Ruian asked Moya about the situation of the crossbow in this world and found that the arrow groove of the crossbow in this world is non-closed, that is, a long piece of wooden block is connected to the bow body, and the length extends to the back of the bow string. On the wooden block is engraved with a semicircular arrow groove in the center of the bow string, which allows the arrow to be placed on it.

The principle of a crossbow bow is also very simple. Pull the bow string to the buckle position, place a slow arrow at the groove, and put the tail of the slow arrow on the bow string. After that, just hold the switch on the handle, the crossbow will release the buckle position, release the bow string, and shoot the slow arrow out.

The sluggish arrows in this world are like bows and arrows. The arrows of the sluggish arrows are iron heads, the shafts are wood, and the tails are also arrow feathers.

However, the slow arrow is not as powerful as the bow and arrow. Generally speaking, unless it hits the enemy's fatal key, it will not be as deep as you imagined in other parts of the enemy's body. Even some inferior crossbow archers cannot penetrate even thin iron armor.

Furthermore, the slightest star of the slow arrow also has a slight deviation, and the characteristics of the arrow groove structure determine that the slightest star of the slow arrow must have an offset.

Of course, there are still some very good quality crossbows in this world. For example, if the broken crossbow on Ruian is really a family heirloom that has a history of hundreds of years as the merchant said, then it is a good crossbow, because bad crossbows will definitely not be preserved for hundreds of years.

However, now this crossbow has no arrow grooves, and the bow body has a crack of one-third deep.

Ruian had already thought about it. The arrow groove was intended to refer to the shape of the barrel of the gun in his previous life, and use iron blocks to create a closed arrow groove, while the arrow was used to refer to the shape of the bullet to create a fully iron arrow.

As for the cracks in the bow body?

The dark and heavy wooden bow body was really hard to tell what material it was made of.

Ruian bent his bow gently and found that the crack did not seem to change. Ruian pulled the bowstring again and found that it was almost necessary to use all the strength of his body to pull the bowstring to the buckle position.

"This bow is really powerful. If it is not broken, it might be a good crossbow." Ruian couldn't help muttering. He carefully observed the cracks on the bow body and found that there was a little unnatural deformation at the cracks. Maybe it would be used hundreds of times and the bow body would be completely broken.

Ryan thought for a while and wanted to replace the bow of the crossbow, but he couldn't seem to think of any good materials to use instead.

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

Finally, Ryan decided to repair the cracks in the bow body and extend the life of the crossbow bow body as much as possible. When the bow body is completely broken, replace the new crossbow.

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

In this world, there are iron bows made of pure iron, but the elasticity of the iron bow is average and not as good as some high-end wooden bows. According to Dad Moya, the bow body made of pure iron is far inferior to the bow body of this crossbow, although it has cracks.

Ruian created two pieces, one with a finger-wide small iron piece with two small holes on both sides, and drilled two small holes next to the crack of the bow body, then wrapped the two small iron pieces in front and back around the bow body, and finally used thin iron wire to pass through the small holes of the bow body and the iron piece, and tightly wrapped it.

Then Ruian pulled the bow string of the crossbow to check the condition of the cracks on the bow body, and found that the cracks were not deformed. This means that the method Ruian used was effective. However, the repair of the bow body has not been completed. Ruian poured some red iron into the connection between the iron sheet and the bow body, striving to completely bond the iron sheet and the bow body.

Finally, after the iron was cooled down, Ruian made a ruthless heart and pulled the bow string of the crossbow up to hundreds of times. Every time he pulled it, he observed some arch cracks. After hundreds of times, Ruian finally got the answer with satisfaction. The repair was successful and the cracks of the crossbow would not deteriorate in the short term.

The repair of the bow took Ryan two days. Next, Ryan would build an arrow groove according to his previous ideas.

As soon as he started building it, Ryan discovered that ideas are beautiful, but reality is cruel.

The lack of tools almost made Ryan give up, and in the end he had to find ways to persevere.

The most important thing in creating an iron arrow groove is drilling.

If in the world of Ryan's previous life, drilling holes with a drilling machine will be done in two straight lines. But in this world, drilling holes is very troublesome. You need to hold a drill bit tool in your hand and drill slowly bit by bit. Moreover, the holes drilled are very irregular and cannot meet the requirements of arrow grooves.

As a last resort, Ruian had to find a way to improve the drilling technology before building the arrow groove. Fortunately, Ruian in his previous life had no other skills, so he could only open a few processing equipment and knew the shapes of various drill bits well.

After countless attempts, the arrow groove was finally reluctantly created. The smoothness in the arrow groove could not satisfy Ruian, and at most it could only be considered qualified.

The creation of a slow arrow is much simpler. It is like a pen. The tip of the arrow is very sharp. The length is due to the weight problem. After dozens of attempts to launch it, it was finally confirmed that it was only half the length of a wooden slow arrow.

The power of the iron arrow is much greater than that of the wooden arrow. This can be seen from the fact that the iron arrow can penetrate a small tree pole as thick as an arm.

However, the friction between the slow arrow and the arrow groove is very strong, and it makes a very high friction sound when it is launched, which also reduces the power of the slow arrow. Fortunately, Ryan thought of a way to reduce friction, which is to rub the lamp oil used for lighting on the arrow groove and the arrow. This way, the sound is reduced, the friction is reduced, and the power is increased a lot.

Ryan did not create many scattered arrows, but only built twenty, because the process of polishing the smooth arrow body was very time-consuming.

At the end, Ryan thought for a moment and decided to open a blood groove on the arrow to facilitate blood loss after hitting the target. This is a very sinister way, but many people will do it.

The entire process of repairing the crossbow took almost 20 days, and even more consuming a lot of mental and physical strength.

After the crossbow is repaired, the remaining problem is to practice archery.

There was a saying in Ryan's previous life: The sharpshooter was fed with bullets. Similarly, if Ryan wants to become a sharpshooter, he needs a lot of archery practice. However, Ryan cannot do a lot of practise because although the crossbow has been repaired, it still cannot support many archery times. As long as the number of times is reached, it will completely break.

Ryan decided to only do a thousand exercises himself to strive to hit the target accurately.

Since the number of times is set, you cannot practice aimlessly, you must practice with your brain.

After Ryan finished a hundred exercises, he found that the structure of the new crossbow was still difficult to aim at the target.

After thinking, Ruian decided to refer to the sights on the guns in his previous life, install two vertical sight rods at the bow body of the crossbow and the tail end of the arrow groove, and then use the principle of three points and one line to aim.

Immediately afterwards, Ryan shot two or three hundred arrows, carefully adjusted the height of the aiming rod, and finally adjusted the aiming rod's sight to the same as the slow arrow's sight.

At this time, the remaining exercises were only five or six hundred times, and Ryan practiced again and again with an extremely stingy mentality. With the help of the sight and the stable hands of Ryan, he finally achieved the level of accuracy of 90% of the ten shots in the set thousand exercises.

The only drawback is that the effective distance of the slow arrow is about ten meters, and once it exceeds twenty meters, the power and sight of the slow arrow will plummetly.

However, this already made Ryan very satisfied.

With the sword stick and the arrow, Ruian felt a sense of pride in his heart of meeting Buddha and killing Buddha, and encountering gods.

Everything was ready, and Ryan couldn't wait to go to school right away.

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

Ryan calculated and wondered whether to go to Skayas City in advance, because he was really not in the mood to make another iron, although he still wanted to earn more gold coins. He counted his entire net worth, about 14 gold coins, and less than 15 gold coins.

Ryan finally decided to go to the Mercenary Association to see what mercenary missions to Skayas City, and take over the mission and earn some gold coins.
