Hearing Qin Feng''s words, both the black Python essence and the little squirrel were startled, especially the black Python essence, whose huge body trembled and almost fell off the edge of the cliff.


    "My Lord, we have unwritten rules in the demon world that we can''t show up in front of the world." the black Python spirit showed a embarrassed look and was frightened.


    "Unwritten regulations?" Qin Feng was stunned. He always wondered how he could shrink into the mountains and rivers with his strange, murderous and murderous nature. It turned out that there were such unwritten regulations.


    "What are the specific regulations? Tell me."


    Black Python Jing hesitated and said, "in fact, two or three thousand years ago, there were many powerful humans in this world. At that time, they were called Qi practitioners, and some were not even weaker than the demon king. However, during the period when Qi practitioners were popular, I don''t know what happened. All Qi practitioners disappeared, and even some Qi practices didn''t stay, just like they didn''t exist at all."


    "With the disappearance of Qi practitioners, no one can stop the pace of the spirit world, but no one thought that a very strange thing happened soon after the spirit world entered the human world."


    "What''s the matter?"


    "All monsters, regardless of their strength, as long as they have cultivation, have entered the dormancy period. After waking up, this unwritten rule appears in the minds of each monsters. No monsters can appear in the world for any reason. Violators will die of natural punishment."


    "At that time, monsters were unrestrained and crazy. They didn''t take this inexplicable rule to heart at all, but..." said here, the black Python''s face was obviously frightened: "a demon king died of lightning because he was exposed to the world."


    "Since then, no monster dared to break this rule."


    Qin Feng''s eyes narrowed. Does Tianding really exist in this world?


    He personally tends to be artificial. Anything that can''t be explained will eventually be pushed behind by black hands.


    "Dozens of years ago, a large-scale battle took place on this planet. There was an extremely powerful demon king. During the evolution of the demon emperor, human beings inadvertently saw that the last demon king had almost entered the realm of the demon emperor, but he died inexplicably." when he said here, the black Python''s face obviously showed a sad color.


    "That powerful demon king is the last ancestor of my family, breaking the dragon. This ancestor succeeded in turning the dragon, but he broke this rule. Is it heaven''s punishment in the end?"


    "My Lord, it''s far from the Tianshan Mountain in the northern region. It has to pass through many human living areas. If it is seen by humans..."


    Qin Feng waved his hand: "all the heavenly punishments are just man-made."


    He knew that heaven''s punishment might be a reason. The most important thing was that they were afraid of the demon king.


    However, Qin Feng is not afraid. Since he wants to experience the red dust of Kyushu, he must have an overall understanding of the world.


    "Let''s go!" Qin Feng waved his big hand and roared out with his mental strength. He covered his body and rushed to the Tianshan Mountain in the north with black Python essence and little squirrel.


    Although the two places are far apart, they are not far away in front of Qin Feng, who can travel hundreds of thousands of miles a day.


    In the afternoon, they arrived at the Northern Tianshan Mountains.


    "The demon king is in the Tianchi Lake," said the black Python spirit, a little afraid.


    Although it is also a demon king now, after all, it has just entered this realm, and there is still a great gap with the famous old demon king.


    On the Tianchi Lake, Qin Feng showed his body shape and stamped his feet. The whole Tianchi Lake trembled violently.


    On the water surface, the waves rolled and the bubbles kept rising. Finally, the pool water separated to both sides, and a black monster surfaced.


    This is a huge black red beast with a pair of flesh wings, like fins, and only one eye on the head.


    "Human? How dare you come here." the monster in the pool made a slow voice with a cold tone: "hurry up, or don''t blame me for being rude."


    "Do you have this ability?" Qin Feng smiled.


    The so-called demon king, in his opinion, is just the nine layers of heaven under the forbidden area.


    "I heard that you were a monster two or three thousand years ago. I want to know something. Tell me what you know!" Qin Feng said faintly.


    "Human, you''re looking for death." suddenly, the strange tone in the pool became a little anxious: "bastard, go quickly and don''t force me to do it."


    Qin Feng smiled faintly. When he was about to speak, his face suddenly changed. The sky was clear for thousands of miles. In a twinkling, there were dark clouds, which made people suffocate.


    "No, it''s heaven''s punishment."


    "It''s over."


    The two voices came from the mouth of the black Python essence and the monster in the pool.


    Especially the monster in the pool, with a look of despair, once heaven''s punishment comes, even the most powerful demon king will die.


    In the past, even the demon emperor died in heaven''s punishment.


    "Damn mankind, you killed the king. Today the king will die with you."


    With that, terrible water columns burst out in the pool water, impacting Qin Feng, black Python essence and little squirrel.


    However, these water columns automatically burst within ten feet of them.


    "Is this heaven''s punishment?" Qin Feng raised his head and narrowed his eyes.


    Weng!


    Suddenly, his pupils contracted and his whole body trembled. A voice was very vague, like from outside.


    "This is... The sound of all souls mourning!"


    Qin Feng shook. The heavenly punishment was made by the tomb keeper. The sound was filled with the sadness and cry of all souls. He was almost familiar with this sound. This was the sound made by the tomb keeper''s big clock.


    For a moment, Qin Feng thought of many, lantern gods and tomb guards. Why should they intervene in the world.


    The disappearance of Qi practitioners thousands of years ago, the strange sleep and unwritten regulations must have a great relationship with the tomb keeper and the lantern God, but what is all this for.


    "Tomb keeper elder." Qin Feng arched his hand at the sky.


    Both the monster in the pool and the black Python spirit looked at him in surprise, because this sound could not be heard without reaching a certain level.


    Seeing this scene, Chi Zhonggua, who was going to fight hard, gradually calmed down and his eyes twinkled, because the heavenly punishment was slowly receding.


    "Heaven''s punishment can''t check and balance this human? There are such terrible friars in the world?" the strange face in the pool was surprised.


    The sky gradually cleared up and the dark clouds dispersed. The monster in the pool was completely relieved. He looked at Qin Feng and became awed.


    "Elder, do you want to investigate the upheaval thousands of years ago?" it asked respectfully.


    Qin Feng nodded. He felt that some questions needed to be solved, and all this might be attributed to the upheaval made by the tomb keeper and the lantern God thousands of years ago.


    "Well, my Lord, I''ll contact the other three demon kings. They are all from that era," Chi Zhongguai said quickly.
