As soon as we met, Xia Xiaoshu discovered that "Purple Lightning" boss Wu from the Internet cafe was a little dejected.

"What's wrong? You're not very emotional, haha..."

"Oh! I felt a little uncomfortable when my son contradicted me."

"Young man! I'm a little angry, don't be as good as him."

"I'll say that, I can't avoid this matter. Sooner or later, I'll have to get angry with him."

"What the hell is it?"

"A house matter."

"Have your son bought a house?"

"No! I said I liked it and wanted me to pay a down payment for him."

"It seems reasonable to listen." Xiao Xia responded with a smile.

Boss Wu and his wife are only sons. They are already in their 25 or 26 years old this year. They have had a girlfriend and are basically at the level of getting married.

Xiao Xia and Xiao Wu met a few times, and they felt that the young man was a little bit floating.

"Oh! My Internet cafe is much less profitable than before. My energy is no longer as good as those two years ago. I can get the down payment, but... the kid actually asked me to help him repay the loan! All the money was given to the couple. I'm old, so why should I take care of the elderly?" Boss Wu complained angrily.

"Boss Wu, this place is not a place to talk. Let's go back to my office to talk!"

"Okay, okay! Sorry, there is no such thing as the world saying about my own little things. I am really..." As he said that, Boss Wu asked Xiao Xia to get in the car.

"Wait for a moment, I'll buy a few tea cups." As he said that, Xiao Xia went to a small department store next to him to buy a small tea set.

Before leaving, the previous purchasers took away almost all the things they could take away, and a customer came to the warehouse, without even a decent tea cup.

Xiao Xia usually drinks tea with rice bowls.

When they arrived at the warehouse door, Xiao Xia opened the door and called Boss Wu to park the car in the yard.

Boss Wu seemed a little restless, and when he was not careful, he almost tripped by a pole.

"Hey?! I said Xiao Xia, who is this? Standing such a pole here? How in the trouble!" Boss Wu asked in confusion.

"I stood that rod, and I measured the data when I was fine."

"Is that so? What's the use of testing that thing?" Boss Wu asked casually.

"I am a man, and I am used to measuring the local longitude, latitude and other places wherever I go."

"Ah?! You still have this habit! I really admire you! What's the use of measuring that thing? Once you position your phone, you'll find it all on the Internet? It's still very accurate!" When I heard the tone of speaking, it seemed that Boss Wu also had the habit of using latitude and longitude to figure things out.

"That's different. The specific calculation process is more important and can provide me with many parameter details."

"How do you measure this thing?"

"When you are fine, draw the shadow of this rod and make a record. The more you repeat it, the more accurate the measurement is. Then take the data of the shortest moment of the shadow and determine the direction north." Xiao Xia explained with a smile, and gestured a few times with a small branch.

"What's the matter?" Boss Wu is also a person who likes to use his brains.

"Summarize the relevant measurement data of the shortest moment of the shadow, take the average value of the shadow length and the rod length, and then use the three-solution function to calculate the elevation angle of the sun."

"It sounds so complicated. Can you make it simple?"

"Let me say that, after calculating the elevation angle of the sun, refer to the time periods of the spring equinox, autumn equinox, summer solstice, and winter solstice, we measure the number of dates of the time period. With the help of triangle interpolation, we can calculate the specific data of the direct sun point of the day. Once these data are summarized, the latitude of the place will be calculated."

"It sounds like a big head, what about longitude?"

"After determining the direction of the north, find the direction of the south. When you have nothing to do, record the specific time when the sunlight passes through the direction of the south, and then compare it with the known longitude time, and calculate it a little, and the longitude will be calculated."

"My God, it's so complicated! A few days ago, I told my lover that Xiao Xia is a city man who lives in such a remote countryside and lives in a separate courtyard. At first glance, there is not even a neighbor around him, so he must not be lonely! Now I understand, you are busy doing this all day long."

"Hahaha... You can say that well. At a young age, I have to find some serious things to do."

The two walked and chatted. When they returned to the office, Xiaoxia adjusted the fire a little more vigorously, boiled water and made tea.

"Xiao Xia, did that Mr. Shang come to you a few days ago?"

Xiao Xia nodded. In his opinion, this was the purpose of Boss Wu's trip.

"Have he...has he mentioned to you that he invested in my Internet cafe?"

"Without mentioning a word, I talked about it for a while and then left."

"Then... can you ask me for help? I'll just look for him, and I'll send me away if I'm afraid he'll beat me up." Boss Wu said in embarrassment.

"Boss Wu, in my opinion, as long as he doesn't take the initiative to speak, you ask or I ask, it doesn't matter."

"Then... let it go?" I felt that I had been working in vain for a long time, and Boss Wu felt a little unwilling.

"No, let him take the initiative to negotiate with us. In this way, we will take the initiative. Otherwise, it would be embarrassing to say that he would just say it casually that day, just pretend to be a joke. Is that right?"

"Will he take the initiative to look for us? Can you?" Boss Wu was a little unbelievable.

"To be honest, I'm very short of money on hand, and it's hard to do anything to do. I want to make some money, too." Xiao Xia told the truth.

"Is that true? Then what are your specific plans?"

"I plan to design a game involving mathematics learning, which is a game that is very close to the daily learning of middle school students. I have thought of the name, "A fun number journey."

"Ah?! This... seems to be out of touch with me, right? I know a little about game development. I can't reach anyone like me!"

"No, this game is more appropriate to promote in Internet cafes, and it also has a certain degree of public welfare, which is of great benefit to children's learning mathematics!"

"Is that so? How much does it cost?"

"The money matter is up to Shang Yixi to consider; you are responsible for promoting and promoting in Internet cafes, and leave the rest to me."

"This... does it sound a bit unreliable?" Boss Wu was a little bit skeptical.

"Can't trust me? Or can't trust Mr. Shang?"

"That's not, mainly... I feel like it's almost the same as if it's me or not... Haha..." Boss Wu is a little businessman after all, and his mind is not slow at all in this regard.

"How could it be?! Do you know how much it costs to advertise casually now? That's a considerable amount."

"Even if your educational and entertaining game is designed, Mr. Shang will definitely talk to us about investment?"

"pretty close."

"Is that so? What do I need to do?"

"You usually talk to middle school students in Internet cafes, especially those children from the third year of junior high school and senior high school graduation classes. Let's hear what their worries and wishes they have in the specific mathematics learning process. The more detailed the records you record, the more targeted I design it here."

"No problem! This is all about me. Then... what else can I do?"

"Let me go back and collect some gamepads. The more complete the types, the better. No matter what kind of gamepads, it will be brought to me. Even if it is an gamepad that has been eliminated many years ago, I want that kind of gamepad. That kind of gamepad is more meaningful to us."

"No problem! That's it? What else can I help?"

"That's all for the time being. I'll look back and wait until I remember it, and call you."

"Okay! I'll go and prepare now." As he said that, he didn't bother to drink tea, Boss Wu said goodbye.

Looking at Boss Wu's hurried back, Xia Xiao shook his head several times and sighed in his heart: "Oh! I deserve this father..."
