Ao Yun felt that he had thought of a good idea. In that case, he only needed to summon the lich and get it to go out and cause trouble to attract attention and help him obtain half an hour of time for his sacrificial formation.
However, there was a problem now.
He knew Moreton, but he did not know the lich.
What if the other party came out and killed him?
This was not impossible. Instead, it was very likely.
After thinking for a moment, Ao Yun thought of a good idea.
He had heard Moreton say that the amount of blood essence was related to the strength of the lich summoned.
He only needed to make sure he didn't give the lich too much blood essence. It would be fine as long as that lich was not too powerful.
At that time, he could at least resist the other party.
With the summoning formation activated, the aura he had sensed previously would probably quickly rush over. At that time, the lich's attention would be attracted.
