An hour later, everyone gathered in a small bungalow beside the Central Building. The last team also returned on time, with no one missing. This made Yu Yifeng secretly breathe a sigh of relief.

"Report, Captain! A total of 322 rioters who took the opportunity to create chaos have been killed, over two hundred have been captured, and more than three thousand hostages have been rescued." After finishing counting the data, Xu Yunjin stepped forward to report.

"Well done!" Yu Yifeng nodded and praised.

Now there was still the toughest nut to crack left, that is, the criminal gang led by Calvin. To be honest, the combat effectiveness of the other criminals was pitifully low, just at the level of civilian riots. But the gang led by Calvin was different. They were organized and disciplined, and they should be treated as opponents of the same level. One couldn't be too cautious.

Seeing that everyone had already finished resting, Yu Yifeng didn't hesitate any longer. "Get ready to move out! Shen Jie, get ready for sniping. The rest of you, spread out and stay on alert. Be ready to provide cover at any time!"

The Central Building was the largest surface building in the Lunar Base. Its floor area was as large as that of thirty football fields. The top part of it even reached the circular glass cover.

It could be said that this building was actually a pillar supporting the circular glass cover.

Yu Yifeng walked at the front of the team, with a tense expression on his face and became more and more vigilant in his heart. He wasn't fighting alone. There were over twenty comrades beside him, and the lives of tens of thousands of people were at stake behind him. He couldn't afford to be careless at all!

Along the way, it was somewhat thrilling but without major mishaps. There wasn't the feeling of being targeted by a sniper. He was a battle-tested warrior with an instinctive intuition for danger, that is, a powerful sixth sense, which had been verified in countless battles in the past.

Moving forward, they found that the main door was closed and couldn't be pushed open. This door was made of carbon steel, which was over ten centimeters thick. It was impossible to break it open by brute force.

"Something's not right. There are neither patrolmen nor guards." Yu Yifeng was full of doubts and couldn't figure out what Calvin and his gang were up to.

Their actions were quite suspicious. Logically speaking, since the Earth had been destroyed, there was no one to negotiate with. Whom could they threaten with the hostages in their hands?

Were they trying to seize the control of the entire base? Or were they attempting to destroy all of humanity? Yu Yifeng frowned. All these were possible scenarios, after all, Calvin... was a mentally unstable person!

Five years ago, when he was still on the Earth, Calvin had been a very successful entrepreneur, wealthy and powerful, and he even had the opportunity to get access to the secret of "Perfect Element"! At that time, those who could get access to the secret of "Perfect Element" were either noble aristocrats, major politicians, or top tycoons. It could be said that they were all from wealthy and noble families.

However, no one had expected that such a successful person would inexplicably engage in cult-related activities, which was really puzzling... It was later confirmed after his arrest that Calvin did suffer from a mental illness.

It was said that this mental illness was deeply hidden and had a latent tendency of self-destruction, but it was usually hard to detect. There were also rumors that Calvin's case was a miscarriage of justice and was the result of the conflict among several political forces. There were hidden circumstances behind it.

But in any case, since they were now on opposing sides, they should be resolutely eliminated.

Yu Yifeng led the team to search around again and found several glass windows, a ventilation opening, and two side doors. The ventilation opening was too small for an adult to crawl through, so it was ruled out first. And breaking the glass windows would make a loud noise and easily alert the enemies.

Finally, Yu Yifeng chose one of the side doors.

The whole team had already spread out completely. Everyone was extremely careful and tried not to make any noise. Their rifles were all pointed at the side door. In case of any unexpected situation, they would immediately launch a fierce barrage of gunfire.

"Xiao Zhang!" Yu Yifeng waved his hand forward and made a gesture.

This was a capable man who was just 1.7 meters tall. Usually, he was honest and didn't talk much. His name was Zhang Jun. He had an ordinary appearance but was a mechanical expert, proficient in all kinds of machinery. Cars, airplanes, tanks and so on were all within his competence. Of course, unlocking a door was just a piece of cake for him.

Zhang Jun tiptoed forward, took out a bunch of special tools, briefly examined the door, and fiddled with it for about two minutes. Then the lock was opened.

At that very moment, Zhang Jun suddenly felt something was wrong. He took a quick step back, covered his head tightly with both hands and shouted loudly, "Quick..."

With a loud "boom", before he could finish his words, the door exploded directly! In an instant, Zhang Jun at the front was engulfed by the explosion, and Yu Yifeng, who was closer, was also blown away and flew dozens of meters away. He felt dizzy, his ears were ringing, and everything in front of his eyes was pitch black.

"Oh no, Calvin has discovered us!" Yu Yifeng instinctively thought in a daze. He tried desperately to stand up but found that his body seemed to be falling apart and wouldn't listen to him at all. It wasn't paralysis but a mild concussion that made him temporarily lose his mobility.

The team members around also reacted very quickly. They started shooting immediately, "Bang, bang, bang", without caring whether there were enemies inside the door or not, and carried out fire suppression first.

"Stop! There's no one inside!" After a while, Deputy Captain Xu Yunjin shouted.

This kind of explosion... This familiar scene... Yu Yifeng felt as if he had gone back to five years ago. His temples were throbbing. Five years ago, when they were arresting Calvin, several comrades died because they fell into traps. Now the same situation had happened again! Before they even saw Calvin himself, they had already lost a team member!

"Captain! How are you?" Xu Yunjin quickly stepped forward and helped Yu Yifeng up.

"It's okay. Just some superficial wounds. I'm just a bit exhausted. How's Zhang Jun?"

Zhang Jun was lying on the ground, almost motionless, with blood all over his two arms. Fortunately, he reacted quickly and protected his head with both hands at the moment of the explosion.

Zhao Yao had the closest relationship with Zhang Jun. He threw himself in front of Zhang Jun and burst into tears. This was a comrade who had gone through life and death with him many times. Was he gone just like that?

This was a comrade who had laughed together, played around together, and carried out missions together. Was it really over like this...

Zhao Yao was the newest member of the team and was experiencing the cruelty of war for the first time. While crying, he helped Zhang Jun tidy up his body. Suddenly, his face lit up with joy. For a moment, he didn't know whether to cry or laugh. He wiped his face and immediately took out a syringe and injected it into Zhang Jun's body, shouting loudly, "He's not dead! He's still alive!"

It turned out that Zhang Jun was also wearing a thick layer of lead blocks, weighing at least one or two hundred kilograms. Thanks to this, these lead blocks blocked most of the damage. Now he was just in a coma due to a concussion and excessive blood loss.

"You guys, take him back and give him a blood transfusion first. He's blood type B. Don't make a mistake!" Yu Yifeng managed to stand up with difficulty. He found that his nostrils were bleeding and quickly wiped them with his hand.

There was no need for several people. Zhao Yao picked him up with one hand. "I'll go! I can do it alone." Everyone in their team knew some medical skills. As long as a person wasn't dead, they could handle injuries like this.
