With the successful convening of the first Tiangong Conference, Chu Xingyun finally conquered Tiangong Island.

From this moment, Tiangong Island, Tiangong craftsmen, and all residents of Tiangong Island were branded by Chu Xingyun.

After the meeting, all the craftsmen dispersed and contacted the 100 sheds they were responsible for to convey the changes in Tiangong Island and Chu Xingyun's opinions.

At the same time, Chu Xingyun again issued an order to select the most outstanding craftsmen from the residents of the island to form a research and development team to study the process of new products.

For the selection criteria, Chu Xingyun set a very high.

The first is to be young, not to be more than fifty years old. Too old craftsmen have solidified thinking and it is difficult to accept new things.

The second is to be knowledgeable, require reading books, strong knowledge, and have the ability to remember.

If these requirements cannot be met, I am afraid that it is difficult to keep up with Chu Xingyun's progress and will be abandoned sooner or later.

Thirdly, it requires excellent skills, painting, techniques, and carving, all of which must reach the level of masters.

If they fail to meet this requirement, they will not be able to cooperate with Chu Xingyun's work. Even if Chu Xingyun has arranged a task, they will not be able to complete it.

In the end, it is the most important thing, that is, be patient, work hard, and continue your long-term work.

After rigorous selection, out of a million people, only thirty-six were selected, none of them.

These thirty-six people are the first batch, the real heavenly works!

The so-called one person counts short, two persons count long.

After passing the Rune Sharp Gold Arrow's runes to these 36 people without reservation, the next test was repeated.

Although Chu Xingyun has completed all the designs, in fact ... that's just a preliminary design drawing.

It is not so easy to implement mass production.

The so-called excellent choice, there is no best, only better!

The most important thing is that the previous blast sharp gold arrow, made of arrowwood, is divided into arrow, arrow shaft, arrow feather, and three parts.

Now, with Arrow Bamboo, the craftsmanship must naturally be improved.

The arrow was canceled directly. After the branches of the arrow bamboo were cut, it became the arrow shaft directly, and brought its own arrow tip.

As for the arrow feathers, it can be replaced with bamboo leaves of arrow bamboo, and its performance is stronger than that of goose feathers.

However, although it sounds simple, the first batch of arrows produced did not meet the requirements.

Abandoning the metal arrow resulted in the shift of the center of gravity of the arrow, the arrow was too fluttering, and the flying attitude was unstable, especially when it fell from the sky, the arrow tip was not downward at all.

Is it necessary to match the arrow tip? But as a result, the cost of the arrow is greatly increased, and the whole process is more than doubled! The production speed is greatly reduced.

After repeated research, the weight of the arrow part must be done, otherwise the head is too light, and the arrow can not exert its power at all.

But the arrow is not necessarily necessary. As for how to solve this problem, it is these thirty-six, the master craftsmen who are really in the name of Tiangong have to study.

For these real talents, Chu Xingyun explained that it is necessary to simplify the process, reduce costs, and increase output on the basis of ensuring quality and performance.

After a lot of tests, finally ... thirty-six days of artisans jointly identified a set of plans.

Everything else remains unchanged. The only thing that has changed is to insert a lead shot into the bamboo pole at the tip of the arrow bamboo to adjust the center of gravity of the arrow.

The stuffed lead shots have many uses.

First of all, because the tip of the arrow bamboo is made by diagonally cutting the bamboo pole, it has a cavity. After being plugged with lead shot, it can avoid debris from entering it and affect the performance of the arrow.

Secondly, the weight of the lead shot is very large, and it is very soft, making it easy to adjust the center of gravity of the arrow.

Thirdly, although the lead shot is soft, it is also a metal after all. Under the inspiration of the sharp gold array, it can excite sharp arrows.

Finally, when the arrow shoots into the flesh, it will burst, causing lead shot to enter the enemy's body.

Because lead is relatively soft, all kinetic energy is often released after hitting the body. Specifically, the warhead is severely deformed or even ruptured, resulting in a flared cavity in the body tissue. The wound area is hundreds of times the projectile cross-sectional area.

Coupled with the momentary damage to the body's blood circulation system, resulting in huge pressure ... unimaginable.

The suffering of the wounded is not limited to this. If all the fragments of the projectile are not taken out of the wound, it will cause lead poisoning.

Even if there are few pieces of fluke, they are taken out through surgical operation. After the projectile is shot into the body, some pieces of clothing will be brought into the wound and cause infection ...

It can be said that a small lead shot directly increased the lethality of the blast sharp arrow by ten times!

Although the speed and penetrating power have not changed, the addition of lead shots has made the arrow's lethality extremely terrifying.

Although only a lead shot was inserted at the tip of the arrow, this blast of sharp gold arrow instantly changed from a sharp weapon to a murder weapon! Extreme brutality.

If it is a war with the same kind, Chu Xingyun would rather lose, not wanting to use this weapon.

However, if the enemy feeds on humans and is dedicated to exterminating the demon clan, then Chu Xingyun does not mind using any weapons and means.

After confirming the final manufacturing process, with the order of Chu Xingyun, the whole Tiangong Island began to get busy.

If it is completely let go and produce with full force, one hundred thousand master craftsmen, two hundred thousand assistant craftsmen, four hundred thousand craftsmen apprentices, three hundred thousand old women and children, together with one million craftsmen, one day can produce 100 million Cut arrow.

Of course, the arrows produced in this way must be crudely manufactured. Although they can be shot, it is difficult to guarantee what kind of arrows will fly.

Bamboo is not as straight as wood, and it has some arcs, so if one is not handled well, the arrows will draw arcs when they fly out, and they cannot hit the target at all.

Moreover, the current production, but the blast sharp gold arrows, need to accurately characterize the runes, which is simply not accurately completed by apprentices and assistants.

To ensure the quality of the arrows, to ensure that each blast sharp gold arrow is straight and accurate, and perfectly trigger the runes, only the 100,000 master craftsmen can make a guarantee in person.

With full cooperation, 100,000 work sheds are used as a unit.

Among the four apprentices, one of them is responsible for finding and collecting bamboo branches, looking for the most straight bamboo collection.

The second apprentice is responsible for transporting the collected bamboo branches back.

The third apprentice is responsible for screening the bamboo branches collected, and removing the unstraight and defective bamboo branches.

The fourth apprentice is responsible for repairing the bamboo branches and cutting them into rough arrow shafts.

Two assistant craftsmen, one of them is responsible for cutting qualified bamboo branches, cutting out the tip of the arrow, and inserting the arrow feather.

Another assistant craftsman is responsible for stuffing lead shots and adjusting the center of gravity of the arrows.

After all this was completed, the arrows were handed over to the master craftsman for the characterization of the runes.

After depicting the runes, a blast of sharp gold arrows was officially completed.

Each blast of sharp gold arrows needs to pass through the hands of four apprentices of craftsmen. After two assistant craftsmen make them, the master craftsmen will engrave the runes.

The finished arrows are handed over to the old women and children in the work shed, and they will do the final inspection and confirm that everything is ok, then polish, print, bale and decorate. Blasting sharp gold arrows, ten bundles, bundled with bamboo rope, handed over to the warehouse for storage, and exchanged for work points.
