As soon as he activated the Nether Hell Furnace Art, the dead bodies inside the furnace started burning wildly. The fire rose to the lightning barrier. But, it didn't affect the barrier instead it collided and remained there.
Slowly, the fire started calming down but at this exact moment, Lan Ming threw the drop of Phoenix Blood into the fire and the fire exploded once again. This time the phoenix's blood kept the fire burning for a long time.
At the same time, the red energy burst out of the flame and reached out to Lan Ming. This energy was not only dense but also filled with intense healing factors. As soon as the energy touched Lan Ming, he touched Guan Xing and Qiu Yu bodies.
With his intense control, he transferred the energy drawing into him to their bodies. Though it took a while for them to absorb since they were not conscious. The energy kept pouring into him for ten minutes and he kept pouring that energy to them for twenty minutes.
