To be honest, Zhao Hai's performance in the space was quite good. Some races specialized in cultivation, while others had created a strange path. Their results were quite good. If Zhao Hai used all the power in the space, he wouldn't be at a disadvantage against the ghost cultivators. At the very least, he could protect himself.
Zhao Hai's strength was indeed very strong to face a ghost cultivator who could turn the entire true spirit world upside down. However, he would not do that, because if he did, others would know that he had a space, and it would bring endless disasters to the countless races in the space.
Of course, the most important point was that Zhao Hai realized that this world was not as simple as it seemed. The pyramid-like hierarchy seemed to be deliberately done by someone. If one's strength was not up to the standard, one would not be able to enter the next higher realm.
