After Lan Xuanshuang solved her opponent, she continued to explore in this underground ancient city. She met Sikong Daoxuan who was also moved here, but did not see the people of Ziyan Mountain.

Now the entire underground is pitch black, and only the Ancestral God Palace shines brightly, so the two of them naturally go to the Ancestral God Palace together. However, on the way to the Ancestral God Palace, they accidentally discovered a long-desolate stone hall. There was nothing inside the stone hall, but there were only a large number of ancient witch scripts and murals engraved on the surrounding walls.

At first glance, Lan Xuanshuang is a young woman, and Sikong Daoxuan is a white-haired old man. In fact, Lan Xuanshuang is much older than Sikong Daoxuan. However, Lan Xuanshuang wasted too much time in the "Xuandu Purple Mansion". If you are knowledgeable, Sikong Daoxuan is better.

As the Confucian priest, Sikong Daoxun has a deep study of this kind of ancient characters and can read them comprehensively. This is the advantage of inheritance. Whether it is Zhengyi or Confucian, it has a long history and an orderly inheritance. He knows very well many ancient characters and legends. In contrast, other sects have either been in the rise for a short time or have a lack of inheritance and cannot be compared.

Through these words and murals, Sikong Daoxuan learned the origin of Netherworld Valley. It turned out that this place was not a ruin used by the people of the witch sect to live in, nor an underground ancient city, but a tomb belonging to the great wizard Wu Xian. In addition, these words and murals also record the life and deeds of the tomb owner Wu Xian. It was not that Wu Xian built this tomb for himself, but that several other great witches from the Ten Witches of Lingshan built this tomb for Wu Xian.

Sikong Daoxuan withdrew his gaze from the stone wall and sighed: "The ancestor dragon swept the six-hero, the tiger looked at He Xiongzai, the prisoner was 700,000, and the Tuli Mountain. Although the great witches did not recruit 700,000 prisoners, the scale of this tomb was far beyond the ordinary tomb of the emperor. As the former lord of the witch sect, Wu Xian was of course worthy of such a tomb, but it was a bit strange to have such a scale."

Lan Xuanshuang slowly stroked the words on the stone wall with her fingers. Although she could not compare to Sikong Daoxuan, who had been learning for most of her life in her study, she had been in contact with the people of the Witch Sect for so long in the Five Elements Cave Heaven, and recognized some of the Witch Sect's words and said in confusion: "According to the records on this stone wall, Wu Xian was bewitched by the demons and eventually died of the heavenly tribulation. This tomb is actually a place similar to the suppression of the Daomen Demon-Suppressing Well, used to suppress Wu Xian, who has turned into a demon."

Sikong Daoxuan pondered: "The so-called temptation of demons is mostly used by people in the witch sect to cover up the truth. The legend of the Ten Witches of Lingshan to save the subordinates of the Emperor of Heaven is well known. The Ten Witches of Lingshan used immortal medicine to save Yuqi, but after being rescued, his temperament changed drastically, and he ate people everywhere, and was finally shot and killed by the Emperor of Heaven. What is the difference between Yuqi and the demon with a great change in temperament? Because of this, the breaking and exodus of the six witches of enlightenment has shown that the legendary immortal medicine actually has great flaws. If Wu Xian personally used the immortal medicine in order to improve the immortal medicine or other reasons, then it is not impossible to become the so-called demon."

Lan Xuanshuang stroked the stone carvings and trembled slightly: "If this is true, then will Wu Xian die or live? If he is already dead, then that's fine. If he is still in the world, wouldn't we..."

Sikong Daoxun answered the question: "This tomb reminds me of the 'Ghost Kingdom Cave Heaven' of Zaoge Sect. As the leader of Zaoge Sect, Mrs. Lan should also know that the 'Ghost Kingdom Cave Heaven' steals the creation of heaven and earth for its own use and builds the cave heaven with human power. It is nothing surprising from the outside, but it hides Sumeru in mustard seeds, reshapes the earth, water, fire and wind, and forms a world of heaven and earth. This kind of cave heaven can not only confuse the secrets of heaven, but also reverse yin and yang and turn death into life. It is a method that is almost the immortals in heaven."

Lan Xuanshuang is not a stupid person. He knows that Sikong Daoxuan answers without answering. If this place is indeed the second "Ghost Kingdom Cave Heaven", then whether Wu Xian is alive or dead is not a difficult problem.

Lan Xuanshuang pondered for a moment and said, "Will the Five Demon Master have anything to do with Wu Xian?"

"Maybe there, maybe not." Sikong Dao Xuan said, "It is said that the Five Demon Masters are proficient in the witchcraft methods and are likely to have obtained the inheritance of the witchcraft. Now it seems that there is no doubt about this matter. However, how the Five Demon Masters get the inheritance of the witchcraft is still to be discussed. Whether it is Wu Xian's oral teaching in person or whether the Five Demon Masters learned from the remains left by Wu Xian, there is a big difference."

Lan Xuanshuang pondered for a moment, nodded slightly, expressing her approval of this statement.

Sikong Daoxun continued, "So there are great variables and many possibilities. For example, Wu Xian is already dead and there is only one Five Demon Master, which is the best result. For example, Wu Xian is not dead, and there are two immortal people here, which is the worst result. For example, Wu Xian is the Five Demon Master, one unit and two souls, etc.."

Lan Xuanshuang was tempted to retreat, and was worried that she would not be able to explain to Li Xuandu in the future. She couldn't help but ask: "Do we have to make a long-term plan?"

Sikong Daoxuan did not answer immediately, but walked out of the hall. Lan Xuanshuang hesitated for a moment and followed closely.

When he came to the stone hall, the entire mausoleum was still pitch black, and only the huge hole above the Ancestral God Palace and the Ancestral God Palace was bright. Sikong Daoxun raised his hand and pointed at the huge hole that fell from the sky light, and said, "This is a combination of two swords. It should be that Zhang Luanshan, the new great master of Zhengyi Sect, has arrived. It can be seen that we are not fighting alone, and reinforcements are constantly coming. The Confucian and Taoist families joined forces, not to mention the immortals, even the great masters of the heavenly realm of creation have the number of hands. Why do we fear?"

After hearing what Sikong Daoxuan said, Lan Xuanshuang stopped giving up easily, and turned to: "Are we going to find the people of Ziyan Mountain next? Or to find the great master?"

Sikong Daoxuan pondered: "This place has many mysteries. If you want to find someone, it will be time-consuming and laborious. In my opinion, we don't care about anything else and just go all the way to the key to the tomb here. Whether it is Ziyanshan people or Zhang Tianshi, they will definitely go here, and we will meet together at that time."

Lan Xuanshuang nodded and said, "Then it depends on the words of Mr.."

...

There is also a portal in the tomb chamber.

Qin Su said to Lu Yanbing: "Bingyan, you will return the same way and inform others of the situation here. Zhang Zhenren and I will continue to move forward."

Lu Yanbing hesitated for a moment, knowing that his cultivation level was insufficient, and it would be a burden to continue. He solemnly said: "You guys are careful."

After saying that, Lu Yanbing turned around and left.

Zhang Luanshan took the lead in walking towards the portal on the other side of the sarcophagus, and Qin Su followed closely behind.

After passing through the portal, the two seemed to enter another world.

"Where is this?" Qin Su looked around and saw a strange place, with clear black and white. She was standing on a loess road without a beginning or end, with a vast white area around her.

She looked down at the loess road at her feet, then raised her head and looked forward, murmured, "Under?"

"It's not the underworld." Zhang Luanshan's voice came from behind her. It was Zhang Luanshan who first entered the door, but appeared behind Qin Su.

Qin Su looked back and saw Zhang Luanshan walking towards her along the dirt road under her feet, and slowly said, "Although this is not a sacred place, it is not a sunny place."

Qin Su wanted to detect the surroundings with his divine thoughts, but found that the white mist around him completely blocked his divine thoughts. He couldn't help but frown slightly, "Where is this?"

Zhang Luanshan stood side by side with her and said, "The Yin-Yang Gate is to walk through the gap between the two realms of Yin-Yang and get around the distance barrier between the sun, and be able to take hundreds of miles in one step. As long as the cultivation level of Xuanyuan Realm can use the Yin-Yang Gate, how mysterious should the "Yin-Yang Gate" of the immortal person? If the portal we just passed by is also an extremely special "Yin-Yang Gate"..."

Qin Su took a light breath: "We are in the gap between the yin and yang worlds?"

Zhang Luanshan whispered: "It's probably that."

After saying that, he strode forward, and Qin Su hesitated a little and also took steps to follow him.

The world is clearly black and white, the earth is black and the surroundings are white. The only difference is the sky and roads, which are dead gray and earthy yellow.

The two of them walked on the yak road one after another, with white fog on both sides of the road, and they couldn't see what was hidden in it.

I don’t know how far I walked, but this yellowish road began to widen. When the road was ten feet wide, this road that seemed to have no end finally came to an end.

Qin Su stopped and looked at it, and saw that at the end of the road was a very simple "door", with only two stone pillars and a "door lintel" crossing the stone pillars, barely forming the shape of a door frame. At this time, the black fog rolled between the door frames, making it difficult to see what was behind the door.

Zhang Luanshan did not turn his head, but raised his hand and pointed to the huge stone gate ten feet high. "After passing this gate, you will be the core of the tomb."

Qin Su narrowed her eyes and looked at the rolling black fog in the stone gate. The black fog reminded her of the Demon-Suppressing Well in the Great Zhenren Mansion. The seemingly narrow dry well was also so black fog that made people daunting.

Zhang Luanshan looked at Qin Su and said in a deep voice: "You must be extremely careful when entering this place, and there must be no omissions."

After saying that, Zhang Luanshan ignored Qin Su's reaction and stepped directly into a black fog between the stone gate.

Qin Su was silent for a moment, and then stepped through the stone gate.

When the two of them entered the stone gate, what caught their eyes was a deep and invisible downward road. It was dark and faint, and it was difficult to distinguish between northeast and northwest, and it was difficult to distinguish between up and down, front and back.

Qin Su could only follow Zhang Luanshan slowly. He didn't know how long he had walked, but his eyes suddenly became clear and a huge altar appeared at the end of his sight.

There are nine steps connected between the altar and the ground. Venerable Yun and Lin Yan stood on both sides of the steps on Monday, and there were a large number of soul gourds placed around the altar according to a certain sequence. Some gourds have been opened and have lost all their spirituality, which is no different from ordinary gourds. Some gourds have not been opened yet, but still emit a faint fluorescent light.
