after returning home, Ye Su went directly to the laboratory. He took a look and found that Lin Zixun and Lin Zixuan were busy in their smaller laboratory, and they couldn't help smiling. The talent of these two people is very good, but there are many talented people in the world, but how many people can achieve something? It's nothing more than effort.

The two sisters, who know how to work hard, can't be better.

Ye Su thought for a moment, opened the door directly and walked in.

They were dressed in white experimental clothes, very simple, but their bodies are very good, even if wearing the experimental clothes, but still very good-looking, let people feel pleasant.

They are focusing on the topic in front of them, but they don't realize that Ye Su has already pushed in.

Ye Su first came to Lin Zixun's side, took a look at Lin Zixun's progress, and could not help nodding. Originally, the topics he had left for the two sisters were probably just Pediatrics for Ye Su, but for them, it was not a simple matter to solve. But at present, Lin Zixun is about to solve the problem completely.

She came to Lin Zixuan's side. At this time, Lin Zixuan was doing an experiment.

Ye Su looked around and frowned slowly. He found that Lin Zixuan had a bad habit. In addition, the operation of the experiment also had some problems.

Ye Su didn't think much about it. She went closer and said, "it's not like this."

"Ah?" Lin Zixuan was stunned for a moment. The sudden voice made her startled. She quickly calmed down. She looked over and saw that it was tutor Ye Su. She could not help but show a happy expression and asked, "what's wrong?"

"There are too many wrong places." Ye Su said faintly, and then, sticking to Lin Zixuan's body from behind, she grasped Lin Zixuan's small hand, so that she could teach with her hands.

Ye Su did a lot of such things in his previous life. He didn't think much about it at this time. In fact, he didn't mean anything else. He didn't want to eat Lin Zixuan's bean curd. He just wanted to teach him better!

But for Lin Zixuan, this is different.

From childhood to adulthood, Lin Zixuan has never had such close contact with a man. Even her father has never been so close to her body!

Ye Su grabs her hands from behind, and she also leans against Ye Su's chest. This feeling makes Lin Zixuan's cheek blush, and she feels a little embarrassed. At the same time, she has some strange feelings. Her mood is slightly complicated, and some are slightly happy. For a while, Lin Zixuan's heart is full of love.

With so many days together, Lin Zixuan can't have no admiration for Ye Su. She is so perfect and handsome. She knows so much. Just like a mountain, she and her sister will be brought into a broader world and see more things. This is more beautiful than prince charming in her dream. It's quite natural to like it secretly.

At this time, the person who is liked, hugs his body from the back and is not happy is strange!

Of course, Lin Zixuan also knows that Ye Su probably didn't mean anything else, but even so, she was very happy!

Lin Zixuan's mouth can not help but show a sweet smile.

Ye Su naturally saw Lin Zixuan's idea and said helplessly, "don't be distracted."

"Well." Lin Zixuan nodded gently.

"Take a close look at what I do, and then write down every step I take. First of all, you should do this," Ye Su said slowly.

Lin Zixuan listened carefully. Ye Su's one-to-one guidance was still so intimate, but it was a rare opportunity. In addition, she decided not to wash her hands tonight! She should have a good aftertaste of Ye Su's feeling of holding her hands!

Not far away, Lin Zixun, who is solving the problem, raised her head and took a look. Suddenly, she saw such a scene, and her eyes widened slightly in surprise.

Sister and tutor such intimate posture, it is a little too close.

In addition, I really envy my sister's ability to speak in front of her tutor. She is very introverted. Even if she wants to talk to Ye Su, she can't speak. She has so many opportunities to speak.

After Ye Su helped Lin Zixuan solve the problem, she came to Lin Zixun's side.

Lin Zixun watched Ye Su come to her side. "Oh," she said, like a frightened bird, and lowered her head in a panic.

Ye Su naturally knows that Lin Zixun's personality is very introverted. In addition to his sister, everyone else is like this. He doesn't care. In addition, such actions make him feel very cute.

He touched Lin Zixun's head and said, "the solution is very good. When you solve all the problems I left for you, come back to me."

"Well," Lin Zixun's voice, like a mosquito, answered."It's good to know." Ye Su still really heard, nodded and said.

Then ye Su turned away and began to do her own business.

After Ye Su left, the two sisters looked at each other. There was no doubt that they understood each other's ideas, but they did not speak

this may be "everything is in silence"!
