Fu Xuechen had a bottom in his heart, and couldn't help but smile at Yu Zuo: "But have you ever thought about it, Your Highness, just like the blade of the sword blade from the original just easily damaged copper, all the way to today's fine iron system, the power has doubled, and the same is true for firearms?" From the day it appeared, it was destined that it would also develop all the time, becoming more and more powerful, getting closer and closer to the destructive power of fire, until it finally replaced the sword and bow? ”

Yu Zuo didn't believe it in his heart, but he couldn't help but be in a trance by Fu Xuechen's determined and confident demeanor: "What did you say? Instead of swords, bows and arrows? How is this possible? ”

"How could it not be?" Fu Xuechen turned on the flickering mode: "Let's take the nomadic cavalry in the north as an example!" They have grown up on horseback since childhood, with the power of this horse to dominate the world, although our bow and arrow can be attacked from afar, a single arrow is not powerful enough, the number of sparse marksmen in the army is not to say, the number is small, it is difficult for ordinary sergeants' arrows to hurt people, let alone hurt horses, and when the other party arrives on horseback, the sergeant can only be slaughtered, how can two legs not outrun four legs, right? ”

"Swords and spears are melee weapons, and you have to get close to the enemy to start fighting, right? At this time, we have to have our own sergeants also ride horses, otherwise we can't fight the opponent's cavalry, but if both the enemy and us are fighting on horseback, how many of our troops can match their nomadic riding skills? ”

Yu Zuo frowned, his heart was heavy when he heard it, he knew that although his father said that he unified the Central Plains and used the Great Wall to guard the threat from the north from the Great Wall, but in fact, his father also caught up with the good time when several ethnic groups in the north were in conflict with each other and scattered sand.

One day, if there is a male lord in the north, knead this plate of loose sand, and then wave the army south to Koubian, the disaster will be too serious, the infantry is invincible to the cavalry, and the cavalry is difficult to attack, Fu Xuechen's words are really poked at the weakness of the military of the Darong Empire.

"So! By the time the firebolt is fully developed, all this will not be a problem! Fu Xuechen was still talking: "When the time comes, everyone will have a firearm, hit people on the top, hit horses on the bottom, ten times a second, a few bullets can kill you, can you completely replace the sword, bow and arrow!" ”

Yu Zuo squinted unconsciously: "Are you talking about fire?" It's not an unknown 'artifact' that you imagined, right? ”

Hearing a hint of ridicule in the tone of the six princes, Fu Xuechen stopped doing it: "How can I be imaginary? You said that the current firecracker is slow to reload, so you can find a way to make an ammo pack with the same size in advance, and when you want to use it, you can just plug it, and the reloading speed will be faster, isn't it? Or change the front loading of the projectile to the rear loading, which can also speed up the reloading speed a lot! ”

"There's also the problem of the lead, it's slow and troublesome to light the lead, and it can't be used in rain and snow, so isn't there such a thing as flint? Cut the flint into the size of a bean, set up a small mechanism in the firebolt, and pull the trigger to directly ignite the gunpowder bag in the chamber, isn't it? ”

"There is also the problem of projectiles, I feel that the penetration of the round ball-shaped bullet is insufficient, so let's make the warhead pointed! If you study the composition of gunpowder more and find out the same amount of gunpowder, but the more powerful gunpowder, won't the penetrating power of the bullet come up? ”

"As for accuracy, rifling and crosshair! There is also the problem of exploding the chamber, which must be due to the poor quality of the barrel! Let those craftsmen work hard to make a blast furnace that can burn higher heat and smelt better quality molten steel! And the quality of the steel has improved, the diameter of the barrel can be reduced, and the weight can be lightened and easy to carry......"

Speaking of this, Fu Xuechen suddenly realized that he seemed to be talking too much!

Fortunately, at this time, the time for the riding and archery class seems to have arrived, and the other princes and companions have arrived at the martial arts arena one after another, and Master Na and Master Liu, who appeared in the last martial arts test, also appeared on the edge of the martial arts arena.

Fu Xuechen took the opportunity to stop talking: "In short, there are still many things that can be improved in the fire gun, I believe that these improvements have all been made to the extreme, and the era of the fire gun replacing the sword and bow and arrow will come!" Alright, the two teachers are here, Your Highness, it's time for us to get ready for class! ”

Fu Xuechen was secretly happy, and finally succeeded in dragging the time through a flicker, avoiding the pain of losing arm strength.

Yu Zuo was really stupid by her horn, this sentence sounded like it was bragging, but if you think about it carefully, it seems to have a strong feasibility, and it seems that it is really improved according to her, one day, the fire gun can really develop strong to the extent that it will eventually replace the sword, gun and sword, not to mention anything else, just using flint instead of the lead, it can be called a wonderful improvement......

Thinking about these things from time to time in his mind, Yu Zuo actually had an unprecedented experience, and the whole afternoon's riding and archery class was almost in a state of trance, all relying on his usually excellent riding and archery foundation, before he was confused.

Compared with later generations, the time of the cavalry and archery martial arts class arranged in the afternoon in this era is not long, from half an hour to half an hour, and it will end in an hour, according to the time of later generations, that is, between two and four o'clock in the afternoon, and the school is quite early.

Taking advantage of the time after school, the younger princes will generally play more in the martial arts arena, and the older princes, such as the fourth prince, will go to the royal library to read a lot of books, and can also take the opportunity to ask the bachelors of the library for teaching.

Today's Yu Zuo was in a trance, he didn't have the heart to play, and he didn't return to the prince's office, but unconsciously slipped outside the Qianming Palace.

Emperor Yuan An was in the Qinzheng Hall in the Qianming Palace at the moment to review the folds, and heard Zheng Ze say that the six princes were outside the palace gate, and he didn't report that he wanted to see him, so he was wandering there, muttering a few words from time to time, looking full of thoughts, he couldn't help but be surprised, and immediately signaled Zheng Ze: "Pass him in!" ”

Even if it is a father and son, but after all, the day before yesterday, there was no opportunity to cultivate the relationship between father and son, and finally the battle was over, and his father became a majestic emperor again, Yu Zuo's feeling for this father can be said to be both alienated and awe, obviously there are many questions in his heart that cannot be solved, and only his father seems to be able to answer him in the palace, but when he came unconsciously, he hesitated, and suddenly heard the summons, and he almost turned around and ran away in fright.

"The son knocks to see his father!" According to the etiquette in the palace, Yu Zuo supported his left knee, knelt on his right knee, and bowed to the ground with his right fist.

"Let's go!"

Hearing Emperor Yuan An's call, Yu Zuo stood up and stood aside with his hands bowed.
