Zhao Dawei and his team didn't delay, delving deep from the entrance immediately.

However, the voice of Tutu resounded in their earpieces. "Attention, attention! America's CIAS, the Genetically Enhanced Human brigade, has dispatched a total of 120 people. Among them are three SSS-level experts, while the rest are all SS-level experts. However, their current route is the opposite of yours because they are pursuing Zhang Bin. Zhang Bin killed Edward. Now he has fled into a previously undiscovered passage of the Biological Base and is rapidly making his way inside. Accelerate your pace and take this opportunity to infiltrate the central area and obtain the Genetic Enhancement research results you want..."

"Zhang Bin? Pfft..." Zhou Tianyu burst into laughter. "That guy had only reached the Initial Liquid Realm last time we met. Don't tell me he's cultivated to the Golden Core Realm now? He actually managed to kill Edward? And so many other experts? He even drew out America's strongest Genetically Enhanced Human brigade, securing this precious opportunity for us?"

The last time he went to Sanchahe Village to break a formation, he had clashed with Zhang Bin, who had demonstrated formidable power by using it. Therefore, the memory was still fresh in his mind.

"Him? He's just a daredevil," said Master Tianlong. "This time, he usurped the title of World King of Gamblers, earning Edward's ire. Given Edward's character, he would definitely go after Zhang Bin, and Zhang Bin is not the type to take a loss lying down. So, this outcome isn't surprising. However, he is still far from reaching the Golden Core Realm, having merely advanced to the Liquid Phase Middle Stage. He probably relied on treasures from his sect to kill Edward."

"Reaching the Liquid Phase Middle Stage so quickly is quite impressive," Zhou Tianyu responded. "Should we go rescue him, Dawei?"

"All of you must follow orders. Now, hurry up and penetrate the base. The faster we succeed, the safer Zhang Bin will be," Zhao Dawei said sternly.

He was clear-headed. If they sent people to rescue Zhang Bin now, it would be a terrible move. It would waste time, and splitting up would reduce their overall strength. The defenses of the Biotech Base were also formidable. In fact, Zhang Bin himself understood this, which was why he didn't ask Tutu to have them come to his rescue.

Soon, they entered the underground passageway and made their way to the entrance of the first layer of the underground base. Indeed, it was only at this moment that Tutu discovered the underground base had two layers. Even the Americans had only explored and utilized the first layer; they had not yet discovered the second.

Four powerful Genetically Enhanced Humans stood guard at this entrance. But of course, they couldn't withstand an assault from experts like these and were effortlessly assassinated. Their bodies were naturally collected into their Space Rings.

However, the large door before them was shut. The door was formidable, a meter thick. The walls were equally intimidating, forged from a super-hard alloy. Even Zhou Tianyu lacked the ability to infiltrate, as he had not yet mastered Metal Escape. To master Metal Escape, one had to cultivate to the Mid Nascent Soul stage.

Still, such a door naturally couldn't stop super experts like them. If Zhou Tianyu released his Samadhi True Fire, he could melt the door in an instant. But doing so would alert the guards inside, making a vicious battle inevitable.

"Wait here for a moment. The door is controlled by a light brain. I need two minutes to hack it and get the door to open," Tutu said over their earpieces, imitating the voice of Chen Junheng.

"Damn, Hacker Rabbit King Chen Junheng is truly awesome! He can hack the underground base's light brain and make the door open automatically?"

Everyone was utterly shocked, admiration written all over their faces.

"I have lived for 980 years and have never admired anyone. But now, someone worthy of my admiration has appeared, and that is Hacker Rabbit King Chen Junheng," Zhang Hangkui praised.

"With such a remarkable individual in China, our mission will go much more smoothly this time," Zhou Tianyu said, equally in awe.

"Chen Junheng and Zhang Bin are truly the rising stars of China," Master Tianlong added with admiration.

Meanwhile, Zhang Bin was sprinting for his life through a different passage, while Tutu was furiously hacking the base's perimeter systems. Since Zhang Bin had now entered the periphery of the base, Tutu's hacking had become much easier. Otherwise, the distance would have been too great for Tutu to invade the base, which was shielded by some kind of special material.

Finally, Zhang Bin reached the rear entrance of the base. Since the Americans hadn't had time to excavate this far, they naturally hadn't posted any guards here. Otherwise, Zhang Bin certainly would have met a tragic end.

However, he now found himself in a desperate situation. There were no branches in this passage, leaving him with nowhere to hide. Since this location was dozens of kilometers deep underground, his Wall-Piercing Ability would be useless. He couldn't escape with it, as he would only get stuck in the dirt and eventually suffocate to death. Therefore, he had to enter the base as quickly as possible.

The Middle-grade Flying Sword Blood Fang suddenly appeared in his hand, and he slashed viciously at the door.

CLANG...

Sparks flew, leaving only a shallow mark on the door. Breaking through was absolutely impossible. He tried the walls as well, only to find they were made of the same material, which even a Middle-grade Flying Sword couldn't penetrate.

Zhang Bin was out of options and exasperated. Damn it... How can this door be so hard? Tutu, how long will the hack take? When can you get the door open?

"Master, it will take another two minutes," Tutu's voice replied in Zhang Bin's mind.

In fact, Tutu had begun hacking long ago. A successful hack wouldn't just open this door, but also the door up ahead, allowing Zhao Dawei, Zhang Hangkui, Zhou Tianyu, and the others to get inside.

I may not have enough time, Zhang Bin thought grimly. A Fate-Stealing Talisman appeared in his hand, and he slapped it onto his forehead, then waited for the Genetically Enhanced Humans to catch up.

Just a few breaths later, Jack and the other 120 incredibly strong Genetically Enhanced Humans arrived. The passageway here wasn't pitch-black; a bright light emanated from certain special parts of the base's walls. Thus, they could see Zhang Bin very clearly.

Jack let out a terrifying sneer, his body erupting with an intensely violent and murderous aura. The other Genetically Enhanced Humans radiated the same feeling.

Zhang Bin's gaze swept over them, finally resting on three individuals: Jack, Ava, and Sandra. He instinctively felt that these three were the leaders and were all terrifyingly powerful. They seemed comparable to a Nascent Soul Stage Master like Zhou Tianyu.

Of course, the twin sisters Ava and Sandra are truly beautiful, he lamented inwardly. Before their Genetic Enhancement, they must have been powerful Superpower Users and stunning beauties. What a pity.

"Kneel and confess everything, or I will kill you on the spot," Jack commanded, his eyes locked on Zhang Bin as he seethed with killing intent.

His face was filled with contempt, as if Zhang Bin wasn't worth his notice. It was no wonder. Zhang Bin had only reached the Liquid Phase Middle Stage, so any one of them could eliminate him with ease. As an SSS-Class Gene-enhanced Person, Jack was confident he could kill him with a flick of his finger.
