There was no problem with the creation of the bio-brain. Don't forget, Zhao Hai was in his interspace. In this interspace, he was God. He could make anything. The bio-suit itself had a finished product, so there was no problem in making it.
Zhao Hai quickly created the biological brain and asked Laura and the others to communicate with it using their spiritual power. At the same time, he also imprinted their soul marks into the brain. This way, the biological brain would belong to them.
After Laura and the others obtained the biological brain, they immediately felt the benefits of the biological brain. They felt that their thoughts were clearer. Some things that they couldn't figure out before were figured out almost instantly. This feeling was great.
