The color of surprise is on the face.

"Quick, try it!"

Pei Min suddenly seemed extremely anxious, and couldn't wait to confirm the thoughts in his anxious mind.

Seeing that Pei Min was so anxious, Ordas didn't ink, and introduced the entire Greek fire thrower to Pei Min, saying: "In fact, the formula of Greek fire is dead, and the real power is this instrument, its existence can give full play to the true power of Greek fire." This device is my master's latest research, and it is not as powerful as a fire-breathing boat, so it is convenient and easy to carry...... The core power of the whole device is this air pump......"

Pei Min listened to what he said endlessly, and waved his hand directly: "I understand these truths, your transmitter uses the principle of a siphon, right?" The main power comes from this manual air pump, which is similar to the bellows I am looking for, I am smelting, with the bellows as the driving force, through the hand-pulled movable wooden box, so that the leather of the bellows is filled with air, and then the air in it is pressed out to be the power. The principle of the manual air pump is the same, it also relies on the squeezing of force to eject Greek fire. ”

When he said this, Ordas was dumbfounded, and he didn't know how to interface.

I haven't eaten pork, and I haven't seen a pig run?

Although Pei Min is not a science student, he still understands the basic principles of mechanics.

Just looking at this transmitter, the principles of each are clear at a glance, but you can also see through the mystery.

Ordas swallowed his spit in horror and said, "The king of the county is also proficient in theology? ”

Pei Min shook his head and said, "I just know a little bit about it." ”

He did not seem to be very remarkable, and in this era there was no orthodox physics, and all kinds of mechanical principles were in a state of exploration.

That genius Adion was able to make such a launcher, which is already remarkable.

It is precisely because of these people that the times will continue to progress.

Ordas saw that Pei Min knew more than him, and he didn't make an axe, so he directly operated it, linking the conduit with the oil tank and the manual air pump, and then let people hold the nozzle ignition high, and violently agitated the manual air pump.

The brand-new machine, like an old-fashioned tractor, made a loud noise, abrupt and a little harsh.

When the pressure is concentrated on the air pump head, the gate is suddenly opened!

An orange-red fire dragon erupted and rushed straight out of the sky.

Pei Min couldn't help but let out a cry of surprise, in his memory, the color of fire directly represented his power.

Dark red is the weakest, followed by dark red, followed by orange, pure orange, kumquat, golden yellow, golden white, pure white, white blue, sky blue and other colors.

The smelting technology of this era was usually between kumquat and golden yellow, and the Greek fire actually spewed orange-red flames, which should not be underestimated.

Pei Min had learned about the smelting technology of this era, and had a general and conservative estimate that the maximum temperature of the flames ejected by this Greek fire should be above nine hundred degrees.

Compared to later generations, these nine hundred are nothing, but this era is already a very remarkable number.

Greek Fire is one of the most advanced technologies of this era, and it really has something unique.

Pei Min couldn't wait to come closer, looked at the copper pipe that was already slightly reddened, and asked, "This jet pipe is made of bronze?" How long does a flamethrower last? ”

Ordas was stunned, thought for a while, and said, "King Takami, about a quarter of an hour." It doesn't take that long, the flames of this Greek fire are hugely powerful. The flesh and blood body can't bear it at all, and it's not easy to extinguish. Placed on the battlefield, it can deal the most damage to the enemy in a short period of time. It's just that Greek fire is suitable for naval warfare, defensive warfare, and not for land warfare. It's okay to use it unexpectedly. When the opponent is on guard, it is useless to avoid the front. ”

Pei Minjun is so good at it, he can see the disadvantages of Greek fire at a glance.

What exactly the materials of Greek fire were mixed with him, he did not have exact data yet. But judging from the current situation, the density is still very large, and it is not easy to move.

The ejector is also made of bronze and has a certain weight.

And this thing, like black powder, is not easy to preserve.

In the process of handling, bumps and bumps, in case of spontaneous combustion and self-explosion, it is a cocoon and self-restraint.

There was no such problem in naval warfare, and the most terrible thing about Greek fire was not its heat, but its ability to float on the surface of the water, and the fire spread along the river, more powerful than any sharp weapon.

Greece is on fire, but this fire-breathing offensive is too rigid and strategically significant.

He shook his head and said, "No, you don't understand what I mean. I don't need such a lot of firepower right now, can you reduce it to less than half. I want a constant breath of fire and no mistakes. ”

Ordas didn't know what Pei Min wanted, so he pondered for a moment and said, "How much time?" The fuel of the Greek fire can be supported by the continuous spitting fire, but the heat will accumulate over time, getting higher and higher. The bronze catheter can last for half an hour at most, and it will definitely not be able to withstand more. My master once did a similar experiment, and instead of turning down the fire, he wanted to test how the bronze conduit could withstand several jets in a row. Up to five times, the bronze conduit will crack and melt. The Greek fire was so powerful that the bronze conduit had to be cooled to last for continuous use. ”

Pei Min said: "Then use steel pipes, steel is more heat-resistant than copper, what do you think?" ”

Ordas's eyes lit up and he said, "If it's good steel, you can hold on a little longer." It's just that the steel is not easy to make, especially when it is smelted into a conduit style, which is even more difficult. ”

Pei Min said excitedly: "That's in your Arabia, my Datang's smelting technology is unparalleled in the world, enough to make relative steel pipes." Not only that, but copper wires can also be tied inside and outside the steel pipe. Copper wire has the strongest thermal conductivity and can last longer. ”

Ordaz couldn't keep up with Pei Min's train of thought.

But as the deputy of the theological genius Adion, Ordas may not be as good as the master, and he also has a certain level of talent, so he recorded Pei Min's words in his heart, and planned to start studying it when he turned back.

Pei Min clapped his hands and asked the guards to take Savoy to the big tent to rest, and said to him in particular: "You have done me a great favor this time. I want you to assure you that as long as you do legitimate business, all judicial procedures will be simplified. ”

"The stewards who will be the superintendents of the army will call me a big account, and there must be no mistake!"

"You come with me!"

Pei Min asked Ordas to go to the Chinese army commander's tent with him, and acted resolutely.

Entering the big tent, Pei Min didn't pay attention to Ordas, but painted at the desk.

Drawing is not his forte, but the things he draws are simple...... Balloon!

The key to hot air balloons is power, and Greek fire and flamethrowers solve this problem perfectly......
