Zheng Hai.
The personal disciple of the Tyrannical Sea Legend, Yu Zhihui. His talent was a water-element strengthening talent, a very common talent. The reason why he was taken in as a disciple by the Tyrannical Sea Legend, a titled expert, was because Zheng Hai's contracted Blue Salamander accidentally mutated into the Leviathan race after swallowing unknown resources due to a cultivation mistake.
This experience could be said to be identical to the Tyrannical Sea Legend. In the early years of the Tyrannical Sea Legend, it was only an ordinary fishing youth. His initial pet was also the Blue Salamander of a low-level transcendent race. It only knew one bubble skill.
However, it was precisely because this Blue Salamander accidentally swallowed an unknown resource and completed its mutation evolution that it obtained the super racial skill Infinite Devour. This allowed the Tyrannical Sea Legend to directly rise and become a super expert at the top of Dong Huang.
