Before dawn, there was a knock at the door.

"Who?" Chu Yun stepped forward with a gloomy face, and then opened the door.

"Master, it's me. Old Mr. Wang winked at Chu Yun, and then said mischievously.

"You ask for leave so often, aren't you afraid that the hospital will expel you?" Chu Yun felt that he had a headache.

"Don't worry, master, it won't. Mr. Wang smiled, and then secretly squeezed into the house.

"........." Chu Yun had a black line, but he was really helpless against this old guy.

People patiently ask themselves for knowledge, they can't help but teach, right?

What's more, Mr. Wang is such a highly respected person.

So Chu Yun continued to be patient and taught medical skills to Mr. Wang.

Another day of time rushed by.

Chu Yun had spoken late at night before he knew it.

Mr. Wang asked Chu Yun a question, but Chu Yun did not answer.

"Why is the master asleep again?" Mr. Wang muttered secretly, and then packed his luggage and prepared to leave.

This time, Chu Yun was really asleep, not pretending.

Chu Yun was already so tired that he was about to collapse, and he really didn't know how Old Dean Wang survived.

Obviously, he was already so old, but his body was actually better than Chu Yun.

Maybe this is the potential of the human body, and it is Dean Wang's desire for medical skills.

One night, once again, passed.

"Knock knock...", there was a voice at the door again that made Chu Yun want to scold his mother.

"Master, open the door......... Mr. Wang stood at the door and kept shouting.

"Crunch. Chu Yun opened the door, but his face was gloomy and ugly.

Without further ado, let's get straight to the point.

Chu Yun didn't sleep all night, but Mr. Wang returned with a full load.

"Knock Knock ......"

"Come... ......" Chu Yun opened the door weakly, his face was yellow and thin, and he looked constipated.

"Master, I'm here again!" Mr. Wang smiled.

"I see, let's get back to last night. Chu Yun drooped his eyelids, and then said to Mr. Wang.

For more than a week, Mr. Wang hurried over in the early hours of the morning and then left in the middle of the night.

"Knock knock......" The familiar knock sounded on the door again.

Chu Yun's eyes were bloodshot, and he stood at the door and gritted his teeth fiercely.

"Master, the apprentice is here. Mr. Wang stood outside the door with a longing expression.

Chu Yun angrily took out a large pile of chairs from behind him and piled them directly at the door of the room.

"Master open the door, I'm your apprentice!" Mr. Wang looked anxious, he stood at the door and kept knocking.

"Even if you are my ancestor, I will not be able to open the door for you today!" Chu Yun's face was gloomy, and he said in a very resentful tone.

"Master, open the door, you haven't taught me medical skills today!" Mr. Wang stood at the door, his face anxious.

"I can't teach it anymore, so you can leave quickly. Chu Yun covered his ears, trying to block out the noisy knocking sound.

"Master, you can't do this to me, open the door quickly........." Old Mr. Wang was very persistent, and his persistence made Chu Yun almost collapse.

"Big brother, I was wrong. Hurry up, I beg you, don't come back again!" Chu Yun was almost on the verge of crying.

"Master, open the door quickly, I'm your apprentice Xiao Wang!" Old Dean Wang still kept knocking on the door, knocking on Chu Yun's head dizzy.

Chu Yun stood at the door, he gritted his teeth viciously.

He felt he was wrong.

I shouldn't think of Dean Wang as that kind of respectable person!

This is simply a stinky scoundrel, a stinky rascal, and disrespectful for the old!

Chu Yun felt that he was almost about to collapse, and he squatted down and kept covering his head.

"Master, are you really not going to open the door for the apprentice?" said Dean Wang standing outside the door, his tears in his eyes.

"You hurry up and let me go, don't bother me in the future, I still want to live a few more days!" Chu Yun bit his lip, and then said with an angry face.

"Okay, the apprentice quit first. Dean Wang stood at the door and sighed deeply.

Chu Yun leaned his ear against the door and listened, and after hearing the sound of footsteps at the door, he finally breathed a sigh of relief.

"Crunch. Chu Yun removed all the chairs and stools, and then slowly opened the door.

No sooner had the door opened than an old man with a white beard sneaked in.

This old man who looked like a thief was none other than Dean Wang, and he winked at Chu Yun.

"Master, I haven't seen you for a long time, and I miss you very much. Dean Wang said.

Chu Yun's forehead was bruised, his face was gloomy, and he clenched his fist fiercely.

"Master, what do you want to teach the apprentice today? The apprentice is already a little impatient. Old Dean Wang said to Chu Yun, his tone was full of excitement.

"Come here, I'll whisper to you. Chu Yun stood at the door, and then hooked his index finger at Mr. Wang.

The old gentleman trotted over, and then attached his ear to Chu Yun's mouth.

"I'll teach you today......... How do you get out!" Chu Yun first spoke in a low tone, pretending to be mysterious.

When Mr. Wang listened most seriously, Chu Yun suddenly kicked him in the ass.

Chu Yun barely had much strength in this kick, and he even used the strength to feed.

After these few days, Chu Yun had already discovered that this old guy's deep hiding was not revealed.

So he wasn't worried that his kick would kick Mr. Wang.

I saw that Mr. Wang was kicked by Chu Yun and flew away.

"Bang!"

Mr. Wang sat on the ground, he turned his head and looked at his master with a resentful expression.

"Master, you can't treat the apprentice like this!" Old Dean Wang's voice was like a resentful woman.

"Bang!"

Chu Yun really didn't want to listen to this old guy's nonsense, so he directly slammed the door shut.

"Alas, this master's temper is really short-tempered!" Mr. Wang slowly stood up, patted the dust on his buttocks, and then said with a smile on his face.

"Hurry up and get out of my !!," Chu Yun's voice came from inside.

Among them, Chu Yun used up almost all the breath in his chest.

The sound was like thunder, and Mr. Wang's ears were numb.

"Okay, okay, let's go now. Alas, I really didn't expect that I would be disliked one day. Mr. Wang sighed a little depressedly, and then turned to leave.

His figure slowly vanished, and soon disappeared.

After a while, Chu Yun quietly opened the door a small crack.

Chu Yun stretched out his head and looked left and right.

After confirming that the guy was not nearby, Chu Yun slowly breathed a sigh of relief.

He went back to his bedroom, and his face was depressed.

"I've grown so big, it's the first time I've seen someone more shameless than me!"

"Whew!"
