The Tang San in Douluo Continent comics hadn't turned dark. He had always been a character full of controversy and challenges. In the comic, Tang San was a genius Spirit Master with many spirit rings and formidable spirit power, but his personality was gentle and kind, not good at fighting. After experiencing many difficulties and challenges, Tang San gradually grew and learned more battle techniques and strategies, and at the same time also gradually understood himself and others. He was no longer a pure genius Spirit Master but a Spirit Master with deep thinking and a sense of responsibility. In the latest comic plot Tang San had already displayed his leadership and strategic thinking, becoming an even more mature and powerful character.
On Douluo Continent, Xiao Wu's Sacrifice for Tang San was chapter 15.
