The Dragon King is released from prison

This underground base is well prepared.

And Qi Tian was also well prepared.

"Brother, what should we do next?"

In front of the alloy gate, Bai Chi was wearing a gas mask. He was not in a hurry at all and even wore special heat-insulating clothing.

"There's a vent here, how about we let some poisonous smoke in for them?"

"It's useless." Qi Tian shook his head. "They are well prepared. Gas masks and other things are essential items."

"They have to watch the screen anyway." Bai Chi said, "Put some poisonous smoke in there to block their vision. It will disgust them anyway."

"That's right." Qi Tian nodded, "By the way, add some stink bombs or something, and then have Bao Xiong bring down some Molotov cocktails and throw them into the ventilation ducts to warm them up."

After a while, a burly violent bear wearing a gas mask came down pulling a cart full of things.

"Damn it!" Bai Chi couldn't help but swear, "You don't even know how to take some precautions. Aren't you afraid of being detonated by the high temperature?"

Bao Xiong scratched his head: "I couldn't help myself when I wanted to do something. I didn't think too much about it. This gave me the same excitement as when I was a kid and secretly smashed other people's windows."

Qi Tian opened the ventilation duct and said, "Throw it in!"

Baoxiong and Bai Chi excitedly threw the things in the car into the ventilation duct.

Stink bomb.

Poison gas bomb.

Incendiary bomb.

A lot of things were thrown in, and soon thick black smoke was seen coming out of the ventilation duct. The black smoke was mixed with blue and dark green, and it looked like it was extremely poisonous.

"And these."

Baoxiong pulled out a few blowers from the bottom of the cart.

"You look quite simple-minded, but when it comes to this kind of thing, you are really thorough."

Bai Chi praised and stuffed the blower into every vent, turning the air volume to maximum.

The air currents from all directions converged together, bringing with them the thick smoke with a highly toxic and foul smell. The stench was so strong that even people wearing gas masks could not withstand it. Even Qi Tian, ​​who had undergone special training by Old Man Jiang, felt nauseous.

All the ventilation vents have backflow from blowers, causing the poisonous smoke to flow in only one direction, which is the control room inside!

In just a few seconds, the control room was filled with poisonous smoke, and some computer operators had no experience in wearing gas masks.

Normally, it would take a well-trained soldier three seconds to take out a gas mask from his backpack and put it on, but these people didn't even put it on for thirty seconds. They didn't even adjust the elastic bands of the gas masks before they fell down.

As for the rest, even those who wore gas masks had their vision blocked by the poisonous smoke. Not to mention operating the computer, they couldn't even see the screen clearly. They could only see fuzzy lights, and the stench stimulated their nerves all the time. Some people couldn't help it and vomited directly, but they were wearing gas masks.

The entire control room was in chaos.

The middle-aged man looked at the poisonous smoke coming out of the ventilation duct, cursed "shameless" and communicated on the internal radio.

"Block the ventilation duct! Open a hole in the secret door on the side and find a way to get the poisonous smoke out!"

Several armed men immediately went to do it, however, as soon as they arrived in front of the ventilation duct, they saw a large amount of water pouring out of the ventilation duct.

There was more than one vent, and all of a sudden, water was pouring down from all directions.

Unfortunately, this water is not clean at all, there is a foul smell in it!

"asshole!"

The people in the control room cursed loudly. They brought steel plates, suppressed the nausea, groped for their way in the thick poisonous smoke, and blocked all the vents bit by bit.

After doing all this, more than an hour had passed. The entire control room was filled with the stench, the water had spread to the calves, and all the machines had stopped working because they were not properly protected.

"All the ventilation holes were sealed, leaving only one small opening, and there was not enough oxygen for everyone to use."

"I've already contacted the people outside, you bastard! Why hasn't their support arrived yet?!"

The middle-aged man cursed loudly. At this moment, he had no idea that an armed force had entered the Free City and took control of the city. The support he wanted would not arrive in a short time.

"Mark! Keep an eye on Mark! Even if he dies here, Mark must complete his mission! We have disclosed all the information to him this time. If we cannot achieve the results we want, our losses will be unbearable!"

The middle-aged man drew the pistol from his waist and walked towards the control room.

In front of the largest screen in the control room, a figure can be vaguely seen sitting in the light and shadow. The thick poisonous smoke does not seem to affect him. His fingers are tapping on the keyboard quickly, and he is also switching the screen back and forth at a very fast speed.

The middle-aged man walked behind the other person, put a gun to the back of his head with one hand, and took out a headset with the other hand and hung it on his ear.

"how long will it take?"

"It will take at least five hours at the fastest." Mark answered calmly.

"Impossible." The middle-aged man ordered forcefully, "You only have two hours at most. I need you to find all the coordinates within two hours, otherwise I will smash your head."

Mark's hands, which were rapidly typing on the keyboard, suddenly stopped and leaned back in his chair, saying in a relaxed tone, "Why don't you just kill me, so I can save myself the trouble."

"You..." The middle-aged man was angry, but it was obvious that he was also being controlled by Mark, "Is there any way to speed up?"

"Give me the authorization." Mark said, "As far as I know, you have the largest storage capacity for nuclear warheads. If you give me the coordinates, it will reduce my workload and unnecessary investigations. It will at least shorten the time by 50%. I hope to finish these within two hours."

"Do you think that's possible?"

"That's up to you." Mark spread his hands. "That's the fact. No matter how powerful an optical computer is, it's not God. Its computing speed is always limited."

The middle-aged man pointed the gun at Mark.

Mark seemed to have given up and refused to move.

After a few minutes, the middle-aged man compromised: "You have to do what you say, otherwise, you will die an ugly death."

The middle-aged man walked aside and made a phone call. Soon, he came behind Mark and pointed a gun at Mark's head.

The middle-aged man couldn't see the crazy smile on Mark's face hidden behind the gas mask.

Outside the control room.

"Boss, do you have any dirty tricks?" Bai Chi looked at the sewage that could no longer be poured in, "They won't be able to get out for a while like this."

"Ask Baoxiong, he will definitely have it."

Bai Chi looked at Bao Xiong.

"I……"

"Killer Whale just sent a message!" The fox's voice suddenly rang out over Qi Tian and his companions' internal radio, "He detected that the small country east of Free City has initiated an armed counterattack procedure!"
