To jump in troubled waters

Yin Rentian shivered while glaring at Yin Fu hatefully. He could not believe that Yin Fu dared to choke him like this, he nearly suffocated him until he lost his breath! He would have died of suffocation if Yin Fu had not let go of his neck. 

"I am not going to let this matter go so easily," Yin Rentian glared at Yin Fu who was walking away while muttering angrily. He was going to make sure that Yin Fu was suspended for harming a fellow student. This was one of the rules of the academy after all, no student was allowed to harm his peer or classmate. 

Since Yin Fu dared to make a move on him, then he could not blame him for kicking him out of the academy. 

He then turned to look at his underlings and scolded the one on the right. "What are you doing? Help me up!" He was the closest to him and yet he was not even helping him up! 

Was he blind?
