Although the fusion was successful this time, Wang Tao felt a bit frightened afterward.
He had a premonition that with his current strength, he could only fuse one or two more different types of crystal cores before he couldn't continue. Otherwise, it would definitely lead to disaster.
Now he finally understood what that feeling meant.
The first time he fused with a Zombie Core, he hardly felt anything; it was done in the blink of an eye.
When fusing the second type of crystal core, he just felt a bit of heat in his body, but it wasn't uncomfortable, and he felt fine after lying in bed for a while.
But this time, when fusing the third type of crystal core, his body felt very hot, and he was somewhat dizzy, just like having a high fever—in fact, his body temperature really was very high, having reached over 50 degrees Celsius.
If he were to fuse a fourth crystal core, he estimated his body temperature would be even higher. He didn't dare to imagine just how high.
