After the Sui army retreated, Yang Fei stayed at Jingkou for a few days to prevent the Sui army from attacking again, and the imperial city of Yang Mansion also sent people to get Yang Yi's overlord gun many times, and Yang Fei insisted on taking his younger brother back in person. The news of Yang Fei's victory was also brought to the palace, and this month, Empress Chen did not feel the crisis and continued to spend all day drinking. At this time, Xuan'en's sister Xuan Guifei also learned that her brother was killed, and she was both angry and sad in her heart, since the death of her parents, although Xuan'en did all kinds of evil in the imperial city, but she did treat her sister extremely favored, when Xuan Guifei entered the palace, Xuanen was afraid that her sister would be wronged, and she was also strongly opposed at that time, and Xuan Guifei naturally had a very heavy affection for her brother. Concubine Xuan Guifei put a spiritual position for Xuanen in her palace, and she was in pain every day in front of the spiritual position.

Xuan Guifei's personal maid was the personal maid she brought over in Xuanfu, because she couldn't bear to see her young lady washing her face with tears every day, she began to find a way to take revenge on the Yang family. One day, Concubine Xuan's maid Xiaoxiang happened to hear Empress Chen's stand-in eunuch say that Empress Chen was obsessed with Yang Fei and Yang Yi's sister Zhang Xiaoxiao, so she quickly ran back to Xuanyi Palace to report to Concubine Xuan. Xiaoxiang returned to Xuanyi Palace and saw Xuangui Concubine lying on the bed today because of her grief and weakness. came to him and said: "Niangniang, I heard a news today, the emperor seems to have taken a fancy to Yang Fei's sister Zhang Xiaoxiao, and this is a good opportunity for us to avenge the master." After hearing this, Concubine Xuan opened her eyes and said: "What kind of opportunity is this? Yang Jiajun killed my brother, if Zhang Xiaoxiao enters the palace, the Yang family will have a backer, then how can we take revenge?" Xiaoxiang continued: "Niangniang's words are wrong, I also heard that Zhang Xiaoxiao didn't want to enter the palace, and Yang Fei and Yang Yi had mentioned letting Zhang Xiaoxiao enter the palace before they went on the expedition, but Yang Fei refused, the emperor was very faceless, it seems that the emperor is still angry about this matter." Niangniang, Xiaoxiang has a way to avenge the master. When Concubine Xuan heard that she could avenge her brother, her eyes brightened. Xiao Xiang continued: "Waiting for Yang Fei to return to the court, Niangniang announced that Yang Fei entered the palace in her own name, and pleaded guilty to the Yang family for the master's persecution of Yang Yi, and then I told the emperor that you are sick and let the emperor come over, and then you are Yang Fei who wants to assassinate you, and the emperor will definitely punish Yang Fei." The Yang family will also be implicated, and it will be difficult to turn over."

Xuan Guifei thought about it for a while, it was indeed a good way, and said to Xiaoxiang: "Okay, wait for Yang Fei to return to the court, and we will start to implement the plan, you go down first to prepare." Xiaoxiang saw that Concubine Xuan's mood suddenly improved, and she went down happily.

The next day, Yang Fei gathered the generals in the general's mansion and said to everyone: "Generals, my brother died in battle, my family has come many times to urge me to take my brother's relics back, now the Sui army has retreated, Yang Jian and I go back to the imperial city first, and the Yang family army has worked in Jingkou to work for the generals." After hearing this, the generals all said that they wanted to go back, Yang Fei continued: "Generals, your second brother will definitely be able to feel it in the sky, if we evacuate Jingkou, the Sui army will definitely continue to attack, and I hope that the generals can focus on the overall situation." Yang Fei thanked him. At this time, the generals were not arguing, and they all bowed their heads. Yang Fei turned his head to Yang Jian and said, "Yang Jian, you prepare, let's go back immediately." Yang Jian agreed, and then went down to prepare. Yang Fei came to the center of the hall, picked up the Overlord gun with both hands, turned around and left.

A few days later, Yang Fei and Yang Jian with a small number of people have come to the gate of the imperial city, first sent someone to report to the Yang Mansion, Yang Fei and his party entered the city, at this time the people in the city consciously gave way to a road, standing on both sides, as if to welcome Yang Fei into the city, Yang Fei carried the overlord gun, walking in front of the team, his heart was full of emotion, a month ago when he went on the expedition, it was still two brothers, and now he can only come back with his brother's weapon.

At this time, the people standing on the side of the road took out a white cloth around their waists and lifted it up, Yang Fei suddenly saw everyone's actions, and the bitterness in his heart was a little more, he knew that this was the people welcoming Yang Yi's heroic soul home. He looked at both sides excitedly. In the blink of an eye, Yang Fei came to Yang's mansion, at this time Yang's mansion was all wrapped in white cloth, Mrs. Yang, Zhang Qing, Mrs. Zhang, Zhang Xiaoxiao, Yang Steward and others were already waiting at the door, Yang Fei and Yang Jian quickly dismounted, ran to Mrs. Yang, the two knelt on the ground, Yang Fei said: "Mother, I'm sorry, I didn't bring my brother back, I'm sorry, I'm sorry." As he spoke, he began to cry, and the heroic general of the Yang family was now crying like a child. Yang Jian put down Yang Fei's fire dragon spear, pulled out the sword at his waist, and said to Mrs. Yang: "Madam, it's all my fault, if I stay with my second brother, he may not be..." Mrs. Yang stepped forward and greedily greeted the two of them and said, "I don't blame you, I don't blame you." Don't cry, don't cry. Let's go in, let Yi'er go home!" said while wiping the tears of the two people, and pulled Yang Fei into the house.

The Yang Mansion had already prepared the mourning hall, and since Yang Yi had fallen off the cliff, the coffin in the hall contained Yang Yi's relics before his death, just waiting for Yang Fei to bring back Yang Yi's weapons before his death and bury him. Although the overlord gun is the heirloom of the Yang family, only Yang Yi can use it, so Mrs. Yang decided to use the overlord gun as a funeral. Yang Fei carefully put the overlord gun into the coffin, and after putting it in, Yang Mansion began Yang Yi's funeral.

The news of Yang Fei's return also reached the palace, and Concubine Xuan was ready to start a revenge plan at this time.
