Two or three months after coming to the Great Xia Dynasty, Cheng Jinzhou was already desperate for going home. Although he would recall the not-so-distant past in midnight dreams, there had never been a time when the sensation had been so intense, and his heart was beating and contracting unevenly as if it had been pricked by a needle.

The life of the Cheng family is actually very good, and in the mansion of a wealthy family, it is easy to find some fun - games and games are meant to be played with people after all, but if there is a chance to return to his real hometown, Cheng Jinzhou will not hesitate at all.

I don't know how long it took, Xiang Xin hesitated and shouted loudly: "Cheng ...... Jinju, it's done, come and see. ”

If you want to raise the level of the Star Alliance again, it is a very future thing, Cheng Jinzhou cleaned up his mood and walked over with a straight face, like a teacher who reviews work.

Removing the fierce color, Xiang Xin can barely be regarded as a bald little beauty, thinking of the previous attitude, the kindness at this time can simply move the tiger to eat one less breakfast.

Cheng Jinzhou's mood was not low or high, so he silently picked up the balance made by Xiang Xin and looked at it for a while, and then removed the beam.

Xiang Xin was suddenly like a big-eyed wolf who had been stepped on by the tail, and the whole person jumped up, she did it for half an hour, which allowed Cheng Jinzhou to be destroyed.

Cheng Jinzhou glared at him and said, "The knife edge is unbalanced." ”

The little bald head suddenly calmed down.

A pallet balance with tools at hand is not too difficult to make. On weekdays, Cheng Jinzhou probably has to make a living, but today he is not in a good mood at all, grabbing the balance, and tossing desperately on the basis of it.

From the beginning of calculating the decay ratio, the structure of the balance is detached from Xiang Xin's cognition. With the physical and chemical requirements of the 17th century, they basically do not need balances below O.1g, and there are no higher requirements, and naturally there will not be many people studying them.

Science, in a certain sense, is still a matter of more people bullying less - the existence of genius scientists is often the one who can improve the efficiency of many people and reduce the duplication of work, but they also need the dedication of countless people.

Xiang Xin looked at a balance intently, turning around in Cheng Jinzhou's hand.

The fake Dr. Cheng's hands-on ability is very weak, and it is inevitable that he will be clumsy up and down, but he can calculate and directly use mathematical parameters to determine the way of making the plan, but it has opened the eyes of His Excellency the Star Warlock, from the moment balance equation to the calculation formula of the rotation ratio, which is not familiar to the Star Warlocks, and the most important thing is that the mathematics exhibition of this era is not enough to support that all actions are measured by mathematics, and people inevitably need to use some experience and common sense, which are often not always correct.

In addition, there are many formulas, especially mathematical ideas, that are not something that people of this age can take into account, and solving the same problems that may have taken 2o years in the 17th century can be left as homework in the 21st century. For a long time without computers, the goal of mathematicians was to simplify, and they even had the will to express a problem in a simple formula, as if God was also using a formula to manipulate everything in the world.

Xiang Xin was staring at Cheng Jinzhou doing his homework with scholarly eyes.

Even if the scales were ugly and unattachable when they were reinstalled, she didn't say a word - the fields on paper proved that this ugly balance was much more useful than a beautiful one.

"You can give it a try." It took twice the time to make the zuò, and Cheng Jinzhou put the balance back on the table.

He was much more silent than before, but Xiang Xin only thought that this was the result of concentration, first took the balance in his hand, and hurriedly put the draft written with a quill pen in front of the table, and then carefully compared it with the numbers.

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

When the sun was fierce, Cheng Jinzhou moved outside the grass hut and sat on the hot ground, curled up with his hands and looked at the scales in the small river not far away......

"It's amazing, you should report it to the association." In the bald little beauty's voice, there was no longer a trace of arrogance, it was completely an admiring tone.

Cheng Jinzhou nodded heavily, and suddenly felt very indifferent and said, "Whatever you want." ”

Xiang Xin should be, and then sorted out the gray-black robe with some embarrassment, and then said in a low voice: "You are a genius, Mr. Cheng Jinzhou." ”

"It was." Cheng Jinzhou finally laughed.

Different moods, the harsh and arrogant laughter will also become the expression of the arrogant character, and Xiang Xin's previous arrogance due to the promotion is also like a weeder has been dealt with, and there is no trace.

Impressed by a little bald beauty, Cheng Jinzhou also shook his spirits, and asked in a normal tone: "A relatively powerful star array, how many levels do you usually have?" ”

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

"Do you have a battle array?" Not everyone will be stabbed into a Combat Array, and if the ambition is not so ambitious, as a scholar or producer, the purpose of the Combat Array is very narrow.

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

In the explosion, a pillar of smoke more than ten meters high rose, and the small stones that were hit collapsed and splashed hundreds of meters away, causing splashes in the small river by the way.

The villagers who were watching outside scattered and fled, and the children ran to their homes crying and screaming, and Meng Damenger rushed up as soon as possible.

Cheng Jinzhou waved his hand to signal that it was okay, but carefully observed Xiang Xin's left arm with a research mentality. The latter was embarrassed to look at it, and covered it with his right hand and said: "Stirring the ball of light, the range is long, and the hit is high, but the power is very average, and there is no other use." ”

Xiang Xin's ball of light has the power of at least 6omm mortars, which is something that Cheng Jinzhou has never had in peacetime, and he smacked his mouth and said: "This is still average." ”

"The main thing is that the degree and precision are high." Xiang Xin said with a smug face: "Using the same star array, there are very few people who can hit a target 1oo meters away, and I can hit a large target 2oo meters away." ”

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

Cheng Jinzhou circled around her several times with great interest, until Xiang Xin was a little annoyed before he said, "I don't know when I will be able to choose my own star array." ”

"It depends on what type you want." Xiang Xin's attitude was surprisingly good, and he said seriously: "Combat star arrays usually make certain requirements for the user's body, in addition to computing power, you don't have any problems in this regard, but it is not easy to encounter a suitable star array, many complex star arrays, ordinary star warlocks will not stab, to make it automatic use, the requirements are even higher." ”

No one would be optimistic about the body of the sick Yang Zicheng, and Xiang Xin was 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, and pushed Meng Dameng Er away before saying, "These are star arrays that are very difficult to encounter, and they are very demanding. ”

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

For the sake of the balance, Xiang Xin reluctantly said: "These star arrays, just counting will exhaust people, and if there is a slight difference, the star warlock will die, and the difficulty of making zuò is also very large, almost only in legends, you don't have to think about it." ”

Cheng Jinzhou pouted, he would definitely think of it often, it was like a wild tiger arriving in the city, and when it ate steak, it would still miss the wild boar it caught.

The two were silent for a moment, Xiang Xin grabbed the scales and drafts on the table and said, "I'll go and submit the results to the association, and I'll use your name." ”

After a break just now, Cheng Jinzhou's homesickness suddenly decreased, and he shouted with some reluctance: "Don't look for the association ...... for the time being."

Xiang Xin, who is an activist, has long disappeared without a trace when he rides a horse.

After a long time, after being frightened by the explosion, Shi Yan ran forward and said cautiously: "Third brother, go back and have a look?" ”

"Well, you have people prepare a batch of things for Daddy's school exam, the content should be fine, and these will be required tonight." Cheng Jinzhou touched his chin and began to arrange: "In addition, ask someone to prepare some books for the township examination, this content can be broader, and some articles from previous years and so on." ”

"Yes." Shi Yan's sad face agreed, although these are sold in the market, it is not easy to find them.
