Huitiandan

"It's finally started!"

Mu Yun gave a low voice, lifted his palm, and snorted: "Start!"

With a ticking, blood flowed from Mu Yun's fingertips, and then, the ticking sound kept ringing.

The blood from Mu Yun's fingertips followed the purple flame into the Fengtian Cauldron.

Suddenly, in the Fengtianding, a belching voice sounded, and Mu Yun's fingertips were ticking blood faster and faster.

Gradually, Mu Yun's face began to become ruddy.

Soon after, the blood on Mu Yun's face gradually disappeared.

Instead, he was extremely sickly pale.

It's just that Mu Yun didn't stop, but the blood ticked faster and faster.

"Mu Yun, you can stop!"

Seeing Mu Yun's body began to tremble, Gan Jingyu began to remind him.

But Mu Yun ignored this.

He continued to release his own essence and blood, merging bit by bit on the pill in Fengtianding.

Gradually, Mu Yun's body began to shake, and his lips trembled.

"Mu Yun, you can't continue!"
