For the next six to seven days, Xu Tui immersed himself in studying the Primordial Spirit after breaking through to the quasi-planetary realm and the traditional culture of the Huaxia Daoism.
This was especially so since Xu Tui's current mind power was powerful. It brought about an extremely powerful memory and reading speed. This research progress was very shocking. Including his accumulation in college and his recent hard work, Xu Tui had basically finished reading all the ancient Huaxia books that Ah Huang could search for.
Xu Tui had studied most of this cute and stupid Primordial Spirit, Little Xu. His most obvious change after breaking through to the quasi-planetary realm was that his mind power had more than doubled.
Just because his mind power had more than doubled did not mean that his strength had also doubled. However, it was still a lot.
