"The supervising army, the division commander, the Qing army and the foreigners have retreated!" A soldier who had gone out to visit hurried back to report.

"Count them as fast as they run!" Hong Xuanjiao snorted lightly, turned her head and asked, "Wang Feng, the city wall has been blasted into a big gap, do you want to repair it a little?" Otherwise, the Qing army would attack at night, and I was afraid that it would be difficult to deal with. ”

"No!" Wang Feng waved his hand without thinking: "We spent a lot of effort to repair it, wouldn't it be in vain for foreigners to bombard the gunboat?" In fact, today is lucky, if the foreigners secretly fire the cannon at night, I am afraid that you and I and many soldiers will die without a place to bury, in front of the cannon, the city wall has lost its defensive purpose, so be it, strengthen the vigilance, and at the same time do a good job of pacifying the people in the city. ”

"Hmm~~" Hong Xuanjiao was also apprehensive when she thought about it, nodded and said, "I'll arrange for the sisters to do it immediately." ”

Maybe Hong Xuanjiao didn't realize it herself, she had gradually developed the habit of asking Wang Feng for instructions, Wang Feng didn't remind her, and smiled slightly: "Sister Xuanjiao, turn your head around." ”

"Huh?" Hong Xuanjiao subconsciously turned her head.

Wang Feng pulled out a small straw from the tip of her hair, patted the dust on her shoulders and back for her, and then shook her head and said: "Sister Xuanjiao, a woman's beauty is a gift from God, you must cherish it very much, you can't be sloppy, do you think that if you are fascinated by me, you don't have to take care of the image?" I'll send you a little mirror another day. ”

Suddenly, Hong Xuanjiao was embarrassed and annoyed, and glared at Wang Feng fiercely, but there was a trace of sweetness in her heart, although Xiao Chaogui was the king of the south, she was also Xiao Wangniang, but she had never experienced the taste of flirting and scolding in Xiao Chaogui, usually the husband and wife were busy pretending to be ghosts, and they had to deal with the continuous encirclement and suppression of the Qing army, how could they have the heart to cultivate the relationship between husband and wife? After Yong'an was crowned king, Xiao Chaogui followed the trend, and in a blink of an eye, he got more than a dozen concubines, which made Hong Xuanjiao's indifferent husband and wife love for Xiao Chaogui completely dissipate without a trace!

Although Wang Feng's feelings are also a mess, they are far less than the absurdity of the kings of the Taiping Heavenly Kingdom, at least they pay attention to affection, especially the caring words and small actions that are not taken lightly, which makes Hong Xuanjiao's heart gradually sink and become more and more difficult to dial himself!

Wang Feng looked at Lu Dayou, who wanted to laugh but didn't dare to laugh, and his face was flushed, so he said: "You find some brothers to clean up the ruins, clean up the corpses and bury them, and then take a few people to find a nearby pond and get two small boats to come over." ”

"Yes!" Lu Dayou walked away quickly.

Hong Xuanjiao recovered from her shame and hurriedly asked, "Wang Feng, what are you going to do?" ”

Today's Hong Xuanjiao is full of interest in Wang Feng's endless inventions, as long as Wang Feng has a little strange behavior, she will reflexively expand her curiosity.

Sure enough, Wang Feng snorted coldly: "Mine!" The threat of the Hermes is too great, we must find a way to blow it up, and at the same time take this opportunity to warn the Western powers, although we do not have strong ships and artillery, but the Yangtze River is not their own inland river, if you want to come in, let Lao Tzu weigh it first, whether there is a life to go out! ”

"Oh? Then I'll have to go and see, you wait for me later! Hong Xuanjiao hurriedly went to explain to the female soldiers and went to the city to appease the people.

After a few minutes, Hong Xuanjiao hurried back, and after a while, Lu Dayou sent someone to say that he had found a pond outside the city, and Wang Feng immediately asked people to fetch some mines to join them, and he and Hong Xuanjiao rode away.

This is a small pond with an area of only a few hundred square meters, two fishing boats are parked on the shore, Wang Feng will modify the mine on the spot, if it is correct, it will be used to blow up and sink the Hermes!

There were many soldiers around the pond, their faces full of anticipation, they were both envious and hateful of the Hermes, and their feelings were very complicated!

In modern society, there are various ways to trigger mines, and it is impossible to prevent them, and at that time, Wang Feng could only do one kind of mine, that is, floating mechanical impact mines, the key point is the contact fuze, there are three kinds of contact fuzes, limited by time and materials, Wang Feng started to inertial collision fuzes.

Wang Feng asked the blacksmith to temporarily cast iron balls, iron rings, liners, iron springs, pressure rods and other components, its working principle is, in the standby state, the spring through the guò pressure rod will transmit the pressure to the metal ball, so that it is stationary in the center of the metal liner, when the mine body is collided by the ship, the closure with the mine body to obtain inertial acceleration, so that the metal ball and the metal lining plate relative displacement, if the acceleration and displacement are large enough, the metal ball will be in contact with the metal ring, so that the circuit is turned on to detonate the mine, due to mechanical reasons, Such a fuze cannot increase sensitivity while maintaining safety, and can only be weighed between the two.

Also limited by time and realistic conditions, Wang Feng could not make a circuit in a short time, he could only follow the detonation principle of the grenade, when the metal ball and the metal ring touched, pull the fuse, and detonate the thunder~~ tube through guò friction, and then detonate the mine.

As for making the mine float, it's very simple, put the mine in a closed wooden box, just leave the trigger fuse outside.

After two hours, the first mine was formed, and because he was worried that the fuse would not touch the hull, Wang Feng arranged the fuses on all sides.

"Stand far away, it's better to lie down!" Wang Feng turned his head and drank, everyone looked at each other and slowly retreated, but there was no one lying down.

Seeing that everyone was out of a safe distance one after another, Wang Feng didn't pay attention to it, lightly put the mine into the water, and slowly moved it to the center of the pond with the oar.

"Boom!" With a loud bang, the mine exploded, stirring up a column of water a foot high, accompanied by the flying of wood planks and iron sheets, which frightened everyone and made some people fall down unconsciously!

This also includes Hong Xuanjiao, with a disgraced face, and said dissatisfiedly: "Wang Feng, what kind of nerves do you have?" ”

Wang Feng said lightly: "The waves in the river are surging, but they are not calmer than a small pond, well, a wave can be blown up, which means that the ability to resist wind and waves needs to be improved, come, Lu Dayou, you all come here, the next adjustment is handed over to you, the key point is to master the balance." ”

"Oh!" Lu Dayou and others carefully modified the mine according to Wang Feng's requirements, and throughout the afternoon, the rumbling explosions around the pond continued, Wang Feng was not in a hurry, holding the Minny gun to adjust the scale crosshair, and in the crackling gun, finally smashed a wine jar placed 500 meters away, which announced that the Minny gun could be officially installed.

"Master Shuai, look, this one will definitely work!" As soon as Wang Feng recorded the parameters, Lu Dayou waved his arms and shouted.

Wang Feng ran over to take a look, a mine was floating in the water, Lu Dayou took the oar, kept hitting the water, and swung the mine towards the fishing boat located in the center of the pond.

Three feet!

Two feet!

One foot!

Everyone's eyes froze, this was the first mine to resist the waves, the moment it touched the ship, boom, the ship disintegrated in the dazzling firelight, the debris splashed into the air, and smashed into the water like dumplings!
