Misty Immortal Valley

After successfully refining the third Dragon Emperor Sarira, Yi Yun rested for some time before choosing a day to prepare to swallow it.

The moment the Dragon Emperor Sarira entered his mouth, Yi Yun immediately felt a clear stream slide down his throat and enter his dantian. But just then, a terrifying heat surged from his dantian, as though it had transformed into an erupting volcano. The blood coursing through his meridians became boiling lava, and even his skin suddenly turned scarlet. If this continued, he seemed certain to be burned into ashes from the inside out.

Yi Yun remained calm. He immediately circulated the Dragon Emperor Art, refining the medicinal power within his body. At the same time, the surrounding Yuan Qi surged madly toward him, even forming a Yuan Qi vortex beside him.

Yi Yun's body was like a giant whale drinking water, crazily absorbing Yuan Qi. Gradually, the Yuan Qi vortex almost became solid, with the Yuan Qi inside condensing into droplets. Each drop contained an ocean of Yuan Qi.

Yet all this Yuan Qi was continuously absorbed through every pore of Yi Yun's body. The blood in his meridians surged like a mighty river, and waves of dragon roars came from within him, as though a colossal dragon were awakening here. Even the concealment formation could not completely hide the disturbance.

For a time, everyone in the entire town heard a rumbling boom, though no one could tell where it was coming from. At first, the people were panic-stricken, but after the town's Grand Elder, whose cultivation was the highest at the Kaiyuan Realm, searched everywhere and found nothing, they gradually settled down.

As time passed, the people of the town grew used to it. Aside from being somewhat noisy, the sound brought them no danger.
