Peculiar Poison; Severe Injury

All of a sudden…

"Oh heavens… What is going on?" Wu Tian exclaimed.

Wu Fa looked around, and the cold sweat ran on his back.

It had been years since he last shed cold sweats. What he saw terrified him again!

In the sky, the arm of him that he had chopped off was falling from high in the air. Before it touched the floor, the arm started to smoke. The dark smoke kept rolling up, and the entire arm instantly melted into some watery blood… At last, even the blood disappeared.

"What poison is it?" Wu Fa kept holding the wound on the shoulder and felt the chill in his heart.

As an expert in cultivation, he knew well how horrible the poison was. In fact, it was appalling. He knew how strong his body was, yet it only took a few seconds for the poison to completely destroy his arm. How appalling was that?
