It was during the final secret contest at Ru Lin Academy when he and Qu Muzhi encountered a master from the Yu Yuan Sect, the Sect Master of the Xiu Sect, a very formidable woman.
She relied on her strong spiritual power to fish several ghosts from him.
Luckily, he had many magic artifacts, plus Qu Muzhi as a competent ally. The two put forth every effort, with Qu Muzhi gravely injured and near death, finally managing to take down the opponent.
"If it wasn't for running into you, this freak, any Fierce Level Apostle would surely have ended up dead." Sheng Yanlin sighed deeply, possibly feeling sorry for that Xiu Sect Master.
On this, Yang Xiao thought of the spy that was slain by Ru Lin Academy's Old Clan Leader, Yang Qianhe. According to their conversation, that spy was also dispatched by Yiling Academy.
