After a while, the three mummies stopped burning, mainly because there was nothing else that could burn except for their clothes and a layer of skin.

Hua Qianlei and the other two walked forward and saw three soul beads emitting faint light from a pile of charred bones on the ground.

Yu Shenghan picked up these three soul beads and found that there were only a few yellow-level low-grade martial arts stored in it, which had no effect on them.

Hua Qianlei took a soul bead and looked carefully. After a while, Huang Yuying asked softly: "Senior Brother Hua, have you noticed anything?"

Hua Qianlei shook his head gently and said, "No, but this way of storing information is very similar to the legendary jade slips that record martial arts. However, the method of making jade slips has long been lost."

The three of them discussed for a while before continuing to move towards the central area of ​​the ruins. Along the way, they would encounter other warriors from time to time, but those warriors looked like they were facing a great enemy and had no idea of ​​communicating at all.

After dealing with several zombies casually, the three of them arrived at the edge of an area covered with thick gray fog.

Yu Shenghan looked at the thick gray fog in front of him and said, "This is the death area in the mouth of those people."

Huang Yuying quietly approached Yu Shenghan and whispered: "It's so quiet here."

Then the two looked at Hua Qianlei together, as if asking him what to do. Seeing this, Hua Qianlei said, "You can check it nearby, I'll study it here."

After saying that, Yu Shenghan and the others sat directly on the edge of the gray fog, then closed their eyes and tried to explore with their mental power. Yu Shenghan and Huang Yuying looked at each other and left.

Half an hour later, Yu Shenghan and Huang Yuying circled around the gray fog and returned to Hua Qianlei. At this time, Hua Qianlei also opened his eyes. He looked at Yu Shenghan and the others and asked, "Have you found anything?"

Yu Shenghan replied: "No, it seems that even the zombies don't want to get close to here."

Hua Qianlei nodded and said, "I didn't find any big discovery either, but I found that these gray fogs are essentially the same as the mysterious gases in the air I told you before. I have tested it just now. The fire cover can isolate the mysterious gases in the air, so I plan to test again whether they can isolate the gray fogs. You stand here first, I will test it. If the method is feasible, let's go in together."

Yu Shenghan and Huang Yuying nodded when they heard this, and then they saw an exquisite talisman appeared on Hua Qianlei's right hand. The quality of this talisman paper was obviously much better than the previous ones. There was a circle of fire surrounding it on the talisman paper.

This is the second-level paper talisman - the Fire Cover Talisman. Then Hua Qianlei kept pinching his hand with his left hand. When his left hand stopped, a red light flashed on the Fire Cover Talisman, and a transparent sphere surrounding him appeared, and small flames appeared from time to time on the sphere.

He nodded to Yu Shenghan and Huang Yuying and walked into the gray fog. However, as soon as he stepped into the gray fog, he immediately felt the gray fog around him constantly eroding his protective fire cover, which led to an increase in his spiritual power consumption speed. After realizing that he was not injured, he withdrew from the gray fog area.

Yu Shenghan and Huang Yuying saw that Hua Qianlei had just entered, but they came out not long after they had just entered. After he took back the fire cover talisman, he hurried forward and asked, "Senior Brother Fourth, how about it?"

Hua Qianlei said after hearing this: "The good news is that the fire cover talisman can indeed isolate the gray fog. The bad news is that the gray fog is more aggressive, so my spiritual power cannot last long."

Yu Shenghan asked after hearing this, "What should I do?"

Hua Qianlei said slowly: "Wait until I recover my spiritual energy first, let's go in together and try to explore it. Anyway, this gray fog area is not big."

Yu Shenghan and Huang Yuying nodded when they heard this, while Hua Qianlei sat cross-legged and recovered his spiritual power.

An hour later, it was noon. Hua Qianlei, Yu Shenghan and Huang Yuying, who had just recovered from their condition, were eating dry food.

After eating and drinking, the three of them began to prepare to enter the gray fog area. Hua Qianlei activated the fire cover talisman again. This time the body-protecting fire cover was relatively large, wrapping the three of them in it.

Then the three of them walked into the gray fog area together. As soon as they stepped into the gray fog area, they saw the dry bones under their feet. These were the real dry bones, which were broken immediately after touching them. The ground here had completely sandy and was surrounded by a yellow color, which seemed to have no vitality.

They continued to walk forward without finding any trace of creatures, whether it was a living zombie or the white bone skeleton in the mouth of the warrior.

At this moment, Yu Shenghan suddenly pointed to a not far away and said, "It seems there is a hole in the ground."

When Hua Qianlei and Huang Yuying heard this, they immediately looked over there. Through the thick gray fog, they really saw a dark hole.

Seeing this, Hua Qianlei said, "Let's go and take a look."

However, after taking a few steps, Hua Qianlei's face suddenly changed. He felt that the gray fog that eroded his fire cover increased exponentially, and his spiritual power began to be consumed quickly, so he quickly said loudly: "Get back immediately, hurry, hurry."

Before Yu Shenghan and Huang Yuying could react, they were grabbed by Hua Qianlei and retreated. However, the gray fog that eroded his fire cover was still increasing. At this time, Yu Shenghan, who had already reacted, quickly picked up Huang Yuying and said, "Senior Brother Fourth, you are leading the way ahead, I can keep up."

When Hua Qianlei heard this, she immediately turned around and ran forward. After all, Yu Shenghan was a second-rate peak warrior, so even if she held Huang Yuying, she could still follow Hua Qianlei tightly, and always put herself within the protection range of the fire shield.

After a while, they arrived at the edge of the gray fog. Hua Qianlei was very anxious at this moment. He could feel that his spiritual power was about to be exhausted, but he was still a distance away from the gray fog area. If it was as those warriors said that entering the gray fog area would die, then they would definitely die if they would lose the protection of the fire cover talisman.

But at this moment, he suddenly felt that the gray fog that eroded his fire cover had decreased, and then just as his spiritual power was exhausted, the three of them ran out of the gray fog area.

The moment he left the gray fog area, his legs were weak and he fell to the ground. The moment he fell to the ground, he vaguely saw a figure staring at him in the gray fog area, and then he fell into a coma.

Dong Changsheng stood in the grey fog, looking at Hua Qianlei who was unconscious outside, and Yu Shenghan and Huang Yuying who were crying with joy after the disaster, and turned around and left silently.
