Ling Han tried his best, but he couldn't figure out anything.
The Great Emperor killing formation was far beyond his current cultivation level, because even Saints could only stare at it helplessly.
Ling Han felt that it was a pity. He did not insist to learn the complete Great Emperor killing formation, but only needed to learn a corner of it. That would be enough to kill Venerate Tier elites and threaten Saints, right? Just like the Heavenly Dao Flames in his Primal Chaos Extreme Lightning Tower.
So be it if he couldn't learn it. As he worked hard on liquefying the alchemy pool, he cultivated the four newly obtained nine-star high-level energies, as well as the Icy Killing Celestial Finger. This was the Imperial Technique, and when he advanced into the True Self Tier, it could unleash a great might.
However, he couldn't advance or retreat now, so what was the point of him being stuck here?
