In the cave, Greg Jensen finally realized something was wrong.
He had intended to absorb all the Yin Sha and consolidate his realm in passing, but as he absorbed it, the surrounding Yin Sha not only didn't decrease, but it gradually increased.
He abruptly opened his eyes and looked ahead, only to see that the black crevice between the two stone doors had grown a bit larger than before.
Whoosh!
A gust of Yin wind blew through, and a large amount of Yin Sha poured out from the gap in the doors.
Greg Jensen's expression became solemn, he didn't know what was inside the stone doors, but something that could produce so much Yin Sha was definitely not simple.
He gathered his True Qi, readying the Falling Thunder Technique. If anything weird appeared, he would strike it with lightning first.
Among the techniques he currently mastered, the Falling Thunder Technique was the most powerful, and it was also the most effective against dark forces.
