue spraying for more than 20 minutes.
Li Yu ordered Lao Bi to spray half of the liquid nitrogen in the helicopter before flying down.
He wanted to see what effect he could achieve by spraying half of the liquid nitrogen.
It rained all the time.
Within a hundred meters of the fence, it also started to rain lightly due to the spraying of liquid nitrogen from helicopters.
However, a hundred meters away, there was still a thick fog.
Ten minutes later.
The entire camphor tree base took on a new look in the light rain.
A peculiar scene formed. There was thick fog all around with the Big Zhangshu Base as the center, but it was only drizzled here at the Big Zhangshu Base.
In light rain, the field of vision is not much better than in heavy fog.
Lao Bi piloted the helicopter and slowly landed in the Second Outer City.
Li Yu is waiting here with a silver box.
After the helicopter docked and stabilized, Lao Bi walked out and walked towards Li Yu with a smile on his face.
"City Lord, we succeeded!"
Li Yu nodded, and then shouted to Lao Bi:
"Quickly fill the other helicopter with liquid nitrogen and fuel, and prepare to leave for Oil City later."
He Ma, who was standing behind Lao Bi, quickly came out and said:
This chapter is not over yet. Please click on the next page to continue reading! "City Lord, can you give me ten minutes? I was too tired just now when I was spraying liquid nitrogen with my hands. I can't hold on for long and my hands are shaking. Please give me ten minutes."
Time, I’ll make a simple stabilizing device.”
Li Yu narrowed his eyes, turned his head and said to He Bing and Li Hang behind him: "Go and help him, and by the way, get another helicopter with a range of two thousand kilometers."
While Lao Bi and others were spraying liquid nitrogen in the sky, Li Hang and others who were originally at the Second Outer City Machinery Maintenance Factory also saw that the fog outside had dispersed a lot, so they all came out to check the situation.
After hearing Li Yu's order, Li Hang quickly said: "Okay, brother, I'll get it done right away."
Then he took Lao Zhou and He Bing to find He Ma and asked what stabilizing facilities needed to be added.
Seeing their leaving figures, Li Yu turned to his second and third uncles and said:
"The northern border must be eliminated. This time let me go with Lao Bi and the others in person."
The words just fell.
The second uncle and others quickly said:
"no!"
"Xiaoyu, you can't go!"
"Brother Yu, just let me go."
Li Yu was about to speak when his third uncle suddenly came forward.
Shake the rain hat and shake off the rainwater stained on it.
"Let me do this. I've been to the North, but you haven't been. You're not familiar with it." The third uncle looked straight at Li Yu.
Then without any explanation, he snatched the silver box from Li Yu's hand.
Li Yu saw his third uncle trying to grab the box and subconsciously held it tightly.
The two were in a stalemate for several seconds.
Li Yu was suddenly touched by his third uncle's eyes.
He let go of his hand involuntarily.
"Third uncle, you..." Li Yu felt helpless when he saw his third uncle holding the box.
The third uncle patted Li Yu on the shoulder and said:
"Xiaoyu, I said, anything can happen to anyone at our Da Zhangshu base, but you can't."
"Whether the Northern Federation should be wiped out entirely or should we adopt the method as your second uncle said, to be honest, I think it's fine."
"But I know that there can only be one voice in a base, and once a decision is made, it must be done immediately."
"Don't compete with me on this matter, I will do it well, and you don't have to worry about me."
After saying that, he shouted to Ant and the others:
"Brothers, let's go!"
After hearing Third Uncle's call, Lao Qin, Ant, Jackal, and Wu Jianguo stepped forward without hesitation.
Determined!
It seems that in their eyes, traveling thousands of kilometers to the north in such dangerous foggy weather is not a big deal.
They have always been like this. In the past, even if they were faced with a near-death mission, they would still stand up and carry out the task without changing their expressions.
Because if there is a call, the battle must go.
The rain is pouring.
Li Yu was a little moved. He suddenly understood what responsibility and dedication are.
Seeing that his third uncle was extremely determined, Li Yu had no choice but to accept it.
He walked forward and said to his third uncle:
"There are four potions in the box. Maybe when you, Third Uncle, arrive in the north, the fog will have risen. In order to ensure accuracy, you can put in all four potions, and the effect will be better."
The third uncle smiled and said: "I know, the amount is large and the food is full, and the food is enough at one time!"
Li Yu nodded and said, "That's almost the truth."
The second uncle sighed and directed He Chao and others to go over and help.
Try to fill the fuel and liquid nitrogen as quickly as possible.
soon.
Twenty minutes later.
The fuel in the helicopter has been filled, and the device for steady spraying of liquid nitrogen has been set up.
The third uncle persuaded Lao Bi to leave, and also asked He Ma and others not to go with him.
Five of them are enough.
Although Lao Bi and He Ma have already gone through the test just now, the test showed that they can take off and land with the help of liquid nitrogen spray in heavy foggy weather.
But along the way, there was heavy fog everywhere. They were sitting in the helicopter, like blind people, unable to see anything. This was an extremely frightening thing, and most people simply could not bear this kind of pressure.
Under the gaze of everyone, the third uncle carried the silver box and boarded the helicopter.
Even after stepping onto the helicopter, he smiled and waved to Li Yu and the others.
Lao Qin and his third uncle Ant shared a helicopter, while Jackal and Wu Jianguo shared a helicopter.
Uncle San never drags his feet when making decisions.
There was no sensational dialogue. After boarding the helicopter, he immediately started the helicopter.
Fly towards the direction of Oil City.
Li Yu looked at the helicopter flying higher and higher in the sky, his eyes full of worry.
"I hope you come back safely." Li Yu secretly said in his heart.
....
In a helicopter.
Lao Qin controlled the helicopter, and his third uncle sat in the co-pilot.
Picked up the walkie-talkie to contact Wu Jianguo in another helicopter, and simultaneously informed Lao Qin:
"The helicopter rose to an altitude of 3,000 meters above sea level, then flew north, maintaining an altitude of 3,000 meters along the way."
"receive."
"receive."
Without saying a word, Lao Qin immediately controlled the helicopter to fly upward.
Both of their helicopters determined each other's locations through electronic beacons.
It doesn't mean that they can't see each other and collide with each other.
The helicopter flew to an altitude of three thousand meters, and the temperature dropped to below zero.
For every 100 meters of altitude, the temperature will drop by 0.6 degrees.
The height of three thousand meters was calculated by Uncle San based on the terrain of the south.
If on the way from Da Zhangshu Base to Petroleum City, if we follow the position mark of the electronic beacon and follow the straight line, we will pass the highest altitude mountain range of only 2,200 meters.
They raised the helicopter to an altitude of 3,000 meters above sea level, so that there would be no risk of hitting buildings or mountains if flying at low altitude.
Although the temperature has increased and is a bit cold, it is safer.
Buzz buzz——
The helicopter headed in the direction of Oil City in a straight line.
...
The other side.
Ju Tianrui received the news from Li Yu at Da Zhangshu Base.
When he learned that the minister was coming to implement the plan to destroy the Northern Federation, he was so shocked that he opened his mouth and was speechless.
This chapter is not over, please click on the next page to continue reading! He has been to the Northern Federation, so he naturally knows how huge and densely populated it is.
But he didn't expect that he would still be destroyed in the end.
To be honest, he was still a little regretful.
However, he could also understand why the city lord made such a decision.
The reason why Ju Tianrui has always been so convinced of Li Yu is because Li Yu cares about his relatives and the people in the inner and outer cities of Da Zhangshu Base.
He understood that Li Yu really cared about their lives.
He is extremely tough externally and soft internally.
This made Ju Tianrui feel a strong sense of security.
In the last days, there must be great love, but small love must be sacrificed.
For the sake of everyone, I have to sacrifice my family.
However, Li Yu is completely the opposite.
As a vested interest in Li Yu's concept, Ju Tianrui can't say anything against it.
"Contact Lao Xie and the others and see where they are?" Ju Tianrui said to Xiao Jun next to him.
They can't go to the north yet. They have to wait until the first group of people from the north arrive to send helicopters from Oil City to spray liquid nitrogen.
Because the first batch of people to be transported back from the north arrived in a hurry, there was no liquid nitrogen in the helicopter.
If Li Qi and the others came over, there would be heavy fog in Oil City.
However, the helicopters in Oil City all flew to the north to transport people. Due to heavy fog in Oil City, Li Qi and the others were unable to land at all.
Ju Tianrui looked at the clear sky and the sunshine at noon. The sunshine was just right.
His eyes looked a little worried.
Ten minutes later, Xiao Jun hurriedly replied: "They have been leaving for two hours and are expected to arrive at our side in an hour."
"Okay, the headquarters base has tested the feasibility of helicopter liquid nitrogen spraying. After thirty minutes, if it becomes foggy, you can ask Yu Wei and the others to fly the helicopter above the Oil City and spray liquid nitrogen to clear the fog. Wait.
Li Qi and the others are coming."
"Yes." Xiao Jun nodded.
"By the way, regarding liquid nitrogen, you have people rush to produce it." Ju Tianrui reminded.
Xiao Jun frowned and said:
"Our equipment here is limited and cannot compare with the headquarters base. Now we have turned up the maximum horsepower for production, but... if heavy fog comes, if the helicopters in the oil city have to fly to the north, then we will have to give the helicopters over there,
What we can leave here in Oil City...may not be enough..."
Ju Tianrui gritted his teeth and said:
"It's okay. Once the fog hits, immediately light all the oil pits outside the wall!"
