Gu Nian, who was still wearing a protective suit, stepped forward, rinsed the thing that fell out of the zombie's brain with water through the plastic sheet, and handed it to Lin Chen: "Mr. Lin, do you know what this is?"
Zombies have stones in their brains?!
That thing seemed to be a translucent shell with a colorless liquid inside.
Lin Chen glanced at the thing and shook his head: "I don't know what it is. But in apocalyptic novels, zombies usually evolve crystal nuclei. Maybe it's this thing."
"Is this... the result of zombie evolution?"
Gu Nian frowned, feeling extremely frightened just thinking about it!
If we reach the later stage of the game, will this island be filled with zombies that are flexible and will not die unless their crystal cores are dropped?
If such zombies evolve to a higher level, what terrible monsters will appear.
"Are we... still going to find the control room as planned?" Gu Nian asked.
Before Lin Chen had time to answer, footsteps similar to those from before were heard in the corridor again.
Moreover, this time, the footsteps were much more rapid and chaotic than before!
Another zombie is coming, and not just one!
Three zombies arrived one after another.
Because the door of the research room is only one meter wide, the two running in front got into an argument because they were trying to enter the door, blocking the third zombie from the door.
After the previous battle, Gu Nian and Lin Chen already knew the weaknesses of this evolved zombie.
The two of them seized the opportunity of the zombies' internal strife and cooperated tacitly to knock the three zombies to the ground. As expected, they discovered a substance that was suspected of being a crystal nucleus from their brains.
Lin Chen handed all the cleaned crystal nuclei to Gu Nian: "Put these things away, maybe they will be useful."
"These guys... must have been attracted by the gunfire during our battle." Gu Nian looked at the zombie corpses lying on the ground and patted his chest with lingering fear: "Let's leave here quickly and go to the control room!"
God knows how many zombies there are here, and whether there is anything more ferocious than a zombie with a translucent crystal core in its brain.
"good."
The two walked out of the research room.
"Ouch!" Gu Nian accidentally stepped on something and made a squeak, which startled her.
She looked down and realized that it was a sign covered in blood, which seemed to be the layout of the research building of the HSBC Institute of Biology.
She and Lin Chen looked at each other, preparing to clean the blood stains on it and find the monitoring room as soon as possible.
At this moment, the two people's expressions changed drastically.
The sound of overlapping footsteps comes from far to near!
A large number of zombies in white coats ran down from the upstairs!
"Let's go! Go to the basement first!" Lin Chen grabbed Gu Nian, held her hand, and ran towards the basement.
Gu Nian actually wanted to refuse this suggestion.
She didn't know why, but the basement didn't feel very good to her.
Intuitively, she always felt that it was dangerous there.
But now there is no choice.
If you stay here any longer, you will have to face those zombies in white coats!
When facing the zombies outside, even a newbie like Gu Nian can kill a kid with one shot.
But the zombies inside this research institute are not as easy to deal with as the zombies outside.
