When Liu Yan returned to the store, he saw Su Yun sitting at the door with one hand on her chin as she stared blankly outside. Her pretty face had a mature charm and her posture was so quiet and elegant that it made one think in their heart, "What is she thinking?"

"What?" Is he trying to seduce customers to spend their money here? " Liu Yan chuckled as he sat before her.

Su Yun rolled her eyes and stared at him: "I'm trying to figure out what you're up to, just go out with Liu Hao every few days, I'm warning you, although Liu Hao isn't a bad person, but his boss isn't a good person, you better not learn bad things from him."

"Sister Yun, don't worry. I'm treating a friend of Boss Liu Hao's. I'll be there every afternoon."

"Are all the rich people nowadays so easily sick? If I don't go to the main hospital, why would I have to look for you to treat me? " Su Yun asked in bewilderment.

"Who asked me to have outstanding medical skills?" Liu Yan shrugged his shoulders and revealed a complacent smile.

In her impression, Liu Yan was a Chinese doctor, and she felt that he was of a certain level. However, in terms of medical skills, there were so many A-level hospitals in the big cities, and those rich people chose him to treat them. This was something she couldn't understand.

Jiang Jianguo's treatment of his illness was on the right track. Liu Yan went out to the Medicinal Herbs Market to buy some medicinal herbs. After returning, he began to sort them out.

The next day, Liu Yan finished cooking Jiang Jianguo's medicinal meal in the morning. After finishing his work at noon, Yang Shan came over. He wore a black trench coat, and his expression was cold, as if he didn't want any strangers to enter.

"Wait a moment!" Liu Yan shouted and went into the kitchen to pack up the medicinal food. Then, he walked out.

At this time, there were still many customers eating in the restaurant. Yang Shan was standing alone in the middle of the restaurant, and his tall and skinny figure was very eye-catching.

"Next time, just wait outside. Don't disturb my business." Liu Yan said bluntly as he walked past Zhang Xuan.

Yang Shan just coldly looked at him, but didn't say anything.

They walked all the way to Jiang Jianguo's luxurious manor. Before they entered the house, Yang Shan was still searching Jiang Jianguo's body. His phone and watch were also taken off.

Seeing Jiang Jianguo, he did look a lot better than yesterday. However, his entire body was still swollen. After half an hour of treatment, Liu Yan asked him to drink the medicinal food he had prepared.

Yang Shan took another jar and carried it in, saying in a low voice, "Yes."

"Alright." Jiang Jianguo smiled.

Liu Yan felt a little strange. The soup seemed to have dwindled a lot, but he did not pay it much heed. After repeatedly warning Jiang Jianguo to rest well, Yang Shan brought him out of the room.

Arriving at the living room on the first floor, Liu Yan saw two more puppies in the corner of the living room. Each of them had a plate in front of them as they drank the soup with relish.

Because he was very familiar with the smell they emitted, his heart suddenly chilled. He hadn't thought that Jiang Jianguo would be so cautious to the point that even food had to be tested with the little milk dog's poison.

After two days of treatment, in the evening, as per their agreement, Liu Yan called Squadron Leader Zhou and told him about his two days of observation.

After hearing that, Captain Zhou said in a heavy tone: "We have secretly observed Jiang Jianguo for a long time, but he has not left our house for nearly eight months. He has no children, and did not go out during New Year's or receive any visitors, so he can be considered to be living an isolated life, but I did not expect him to be so cautious in his own home."

Captain Zhou smiled lightly and said: "It's fine, you continue treating him, you will eventually find a chance. If it really doesn't work, we will give you a chance."

"Alright, I will fully cooperate with your work." Liu Yan sucked in a deep breath. Simply putting a bug in his ear made him feel an exceptionally difficult situation to deal with.

After treating Jiang Jianguo for a week in succession, Liu Yan would make an excuse to sit down and secretly observe the situation in Jiang Jianguo's bedroom. He was not sure if there were any cameras in the room, but he had already found a place to place his bugs.

Over the past week, Jiang Jianguo's condition had clearly improved. The swelling on his body had eased up by quite a bit, and his body had become more powerful as well. He did not feel any discomfort even after walking normally for more than ten minutes.

That night, after Liu Yan's shop closed for the night, he invited Liu Hao out to eat supper at a roadside stall by the river.

After ordering, he looked around and said in a low voice, "I feel that I can find an opportunity to place a bug. Right now, Yangshan and Jiang Jianguo are very lax with me, and during my treatment of Jiang Jianguo, Yangshan went out from time to time. Now, I have a chance, every time I bring a medicinal cuisine over, Yangshan will let the dog test it. After I give it to Jiang Jianguo, I will let him bring the medicinal cuisine up. When he leaves, I will play the bug."

Liu Hao scanned the surroundings and said calmly, "The watches have all been detained by Yang Shan, so you must carry the bugs with you."

"It's easy to find!" Liu Yan was taken aback.

"Hide it in your mouth." Liu Hao grinned, and a coin appeared in his hand. He threw it into the innermost area, opened his mouth, and then said normally: "A bug is even smaller than this coin. Practice it for a bit, then pretend to yawn, take it out, hide it in your hand, and take the opportunity to put it away."

Liu Yan widened his eyes and stuffed a coin into his mouth. From the outside, he didn't seem to have changed at all. Furthermore, Liu Hao's voice was no different from before.

Liu Hao immediately grabbed the coin, flushed it with water, and threw it to Liu Yan. Then, he began to teach him how to hide the coin in his mouth.

This was a very skillful action. It was something that Liu Yan could easily learn with the aid of his teeth and tongue. However, when he opened his mouth to speak, he found it somewhat unnatural, and needed a skillful process.

"Spit it out! Help me treat a patient! " Suddenly, Liu Hao said something to Liu Yan. At the same time, he stretched out his hand: "Hurry!"

Liu Yan was surprised. Although his tone was urgent, his expression was calm. Liu Yan didn't doubt him. He immediately spat out a coin and extended his hand to feel Liu Hao's pulse.

After observing his pulse for less than two seconds, Liu Yan heard the sound of footsteps from behind. It seemed that there wasn't just one person.

"You would eat at a roadside stall?" Liu Hao raised his head, revealing a smile as he looked behind Liu Yan. However, the other party didn't say anything.

Sensing Liu Hao's nervousness just now, Liu Yan didn't dare to turn around. He could only continue to feel Liu Hao's pulse. Liu Hao was very healthy, but he always felt like he needed to say something. After all, this was in coordination with Liu Hao's acting.

"There's nothing wrong with that. It's just that you need to have less lung heat, smoke less, or drink more water when you're done smoking. If you don't find it troublesome, I can prescribe a pill for you and drink more to rid you of the poison in your lungs." Liu Yan chuckled before releasing his hand. Only then did he turn around to take a look.

The person standing behind him was Yang Shan, and he was also wearing a black trench coat. Behind him stood two tall men. His expression was still very cold.

"What are you two doing here?" Yang Shan's eyes were like sharp swords, sweeping over the two of them.

"Come out for a midnight snack and have Dr. Liu take a look at my illness. "Brother Shan, your control is a little broad ~" Liu Hao looked at Yang Shan with a fake smile.

"Mister Jiang might need to go out tomorrow. Doctor Liu, go to bed early tonight. Prepare to go out with Mister Jiang tomorrow." Yang Shan snorted lightly and then left with his men. Under the gaze of the two, they entered a clubhouse across the road.

"Huff …" Liu Yan let out a breath with a face full of fear, "Brother Hao, you scared me to death. The two of us knew each other since a long time ago. Yang Shan definitely knows this. Even if he came, there's no need to be so cautious, right?"

Liu Hao smiled: "Yang Shan is Jiang Jianguo's loyal dog. From his point of view, if he suddenly saw us sitting here in the middle of the night, he would definitely suspect something. The reason why I asked you to treat me is to divert his attention.

Liu Yan tilted his head as he thought about it. It seemed that this was indeed the case.

"Jiang Jianguo rarely goes out. Even if he does, he goes to the river opposite his house to fish. He doesn't even need you to accompany him. It seems like he wants to go far away!" Liu Hao frowned.

"Could it be to discuss business with Eighth Lord?" Liu Yan asked nervously. He had been treating Jiang Jianguo for a week and had been doing well the entire time. This sudden action had caught him off guard.

"If that's the case, the Eighth Lord will definitely inform me in advance." Liu Hao shook his head. His expression became more and more serious. "He must be out of the house to take you with him. That must be something important and may have something to do with his business."

"Then what should I do tomorrow?" Liu Yan instantly panicked.

"Don't worry, just be a good doctor and don't act rashly."

"Are we still going to put the bug on tomorrow?" Liu Yan lowered his voice.

"Do as you see fit. Jiang Jianguo is going out, so Yang Shan will definitely prepare for it. When the time comes, you may have the chance."

Liu Yan slowly nodded his head.

The next day, just as Liu Yan and Yang Xiaohu bought the ingredients and sent them back to the restaurant, Yang Shan called.

"Come to Mister Jiang's house at ten."

With this tone, there was no room for discussion at all. Liu Yan felt displeased upon hearing this, but there was nothing he could do about it.

"I'll be there on time."

After making some preparations, Liu Yan came to Su Yun's side and said guiltily, "Sister Yun, I'm going out today. I don't know when I'll be back, so I'll be troubling you and Xiao Hu with the matter in the shop."

Su Yun smiled, "Go back to your work. The treatment is more important. I've already contacted Lil 'Ye, she'll be coming in the afternoon."

Lil 'Ye was one of Su Yun's previous employees. Before this, she had been taking care of her father who was sick at home. Liu Yan listened and nodded, "Then I'll come back tonight to talk to her."

"Yes."

After cleaning up, Liu Yan took the silver needle case with him and hailed a taxi to Jiang Jianguo's home.
