"upgrade!"

"Ding! System upgrade in progress!"

"Ding! Upgrade complete. The system has returned four times the funds, awarded one lottery draw, and 3 free attribute points!"

With a thought, Gao Yan brought up the system panel.

When he saw the next upgrade experience requirement, he frowned and asked the system in his mind, "System, how come the upgrade experience requirement is so high?"

It takes 50,000 experience points to go from level 3 to level 4.

However, the experience required to upgrade from level 4 to level 5 has increased to 1 million.

System: "The first three upgrades are a newbie protection period. After completing three upgrades, the newbie protection period will be lifted, and the difficulty of upgrading will increase!"

"So that's how it is!"

Gao Yan understood and didn't say anything more, after all, he had also gained a lot of benefits from the system.

After all, the system had already refunded him for the 13 phones.

After the remaining two units are sold, there will be a 4x return, resulting in another 100 yuan in income.

I lost money after deducting the cost of buying the phone.

Pure profit of [amount missing].

Just then.

Four more people came into the store.

One was a classmate, while the other three were from the same department.

All four of them came to buy mobile phones.

But now only one remains.

Gao Yan sold one of the machines to the boy in his class, and the other three decided what to do with the remaining one.

This made the boy in the class very happy.

Praise your insightful words.

After all 15 phones were sold out, people came to the milk tea shop to inquire, including classmates and students from other classes.

So Gao Yan quickly sent a message in the class group saying that the phones were sold out.

soon.

The news that Gao Yan was selling mobile phones quickly spread throughout the class.

Those who bought the phone proudly showed it off in the group chat.

Those who didn't manage to buy it felt great regret.

Some classmates also messaged Gao Yan privately on WeChat, asking if he could still get a phone.

Gao Yan didn't rule it out completely, only saying that he wasn't sure. He added that if his relative wanted to sell the phone at a low price, he would definitely notify everyone in the class immediately.

The upgrade experience has already reached 1 million. If I continue selling phones, I need to sell 250 more to accumulate enough upgrade experience.

Therefore, Gao Yan is also considering whether to continue using this method.
