"I must find a way to enhance my strength!"
The sudden display of strength by figures such as Buddha terrified Jiang Chen, making him realize that his preparation wasn't as adequate as he initially thought.
Perhaps, he won't be able to resist Buddha and the others.
It was precisely this reason that Jiang Chen was so desperate to enhance his strength. Why resort to schemes and tricks? It was simply because he wasn't strong enough.
If only his strength was enough, there would be no need for schemes and tricks, he could just force his way through. If people like Buddha didn't submit, he would just have to beat them until they did.
In the end, strength was what mattered in the Prehistoric World.
As for how to enhance his strength, Jiang Chen already had a plan in mind. In the short term, his realm could not be elevated.
Hence, to enhance his strength, he could only tackle it from another angle - like the Great Wish Technique.
