Tang Wulin’s Blood

Tang Wuln said, "Alright then. How much do you want?"

Ling Zichen said, "Not much. Ten drops is enough."

"Hmm. Now?"

"Now!"

It was not an easy feat to draw Tang Wulin's blood because his body was already close to being the Leakproof Golden Body. Under ordinary circumstances, it was almost impossible to leave a wound on him unless it was done with a divine weapon. This was even more the case when he was protected by the Golden Dragon Body.

Ten minutes later, Ling Zichen's eyes were no longer red. She held a small test tube in her hand and looked at the ten drops of blood in it, gaping at it in excitement. 

He had used the Golden Dragon Spear to prick a wound on his hand and squeezed out the blood.
