After class, Tang Runzhi took the initiative to find Ye Luochen again.

"Professor Tang." Ye Luochen smiled.

"Luochen, I have read your last solution manuscript several times, and there are still a few places that I haven't figured out, are you free after school in the afternoon? You might as well come to the old man's house for a light meal, and ask you for advice by the way. ”

"I don't dare to ask for advice. But it's okay to have a meal and chat. ”

"That's great."

Tang Runzhi looked excited, in order to specialize in Ye Luochen's problem-solving steps, he couldn't sleep all night for the places he couldn't understand, Ye Luochen actually agreed to go to his house as a guest, how could Tang Lao not be excited.

At about six o'clock in the afternoon, Ye Luochen bought some gifts after class and returned to his community, he lived in a community with Tang Runzhi, and soon, he found where Tang Lao lived.

When Ye Luochen came to the door, he was about to knock on the door.

I saw a slim girl who also came to the door, took out the key and planned to open the door.

Ye Luochen looked each other up and down, this girl was wearing a uniform, her hair was coiled together, her facial features were marked, her face was fair, and there was a kind of intellectual beauty all over her body.

After seeing the things Ye Luochen was carrying, she glanced at Ye Luochen with her spare eyes, and said with her eyebrows slightly.

"Another one to give a gift. My grandfather won't take your gift. I advise you to go back with your gifts. ”

Ye Luochen just smiled faintly and did not explain.

Seeing Ye Luochen's attitude, the girl's face sank.

With an educational tone, he said coldly.

"I said, why are you like this? Isn't it good to be young, not to follow the right path, and to work honestly? If you want to get a promotion and a raise, why do you have to use gifts? ”

Ye Luochen said helplessly.

"I'm not here to give gifts."

Tang Lan snorted coldly and said.

"Come on, big bags and small bags are coming, why are our families not here to give gifts? There is really something wrong with your character, and after I exposed it, you actually lied in front of me! ”

At this moment, the door opened, and an old man with glasses who looked like a crepe said familiarly.

"Falling dust, are you here? Fast into the house. ”

Then the old man saw Tang Lan behind Ye Luochen again.

"Lan Lan, are you off work?"

With that, Tang Runzhi let Ye Luochen into the house.

Tang Lan looked at her grandfather in surprise, it stands to reason that this kind of gift goes through the back door, grandpa should lose his temper and drive him away, why did he let this guy into the house?

She went into the house for some reason and changed her shoes.

Donald said enthusiastically.

"Luochen, you sit down first, I'll make you tea."

"Don't bother."

"You're a distinguished guest, how can the old man snub you."

Hearing Grandpa's words, Tang Lan's face became even more strange.

What is the origin of this kid, how can he make grandpa pay so much attention!

Could it be that this kid has a big background, and even grandpa doesn't dare to provoke easily?

As soon as Tang Runzhi entered the kitchen, Tang Lan's face changed.

"Didn't you see that you are still a young master? He also said that he was not here to give gifts! Look at your age, do you want to enter our Suhe University to study? ”

"I advise you to die of this heart! Suhe University is a key university directly under the Ministry of Education, if you don't get good grades, even if you come, you won't be able to finish here! I can see a lot of students like you, there are so many every year, and in the end I can't even get a graduation certificate! ”

This Tang Lan's mouth was like a cannon, and he said a lot of words in a row.

Ye Luochen didn't bother to talk nonsense with her, and directly ignored Tang Lan.

"You man! Did you hear me talking to you? Hurry up and get out. Don't ask my grandfather, I've already replied to you for him. ”

Ye Luochen was actually amused by Tang Lan.

This girl, like Donald, is quite upright, but she is a little impulsive, and she doesn't even know what is going on to give people a "lesson".

Just when Tang Lan drove Ye Luochen, Old Man Tang also walked out.

Tang Runzhi hurriedly said.

"Lan Lan is not allowed to be rude! This is your new colleague, Professor Yip. ”

"Colleague? Just like this, he is actually a teacher at Suhe University? Wait, what? You just said he's still a professor? ”

Tang Lan was dumbfounded when she heard this!

Her eyes widened in disbelief!

This young man who looks like he is only in his early twenties is actually a professor?

You know, the title of professor is very difficult to evaluate, and it is already very remarkable to be able to become an associate professor before the age of forty.

And the average professor has to be fifty or sixty years old!

A professor in his twenties couldn't believe that he had killed Tang Lan.

Seeing his granddaughter's surprised face, Tang Runzhi smiled.

"Didn't we have a visiting professor at our school? That's him. ”

"Grandpa, you mean that the manuscript that the two of us have been working on together in the past few days was written by him?"

At this moment, Tang Lan's eyes looking at Ye Luochen had completely changed!

In the past few days, she has been studying with her grandfather Ye Luochen's manuscript to prove Goldbach's conjecture, and the more she researches, the more she admires the "man of God" she has never met.

But who knows, the "fairy" she secretly admires is actually a young man about the same age as herself.

At this moment, Tang Lan's whole person was deeply shocked.

"Grandpa, you...... You're not kidding me, are you? ”

Donald said solemnly.

"You girl, this kind of thing, how can grandpa joke with you?"

Tang Lan turned his head and looked at Ye Luochen in great surprise.

"Is it really you?"

"Okay, stop talking nonsense, let's help grandpa prepare dinner."

Tang Lan was pulled into the kitchen by Tang Runzhi.

"Lan Lan, what do you think of the dust."

Tang Lan lowered her head to chop vegetables, still immersed in the shock just now, and was suddenly asked coldly by her grandfather, she looked up and said in surprise.

"How's that?"

When she saw Donald's ambiguous eyes, Tang Lan immediately understood that what her grandfather was asking was whether she had a good impression of Ye Luochen.

She said hurriedly.

"Grandpa, what did you say!"

"Men should get married, women should get married, you girl is not young, and it is time to think about her life's events."

To be honest, Tang Lan's feelings for Ye Luochen were amazing.

That person obviously looked like a bronze, but he was a king, and this huge contrast made Tang Lan unclear for a while, how he felt about Ye Luochen.

So Tang Lan hurriedly changed the topic.

"Grandpa, don't talk about me. By the way, how are the preparations for the Jiangnan Mathematics Forum next week? ”

When Tang Lao saw that his granddaughter had diverted the topic, he didn't say much, and discussed the forum with his granddaughter.

After the grandfather and grandson chatted for a while, the more Tang Lan thought about it, the more wrong it became.

"How could that kid at such a young age prove the Goldbach conjecture! It must have been used in some way to deceive grandpa. ”

"Hmph, I must debunk his lies later, a person who doesn't learn and has no skills to sneak into the school to be a professor is simply a cancer in the education industry."
