Jia Yang drove Xiao Gu back home, but it was already dark, and Xiao Gu's battery was running low.

The electricity absorbed during the day was enough to support him to return home smoothly, but because he encountered the mutated zombie that turned into a monster, he wasted a lot of electricity trying to shake it off.

There is still one block away from home.

"Can we turn off Xiao Gu's power first and start it again when the sun comes out tomorrow? That way, we can use the remaining electricity to recharge." I suggested.

Jia Yang helplessly put Xiao Gu into standby mode: "We can only do this for now."

We sat around the dining table eating self-heating rice and discussing the monster we encountered at the research institute in the afternoon.

"Is this the third mutation? What is the source of this re-mutation?" I stirred the rice in my bowl, feeling a loss of appetite.

"Could it be because the research institute itself contains a lot of chemicals, and the zombies undergo chemical reactions after coming into contact with these chemicals, leading to mutations?" Jia Yang's rice in the bowl remained untouched. He was initially drooping his head, but after hearing my question, he regained his senses and pondered for a while before responding.

Lin Yan shook his head: "It shouldn't be the reason. Otherwise, after the research institute fell for a month, there wouldn't be just one zombie that mutated three times; there should be many."

"Then what could be the reason? Are their weaknesses the same as regular zombies, just a headshot?"

"In theory, yes. Because even if they mutate, their weakness is still the virus in the central nervous system. They just have stronger combat power than ordinary zombies."

"But it's too big. According to the preliminary analysis data sent back by Xiao Gu, it's 2.3 meters tall and has a sturdy physique like a bodybuilder. After humans turn into zombies, they still retain their original appearance, right? Can this kind of mutation cause their already necrotic body functions and ceased bone growth to develop for the second time? Is that possible?" I felt somewhat incredulous.

"Xu Zi, there have already been enough impossible things since the virus outbreak, and this monster did indeed grow to such a size." Jia Yang sighed, lowered his head, and said softly.

Indeed, there have already been enough impossible things. Things that were once thought to be absolutely impossible are slowly happening. What else in this world is impossible to happen?

I was speechless for a while, stopped talking, and silently took a bite of rice.

"In fact, in a sense, mutation is also a form of evolution. Each zombie mutation is a step towards greater strength... because the secondary bone growth caused by mutation is not an impossible thing. Even ancient civilizations had giants, and giants were also the result of genetic mutations in scientific terms," Lin Yan said.

Actually, it's not that I don't believe, but I don't want to believe.

I have always hoped for the day when humans would eliminate zombies and return to normal society as soon as possible, unwilling to believe the fact that humans seem to be facing increasing difficulties on this path.
