The moment he saw the spider robots, a strong sense of unease surged in Yu Yifeng's heart. He instinctively dodged to the side.

"Pop, pop, pop," a series of bullets flew past the edge of his clothes, and a trace of blood seeped out from his arm. Fortunately, he dodged quickly, and it was just a superficial wound, nothing serious.

The shooting speed of these spheres was astonishing. The small holes under their electronic eyes were the muzzles. As soon as a flash of fire was seen, a series of bullets burst out.

These were spider robots, the most advanced war weapons, fully intelligent weapons developed by the Israelis. It was unknown how Calvin had obtained the control authority.

Yu Yifeng quickly slipped into a nearby room, picked up his gun, and started shooting back at these robots. However, as soon as he showed his head, he felt bullets raining towards him.

"They can detect the infrared light of the human body, have extremely high shooting accuracy, and are good at close - combat. The metal legs under them are like blades, capable of easily slitting a person's throat."

A series of relevant information emerged in Yu Yifeng's mind. This was what had been taught in the military academy. Fortunately, these robots were small in size, had limited ammunition capacity, and were not resistant to attacks. They were only highly lethal when swarming. With only two of them, he should be able to handle it!

He immediately took out a grenade from his waist and threw it out. With a "boom", the grenade exploded, billowing thick smoke. This building was constructed with titanium - steel and lunar soil, and it was so hard that it didn't even budge under such an impact.

He didn't know if the grenade had hit. The shooting speed of the two robots immediately slowed down. Taking this opportunity, Yu Yifeng suddenly leaped up, rolled on the ground for several meters, and then started shooting frantically in one direction.

The high - temperature from the grenade explosion could temporarily block the infrared vision, creating an opportunity that only lasted a few seconds. Only someone as bold and skilled as him would dare to jump out and shoot at this moment. A series of crackling metal impacts were heard, and it seemed that he had hit them!

Another series of bullets came, but they had already lost their accuracy. Yu Yifeng fired several more shots until there was no more movement from the robots.

After a while, he walked over quietly. The thick smoke was gradually dissipating. One spider robot was severely damaged and completely turned into a pile of scrap metal. The barrel of the other one was already crooked, one of its two electronic eyes was knocked off, and it lay on its back on the ground, motionless.

"Fortunately, there aren't many of these robots. Otherwise..." If there were hundreds or thousands of them, even he wouldn't be able to survive.

Looking forward, Calvin was running forward at full speed. He was almost at the end of the corridor and even had time to make a face at Yu Yifeng!

Just as Yu Yifeng was about to chase after him, suddenly, his scalp tingled, and goosebumps rose all over his body. He heard a sound similar to that of a metal spring. Looking back, he saw that the robot lying on the ground had "come back to life". Its two front claws were like two flying knives, shooting towards him at lightning speed!

An ordinary person surely couldn't have avoided this fatal attack. The distance between them was only a dozen meters, and the speed of the flying knives was close to 100 meters per second, reaching him almost instantaneously. The nerve - reaction limit of an ordinary person is 0.1 seconds. Before they could react, they would be stabbed, and there would be no chance of survival!

But Yu Yifeng was different. His nerve - reaction speed was ten times that of an ordinary person, and his athletic ability was also far beyond that of ordinary people. He was a superhuman!

His heart tightened, and hormones in his body were secreted rapidly. His pupils dilated slightly, and with his keen dynamic vision, he caught the trajectory of the flying knives. Then, his body suddenly leaned backward, making an incredible evasive move. The two flying knives whistled past his head.

However, the situation didn't end there. The robot then bounced up and pounced on Yu Yifeng. Its body was spinning rapidly like a chainsaw. If he were hit, it would mean certain death or serious injury!

At this moment, Yu Yifeng's entire body was lying at a 90 - degree angle facing the sky. How could he dodge? He gritted his teeth and let out a loud shout, "Hey!" Then, he forcefully kicked with his legs, flipping his whole body up and performing a beautiful backflip!

In an instant, the spider robot just passed under him!

"Wow!" Calvin shouted from the opposite side. He seemed stunned, but his feet didn't slow down. He had already reached an elevator entrance. He turned around, pressed a few buttons, and when the elevator door opened, he made a "good - bye" gesture to Yu Yifeng and then quickly got in.

Yu Yifeng was extremely anxious. His figure flashed, and he dodged several more attacks. He pointed his gun at the spider robot and pulled the trigger several times. There were a few "click, click" sounds, and it turned out that he had just run out of bullets!

He reacted very quickly. With a wave of his arm, he smashed the gun barrel onto the electronic eye of the spider robot, pushing it out like a ball. Then, he smashed it three more times in succession, "Bang! Bang! Bang!" The entire gunstock was completely deformed, and finally, the spider robot lay on the ground, motionless.

Yu Yifeng quickly ran to the elevator entrance, but the elevator door had completely closed. Only a number was flashing, 166... 165... 164... He looked at the other elevators. Damn it, they were all parked on the first floor!

He punched the elevator door, making a loud "clang" sound and creating a dent. Then, he dialed the headset beside his ear.

"Hello, Lao Xu, can you hear me? This is Yu Yifeng!"

"Captain, it's me. What's the situation?"

"I don't know what Calvin is up to. He's playing hide - and - seek with me... Now, I order you to enter the lobby on the first floor. Almost all the hostages are gathered there, and so are the rebels. The situation is rather strange. Don't attack for now. Try to communicate with them... Be extremely careful." As he spoke, Yu Yifeng rushed towards the stairwell.

"There may be more than fifty remote - controlled bombs there. You must defuse them immediately. There's a map on the 44th floor. Send someone to check it!" Yu Yifeng almost roared, "You have five minutes, no, less than four minutes. Do you understand?"

"Four minutes... Understood!"

Yu Yifeng had full trust in his comrades. They were all excellent young men, the most elite force of all mankind. The most urgent task now was to catch Calvin! If they couldn't catch him, this mentally ill person might really detonate the bombs!

As he went down each floor, he glanced at the number in the elevator shaft. 59... 58... 57. The speed at which he was going downstairs was almost as fast as the elevator, no, even a bit faster. But Yu Yifeng still had to spare some attention to be vigilant against Calvin. No one knew what traps he might set on the way.

5... 4... 3... 2. Finally, the elevator Calvin was in stopped. A dozen seconds later, Yu Yifeng also arrived on the second floor. But at this time, there was no one around the elevator. Calvin had disappeared.

However, this couldn't stump Yu Yifeng. Methods like judging footprints and fingerprints were too cumbersome. He was a superhuman. The simplest way was - to smell!

He closed his eyes and sniffed slightly. A large number of odor molecules were like a bright light in the dark, clearly indicating Calvin's direction. "Calvin, you can't escape!"

This was the superhuman. As powerful as a lion or a tiger, as agile as a cheetah, with vision as sharp as a warhawk, and a sense of smell as keen as a hunting dog... a superhuman who surpassed humans in all aspects!
