Now that his remaining weaknesses are patched up, he begins to attempt a breakthrough.
This breakthrough is not as strenuous as imagined; as soon as he attempts it, the aura around him abruptly heightens, and then the five Cave Heaven Cores begin to absorb energy.
All the energy within the Cave Heaven channels into the Cave Heaven Core, making the Core more solid.
A large amount of energy enters the Cave Heaven Core and then flows out again.
The outgoing energy is already of the Middle Stage Great Power level, far stronger than before.
After the Cave Heaven evolves to the Middle Stage Great Power, it feeds some energy back to the physical body, augmenting it once more.
However, the enhancement to the physical body is not very noticeable, primarily because his body was already exceptionally robust.
"Phew!" Li Shiming exhaled, awakening from the changes brought by his promotion.
