"Oops, I can't hold it back." Such a thought flashed through Chu Dajiang's mind, and then a soft "poof" sound came out of his hips, and those bodyguards who had put their hands on the holsters pinched their noses with disgust.

"Puff puff puff ......" The serial fart sound resounded in the narrow corridor non-stop, even if he wore a mask, Chu Dajiang's face was still flushed. Running away with his legs tightened, he couldn't even bear to look at the bodyguards in the hallway, skimmed his face, raised his eyelids and looked at the ceiling.

After running for more than 100 meters, Chu Dajiang finally ran to the safety zone, and the gas in his stomach was almost cleaned at this time. Chu Dajiang fanned the wind in front of his nose. His sense of smell is much stronger than that of a human, and he didn't feel anything when he was running in a hurry just now, but now that his spirit is relaxed, the farts that remain in the corridor are almost stinking him.

"Hey, you're in the safe zone so quickly? I didn't see that you were quite talented! "The monitor in this piece has already become Lu Renjia's eyes, and as soon as Chu Dajiang arrived, Lu Renjia found out.

"That's it." Chu Dajiang's face was not red, and his heart was not beating.

"Did you find that exhaust port on your left foot? Remove it and burrow into the vents. Lu Renjia instructed in the headphones.

"Drill ventilation ducts, you can come up with such an old plan?" Chu Dajiang asked in a daze.

"Don't worry, listen to me." Chu Dajiang seemed to still hear the sound of Lu Renjia slapping his chest over there.

Hearing that Lu Renjia's tone was so sure, Chu Dajiang moved suspiciously and demolished the steel fence of the exhaust port.

"Okay, after you get into the ventilation duct, you will enter a signal blank area, I can't contact it, the road map is stored in your watch, good luck." Lu Renjia said over there.

"Got it." Chu Dajiang pulled the miniature earphones out of the cracks in his ears, twisted his ass and squeezed them into the vents, and after getting into them completely, he didn't forget to put the fence back up.

After drilling into the black ventilation ducts, Chu Dajiang crawled with difficulty in the narrow pipes, and some of the ventilation ducts were directly exposed. Whenever Chu Dajiang climbed to these places, he was so frightened that he didn't even dare to get out of the atmosphere, and he could even hear the crackling sound of the keyboard in the office below, the sound of running water in the toilet, and the squeaks of various unknown live test animals in the real room.

Suddenly, Chu Dajiang stopped, his ears moved, and he heard a rustling noise, which was not from under the ventilation pipe, but from the front.

Did you run into a peer? Chu Dajiang's muscles tensed, and he stared at the corner of the ventilation duct in front of him.

A glove stretched out from the corner, Chu Dajiang's pupils shrank, his index finger raised, and an invisible knife qi continued to expand and contract like a poisonous snake's letter, ready to move.

But there was only one glove that crawled out, and there was nothing behind it. Chu Dajiang's eyes widened in panic, and in the narrow pipe closed on all sides, this glove rustled towards him.

A faint smell entered his nose, Chu Dajiang reached out and patted it like lightning, and at that moment, Chu Dajiang noticed that the weight of the gloves was not light.

The glove slammed into the ventilation duct, and a gray figure fell out of it.

Zombie rats!? Chu Dajiang made the first move, and without waiting for the gray figure to stand firm, the knife qi that was already ready to shoot out.

Flutter! A pool of brown-black dirty blood splashed on the wall of the ventilation pipe, Chu Dajiang picked up half of the corpse, scarlet eyes, saw-like teeth, and deformed sharp claws that exceeded the fingertips a few centimeters, what else could it be except for a zombie rat that could grow into this terrible appearance?

How can there be zombie rats here? And whose glove is it? Chu Dajiang was suspicious, threw down the corpse of the zombie rat, and took the gloves to his eyes to look at them carefully.

The gloves are made of tough rhinoceros leather, but they are no match for the sharp teeth of zombie rats, and they are riddled with bites. The glove has a broken mark: IMF. Chu Dajiang vaguely remembered that An Qi had said that this was the name of the Impossible Task Team, and he clearly remembered the admiration on An Qi's face when he talked about this organization.

The Ministry of Biochemistry, the zombie rats, the ventilation pipes, and the scum that is likely to be gnawed by the zombie rats are not left, Chu Dajiang connected these elements, and couldn't help but shudder, could it be that these zombie rats were specially stocked in the ventilation ducts by the Ministry of Biochemistry?

Thinking of this, Chu Dajiang suddenly felt that the empty ventilation duct had become dangerous, and he seemed to be under a river full of piranhas. Chu Dajiang wanted to ask Lu Renjia for clarification, but there was no signal during this time.

Damn, if I really run into a swarm of zombie rats, and then it's a big deal to cut the ventilation ducts, I don't believe that the top brass of the Biochemistry Department are willing to let the zombie rats eat all their men. After making up his mind, Chu Dajiang put away his gloves.

However, before continuing to set off, Chu Dajiang cautiously tried the hardness of the ventilation duct. The army provided by Lu Renjia. The knife could not leave a hole in it. However, Chu Dajiang's sword qi could easily make a hole in it. Only then did he relent, and continued to climb along the ventilation duct.

Hey? Why didn't I talk about zombie rats all the way, could it be that I was too unlucky before, and now Jitai is here? Chu Dajiang arrived at his destination smoothly, the outer wall of the twenty-first district.

And he only encountered a zombie rat along the way, which made Chu Dajiang himself feel incredible.

As soon as he got out of the vent and put on the miniature headphones, Lu Renjia's voice chattered from the other end of the headphones:

"Although the entire 21st District is only 300 square meters, the 21st Area is wrapped in two extremely solid defensive lines, and the defense against nuclear strikes is only a piece of cake. The first steel gate weighed several tons, and the second steel gate was called the Star Wars Gate...... Obediently, it's even tighter than the protection of our MI9 headquarters......"

"Okay, you don't need to introduce so much, I'm not here for sightseeing, you just tell me how to get in." Chu Dajiang impatiently interrupted Lu Renjia's chatter.

"There's no way, the security system here is too advanced, I'm afraid I'll be discovered as soon as I invade, at most control a few cameras, just control the wind for you, this time you have to rely on your own brute force to get in." Lu Renjia said.

No way, then you are still talking nonsense, Chu Dajiang said in his heart, and walked to the steel door that didn't look good on the outside. Chu Dajiang stretched out his hand and touched the steel door, it was cold for a while, and he knocked on his fingers again, it was completely solid, and there should be no alarm device in it.

The thickness of this steel door is not greater than its height, Chu Dajiang took a few steps back solemnly, looked at the steel door that was nearly three meters high, and suddenly with a kick, the rushing and rolling knife waves appeared in the narrow corridor out of thin air, and all rushed towards the steel door under Chu Dajiang's control.

"Boom ......" Chu Dajiang began to worry about the sound insulation effect of the Ministry of Biochemistry, and after a piercing sound of maddening metal twisting, Chu Dajiang put down the ears covering his hands and froze.

This was the first time that Chu Dajiang had found something that the sword wave could not cut with one blow. Although the quality of the steel door is far from reaching the level that can block the knife qi, the steel door wins in quantity. Chu Dajiang looked at the steel cave in front of him, which was more than four meters deep, and couldn't help but swallow his saliva.

The thickness of the steel door was completely beyond his expectations, if this steel door was square, it would have been broken by Chu Dajiang by now. The killing range of the Blade Wave was about ten meters, and here, the invincible Blade Wave advanced less than five meters in the solid steel before its momentum declined.

The corners of Chu Dajiang's mouth twitched, rubbed his sore thigh muscles, and kicked out a wave of knives fiercely. The steel was moaning, and after it subsided, Chu Dajiang only glanced at it and couldn't help but close his eyes.

This steel cavern must be at least eight meters long, right? However, the steel door had not been penetrated, and the metal dust scattered on the ground had already overflowed Chu Dajiang's shoes.

"Lu ~ Ren ~ Jia, can you tell me how thick this steel door is?" Chu Dajiang's voice was trembling when he spoke, half because he was excited, and half because he was tired from using the knife wave continuously for a short time.

"I don't know, but I can give you a few numbers, and you can do the math yourself. Area 21 is only 300 square meters if you only count the internal area, and if you include the external protective layer, it is about 1,500 square meters. Lu Renjia replied.

It's still not good, Chu Dajiang is silent, the difference between inside and outside is more than 1,000 square meters, all of them are lumps of steel! The mere thought of that number makes people desperate.

Lu Renjia seemed to know what Chu Dajiang was thinking, and comforted: "The situation is not as bad as you imagined, otherwise wouldn't we have killed ourselves?" There is a distance between the first layer and the second layer, which is hollow. ”

"You give me a rest first." Chu Dajiang was moved by what he said, after all, hope was in front of him, and he didn't want to give up halfway.

After resting for a while, Chu Dajiang pulled his feet out of the metal powder all over the ground with a little difficulty. The metal powder is no better than the sawdust, the density is placed there, and a thick layer of powder is pressed against the soles of the feet like a heavy concrete boulder.

Whew~ Chu Dajiang exhaled a breath of turbidity, and the metal chips that were blown floated. After he moved his hands and feet, he tried to pop out a few knife qi, and after cutting a few deep openings in the steel door, he changed his left foot, lifted it up and swept out a wave of knives that rolled like a sea of clouds, and slashed at the steel door.

Hearing only a piercing but crisp sound, the steel door was finally penetrated, and Chu Dajiang's eyes suddenly opened up. He sat in the steel cave with a happy ass, tired and out of strength.

It's just that when he saw the so-called Star Wars Gate on the opposite side through the big hole in the steel gate, the joy between his eyebrows gradually converged, and his worried eyebrows twisted into twists.

At this time, Lu Renjia's voice sounded at the right time: "If we work harder, we will succeed!"
