Chapter 43 Autonomous Trading Platforms
The forehead of first-level star warlock Xiang Xin shone in the sun. She squinted her eyes slightly and still looked down at Cheng Jinzhou. There were more than a dozen scattered materials piled on the square table in front of her, all of which were neat and standard parts.

The hard work of the past few days has paid off, and Cheng Jinzhou has become more and more confident. He walked to the square table with his hands behind his back and said ****ly: "Do you remember how to make an ordinary balance?"

"Of course I will." Xiang Xin still had a twist at the end of her sentence. She has studied astrology for more than ten years, and making objects is also one of the categories.

Cheng Jinzhou didn't seem to hear the irony, he snapped his fingers and said, "Make one."

As he said that, he sat on the big chair on one side.

The status of the two seemed to be reversed in an instant. Xiang Xin opened his eyes wide and frowned: "Are you going to regret it now?"

"Can you make a balance with an accuracy of 0.1 grams?" Cheng Jinzhou said with a flat expression: "You don't bother to make ordinary balances, but you can't make high-precision ones. At this time, if you want to steal a teacher, you have to have a balance." Pay, let’s make the balance first.”

Xiang Xin's eyes were full of anger, and he gave a heavy "hum", surprisingly did not resist, grabbed the materials on the table and started to make.Cheng Jinzhou's theory was so serious earlier, she really wanted to take a look.Together with astrology, even if it is long-sightedness, it can also benefit a lot. She will not give up such an opportunity—on this point, Cheng Jinzhou is very accurate.

However, from Xiang Xin's expression like a rabbit being shocked by electric shock, it can be seen that if Cheng Jinzhou's production fails, the end must be miserable.

Cheng Jinzhou watched carefully from the side, and he also wanted to understand the level of craftsmanship in this era.

I saw that Xiang Xin first took out a long straight piece of wood, carved a mark on the center, then put it in his hand, swayed it from side to side until the two sides were balanced, then used a knife to remember the center of gravity, and then turned to start carving the base. Seat, as for the dial pointer, it is also placed on the side like a human accessory.

This production method is basically the same as the handicraft class for elementary school students. It is a slightly more difficult assembly with little technical content. Cheng Jinzhou couldn't help but said: "What should I do if the length and weight of both sides of this piece of wood are different?
Xiang Xin clicked his tongue, his right arm lit up with a faint light, and he saw a pattern appear on the straight wood. The surface seemed to be quickly reduced as if it were etched, and the speed of reduction was not the same on both sides.

"The symmetrical star array is specially used to measure the weight of items." Xiang Xin lifted his chin, looked at Cheng Jinzhou with contempt and said, "Most things can be balanced by the symmetrical star array. The method may take ten days."

Cheng Jinzhou was amazed at the magical star formation, and said, "It's really a lot of waste. Are those logs burned? It looks okay after being burned."

Xiang Xin was so angry that his bald head was shining, he ignored Cheng Jinzhou, and turned his hand to grab something that looked like a screw, and was about to twist it in the middle.

Cheng Jinzhou sneered and laughed again.

The upper body of the first-level star warlock trembled, he gritted his teeth and said, "What are you laughing at?"

"Your kind is what I call a tilted balance, which is the most common physical balance. This screw is a center of gravity screw, used to restore the moment balance. But even if it is restored, it should have problems Isn't it necessary?" Cheng Jinzhou pointed at Xiang Xin's semi-finished product, but every word was on point.

The anger on Xiang Xin's face couldn't help but calm down. In mathematics, the master is the teacher - there is no first in literature and no second in mathematics. If you are wrong, you are wrong, and there is no room for sophistry.

Cheng Jinzhou got up to speed at this time and started to give lectures on his behalf, saying: "What we are going to do is a pallet balance. Do you know what is the difference between it and an ordinary physical balance? Knife edge!"

While talking, he picked up a quill pen and gently drew two lines on the straight wood: "When the shape of the pallet balance itself is not a straight line, the problem we just mentioned will be solved naturally. And... ..."

Xiang Xin's head shook up and down slightly following Cheng Jinzhou's gestures, and when Cheng Jinzhou stopped, he said without thinking: "Go on!"

Cheng Jinzhou smiled, and turned to say: "There are many ways to make the three edges of the balance not in a straight line, but the essence is the same. To make the level of its own area balanced, well, it's very simple."

The tone at this moment is already the appearance of a teacher educating students.

Xiang Xin didn't notice the problem, and said seriously: "How do you make sure that the two ends are balanced?"

"Forget it." Cheng Jinzhou tapped his head with his finger and wrote down the relevant formulas casually: "It is better to use metal instead of wood. There is a problem of center of gravity. The rest is middle school content."

If physical experiments can still be faked, then the equations described in the most rigorous way are almost half-finished truths. The poor young astrologer was dizzy by a string of Greek letters, and his previous pride has long been lost to Guawa Island. Go, she memorized the formula and compared it carefully, and asked modestly: "This seems to be able to take into account the weight of the scale arm itself..."

"That must be considered. You can finish the rest." Cheng Jinzhou lay on the chair with his legs raised higher than his head, and he opened the door to look.

Xiang Xin was completely impressed by the formulas. Beautiful mathematical formulas were sometimes like beautiful scenery, making people intoxicated unconsciously.When doing chores like scales, she had no complaints or regrets. She even placed them left and right by herself, wanting to carefully compare the formulas.

Cheng Jinzhou looked up at the front of the ring, glanced at Xiang Xin's position from time to time, and after confirming that she really couldn't see customer service 010, he was completely immersed in his own world.

When it comes to reaching Star Alliance level 3, among the rights obtained, the ability to enter data and store one more book can only be counted as trivial details. What is really useful is the self-service trading platform.

In the void formed above the warning surface, a screen composed of more than a dozen pieces of information was in a trance, like an extended version of a computer screen, and the words on it made Cheng Jinzhou's heart itch.

"I want to buy Zodiac, the price is absolutely high, the buyer bears the travel expenses, and the bill is paid in cash..."

"Looking for a cheap manufacturing method for secondary synthetic heterocyclic compounds..."

"Sell third-class cotton fruit, which can increase the life span of the fruit..."

The second page cannot be flipped, Cheng Jinzhou stopped regretfully and said, "Can I take all these orders?"

"If you can meet the conditions, yes." Customer service 010 said casually.

"Then can I announce the news?" Cheng Jinzhou's eyes flashed.

Customer service 010 simply refused: "No."

"Why?" Cheng Jinzhou immediately expressed dissatisfaction.

The customer service is also used to his attitude, and said lightly: "The cost of posting a mission is 100 stars. If you want to place it on a higher page, the asking price will be even higher, plus shipping costs, etc., a 3-star star Members of the alliance can't spend enough money at all, and opening up is meaningless."

Cheng Jinzhou trembled slightly and said in a trembling voice: "Then if I can issue tasks, can I do any tasks?"

"The cost of an independent trading platform is expensive. Of course, you can issue tasks at will." Customer service 010's answer is very formulaic.

"Then I can post it too. Looking for Starfield Crossing, or take me home?" Cheng Jinzhou said with dry lips.

Customer service 010 was silent for a moment, and said: "It is theoretically possible, but not to mention the cost of crossing the star field, safety is very difficult to guarantee..."

"Since we can transport different goods in the star field..."

"The higher the intelligence level and cell activity, the higher the travel cost and the greater the risk." Customer Service 010 said, half-jokingly: "With your condition, it may go smoothly."
