When Han Sen heard what Old Xu said, he was shocked.
The Angel Gene fluid the Zhao family had created was not their original creation, after all. It had been based on that vial of liquid.
Angel Gene could never find out what the exact components of the solution were, so it was a bit of an enigma. Roughly, Angel Gene only understood ten percent of the fluid in its entirety.
Humans could not use the liquid itself. That much was certain. Consumption of the liquid would result in the consumer exploding, even if they were a strong surpasser.
When Han Sen asked where the liquid came from, Old Xu told him it came from the grave of a shura king.
"Shura kings can never catch a break from graverobbers, it seems. First, it was the Falsified-Sky Sutra, and now this," Han Sen mused over the elucidations he was receiving.
Han Sen was happy he never used the liquid. Had he done so, he would have most assuredly died.
