"What the hell, no, what the hell are you guys..."

'Snap.'

'Snap.'

Before the other party could continue questioning, Ren Ying, Xiaolei, and Han Shengjun acted instantly, snapping the necks of the three in front of them, taking them down immediately.

Then the group of four returned to the truck where Li Kuo was waiting and awaited Xiaofan's arrival.

Once Xiaofan arrived, the entire research facility would become a purgatory.

Zhu Fan had already issued a kill order; everyone except internal members was to die here.

Cui Yuan and Wan Jiayuan, both battle-hardened veterans, calmly entered the research facility, killing their way step by step without causing a fuss.

The people inside the research facility had no idea Zhu Fan intended for them to die here, continuing their research wholeheartedly...

But the moment of realization was inevitable; as the killings increased, the people in the research facility began to panic and flee. The sound of explosions soon followed.

These explosions were not set by Han Shengjun and his group but by Cui Yuan and his group, who were killing and blasting their way through. By dawn, this place had to turn into ruins.

The chaos in the research facility immediately caught the attention of the Federation Bureau, who sent a large number of experts hoping to acquire what they desired amid the chaos.

Xiaofan stealthily exited the research facility and regrouped with Li San and the others.

"Hey, where's Ruyu?" Li San's first question upon seeing Xiaofan was about his woman.

"I told the three of them to wait halfway. Even the Federation Bureau members have rushed into the research facility." Xiaofan looked calmly at the chaotic research facility, his brow furrowed; this slaughter was indeed cruel. Although not many inside the research facility were good people, they were still living beings, not even given a chance to change.

Thinking this, Xiaofan sighed inwardly. How could he be any different? Standing here watching them die under the knife without being able to do anything.

"Kuo, blow it up."

If someone had to be the evil one in the end, let him be the executioner.

"Okay."

After receiving Xiaofan's order, Li Kuo lightly pressed the button in front of him.

'Boom.'

'Boom boom boom.'

A violent explosion sounded. Even Xiaofan and the others, standing a kilometer away, were shaken by the intense heatwave.

"Caterpillar, Ren Ying, you two head over immediately. You don't need to fight, just shout loudly. Surely, there are survivors from this explosion. You should shout that Zhu Fan is preparing to escape with the research data; he betrayed everyone."

"Understood."

To prevent Zhu Fan's escape, just six people alone couldn't possibly hold off all members inside Red Butterfly for five hours. All Xiaofan could do was to try his best to get more people to stop Zhu Fan from escaping.

Indeed, Zhu Fan already had that data in hand; although incomplete, with it, it wouldn't take long to redevelop. Once he finds some authorities in this field, talents, it can definitely be redeveloped.

"Everyone run! The boss wants to kill us all! He's been holding the data and planning to escape! Run quickly!"

"Run, everyone, run."

Amid the ruins, very few survived. Xiaofan had them shout to let the hidden Federation Bureau people hear. With their capability, they should've long guessed Zhu Fan's secret base location.

'Whoosh.'

Just as Li San was shouting, a dangerous aura suddenly came from behind. Startled, he dodged swiftly.

"It's you? Caterpillar?" Cui Yuan asked in surprise after seeing Li San's face.

"Oh, you recognize me. Truly skilled, not even the explosion killed you."

"Did you do it? No, it should be the Black Mantis?"

"It's too late to know. However, since you weren't killed by the blast earlier, I'll send you on your way now."

At this point, Cui Yuan was battered and bruised from the explosion. If he hadn't locked himself in a closed room to avoid the fiercest wave of the bombing, he'd likely be among the corpses now.

"What's really going on? Did the boss order you to blow us up too?"

"Want to know? Ask Zhu Fan yourself."

"No more talking, kill him quickly," Xiaofan, noticing Cui Yuan was still alive, immediately urged Li San to act.

"Alright." With that, Li San's figure flashed, revealing his full strength, and he charged at Cui Yuan with a sharp step.

'Whoosh.'

'Oops.'

Another ambush came, causing Li San to hurriedly withdraw his steps and retreat to the side.

"Black Mantis truly harbors ill intent," Wan Jiayuan said, surprised by the ambush, glaring at Li San.

"Why has your ambush regressed so much that you couldn't even kill him?" Cui Yuan asked, smirking.

"That kid's no ordinary one. If he hadn't been disoriented by the explosion earlier, he'd already be dead." Wan Jiayuan replied disdainfully.

"Though I really don't want to cooperate with you, it seems we must kill this kid now and immediately inform the boss of Black Mantis's identity."

"Less talking, I'll go first, you follow," Wan Jiayuan, with a flick of his foot, instantly charged towards Li San.

'Whoosh.'

'Bang.'

In a blink, Li San crossed his arms over his chest, not taking the two seriously at all.

And looking at Wan Jiayuan, who had just charged over, slowly getting up from the ground, with a serious face looking at the person who kicked him down just now. It was close; if he hadn't reacted a bit faster, that kick would've been deadly or at least severely injuring.

"See, that's a real ambush. Hey, Ren Ying, your ambush skills have regressed, haven't they? You couldn't kill him?" Li San mimicked Cui Yuan's tone, teasingly.

"Yeah, what a pity, was so close to killing him," Ren Ying replied honestly.

"Damn, you're no fun," Li San grumbled.

"It's true, he did dodge it just now," Ren Ying admitted with lingering fear.

"Li San, stop fooling around. They may be heads of a sect; deal with them quickly, we have other matters to attend to."

"Got it." Ren Ying nodded, acknowledging.

"Who are you? Who's directing you? Black Mantis? Where is he?" Cui Yuan, noticing the identical earpieces on both, immediately guessed something.

"If you can beat me, I'll tell you."

With that, Li San charged first, with Ren Ying following.

Cui Yuan and Wan Jiayuan initially didn't take the two seriously, but after experiencing their terrifying speed again, they grew increasingly cautious.
