669 He Feng Yang’s scheme

This cave was as large as a plaza; blood colored light filled the cave along with a dense bloody odor. In the center of the cave, a round hole had been dug out, inside of which blood gurgled and emitted hot air.

Fang Zheng took a deep breath before taking off his clothes in a familiar fashion, when naked he then entered the blood pool, immediately taking large gaping breaths due to the scalding blood.

He soon adapted to the temperature of the blood and stood still at the center of the blood pool. The blood pool reached up to his waist, revealing his chest and most of his arms.

"Begin. Do it one by one, don't be anxious. First is iron blood Gu." Lord Sky Crane reminded.

Fang Zheng slowly closed his eyes and activated iron blood Gu as instructed.

Immediately, the Gu worm's power started transforming his blood. His red blood began to darken and become denser, the blood flow also became extremely slow.
