Golden Body Fluid

If one rubs the Golden Body Fluid all over their body before using a Source Fluid, they become impervious to swords and guns, and the basic quality of their body increases substantially.

It is very difficult for armor-piercing rounds to pierce the skin of someone who has applied Golden Body Fluid.

Luo Yunyang had been able to tell that the golden body fluid was actually a drop of blood.

A drop of blood of unknown origin.
