The most famous artillery unit in later generations was the French artillery, Napoleon was born as an artilleryman and was proficient in mathematics, so he paid special attention to the quality of the French artillery team. Pen? Interesting? Pavilion wWw. ｂiquge。 info A qualified artilleryman in later generations needs to know at least some knowledge of differentiation at the surface. But now in this world, there are only two people with this ability, except for himself, that is Li Chunfeng's kid.

Mathematics is the foundation of all sciences, and the military is the practitioner of the latest technology, even if these people are made to memorize, they must be able to master the knowledge of differentiation. An artillery unit that does not understand mathematics, and the soldiers in it are not qualified artillery at all. But fortunately, the memory ability of these ancient scholars is not bad, and they don't need to be able to understand, they just need to be able to use it.

Although the firehorse is a weapon with a very different firing principle from a real artillery, the principle of calculating the trajectory and landing point is the same, and it can be regarded as a simplified version of the artillery. Li Er is a war maniac, he likes all guys who can put people to death, and the degree of liking is directly proportional to the lethality. After listening to Wang Mai's detailed introduction to the artillery unit, Li Er not only did not feel troublesome, but was more concerned about such an army comparable to the magic of the immortal family: "Li Chunfeng? When he returned to Chang'an, the king included him under his command. ”

"He is different from others, he has completely indulged in the kingdom of mathematics, you are the king of the world, he is the king of the mathematical world, it is not so simple to ask him to surrender honestly."

"Oh?" Li Eryi's eyes brightened when he heard this, "This king likes this kind of arrogant talent, no matter what, you can't miss it." ”

"The twisted melon is not sweet, if the king is really interested, I have a way to make him serve the Tang Army willingly." Wang Mai said in a foolish manner.

"Speak quickly!"

"He is now studying the laws of the movement of the stars, presumably the funds must be in short supply, those bull noses in the Daomen have no good intentions, they will not support him, the king can help him in the name of funding scientific research, take other people's hands short, presumably this kid will not refuse your request."

"I see," Li Er nodded, "It's just some wealth, he can say anything he wants, and if he can get such a talent, this king will naturally spare no effort." ”

easily found a rich man for Li Chunfeng, and when he arrived in Chang'an, he must let this kid invite him to dinner, and I don't know how he studied. With the knowledge of calculus, it should not be difficult for him, the problem is how to make the world accept that it is not the center of the universe, not even the solar system, and that the earth is just an insignificant speck of dust in the universe.

People are like this, it is difficult to accept their own insignificance. It's like an actor who happily took a script, thinking that he was the protagonist, but suddenly found that he had become a passerby, and he must have been incomprehensible in his heart, not a day's work.

Li Chunfeng, this kid is simply a demon, not something that ordinary people can compare, and he threw his two disciples away from a galaxy. Liang San is still young, his temperament is relatively honest, and he lacks the spirit of initiative and enterprising, which is not the material for research. Wang February's is more lively, but his mathematical talent is also very average, and he is half a pound and eight taels, but it is more than enough to teach these scholars who don't know what a function is.

Wang Yuanwai excitedly watched his son being called over by Li Er for questioning, rubbing his hands and walking back and forth in place. This Qin Wang Bacheng is in love with his son, I didn't expect that the decision to send him to the national prison would have such a big harvest, this Mr. Wang is really a nobleman, his son can worship under his door is really the ancestral tomb There is green smoke on it, and I have to pay homage to my ancestors as soon as possible, and bless my son with a smooth career.

After chatting for a few sentences, Wang Eryue came back with his head drooping, looking listless.

Wang Yuanwai's heart sank when he saw his son's expression, and he took Wang Eryue's hand and asked in a low voice: "What's the matter, King Qin doesn't look down on you?" ”

Wang February: "I gave it to a nine-grade petty official." After speaking, he could no longer suppress the joy in his heart, and his face was full of smiles.

It took a long time for Wang Yuanwai to react, this stinky boy was making fun of Lao Tzu, and immediately took off his shoes: "Come here, Lao Tzu will beat you to death!" ”

"Don't don't, don't ......" Wang Er hurriedly said to him, "Dad, I'm just joking with you, His Royal Highness King Qin wants to see you." ”

"You still want to take it to Kaishabu, how big an official is King Qin, can you still see me? You come over to me, for the sake of you being an official, Lao Tzu will beat you twice less this time. ”

"It's true, you hurry up, Your Highness is looking this way?" Wang February, holding his head, began to play hide and seek with his Lao Tzu.

"Huh?" Wang Yuanwai glanced at Li Er in disbelief, Li Er was looking at the father and son with a smile, turned his head and hurriedly put on his shoes, "You stinky boy, you can kill Lao Tzu." ”

The two fathers and sons came to Li Er with red faces, and Li Er asked with a smile: "It seems that Wang Er's foreign teacher is very strict, no wonder Wang Eryue is very young, and his knowledge is extraordinary." ”

"The king laughed, I am a businessman, and there is no way to teach my son, it is all Mr. Wang's credit." Wang Yuanwai lowered his head, never daring to look at Li Er, who was close at hand.

"Wang Yuanwai doesn't have to be humble, if it weren't for you benevolent grain merchants, Luoyang doesn't know how many people would starve to death." Wang Mai said on the side.

Li Er nodded: "The king has also heard about the good deeds of the king, it is indeed a good family, and it also indirectly supported our army's attack on Luoyang, the Tang Dynasty has never treated meritorious people lightly, Wang February's knowledge is very appreciated by the king, I don't know if you are interested in letting him serve under the king's account?" "When the rebels were able to take the granary of Guocheng, the support of these local grain merchants was indispensable, although their motives were not so simple, but after all, they also indirectly supported the revolution.

"It is a blessing for a child to be able to serve His Royal Highness the King of Qin......" Wang Yuanwai's excited words were incomplete.

Wang Mai pouted, this Li Er is too capable of fooling, people have made contributions, you will reward others for this, and you will take advantage of the cheapness? Thinking of this, his eyes rolled: "Since the king thinks that the king has merit outside the king, why don't you give a pair of ink treasures?" ”

"This ......" Li Er hesitated for a moment and nodded, "Okay, then the king will be ugly, I hope the king will not dislike it." "The importance of Luoyang's eastern capital is self-evident, and this king is a local businessman, and the benefits of supporting him are still obvious.

Wang Yuanwai's hands trembled and took the four big words "Good House" from Li Er's second-hand, knelt on the ground and kowtowed heavily to Li Er.

"Outside the king, this word must be kept in good hands." Wang Mai reminded. Li Er became the emperor later, and this character will appreciate in value.
