From the looks of it, the biological brain had evolved into a hairy ball. Zhao Hai was very confused. He did not know what this thing could do.
Zhao Hai used his own mental energy to try and make contact with the furball. With this contact, Zhao Hai immediately felt as if he had another brain. He felt as if his brain had suddenly become bigger.
He had shared everything he knew with the brain. He could now control and direct the brain as he pleased. It could be said that although the brain was not in the same body as him, their thoughts were connected. The brain was a part of Zhao Hai's body.
This feeling was really amazing. A person's brain could actually expand. Not only did the brain expand easily, but the detailed dimension was also clearer, and the speed of thinking was faster.
