Grandpa stopped abruptly when he said this, picked up the water cup and took a sip of water, in his eyes, Lin Hai could still see the horror of that night decades ago, and it was still buried deep in his grandfather's heart, what happened that night? What kind of tomb is there on the dragon's back that makes grandpa still fear decades later? Lin Hai didn't want grandpa to continue talking, but he really wanted to know the secret.

Grandpa calmed his breath, shook his hand at Lin Hai's dissuasion, and continued to tell the story of what happened that night on the dragon's back.

"What is it?" Taigong and the others looked at the fat old man who was stuck in thought.

"Old man, if I'm not mistaken, this is not a soul-sucking place, but a yin-sucking place" The fat old man's lips trembled and looked at Taigong.

"What? You say this is a place to suck the out?" Taigong looked at Fat Dun in confusion, and Fat Dun nodded.

"Suck the yin, absorb all the negative things, the moon is yin" Taigong muttered and looked up at the top of the mountain, his pupils suddenly contracted, and the others looked at him, and suddenly felt that the scalp was fried, and the cells were starved of oxygen, and they were dumbfounded.

I saw the black clouds on the top of the mountain, but at this time it was like a human face, I couldn't see my eyes and nose, only a huge mouth was sucking in the light of the moon in the sky, and the moon at this time seemed to have a silver river flowing into the big mouth. No wonder it was pitch black under their feet, and the light of the moon was intercepted by the black cloud mouth at the top of the mountain.

"Look," Mao Tong said in surprise, pointing ahead. Everyone looked along the flashlight he shone out, only to see snakes and piles of insects, ants and spiders, at this time they were chattering to the top of the mountain, but when they reached the mouth of the dark clouds, they all disappeared mysteriously, but the back was still not afraid of death layer by layer overflowing to the top of the mountain, all of which saw that everyone was scalp numb, goosebumps rose up, and the whole person felt cold.

"Sure enough, it's a yin-sucking place, but nothing that is negative or cold blood can escape, the night of the full moon is when the yin qi is saturated, we are in a hurry," Taigong said slowly.

"Then what should I do, obviously, the entrance to the tomb should be under the cloud mouth, but such a large formation, I'm afraid it's not easy to get it" The sloppy man looked at the cloud mouth that was still swallowing, and his heart was very unwilling.

"What do you see, old man?" Taigong shouted at the fat dun who was still in his thoughts.

"It's better to suck the yin, it's safer than the soul-sucking place, we are all male, but we're not afraid of being sucked, but I don't understand whether the following is caused by the corpse transformation or the anomaly of the occurrence of strange treasures, and now, the surroundings are clogged with poisons, but it will be difficult to get close to the research for a while" The fat old man shook his head and said helplessly.

"That's right, this yin-absorbing place should only have this kind of anomaly when the yin qi reaches a certain level, if it is always like this, there are still so many poisonous insects entrenched in this dragon's back, I'm afraid we will have to avoid it a long time ago, we should just be at the right time, it seems that we have to wait" Taigong said after a while.

A few people felt that this was the only way, everyone squatted on a big rock, and watched the snakes and insects in the distance continue to rush to the top of the mountain, which had the meaning of a big gathering, but they didn't know whether to go to the soup and fire, and there was no return.

"Old man, I'm afraid it's not a way to wait like this, this full moon night, the moon can still be seen until dawn, there is a moon, I'm afraid that this yin place will not stop, and when the day dawns, the sun comes out, we're afraid we can't even find the tomb, you don't see the cloud mouth is so big, such a large area, how can we find it then, is it difficult to dig the whole mountain to see the soil", waited for a long time, saw that Yunzui had no signs of stopping, and Fat Dun said impatiently to Taigong.

"That's right, just um, old man, you don't think about it?" Taigong seemed to have thought of something, and looked at Fat Dun in surprise, and Fat Dun nodded.

"That's right, only by casting a spell to block yin and yang can we buy time," Fat Dun said.

"However, this method of blocking yin and yang, every time it hurts the body, it will cost you your life," Taigong said with some unbearability. The others also nodded, only Grandpa didn't know what they were talking about.

"No, if there is no harvest this time, you said that we still have a few years to live, you lost a little boy, I lost three, there is only one boy and a sister bud left, I can't afford to lose it" Fat Dun was anxious and said loudly, the pain in his eyes showed that he did this, and he was forced to do so, and there was a trace of helplessness flashing in everyone's eyes, Taigong looked at the grandfather sitting beside him, his eyes were full of love, raised his head, Taigong looked at Fat Dun Maotong and the sloppy man, and stood up decisively.

"Okay, even if it's for the sake of the child, I'll accompany you this time" Taigong looked at Fat Dun eagerly, Fat Dun smiled gratefully, and the sloppy man and Mao Tong also nodded helplessly.

Fat Dun took out a super large compass that was 2 sizes larger than the general compass, Taigong took out a black and white jade piece from his backpack, Mao Tong took out a leather bag containing dog blood and a yellow talisman, but the sloppy man took out a rusty iron sword.

"This time, take me as the center, if I can't survive the backlash, if you have a capture in the back, my two babies will please you," Fat Dun put the compass on the ground, sat in the direction of his back to Yunzui, and said to everyone with a serious expression, everyone looked at each other and nodded seriously.

The sloppy man sat opposite the fat dun, facing Yunzui, Taigong and Mao Tong sat opposite each other, everyone closed their eyes quietly for a while, the scene looked very weird, grandpa had already been arranged by Taigong behind Shi Yan, hiding there and looking at the four of them puzzled.

After a while, Taigong opened his eyes, put the black and white jade on the compass in a certain direction, and then closed his eyes again, after a while, the sloppy man also opened his eyes, pointed the rusty iron sword at the fat dun, and the fat dun also opened his eyes at the same time, bit the tip of his tongue, and spit a mouthful of blood on the iron sword, followed by another mouthful of blood spit on the black and white jade, Mao Tong also suddenly opened his eyes, opened the skin bag containing dog blood, and poured a circle around the four people, Fat Dun closed his eyes again, only Mao Tong and the sloppy man were still standing, Mao Tong's yellow talisman swept around the bloody iron sword, and there were words in his mouth, and suddenly, Mao Tong, who closed his eyes and recited the mantra, opened his eyes, his eyes were shining, and at the same time, the yellow talisman in his hand suddenly burned, and the sloppy man's eyes were also shining, and the tip of the sword in his hand was stained with the dust of the yellow talisman, and he pointed the tip of the sword straight in the direction of Yunzui. I saw a burst of yellow light suddenly rising from the black and white jade piece, and along the tip of the sloppy man's sword, a fist-sized pillar of light slowly shot towards the direction of Yunzui.

"Spiritual power is not enough" The sloppy man held the sword in one hand, pointed at the jade with one hand and two fingers, and suddenly shouted, Fat Dun heard the sloppy man's words, his eyes opened suddenly, and another mouthful of blood spit out to the jade, and the yellow light that was thicker than just now rose from the jade again, and through the sloppy man's two fingers into the sword body, a stronger pillar of light shot towards the cloud mouth. And Taigong and Mao Tong next to him pressed their two fingers on a certain direction of the compass at the same time, and the entire compass suddenly rose with a red light, covering all four of them inside, and grandpa couldn't see them. It's just that from time to time I hear the voice of a sloppy man shouting not enough and the sound of a fat dun spurting blood.

A yellow pillar of light finally arrived at Yunzui, directly cutting off the Milky Way that connected Yunzui and the moon.

I saw that the cloud mouth was trembling and twisting, as if he was angry, and as if he was hissing, grandpa even felt that the ground was shaking, and the snakes and insects that woke up fled back desperately, and for a while rolled down the mountain like a tide of sea water, passing by Taigong and their side was blocked by a black wall of black dog blood, and there was a red light inside, but they were far away from Taigong and them. The moonlight on his head also penetrated in, and the ground under his grandfather's feet was a silver light, no different from other places, looking up, the cloud mouth had dimmed, slowly disappearing, and the yellow pillar of light was also slowly dispersing, and the yellow light points seemed to form a thin paper-like partition wall around it, and the light of the moon could not shine into it.

"Is this the separation of yin and yang?" Grandpa was amazed and muttered to himself.

"Ahem" A coughing sound came, grandpa found that the Taigong who was covered by the red light showed up, the red light had disappeared, the cough sound was made by the fat dun, but now the fat dun can no longer be called the fat dun, at this time he and Mao Tong have a comparison, his face is pale, his eyes are dull, his lips are trembling, and the corners of his mouth can see bloodshots, and the whole person looks a lot older. And the three of them are better, although they are also pale, but there is still a divine light in their eyes.

"Old man, why are you so troubled, it's good to have blood on the tip of your tongue, you actually forced the blood out of your heart, when can you get good wow" Taigong looked at the fat dun of the old Longzhong, and said with concern in his eyes, and the sloppy man and Mao Tong also had pity in their eyes.

"Aren't I afraid that the follow-up will be weak, a drop of blood in my heart is worth three mouthfuls of blood on the tip of my tongue, and I can cut it off as soon as possible, I'm lazy, okay?"

"Okay, you guys hurry up and find out the doorway of the tomb first, I have to take a rest, or I'm afraid I won't be able to get out of the tomb if I enter the tomb" Fat Dun waved his hand again, asking the princess to quickly find the tomb.

"Okay, my eldest boy will stay and take care of you, the three of us will find the tomb and come to pick you up" Taigong saw that Fat Dun said this, and saw that the time was also tight, so he hurriedly took Mao Tong and them to climb to the top of the mountain.

"Hehe, little guy, come here uncle, the two of you are warmer, how do I feel a little cold" Fat Dun waved his hand to his grandfather, but he didn't see his grandfather coming, but he was startled at a glance. I saw that on my grandfather's back, he was carrying a woman with a cloak and red all over her body, and this woman's pale face was facing her, and her face was a cold and penetrating smile.

"Ga" Fat Dun almost turned his back on his breath.

"How can this be, the black dog's blood didn't kill her, and the sucking ground has no effect on her, what kind of evil thing is this, this is too violent, all eyes are dirty,, this is the doom that will fall to me" The fat dun stood up.

Behind him, the two mud-eating evil creatures that his grandfather had seen were also slowly leaning towards the fat dun.
