Ryan asked Daddy Moya about the situation of the crossbow in this world, and found that the arrow groove of the crossbow in this world is unenclosed, that is, a long wooden block is connected to the bow body, the length extends to the back of the bowstring, and along the center of the bowstring, there is a semicircular arrow groove carved on the top of the wooden block, which can be used to place the arrow.

The principle of the crossbow is also very simple, pull the bowstring to the buckle position, put an arrow at the arrow groove, and put the tail of the arrow on the bowstring. Then, by holding the switch on the handle, the crossbow will release the buckle, release the bowstring, and shoot the arrow.

The arrows of this world are the same as bows and arrows, the arrows of the arrows are iron, the shafts are wood, and the tails and feathers of the arrows.

However, arrows are not as powerful as bows and arrows, and in general, unless they hit the enemy's fatal point, they hit other parts of the enemy's body not as deep as they imagined, and even, some inferior crossbow bows and arrows could not penetrate even thin-skinned iron armor.

In addition, the crosshair of the arrow also has a slight offset, and the characteristics of the arrow groove structure determine that the crosshair of the arrow must be offset.

Of course, there are still some very good quality crossbows in this world, for example, the broken crossbow that Ryan has on hand, if it is really an heirloom with a history of hundreds of years, as the merchant said, then it is a good crossbow, because a bad crossbow will never be preserved for hundreds of years.

But now the crossbow has no arrow slots, and the bow has a one-third deep crack.

Ryan had already thought that the arrow groove was going to refer to the shape of the barrel of the gun in the previous life, using iron blocks to create a closed arrow groove, and the arrow would refer to the shape of the bullet to create an all-iron arrow.

As for the cracks in the bow?

The jet-black and heavy wooden bow was made of what Ryan really couldn't tell what material it was made of.

Ryan bent his bow slightly, and found that the rift didn't seem to change. Ryan tried to pull the bowstring again, and found that it took almost all his strength to pull the bowstring into position.

"This bow is so powerful, if it weren't bad, maybe it was a good crossbow." Ryan couldn't help but mutter. He carefully observed the cracks in the bow and found that there was a slight unnatural deformation in the cracks, and maybe after hundreds of uses, the bow would be completely broken.

Ryan thought about it, he wanted to replace the bow of the crossbow, but he couldn't seem to think of any good material to replace it.

So Ryan asked Daddy Moya with the crossbow, but Daddy Moya couldn't think of any better material than the existing bow material.

Eventually, Ryan decided to repair the crack in the bow, extend the life of the crossbow as much as possible, and wait until the bow was completely broken before replacing it with a new one.

There are many ways to repair the bow, but Ryan still wants to repair it according to his own ideas, first find a material to make an iron bow.

In this world, there are iron bows made of pure iron, but the elasticity of iron bows is average, not as good as some high-grade wooden bows. According to Daddy Moya, a bow made of pure iron was far inferior to the body of the crossbow, even though it had cracks.

Ryan made two small pieces of iron, one finger's width and two small holes on each side, and drilled two small holes next to the crack in the bow body, then wrapped the two small iron pieces around the bow body in front and back, and finally used a thin iron wire to pass through the small holes in the bow body and the iron sheet, and tightly wound them.

Ryan then pulls on the bowstring of the crossbow to check the condition of the crack in the bow, and finds that the crack is not deformed. This shows that the method used by Ryan is effective. However, the repair of the bow body was not yet completed, and Ryan poured some red-hot molten iron into the junction between the iron sheet and the bow body, and tried to completely bond the iron sheet and the bow body together.

Finally, after the molten iron cooled, Ryan was ruthless, pulling the bowstring of the crossbow hundreds of times, observing some cracks in the bow with each pull. After hundreds of times, Ryan finally came to the answer with satisfaction, the repair was successful, and the crack in the crossbow would not deteriorate in the short term.

The repair of the bow took Ryan two days. Next, Ryan is going to build the Arrow Groove according to his previous idea.

As soon as he first started building, Ryan found that the idea was beautiful, but the reality was cruel.

The lack of tools made Ryan almost give up, and finally had to find a way to persevere.

The most important part of creating an iron arrow groove is to drill holes.

If in the world of Ryan's previous life, the drilling machine used a drill machine to drill a hole, and it would be drilled in two clicks. But in this world, drilling is very troublesome, you need to hold a drill tool in your hand, little by little slowly drilling, and the drilled hole is very irregular, it really can't meet the requirements of the arrow groove.

As a last resort, Ryan had to find a way to improve the drilling technique before building the arrow groove. Fortunately, in the previous life, Rui'an, if nothing else, would only open a few processing equipment, and he knew the shape of various drill bits well.

After countless attempts, the arrow groove was finally reluctantly built, and the smoothness of the arrow groove could not satisfy Ryan, at best it could only be regarded as qualified.

The arrow is much simpler to build, similar to the shape of a pen, the tip of the arrow is very pointed, and the length is because of the weight, after dozens of attempts to fire, it was finally determined to be only half the length of the wooden arrow.

However, the power of the Iron Arrow is much greater than that of the Wooden Arrow, as can be seen from the fact that the Iron Arrow can pierce a small tree pole as thick as an arm.

However, there is a lot of friction between the arrow and the arrow groove, and it makes a very loud grinding sound when fired, which also reduces the power of the arrow. Fortunately, Ryan thought of a way to reduce friction, which was to rub the lamp oil used for lighting into the arrow groove and on the arrows. In this way, the sound is reduced, the friction is reduced, and the power is increased a lot.

Ryan didn't build a lot of arrows, only twenty, because the process of polishing smooth arrows was very time-consuming.

In the end, Ryan thought about it for a moment and decided to cut a blood groove in the arrow, so that it would be easy to bleed after hitting the target. It's a very insidious thing to do, but a lot of people do.

The whole process of repairing the crossbow took Ryan almost twenty days, and it took Ryan a lot of mental and physical strength.

Once the crossbow was repaired, all that remained was to practice archery.

Ryan had a saying in his previous life: sharpshooters are fed with bullets. Similarly, now Ryan needs a lot of archery practice if he wants to become a marksman. However, Ryan was unable to do a lot of practice, because although the crossbow was repaired, it still couldn't support many archery shots, and once the number of times came, it would break completely.

Ryan decided that he would only practice a thousand times in order to get to the target with unmistakable accuracy.

Since the set number of times, then you can't practice aimlessly, you have to practice with your brain.

After Ryan practiced 100 times, he found that the structure of the new crossbow was still relatively difficult to aim.

After thinking about it, Ryan decided to refer to the sights on the guns of his previous life, and installed two vertical aiming rods on the bow body and the tail end of the arrow groove of the crossbow, and then used the principle of three points and one line to aim.

Immediately after that, Ryan fired two or three hundred arrows, carefully adjusting the height of the aiming rod, and finally adjusted the aiming rod crosshair to match the crosshair of the arrow.

At this point, there were only five or six hundred exercises left, and Ryan practiced again and again with an extremely stingy mentality. With the help of the sight, and Ryan's hands are relatively stable, he finally achieved the level of accuracy in the set 1,000 exercises.

The fly in the ointment is that the effective distance of the arrow is about ten meters, and once it exceeds twenty meters, the power and crosshair of the arrow will plummet.

However, this is already very satisfying for Ryan.

With swords, sticks and arrows, Rui Anxin has a kind of pride in killing Buddha and killing God when encountering God.

Everything was ready, and Ryan was a little impatient to go to the academy right away.

After counting the days, there are less than two months left before the registration time of the college.

Ryan pondered for a moment, thinking about whether to go to Skayas City in advance, because he was really not in the mood to strike iron anymore, although he still wanted to earn more gold. He counted all his net worth, about a little more than 14 gold coins, less than 15 gold coins.

Ryan finally decided to go to the Mercenary Guild to see if there were any mercenary missions to Skayas City, and earn some gold coins by taking the mission.
