During the dinner, Xiaochuan asked Xiang Liang about the three words "Mountain So-and-So" on the treasure box, saying that this mountain was a clue to return home. Xiang Liang liked Xiaochuan's resourcefulness and wanted to keep him, so he secretly blocked Xiaochuan. On the night of the Mid-Autumn Festival, Xiaochuan made mooncakes with his own hands and admired the moon with Xiang Yu, but he missed his relatives outside of time and space. It was also the Mid-Autumn Festival night. Gao Lan was alone at home and came to Yi's house. Professor Yi and Dachuan discussed how to open the treasure box. Yi's mother arrived. Her family has been experts in making and unlocking locks for generations. Dachuan repeatedly asked her to help, but Professor Yi refused. Mr. and Mrs. Yi had been divorced for many years and started quarreling when they met. This made Gao Lan think of his lonely life and shed tears. Xiaochuan read through the seal script literature of the Six Kingdoms at Fan Zeng's house, and finally recognized that these three characters were "Tang Wushan" in Yan seal script, and was about to set off to Yan to search for Tang Wushan. Unexpectedly, Xiang Liang proposed that he had to pass three passes to leave the division early. The first level tests the art of war. The second level of wrestling involves trying to lift the cauldron high with one hand. Ogawa thought of a way... In the one-handed tripod lifting competition in the second level of Episode 4, Ogawa used the principle of leverage to set up bamboo poles to easily lift the tripod off the ground, and surpassed him in time and height. Xiang Yu. Xiang Yu was angry that he was opportunistic, so Xiang Liang judged Xiaochuan as the winner. In the third stage of the competition, Xiang Yu determined that he would not be defeated, but Xiaochuan, who wanted to return home, knew that he was no match for Xiang Yu, but still fought to the death. When Xiang Yu saw that Xiao Chuan had decided to leave, he couldn't bear to stop him, so he clamped his horse between his legs. Xiang Yu fell from the horse. According to the prior rules, if either side falls off the horse, they will lose the game, and Xiang Yu also fulfilled his undefeated promise. Xiang Liang judged Xiaochuan to be the winner. Xiaochuan was very happy, but he fainted from exhaustion. After waking up, Fan Zeng told him the truth of the game. Xiaochuan set off and Xiang Yu came to see him off. Before leaving, the two prayed to heaven and became brothers. On the way to Yandi, Xiaochuan lingered on the beautiful scenery along the way and couldn't help but take out his mobile phone to take pictures. In a forest, I encountered Lu Gong's family being kidnapped by robbers. Xiaochuan came to the rescue. Lu Gong expressed his gratitude and proposed the idea of ??asking Xiaochuan to escort them to Pei County. Xiaochuan readily agreed, but he had no idea that the two young ladies of the Lu family, Lu Pheasant and Lu Su, had secret feelings for him. When he dismounted from his horse to rest on the way, Lu Pheasant put on the golden feather coat he had prepared for his sweetheart and danced for Xiao Chuan. Lu Gong also expressed his intention to recruit a son-in-law. Arriving in Peixian County, Xiaochuan bumped into Liu Bang, who claimed to be Brother Liu, at a dog meat stall. After going to the restaurant, Xiaochuan realized that he had been deceived into eating and drinking by Liu Bang, and he was very upset. At this time, in front of the Lu family's door, local celebrities gathered to pay homage to Lu Gong. But Lu Gong refused to be sick and disappeared. This made Ogawa very curious.

Episode 5: The Lu family suffered a disaster on the way and suffered heavy losses. Mr. Lu was at a loss to make a living in the future. Lu Pheasant proposed to exchange his and his sister's money for silver. Xiaochuan passed by the door, but mistakenly thought that the two were discussing their lifelong affairs, and hurried away. Ogawa was about to take out his mobile phone to look for clues to get home, but found that the phone was out of power, so he decided to build a charger himself. With the help of Lu Pheasant, Xiaochuan successfully created the charger. In excitement, Xiaochuan hugged and kissed Lu Pheasant, which made Lu Pheasant blush and became even more convinced that Xiaochuan was his rightful man. Xiaochuan overheard the conversation between sisters Lu Pheasant and Lu Su and decided to help the Lu family survive the "financial crisis". Ogawa persuaded Mr. Lu to open a private school in the local area and advertised it to the public. In order to raise money for the private school, he also asked the Lu family to hold a "charity banquet" on the Double Ninth Festival, which raised a large sum of money. Lu Pheasant dressed up as a man and sneaked into the wine shop to "hype" the two young ladies of the Lu family to the public, and Lu Gong also wanted to recruit a son-in-law at the banquet. Lu Gong was angry and scolded his daughter for shouting and hawking in public. Lu Zhi told her father that in fact she really intended to choose a good husband for her sister at the Double Ninth Festival banquet, but she already had a candidate. Since Liu Bang witnessed Lu Pheasant's beauty on the street, he also decided to go to the Double Ninth Festival Banquet to give it a try. Many local celebrities came to the Double Ninth Festival Banquet. Liu Bang swaggered into the Lu Mansion, and his arrival caused a commotion among the people. Lu Gong listened to Ogawa's suggestion and added a seat for Liu Bang. Luo La, general manager of the Zhao Group, appeared at the institute. They have long funded the institute's archaeological work. Mother Yi likes Laura very much and intends to let Dachuan pursue Laura. Laura invited Dachuan to dinner, and Dachuan dressed up grandly. Gao Lan felt a little uncomfortable watching all this.

Through the guidance of a thousand-year-old demon, Dachuan found a map in the cracks of ancient medical books. There was also a song "Soup Witch Jue" on it. On the surface, it was about medicinal materials, but in fact it corresponded to the map coordinates. Yi's mother couldn't help but exclaimed when she saw the formula. It turned out that one of the formulas was the secret of their family. Mother Yi took out the ancestral ring of their Jin family, which was the key to the dragon lock. Mother Yi told them that as long as they find the descendants of the five elements of metal, wood, water, fire, earth and their family rings through the formula and map, they can open the treasure box. So they set off to Tu'an again to find the Woodwalker family.

In Episode 11, Professor Yi and his party found a stone tablet with the word "Tu'an" engraved on it, and then found a line of small words next to it "Xiaochuan came here for a visit". They were shocked. According to the degree of weathering of the words, At least two thousand years ago. They asked the locals and found out that there was a Fuhu Village in the area. There was a statue of the Fuhu God enshrined in the ancestral hall, and there were some special legends. So they decided to follow the villagers to the ancestral hall to visit the centenarian living in the ancestral hall. Unexpectedly, Laura and others came to the ancestral hall first to force the old man to hand over the ring. Professor Yi and his entourage arrived and started dealing with them. Gao Lan is very skilled, but Dachuan is no match for Laura. In order to regain the map, he has to hold on to Laura. The injured Professor Yi and Yi's mother were worried. Fortunately, the whole village came with weapons after hearing the news, and Laura Ye Feng and others fled again. But a corner of the map was burned. Yi's mother stepped forward and asked, and it turned out that the old man was a descendant of Mu Xingzhe, and they successfully got the second ring. At night, the centenarian told them the story of Tuan. At Princess Tuan's coming-of-age ceremony, slaves were given to Princess Yushu as coming-of-age gifts. Yushu danced gracefully and was astonished. Xiaochuan took out his mobile phone and recorded the video. The king asked Yushu to sacrifice these slaves to the gods, but Yushu couldn't bear it. General Jin ordered the great tiger of Tuan to be brought out, and the slaves were horrified. Ogawa once again relied on the magical power of the tiger-shaped pendant to defeat the ferocious tiger alone. Worshiped as a god by the slaves, the slaves asked Xiaochuan to take them to escape together. The thoughtful Deputy General Pang took out the map he had written down in blood along the way. That night, all the slaves escaped under the leadership of Xiaochuan. Unexpectedly, General Jin had been waiting on the road for a long time.

Episode 12 General Jin ordered the escaped slaves to be beheaded immediately. Yushu arrived in time and was determined to free the slaves. However, General Jin also wanted to kill them according to the law because they did not have princess documents on the slaves. One hand and one foot. When the stalemate reached a stalemate, General Jin proposed to compete with Xiaochuan, betting on the slave's life and death, and Xiaochuan accepted the challenge. In the last game, the slave holding the target with an arrow turned around when he heard his daughter's call, causing Ogawa to miss the shot and lose the game. All the slaves glared at the family and drove them away. The couple decided to die to apologize. Early the next morning, everyone found the couple who had hanged themselves. However, her daughter was still breathing, and Xiaochuan immediately used artificial respiration to revive her. Ogawa scolded everyone for their cold-bloodedness, and everyone was ashamed and buried the couple. Xiaochuan vowed at the two graves to let everyone leave safely, but he encountered Princess Yushu coming with a mask. Yushu expressed his admiration for Xiaochuan and could not bear that his life would be in vain, so he allowed Xiaochuan to escape alone. Ogawa promised Yushu and disappeared into the trees. Unexpectedly, not long after, Xiaochuan appeared in front of her again holding a bouquet of flowers. Ogawa is determined to keep his oath to save everyone, and is ready to face the third challenge. Yushu smiled slightly and told Xiaochuan that he had won. General Jin walked out of the woods with a knife. It turns out that in these three competitions, Yu Shu had already discussed with General Jin to test Ogawa's character. Princess Yushu announced in public that Ogawa had won. Slaves were also freed. Vice General Pang was finally impressed by Xiaochuan's personality and immediately knelt in front of him and swore allegiance to him. Everyone also knelt down and followed Ogawa. Professor Yi and his family listened to the old man telling stories all night, and Dachuan suddenly wanted to write a legend about Tuan. Gao Lan went out to take pictures and called to his brother and Xiaochuan towards the valley. He couldn't help but burst into tears. After crying for a while, he was so tired that he leaned on a big rock and fell asleep. Myth Episode Plot Introduction Episode 13 Episode 13 Gao Lan wakes up and is surprised to find that the treasure box is next to her. He hurried back to the ancestral hall to report to others. They couldn't believe it, so they decided to try it with two rings in their hands, and they really opened the dragon lock.

When he was disappointed, Gao Yao sent someone to invite Xiaochuan to a banquet. In the private room of the restaurant, the two brothers drank freely, and Xiaochuan became drunk. Suddenly a bucket of water woke him up. When he looked up, he found "Gao Lan" standing in front of him fiercely, and Gao Yao was also dressed in modern clothes. Xiaochuan thought that the past was just a sweet dream, and couldn't help but cry with his head in his arms, shouting that he wanted to go back to Qin Dynasty. generation, and sincerely want to break up with "Gao Lan". "Gao Lan" was moved to tears by his words. Xiaochuan felt something was wrong, and Gao Yao suddenly laughed. In an instant, the two changed back to Qin Dynasty clothes. Gao Yao formally introduced Xiaoyue to Xiaochuan, and Xiaochuan sighed that the two were really similar. But when I heard the name "Xiaoyue", I couldn't help but feel shocked. He took out the bracelet of the dead palace maid in Yushu Palace. Xiaoyue recognized that it was her sister's personal belongings and burst into tears. Gao Yao took Xiaoyue to Yushu's palace and told her that she was the emperor's favorite concubine. He asked her to carefully observe Yushu's daily life and preferences, which would be useful in the future. At night, Xiaoyue sat under the steps, thinking of her sister, brother, and Xiaochuan, and couldn't help but smile at the corner of her mouth... but she heard Yu Shu singing a song softly over there.
