After Tang Yu left, he quickly arrived at the City Lord Mansion. He still climbed over the wall and went in. As soon as he entered, a group of patrolling soldiers passed by. He quickly went into hiding and was not discovered. He looked at the map and saw that his location was not far from the city lord's youngest son. He followed the route to avoid the patrols. Soon arrived at the room of the youngest son of the city lord. He entered the room through the window. There was a man lying on the bed in the room, who was supposed to be the youngest son of the city lord. He feared that the city lord's youngest son would wake up for the soldiers to find out. He gave the city lord's youngest son a little drug, wrapped it in a quilt, carried it on his shoulder, and left the city lord's office the same way he came. Because he was pregnant with the youngest son of the lord of the castle, the speed of the car slowed down, and he was almost spotted several times. Luckily, he was in danger.

After leaving the Castle Lord's area, it is much easier to walk without the dense patrols of the Castle Lord's area. Soon, Tang Yu returned to their hiding place in Kangji and put the city lord's youngest son on the bed. He began to feel his pulse, because it was not far from dawn, and when the eastern and northern cities were under attack, he had to heal the little son of the city lord. Tang Yu helped the city lord's youngest son finish his pulse and showed a hint of a smile because he had healing pills and wouldn't talk nonsense. He directly fed the city lord's youngest son a pill and then gave him an injection. At the same time, he injected his weakened qi into his body to absorb the medicine. Tang Yu practiced the magic technique of reconciling yin and yang, and he had reached perfect control of his true qi. In addition, he found that using True Qi to heal illnesses would be very effective. However, for ordinary people, the usual true qi, even a faint trace of true qi, would be unbearable for them. Tang Yu can make his true qi in a balanced state through the transformation of yin and yang, and will not cause harm to ordinary people. After doing all this, Tang Yu helped the city lord's youngest son cover the quilt, looked at the two stunned men next to him and said, "I hope he can wake up soon." ”

The scholar was just curious, because he had never seen a doctor treat such a disease, and Yasuji admired it even more. He admired Tang Yu's medical skills even more and benefited a lot.

It was getting brighter, but the city lord's youngest son had not yet responded. Tang Yu was also a little anxious in his heart. He couldn't help but wonder if his medicine was ineffective. No, these medicines are strictly prepared by ourselves. There should be no problem. Just when Tang Yu was puzzled, Kang Er suddenly said, "Big brother, he's awake." When Tang Yu heard that the city lord's youngest son had woken up, he was very happy and hurried to the bedside. The city lord's youngest son saw Tang Yu and said, "Who are you, what do you want me to do?"

At this time, the scholar stepped forward and said, "This scholar's uncle." The youngest son, Xiaohu, the city lord looked at this scholar, suddenly burst into tears, and said, "Uncle scholar, you must avenge your brother. Guo Lao killed his brother. ”

"What, Xiaohu, what are you talking about?" the scholar asked in surprise.

"Uncle, when my brother said that he had discovered Guo Lao's secret and wanted to tell his father, but as soon as he left my room, I saw that his brother was caught by Guo Lao, and he hurried over. He tried to call for help, but he couldn't make a sound. I wanted to help him, but as soon as I rushed out of the room, I saw his brother fall to the ground. At this time, Guo Lao saw me. He was running fast and suddenly appeared in front of me. He gave me a pill. I don't know what happened next. We must tell our father as soon as possible that he is an undercover agent from Nancheng," Xiaohu repeated what he remembered.

"It's been many years, and your brother is still there," the scholar said. ”

"What's going on?" asked Xiaohu, puzzled.

"Let me tell you that the son who is now, I have also heard of the eldest son whom he killed at that time, so as not to doubt it. He brought his son to the lord's government. Because the city lord has been fighting for many years and has not come back for a long time, he doesn't know what his son looks like, and he has always regarded the current Liu Jinlong as his son. At that time, what Xiaohu saw was real. Later, Guo Lao gave Xiaohu a pill that made Xiaohu crazy, so we must expose Guo Lao" Tang Yu told everyone the truth. Everyone nodded heavily, especially Xiaohu, who was more worried that his father would be hurt by Guo Lao. The scene of his brother's murder is still etched in his mind.
