Jian Mingyue broke Qin Shaofeng's whereabouts, and Qin Shaofeng had no choice but to walk in from outside the door in a sneer, and said with a smile: "Miss Jane, I'm sorry, I didn't mean to eavesdrop, I was really too interested in your conversation, I couldn't help it, hehe!" ”

Then without waiting for Jian Mingyue to say anything, he hurriedly pulled the honest-looking soldier behind him over and said, "Miss Jian, it's a coincidence, when I went to find someone, they recommended this brother to me. Pen? Interesting? Pavilion wWw. ｂiquge。 infoBefore he joined the army, his family was specialized in making fireworks, and after joining the army, he also specialized in playing explosives, and he definitely didn't say anything about his skills! By the way, brother, what's your name? ”

The honest soldier stood up and said: "Back to the sir, my name is Zhang Dazhuo, and everyone is called me Shuzi." ”

Jian Mingyue said: "Bolt, we want to make a big drill monkey, we need your help." This is a rough drawing, can you see if it will work? ”

Zhang Dazhuan looked at the drawings for a long time before scratching his head and said, "That...... I don't understand ......."

Qin Shaofeng angrily gave him a brain jump: "I don't understand, you still watch it for a long time?" Aren't you the best Demoman? Can't understand something so simple? ”

Zhang Dazhuan rubbed the beaten place aggrievedly and said: "I never used drawings when I blasted, and no one told me to use drawings!" ”

Or Tan Yuxing often comes into contact with folk masters who are similar to Zhang Dazhuan, who obviously have goods in his stomach but can't pour them out, so he simply dragged him to Master You and directly explained it with a half-finished product comparison. Zhang Dazhuan nodded and said, "Oh, that's the case." It's a good idea to divide the big bucket into seven or eight smaller buckets, and you can use cast iron to make the bucket heavier, so that it can be more stable when the gunpowder erupts. It's just that there are still too many of these iron buckets, and if they erupt together, your head won't be able to hold up at all, and it will definitely be crushed. It's best to divide these seven or eight iron buckets into two parts, and then light the rest of the ...... after the first part is sprayed."

Most of the technicians are like this, usually they behave very woodenly, but when it comes to their own specialty, they immediately become talkative. Zhang Dazhuan also participated in the design of the underwater thruster, and the discussion with Master You and Tan Yuxing was in full swing.

Jian Mingyue's thoughts were poured out, and there was no way to interject on what to do, so she could only visit this workshop. Then I found out that Master You's movements were very fast, and a fat rocket-like thing had already had a rough prototype. And the reason why Master You can do it so quickly is because when Tan Yuxing was designing, the materials he used were all available here. For example, steel bars, iron buckets, levels, etc., can be used when you take them.

Qin Shaofeng also came forward, tested the strength of the steel bar with his hands, and grinned: "Miss Jane, can this thing really work?" If something goes wrong, you're in danger! Even if it works, I'm afraid it's hard to manipulate, right? Jumping out of the water or plunging into the bottom of the river is nothing, but if you hit a reef or a warship, then ...... Let's think of something else. ”

Jian Mingyue nodded and said, "Looking at this thing, my heart is also beating." If there was another way, I wouldn't use it. Do you have any other way? Let's talk about it. ”

Qin Shaofeng scratched his head and said, "Perhaps, just use the electric propeller to make a simple thruster." It's slower, but it's safer. Anyway, the warships of the devils are cruising in the river repeatedly, and they can always find opportunities when they wait on their routes. ”

Jian Mingyue shook her head and said, "No, that's too inefficient." In that case, as long as one warship is blown up, the other devils will be alert, and there will be no chance to blow up a second ship. Even if the devil finds my location, I can't escape with a cannonball. ”

Qin Shaofeng sighed and said, "Yes, the speed is fast, and you can escape quickly." Just this thing, alas! ”

Jian Mingyue didn't care too much, anyway, her physical fitness was good enough, and she could drink the red bottle to recover no matter how many injuries she had, so she had enough confidence. He then inspired Qin Shaofeng and said: "Hey, you said, if this thing is not used underwater, but directly flies into the sky like a real Drill Monkey, and it is filled with explosives, what will it look like?" ”

The fat rocket that Tan Yuxing and the others made, since it can hold one person, can hold nearly two hundred catties if it is replaced with explosives. How powerful is 200 pounds of explosives once they explode? It is estimated that it can top a giant cannon of more than 300 millimeters, right? Now that the national army is attacking Shanghai, the most troublesome thing is that in addition to the warships on the river, the fortress of the devils is too strong. If there is a powerful cannon, what fortress are you afraid of? So after understanding what Jian Mingyue meant, Qin Shaofeng's eyes lit up all of a sudden, even brighter than a searchlight!

Qin Shaofeng pondered it again, the more he thought about it, the more feasible he felt, he couldn't help laughing excitedly, he didn't care about the identity of Jian Mingyue Immortal, hugged her and said, "Thank you!" Thank you so much! One of your ideas, I don't know how many brothers' lives have been going on for a long time! I want to thank you for them! ”

Saying that, Qin Shaofeng let go of Jian Mingyue, and actually knelt on the ground and kowtowed a few times.

When she was just hugged by Qin Shaofeng, Jian Mingyue was stunned all of a sudden, and when she realized that her anger soared and she wanted to teach him a cruel lesson, this guy let go of her in time, and knelt down and kowtowed, making Jian Mingyue unable to make a move. This made her hold her stomach full of breath and couldn't come out, so she could only yell viciously: "Get out!" Get out of here! ”

Qin Shaofeng didn't care, he smiled, got up and ran. When he ran outside the factory gate, he suddenly changed his face, let out a sigh of nervousness, pressed his chest and waited for the beating heart to slow down, and then he happily said to himself: "Pick up a life." ”

He really didn't mean it just now, he subconsciously hugged Jian Mingyue out of excitement. But then he reacted, and in a hurry, he thought of a way that was not a solution, and used gratitude as an excuse to kneel down and kowtow, which really made Jian Mingyue difficult to do. Although he escaped, Qin Shaofeng also understood that he had left a very bad impression in Jian Mingyue's mind, and he was afraid that he would not give himself a good face in the future. But it's worth it, as long as you make that kind of big killing weapon, you will be the number one hero in conquering Shanghai, and it will not be a problem to increase the official and become a knight in the future.

Qin Shaofeng, who had regained his smile, ran away, while Jian Mingyue continued to wait here. A little more than an hour later, the first jet underwater propulsion was born. And after discussion and modification by three people, this thruster is a little different from the original.

The first is the iron barrels in the tail, which are not ignited together, but each iron barrel has a lead, which is attached to the lever of the rudder, and it is up to the operator to choose whether to ignite one or several, erupt one after the other or all together.

The second is the first part of the glass, which has not changed in five layers, but the glass is filled with fine fish glue and very fine iron wire is mixed into it. In this way, although the transparency is reduced a lot, the strength is also increased a lot, at least once the glass is broken, it will stick together and will not hurt the people inside.

Now that she has the finished product, Jian Mingyue can't wait to experiment with it. So together with Tan Yuxing, Master You, and Zhang Dazhuan, they came to a deserted riverside and put the thruster down. Jian Mingyue herself put on the diving suit and oxygen tank that Qin Shaofeng had just sent, and got into the space like an iron cage.

This thruster was either iron or glass, and it was so heavy that it sank as soon as it entered the water. Jian Mingyue was not in a hurry, and only after sinking to the bottom did she adjust her position, use a level to measure whether the thruster was flat, and then tear off a thin rope tied to the rudder. As soon as the string was pulled, the gunpowder of a small iron bucket was immediately ignited, and the flames broke through the exit of the wax seal, creating a large number of bubbles.

However, Jian Mingyue overestimated the power brought by the fire-powder eruption, and a small iron bucket ignited, but it couldn't be pushed at all, and the thruster was still in place. When Jian Mingyue saw this situation, she simply ripped off half of the string and lit the gunpowder of the three small iron buckets. This time the thrusters finally moved, but they were still slow, not much better than a snail crawling. This made Jian Mingyue impatient, and simply ripped off all the strings and set all the iron buckets on fire. In this way, the speed finally increased, and it rushed out all at once.

Using fire-powder jet as power, it is really difficult to control. Either you can't push it, but once you do, it's scary fast. The most terrible thing is that the speed is getting faster and faster, so that Jian Mingyue nervously held the rudder and did not dare to relax for a moment. But there was nothing wrong with herself, but there was a problem with the goggles on her eyes, and she was moved by the violent current, just blocking her vision.

Once you can't see something, it's hard to grasp the direction. Jian Mingyue had no choice but to let the thruster rush up to the water. However, in mid-air, the resistance of the water disappeared, the power of the thrusters was excessive, and the rudder was not easy to use, and the entire thrusters began to roll in the air, making Jian Mingyue dizzy. Fortunately, she still fell into the river in the end, and if she fell on land, I am afraid that her journey to this copy will be over.

If you don't succeed once, try it a second time. This time, Jian Mingyue fixed the goggles well, and finally there was no problem with them, but the thruster was still shaking violently because of the speed, and finally it was as if it had hit something, and the whole thing was folded at right angles.

During the third experiment, the structural strength of the thruster was reinforced, but severe shaking still occurred. In this kind of shaking, Jian Mingyue couldn't control the direction at all, and as a result, she plunged headlong into the silt at the bottom of the river.

In the end, Tan Yuxing could only set all the small iron barrels filled with gunpowder to the state of composition, and once the speed was fast enough to shake the thruster, he would throw away a reduction in speed. But it is a dilemma to reduce the speed and not be able to catch up with the warship.

Just as Tan Yuxing was revising and modifying, time passed slowly. When they came to the riverside again to experiment, they heard a violent explosion on the river in the distance. Jian Mingyue was startled and hurriedly climbed to the top of a big tree to look at it from afar, but it didn't matter what she saw, and she kicked and broke the branch that was already struggling to support her. It turned out that it was the national army that was firing crude rockets to attack warships on the river!
