I don't know how long I waited, but after the senior sister placed all the classmates, she came out of the door.

Gu Jingyu stood alone at the door, he was not the male protagonist, and naturally he would not be like the male protagonist, carrying a troublesome physique with him.

At the door, I waited quietly for the senior sister to come out, while checking the ingredients updated by the shopping network.

"Classmate Gu, I'll take you to upgrade the light brain now." As soon as the senior sister came out, she saw Gu Jingyu sitting obediently on the side, her long hair hadn't been cut for a while, and she looked a little well-behaved when it hung down.

After Gu Jingyu raised her head, the senior sister's inner thoughts disappeared in an instant.

Where is this obedient, this is simply a noble son.

Suddenly, I felt that the ancient earth I saw on the Internet had a face.

Gu Jingyu looked at the senior sister strangely, he could feel that the emotions on this senior sister had changed a lot, and he didn't know what the reason was.

"By the way, upgrading the Light Brain costs 50,000 Star Coins. You can also choose to owe it first, and there will be many opportunities to earn money after enrollment, and you can pay it back when the time comes. Your current light brain is too inconvenient in school. ”

The senior sister considered that the clothes Gu Jingyu was wearing didn't look like a rich person, and he had just spent a lot of money on accommodation, so she was afraid that he would not have enough money to upgrade.

As if he was afraid that he would misunderstand, he continued: "Upgrades in the school will be much more affordable than outside, and ordinary upgrades will cost a full 100,000 outside, and the school has already discounted a lot." ”

Gu Jingyu nodded, he was thinking about whether to take credit, the money on him was enough to pay for the upgrade of the light brain, but after using it, there were too many places to spend money in this school, and it would not be his willingness to put himself in a state of embarrassment when the time came.

"Senior sister, if I pay on credit, do I need to pay interest?" Gu Jingyu asked.

The senior sister paused for a moment, and she didn't feel strange when she thought about it: "A part of the interest will be charged, but this interest is very small." However, if there is a request for credit, you need to work in the cafeteria for three days a month. ”

Most of the people in this school are either rich or expensive, and a few people have very good grades, plus the principal of the school is an unusual person, and there is no need for canteen robots in the canteen, and they work for these poor students.

And if you owe money at school, you will be required to work in the cafeteria at least three days a month, and of course the salary is also very considerable.

When Gu Jingyu heard this, he decisively crossed out the option of credit.

Not long after the two of them walked, they arrived at a lobby, which looked a bit like the Hui style building of the ancient earth from the outside, and when they walked in, they could feel a full sense of science and technology.

As soon as I entered, a teacher sat on the side, holding a glass of water in his hand and carefully putting a little leaf into it.

Gu Jingyu: ......

What is this operation?

After seeing it, the senior sister said helplessly: "Teacher Liu, are you fiddling with these things again?" What's so good about this thing. ”

The teacher was obviously a little indignant, and said menacingly: "This is not anything else, this is the favorite tea of those literati and scholars on the ancient earth. ”

Gu Jingyu was instantly shocked by his words, is this tea?

Turning his head to look at the handful of fresh leaves, looking at the teacher's intoxicated appearance, he suddenly felt that his three views had been impacted.

Good night, good night!
