The two engaged in hand-to-hand combat.
The face of this Taiyi Golden Immortal changed dramatically; he had already realized that this person's physical body was no weaker than that of a Taiyi Golden Immortal.
Moreover, the most critical factor was that the mysterious black-and-white millstone suspended in the air was gradually grinding away his life force!
In contrast, Li An was acquiring a large amount of life force from the black-and-white millstone.
One depleting, the other replenishing!
...
Three hours later.
Li An sat panting in front of his cave dwelling, opening the storage rings of this Taiyi Golden Immortal one by one.
This battle was extremely difficult and indeed involved a certain degree of risk. The reason Li An did it was mainly to test his combat power.
The results were very satisfactory to him!
"The black-and-white millstone, if it truly matures, could indeed dominate life and death!"
