Professor Zhang's live broadcast at Huaqing University is vivid and interesting.

He released Chu Han's answers and explained the truth one by one.

The number of live broadcasts exceeded 100 million in a short period of time!

at the same time.

A huge storm has been set off in the academic community of Xia Kingdom!

[Hahaha, the cold man is a great critic! I, he, looked at the answer and instantly understood some ways to solve the problem!]

[Not only domestic problems, but also foreign problems have been solved!]

[The Han Lao is the number one person in the academic world in Xia Kingdom and even the world!]

[I think the last problem will be solved by the cold man soon?]

[To solve the problem, the last problem is more difficult than the other four. The cold man needs to be able to solve it. I will shit on the upside down.]

[Tsk tsk, it's shameful, right? I've taken a screenshot, waiting for you to shit upside down!]

[Upstairs upstairs, don’t embarrass the people of Xia!]

Everyone began to guess his identity as Han Lao.

Most scholars who want to be a fan of the cold-hearted scholars, who want to be brainless, are discovered by people from the Internet Supervision Bureau and have their account banned directly!

This is the respect for the cold man!

Global live broadcast, now people in M ​​and the United States are fucking shocked!

The problem that troubled them was solved like this?

Still a person from Xia Kingdom!

I feel very embarrassed!

When all the bigwigs in the academic world saw these answers, they began to focus on the reverse inference of the question. Next to Chu Han, there was a scholar with golden glasses who took out paper and started writing formulas.

"Doctor-in-law, do you understand what Professor Zhang said?" Ye Xiaoxiao asked curiously.

"Do you understand half or not, where are you?"

"It's okay, I'll do it later."

"Then let's go."

Chu Han stood up, patted the gray on his butt, and pulled Ye Xiaoxiao with one hand.

Ye Xiaoxiao looked at the people around her who were still watching the live broadcast and sighed, "Only in the academic world can you understand how scary Han Lao is! I want to worship Han Lao as my teacher."

Arrive at the milk tea shop.

Ye Xiaoxiao looked around and smiled and said, "The decoration here is very good."

"yes!"

"I'll make milk tea powder first. If you want to solve the problem, there will be paper and pen in the counter drawer."

Chu Han spent half an hour making thirty servings of sweet milk tea powder.

The cost price of a cup of sweet milk tea is five yuan, and the selling price is twenty yuan. After one cup, the net profit is fifteen yuan.

Because most of the people living in Hailan City are high-consumption people, Chu Han is not afraid of not being able to sell it for 20 yuan. After all, the taste is proportional to the price!

When thinking about business, I don’t know how Natsumehan and Ye Wenwen trained.

Chu Han personally opened for two days, and after he gained fame, he left nothing.

Seeing that Chu Han finished his work, Ye Xiaoxiao said, "Do you come and play King of Glory?"

Chu Han smiled and said, "Yes! Come and fight me for 300 rounds!"

The two of them are playing black together.

Time flies quickly, but no one comes.

Chu Han thought for a while and said to himself: "Xiaoxiao, we still have to do promotion. Why don't we put the milk tea shop online and come in and taste it for free, and give a small gift?"

Ye Xiaoxiao frowned, "I feel like it's a loss!"

Chu Han smiled indifferently and said, "Now I don't care about money. The most important thing is to increase the sales volume so that people can know that there is this store in the center of Tianlan."

"Okay, I'll talk to Uncle Fu."

Ye Xiaoxiao called Fu's wife and told her that she would buy some gifts to the store.

Soon, the gifts bought by Uncle Fu were delivered to the store.

Then Uncle Fu sent someone to hand over the flyer.

After receiving the gift, Chu Han posted a message in the Hailan City Circle that those who entered the top 50 sweet milk tea shops can taste a milk tea for free and also give a free exquisite small gift.

A photo of a gift is attached to the topic.

Chu Han put all the gifts on the table and quietly waited for the customers to come.

After more than ten minutes, a cute girl of about sixteen opened the door gently. When she saw Chu Han, she whispered: "Boss, are the milk tea and small gifts here free?"

Chu Han nodded, "Come in and sit down."

"OK."

The girl sat on a chair, put her phone on the table, and looked at the gifts placed there with greed.

After she came back from the hospital, she didn't have much money on her. She happened to find Chu Han's topic in the Hailan City Circle, which contained the gifts she wanted to buy, so she came.

"You need to be iced, at room temperature or hot?"

"It's at room temperature."

Chu Han brewed a cup of sweet milk tea at room temperature and put it in front of the girl.

"Boss, is your store newly opened?"

"Yes, drink it while it's hot first."

The girl nodded, her purpose was to come here for gifts.

Drinking milk tea is by the way.

However, when the milk tea was in the mouth, the girl was stunned!

The girl was a little excited, "It tastes good! It tastes good."

Chu Han sat on the chair, looked at the girl, and smiled slightly.

"Suck ~"

A cup of milk tea was quickly finished by the girl. She licked her lips with unsatisfactory pleasure, and then said, "Boss, have another cup."

Chu Han's mouth twitched.

Do you think my milk tea is boiled water?

Ye Xiaoxiao couldn't help but laugh, "Children, each of us is limited to one cup of milk tea for free."

The girl's face turned red, "Sorry, I forgot, boss, how much does a cup cost?"

"twenty."

"Two...twenty!?"

The girl's hand, who was just about to pay, was stunned.

She thought that this cup of milk tea was at most the same as those milk teas, and the price was around seven or eight yuan.

Unexpectedly, the price increased by two or three times!

Chu Han asked, "Don't you have no money?"

The girl's face turned redder, "I only have ten yuan. I went to the hospital for a checkup before, and the money my mother gave me was almost spent."

Chu Han said: "You are the first customer after our store opened. The price is cut by half and you can buy it for ten yuan."

"Thank you, boss!"

"What flavor is needed this time?"

The girl walked to the counter, scanned the code to pay, and said, "It's going to be hot."

Seeing Chu Han go to make milk tea, Ye Xiaoxiao smiled and said, "Pick whatever gift you want."

The girl nodded and picked out a beautiful bear keychain.

She wants to give this to her best friend.

After the Chu Han milk tea is brewed, it is placed in front of the girl.

“Be careful of hot.”

The girl took a sip and her eyes lit up.

It tastes better than room temperature.
