A few days later, seeing Yang Yifei successfully integrated into the group and began to lead the disciples of Pili Temple to enter production and carry out training for gunpowder workers, Chen Jinnan also felt relieved and prepared to leave.

After all, as the leader of the helm, the Tiandihui still needs to be at the helm, and it is impossible for him to stay here forever.

After Yang Yifei sent him to the beach, he pulled him aside and said, "Master, Pili Hall has now been put into production. It will require a lot of materials and materials in the later stage, and coal needs to be reserved more. Now it is time to get another treasure to avoid the situation of capital breaking in the world."

Chen Jinnan was excited and said happily: "That's true. Although Emperor Yuan of Liang has a rich treasure, we have purchased various materials in the past six months, and 30% of the treasure has been spent. After that, we will form an army and train the army, we still need a lot of food and salary, which may be short of money."

Yang Yifei nodded, approached Chen Jinnan's ear, and whispered: "The treasure hiding place of the Qing Dynasty's Tartars was located outside the pass, at the intersection of Luding Mountain, the Emuer River and Heilongjiang. The head of the helm brought a group of disciples to the nearby area for a brief search, and he would definitely find the place."

Yang Yifei deliberately avoided other people in the Pili Hall because he was afraid that someone would not be able to resist the temptation of the treasure and did something that he regretted, so he only told Chen Jinnan the location.

At that time, Chen Jinnan will choose trustworthy brothers and go out of the gates to get out treasures, but even those who can trust will not easily reveal their words before reaching Luding Mountain. It will be fine if he arrives at the place and then speaks it out.

Chen Jinnanqiang suppressed his joy and nodded, "I have recorded it. When I go back this time, I will arrange people to go and get out the treasure as soon as possible. You should also speed up the acquisition of Shenlong Island. It is safer to hide the treasure overseas."

"As for coal, we have secretly taken a coal mine in Shanxi and are trying to find several other places, so there will never be a shortage of coal."

Yang Yifei said with satisfaction: "That's good, don't worry, Shenlong Island, you don't need to be too many. As long as you can build ten cannons and more than a hundred muskets, it's more than enough to take down Shenlong Island, half a year to ten months."

Chen Jinnan slapped Yang Yifei on the shoulder with a high spirit and said, "Okay, our brothers will perform their own duties and work together. I believe that it will not take long before we can declare war on the Tartars."

Yang Yifei nodded heavily, then clasped his fists and smiled: "I wish the leader a good journey."

...

Chen Jinnan left, took most of the ships away, and went to the outside of the pass to transport treasures to use a boat. He only left four large ships, which were used for the external contact of Pili Hall, and there were many small boats in Diaoyu Islands, which were enough.

After half a month of training, the disciples responsible for manufacturing gunpowder and thunderbolt bombs have already made a clear understanding of various precautions and taboos and have begun to officially start production.

A total of 120 people who made gunpowder and thunderbolt bombs were led by Xu Tianchuan and others from Aoki Tang as the leader. Each of them brought five disciples as a group, and divided into six workshops to work, including four workshops responsible for synthesizing black gunpowder, and two workshops responsible for making thunderbolt bombs.

These six workshops are very spacious and the groups are far apart. In this way, even if an accident occurs, the losses can be minimized. Yang Yifei attaches great importance to safety work and strives to do what he can do to the limit.

It is related to their own life and the great cause of heaven and earth. These disciples are very careful when doing homework, striving to do every step perfectly and ensure that there is no accident.

In the entire Pili Hall, and even the entire Tiandihui, only these hundred people knew the perfect formula ratio of black gunpowder. Of course, Yang Yifei did not hide anything about Xu Tianchuan and others, but they were required to keep it strictly confidential and not to be disclosed.

Xu Tianchuan and others and their disciples all knew that the perfect formula ratio of black gunpowder was the key to ensuring their transcendent status, so they would naturally not say it out, because if everyone understood it, they would be worthless if they had no special features.

The thunder bomb began to be produced in large quantities, and the specifications were all made of three or two black gunpowder, and the power was just as good as a grenade. However, because there was no grenade shell, it was much smaller. After mixing some broken porcelain pieces, the lethality was not much smaller than that of the grenade.

In addition to gunpowder and thunderbolt bombs, there are also fuses that must be made, which is an indispensable thing for artillery.

However, it is much easier to make a fuse. First, put the linen into boiling vinegar and cook it. Take it out and dry it and cut it into a uniform width cloth strip. Then sprinkle gunpowder in the cloth strip, and finally roll it into a rope shape. Wrap the gunpowder in the rope, and then become a fuse.

This work is not dangerous, both men and women can complete it. Each person can use a bamboo tube of gunpowder to rub out a roll of fuse, because there is too little gunpowder and there will be no accidental explosion.

With the fuse, flowering bullets can also start production. The so-called flowering bullet is an iron ball filled with black gunpowder, insert a fuse, and then seal the hole.

When firing, a partition needs to be placed in the barrel to separate the gunpowder from the flowering bullet. When igniting the fuse of the launching medicine, the fuse of the flowering bullet must also be ignited at the same time.

The length of the fuse needs to be calculated through multiple real-time tests to obtain the most appropriate length.

After the first musket was made, Yang Yifei decided the amount of the paper shell bullet after testing, and the paper shell bullet also began to be put into production.

Of course, the principle of paper shell bullets can not only be used for muskets, but also for cannons.

Put a certain amount of gunpowder into the flammable material in advance to form a bag or block. Just stuff as much gunpowder when firing the gunpowder, and then use the tamper to compact it, the speed of fire will be faster.

Therefore, after half a month passed, with the blacksmiths' pursuit of excellence, the first gun barrel was successfully cast and installed with the base, Yang Yifei began the test of artillery loading under the attention of all his disciples.

The leader of the blacksmith of the Tiandihui is the inheritance of the craftsmen of the Shenjiying of the Ming Dynasty. He has superb skills. With the alloy formula provided by Yang Yifei, the cast gun barrels are dense and have no impurities, so there will be no bees in which the gun barrels cast by the Tartars are densely covered with bee-eyed eyes and are very easy to explode.

The amount of artillery charge is related to the adjustment of the large-range range of the artillery. Small-range correction can be achieved by adjusting the elevation angle of the artillery. Adjusting the large-range range requires controlling the charge to achieve.

After testing and calculations, Yang Yifei divided the charge into five levels. For each additional charge of one level, the range of the cannon will be increased by 200 meters.

Therefore, the range of No. 1 loading is 200 meters, and the range of No. 2 loading is 400 meters, until No. 5, also known as the full loading, with a maximum range of one thousand meters.

So how did Yang Yifei test the approximate distance without a rangefinder or a military telescope with rangefinder function?

It is very simple. The "eye-skipping distance measurement method" commonly used by artillery soldiers during the War of Resistance in later generations is the scene where artillery soldiers look at the target with a thumbs up and narrow one eye.

At that time, various ranging tools had not yet developed, so the artillery used this method to measure ranging.

By evaluating the size of the target and combining the similarity triangle principle, the approximate distance between the target and us can be calculated.

This method is to multiply the width of the measured object by ten, and then the distance from the standing point to the target is obtained based on the interval between the two pupils is about one tenth of the length of your arm.

The specific method is: raise your right arm horizontally, your thumb is vertically upward, your arm is perpendicular to your body, close your left eye, rotate your waist, aim (block) the target with your thumb. At this time, the right eye, thumb, and target are in a line.

Then, the body and arms do not move, close the right eye and open the left eye. At this time, you will see the target appear on the left side of the thumb, with a lateral distance, estimate the size of the target, and judge the lateral distance between the target and the position pointed by the thumb based on the size of the target.

Multiply this lateral distance by ten, and what you get is the distance from the target.

Although this distance measurement method is rough and has errors, the error is not large. If there is no effective equipment, this method can only be used.
