Qingxu Zhenren led everyone to the back of the boulder, pointed to a huge stone slab underground, and said: "Ladies and gentlemen, the entrance to this middle palace is below, and we will go down in a while." There is a thing in the poor road said in front, there are nine yin dragons and the eye of the anode underground, and the two breaths of cold and heat take turns, and if anyone feels that they can't resist the invasion of cold and heat when we go down to the cave, don't be strong, and return to the ground quickly, otherwise I am afraid that it will cause irreparable damage to the body. ”

When everyone heard this, they immediately became nervous. Du Wu didn't care, and said, "Grandpa Dao, let me open this entrance." ”

Qingxu Zhenren nodded and said, "Master Du Wu, this stone slab weighs two thousand catties, can you move it?"

Du Wu grinned, revealing the tiger teeth on his lips: "Grandpa, I have been able to eat since I was a child and have great strength, and two thousand catties of things are nothing." ”

As he spoke, he put down the big palladium and looked at the slate carefully, only to see a huge iron ring on one side of the slate, which was supposed to be used to lift the slate. Du Wutan grabbed the iron ring with his right hand, said "get up" lightly, and lifted the huge stone slab with one hand and put it aside.

When everyone saw Du Wu with such divine power, they couldn't help but applaud. I don't know where so much power comes from in her small body.

Qingxu real people also secretly applauded. I thought that it was really a talented person from all generations, and the future rivers and lakes belonged to their young people, and this little girl must be a shining star on the continent in the future.

After the stone slab was lifted, everyone saw that there was an extremely deep cave below, and there were bursts of yin qi coming out of the mouth of the cave that was square to a foot, and they could feel the coldness through the bones before they touched it.

Du Wu saw that there were two iron cables as thick as eggs at the entrance of the cave, and they were only exposed after lifting the stone slab, and the iron rope was nailed to the boulder next to it.

Qingxu Zhenren said: "These two iron cables are used to enter the formation, this middle palace is the most difficult to walk, you need to climb the iron rope and go down directly, unlike other eight palaces have steps to walk, so the difficulty is also the greatest, a poor road will go down first, everyone follow me, once you feel that you can't stand the cold and heat, return immediately, can you hear clearly?"

Everyone hurriedly agreed.

Qingxu Zhenren took out a fire fold from his arms, shook it in the wind, hit the fire fold, still held the beast Yemen with his right arm, held the fire fold with his left hand nameless and tail finger, pinched an iron rope with his thumb and two fingers in the middle of the index, and went down the hole. Du Wu tied the Qiankun Geography Palladium to her back, also grabbed an iron cable, and followed Qingxu Zhenren down the hole, behind her was not worried about Du Wu, and accompanied her to protect her Wu Kesong Old Knight, followed by the eleven teenagers and two seniors of the two sects. Everyone grabbed the rope and slowly slid into the hole.

As soon as they entered the cave, everyone felt that an extremely heavy yin qi enveloped their whole body, and this yin qi seemed to be able to invade the bone marrow. Busy with their own internal strength to protect the whole body. These people who came have been practicing since childhood, and their internal skills are quite foundational, and they suddenly feel better about this exercise, but they are still cold and biting.

The cave is very dark, only the light of the fire fold in the hands of the pure and void real people, everyone looks around by this bit of light, only to see that the cave is very small at the beginning, the more the area of the hole is larger, it seems to be a big big and small bell mouth shape.

After descending for about a hundred zhang, the cave wall can no longer be seen, only the darkness around the light of the fire fold.

After going down for about two hundred zhang, he suddenly felt a black shadow flying in the dark, and in addition to Du Wu in the team, there were still two women, who were frightened and exclaimed: "What is that!" Qingxu Zhenren said: "Don't be afraid, this is a bat in the underground cave, they live underground all year round, feed on mosquitoes and flies, and will not harm humans." I've heard that there are vampire bats in some caves, but not here. ”

The two women felt a little relieved, but they were still a little scared.

Du Wu was not afraid at all, and said, "Grandpa Dao, how long will it take to get to the end?"

Qingxu Zhenren: "We have just descended 300 zhang now, and there are about 1,200 zhang." Can you still stand it?"

Someone in the team heard that it was so deep, and they couldn't help but cry out in their hearts, the cold on their bodies was getting heavier and heavier, and the iron rope seemed to be like ice cubes in their hands. A few people had already retreated, but they didn't want to be the first deserter, so they silently insisted.

Du Wu also felt a little cold at first, but she was blessed with innate true qi, so she was not very uncomfortable, when it was getting lower and lower, and the cold was getting heavier and heavier, Du Wu secretly carried the nine turns of Qiankun, and the true qi circulated in the body for a week, so she didn't feel any cold.
