What exactly is it?

Li Tian was on the verge of going crazy. From his skin to his hair, from his hair to his saliva, and even a small piece of his flesh, he was cut off by the ghost king.

This was because the results of the experiment were out. It was true that the serum couldn't cure the poison. This meant that the antidote wasn't the serum in Li Tian's body but something else.

There was only one solution left, and that was the kidney.

The ghost king wanted to operate on Li Tian and take out some things from his kidney for experiments.

The operation this time would require an incision, and the recovery time would definitely be very long.

The ghost king said to wait for another half a day. Since they were already at this stage, they didn't care about a little more time. They wanted Li Tian to rest and recover first.
