Chapter 68 Zhao Si's Explosive Cavalry Tactics

Wang Li wanted to speak, but he just thought of the other party's lonely situation, so he didn't say anything more in the end, instead, he continued to try the three-piece suit with great interest.

Wang Li's equestrian skills are good, and with the three-piece suit on the horse, a skilled knight like him can completely free his hands on the back of the horse.

It also means that fighting on horseback, drawing a bow and setting an arrow, is more relaxed and freehand.

And Zhao Si was studying the reclining chairs and wheelchairs sent by the craftsmen.

Needless to say, the reclining chair is mainly a design idea without too much technical content. When I go up to it, it is rickety and very comfortable.

"Zhao Bugeng, try a wheelchair!" The military craftsman rubbed his hands beside him and smiled.

Zhao Si sat up on the other side's earnest expression, and the craftsman pushed it. Zhao Si was surprised to find that when passing through uneven places, the feeling of bumps was not obvious.

"How do you do this?" Zhao Si got up and squatted down in surprise, but he didn't see anything like a spring.

The craftsman finally showed his complacent expression for the first time in front of Zhao Si.

"here!"

The craftsman smiled and pointed to the structural position of the wheelchair wheel support shaft.

Zhao Si was surprised to find that there were actually thick and thin bamboo tubes, and when he was trying to put pressure on the wheelchair, he found that the matching bamboo tubes would float up and down with the pressure.

"Here is the mechanism? What did you use?" Zhao Si asked in surprise.

"Bamboo board!" The craftsman replied.

After that, the craftsman skillfully dismantled the wheelchair and took out the supporting shafts of the four wheels.

Two bamboo tubes of different thicknesses are interlocked with each other. After being disassembled, there are four bamboo boards inside.

Zhao Si observed carefully and discovered the ingenuity in it.

The small bamboo tube inside has holes on all sides, and a wooden core is fixed in the middle. The bamboo boards are fixed up and down on the wooden core. As pressure is applied, the bamboo boards will bend outwards to provide elasticity.

Four axles are exactly four shock absorbers.

Bamboo sheets act as springs.

Of course, the shock absorption range is very limited, at most two fingers, two bamboo tubes, big and small, are in real contact.

"So that's how it is!" Zhao Si also went to school, and immediately discovered the reason after taking it apart.

"Use the elasticity of bamboo to reduce bumps, and the bamboo tubes are nested together to provide buffer space for up and down movements." Zhao Si marveled.

This thing is not too difficult to say, but this is the pre-Qin era.

"Zhao Bugeng understands now?" The craftsman's face was full of surprise, and he was also a little depressed when he was interrupted if he couldn't pretend.

Zhao Si's hands-on ability is indeed not strong, but his "invention" ability is strong!

After Zhao Si came to Lantian Camp, not to mention Wang Li, the craftsmen were shocked every now and then.

Although Zhao Si's hands-on ability is not good, he talks one after another, including Zhao Si's exclusive calculation method, which has become popular among craftsmen.

The shortcomings of Arabic numerals are obvious, but the advantages are also very obvious. As long as you are familiar with modern calculation formulas, the calculation efficiency will be improved by more than a little bit, and the craftsmen happen to use them. knowledge.

Craftsmen have a good impression of Zhao Si, mainly in this era when knowledge is directly equivalent to wealth, Zhao Si selflessly taught them, and made many practical gadgets for them, and taught them modern composition methods, modern mathematics and application The formula is no different from that of the boy who scattered money.

The most important thing is that Zhao Si has no arrogance yet, and Zhao Si can understand the knowledge mastered by craftsmen. It is really hard for them not to love Zhao Si like this.

"It's a pity that the bamboo boards are too poor to withstand. I'm afraid they have to be replaced every now and then when used on wheelchairs. They can't be used on chariots!" the craftsman said a little disappointed.

"Then how about using something stronger?" Zhao Si asked with a smile.

"Like gold!"

"How is it possible? Gold is easy to break and hard. Either it cannot provide elasticity, or it will break." The craftsman shook his head.

"How about another shape?" Zhao Si drew the shape of a spring on the ground again.

"Is this easy to break?"

The craftsman was lost in thought while looking at the shape of the spring on the ground.

After a long silence, the craftsman said: "I'll try! I'll try! Maybe it's true!"

Having said that, the craftsman quickly bowed and left, not in the mood to show Zhao Si the rest of the wheelchair's functions and left in a hurry. Zhao Si looked at the back of the craftsman leaving and shook his head with a smile.

Surely it won't work.

At least with the smelting technology of this era, it's really not enough.

Even if it is really rubbed out by hand, mass production is still a big problem.

The elasticity of brass is terribly poor, and there is a limit to how good bronze is.

Steel has the best modulus of elasticity, but the iron smelted by the primitive iron-smelting technology of this era is extremely brittle, and its elasticity may not be as good as that of bronze.

The ultimate possibility is that the craftsman has worked hard to create a spring that cannot be mass-produced and has low practicability.

However, this is still very meaningful, at least this is a great progress from theory to practice, and it will point the way forward for future generations.

On the other side, Wang Li ran for a long time, got off his horse and walked towards Zhao Si with joy on his face.

"This is a deck chair? Let me try it!" Wang Li unceremoniously squeezed up and pushed Zhao Si out with his butt.

The reclining chair swayed back and forth, Wang Li almost lost his balance and fell, Zhao Si got up helplessly and sat on the wheelchair.

There are no stools these days, and sitting on knees is really, really uncomfortable, but there is no way, etiquette and customs are not so easy to change.

"I can't see the clues of the horseshoe for a while. I will let the soldiers lead the horses to walk back and forth overnight, and then I will know the benefits. This horse saddle is really a wonderful thing!"

"I can draw a bow and set an arrow while galloping a horse!" Wang Li said with excitement on his face.

"Ah? Isn't that true for all barbarians in the grassland?" Zhao Si was taken aback for a moment.

Wang Li looked at Zhao Si with a strange expression and asked, "Where did you hear this? If all the hussies in the grassland are like this, how can there be Yan, Zhao, and Qin?"

"It is the most skilled rider. When he gets on the horseback and gallops, he can't use all his strength. He draws the bow and sets the arrow. First, he must slow down his riding speed, and second, he must maintain his body. Shooting arrows hastily, one or twenty steps There may not be any, and arrows may not run faster than horses." Wang Li explained to Zhao Si seriously.

"Could it be that the Hu people first rode their horses to reach the range of their bows and arrows, then stopped to shoot arrows, and then rode their horses to cover a distance, and so on and on?" Zhao Si discovered Hua Dian, but it was so funny no matter how he thought about it.

The main thing is that Zhao Si really doesn't know about cavalry warfare. His understanding of Hu people's tactics is limited to the classic kite-flying style in online novels, archery at a distance, and he is running when you catch up.

Then shoot and run again, jumping back and forth.

Zhao Si really thought that all Hu people fought like this.

"Where did you hear that?" Wang Li looked at Zhao Si with a strange expression.

This kind of tactic cannot be said to be invincible in the world, it can only be said to be broken at the first touch.

The kite-flying style that Zhao Si talked about was quite explosive throughout the Spring and Autumn and Warring States Periods.
