Shen Mang snorted softly, "Doctor Kong, everything has a first come, first served principle. I told Lan Qi that after his leg was injured, I would teach Teacher Yu. If Dr. Kong is free, I will look at the flowers and plants in the yard. I haven't watered it yet, why don't you go take a look?"

Cosine was in a dilemma for a while watching the scene where the two people looked at each other and sparks flew.

He swam from the shallow water to the shore, walked barefoot onto the beach, wiped his body, and put on the grey T-shirt on the chair.

"You two, stop arguing. I've had enough swimming today, and I plan to go back. Next time I'll wait for Lan Qi's leg injury to recover. I'll go to him to learn how to swim."

"Mr. Yu—"

"Cosine—"

Before the two could catch up, Cosine quickly left the beach and walked back to the villa.

As soon as he entered the living room, Cosine found that Lan Qi was sitting on the carpet and playing games. He was holding the PSP in his hand and staring at the screen intently. Cosine came closer, and he didn't even notice it.

"Damn, these stupid teammates are dead again!"

Being beheaded by the enemy, Lan Qi sighed angrily, his legs dangling in mid-air, and he stepped on the carpet a few times in frustration.

Cosine glanced at his freely moving legs.

He patted Lankey on the shoulder.

"Teacher Shang, I have to start the next game. I'll talk about it later."

"Lan Qi, it's me."

Lan Qi raised his eyes to see him, his expression was like a ghost, and he couldn't say anything, "Mr. Yu, you... why did you come back so soon? Aren't you learning to swim?"

Cosine glanced at his left leg, "Didn't you still say that your legs are not good this morning? I see that you seem to be jumping around at the moment, very energetic."

Lan Qi sneered twice, and suddenly held down his right leg in a fake manner, his delicate brows wrinkled, "Oh, after you said that, I suddenly felt that the place where I was bitten by the crab yesterday started to hurt again. ."

Cosine laughed twice.

"I remember you injured your left leg."

Lan Qi smiled embarrassedly, and quickly put his hand on his left leg, "Yes, yes, the left leg was bitten. Look, the bruises on it have not disappeared. I estimate that it will take two days."

Cosine didn't bother to expose him, just asked, "You said last night that the new coach asked me to swim today, who did you find?"

Lan Qi blinked and looked at him with a puzzled expression, "Isn't that Teacher Shen?"

He carefully looked at Cosine's expression, thought for a while, and then asked tentatively, "Could it be that... Doctor Kong also went? No wonder, I said why he went out early in the morning."

"Aren't you going to explain?"

Seeing Cosine's serious face, Lan Qi didn't feel good about joking with him anymore. He scratched his hair and said embarrassedly, "That's right, I promised my idol yesterday, but this morning I met Dr. Kong from upstairs. Come down, I didn't have breakfast at that time, he took another box of butterflies, I couldn't hold back the temptation for a while, so..."

Afraid that Cosine would blame him for hearing it, Lan Qi quickly added, "But I said that the appointment time was this evening. I didn't expect Dr. Kong to go to the beach early in the morning."

It's over, the idol must hate him this time.

"Mr. Yu, I really didn't do it on purpose. I was wrong. Don't blame me, okay?"

Cosine looked at himself pitifully, and sighed helplessly.

Lan Qi has a childlike nature and has many ghost ideas, but his thoughts also change. He was probably in a dilemma between those two people, so he thought of such a compromise.

"Don't do this kind of stupid thing next time. I told them that I will only learn to swim with you in the future. I don't need other coaches."

Lan Qi nodded again and again and handed Cosine the iced orange juice on the table.

"Mr. Yu, you must be tired when you come back from swimming. Let's drink something and add vitamin C."

Cosine glanced at him, took the iced orange juice, unscrewed the bottle cap and took a sip.

Lan Qi didn't know what to think, put down the PSP in his hand, and quietly moved to Cosine's side.

He picked the wheat from his body and asked Cosine in a very low volume, "By the way, Mr. Yu, I haven't seen an idol swim. Is he the type that looks thin in clothes and has flesh in his clothes?"

Cosine didn't know what to recall, and his cheeks were slightly red, "I didn't pay attention to it, I can't remember."

Lan Qi's face was full of disbelief, "No way, you've been swimming with him and haven't seen it yet? The idol must have a very good figure. I think he is usually a walking clothes hanger, and he seems to have muscles on his body."

"What are you two talking about, so happy?"

Shang Zhou's voice came from behind.

"We're talking about what to eat for lunch." Lan Qi quickly answered.

Cosine smiled and put the PSP on the coffee table back into his hand, "You play slowly, I'll go back and read the literature."

In the afternoon, when Cosine was looking at the literature, he suddenly received an email from a foreign journal that he had submitted to before. The other party said that his manuscript had passed the preliminary review, but there were some details that needed to be revised, and he had to revise it within a week.

Cosine was very happy to receive this email and asked him to revise it, indicating that there should not be a problem with subsequent publications. When this paper is published, he will have supporting materials when he subsequently applies for a Ph.D.

He spent the whole afternoon in his room revising his thesis, and when he had finished revising all the inappropriate points pointed out by the magazine, his eyes would be lost.

Closing the laptop, he took off his contact lenses and went to the bathroom to wash his face. As soon as he returned to the room, there was a knock on the door.

"Mr. Yu, it's me. Are you done?"

Cosine opened the door and saw that in addition to Lan Qi, Kong Mingyu and Shen Mang were standing on the corridor.

He was a little puzzled, "I just finished changing the thesis, what's wrong? Is there something wrong with the director team?"

Lan Qi looked around and saw that there was no one else in the corridor, so he whispered, "Mr. Yu, let's go talk first."

Seeing that Lan Qi went straight into his room, Cosine had no choice but to cast doubtful eyes on the two of them.
