章 145: I'm Good At Digging

"The vaccine... is still under development.

"We've only developed a rudimentary version of the vaccine, which has a small probability of turning ordinary zombies back to normal people.

"We have no way of dealing with Mutated Zombies yet,"

Liu Shiyao lowered her head and said.

The Director nodded, having seemingly expected that answer.

After all, he didn't have much hope to begin with.

"By the way, how did you guys get down here?

"Did you have the authority to use the elevator?"

The Director suddenly asked.

"Deputy Director Qian was the one who let us down,"

Liu Shiyao replied.

"Qian Feng!

"That guy..."

The zombie director gritted his teeth. His eyes turned cold instantly, and he exuded a murderous aura.

Tang Tang immediately stood in front of Liu Shiyao to protect her.

"What's wrong with Deputy Director Qian?"

Liu Shiyao was stunned.
