Liu Sheng is the son of Jiang Chen, one of the three great generals of the Temple of the Gods. He lay low and secretly grew stronger beside the Dragon King for sixteen years. He won over the Dragon King’s only daughter and earned the trust of the Dragon King’s mother-in-law, then tricked all of the Dragon King’s trusted followers into becoming his own capable subordinates. With his awakened martial arts panel, he advanced:
From Tai Chi Fist to Eight Trigrams Palm,
from the Supreme Art, Kunpeng, to the fusion martial technique Supreme Art, Nine Suns Fierce Phoenix.
He built up his own Temple of the Gods...
The God of War of Huaxia is nothing! I, Liu Sheng, am the supreme ruler of this age!
