Chu Xunyu has been digging the cave mountain hard. This craft is very particular. The excavated cave passages must not only accommodate people in and out, but also ensure that they will not collapse, otherwise they will bury people alive. During the war between the two dynasties, Chu Xunyu specially found the brothers of the "Duziying" to learn about the war, and now they are just right to use them.

The tunnel was digging deeper and deeper, and it was slanted straight down. Chu Xunyu had an unknown premonition in his heart. Who would have dug such a deep cave in the abyss tens of thousands of feet underground? Could it be another existence like the owner of an old house? Want to fulfill his ambition underground? Judging from this posture, it is naturally a great power to be able to dig such a deep place. If you set up an ambush in a mechanism, without the help of Mu Yuan Buddha Light, Chu Xunyu could not guarantee that he would escape unstoppable.

The site selection of the tunnel is very clever. Chu Xunyu dug along the traces of earth and rock excavation, successfully avoiding the underground undercurrents and almost never encountered any danger. This time Chu Xunyu was completely unfounded because he was too old and had few traces left, and there were no such things as murals and texts to guide him. Chu Xunyu could hardly see any information about this tunnel. Unknown things are full of dangers. This is the experience summarized by Chu Xunyu during the war between the two dynasties. Will it come true this time?

When the 21st shovel was dug, it finally reached the end. Chu Xunyu probably had already penetrated nearly a thousand feet deeper. Although he was injured, his martial artist was exhausted and panting. At the end was a large stone wall. Chu Xunyu tried to bypass and see the situation, but he failed. Behind the stone wall, there should be a stone chamber. Although the area is not large, Chu Xunyu dared not bypass and dig randomly without authorization, because he could faintly hear the sound of water flow, which means that there was an undercurrent not far away. If he wanted to bypass this stone chamber, he would be sure to dig through the river. At that time, the undercurrent would rush out and be flooded again. It seems that if he had to pass this level, he would have to force himself into the stone chamber.

Chu Xunyu told Liu Jue everything he saw and heard. Liu Jue couldn't help but feel a little scared when he heard it. Chu Xunyu knew that she was afraid of stepping into a trap like the owner of the old house. Youdao was bitten by a snake once and was afraid of the ropes for ten years. When he was in the old house, he still had Mu Yuan a Buddha light to destroy all evil spirits. But this time he was gone, and Chu Xunyu's injuries were not healed. If he met someone, he would definitely be broken here. But Chu Xunyu thought about it, so he began to comfort Liu Jue, Youdao was to put it to death and then live. Now he only found such a way out, and it was a way that his predecessors had walked. Even if he was very dangerous, it was a place to go. If he was lucky, he might be able to escape from heaven. It would be better to be buried alive here. He would just die alone. It would be better to see which ancestor left behind.

Liu Jue was still a little afraid, but agreed with Chu Xunyu's thoughts. Chu Xunyu was a little surprised. Liu Jue smiled bitterly and said, "Life is suffering and life is tragic. I seem to be in control by my master and my parents. I am like a puppet on a rapture line. When I return to the outside world, I live like a walking corpse. It is better to accompany my senior brother to see this underground death situation. It is not in vain for life. There is only one wish, that is, before death, we can leave our name, a line of origin, and a family member, and look at my fellow disciples. My life is also bright. I can enter the realm that ordinary people dare not enter, and can go to the place that ordinary people dare not go to." These words were a bit arrogant. Chu Xunyu knew that she had been suppressed for a long time. This time she was on the verge of despair and was completely aroused from the rebellious spirit in her bones.

Chu Xunyu was also very proud, and slapped his sword on the spot and said, "Don't be afraid, sister, Wei will often struggle in the realm of death in his life. So he went deep into the tiger's den with his sister today. Not to mention anything else, even if the swords and fires are still allowed to go first, how can a dead person scare the man's courage?"

This was so passionate. After saying that, he packed up his things and jumped into the tunnel with Liu Jue. He came to the stone wall. Liu Jue touched the stone wall with his hand and felt cold. Could it be that he was immersed in the ground for many years? A faint cold air was revealed, and it seemed that he had been buried deep for tens of millions of years. I don’t know when I saw the light again. Liu Jue suddenly found that there were many small holes on the surface of the stone, which were dark and thin, and he could pinch it with his fingers.

"This is the 'Wrath of Sulphur Fire'." Chu Xunyu explained.

"The Wrath of Sulfur Fire?" Liu Jue was puzzled.

Chu Xunyu told Liu Jue that this kind of stone is rare and comes from the lava when volcanoes erupt. It can only be found in a few places with volcanoes on the sea or on the land of China. The temperature of the lava is extremely high and there is a sour and sulfur smell. After forming this stone, it is as light as boneless, but it is indestructible. Moreover, this stone can emit high temperatures for a hundred years, so people call it "The Wrath of Sulfur Fire", which means that the volcano erupts is the meaning of the mother of earth's rage. Looking at the appearance here, Chu Xunyu speculates that it should have been taken down by someone back then. This is tens of thousands of feet underground. Even if a cultivator lives here for a long time, he will not be able to bear the birds. There must be some way to drive away the cold and dampness. Now it seems that this piece of sulfur and fire is indeed the best choice, but it has been buried deep for many years and the heat has long dissipated.

"Then how can we open it in?" Liu Jue asked.

"Junior sister, why are you asking me? You have to rely on your junior sister, you can take action." Chu Xunyu couldn't help but smile, "Today, it is also worth the ruins buried deep underground to be dug through us. The fury of sulfur and fire is extremely hard after cooling down, but it is born with the principle of mutual generation and restraint between yin and yang. If you have 'Pity Frost' in your hand, why worry about not breaking the bluestone?"

What this said is, the wrath of sulfur and fire is the most hot thing in the world, so it is born with the principle of mutual generation and restraint. The Lianshuang Ice Python is here, swallowing and spitting the cold ice, which is enough to penetrate the stone wall. Liu Jue nodded and released the Lianshuang Ice Python. At this time, it had been resting for a few days, recovering a lot of energy, absorbing the stone wall and swallowing and vomiting cold air. The stone wall has been buried underground for a long time and has been eroded by the cold and damp air. It can't resist the cold air that the ice python swallows and vomits. In just half an hour, it collapsed the crack of the stone wall. Chu Xunyu flew over and kicked out the hole.

After the entrance of the cave collapsed, Chu Xunyu immediately put his sword on the entrance of the cave to warn him, but the cave was quiet and dark, and there was no reaction. Chu Xunyu blew the fire and got in with Liu Jue one after another. Liu Jue tightly grabbed the corner of Chu Xunyu's clothes, as if he was afraid to step into the previous desperate situation here.

The fire broke with the fire was very small, and the lighting range was limited. Only a black shadow seemed to be bullied in the cave. Chu Xunyu did not dare to go too deeply, so he stopped at the door to prevent accidents. He tore off the corner of his clothes and tied a simple torch. After lighting it up, the two of them were surprised to see it on the spot...
