Peerless Tang Sect: I've Gone Dark

Why did Tang San become a god? Is it because of the innate full soul power he has achieved through practicing Xuantian Kung since he was a child? Is it based on his so-called unique skills from his previous life? Unchanged for ten thousand years? Is it based on the moves he made after becoming a god? Why did Tang San become a god? Why control luck? Divide the divine throne? Why should he regard the Douluo plane as his own backyard? Who will open the curtain of ten thousand years, and who will come to see Douluo who cannot be subdued? Who knew that both divine and animal natures are human?
