As we all know, the greatest power of the flowering bullet is the debris attack generated during the explosion, which is like a celestial girl scattering flowers.

Xu Changqing was not too worried about the explosive power of the gunpowder, but was very worried about the bamboo tube shell.

It should be noted that the power of gunpowder is ultimately limited after all, without standardization, and even more so it cannot be energized.

When gunpowder explodes, destroying the bamboo tube shell, how much can the power of the heavenly woman scattering flowers show and how much lethal it can cause to the enemy? This is the issue that Xu Changqing is most concerned about.

Master Zhang Jiu has recovered a lot at this time, and he is a few years younger.

To be honest, the pressure on him was really a bit huge when Xu Changqing placed such high hopes.

He smiled and said with a hurry: "General, this matter really stumped me at the beginning. The main reason is that the bamboo is thick and has been pickled, and it is very tough. At the beginning, many gunpowder cannot be blown up, and even if it can be blown up, the effect of the sand and gravel inside is very poor. But if the bamboo is not pickled and dried, it may be more trouble. We have worked hard these days and finally came up with a solution, which is to polish the bamboo tube thinner..."

As Zhang Jiuye’s narration was made, Xu Changqing quickly understood what he meant.

People definitely didn't suffocate to death by urine.

Zhang Jiuye and his friends use the simplest, but also the most practical method.

That is to polish the inside of the bamboo tube smoothly, so as to be as thin as possible, then stuff some soft dry leaves into it as filling, and stuff some sand and gravel to ensure the gathering of gunpowder in the oil paper, and at the same time, attach a layer of lethality.

In this way, once an explosion occurs, these gunpowders can exert their power to the greatest extent.

Even if this cannot meet Xu Changqing's most ideal expectations, it is already an excellent effect.

However, the efficiency of producing bamboo-type flowering bullets in this way will be reduced and more manpower is required.

Xu Changqing immediately gave Zhang Jiuye a reassurance and would immediately mobilize a group of people from Hope Island to specially prepare bamboo tubes.

Mr. Zhang Jiu also made him thank him very much.

Afterwards, Xu Changqing talked a lot with Zhang Jiuye, including some ideas about explosive packs.

Mr. Zhang Jiu nodded frequently and said that he would immediately enter the R&D program.

Xu Changqing did not aimlessly for a larger weapon like the explosive pack, but had already planned it.

It’s a bit about the use of “mine warfare” in our army in later generations.

Since discovering Zhang Dagong's specialty, Xu Changqing has this thought.

The same old saying: "No matter whether it is a white cat or a black cat, a good cat is the one who can catch a mouse!"

If it were just Xu Changqing himself, the effectiveness of these things would not be too good. After all, Xu Changqing was still too thin and lacked positive abilities, which made it difficult for Xu Changqing to truly implement even if he had many advanced ideas and weapons that transcend this era.

However, with the support of Cao Bianjiao and Wang Pu, things are different!

As long as the time is right, Xu Changqing has the ability to go deep into the hinterland of the battlefield and carry out some precise operations!

The explosive pack is much simpler than a flowering bullet. The key is to lay the fuse and the gathering of gunpowder, but this is not difficult for veterans like Zhang Jiuye.

The only thing to worry about is that the amount of gunpowder must be reasonably proportioned. After all, Xu Changqing's gunpowder stock was not enough at this time, only seven or eight thousand kilograms could be used.

…

There are many problems on the flowering bullet, and further deepening and improvement are needed. The main reason is that it is too heavy and throwing is probably difficult, but on the side of the catapult, Li Zhu was particularly smooth.

The main reason is that the catapult cart is simple and has solid beef tendons as support. Li Zhu and his team only need to put more force step by step.

At this time, in more than two days, more than fifty catapults, or "projection cars" and "big slingshots", have been built.

Xu Changqing asked Li Zhu and the others to try it with a bamboo tube filled with sand, and the effect was quite gratifying.

This kind of bamboo tube of about 70 to 8 pounds can generally project 170 to 80 or 200 meters.

Li Zhu hurriedly explained: "General, the main thing is that the beef tendon has just been opened.

(This chapter is not finished, please turn the page)

It was a little astringent when it was really pulled apart, and it wouldn't be a problem if it was farther apart."

Xu Changqing nodded.

This distance is almost the same.

If pitchers who throw flowering bullets still need time to train and flowering bullets still need to be refined, carpenters like Li Zhu can be directly treated as "artillerymen".

In fact, there are still problems with the design of the flowering bullet fuse. The best result is that it is ejected in the air. When it is about to land, it explodes directly in the air, forming the maximum lethality.

However, things in the world cannot be so perfect.

If there is a similar opportunity, Xu Changqing plans to use a throwing cart to throw the flowering bullet directly!

After all, the two countries are carrying the tripod, and China is a traditional farming nation. As long as Hong Chengchou has no water in his mind, he will definitely not fight head-on with the Qing army, and positional warfare is still the mainstream!

This gives Xu Changqing room to fully utilize his/her performance!

…

Although I still want to spend more time on Shark Island and continue to discuss something with Mr. Zhang Jiu, time is tight at this time, so Xu Changqing can only leave first.

However, Mr. Zhang Jiu has been completely brainwashed by Xu Changqing. This old man is working hard, so there should be no big problem.

After all, their families are in control of Xu Changqing. If they dare to cheat, they will not be able to bear the consequences.

Not to mention, they don’t know how to water at all. They are trapped on this deserted island. Without Xu Changqing’s order, it is basically impossible to leave.

In the evening, Xu Changqing boarded the warship again and headed to Hope Island.

Li Zhu originally wanted to leave with Xu Changqing, go back to Hope Island to see his wife and children, and show off the reward of twenty taels of silver given to him by Xu Changqing.

But Xu Changqing's warship was too small after all, and it was full of supplies. He couldn't load so many catapults. This guy could only endure it for another day. When tomorrow Xu Changqing sent a ship to pick them up on Hope Island.

I rushed back to Hope Island and just came out at eight o'clock.

At this time, the huge Hope Island was no longer the desolate thing it was before. There were various sheds, simple houses, and fires burning, illuminating the hopeful faces around them.

From a distance, the stars look like a prosperous city.

Xu Zhong, Ma Luan, Zhang Hongqiang, Uncle Hong, Uncle Guang and others received the news and quickly came to greet Xu Changqing.

Xu Changqing has been very busy these days, but they are even busier, almost without touching the ground, and are working full loads for twelve hours a day.

Looking at the regular camp, everyone looked a lot of weight loss, Xu Changqing felt a little moved and felt a little distressed.

Master Zhongtang is worthy of being an expert among experts. That famous saying is definitely a classic in management science: "Don't you need to be nepotist, do you need to be a human being?"

The group was about to report on the work in a hurry, but Xu Changqing interrupted them and said with a smile: "It's all my men, why are you so anxious? Come on, let the fire soldiers cook a few dishes first, let's talk while talking!"

…

The blazing bonfire crackled, and in the simple official hall in the center of Hope Island, Xu Zhong and others took turns to report to Xu Changqing.

The main thing is the recent construction of Hope Island, the process of migration from Shark Island, as well as the various operations on the island, materials and fishing conditions, as well as the mooring and resettlement of fleets, etc.

To be honest, with Xu Zhong overviewing these government affairs here, it is more organized than Xu Changqing.

After all, Xu Zhong is the second housekeeper of the Xu family. He has been engaged in this complicated management work for twenty or thirty years, and there is no way to say anything about his experience and means.

However, if it involves the overall situation and future plans, he will not do it.

However, what Xu Changqing needs now is a person with strong execution ability and calm management ability. As for planning and future, including leading, why do you need others?

At this time, I hope the island has basically stabilized.

Several fishing spots were also set up on the island, and the material storage was established. Even if they were not as easy as catching sharks as Shark Island, the auxiliary soldiers who led the team to catch fish were all veterans, so there was no big problem.

Next to the gentle reef group in the east of the island, in a slightly deep harbor

(This chapter is not finished, please turn the page)

The wharf was also built.

Although many warships and bamboo rafts are moored are a bit crowded, as long as there is no major storm, the problem should not be big.

Seven or eight miles southeast of Hope Island, there is a small island without fresh water, with a good harbor inside. Even if a storm occurs, as long as you go over and avoid it in advance, there will be no big problem.

As for the parking of bamboo rafts, it is much simpler. It is a group of off-road vehicles on the sea, and it is parked directly on the reef.

After dinner, the report was almost over. Xu Changqing asked the others to go back and rest first, leaving only Xu Zhong himself behind.

The gentle smile that Xu Zhong had always maintained before quickly disappeared, and he looked at Xu Changqing worriedly: "General, Ning Yuan, have you gone to war?"

Xu Changqing was not surprised that Xu Zhong could guess Ning Yuan's general trend.

If you can't guess, it will disappoint Xu Changqing.

"call."

Xu Changqing exhaled a long breath of turbid air, but looked at Xu Zhong very calmly and said, "Uncle Zhong, the governor swore to go to the battle early this morning. I will set off for the Jinzhou frontline tomorrow morning!"

"this……"

The old tobacco pipe in Xu Zhong's hand almost fell to the ground. After a moment, he came back to his senses and hurriedly said, "General, this is so urgent, then..."

Xu Zhong wanted to say something, but Xu Changqing smiled and waved his hand, "Uncle Zhong, I know what you mean. What a pity. The general situation is settled, and we can only obey the general situation!"

As he said that, Xu Changqing smiled and patted Uncle Zhong on the shoulder: "Uncle Zhong, you don't have to worry too much. This time, my Ming Dynasty is not small, and it is unknown who will win to death! Moreover, this is a good opportunity for me and our Xu family!"

Xu Zhong looked at Xu Changqing, who seemed to be in control of everything, how could he not understand what Xu Changqing meant?

The heart hanging in my heart is gradually calming down.

God is so pitiful. It’s really a great ancestor who has opened his eyes. The Xu family has a queen.
