Time passed.
Shang just kept breathing heavily as he became weaker and weaker.
A lot of his grit and willpower had already vanished, and he felt like dying wouldn't be such a bad idea anymore.
However, Shang also recognized that this was the effect of Death Mana entering his mind.
There was no Death Mana around Shang, but Shang's mind was still slowly being filled with Death Mana.
That was just natural.
This was how Death Mana worked.
At some point, the body and mind would start to produce Death Mana at a slow rate, and the Death Mana would slowly overtake the body.
First came the sickness. Old people would become ill many more times than younger people.
