The patient with the shell disease screamed, convulsed a few times, and then lost consciousness.

The remaining three patients with crustacean disease still had bloodshot eyes.

"kill!"

They roared and howled as they attacked Colin again.

However, their wounds slowed them down considerably.

Colin's steel needles were incredibly sharp, and he quickly found an opportunity to pierce their bodies through cracks in their carapaces, killing them instantly.

Colin waved his hand, and the steel needles flew back and landed in his hand.

Colin adjusted his glasses slightly and chuckled as he explained to Lu Ning, "These are just third-tier infected individuals, but they seem to be defensively specialized, so they're quite resilient."

Lu Ning nodded slightly, then looked in Lin Xiao's direction.

Colin looked over as well.

The battle between Lin Xiao and the muscle giant was extremely destructive; the entire second floor was almost completely destroyed, and in some areas the floor was even broken, revealing the space on the first floor.

Colin frowned slightly and said, "This patient has probably reached the fifth level. If it was caused by the Corruption Incense, then the harm caused by this incense is probably greater than we imagined."

Upon hearing this, Wang Qiwen immediately looked at Colin: "By the way, Vice Captain, have you found the incense?"

Colin shook his head: "And you guys?"

“We didn’t have any either. We had just gone up to the third floor when we saw a large number of patients gathered together. This patient with muscle disease was surrounded by them.”

"The patients are all gathered together? Why?" Colin asked, puzzled.

"I don't know either," Wang Qiwen shrugged. "Anyway, as soon as we went up there, these infected people came at us."

Just as they were talking, the person with the muscle disease suddenly let out a roar. The next moment, the muscles on his body writhed violently, and his already huge body grew another half meter in size.

He rushed in front of Lin Xiao in an instant and threw a powerful punch.

Lin Xiao blocked with both arms, his expression grave.

The next moment, he was slammed into the floor and fell to the first floor. With a loud bang, cracks spread across the floor, and the entire second floor collapsed.

Lu Ning and the others also fell to the first floor.

"Captain!" Wang Qiwen called out nervously.

Colin adjusted his glasses and said, "The captain won't die from this."

As if to prove this point, a deep black light flashed.

The next moment, a figure rushed out from the boulder ruins and charged straight at the muscular giant.

The muscular giant was immediately sent flying, traveling more than ten meters away.

At this moment, Lin Xiao's clothes were torn, his body had reached a height of more than three meters, and his skin had turned red, with wisps of steam seemingly rising from his skin.

He was also holding a long black stick in his hand.

A ferocious silver snake coiled around the surface of the long staff. The silver snake seemed to be alive, swimming around the staff and even wrapping around Lin Xiao's wrist.

As Lin Xiao picked up the Serpent Staff, his aura put immense pressure on Lu Ning.

Wang Qiwen, standing nearby, asked in shock, "What is this? Why does that stick make me feel so uncomfortable?"
