In the area of the Huangzhuang defense line, it has been raining acid for five hours.

The raindrops, with their turbid yellow color, fell from the sky, dripping on the rocks and the earth, and it was a small white foam burning hole, and the whole earth had been severely corroded.

The ground was foaming with acid water flowing slowly, the earth was covered with a layer of highly concentrated sulfuric acid vapor, and the Great Rift Valley in front of the battle line, the valley floor had formed a winding acid river, flowing eastward.

The corrosive effect of the acid on the metal is so strong that after standing outside for a few minutes, the heavy aluminum firearm will be unusable.

However, after three days of research, Jiayu mastered the multi-layer composite casting technology, a layer of nano-material coating surface, a layer of source carbon nanotube alloy material support structure, and then nested multi-layer buffer material to form the cheapest light armor steel, so that the mechanical armor produced by Tianjin Machinery Factory can ignore the high concentration of acidic substances in the air.

In just three days, the Tianjin Machinery Factory frantically assembled 1,200 fully automatic defense turrets, each of which more than doubled the firepower of the original turrets.

In three days, Tianjin Machinery Factory took out all the inventory, increased all the production capacity, and became a rioter.

At the same time, the surface armor of the Juque has also been modified by Jiayu, and the original chrome brushed surface of the wind has been completely dismantled and replaced with multi-layer nested composite materials, which has reduced the total weight of the body by 30% and increased the strength by 17%!

Now, the Juque is in an unmanned state, suspended at high altitude, and Fat Bai is personally in charge, fighting for air supremacy in the Huangzhuang defense line.

A combat team composed of more than 100 high-end scientific and technological talents operates an emergency individual weapon platform system, a single weapon platform, composed of 125 mm tank guns, two rocket launchers, multi-barreled Gatling cannons, ultra-long-range snipers and other weapons, all of which are installed in a mess on everyone's single power armor.

They were like more than a hundred small tanks, quietly waiting from their positions.

…………

Yang Fan hired Jiayu as the first military instructor and commander-in-chief of the Machinery Factory Corps, and the old man Sun Desheng was afraid that something would go wrong, so he sent a company commander of the original Tianjin garrison in the adjudicator team, which was a high-achieving student with the highest military education among the Tianjin adjudicators.

When the company commander received the task, the mechanical corps had already driven to the Huangzhuang defense line, and he was sent by Academician Lu to the defense line dozens of kilometers away.

The company commander was angry in his heart, and when he saw the equipment of the machinery factory, his eyes were green, and he shouted, "Such a good weapon, it is absolutely a waste to use it for you, and I will transport it back, and the layman will disband it on the spot!" ”

The mechanical legion, three days ago, was all workers in the factory, and they hadn't even fought a fierce beast, so they had to face the elite field division of the capital Chejia, which was indeed a bit difficult for a strong man.

But the company commander scolded them for nothing, and Jiayu was also angry in his heart, thinking, "Although my soldiers have been practicing for three days, they can't even do a single order to prohibit them, but this is my business, why are you here to make trouble?" ”

He ignored this external commander, and the young company commander was angry, "War, it's not a game, the enemy comes and shoots, these wastes are absolutely shitting, it's a pity that these turrets are wasted like this, and you, are you the commander-in-chief?" Fart! Hurry up and move things back for you, slow down, you will be killed! ”

Jiayu didn't say a word of nonsense, only one word popped out, "Get out!" ”

The staff of the Armed Forces Control Committee hurriedly came up to say a few soft words, but the junior officer broke out, he felt that he was a top student studying at the Military Academy, can you be a civilian? Will you shoot? Haven't you just played a real-time strategy game for a few days and just wanted to waste money?

The officer brazenly pulled out his gun, "What did you say?" Do you dare to make a bet, 100-meter shooting target, 50-meter pistol as you choose, whoever wins has the final say, do you dare! ”

Jiayu glanced at it, took out the super large revolver with the holster, and opened fire with a bang, the little officer was flustered, feeling that the gun in his hand was missing, and the people around him let out a sharp inhalation.

His adjudicator uniform didn't change the slightest, but the five bullets almost grazed his skin and flew out, and all of them here were microscopic pinnacles, or god-level masters, and they could see the trajectory of the bullets clearly. One bullet smashed the pistol to pieces, and each fragment was hit with another bullet......

Then, he grabbed an automatic rifle and fired indiscriminately into the sky behind him.

At the same time, Jiayu raised the huge Hellboy revolver, and the high-speed bullets were fired indiscriminately into the sky.

The rifle was finished with a shuttle of bullets, and the high-ranking people in the command headquarters did not know what was happening, and it didn't take long for a small soldier to walk in with a large plate of shrapnel.

The officer found that each rifle bullet was pierced by an armor-piercing bullet like a slender needle!

He had a little bit of a face on his face, which was much more fierce than throwing a target and shooting...... Of course, Jiayu is also a trick, the automatic rifle fires a 20 mm caliber slow bullet, only more than 700 meters per second, and then fires a high-speed armor-piercing bullet, which is launched by electromagnetic use, with a speed of more than 1500 meters per second, in fact, the bullet did not fly far and was hit by Jiayu one by one.

"You're good at shooting, but command, it's not good to shoot well......"

Jiayu frowned, his mood was a little irritable.

"You go back, you don't need to command here."

What else did the officer say, but he was kicked out by Yang Fan.

Jiayu was indeed a little irritable, and a day ago, the Watchman satellite system had spotted that the two elite divisions of the Che family were moving frequently and assembling towards the middle of the rift.

But a day later, due to the weather, a large number of sulfide clouds appeared in the capital, Hebei and Tianjin, and the clouds were too thick to block the video surveillance of the Watchman satellite system, and the infrared exploration equipment almost completely failed.

He knew that a team of elite soldiers like the Che family had countless camouflage methods, which could evade the detection of satellites without knowing it, and the first hand to know oneself and the other disappeared.

The situation on the battlefield was out of Jiayu's control, and he thought, "Or?" Just throw a nuclear bomb and blow up the car's house, save trouble. ”

The training time of the fighters is too short, and the estimation of three-dimensional warfare is also somewhat insufficient, they do not know that the enemy can use modern tactics such as transport planes, armed helicopters, and other flying equipment to airdrop on a large scale, and make large-distance detours to wrap more than 100 soldiers of the mechanical legion in dumplings.

The Tianjin Machinery Factory has few people, so it can only guard the pass, one man is the pass, and ten thousand people are not open, so the final result can only be the annihilation of the whole army.

In this case, Jiayu also has no two-wing front arrangement, Yang Fan is the vanguard of the left wing, and Liu Moxi is the general of the right wing, taking into account the essence of modern warfare and cold weapon warfare.

No matter which direction the enemy is coming from, just fight.

Jiayu originally wanted to stay in Tianjin for a few days, and after waiting for Liu Moxi's injuries to improve, he took the earth dog to the capital, gathered the northern base evolutionaries who supported the battle in the capital, and everyone went home together.

Now he felt like he was sinking deeper and deeper, and he couldn't escape.

…………

The war was about to break out, and in front of the Great Rift Valley of the Huangzhuang Defense Line, the long-range radar of the Tianjin Machinery Factory finally scanned the enemy's traces.

It's just that they found that there was only one one who came to fight?

Is this funny? Or is this person too fierce to be a thousand?

One of the fighters in the front line, who did not have much organizational discipline, secretly opened the safety and aimed at a figure the size of dust and gravel in the far distance opposite the rift.

He wanted to shoot a shot, three days of training, he wanted to die, the training intensity was so intense, he hadn't had time to shoot yet, he had an urge to make history.

Someone actually opened the insurance without permission?

Jiayu suddenly felt that a burst of anger pierced the top of his head, what the officer said just now was indeed right, any army with such a soldier who did not obey orders, the commander would be furious.

He checked it casually, turned on the intercom device and shouted, "Liao Kaixuan!" If you dare to shoot, Lao Tzu will collapse you now! ”

This bold young man is the second stunned man who once organized dozens of workers to hide behind the wall, intending to ambush the elite army.

Liao Kaixuan has never fought, but he feels extremely good about himself, he always feels that he is a peerless master, he never wants to listen to orders, and he always feels that the world suppresses him......

He also became Jiayu's biggest headache, and Jiayu tried to expel him from the team several times, but in the end he still didn't succeed.

Liao Kaixuan heard Jiayu's roar, hesitated for a few seconds, but still released the trigger of the power armor and closed the insurance.

"It's the best time for me to make a difference, I missed ......"

…………

The Che family sent a person, what does this mean? Tianjin Machinery Factory is a little confused.

The figure walked very slowly, and on a few occasions almost fell, adjusting its pace before continuing on.

The distance between the two places is more than ten kilometers, and it is impossible to distinguish the details of the characters' faces with high-powered telescopes, but Jiayu feels a hint of familiarity.

He yelled in the communication channel, "Don't shoot anyone, I'll go and see!" ”

The plasma rocket booster system of the Xuanwu 1 power armor was activated, and it swept over the Great Rift Valley at high speed, jumped to the opposite side of the rift, and after jumping a few times on the rock wall, it climbed over the mountain beam and lost its trace in the fog.

After a long time, Jiayu's call sounded, "Yang Fan, hurry up and find the iron and prepare to save people!" ”

He pulled back a man from far away.

When they got closer, the workers of the Mechanized Corps gathered around, and a middle-aged man shouted, "Factory director? Director Yao? ”

Jin Yong's fellow friends will be the third child, the director of Tianjin Machinery Factory, Yao Demon is back!

…………

Yao Demon was injured all over his body, and the moment he saw Jiayu, he suddenly relaxed and fell unconscious.

The bones of his body are twisted together, it should be the result of random growth of bones after many tortures, Yao Demon is like a twisted monster, I don't know how to walk down the capital to Tianjin for more than 200 kilometers!

Except for Yao Demon, the capital did not send a single soldier.

After the conflict between Tianjin and the capital broke out, Yang Fan immediately sent someone to inform Yao You, who was doing business in the capital, but it was too late at this time. They thought that Yao Demon had encountered an accident, but they didn't expect that when the war was about to break out, Yao Demon came back.
