Mo Sheng was livid. Even if he had no talent, he still had his pride. No matter how he was insulted and constantly compared to Mo Jiu, he never harbored hatred against his shidi and chose to be angry at the people who spoke nonsense instead.
In fact, he was happy that Mo Jiu was talented. That way, elder Mo wouldn't lose face too much but what he'd seen that day had crushed him. He couldn't even report them because he had no proof and that move would be quite dumb either ways. What would he have said?
He confronted the both of them and Mo Jiu, with his low EQ, had told Mo Sheng that he'd done nothing wrong. Shen Mianmian didn't love him and they weren't dao partners yet so she could be with whoever she chose.
Angrily, Mo Sheng turned against Mo Jiu and troubled both him and Shen Mianmian whichever way he could. A lot of people saw this and hated Mo Sheng even more but he didn't care. How was it his fault?!
