Li Meng lost consciousness before energy pulled him into the pool. A force pulled him deep into the pool, and he began to ingest a considerable amount of energy into his body. Although Li Meng's body wasn't reacting to this phenomenon, his body soon began to take in power and heal itself automatically. The first thing that healed up was his blood tissues and energy channels. They were a prime requirement for his body to be able to heal itself.
Once the energy managed to encapsulate them and help regain their structure, blood and power began to flow throughout his body and kickstarted the self-healing process. Energy penetrated his organs and other tissues and slowly mended them back to their original state. One would observe from the situation that every healed part of Li Meng's body was much more vital than in his previous state.
