Chapter 44
Two or three months after coming to the Great Xia Dynasty, Cheng Jinzhou was already desperate to go home.Although he dreamed back at midnight, he would recall the not-too-distant past, but never at a certain time, this feeling would be so strong, and his heart seemed to be stabbed by needles, beating unevenly and contracting.

The life of the Cheng family is actually very good. It is easy to have some fun in a wealthy mansion - games are meant to be played with others, but if there is a chance to return to the real hometown, Cheng Jinzhou will not Not the slightest hesitation.

I don't know how much time passed, but Xiang Xin hesitated and shouted loudly: "Cheng...Jinzhou, it's done, come and see."

It would be a long time in the future to raise the Star Alliance level again. Cheng Jinzhou gathered his mood and walked over with a straight face again, like a teacher reviewing his work.

Without the fierce look, Xiang Xin can barely be regarded as a bald little beauty. Reminiscent of his previous attitude, the kindness at this time is so touching that the tiger can skip a meal of breakfast.

Cheng Jinzhou's mood couldn't be described as low or high. He silently picked up the scale that Xiang Xin had made and looked at it for a while, then removed the beam.

Xiang Xin suddenly jumped up like a big-eyed wolf whose tail was stepped on. She did it for half an hour, but Cheng Jinzhou was destroyed.

Cheng Jinzhou glared at him and said, "The blade is not balanced."

The little bald head immediately stabilized.

A pallet balance is not difficult to make if you have the tools at hand.On a normal day, Cheng Jinzhou would probably just muddle along and make one, but today he was not in a good mood at all. He grabbed the scale and began to toss desperately on its basis.

From the calculation of the attenuation ratio, the structure of the balance has deviated from Xiang Xin's cognition.With the requirements of physical and chemical experiments at the level of the 17th century, they basically do not need balances below 0.1g. Without higher requirements, naturally there will not be many people studying it.

Science, to a certain extent, is still a matter of many people bullying few people-the existence of genius scientists is often the person who can improve the efficiency of everyone and reduce duplication of labor. However, they also need the dedication of countless people.

Xiang Xin stared intently at a balance, turning it back and forth in Cheng Jinzhou's hand.

The fake Dr. Cheng has very weak hands-on skills and is clumsy when moving up and down. However, the way he calculated and directly used mathematical parameters to determine the production plan opened the eyes of Mr. Star Warlock, from the moment balance equation to the calculation of the rotation ratio. Formulas are not familiar to astrologers. The most important thing is that the development of mathematics in this era is not enough to support all behaviors to be measured by mathematics. People inevitably have to use some experience and common sense, and these are often not Always correct.

In addition, there are many formula techniques, especially mathematical ideas, that people of this era cannot consider. To solve the same problem, people in the 17th century may have spent 20 years, but by the 21st century, these problems can already be solved. Left as homework.For a long time before computers existed, the research goal of mathematicians was simplification. They were even willing to express all problems with a simple formula, as if God was using a formula to control everything in the world.

Xiang Xin was staring at Cheng Jinzhou doing his homework with a scholar's eyes.

She didn't say a word even though the balance was ugly and nothing to add after it was reinstalled - the fields on the paper proved that this ugly balance is much more useful than the beautiful balance just now.

"You can give it a try." It took double the production time before Cheng Jinzhou put the scale back on the table.

He was much more silent than before, but Xiang Xin only thought that this was the result of concentration. He got the scale first, then quickly put the draft written with the quill on the table, and then carefully compared it with the numbers. .

As for the accuracy of the balance, she was not so concerned.

When the sun was fierce, Cheng Jinzhou moved outside the thatched shed, sat on the hot ground, curled up his hands and looked at the glittering scales in the small river not far away. No matter how different the natural scenery is, it always reminds people of many many……

"That's amazing, you should report it to the association." There was no trace of arrogance in the voice of the bald beauty, and it was entirely a tone of admiration.

Cheng Jinzhou nodded heavily, and suddenly felt indifferent and said, "You can do whatever you want."

Xiang Xin responded, then tidied up his gray-black robe with some embarrassment, and then whispered: "You are a genius, Mr. Cheng Jinzhou."

"Originally." Cheng Jinzhou finally laughed.

Different moods, harsh and arrogant laughter can also become a manifestation of arrogance. Xiang Xin's previous arrogance brought about by promotion is also like a lawnmower, without a trace.

Convinced by a little bald-headed beauty, Cheng Jinzhou also cheered up, and his tone returned to normal and asked jokingly: "At what level do you usually have a relatively powerful star array?"

Xiang Xin was stunned for a moment and explained: "The main thing is to be proficient in the application of star formations, and the most appropriate star formations should be used. However, in combat, the powerful star formations recognized by everyone can be learned from about the first-level star warlock .”

"Do you have a battle star array?" Not everyone will have a tattoo on the battle star array. If the ambition is not so ambitious, as a scholar or producer, the battle star array will have very narrow uses.

Xiang Xin hesitated for a moment, her left shoulder suddenly lit up, and after about two or three seconds, she stretched her left arm, and a bright ball of light rushed towards the slope in front of her.

During the explosion, a column of smoke more than ten meters high rose up, and the small stone that was hit collapsed, splashing down hundreds of meters away, and by the way, it stirred up spray in the small river.

The porters and villagers who were watching outside screamed and fled. The children ran home crying and screaming. Meng Dameng Er rushed up immediately.

Cheng Jinzhou waved his hand to indicate that it was okay, but carefully observed Xiang Xin's left arm with a research mentality.The latter was embarrassed to see it, so he covered it with his right hand and said: "The stirring light ball has a long range and a high hit rate, but its power is very average, and it has no other uses."

Xiang Xin's ball of light has at least the power of a 60mm mortar, something that Cheng Jinzhou had never experienced before in peacetime. He said with a slap in the face, "It's not that powerful."

"Mainly because of the high speed and accuracy." Xiang Xin said with a smile on his face: "Using the same star array, few people can hit a target 100 meters away. I can hit a large target 200 meters away."

With the power of her star array, it is really enough to hit a large target, and it is still a good artillery.

Cheng Jinzhou walked around her several times with interest, until Xiang Xin got a little annoyed before saying, "I don't know when I can choose my own star array."

"It depends on what type you want." Xiang Xin's attitude was surprisingly good, and he said seriously: "The combat star array usually makes certain requirements on the user's body, and in addition to computing power, you are not good at this aspect." There is no problem, but it is not easy to find a suitable star array, many complex star arrays, ordinary astromancers can't stab them, and the requirements are even higher if they are made to be used automatically."

No one is optimistic about Cheng Yang's physical fitness, and Xiang Xin is no exception.

Cheng Jinzhou didn't notice anything, squinted his eyes slightly, and whispered: "Is there a star array that can travel through space or time?"

Xiang Xin seemed to be taken aback, first pushed Meng Dameng Er away, and then said: "These are rare star arrays, and the requirements are very high."

"That's it?" Cheng Jinzhou's eyes lit up, the west didn't light up, and the east brightened. If the Star Alliance couldn't get what he wanted, it would be great if the Star Array could bring it.

For the sake of the balance, Xiang Xin reluctantly said: "These star arrays, just calculations will exhaust people, and if there is a slight mistake, the star warlock will die, and the production is also very difficult, almost only appearing in legends. , you don’t have to think about it.”

Cheng Jinzhou curled his lips. He would definitely think of it often. It was like a wild tiger arriving in the city. When eating steak, it would still miss the wild boar it caught.

The two were silent for a moment. Xiang Xin grabbed the scale and draft on the table and said, "I will submit the results to the association and I will use your name."

After the interruption just now, Cheng Jinzhou's homesickness suddenly subsided, and he shouted reluctantly: "Don't look for the association for the time being..."

Actionist Xiang Xin disappeared long ago on his horse.

After a long time, Shi Yan, who was frightened by the explosion, ran forward and said cautiously: "Third brother, why don't you go back and take a look?"

"Well, you ask someone to prepare a batch of things for the old man's school exam. The content should be concise and not too much. These are needed tonight." Cheng Jinzhou rubbed his chin and began to arrange: "In addition, ask someone to prepare some books for the provincial exam. The content can be broader, and some articles from previous years should be prepared.”

"Yes." Shi Yan agreed with a frowning face. Although these are sold in the market, it is not easy to find them all.
