After the triumphant return of the Qin army, Qin Mugong began to turn his gaze to the northwest. During the time when Qin Mugong led the army to the expedition, the intelligence in the treasury had already piled up, and he separated the secret documents about Xirong and read them first. He was glad to see that his plan had gone very smoothly, and that the beautiful girl band had stirred up the Xijon tribes.

It turns out that King Rong and the lords of the major tribes have been fascinated by the beautiful girls. Some Rong lords began to be jealous for a certain woman. In order to balance the relationship between the allies, King Rong left four of the most enchanting and charming women for himself, and these four people left the band. He gave the rest to the leaders of the twelve tribes, but when it was time to perform, he had to gather the members together.

During a tour, one of the most powerful Rong masters, Qiu Ru, actually detained all the girls and took them for himself. The rest of the Rong lords were furious and immediately filed a complaint against the king of Rong. King Rong was also furious, because he himself only possessed four, so he united with the bitter lords to attack the tribe, and captured Qiu Ru and imprisoned him.

You Yu's period of stay in Qin had long expired, and he repeatedly requested to return to China, and King Rong also sent several letters, but they were all prevaricated back by Qin Mugong for one reason or another. After returning from Kunshan, Qin Mugong felt that the time had come, so he let You Yu go.

After two years, when Yu Yu saw King Rong again, he no longer recognized the other party's appearance. The guy in front of him, who was once known as the "No. 1 Warrior of Xirong", is now holding up his huge belly, and he walks over to greet You Yu step by step, and the fat on his body trembles with every step. King Rong's face was swollen with alcohol bubbles, his cheeks were flushed, and his forehead and head were greasy and oily; He laughed heartily in his arms, spewing the stench of scavenging animal mouths in his mouth.

Yu Yu glanced at the other Rong lords who came to welcome him, and they all looked similar. King Rong turned to his warhorse, which snorted and shook its head and took a few steps back; One attendant tugged at the reins, and another crouched down and hugged one of his thighs, trying to lift him up. However, when the servant stood up, his center of gravity was unstable, and both of them fell to the ground, and a burst of laughter erupted around them.

King Rong scolded twice, and laughed with everyone; He was laboriously arched on his horse for the second time. Yu Yu couldn't help but shake his head and sigh.

That night, King Rong held a grand welcome banquet for Yuyu, and the beautiful girl orchestra of the Qin State also participated in the performance. Yu Yu scratched his heart and liver, and couldn't help but lower his head. "Such beauty and temptation can't even resist yourself, let alone those who have never seen the world?!" He thought.

On the third day, he found King Rong and said solemnly: "O king, the thirteen tribes of Xirong are one, and Qiu Ru is also our brother, and brotherhood cannot be broken up by women, and the minister thinks that he should be released." Moreover, our king should also send the female music back to the Qin State, and not let them disturb the ancient order that has lasted for thousands of years. The three women of Yuxi, Daji, and Bao Xi can perish for three generations, is it still a problem for eighteen women to destroy Xirong? ”

"It's okay to release that fool. But by Yu," King Rong asked, "which of the three tyrants do you think the widow resembles in the last days?" ”

You Yu continued: "Uncle Qin sent those women to provoke his brothers, and detained his ministers to divide the monarch and ministers, and his heart to kill me was revealed. Although my king is a sage, how can the Qin people be cunning. The best way to deal with the Qin people is not to accept their temptation. ”

King Rong said, "There is a degree of widowhood, don't say any more." ”

The current situation of Xijon has become completely different from that before Yuyu's departure. The men of Xijon all wanted to have Chinese women, and women began to pay attention to taking care of themselves and learning how to please men. Due to the fact that the wine is not separated, drinking flower wine has become a common entertainment activity, and brawls caused by jealousy are not uncommon; The color of wine makes people depraved, makes people depressed, and makes people lose their hearts.

You Yu locked himself in his home and reflected painfully: "It turns out that the lethality of my words is so great!" "The Qin people used temptation to destroy the natural moral system of Xirong and lure people to degenerate; But Xirong no longer has time for a saint like the Yellow Emperor to formulate ritual laws, and the Qin people will never give them this opportunity. "Sijon is about to perish, where will I go?"

A few days later, Qiu Ru was released, but his son had established himself as the new head of the tribe and refused to relinquish power. As a result, the tribes that had captured Qiu Ru had to attack his tribe again in order to take back the leadership for Qiu Ru. Qiu Ru's son was outnumbered, so he had to lead his followers and flee to Qin.

In order to thank Yu Yu for coming to the rescue, Qiu Ru specially made a big scene to entertain him. After the feast, Yuyu stayed in the tribe. But in the middle of the night, the beautiful woman who belonged to Qiu Ru climbed into Yu's bed. Yu woke up thirsty in the middle of the night and saw the woman hugging him tightly, and he was immediately frightened. He immediately stormed the door and fled home overnight.

The next day, Qiu Ru came to the door angrily and strongly asked King Rong to hand over You Yu to him for disposal. King Rong laughed so hard that he fell to the ground (because he was too fat to bend down), and he said, "Qiu Ru, you finally understand what it is like for your brothers' women to be taken over by you, right?" Forget it! I didn't expect that Master Youzi looked like a man with thick eyebrows and big eyes, and it turned out that he was not exempt from vulgarity! I'll just say that Qin Nu is far from enough! The widow will ask Uncle Qin to send more women over. ”

Yu immediately became the laughing stock of the entire Xirong, not to mention the performance of political enemies, his colleagues pointed fingers at him, and even his friends began to look down on him, calling him a hypocrite. In view of this, King Rong had to give him a long vacation so that everyone would not feel uncomfortable with each other when they met.

But during the period when Yu Fuxian was idle, rumors unfavorable to him came one after another, some people slandered him for being bribed by the Qin people to betray Xirong, framed him for coming back as a spy for the Qin people, and provided a lot of evidence, true or false.

At first, King Rong only laughed about the rumors, and then forbade the rumor-mongers to continue to speak out. But he secretly sent his cronies around to inquire about the situation, and Qiu Ru did the same thing as King Rong. Later, the Rong arrested several mysterious Qin people, and although they claimed that they were just merchants, the Rong people had reason to suspect that they were spies who had come into contact with Youyu. King Rong has lost trust in Yuyu since then.

The unfavorable news came one after another, and Yu Yu felt tired and exhausted. He knew that the mastermind behind this series of events was the Qin people, and he felt that a great disaster was approaching him, and he once said to his son: "I am afraid of the result of the confrontation with the Qin people. ”

After thinking about it, he was powerless and unwilling to fight for himself and be loyal to Xirong; In the name of hunting, he escaped from Xirong and defected to Qin with the help of Qin spies.

Yu Yu was well aware of the situation of the various departments of Xirong, he was in a high position, and he was also very close to the high-ranking nobles; His defection was not only a great loss for Xirong, but also a great gain for the Qin state. Duke Qin Mu gave him the high position of a secretary, and at the same time ordered him to assist Meng Ming in carrying out the plan to defeat Rong.

Soon after Yu defected to Qin, the envoy of King Rong also arrived. He put forward two requirements: first, continue to contribute beautiful girls who can sing and dance, the more the merrier; Second, hand over You Yu to them and take it away.

Qin Mugong was furious, and he replied: "Eight hundred is already the number of the Son of Heaven, and Rong Zi is not enough, does he want to be above heaven and earth?" Rongzi could not use Yu, so Yuyu fled to Qin; Now that he has become a secretary, Rongzi wants to arrest the secretary of Qin, just to start a war against Qin! The widow has nothing to run for his life, and he will be with him to the end! ”

The Qin drove the envoys out of the capital and began to gather their troops. You Yu wrote a letter to Qiu Ru, who had occupied the twelve hairpins, which read: "You and I grew up together and became brothers with different surnames, you know that I will not do that kind of dirty thing." But because of you, I lost everything in Xijon and had to flee to the Qin State.

"The Qin army is about to march west, your tribe is the closest to Qin, of course I can propose to attack you first, and your tribe will definitely be the first to be destroyed. But I have decided to give you a chance: if you can become the vanguard of the Qin army, and destroy the enemies who once humiliated you like your brother with a different surname, not only will you not be attacked, but you will get everything that King Rong has! ”

In July, the Qin army rose up and launched a full-scale war against Xirong; Soon, Qiu Ru led the tribe to surrender to the Qin army. The coalition then tore a hole in the heart of the tribal alliance, so that the tribes could not care for each other. Meng Ming selected an elite unit and handed over command to You Yu. Yu Yu led this elite army with Qiu Ru all the way, and the goal was directly aimed at the Xirong royal court. Unable to organize an effective defense, King Rong climbed into a cart carrying women and fled north.

King Rong's escape has torn the alliance apart. The Qin army broke through each and finally ended the war just as winter was approaching. This time, the Qin army of the western expedition destroyed twelve large tribes and opened up thousands of miles. Envoys from other countries and tribes poured into Yongdu one after another, congratulating the great achievements of the Qin State, expressing appreciation for the destruction of the twelve tribes of the Qin State, and willing to support Qin Mugong as the king, and the Qin State eventually became the overlord of the Western Regions.
