"Bronze weapons are heavy and not sharp enough, and they are not flexible enough to break easily, and when I was in the mountains, I once learned the method of forging steel with an old man, and the knives that were made were light and sharp, and the tenacity was good, and they could easily kill the beasts in the mountains, and the arrows made of steel could easily shoot through the heads of tigers. This is a hunting knife and a repeater that I have built myself, and this crossbow has a range of more than 100 meters and is much more accurate than a normal bow. After speaking, Liu Yu took out a hunting knife and a two-foot-long iron-backed crossbow. Handed it to Guan Xing.

Taking the knife and crossbow arrows, Guan Xing looked at it carefully for a long time. shouted: "Come on, get weapons." After a while, a family member brought a few bronze swords. "Use the bronze sword and this knife to slash each other a few times. Guan Xing commanded. Immediately, the two family members each took Liu Yu's hunting knife and a bronze sword and stood still, and "Dangdangdang" slashed a few swords at each other, only to see that the hunting knife was still intact, and the bronze sword was already scarred and could not be used anymore.

Looking at the scene in front of him, Guan Xing suddenly became interested, and said to Liu Yu: "The knife you built is really good, what is the power of the crossbow arrows you make?" Liu Yu replied: "My light crossbow can be fired continuously, at most ten arrows at a time, and nothing can be missed within 500 meters, if its size is enlarged again, it can shoot thousands of kilometers away." Do you want to give it a try?" "Okay, if it's really like what you said, I will definitely ask the emperor to give you credit." Big brother, you really brought a baby, if the old ghost of Liangshan didn't go crazy if he knew the news, let's go, go, let's go to the martial arts arena to see how the demeanor of this magical iron-backed crossbow is? With such a weapon, we can have more hope to resist the beasts and demons. ”

Seeing Guan Xing's elated appearance, Zhang Wenyu also bowed his head and said: "It's okay, it's also a blessing of the empire to have such a good thing, let's go and see it together, I really didn't expect Xiao Yu to have this hand." ”

Under the leadership of Guan Xing and Zhang Wenyu, the group rushed to the martial arts arena, which was very wide enough for a thousand soldiers to practice, with a length and width of about 800 meters. Guan Xing ordered people to prepare the arrow target, Liu Yu stood still about 500 meters away from the arrow stack, took out the crossbow arrow and aimed at the arrow target, and pressed the machine, ten arrows shot out in an instant, swishing a few times just fell, already hit the bull's-eye, and a few arrows penetrated the target, and flew out more than ten meters before landing.

Watching Liu Yu's relaxed performance, everyone was dumbfounded, the range of this crossbow is much farther, not to mention, this penetrating power is also amazing, it doesn't take Liu Yu to spend any effort to shoot through the arrow target, it is so much stronger than the bow they usually use, and the accuracy is also so strong. Guan Xing thought to himself, even the strong bow he used in his heyday could not shoot so far, how much power would this be? This crossbow is really amazing, it can shoot ten arrows at a time, what kind of situation will it be if it is equipped on a large scale! The combat effectiveness will definitely be greatly improved.

Thinking of this, Guan Xing said to Liu Yu: "Are the children interested in getting an errand under my account?" Liu Yu thought for a while and said: "Thank you for the kindness of Old Man Guan, the kid is still young in knowledge, and he should learn more, so that he can better serve the empire in the future, if he can learn something in the future, he must not forget the cultivation of Old Man Guan." I have already sorted out the method of making this hunting knife and crossbow arrow, so I will give it to Old Man Guan, which can be regarded as a contribution to the empire. As he spoke, he handed the two small books to Guan Xing.

After listening to Liu Yu's words, Guan Xing couldn't help but appreciate Liu Yu a little more, and said: "I heard that you also want to apply for the Bokan Military Academy, so let's do it, I will write a letter of recommendation, which can allow you to study directly without the exam, what do you think?"

"No, I still have to take the exam by myself, I have confidence in myself, and I can train myself. Only by constantly undergoing trials can we grow. Liu Yu shook his head and declined Guan Xing's kindness. "Okay, he deserves to be a child that the eldest brother is optimistic about, and he has ambition. It's just as you think, but I won't be greedy for your merits, and when these weapons are approved by Your Majesty, I will definitely ask Your Majesty to reward you. Big brother, I'm so happy today, I want to have a few more drinks with you, don't shirk, you must have fun. Let's go, it's almost time, it's time to take a seat. As he spoke, he grabbed Zhang Wenyu with one hand, and pulled Liu Yu with the other hand to walk first.

After this exchange, Guan Xing also became enthusiastic about Liu Yu, and even Zhang Wenyu had a little more respect than usual, after all, these are all beneficial to the empire, and it is more hopeful to have more such talents in the empire.

In the midst of the staggering, everyone was very happy, raising glasses to each other or whispering to each other. During the banquet, Guan Xing toasted Zhang Wenyu frequently, after all, the two had not seen each other for many years, and they had a lot to say to each other. Just when everyone was having their best eating, an unkempt man rushed in and ran straight to Guan Xing, shouting as he ran: "Third brother, third brother, I heard that someone has created an iron-backed crossbow, which is very powerful, but is there really such a thing? What does this crossbow look like, how powerful is it? Let me see." As soon as he finished speaking, he was stunned when he saw Zhang Wenyu sitting next to Guan Xing, and then pounced on Zhang Wenyu and cried: "Big brother, why are you so willing to be separated from our brothers, I can't see you for so long, and I don't know where you have gone, I want to die of the seventh child, woo woo woo ・・・・・・" Looking at this person who was crying so sadly, Guan Xing said angrily: "Liangshan, the boss is not small, and he cries like this in front of his juniors, and he is not afraid of people's jokes." ”

"Who dares to laugh, I'm excited to see my eldest brother, how can you have no favor at all, you don't give me such a good thing, let me borrow wine all day to drown my sorrows, these words have made me bitter. Hurry up and show me the crossbow. Liang Shan said with a sob. After speaking, he hugged Zhang Wenyu and cried, "The third brother always bullies me, now it's okay, the eldest brother is here." Big brother, you have to call the shots for me. ”

Looking at Liang Shan, who was holding himself and crying, Zhang Wenyu's eyes couldn't help but moisten, and he patted Liang Shan's back: "Seventh brother, okay, don't cry." Isn't the eldest brother here, I've worked hard for you all these years. "Why did I bully you? I will have someone send you that iron-backed crossbow tomorrow, you can keep these two booklets, it is the manufacturing method of this crossbow, and the manufacturing process of the knife, you study it slowly, the eldest brother is here today, it is a happy thing, you don't cry and cry, come and drink more of our three brothers." ”

As soon as he heard that there was wine to drink, Liang Shan took the pamphlet handed to him by Guan Xing and put it in his arms: "Today, the eldest brother came and got the method of making the iron-backed crossbow, what a great joy! Come on, come on, eldest brother, third brother, drink and drink, if you don't get drunk, you won't return, I'll do it first." Before he could finish speaking, a large glass of wine was already in his stomach.
