If you reduce the friction of the wheels, it is easy to increase the speed, but it also means that it will be difficult to slow down, and it will be difficult to speed up, and even if the load is too large, there may be an accident when going uphill.

Liu Yi looked at the new improved rail car and shook his head, such a car is not as good as the original, the wooden friction of the wheels is still needed, what can be thought of now is to start from the power aspect, the same force should burst out of stronger speed, which is obviously against mechanics, the existence of attributes, at most, is to reduce the loss, reduce the loss of force to the minimum, not to increase the power out of thin air, can only start from other directions.

For example, it feels strange to make a sail like a boat, but obviously it doesn't work all the time, or you can consider investing more power, such as changing a two-person car to a three-person, four-person or more.

The deduction of force, Liu Yi feels that it has reached the extreme, the speed of the empty car of about forty is already the extreme, and in terms of manpower, if you want to maintain this speed all the time, you have to change frequently, after all, not everyone has Liu Yi's terrifying endurance and physical fitness.

Liu Yi has calculated that the cargo capacity of a general rail car is about ten stones when two people work at the same time, and it can travel about 20 to 30 miles in an hour.

Thirty catties for one jun, four jun and one stone, the weight of one stone is one hundred and twenty catties, but one catty in the Han Dynasty is almost first more than half a catty, if a stone is converted into a modern weight, it is about thirty-one kilograms, ten stones three hundred and ten kilograms, two people are needed to pull, and there are two replacements, such a load capacity, put it in modern times may not be worth mentioning, but in this era, it is already quite fast, and most importantly, the manpower required is not much.

Four people per capita share more than two stones, which allows the people to carry the burden, in fact, at most is the transportation volume of one and a half people, but the most important thing is the advantage of speed, even if the manpower rail car is loaded, it can only go twenty-five miles per hour, and four hours a day, it can also travel a hundred miles a day, which catches up with the marching speed of elite soldiers and horses.

What about the speed of the people's transportation? It's already good to be able to travel thirty miles a day, more than three times the transportation speed, if the empty car goes back, the speed can soar, and the logistics cost will be reduced a lot, at the moment, it has been able to make up for the population gap with Cao Wei, but Liu Yi just feels that the limitations of this rail car are a bit big, and if there is no track, it is not as practical as a trolley.

Anyway, you have to lay a place to lay the track there, and the internal logistics force is fine, but if you go out, you have to have a transport that can get off the track.

In fact, the carriage that Liu Yi made back then, modified to make a transport vehicle, the speed will not be too slow, but there is no innovation, Liu Yi himself is very concerned about this, what he wants is a new type of car that can be separated from animal power, and manpower will not be too troublesome, ordinary carriages, too simple, no challenging, can be handed over to the disciples to do, and Liu Yi now wants to do more is change and innovation, rather than just relying on the ability of the system.

"Mohou, Shamoko wants to see you!" Ma Jian walked quickly, saw Liu Yi, and bowed down.

"Then let him come." Liu Yi stopped what he was doing, and looked at Guan Xing and Zhang Bao, who were playing happily on the elephant in the distance, these two goods were not afraid of being accidentally trampled to death by the white elephant, this white elephant was larger than the ordinary elephant in Liu Yi's impression.

Soon, Shamoke saw Liu Yi under the leadership of Ma Jian and bowed down to salute Liu Yi.

"The general doesn't have to be so formal, sit." Liu Yi pointed to the stool beside him, this is not a formal occasion, there is no need to kneel and sit, and barbarian people rarely sit like this.

"Whoa." Shamoke nodded, and he was not polite, he sat down directly, and said to Liu Yi: "Mohou, the last general was ordered to investigate Meng Shu's information, and the Xizuo who was arranged in Yinye Cave recently sent the news that the lord of the Ugo country has led the Tengjia army to arrive, and it will only be able to meet Meng Huo in seven days at most." ”

"The Vine Armor Army." Liu Yi nodded, looked at Shamoke and said, "The general is also a barbarian, can there be rattan armor in the clan?" ”

"This ......" Shamoke nodded and said: "It is not easy to weave the rattan armor, but it is indeed difficult to hurt the sword after it is made, and there are some in the clan, but there are only nine pairs, which are regarded as treasures by the clan!" ”

"How is it not easy?" Liu Yi was interested and asked.

"If this rattan armor is not soaked in oil, it is not strong, ordinary swords can be easily cut, it needs to be continuously soaked in tung oil, soaked for two days first, dried after meals, it needs to be dried for at least two months, and then soaked in tung oil, so repeated five times, a pair of rattan armor usually takes two years to make, and it requires a lot of tung oil, so it is very precious." Shamoko Road.

Tung oil is a scarce material, where are there so many barbarians in general, let alone 30,000 rattan armor troops like the Ugo country, just the consumption of tung oil is an astronomical amount.

Liu Yi also wanted to try to make a pair of rattan armor by himself, but when he heard Shamoke say this, he gave up, the production cycle was too long, and the weakness was too fatal.

The problem now is, how to break these rattan armor army, 30,000 is not a small number, it is not difficult to burn the rattan armor army with a fire like Zhuge Liang in the romance, but Liu Yi is a little reluctant, although it has a fatal shortcoming, but the invulnerability is really eye-catching, and if you process it, you may be able to avoid this shortcoming.

Seeing Liu Yi frowning at Chen Si, Shamoke thought that Liu Yi was worried about how to break the enemy, and after hesitating for a moment, he said: "Mohou, in fact, this rattan armor is not unbreakable. ”

"Oh?" Liu Yi looked at Shamoke unexpectedly: "What is the general's solution?" ”

"Although this rattan armor is strong, the sword is difficult to hurt, it does not sink in water, but it also has a fatal weakness, earlier there were mountain people with more than 1,000 rattan armor army rebellion, but it was burned back by Wuling Taishou at that time, this rattan armor burned when it met the fire, and it was difficult to extinguish." Shamoke smiled bitterly: "Because of this, there are only nine pairs of rattan armor left in the last general's clan, and they haven't done much. ”

Liu Yi nodded, a little disappointed in his heart, but he didn't show it on his face, no matter what, Shamo Keken said this kind of thing, which is enough to prove that he is sincere to help himself, and said with a smile: "Thank you general, I know this matter in my heart." ”

Shamoke nodded, seeing that Liu Yi had nothing else to do, he said goodbye to Liu Yi and left.

It wasn't until Shamoke walked away that Ma Yan looked at Liu Yi and said, "Shamoke's method is indeed feasible, but why is Mohou still sullen?" ”

"This move ......" Liu Yi wanted to say that it hurt Tianhe, but in the end he didn't say it, Zhuge Liang and Zhou Yu also burned Chibi, and they didn't see anything, there are not many soldiers and horses who have died in the Han people over the years, if it really hurts Tianhe, I am afraid that the world's famous generals will have a short life, but in fact this is not the case, Liu Yi does not believe this, and said directly: "These rattan armor, if they can enter the hands of our army, if they think that they are strange soldiers, they can build miraculous effects on the battlefield of the Central Plains!" ”

In fact, the armor made by the heavenly workshop for generals at all levels can also be called invulnerability, after all, it is close to 50 defense bonuses, and some have texture bonuses and even rebound attributes, but this armor is limited to materials and workmanship, and it is impossible to popularize the whole army, and the armor worn by the soldiers is mainly leather armor or cloth armor, although there are also defense bonuses, but the effect obtained by the same number of attributes and different textures is different from 50% of 2 and 50% of 1, so can the effect be the same?

The appearance of rattan armor made Liu Yi feel that he could cultivate an invulnerable army in this regard, and it was almost invincible on the battlefield.

Of course, considering the obvious weakness, it can only be used as a surprise weapon, but the effect is equally terrifying, and it is impossible for the enemy commander to find out the weakness of the vine armor in a short period of time, so that once he strikes, the blow to the enemy will be devastating.

"This ......" Ma Jian heard this, and couldn't think of any other method other than fire attack for a while, and after pondering for a while, he looked at Liu Yi and said, "Since the blade can't work, can you try a blunt attack?" ”

"Blunt?" Liu Yi's eyes lit up.

"Mo Hou Ke still remembers the killing and wounding of the army by the Bison Formation of the Mulu King before?" Ma Jian smiled.

"I can't find so many bison in my eagerness." Liu Yi smiled bitterly when he heard this, King Mulu's family is those bison, they are basically dead on the battlefield, and now it is estimated that it has become dung, and it will take time to get it out, in fact, Liu Yi had thought about breaking the rattan armor with elephant soldiers before, but according to what King Mulu said, the elephant in the entire Ba Na Cave is just that, and it is the white elephant he sat on.

Ma Jian shook his head and smiled: "Mohou has always been quick to think, why don't you know at this time?" In the following, I just say that it is similar to the practice of the bison to break the army, not that it must be broken by the beast of the vine. ”

Liu Yi was slightly stunned, then reacted, patted his head and smiled: "If it weren't for the young reminder, I almost got into the tip of the horns." ”

There is no bison, but the power of the chariot is no worse than that of the bison, and Liu Yi did this, and the chariot he made is probably even more powerful than the bison.

Thinking of this, Liu Yi pondered: "But if you use a chariot, the terrain requirements are quite harsh. ”

Chariots are suitable for use in the plains, and it is best if you can fight high and low, and there are not many terrain suitable for chariots to gallop in this southern and central land.

Ma Yan nodded and said, "That's true, but it's not nothing, it's just that how to bring that vine armor army here will take some effort." ”

"Not bad." Liu Yi nodded and said: "In addition, there is also a brigade of partial divisions that need to cut off its foundation after Meng Shu sent troops, and I don't want to continue this battle." ”

This battle has been fought for too long, and the hearts of the barbarians have almost stabilized, and what Liu Yi needs to do next is to engage in development and infrastructure construction in this southern and central land, instead of entanglement with the remnants of Meng Huo.

Ma Jian nodded, and the two returned to the hall and began to discuss detailed countermeasures for this operation
