"Lao Peng, put down the work in your hand first, help the officials make the objects on the map, the dimensions are clearly marked, no matter what method is used, be sure to make this thing not broken and as light as possible, and send it to Daao after it is done."

With hope, there is motivation, Hong Tao's sleepiness is immediately gone, he went into the study alone and didn't even eat breakfast, walked and painted until noon, and then went to the back garden with a rice bowl to find Peng Da who was carving patterns on the crib.

The drawing really looks like a hornet's nest, but it is much elongated, with a hexagonal cylinder on the outside and dozens of small cylinders inside. And it's not one size, it's two, the large one is more than two meters long and the thickness of the embrace; The small ones are just over a meter long and have thigh-thick skins.

There is also a set of drawings that draw arrows, and the specifications are also two, the length and thickness of which match the two hornet's nests. The most obvious difference from ordinary arrows is that there is an extra bamboo tube under the arrow, which is not simply tied to the arrow shaft, but passes through the middle of the arrow shaft.

This is Hong Tao's new type of rocket improved on the basis of a swarm of bee arrows in the Ming Dynasty, if the gunpowder cartridge is tied to the arrow shaft, it is bound to destroy the balance and aerodynamic form of the arrow, and it can be much better to pass through the middle of the bamboo tube.

In addition, this powder cartridge also plays the role of a piston, and the small cylinder on the sub-bamboo cylinder is similar in size to the hornet's nest, slightly thinner, and can just block the small cylinder when loading.

When the fuse is ignited, the gas emitted from the bamboo tube will expand extremely, and when it encounters a blockage, it will produce high pressure, increasing the initial velocity of the arrow. Moreover, this bamboo tube can also control the attitude of the arrow in the cylinder, always maintaining the center position, and in principle, it can reduce the dispersion rate. As for the actual effect, who knows, try it.

Peng Da is the first batch of craftsmen to follow the horse, from the beginning of the flying feather equipment and the horse contact, for this kind of whimsy has long been accustomed to this kind of whimsy, the horse said how to do it, in addition to the technical details and effect requirements, do not ask a word of superfluous, the ability to understand has been significantly improved.

After explaining to Peng Da, Hong Tao's lunch was basically finished, put the empty bowl away, hugged Chen Niang and took two female secretaries and a bodyguard to the Water Tiger Wing Military Camp in Jinmingchi.

"What are the lieutenants going to do, and why are these supervisors and internal supervisors here?" Before he entered the barracks, he saw the figure of the crown, and after seeing Hong Tao, he pounced on him like seeing a savior, his face was full of horror and his mouth was full of questions.

The soldiers were just about to have breakfast, when suddenly a squad-leader came, with a team of forbidden troops and a few ox carts to block the barracks, and he was not allowed to enter or leave, nor did he say what he was going to do, but he was scared enough to choke the crown. It wasn't until Hong Tao and his party appeared that he realized that this time it must have been the trouble of the horse again, and he ate the melon and fell.

"Brother Wang, don't panic, I just want to help Your Majesty make something, this thing is not secret, and it is not suitable for making in the palace. Your Majesty asked where in Kaifeng City was safe and safe, and I was the first to recommend Brother Wang's Water Tiger Wing Military Camp to Your Majesty. If Brother Wang thinks it's not suitable, I'll let them move to Ugin Shop. ”

Hong Tao said that this is a touching thing, but not a word of the content is true, and the middle-aged man dressed as a eunuch who happened to go out to greet him grinned. He obviously knew the inside story, but he couldn't say anything, so he could only watch the horses turn around the water tiger wings.

"Suitable! You and I are like brothers, why can't we do it! Everyone in this camp is under the orders of the captain, and there is no complaint! As soon as he heard that it was the emperor's approval, the square face of the crown almost grew with laughter, and the armor clanged.

I can't ask for such things that go straight to heaven, and of course I can't push them out. The colt is really a friend, and if he says more than half a sentence at a critical time, it is enough for a middle- and lower-level officer like himself to struggle for half a lifetime.

"Then please ask Brother Wang to vacate two military tents for me first, and no one within fifty steps of the surrounding area shall approach. The hands of the people will not bother the brothers, and Your Majesty will arrange it freely. ”

Hong Tao didn't mean to cheat the crown, just to save trouble. If you explain the process of configuring black powder with him clearly, plus answer questions, you won't be able to figure it out in two hours. What I lack now is time, and after twenty years, the emperor will personally come to review the results, and every minute must not be delayed.

“…… I understand, I understand! The crown followed Hong Tao's gaze and almost bit his tongue off.

The labor that the horse said was actually the forbidden army of all classes, which is too bullish! These squads that came out of the palace were the elite of the elite of the forbidden army, and they were all selected from the noble family, and any one of them could be the nephew of the privy envoy. Now that I'm going to use the horse as a coolie, do you dare to ask the following questions, what should I do now?

"On the other side, is Huang Zhonggui Huang?" Taking away the crown, Hong Tao arched his hand at the eunuch who was standing a little farther away.

If Pei Ying hadn't lied to herself, this person should have been Huang Huai'an, the chief attendant of the Eight Divisions who designed the Great Ao. In the morning, after Pei Ying's decree, he didn't resist, but unfortunately he was invalidated. It's always okay to make a few small requests, but this time Pei Ying agreed, and transferring Huang Huaian to himself as a deputy is one of them.

"Lord Du Wei has killed the villain, Lord Pei has a word, let the villain follow the adult's side, and everything is sent regardless of the reason." Huang Huai'an is more like a eunuch than Pei Ying, because he is young, he is in his thirties, his complexion is fair, and his voice is thin and soft.

"Since Pei Zhonggui has already ordered, I won't say more, the time is tight and the task is heavy, Lord Huang first asked the forbidden soldiers to carry the goods on the car to the military tent and wait, I will come when I go."

If it were in normal times, Hong Tao would definitely have to talk to this master who designed the dry dock, but now he really has no time, and he still has the drawings of the new arrow cluster in his arms, so he has to quickly send it to Wu Si to let him create a few more of each, and then hand it over to Peng Da to try to produce arrows of different weights and lengths, and I don't know which one is suitable in the end.

The ox cart of the forbidden army was carrying charcoal powder, sulfur and saltpeter of the royal standard, and Hong Tao did not have the time to make his own raw materials, let alone use the black powder prepared by the forbidden army. That thing doesn't work well except as a smoke bomb.

Black powder has been prepared many times, but it has never been formulated with rocket fuel grade, and the burning speed of that thing is required to be slower than that of propellant, the more balanced the better, and what ratio to use has to be tested over and over again. It may be tried ten times, or it may not be tried a hundred times, and only God knows how long it will take.

After the work on Wu Si's side was arranged, the forbidden army had already put away several barrels of charcoal powder, sulfur powder and saltpeter powder classification codes, but no one was allowed to enter the military tent that finally configured the finished product. Not only can you not enter, but you have to stay away from thirty paces, and if you don't shout that anyone dares to take a step forward, the soldiers of the forbidden army will shoot them with arrows, this is a death order.

"Don't the officials want Lian'er to be a secretary?" As soon as she heard that only her own officials and a eunuch could enter the military tent, Lian'er's mouth immediately pursed, and her eyes were still full of mist.

In the past, officials didn't carry anything behind their backs, usually officials were busy with their own work and recorded by themselves, why did it change this time, the simplest explanation is that they no longer trust themselves.

"Shhh...... You girl, the busier you get, the more messy you get! It's not that the officials won't let you in, it's that it's dangerous and abnormal, and the people who enter don't need to be careful. The official feels sorry for you, obedient. ”

Originally, Hong Tao wanted to educate her with a straight face, but when he saw Lian'er's expression, his heart softened again. The little girl is also well-intentioned, so she can't break her heart, so let's scare and scare.

"Officials are not afraid of Lian'er, Huang Zhonggui is an internal prisoner, concubines and concubines are served, Lian'er is not so expensive, the slave family wants to go with the officials!"

Unexpectedly, Lian'er was quite stubborn, and while speaking, she took out a small notebook from her skin and walked into the military tent with her head held high, with a bit of generosity and righteousness.

“…… Lord Huang is a strange thing, all blame my lady for being too arrogant and unruly on weekdays...... "This makes Hong Tao very embarrassed, although what he said just now is frightening, but some of the content is true, such as not being able to wear clothes.

Although it is black powder, once it is ignited, the power cannot be underestimated, and it can't be burned if it can't be blown up. Clothing generates static electricity and must be removed. The gunpowder workshops of the Golden River Empire were all this rule back then, and they were so cautious that they had blown up once, so it was impossible to be too careful.

If it's just herself, Lian'er will enter when she enters, isn't there still an outsider. Although the little girl and herself are not husband and wife, she is already her own woman in her heart, so she strips naked and lets outsiders see it, even if she is happy and she is not happy.

"What a heroine among women! Miss Lian'er is right, she is an internal official, and there is no difference between men and women, so Lord Duwei can rest assured. Huang Huai'an didn't seem to have the intention of quitting, first stretched out his thumb and praised it, and then stretched out his hand and made a gesture of please.

"Sister Lian'er goes, and the slave family is not afraid, the slave family is also the secretary of the official!" Before Hong Tao could react, Ziju moved again, and trotted into the military tent, leaving only the reason outside.

"Shut up for me, the secretary can't get in! Wasp, take her to find Wu Si for detailed records, and go back to the family to deal with the wrong number! ”

As soon as Ziju moved, there was a small figure about to take a step, but unfortunately it was still slow, and it was given in place by Hong Tao's roar. Chen Niang also wanted to take advantage of the chaos to get in, but unfortunately it didn't work.

The first day of mixing was very unsuccessful, and after trying five or six formulas, they were extremely unstable, fast and slow. This combustion method affects the flight attitude of the rocket, which either jumps into the sky or plunges headlong into the ground.

How to solve it? No way yet. As soon as the sky is dark, there is no way to continue the experiment, and Hong Tao will not do the work of picking up the lamp in the middle of a large pile of black powder, which is not hard, but welding the detonator and sawing the bulb to death.
