Last time, I saved the lives of Yi Xiaotian and others.
It's just that at that time it was just a trial product of the airbag, and it was not ready for mass production.
But after realizing the feasibility of airbags, Yi Xiaotian returned to the north and did not delay the research——
Of course, in the process of studying airbags and various new inventions, Yi Xiaotian finally felt what it means to separate lines like mountains.
There were only inventions derived from simple physical principles, but once it came to fields such as chemical engineering, Yi Xiaozhen could only rely on vague memories and various common sense to explore.
Simpler, they are some inventions that have a long history of historical experience, such as ink making and inkstone making. Yi Xiaotian can handle it.
But just like the airbag in your hand - the principle of the airbag is not difficult to explain. It relies on the heat generated by the impact or various mechanisms to eventually form a fire source, allowing it to ignite the combustible material inside the airbag.
The dust causes it to explode and fill with strong and strong "air bags" in a short period of time.
Not to mention how difficult it is to find the material of the airbag, the flammable powder inside the airbag alone gave Yi Xiaotian a headache.
flour?
The probability of ignition is somewhat uncontrollable.
However, there is nothing wrong with using flint and steel to create sparks.
In short, after all the hardships, Yi Xiaotian finally discovered the feasibility of pulverized coal - of course there is no way to compare it with the airbags with several layers of safety mechanisms in later generations, but the characteristics of pulverized coal also make it safer to make airbags in this era.
Airbags became a viable idea.
The finer the pulverized coal, the easier it is to burn. After knowing this, it is time to try and test again and again.
Because he was worried about the danger of the experiment, Yi Xiaotian did not allow Huang Yueying to participate in this link.
For several months, he and Ma Jun risked their lives to match the fineness and quality of coal powder.
Fortunately, Huangtian paid off, and finally a relatively reliable airbag was produced.
It is also a one-time use. Yi Xiaotian chose to use cowhide to make the body of the airbag. The soaked cowhide itself has excellent toughness and is difficult to burn. Even if it does explode, it will not cause much damage.
Impact - even to a certain extent, its sound insulation effect is quite good.
The most important point is - because in the Eastern Han Dynasty, compared with the endless black technologies on Yi Xiaotian's side, it was often difficult for their opponents to master overly powerful destructive weapons.
At this moment, the huge boulder that Yi Xiaotian asked people to transport was already within the scope of common sense, and it was the biggest impact that the chariot could suffer.
So if the tank can withstand such a terrifying impact and ensure the safety of the drivers inside, Yi Xiaotian believes that the tank has achieved the ultimate in offense and defense in the field of battlefield——
——
Yi Xiaotian told Lu Su and Sun Quan what an airbag was in a simple and easy-to-understand explanation. Of course, he did not tell them about the production of airbags, although Yi Xiaotian felt that even if he told them, they would not be able to make it——
But the principle is not to reveal too much to others.
Lu Su's reaction was really surprising.
He came close to the deflated airbag, slowly stroked its outer skin with a pious expression, shook his head, and praised:
"Sir... Now that I think about it, it is indeed a very wise decision to hand over the leadership of this battle to you - I do understand why Gong Jin was so afraid of your existence back then..."
"Times create heroes... It seems that people like you, sir, are the ones who are truly favored by the times, right?"
Hearing Lu Su praise him like this, even Yi Xiaotian felt a little embarrassed.
Huang Yueying looked at Lu Su in confusion, and then at Yi Xiaotian. The longing in her eyes seemed to be one step closer.
She stayed by Yi Xiaotian's side all day long, seemingly ignoring the facts that Lu Su said - Yi Xiaotian sitting next to her at the moment, nothing could describe him better than the darling of the times.
Thinking of these, Huang Yueying felt the same kind of beating that she had when she first saw Yi Xiaotian...
"Huh? What...what happened?"
Feeling a small hand holding his clothes tightly behind his back, Yi Xiaotian turned around in confusion, but only received a hug from Huang Yueying.
Yi Xiaotian was still a little confused and could only rub Huang Yueying's little head in his arms - but Sun Quan felt uncomfortable.
He cast a resentful look at Lu Su, which seemed to be asking Lu Su: Where is the loyalty you promised to me?
But he has no intention of denying Yi Xiaotian's intention now.
Through Yi Xiaotian's words, he recalled his past experiences, and then thought of the shock caused by the impact just now - this kind of airbag is indeed somewhat powerful...
"After all that talk, why don't we put it into practice?"
"I remember you two just thought that I was bragging when I said that even inexperienced people can operate this tank. How about you just follow my command and do it now?"
"Well...then...let's try it then?"
Before Lu Su could agree excitedly, Sun Quan spoke first.
Feeling Sun Quan's change, Yi Xiaotian just smiled knowingly.
——
"Okay... Now you two, please take your positions. Yes, it's on your left side. Just put your legs into that groove-"
Listening to Yi Xiaotian's words, Sun Quan moved his body a little awkwardly and came to what seemed to be the outer armor on the left side of the chariot.
A faint light illuminated the scene in front of him, and he discovered that there was indeed a deeper groove on the seat in front of him.
Having said that, he still doesn't know how the chariot is driven... Horses? Oxen? Or is it simply people pushing the chariot?
its not right?
The doubt had already appeared. Just as Sun Quan was thinking, he also took advantage of the situation and inserted his leg into the groove.
"Huh? What is this?"
"It seems that you have felt it, General Sun? Please pay attention to your steps. There are pedals beside your feet. It would be better if you have seen a waterwheel. Please step on it as if you were stepping on a waterwheel.
On top of the pedal——"
"so?"
Lu Su seemed to have understood. He stepped on two pedals, one on the left and one on the right. Before Yi Xiaotian could continue to give instructions, he spontaneously crossed the left and right pedals and started exerting force.
A strange sound of metal collision came out - but it was not a hard impact. There seemed to be something moving inside the chariot under their buttocks. The sound was like...
"Oh? Zijing, you are really very enlightened! When I told them a few of them, they were not as quick to understand as you..."
--what's the situation.
Sun Quan was confused, but the touch on his body would not deceive him.
