Zhang Nan pushed the bicycle and slapped the door of his home. Not long after, the door creaked and opened.

The one who came to open the door was Lao Su. Lao Su looked at Zhang Nan who was standing outside the door, rubbed his eyes in disbelief. After rubbing his eyes, Lao Su found that Zhang Nan had not disappeared and said excitedly: "Master? Is it really you?"

When Zhang Nan saw Lao Su's excited look, he couldn't help but be funny and moved. Then he said, "Of course it's me, otherwise who else can be there? Hurry up, open the door for me, I'm back, Master." Zhang Nan said with a smile.

"Hey." Old Su responded and opened the door, and Zhang Nan pushed the bicycle into the door.

After parking the bicycle, Zhang Nan asked, "Did anything happen in the mansion during the time when the master was away recently?"

"Oh, Master, you don't know that during the period when you were kidnapped by the thieves, the entire Chang'an City was crazy about finding you. Not only Lord Cui and Mrs. Cui ran to the mansion, but even the emperor had come here twice. Not to mention General Cheng and the others, they often personally lead people to find you all over the city and the mountains."

Zhang Nan nodded, all of which were within his expectations. Zhang Nan then asked, "How is Madam, are you okay?"

"Master, in the two days when you just disappeared, my wife couldn't eat well and couldn't sleep. She often sent people to inquire about your news. Later, didn't you send a letter back? My wife fainted after reading it." Lao Su said truthfully.

"Disappointed? How could he faint? Madam is fine." Zhang Nan asked anxiously, but he was still puzzled. No matter how bad his handwriting was, he wouldn't faint. Moreover, he was so strong after disappearing, why did he faint after the news?

"Minister Sun has come to see him and has prescribed a few medications. Now his wife is in good health." Old Su said.

"That's good, by the way, is the lady in the mansion now?" Zhang Nan asked.

"Mrs. I'm not at the mansion. My wife has returned to Cui's mansion. Since you are gone, your wife has fallen ill again, Master Cui has taken her back and asked Mrs. Cui to take care of her." Old Su said.

Zhang Nan nodded. This is also human nature, and Zhang Nan was also very worried about Cui Yue's health. Now it is taken care of by her father-in-law and mother-in-law. It is much better than Cui Yue's fight alone in the past.

"Then let it be. If you go to Cui Mansion, you will say, Master, I have arrived home safely and go and take the wife back." Zhang Nan walked into the inner hall and sat on the Grand Master's chair and said with a comfortable look on his face.

It’s still comfortable for your own home. This is Zhang Nan’s true thoughts.

"Hey, I'll go now." After Old Su said that, he left and ran to Cui's mansion to report the message. Zhang Nan sat on the chair and did nothing. He just came back and didn't know what to do.

Just as Zhang Nan was stunned and his brain was in a state of stuttering and blank, a familiar voice came from outside the door.

"Qingquan, you are here this time. Instead of going to find me first, you sit here in a daze and ask me to come to you personally. What crime should you be guilty of?" Before Li Er showed up, his voice became into Zhang Nan's ears. Then, Li Er appeared in front of Zhang Nan with an excited look on his face.

When Zhang Nan saw that Li Er was coming, he immediately stood up and quickly saluted Li Er and said, "Your Majesty, I've just come back, but your intelligence system is really powerful. Before I could sit on the hot side, you knew I was back." Zhang Nan said with a smile, but while Zhang Nan was smiling, Zhang Nan was also shocked.

Not to mention that Li Er's intelligence system is spread throughout the Tang Dynasty, at least there must be one in Chang'an City. I just returned to my mansion, which proves that at least as soon as I entered Chang'an City, Li Er got the news, otherwise it would be impossible for him to come so quickly.

"Hmph, don't talk about him, I'm asking you." Li Er pretended not to hear what Zhang Nan just said and continued.

"Oh, my emperor, I just sat down. Your Majesty, you can't treat patients so strictly." Zhang Nan said with a wry smile.

"Sickness? Qingquan, are you injured?" Li Er immediately became nervous when he heard that Zhang Nan was injured. Zhang Nan felt warm in his heart when he looked at this look. Although Zhang Nan didn't know whether this was Li Er's imperial mind or Li Er's true feelings, at least Zhang Nan felt very comfortable when he looked at it.

"There is nothing big. I just fell down my head when I fell off my head." Zhang Nan said. After that, Zhang Nan rubbed his head. Although the big bag is not very swollen, it still hurts when he touches it with his hands.

"Did you fall down? Or from the horse? How can this be done? Have you ever seen it?" Li Er asked with a frown. The emperor, who had been riding for half a lifetime and fighting for half a lifetime, still knew the seriousness of the fall down.

"Before I have time, you are here, Your Majesty." Zhang Nan said with a smile.

"How can this work? Why don't you ask Zhenren Sun to come and see you?" Li Er said.

"No need, even if Zhenren Sun comes, he can't tell anything." Zhang Nan said confidently. After all, the brain is the most complicated part of the human body. Even if he just falls his head, Sun Simiao cannot tell the problem. Without the help of modern technology, Zhang Nan knew that even if he really falls, he would have to wait for death in the Tang Dynasty.

"No, no, Liu Bing, hurry up and invite Sun Zhenren to Qingquan to see. This is a big deal. It's not a joke when you fall to your head." After Li Er said that, he waved back.

Liu Bing bowed his order and then hurried out to find Sun Simiao.

After Liu Bing left, Li Er continued, "Qingquan, the few days you have disappeared have made me worried."

"Your Majesty, you are worried. Fortunately, I have nothing to do with you." Zhang Nan said.

"Well, this is a blessing in disgrace. But Qingquan, do you know who instructed someone to kidnap you and how you escaped?" Li Er asked. After Li Er finished speaking, he continued, "It's okay, now there are only you and me. If you know, just say it directly that no matter who he is, I will definitely seek justice for you."

Li Er is not only seeking justice for Zhang Nan, but also earning face for himself. Otherwise, the whole world would have to know that the minister he trusted most was kidnapped by the thief for many days.

"Oh, Your Majesty, this is really hard to describe. As for the envoy behind the scenes, I know it." Zhang Nan sighed and then had an idea in his heart.

"Oh? Do you know who is the mastermind behind the scenes? Tell me quickly, I will send troops to get him now. No matter who he is, I must make him pay the price." Li Er hurriedly asked when he heard that Zhang Nan knew who was the mastermind behind the scenes.
