"There it is!"
After a long time, Tang Hao finally found something.
The ancient book in his hand introduced the ten ancient Buddhas. It recorded their great achievements, how many demons they had subdued, and how many enemies of Buddhism they had suppressed.
It was mentioned that the general trend thunderclap Buddha had once subdued many demons and suppressed them.

During the suppression, it was said that the general trend thunderclap Buddha had used a powerful Buddhist treasure and a large formation at the same time. He had used dozens of drops of blood essence to maintain the formation.
Although it had been a long time, there was still a slight possibility that a few drops had been left behind.
