I confessed my love to the school beauty but was rejected. My school beauty's best friend propo

Corridor.

Everyone was shocked when they saw the old professor of advanced mathematics.

As a result, Lin Yu shouted directly: "I'll do it!"

They were all stunned. What happened to Lin Yu?

The old professor also smiled and looked at Lin Yu: "Lin Yu, why are you here? Come on."

Lin Yu walked over directly: "Professor, your pile of folders is too heavy, let me help you carry it."

Everyone: "......................................................."

The professor did have a pile of folders in his hand, but they didn't look very heavy.

They just thought Lin Yu was really cruel and delivered it to the door in person.

Advanced mathematics in college is very difficult. Everyone was a little scared when they saw the old professor of advanced mathematics.

Only Lin Yu was so brave.

The old professor smiled: "Okay, Lin Yu, I just happened to find you for something."

Wang Jun, Xu Qing, everyone: "Σ(ﾟ∀ﾟﾉ)ﾉ"

"Fuck!"

A sheep in the tiger's mouth, a classic sheep in the tiger's mouth! Lin Yu delivered himself to the door!

You are worthy of it, Lin Yu!

Only Leng Qingxue felt that there must be a reason for this.

Because she knew that because Lin Yu had a good talent for advanced mathematics, the old professor liked Lin Yu very much.

Lin Yu looked directly at Xuexue: "Xuexue, you go first, no need to wait for me."

Then he helped the old professor take the folder and followed the old professor.

Everyone left after seeing this.

.......................................................................

Lin Yu put the folder on the old professor's desk.

The old professor smiled and looked at Lin Yu: "Lin Yu, the advanced mathematics problem you solved last time was very good."

"Even I have to praise you."

The last time Lin Yu solved the difficult problem at the speed of light, it really surprised the old professor.

Lin Yu said politely: "Professor, I just want to challenge myself today."

The old professor was stunned: "Huh?"

"Professor, do you have any difficult questions? I want to try to answer them."

When the old teacher heard this, his smile became even stronger: "Ruzi is teachable, Ruzi is teachable."

"I really have one."

As he said, the old professor took out a latest high-level math problem, which none of his graduate students could answer.

"Come on, I'll give you one morning. With your level, you should be able to answer it in one morning."

Lin Yu took the problem, "Okay, professor, I'll try."

The corners of his mouth rose slightly. He didn't need one morning, one hour was enough.

Then.

The old teacher went to the lecture hall, and Lin Yu stayed here to answer the questions.

.....................................................................

The first question was spatial analytic geometry, which Lin Yu solved in half an hour, and the second question was ordinary differential equations, which Lin Yu also solved in half an hour.

After Lin Yu solved the problem, he didn't rush back.

He now has plenty of time to prepare a gift for Xuexue.

Yes, all this is within his calculations.

Lin Yu has already thought of what gift to give Xuexue, that is, a hand-knitted scarf!

Lin Yu directly said in his mind: "System, search for scarf materials."

[Host, super warm and dustproof wool, 100 points]

[Do you want to buy it?]

"Yes."

Then, a bunch of pink wool balls for knitting scarves appeared in Lin Yu's system space.

Seeing that the materials were ready, Lin Yu continued to say in his mind: "System, buy the master-level solution for knitting scarves."

[Master-level solution for knitting scarves, 100 points]

"Buy!"

[Purchased]

Lin Yu did it in one go, "System, use the master-level solution for knitting scarves."

[Used]

"Buzz." Lin Yu's mind instantly flooded with countless knowledge about knitting scarves, even knitting sweaters, and the selection of sweater materials.

He is now a master of knitting scarves, and knitting scarves and sweaters is easy for him.

......................................................................................

On the other side, Leng Qingxue was wondering where her little Yu'er had gone.

Where is her little Yu'er!

"(*ﾟﾛﾟ)!!"

It's been an hour since I last saw her!

Lin Yu was knitting a scarf for Xuexue carefully.

The pink scarf that had taken shape was already in Lin Yu's hands. He held three knitting needles in each hand and knitted the scarf at the speed of light.Scarf.

Lin Yu used his master-level art design skills to design two Q-version character portraits.

These are the cute character portraits of Lin Yu and Leng Qingxue, which look very cute and are also woven on the scarf.

One hour later.

Lin Yu still had a small corner of the scarf to weave. At this time, the old professor came back during his break.

As soon as he opened the door, he saw Lin Yu weaving a scarf.

Old professor: "Σ(ﾟ∀ﾟﾉ)ﾉ"

Lin Yu was stunned when he heard the noise: "Σ(ŎдŎ|||)ﾉﾉ"

"Fuck!"
