Future library

Two or three months after arriving in Daxia Dynasty, Cheng Jinzhou was already desperate to return home. Even though he would recall the not-too-distant past when he dreamed about it at midnight, there had never been a time when this feeling was so strong, and his heart felt like it was being pricked by needles, beating and contracting unevenly.

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 her fierce look, Xiang Xin could barely be regarded as a bald beauty. Reminiscent of her previous attitude, her kindness at this time was so touching that it made the tiger skip a 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 not destroyed.

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

The little bald man immediately felt at ease.

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.

Starting from the calculation of the attenuation ratio, the structure of the scale was beyond Xiang Xin's understanding. Based on the physical and chemical experimental requirements of the 17th century, they basically did not need a balance below 0.1g. Without higher requirements, naturally there would not be many people studying it.

Science, to a certain extent, is still a matter of more people bullying fewer people - the existence of genius scientists is often the one who can improve everyone's efficiency and reduce duplication of work. However, they also require the dedication of countless people.

Xiang Xin stared at a scale and turned it around 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 even had the desire 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.

Even after the scale was reinstalled, it was so ugly that there was nothing to add to it, but she didn't say a word - the fields on the paper proved that this ugly scale was much more useful than the beautiful scale 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 scale, she was not that concerned.

When the sun was shining brightly, Cheng Jinzhou moved outside the hut and sat on the hot ground. He curled up his hands and looked at the shining scales in the river not far away. No matter how different the natural scenery is, it can always remind people of many things. 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 completely a tone of admiration.

Cheng Jinzhou nodded solemnly, and suddenly felt very indifferent and said, "It's up to you."

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

"It is." Cheng Jinzhou finally laughed.

In different moods, harsh and arrogant laughter will also become a manifestation of arrogance. Xiang Xin's previous arrogance due to promotion has disappeared as if it had been treated with a lawnmower.

After being impressed by the little bald beauty, Cheng Jinzhou also cheered up, and his tone returned to normal and he asked jokingly: "At what level do you usually have a more powerful star formation?"

Xiang Xin was stunned for a moment and explained: "The main thing is to be proficient in the use 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?" Not everyone will tattoo the battle star. If the ambition is not so ambitious, as a scholar or producer, the use of the battle star is very narrow.

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

In the loud explosion, a column of smoke that was more than ten meters high rose up. The small stone that was hit fell apart and splashed hundreds of meters away, stirring up splashes of water in the 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 attitude. 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 was at least as powerful as a 60mm mortar, something Cheng Jinzhou had never experienced during peacetime. He smacked his lips and said, "This is not so 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 large targets. In total, it is still a good artillery piece.

Cheng Jinzhou walked around her several times with great interest, until Xiang Xin became a little annoyed and said, "I don't know when I can choose my own star formation."

"It depends on what type you want." Xiang Xin's attitude was surprisingly good, and he said seriously: "Combat star formations usually make certain requirements for the user's body, as well as computing power. In this regard, you There’s no problem, but it’s not easy to find a suitable star formation. Ordinary star warlocks can’t stab many complex star formations, so if you want to use them automatically, the requirements are even higher.”

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

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

Xiang Xin seemed to be startled, and pushed Meng Da Meng Er away first, and then said: "These are star formations that are difficult to encounter, and the requirements are very high."

"So you have it?" Cheng Jinzhou's eyes suddenly lit up. If the west is not bright, the east is bright. If you can't get what you want from the Star Alliance, it would be great if the Star Array can bring it.

For the sake of the scale, Xiang Xin reluctantly said: "These star arrays are exhausting just to calculate. If there is a slight mistake, the star warlock will die. Moreover, it is very difficult to make. They almost only appear 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 Dad to take the school exam. The content should be precise but not too much. We will need these tonight." Cheng Jinzhou touched his chin and began to arrange: "In addition, ask someone to prepare some books for the provincial examination. This The content can be broader, and some articles from previous years should be prepared, etc.”

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