Fang Xiu's robe was different from before, with a huge Bagua pattern on the back. He was wearing cloud boots and walked down from the sky with Chen Jin and Heisha. The basic rules of the Mountain and Sea Realm were basically modeled after the Earth. Gravity, environment, air, and the length of day and night were very similar. So according to the rules, Chen Jin and Heisha could not fly in the outside world, and they could not fly here either. Without Fang Xiu, they would have to walk step by step on the ground. Heisha was now transformed into a girl with black pointed ears, wearing a loose black robe with light-colored prints on it. This robe did not look like an outfit for going out. The hem was long and dragged on the ground, and it was too elegant and luxurious. However, it looked very beautiful and full of majesty and domineering style. Heisha liked it very much. Chen Jin was wearing a light-colored curved skirt with a long sword on her back. She followed behind Fang Xiu, taking small steps on the water, looking cute and serious. The three of them walked onto the shore, and Fang Xiu looked around, as if he was choosing a place. "This is it!" Fang Xiu pointed his finger at the air and gently drew it. He saw that the land and a mountain peak within a radius of dozens of miles were shaking violently like an earthquake. All the creatures on the mountain were frightened and fled in all directions. Flocks of birds flew into the sky and fled far away. This piece of land was separated from the surroundings and turned into a small island. Fang Xiu and the other two took the small island and drifted far away, all the way to the North Sea of the Mountain and Sea Realm. As they walked farther and farther, they saw the edge of the world deep in the island. The sky also became dark. The whole world fell into an empty dead sea. The ocean here was extremely violent, with huge waves sweeping everywhere. The water curtain even swept all the way to the sky. The sky was full of broken marks. Whoever broke into here would break into a dead place. There was no trace of any living thing here. There was only a lonely silver moon in the sky. This is the edge of the Mountain and Sea Realm, a place where the sun can never be seen, a cold place of death. And this moving island has always been floating above this dark sea. It has no fixed position. It moves with the ocean currents and sea water, like a place in the world without a trace. Fang Xiu raised his hand upwards, and the soil on the island gathered into boulders, white jade, colored glaze, and gemstones. The trees automatically split and formed, and various spiritual materials combined freely and continued to gather towards the center of the island. Various materials continued to combine and build, and soon, an ancient city appeared on the island. Fang Xiu brushed his hand over, and a large wooden pier appeared on the shore where they stood. The ground was paved with slabs and stones, leading all the way to the ancient city in the center of the island. The three people walked towards the ancient city, and they could see that the ancient stone city wall was more than six feet high, huge and majestic, and the city gate was opened, and they could see that the spacious streets inside could accommodate nearly ten carriages in parallel. On both sides of the road, there were ancient buildings, most of which were several stories high and looked like shops. There were also many tall buildings made of stone and wood in the city, and pavilions and towers more than ten stories high were everywhere. Fang Xiu stood under the city gate and waved his hand to see two distorted characters like oracle bone script appear on the city gate. "Youdu!" Fang Xiu stretched out his hand, and the Book of Life and Death appeared in his hand. With a stroke of the white jade brush, all the animals trapped on the mountain underwent magical changes. Various animals opened their spiritual wisdom and transformed into human forms. At present, the most powerful monsters and lives in the mountain and sea world are at the Qi Refining stage, while most of them are just ordinary beings and a small number of small monsters with spiritual wisdom. Apart from this, there are no more, because Fang Xiu is only at the Qi Refining stage and has not yet explored a way to go further. Fang Xiu walked inside, and the streets and places they passed by saw lights lit up one by one. The whole ancient city seemed to be lit up, and thousands of lights were lit. Fang Xiu took Heisha and Chen Jin to the center of the ancient city, and saw a high palace in the center. The base alone was dozens of meters high, and there were stairs leading to it. Standing on it, you can overlook the entire Youdu city. Hundreds and thousands of monsters gathered in the square under the palace stairs. Most of these little monsters who had just awakened their intelligence were not even fully transformed, and their souls were not complete. Most of them looked a little dazed. They wore tattered clothes and looked like a group of ancient zombies. Fang Xiu turned his head and said to Heisha, "Heisha, these will be your people in the future! You are the master of this Youdu City, what do you think? Haven't you always wanted to be a king? Now you are the king!" Heisha pointed at himself, in disbelief, tilted his head and said, "Meow! Me? So powerful!" Fang Xiu nodded, "There are even more powerful ones!" Fang Xiu closed the Book of Life and Death: "Youdu is the place of reincarnation of the three realms, floating on the edge of the world. Here are entrances to the mountain and sea realm, the underworld, the fairyland, and even the real world, and you are the one who is in charge of such a powerful place, the mysterious Lord of Youdu, a figure who has existed since ancient times." "How is it? Isn't the character setting I made for you very awesome!" Fang Xiu looked at Heisha and said. "Wow~!" Heisha opened his mouth wide, as if he had thought of something and had some kind of beautiful dream in his imagination: "In that case, if these guys want to go to the underworld, the fairyland, and other places you mentioned, they must get my permission." Then it immediately remembered something, lowered its head, and looked at Fang Xiu speechlessly: "But none of these places you mentioned exist." "Ahem!" Fang Xiu coughed awkwardly twice: "They will all be there in the future! They will all be there!" Fang Xiu then stated the real reason for building Youdu City in a serious tone: "Then those people from the outside world or demons and monsters who enter the Mountain and Sea Realm, that is, the people in the real world, no matter how they came in, if they want to leave here and return to the real world, they must go to Youdu City and get permission from you, the Lord of Youdu, before they can leave!" Heisha felt very happy, his imagination ran wild, and his face flushed: "Let everyone beg me? Wouldn't that mean I can do whatever I want?" Fang Xiu nodded and said unscrupulously: "That's right, your task is to do everything you can to give them difficult questions and ask for everything you want, magic weapons, skills, or even work for you and make money for you!" "It will take them a lot of hardship and twists and turns to complete it, but it can't be a condition that they can't complete." If you let people from the outside in, you must give them a way out, but it's impossible to let them in and out casually. Even some powerful and dangerous guys, Fang Xiu doesn't plan to let them out at all. Fang Xiu patted Heisha's shoulder and looked at the hundreds of scattered little demons below. These guys have just opened their spiritual intelligence and are not much better than animals. At present, the entire Youdu City is an empty shell, and there is nothing in it. "So Heisha, your next task is to stay here and build Youdu City. Work hard, I will come down to see you in a few days!" "Come on! Heisha Queen! Lord of Youdu!" After Fang Xiu finished speaking, he immediately took Chen Jin and stepped into the distance. Heisha suddenly felt something was wrong, as if he had been tricked. He looked at Fang Xiu warily and suspiciously and said, "No! You are trying to trick me! I don't want to stay here. There is nothing here. There are no mobile phones, no computers, and no delicious cat food." "There is nothing here! I don't want to stay here!" Fang Xiu left a word and stepped into the sky, then completely disappeared into the air: "I won't let you out if you don't do well! You just stay here!" Heisha ran on the stone slabs of the palace with her long skirt, chasing Fang Xiu's light, just like Chang'e chasing the moon: "No! Let me out!"
