"It's beautiful!" A blacksmith muttered intently as he stared at the sword.

"Dang!" Zou Yu casually grabbed a knife flower and slashed off an iron ingot next to him, only to hear a crisp sound, the palm wide, and the three-finger-thick iron ingot was neatly disconnected.

Retracting the knife and looking at the blade that left no trace, Zou Yu grinned with a satisfied smile.

There are test stones and wooden stakes in the forging place, Zou Yu walked over, controlled the strength, and swung out more than ten knives in succession, not letting him down, whether it was a stone or a wooden stake, all of them were cut in two, without a little resistance, as if cutting tofu.

"Hahaha! Good knives! What a knife! Zou Yu couldn't help laughing, he was very satisfied and proud that this kind of treasure knife was actually forged by himself.

"Congratulations to the general for forging a treasure sword!" Everyone congratulated.

"You guys are not bad, this kind of knife cannot be mass-produced, and it is not worth promoting." Zou Yu explained that he was worried that these blacksmiths would be happy to hunt and follow suit, but they would delay the production of ordinary weapons.

"General, the steel crossbow has been prepared, please take a look!" Seeing Zou Yu coming down, a blacksmith stepped forward to report.

Another advantage of getting Liaodong City is that many craftsmen have been captured, and finally someone knows how to make repeaters.

However, this time, Zou Yu planned to use steel to make the arm of the crossbow, and it was made by using a recurve bow. The recurve bow is well understood, that is, the back of the bow is inward, and the recurve bow is said to be more economical and has a longer range.

Zou Yu looked at it, and there were two kinds of crossbows made, one was a siege crossbow and the other was a stepping crossbow.

Siege crossbow, in order to pursue strength, will use several bows as arms, generally three, so it is also called three bows strong crossbow, but this is a crossbow arm made of steel, naturally not so troublesome with three, crossbow arrows are made of hard wood, the front end is a steel arrow made of molds, and the tail of the arrow is made of iron sheets.

Except for the crossbow arm is recurved, there is only one crossbow arm, and the others have not changed, so this is not difficult for craftsmen, and at present, it is only waiting for the experimental power.

Siege crossbow, generally need thirty people to cooperate with the operation, the same is true of the steel arm siege crossbow, at the beginning or went to thirty people to operate, mainly winding, need to twist twelve people at the same time, but need more people, of course, the power should not be underestimated, the siege crossbow is installed at a time a large six small seven arrows, the power can open the mountain and crack the stone, nail into the city wall, the siege soldiers can climb up from this.

On one side, there was already a target, and soon, twenty-four strong men stepped forward, some of them held the siege crossbow, some of them began to twist the crossbow strings, and then the people on one side began to place the arrows.

"General Qiyu! The bolts are ready! One of the fighters reported loudly.

"Put!" Zou Yu ordered in a deep voice.

"Buzz!" The sound of a bowstring sounded, and at the same time, there was a "Bang Bang Bang!" The sound reached everyone's ears at the same time.

Everyone looked intently, and five hundred meters ahead, there were seven arrow shafts stuck in the earthen wall, which were trembling!

"Not bad!" Zou Yu exclaimed, he didn't need to go over, just look at the depth of the arrow, and he knew what the effect was.

"How do you feel, compared to the old crossbow arrows?" Zou Yu turned his head and asked.

"General Hui, my subordinates feel a lot lighter, and it seems that they can be wound without so many people." The soldiers thought for a moment, and one of them said.

"Uh-huh!"

"It's a lot lighter!" The others nodded their heads in unison.

"Take a hundred meters back, try again, and see how many people are winding properly." Zou Yu nodded.

Soon the siege crossbow was moved to a distance of 600 meters, rewound, and test-fired. The result is very gratifying, only twelve people are needed, it can be easily wound, and this one, it saves twelve fighters, and at six hundred meters, the power is still not reduced, obviously this is not the limit. As for the final limit distance, only slowly experiment, but this is already much stronger than the current siege crossbow, according to a warrior who has used a siege crossbow, the current Goguryeo siege crossbow, the range is more than 500 meters, and the Central Plains siege crossbow, is about 700 meters.

In other words, at present, the siege crossbow is already considered top-level, not to mention the use of more than a dozen people to operate it. In this regard, it was only enlarged and lengthened crossbow arrows before, which is simply incomprehensible, and this is the benefit of talent.

The next step is the crossbow, which is a crossbow that uses the power of the arms, feet, and waist to stretch the bow in a sitting position at the same time. When using, sit flat on the ground and lay the crossbow flat in front of you. The left and right soles of the feet are inserted into the thumbs, followed by the crossbow split, pry the waist hook, and hook the crossbow string. Pull the waist hook with both hands and push the soles of your feet forward. The splitting body fell backwards, and with force, the machine started from the beginning, and the vanadium structure was hung.

Zou Yu's crossbow also uses a recurved crossbow arm, and as soon as the soldier gets started, he smiles and reports loudly: "General Qiyu, it's much lighter!" ”

"Shoot!" Zou Yu nodded and ordered.

The results of the crossbow experiment are also very good, and two hundred meters away, it still has lethality.

The general bow and arrow, the effective range of the straight line is 50 to 70 meters, this is a soft bow, the soft bow is also the most common bow and arrow, made of wood and silk thread, or animal tendons, and only the soft bow can make most warriors shoot continuously.

Next is the longbow, the longbow is also called the hard bow, represented by the horn bow, the effective range of the straight line is about 80 to 120 meters, this kind of bow is 1.5 to 2.5 meters long, and it takes a good physique to shoot continuously, otherwise the fire will be extinguished after two or three shots, how to defend the city.

Archers have very high requirements for arm strength, and they are not as easy as imagined, especially continuous shooting, which is why there are only one or twenty arrows in a barrel, one is not easy to make, and the other is that there are more, and there is no physical strength to pull the bowstring.

Of course, this is a normal situation, and for a marksman, it is a different situation.

In addition to these two kinds of bows, that is, crossbows, general crossbow arrows, the range is about 100 meters, and the power is not bad, but the crossbow arrows are generally fired horizontally, so that the power can be maximized, and the range of the crossbow is relatively shorter; The crossbow is more powerful and has a longer range, but the more powerful it is, the slower it is to load, this is its disadvantage, the effective range of the crossbow is more than two hundred meters, as for the bed crossbow, there are many kinds of ranges, but it is difficult to make, inconvenient to carry, slow to load, and easy to damage, so it is rare to see large-scale equipment.

Whether it is a bow or a crossbow, it is very troublesome to make, the first is to choose the most suitable material, to have toughness, and the hardness can not be too bad, so many bows and arrows are composite bows, which are glued with several kinds of wood, and some of them should be glued to the inner side of the horn or sheep's horn to increase toughness and strength.
