My skill tree increases every day.

"How is it?"

Lin Yu handed the folder in his hand to Li Mai.

In fact, the workload of calling on you is not as great as Lin Yu imagined.

Because Li Mai's preparations were very thorough and the forms were well-prepared, all Lin Yu had to do was fill in the forms according to what the old men and women said.

Most people were quite cooperative; after all, it's nice to have someone to chat with when you're bored while working.

A small number of people who were indifferent to Lin Yu were willing to share their knowledge and information with him as long as Lin Yu made a small purchase of some of the small items they were making.

There have been no more situations like the old lady selling shoe insoles who needed to keep recharging her account.

Sure enough, Wu Jing's place is the real deal!

What Lin Yu didn't expect was that Li Mai actually managed to pull some strings at the school and get them a letter of introduction.

Lin Yu was somewhat surprised when Li Mai said that she had already contacted the Guzhen Neighborhood Committee via email.

Lin Yu was a bit shocked. When he went back to his old neighborhood committee, people there barely paid him any attention. But here he experienced what it meant to serve the people.

It is a university directly under the Ministry of Construction and the Ministry of Education. Although it is not a "double first-class" university, it still has some prestige.

The village committee's reception room allowed Lin Yu to drink mineral water for half an hour.

Unfortunately, it's not from Baishui Mountain.

It's a bit harsh on the throat.

"Senior, you have such connections?"

Lin Yu stood there, a look of joy and humility on his face, his lips moving but no sound coming out. His attitude finally became respectful, and he clearly called out:

"Senior!..."

Li Mai seemed to shiver...

"Don't do that."

Lin Yu's appearance made Li Mai laugh.

Li Mai chuckled and lightly patted Lin Yu's shoulder with the folder.

Lin Yu chuckled and stopped joking.

Lin Yu admired this senior's abilities.

"Lin Yu," Li Mai flipped through the folder in her hand, carefully examining Lin Yu's handwriting, "Could you sign your name here?

Lin Yu took the folder. On the last page, there was a special signature area, where Li Mai had already signed her name.

"Okay, coming right away."

Li Mai was indeed very serious about these tasks. He not only recorded and photographed each interview with an elderly person, but also left his signature at the end.

How formal!

Lin Yu sighed and signed his name in the empty space below Li Mai's name.

Although Lin Yu's handwriting wasn't very good, and it wasn't exactly beautiful, it was only passable. But Lin Yu wasn't bragging; his signature was actually quite skillful, showing that he had put in some effort.

Before Lin Yu even started school, his family began teaching him to read. The first character he learned to recognize was his own name, and the first character he learned to write was also his own name.

Furthermore, Lin Yu's mother specially found these two characters in rubbings and then designed them by combining them.

Lin Yu started practicing this signature style before he even started elementary school.

Lin Yu's former Chinese teacher once joked that if Lin Yu could write every character as well as his signature, he would be quite competitive in calligraphy competitions.

Unfortunately, all Lin Yu has to offer is his autograph.

Leaving aside his signature, Lin Yu's calligraphy can only be considered mediocre at best.

"Okay, senior."

Lin Yu handed the folder back to Li Mai.

Li Mai took the document, examined it carefully, looked at it over and over again for a long time, then took out her phone to look at it, a smile appearing on her face.

at last……

Li Mai looked up at Lin Yu and remained silent for a long time.

"Um, what's wrong, senior?"

Lin Yu felt a little uneasy under Li Mai's gaze, wondering what she was thinking.

Could it be that they think my record is not good enough?

"It's alright, let's go back."

"it is good."

Lin Yu breathed a sigh of relief.

Having completed their task for the day, the two began to walk back.

The two walked side by side in the sunlight along the alley they had come from. When they passed the old woman who made shoe insoles, she was still sitting on the doorstep, with a basket of shoe insoles piled up beside her.

"Let's go? Aren't you going to buy two more?"

The old lady's Mandarin was already quite standard; clearly, the three ten-yuan top-ups Lin Yu made had significantly improved her Mandarin.

Lin Yu didn't want to talk to the old lady, so he just kept his head down and walked forward. Li Mai, on the other hand, seemed very happy and turned around to greet the old lady.

Perhaps it's because something has come to an end.

Goodbye, Grandma.

Li Mai waved his hand, not taking a single insole with him.

The old lady pursed her lips; she hadn't received a single penny.

The two continued walking, and as noon approached, the houses in the alley finally became more lively, and there was a sense of everyday life.

"Senior, is there something good that's happened?"

"Hmm? Why do you say that?"

"Because the senior looked very happy."

"Is it...that obvious?"

"yes."

"Perhaps it's because something has finally come to an end."

Li Mai smiled at Lin Yu.

Would you really be happy to finish your homework? Isn't that just like a primary school student?

Is he really that innocent?

Lin Yu looked at Li Mai. Li Mai had a soft face with chubby cheeks, and with a pair of round-framed glasses, she really had a cute baby face.

Lin Yu suddenly thought of something: if that's the case, then Li Mai is...

Is she the baby-faced type?

Lin Yu once again found it difficult to control his gaze, which was unconsciously drawn to certain celestial bodies with strong gravitational pull.

Hawking was right.

Black holes are real, and they really can attract light!

Lin Yu thought about it and felt that Li Mai was not the kind of person who would be happy because she had finished her homework.

But he couldn't quite put his finger on it.

Once on the subway, it was crowded, so the two of them didn't have a chance to sit together and had to sit separately.

After Li Mai sat down, she took out the folder from her bag, browsed through its contents, and finally turned to the last page, looking at the two signatures on the white paper.

The two signatures were placed one above the other, with Li Mai's signature on top and Lin Yu's signature on the bottom.

After looking at it for a while, Li Mai closed the folder and carefully put it into her canvas bag.

I opened my phone and brought up a photo in my album. It was a slightly yellowed, old piece of paper.

There were many scribbles and corrections on the paper.

However, it is still easy to tell that it belongs to the title page of a mathematics textbook.

Below the large title "Mathematics," there are still two names, arranged one above the other.

Li Mai's name is at the bottom, and above her name is a flamboyant signature.

Although the strokes of the name above are a bit immature, it is clear from the shape, structure and penmanship that it was written by the same person.

Although the characters are elegant, their shapes and meanings are easily discernible.

Those were clearly two specially designed characters.
