Reverend BA Dao was a cautious person, and he was not sloppy in his handling of things.
The endless means of the northern sword immortal sect had already made him extremely apprehensive. Otherwise, he would have already killed the Great Demon King and snatched the heaven-grade elixir. Why would he have left Li Tian here to act arrogantly?
But now, seeing the Great Demon King swallow the earth-grade foundation-building pill, Reverend BA Dao's pupils shrank.
Even if the Great Demon King advanced to the foundation building realm, he would still be able to crush him. After all, the combat power of the foundation building realm was different. Moreover, the Great Demon King was a fake Foundation establishment cultivator!
But even so, Reverend BA Dao was not willing to take the risk.
Therefore, he chose to attack directly!
