"Sister, who is she?" Su Zizyuan softly said to Su Zixuan. Seeing that the girl in front of him had a cute face, he felt that he wanted to be friends with her.

"She is my sister's friend. She is here to help brother treat his illness."

"I'm not sick, but can she be my friend?" Su Zhaoyuan blinked in anticipation.

Su Zixuan glanced at the expressionless Tao Muyun and felt that it wasn't that simple.

"You called me here to treat this fool?" When Tao Muyun saw Su Zixuan playing house with this fool, he became a bit impatient.

Su Zhe Yuan heard this and was very angry. He knew that he was different from other people, but his servant had told him that this fool was scolding people. He no longer wanted to be friends with this person who scolded him.

"Little sister, let her go, she's not allowed to stay here!" Su Zhe Yuan immediately gave the order to expel the guest.

The gaze with which Su Zixuan looked at Tao Muyun wasn't as gentle as it was before. However, she was speaking the truth after all. Her own family didn't treat her brother as a fool, but as for the others, she didn't care about them.

When Tao Muyun finished speaking and saw Su Zixuan's expression, she realized that she was wrong. However, the words of this fool in front of her made her lose a lot of face. A fool was still a fool. How could he allow others to speak of him?

"Your sister begged me to come and see you. You thought I would come. I won't go, you can't care about me. " Seeing that he didn't like people calling him an idiot, Tao Muyun insisted on calling him that and even purposely called him a few more times, "Fool, fool, you're an idiot."

Su Zixuan wanted to stop him, but she wasn't as quick as Tao Muyun to speak. When Tao Muyun finished speaking, she thought that her brother was going to cause a ruckus with Tao Muyun, which would give her a headache.

Su Zixuan had no choice but to kneel down as well, running a hand along her brother's back as she consoled him in a low voice. However, she didn't see that Su Zaiyuan's crying had stopped. Instead, she cried louder and louder.

This was also the first time Tao Muyun had seen such a scene, seeing this fool squat on the ground and cry so hard that he couldn't catch his breath. She also felt a bit of regret in her heart, thinking that a grand genius doctor disciple like her was actually bullying a fool outside.

Su Zixuan's gaze was a little helpless as she looked at Tao Muyun. She stood on the spot, at a loss as to what to do. The anger in her heart had also disappeared. It was obvious that they were both children, so who could she blame?

Tao Muyun watched for a while and saw that Su Zixuan's comforting words were useless. Afraid that this fool would faint from crying, he reluctantly squatted down as well, "Don't cry, I didn't do it on purpose. I won't call you a fool anymore!"

Hearing Tao Muyun's words, Su Zhe Yuan cried even louder. He was already very loud, but now Tao Muyun felt like his ears were going to go deaf.

He pulled on Su Zhe Yuan's sleeve and was about to get closer to apologize, but someone grabbed his wrist. Before he could even react, he felt a pain on his wrist.

"You .." Tao Muyun pulled her hand over, and when she saw the bite marks on her wrist, she became a little angry. She saw the crying fool standing up, even though he was still sobbing, his face showed an extremely good expression.

"Shoo! I'm asking you to scold me! Let's see if you dare to scold me again in the future!" Su Zaiyuan let Su Zixuan wipe away the tears on his face, and when he spoke, he even started sobbing.

Seeing that this fool had finally stopped crying and was too lazy to bother with him for biting her just now, Tao Muyun did not bother with this fool!

Tao Muyun wanted to see what kind of illness this idiot was suffering from, but he reached out his hand to pull Su Zaiyuan's hand over, scaring Su Zaiyuan into a shiver. Su Zhiyuan thought she wanted to take revenge and bit him back, so he almost immediately flung Tao Muyun's hand away.

This action made Tao Muyun extremely angry. She rolled up her sleeves and wanted to teach Su Zaiyuan a lesson, but Su Zaiyuan knew something was wrong when he saw her attitude. He quickly took three steps back.

However, Tao Muyun didn't have any intentions of letting him go. Every time he retreated a step, Tao Muyun would step forward and in the end, the two of them would run around the yard, up and down, making trouble for each other.

Su Zixuan's initial worry turned into relief, then into amusement. In the end, when she saw that the two of them didn't seem to be tired and didn't want to stop, she almost felt bored.

Su Zixuan didn't have the time to waste in the backyard, watching them make a ruckus. She could only instruct the servants to take good care of her and return to her own courtyard.

After a long while, the two of them didn't have the strength to deal with each other anymore. Only when they stopped to pant did they realize that Su Zixuan had already left.

Tao Muyun dragged his heavy legs and walked over to Su Zhe Yuan's side. He really didn't have any strength left. Seeing Tao Muyun take his hand, he didn't have the strength to break free, so he just let him go.

Tao Muyun calmed down her breathing and focused on Su Zhe Yuan's pulse. She felt the strong and forceful pulse under her fingers, as if it would burst out of her skin at any moment. This was a bit abnormal, and her heart tightened.

She wanted to take a look at Su Zhe Yuan's eyelids and tongue, but when she looked up, Su Zhe Yuan was staring at her, breathing heavily.

Tao Muyun suddenly put down Su Zhe's hand. He felt that he had really gone mad. If he stayed longer with a fool, he would become stupid. She actually went to take someone's pulse after a strenuous exercise!

This matter could not be spread out, otherwise her reputation as a genius doctor's disciple would be ruined.

He quickly walked out of the Dengxuan Hall and stayed away from this fool.

Su Zhe Yuan was left wondering why Tao Muyun didn't bite him.
