There is no account input window, only a password typing window. One machine and one number, real-name system, this is fixed and dead.

After Yang Zhe entered the password, the intranet of the Tiannan College campus was displayed in front of his eyes. This school emblem can only log in to this network, and it cannot take Yang Zhe into other networks, nor can it use hacker technology.

However, as long as there is an Internet, communication will be more convenient than letters and bulletin boards.

Yang Zhe browsed the campus of Tiannan College for a while and found what he was looking for.

"I have a set of idle basic refining tools (full, old) to rent or sell ......"

Yang Zhe immediately replied to the post. "I bought it and came to the door of the Tianyi Department Building to trade. ”

A set of basic refining tools included all the mechanical tools Yang Zhe could think of, including a pocket-sized smelting furnace, which was only five thousand.

This is something that Yang Zhe would not dare to imagine in another world. The refining industry in this world is too developed. This kind of ordinary mechanical equipment, an eighth-grade refiner, can be rubbed out in minutes.

The dormitory is not a very good operation room.

Yang Zhe went to the teacher to ask for leave, and walked out of the school gate.

Outside Tiannan College, there is a city wall.

Outside the city walls, there is the world of the mysterious spirit beasts, the world of war and barbarism. Within the city walls, is a civilized human society.

Between the city walls and the school, there are lush markets, subway stations, and flying fields.

In the street market, there are many students, bustling with people.

Yang Zhe walked into a small hostel and opened the cheapest single room.

Behind closed doors, Yang Zhe opened the suitcase and studied all the refining tools carefully.

Except for the pocket-sized smelting furnace, which Yang Zhe couldn't understand at all, Yang Zhe combined his memories from another world, checked some information with the help of the Tiannan campus network, and after an hour of exploration, he completely understood it.

Yang Zhe first drew a sketch of a sewing machine in his notebook, then calculated the materials he probably needed, made a list, and went out.

Yang Zhe entered a shop that sold minerals and mineral materials, picked and selected, and bought a few pieces of the cheapest thin secret steel, the smallest half-meter secret steel cylinder.

He wanted to buy ready-made gears, but couldn't find them. Yang Zhe had no choice but to buy another pound of centimeter-thick secret steel, ready to polish the gears by himself.

However, Yang Zhe bought a ready-made Xuanling motive. A magical power source similar to the electric motor that Yang Zhe was familiar with in his previous life.

The Mystery Soul Motivation can be driven by the Mystery Spirit Stone, or it can be driven by the user's own infusion of Soul Power.

Yang Zhe's cultivation was low, and he chose to buy the Xuanling Stone.

Xuanling stone is not only a material, but also a currency that is harder than gold. The currency used in the Xuanling world: banknotes issued by various countries, and there are also Xuanling stones.

Xuanling stones are measured in "blocks". The standard size of a piece of Xuanling Stone is: one centimeter in length and width, and three millimeters in thickness.

Such a small piece of Xuanling Stone is sold for as much as 10,000 Yan coins.

The reason why the Xuanling Stone is so expensive. This is because it can not only be used to charge the Xuan Ling motive, but also to charge the human body! This is a biological "battery" that can charge the human body! Wealthy Xuan Ling cultivators use the Xuan Ling Stone to improve their cultivation, and they get twice the result with half the effort.

The money in the bank card is obviously not enough to buy a Xuanling Stone. Yang Zhe decided to sell his armor and sword.

He asked his boss, "Do you accept armor and knives? I mean the expensive ones." ”

"Accept it, do you see the big sword hanging on the wall? It was personally refined by your school's refining master Gu Changyong, and the treasure of my family's town store is worth three million! Classmate, if you have any good things, just bring them! We are doing business on your school's territory, and we will never dare to lose you! I guarantee that our bid must be the highest in the industry. ”

Yang Zhe went back to school and brought his armor and sword. He not only wants to pass this Tianyi master apprenticeship assessment, he also wants to open a garment factory and realize his dream. This requires a big investment. You have to sell it sooner or later, so it's better to sell it early.

"Classmate, your armor, we will bid 180,000 yuan after evaluation, and this sword will be 230,000 gold. Look, can you?"

"Okay!" Yang Zhe nodded. Although the merchant's bid is lower than the true value of the goods, this is also the norm in second-hand transactions. If people don't make money, what kind of business do they do?

"I want two Xuanling Stones and ten large Xuanling Needles. ”

Yang Zhe didn't plan to make the machine needle for the sewing machine, he was afraid that the hardness and toughness he made were not enough, and the large Xuanling needle, which is used to modify the sewing machine needle, is just the right size, and the toughness and hardness are absolutely enough.

The boss smiled: "Classmate, two pieces of Xuanling Stone are two thousand gold coins." Xuanling needles are five coins each, ten fifty. I'll transfer the rest of the money to your bank card?"

The Xuanling Bank Card itself is a Xuanling network connector. However, its Internet access is limited to receiving, transferring, and checking accounts, as well as simple messages.

Yang Zhe took out the Xuanling bank card and accepted the transfer from the other party.

"Classmate, you walk slowly. Come often!"

Yang Zhe went to the restaurant to eat something again, returned to the hotel, and closed the door.

He first picked up a palm-sized delicate knife, which was the Xuanling Cutting Machine. With Xuan Ling energy as the power cutting device, it can cut most metal materials.

Yang Zhe pressed the switch of the cutting machine and stumbled on the secret steel cylinder. Everything is broken. It's pretty sharp and very quiet, only the buzzing sound of a bee.

The polishing machine, which is only the size of a water cup, is also noiseless. The polishing wheel hits the secret steel cylinder, just like the blade hits the fruit, grinding where and where it is polished. If you don't put things on it to polish, it just rotates by itself, and it's completely silent.

Microscopes, tools for measuring accuracy. It looks similar to a magnifying glass, but is much more accurate than a magnifying glass. With it, Yang Zhe can polish gears to the micron level.

The most convenient sewing machine, naturally hand-held, looks similar to a stapler, and it is the same as a stapler. However, the speed is too slow, and it will definitely not meet the requirements of the apprenticeship assessment of Tianyi Master.

Now that he has the Xuanling Motivation and the Xuanling Stone, Yang Zhe decided to build his wireless Xuanling sewing machine based on a small electric sewing machine powered by a battery.

This model is easy to operate, as long as the fabric is pressed under the pin, press the switch, and gently pull the fabric.

Moreover, because the Xuanling motive that Yang Zhe purchased was small enough, he was sure that his Xuanling sewing machine would be the size of a palm.

Now, what Yang Zhe has to do is to polish the frame, core, gear, spool, needle, etc., all in detail.

Yang Zhe wore a microscope, polished it carefully, and was busy for seven or eight hours, and finally finished it.

"This must be the first sewing machine in the Xuanling Continent!" Yang Zhemei thought to himself.

With the sewing machine, Yang Zhe went out to buy cloth for experiments.
