Chang Ying was stunned on the spot.

You have to know that since the disaster struck, the monster has been growing and becoming more and more powerful. From moving slowly at the beginning, to running in the daytime, it finally settled at a speed between walking and running.

They are even more terrifying at night. Their agility exceeds that of ordinary people. Except for those well-trained guards and soldiers, ordinary people would be in danger of death if they encountered those monsters at night.

Wei Xiyin remained calm upon hearing this.

Because Chu Yu had experimented before and found that high temperature can only have an inhibitory effect. Maybe it is in the inhibitory stage now, but the guards mistakenly think it is degenerating.

She said, "Tell me in detail first."

The guards did not dare to hide anything and immediately reported what they had discovered.

"My subordinates and I weren't sure at first. There were no villages or towns along the route we were taking, and there were very few zombies nearby. Only a few stray ones occasionally wandered the road."

"After we left Fuyang, some zombies followed the scent and chased us. We then discovered that they seemed to be unable to run all of a sudden."

During the day, the speed of zombies is fixed between walking and running. When there are no living people around, they move slowly and look like people taking a walk. But once they smell the scent of living people, they will instantly become excited, roaring and suddenly speeding up, running towards the crowd.

However, the guards discovered that since some time ago, these zombies suddenly could not run anymore.

Even though it smelled a living person nearby, it did not increase its speed, but walked towards the person.

Wei Xiyin tapped her fingers and said cautiously, "Don't jump to conclusions yet. It seems that some changes have occurred in the growth of the zombies. Let's talk about it when we get back."

With such an obvious mutation, the research institute will definitely discover something.
