Zhang Yan slowed down and said to Yan Luo and Meng Yao, "I want to see if the black fog here is indeed so magic! And I am hurry to use the anti-soul stone, so I'll continue to seek. You two leave first."

"What?" They two suddenly stopped, frowned and looked at the mad Zhang Yan.

"Are you crazy? Do you know how many people are trapped to death here? You dare to stay? You will die!" Yan Luo questioned loudly.

"If you die here, who else can teach me the spirit tattooing skills?" Meng Yao also cried aloud, "Don't be stupid! It is a matter of life and go out with us!"

"Hurry up!" Yan Luo anxiously shouted.

Zhang Yan smiled and shook his head, "Thank you! I will be fine! I promise to go back to the inn within two days." He waved his hand, turned around and ran to the top of the mountain.

Yan Luo and Meng Yao looked at Zhang Yan's back, shook their head and looked at each other in confuse. But they dared not to stay here. The fog was about to rise and they two began to hurry down. As they just ran out of the North Mountain, the thick black fog covered the mountain again, as if the door to hell was closed and swallowed everything in it.

Meng Yao shook his head in disappointment, "I didn't expect him to be such an arrogant person. It seems that he can't come back."

Yan Luo also sighed, "I rarely find an eating partner. Unfortunately, he is still too young! How dare he have the nerve to risk such danger!"

"My fault! I should have stopped him! I should have forced him out. We lost such a genius!" Yan Luo regretted.

A changed abruptly hit Meng Yao, and she revealed a meaningful smile, "He is so talented and confident. Perhaps, he really has some special means to survive in the fog. Let's go to the inn and wait for him. I believe he can come out."

"That said, I don't think he is such a reckless person, but after all, the danger in the North Mountain is known to us. No one has survived in so many years. Can he really do it?" Yan Luo was still full of doubts, but in his heart he looked forward to Zhang Yan's surprise.

While walking quickly toward the top of the mountain, he was still looking for the anti-soul stone on the ground. But after years of exploitation, the stone was really scarce. No one was found after a long time. Only when he almost reached the halfway up the mountain, he found a piece of the anti-soul stone.

Excited, he quickly swept the soil on the stone, but to find it was only with a size of one-third of the fist, which disappointed him. But it was better than nothing, he placed it in his storage ring satisfyingly, and comfort himself, "I will find a bigger one in a while!"

He stepped quickly and it became darker and darker around him. He happened to discover that there were many small holes in the trees, like pores of human beings, emitting black gas continuously. When the gas was concentrated together, it formed the black fog.

He realized at this moment that the black dense fog was come out from the tree. Not for a while, he was wrapped in it. He could only see the area within one square meter under the faint light of the crystal lamp. He tentatively put out his soul energy to explore the road, but the energy was indeed blocked as the saying goes.

Moreover, the thick fog could even devour his body little by little. Like sulfuric acid, it corroded his skin. Fortunately, as a body cultivator, the strength of his body and skin were especially fierce and the fog could not penetrate into his body in short time.

But daring not to be careless, he immediately mobilized his spiritual energy to form a shield. To his surprise, the fog not only corroded his soul and body, but even his spiritual energy.

He began to lunch the Asura Change to strengthen the shield. All of a sudden, the black dense fog around him seemed to see something terrible and fled and fled away. The unexpected powerful Asura Change enabled him to walk in the fog without any fear.

"The black fog seemed to be alive, amazing!" He sighed with doubts.
