My Strength Does Not Allow Me to Low-key

I opened a new book "Starting from a Superstar", everyone help collect it, and give me some recommendations!

******************

The fire dragon sprayed on the ice-cold rock wall on the opposite side, and the huge temperature difference quickly caused the rock wall to make crackling noises, and then the rock wall exploded shortly afterwards, and the fine stone fragments fell off the cave wall.

Soon the person pressing the pressure pump became a little tired, and the fire dragon spewing out of the jet train gradually weakened, and then Charles Man jumped out from the side and shouted a few words, the jet train is not breathing fire.

Immediately after that, two box cars similar to a jet train were pushed up from the side, but this time the real water sprayed from this car, cold water, poured on the hot rock wall that was burned before, the huge temperature difference, Let the rock wall burst again, and a large number of broken stones fell off the cave again.

Then they rushed over to dozens of people, took the shovel and shoveled the broken stones onto the wooden cart nearby, and carried them out of the cave in carts.

The whole process seems to be very fast. Obviously these people have not known how many times they have cooperated before.

And Charles Mann also saw Xiao Feng at this time, and immediately ran from the side of the train to this side.

"Master, when did you come back?"

Charlie Sman was also very happy about Xiao Feng's return. Xiao Feng laughed and exchanged simple greetings with him, and then stared at the spray train in front of him several times.

When he was defending the city last time, he used a flamethrower, and the effect was very good. Considering the world, it happened to be rich in the kind of fierce fire oil produced after the hybridization of very local beans. Xiao Feng moved his mind and wanted to try Let's see if we can produce some flamethrowers in this world.

After all, compared with other weapons, this kind of weapon is more lethal. Whether it is defending the city or going out of the city, this flamethrower is very powerful.

In the case of not planning to equip soldiers in this world with thermal weapons, it is a very good choice to equip them with flamethrowers.

Moreover, this fierce fire oil is very unusual. It is powerful and immortal in water. Once the body is ignited, the only way to save yourself is to jump into a puddle or bury it with soil to isolate it from the air, otherwise it will only be burned to death.

Therefore, Xiao Feng felt that this was a very effective weapon that enhanced the combat effectiveness of local soldiers. It had sufficient raw materials and simple principles, so he entrusted it to Charles Mann for research.

Before he left, he probably explained the principle of the flamethrower to Charles Man. He didn't expect this old boy to tinker with it so quickly, and it seems that the effect is still very good.

Charlie Sman also gave Xiao Feng a special explanation of the spray train he had developed.

In fact, the flamethrower thing in the modern world originated in ancient Greece in the first century. At that time, the Greeks used the siphon principle to make the earliest flamethrower using hoses and pistons, and installed it on their station ship. In the naval battle with the Arabs, he gained a huge advantage.

Later, in the seventh century in the park, the Byzantines used this kind of "Greek fire" extensively during the war between the Arabs and the Arab army at that time, so as to promote the flamethrower.

In ancient China, there was also a precedent for using this kind of flamethrower, but it was much later than the Europeans. In fact, around 913 in the park, it was widely used during the wars of the North and South Dynasties.

One of the most famous battles was in the park in 919. The iron barrel flamethrower appeared in the war between Houliang and the Tang Dynasty. The principle is very simple, and it is similar to the current single-tube push water gun.

It was not until the Song Dynasty that it was widely used in city defense and water battles. At that time, the people of the Song Dynasty developed a fierce fire oil tank, which used a pedal pressurized mode to spray. At the beginning, it was quite powerful.

However, it was discovered that the shortcomings were later, because the air tightness was not strong enough, the pressure was not strong, and the farthest jet could only be five or six meters, so in the subsequent war, it was abandoned.

And the jet train invented by Charles Mann in front of him, because of the unique natural conditions of the world, is much more powerful than the flamethrower developed in ancient times by Xiao Feng.

In Xiao Feng's world, the flamethrower invented in ancient times faced an important problem, that is, the lack of sealing, resulting in insufficient pressure that the pressure pump can provide, so the fire is not far away.

Even if the flamethrower used by the Byzantines is more advanced, it is only a dozen or twenty meters away.

In this case, it was only after the arrival of later rubber products and the emergence of a large number of machining processes that the pressure pump and the sealing problems of the cupping tank were solved, which allowed the effective range of the flamethrower to be greatly improved.

But even so, the farthest spray distance of modern soldiers' individual flamethrowers is only 100 meters.

Charlie Sman used the natural gum produced by a tree in this world to solve the sealing problem, and even made a hose with a tenacious rattan, so that the range of the jet train he made would be long. Compared with the flamethrower made in the ancient world by Xiao Feng, the spraying distance is much longer.

Because there are some problems in the pressure pump that have not been solved yet, the spraying distance is not too far, but it can reach 34 meters. This result can be said to have surprised Xiao Feng very much.

In this era and current technology, it is impossible to miniaturize the jet train and make it individual. But as long as the range of the jet train is increased, the effect will be the same.

If the firing range can reach 100 meters, then Xiao Feng can boldly take the human soldiers out of the city and fight the half-orcs.

Even if half-orcs do not lose their strength, even if their archers are tough, their bows and arrows can only have a range of one hundred to one hundred and fifty meters.

If the spray train can reach a range of one hundred meters, and then equip him with a batch of iron can operators, Xiao Feng will be able to perform live barbecues for those half-orcs.

Imagine the scene of a hundred jet trains rushing to the front of the half-orcs and violently spitting fire. That is a tight firepower cordon. No half-orcs should even rush to the front of the human soldiers.

However, the problem of this range cannot be solved in a short while. It also requires Charles Mann to study the pressure pump to solve the problem of increasing pressure.

Xiao Feng also gave some solutions, such as whether the hand pump can be changed to a foot pressure pump, so that the power output of the person can be greater, and on the circulation machine of the pressure pump, can some pulleys be used to reduce The output of human power.

After all, in an era when there is no hydraulic pump, if you want to solve the pressure problem, you can only use your brain in mechanical design.

Charles Mann’s suggestions to Xiao Feng have been recorded one by one. Great Master Master, every sentence can inspire him, if it weren’t for Master Master’s earlier points, how could he make it? The jet train that appeared in it?

Even though the current spray trains still have many defects, Xiao Feng is already very satisfied with these spray trains. Although they still don't meet the standards for going out of the city, they are still qualified to defend the city.

With a spraying distance of 34 meters, next time a half-orc wants to climb a wall, they will be grilled into skewers by these spraying trains.

"You spray train is very good, I think it will be called the fierce oil tank from now on!"

"Master Xie for giving the name!"

Of course, Xiao Feng prefers to name the jet train after the ancient Chinese name, which means the spread of civilization, and Charles Mann will not refuse Master Master’s name for his invention. If he can rely on the fierce oil tank in the future Defeat the Orcs, it will mean that he has a chance to stay in history!

Coming out of the cave, Kaila took Xiao Feng to the right hand side of the castle. There were several factories over there. Two of them were the distribution of the blacksmith shops that the dwarves came to open, and the other was a cement and concrete factory.

These are not the focus of Xiao Feng's attention. The third perfume specially held by the fox spirit Yuzao Xiu, and the Yurongye manufacturing workshop is the focus of his inspection this time.

Because this fox spirit was smoky and charming, his skill in seduce men was really great. When Kayla came here to build a new city this time, she was really worried about leaving her at the base, so she brought her by her side.

She also knows that Xiao Feng attaches great importance to the Yurong Liquid and perfume that this fox can produce~www.ltnovel.com~ So she opened a workshop here specifically for her, and also arranged a dozen men for her. Responsible for helping her collect all kinds of raw materials needed to make perfume and jade liquid.

Moreover, the female assistants who arranged for her were regarded as defensively against this fox.

Of course this vixen knew why Kayla was so guarding against her. If someone else treated her this way, he might have exploded long ago with the orc's natural rebellious temper.

But Kayla's status in this human tribe is not ordinary, he is still the lover of the human archmage, so this vixen doesn't dare to make mistakes, and can only obediently submit.

Xiao Feng's arrival also made her very pleasantly surprised. She also presented her treasures and took out the recently produced Yurong Liquid and perfume to give Xiao Feng a gift.

Xiao Feng took a look at it, and the output was really a lot. The Yurongye, just a 50 kg wooden barrel, contained two barrels, a full 100 kg.

The perfume is a little bit more than this. It is packed in four big barrels. During this time, so much can be produced. Xiao Feng is very happy. He also praised and encouraged this vixen. By the way, he has rewarded her a lot. Drinks and sweets.

These things are all ordinary things in the modern world, but here, that is the top delicacy. The vixen is also very happy to receive such a reward, which means Xiao Feng's recognition of her.

Even Kayla was jealous when he saw so many ‘good things’ that Xiao Feng had assigned to the fox, and before Xiao Feng was talking to the fox, she took Xiao Feng and left the workshop.

That night, of course, it was indispensable and lingering.

The next morning we only went to bed, and Xiao Feng received a letter from the homing pigeon at the castle in the north. The content was very simple: the half-orcs are here again!
