Yang Ming's inference wasn't wrong. Tian Dongguang was indeed the second young master of Donghai's Tian Family, the powerful Tian Family.
Tian Dongguang and his brother had been taught by their family since they were young. When they grew up, they had to take over the business of the Tian Family and became the new generation of managers. The mission of the Tian Family was to assist the Sun Family.
Tian Dongguang's eldest brother wasn't very interested in the things about the underworld, but the second young master, Tian Dongguang, was very interested in fighting ever since he was young. But, he was more forthright as he wasn't as smart as his eldest brother.
