Duan Qianshan didn't enter the sacred academy, but there was no need to doubt his strength. He was someone arranged by the Heavenly Talisman Realm for the sake of the adjudication battle, and the vast majority of the hundred participants from the Evergreen Alliance, were all at the peak of immortal-foundation. Not only that, each and every one of them were characters who had glimpsed the gate leading to the next realm, able to control a trace of immortal-king might.
Before this, Qin Wentian wasn't acquainted with Duan Qianshan as the Heavenly Talisman Realm was extremely mysterious and they had many disciples. It wasn't strange that there were some characters who were in closed-door seclusion trying to break through to the immortal-king realm back then when the sacred academy appeared.
