Su Xing was stunned at the sight.
These were not a thousand Grandmaster-level experts, but a thousand Heavenly King-level experts!
The Dragon Spirit Pills and Origin Martial Pills that Su Xing painstakingly developed before had only increased the number of Heavenly King-level experts in the Great Xia Country by a few hundred.
But he hadn't expected the effect of the Rebirth Pill to be so incredible!
The Rebirth Pill was purely aimed at power-type martial artists, helping them enhance their strength.
Although there would be a side effect of decreased rationality for a few months, it would be restored within a year at most.
This efficiency in improving strength could only be described as astonishing!
If Su Xing was willing to continuously refine the Rebirth Pill, it wouldn't be an issue to increase the number of Heavenly King-level experts by a thousand each year.
"Moreover, this is made using the flesh essence of a Demon King..."
