The challenges in the trial grounds had shown Jiang Feng his own shortcomings.
He could not even defeat the projection of Scarlet Female Yaksha, whose cultivation was equal to his own. Naturally, Jiang Feng did not dare challenge Ji Kongling's projection again.
Though he had suffered no real losses, the feeling of being brutally slain was certainly not pleasant.
He left the trial grounds and went to the Scripture Pavilion.
He had to deepen his foundations now.

He only had four thousand years left.
Over those entire eight hundred years, his cultivation had not advanced a single step.
He had initially believed that after digesting all the Blackstone Mountain Range's collected works, he would at least be able to seize the opportunity to comprehend a fifth-level void law, perhaps even a sixth-level void law.
