Hearing the State Preceptor's words, Jiang Hao maintained his silence.
The other party always seemed to say similar things.
It appeared that once again, they wanted him to reveal himself.
However, the State Preceptor leaned back in his seat and said:
"I have investigated for a long time, experimented for a long time, and finally, through various means, arrived at a conclusion.
"Over thousands of years, I have somewhat understood the function of the Ancient Yin-Yang Millstone.
"Of course, only a part."
The State Preceptor looked at Jiang Hao and said, "You must also be curious why it is Tian Liu, and not Tianwu or someone else.
"Additionally, you must have been to more than just one era, right?"
Jiang Hao was silent, but greatly surprised inwardly.
The other party seemed to have truly discovered something.
How exactly the Ancient Yin-Yang Millstone allowed him to reach various eras was indeed unknown to him.
Why it was Tian Liu, he was also uncertain.
