"True or false?" Chu Xuehan asked with some doubts. If in other places, Chu Xuehan's soul mind can penetrate a hundred feet underground, but here, Chu Xuehan finds that her soul mind can only scan the area ten feet below the ground. If it is more than one foot, she can not detect anything. Tang Ao also found that the soil here is different from other places, and it seems to contain a special force.

This force is somewhat like a border, but Tang Ao is sure that this is not a border, but Tang Ao is not clear about what it is. Compared with the snow cold of Chu, Tang Ao's soul idea can explore a little further. With full exertion, Tang Ao's soul idea can explore the underground area of three feet. And Tianji pupil is even more powerful. After operating Tianji pupil, Tang Ao can observe the range of ten feet underground.

"Bang!" After finding the soul jade, Tang Ao took out a long gun and smashed it towards the ground. However, the land refused to be extremely hard, Tang Ao shot down, and actually wiped out a string of sparks on the ground, and Tang Ao's arm was also shocked numb.

"This land is so hard!" Tang Ao looks at the red ground and marvels. Tang Ao's spear is made of refined steel. But such a long gun can't break through the soil here. "Well!" At the same time, Tang Ao recalled a rare immortal material in the general outline of Yun Xiaoyao refining utensils.

This material is called Tiangang clay, which is a kind of black gray soil. Tiangang mud is a second-class material of immortal level, which can be directly used to refine magic soldiers. Only because the Tiangang mud is black gray, and the soil here is red, so Tang Ao did not think of it for a while. After a careful comparison, Tang Ao found that the red soil in addition to color, other features are really the same as Tiangang mud.

"Will..." Tang Ao thought of a terrible possibility.

"What would it be?" Chu Xuehan's big eyes are full of doubts, looking at Tang Ao.

"I have probably understood that the little fox is right in his choice. The soil and the soul jade in the soil are treasures. This soil is the second grade immortal material Tiangang mud. Most of the reason why the Tiangang mud here is like this is that some great warriors died here during the war, and their blood dyed the land red. "

Here Tang Ao pauses for a moment: "and the cultivation of these warriors is obviously not weak. After falling for such a long time, resentment still exists. Their resentment goes deep into the ground, hindering the exploration of the warrior's mind. And these resentments gather but do not disperse. After losing consciousness completely, they form a soul jade in the earth

After Tang Ao said his conjecture, Chu Xuehan felt a little inconceivable, but on second thought, it seemed to be a very reasonable explanation.

"Be careful!" When Chu Xuehan thinks of these, Tang Ao suddenly hugs her. Tang Ao is holding Chu Xuehan and flies into the air with great speed. But Rao is Tang Ao quick reaction, Chu Xuehan or by a bone thorn from the snow-white fragrant shoulder rub, draw a bright red blood line. A touch of black corpse poison is about to drill into Chu Xuehan's body, but is burned to ashes by a golden flame in Chu Xuehan's body.

The golden flame suddenly appeared, but soon disappeared. If it was not for Tang Ao holding Chu Xuehan, Tang Ao could not see the golden flame. But when the golden flame appeared, Tang Ao felt a very strong pressure from the golden flame. This kind of pressure, Tang Ao in the Ming emperor and other big emperor level strong body have not felt.

That kind of pressure is more powerful than the pressure on the emperor. Tang Ao's eyes are a little embarrassed to see Chu Xuehan. Chu Xuehan knows the mysterious golden flame in his body, but Chu Xuehan doesn't understand the origin of the golden flame. It seems that the golden flame was born, but for so many years, Chu Xuehan did not learn how to use the golden flame.
