Longhun and Ren Haotian had died.
Soon, Yang Tao'er and the others received the news, and they were worried that if Su Zhanze found out Ye Chen hadn't gone mad with magic, he would likely try every possible means to kill him. Judging by Su Zhanze's action of killing Longhun and Ren Haotian, it was indeed possible for him to do so. Su Zhanze, with his strong vindictive nature, feared Ye Chen might threaten him in the future, just as he had feared Longhun would.
Therefore, after discussing with Li Mo and others, they unanimously agreed that the best way to protect Ye Chen and make Su Zhanze feel completely unthreatened was to spread the news that Ye Chen had lost his mind due to magic.
In this way, Su Zhanze would not consider Ye Chen a threat.
Once the plan was agreed upon, Li Mo had his subordinates take people and spread the news that Ye Chen had gone mad with magic, and they also deliberately said that many had died at Ye Chen's hands without knowing his whereabouts.
