The first-class star sorcerer Xiang Xin's forehead shone in the sun. She squinted her eyes slightly and still looked down at Cheng Jinzhou. There were more than a dozen pieces of scattered materials on the square table in front of her, all of which were regular standard pieces.

After the hard work over the past few days has been rewarded, Cheng Jinzhou has become more and more confident. He walked to the square table with his hands behind his back and said with a polite voice: "Do you still remember how to make ordinary balances?"

"Of course I can do it." Xiang Xin also turned around at the end of her sentence. She has learned astrology for more than ten years, and making items is one of them.

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

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

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

"Can you make a balance with an accuracy of 0.1 grams?" Cheng Jinzhou said with a faint expression: "You don't want to make ordinary balances, but you can't make high-precisions. At this time, if you want to steal, you have to make a balance first."

Xiang Xin's eyes were filled with anger, and she snorted heavily. She unexpectedly did not resist and grabbed the materials on the table and started to do it. Cheng Jinzhou's theory was serious before, and she really wanted to take a look. Astrology, even if it had long eyesight, could gain a lot. She would not give up such an opportunity. At this point, Cheng Jinzhou looked very accurately.

However, from Xiang Xin's convex expression that seemed to be a rabbit hit by an electric shock, it can be seen that if Cheng Jinzhou failed to produce, the outcome would be very miserable.

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

Xiang Xin first took out a long straight wood, engraved a mark on the center position, then placed it in his hand, swayed left and right until both sides were balanced, then remembered the center of gravity with a knife, and then began to engrave the base. As for the dial pointer, it was also placed on one side like a human accessories.

This method of making is basically the same as that of primary school students' manual classes. It is a slightly more difficult assembly. The technical content is pitiful. Cheng Jinzhou couldn't help but say, "What should I do if your wood has different lengths and weights on both sides?

Xiang Xin tskated, and a slight light appeared on his right arm, and a pattern appeared on the straight wood. The surface of it seemed to be etched, and the speed of decreasing on both sides was different.

"The symmetric star array is specially used to measure the weight of items." Xiang Xin raised his chin and looked at Cheng Jinzhou with contempt and said: "Most things can be balanced through the symmetric star array. If it is an ordinary person who carves with a knife, it may take ten days."

Cheng Jinzhou was amazed by the magical star array and said, "There is a lot of waste. Did the wood be burned? It looks good if it burns out."

Xiang Xin was so angry that she was about to shine on her bald head. She ignored Cheng Jinzhou and grabbed something like a screw, and then twisted it in the middle.

Cheng Jinzhou sneered and laughed again.

The first-level star warlock's upper body shook and gritted his teeth and said, "Why are you laughing at?"

"You are what I said, the scale that will rise up, which is the most common physical balance. This screw is a center of gravity screw, used to restore moment balance. But even if it is restored, don't it still have problems?" Cheng Jinzhou pointed at Xiang Xin's semi-finished product, but every sentence could be said to the point.

Xiang Xin couldn't help but stop the anger on his face. The master of mathematics is the master of the master - there is no first in literature and no second in numbers. If you are wrong, you are wrong, and you don't even have room for quibbling.

Cheng Jinzhou started to grasp it at this time, and took the initiative to teach as a teacher, saying, "What we want to do is a tray balance. Do you know what the difference is between it and an ordinary physical balance? Knife!"

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

Xiang Xin's head swayed gently as Cheng Jinzhou's gesture. Seeing that Cheng Jinzhou stopped, his mind didn't react and said, "Continue!"

Cheng Jinzhou smiled and said instead: "There are many ways to make the three blades of the balance not on the straight line, but the essence is the same. It is very simple to make the area horizontally balance, and it is very simple."

The tone at this moment is like the teacher educating students.

Xiang Xin hadn't noticed the problem yet and said seriously: "How do you determine the balance between the two ends?"

"Count it." Cheng Jinzhou pointed his finger at his head and wrote down the relevant formula casually: "It is better to use metal, not wood, as there is a problem with the center of gravity, and the rest is middle school content."

If physics experiments can still be false, then the equations described in the most rigorous way are almost the truth of a semi-finished product. The poor young astrology warlock was dizzy by a string of Greek letters. The pride of the past had long been thrown to Guawa Island. While remembering the formula carefully, she asked modestly: "This seems to be able to take into account the weight of the balance arm itself..."

"That's something that must be considered. You can finish the rest." Cheng Jinzhou lay on the chair, his legs raised higher than his head, and he had already opened the ring and looked at it.

Xiang Xin was completely impressed by the formula. The beautiful mathematical formulas are sometimes like beautiful scenery, which makes people unconsciously intoxicated. When she does a chore like a balance, she has no regrets, and even puts it on her left and right, wanting to carefully compare the formulas.

Cheng Jinzhou looked up at the ring face, glanced at Xiang Xin from time to time, and confirmed that she could not see the customer service post-010s, and was completely immersed in his own world.

When it comes to the Covenant level 3, the ability to enter information and store one more book can only be regarded as a detail, a truly useful one, or a self-service trading platform.

In the void formed above the ring surface, the screen composed of more than a dozen pieces of information was vague, like an extended computer screen, and the text on it made Cheng Jinzhou feel itchy.

"If you want to buy tiny stone, it is absolutely high. The buyer will bear the travel expenses and pay the bills in cash..."

"Purchase cheap manufacturing method for secondary silk-combined heterocyclic compounds..."

"Selling third-class cotton vegetarian fruit can increase the lifespan of fruits..."

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

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

"Then can I post a message?" Cheng Jinzhou's eyes shone.

Customer Service 010 rejected it very simply: "No."

"Why?" Cheng Jinzhou immediately expressed his dissatisfaction.

The customer service was used to his attitude and said lightly: "The cost of posting a task is 100 star yuan. If you want to place it in the previous page, the asking price will be higher. In addition to transportation costs, etc., the members of the 3-level star alliance cannot pay enough funds at all, so it is meaningless to open it."

Cheng Jinzhou shook slightly and said tremblingly: "If I could publish a mission, would any mission be possible?"

"The cost of independent trading platforms is expensive, of course, you can publish tasks at will." Customer Service 010's answer is very formulaic.

"Then I can also post it. Looking to travel through the star domain, or send me home?" Cheng Jinzhou said with dry lips.

Customer service 010 was silent for a moment and said: "It is feasible in theory, but it is very difficult to guarantee safety if you don't mention the cost of traveling through the star field..."

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

"The higher the intelligence level and cell activity, the higher the time travel cost and the greater the risk." Customer service 010 said, half jokingly: "In your state, it may be very smooth."

It is indeed the first place in the newcomer list. The comrades are very strong, thank you very much.
