If the friction of the wheel is reduced, it is easy to lift the speed, but it also means that it will be difficult to slow down and speeding up will be difficult. Even if the load is too high, something may happen during the uphill.

Liu Yi looked at the new improved rail car and shook his head. Such a car was not as good as the original one. The wooden friction of the wheels was still needed. What can be thought of now is to start from the power aspect. The same force must burst out with a stronger speed. This is obviously a violation of mechanics. The existence of attributes can at most reduce losses and minimize the loss of force, rather than in turn increasing strength out of thin air. You can only start from other directions.

For example, it is like a sail like a boat, but it is obviously not available at all times. It feels strange, or you can consider increasing your investment in strength, such as changing the car to three, four or more.

By deducing power, Liu Yi felt that he had reached the extreme. The speed of an empty car at about 40 was already the ultimate. Moreover, in terms of manpower, if you want to maintain this speed forever, you have to change frequently. After all, not everyone has the terrifying endurance and physical fitness of Liu Yi.

Liu Yi calculated that when two people work at the same time, the load capacity of a rail car is about ten stones, and it can travel about twenty to thirty miles in one hour.

Thirty kilograms are one jin, four jin and one stone, and the weight of one stone is 120 kilograms. However, in the Han Dynasty, one kilogram was about half a kilogram first. If one stone was converted into the weight of modern times, it would be about 31 kilograms and ten kilograms of ten stones, which would require two people to pull it. There are two replacements. Such a load capacity may not be worth mentioning in modern times, but in this era, it would be quite fast. The most important thing is that the manpower is not needed.

The four people allocated more than two stones per person. If the civil servants carried the load, it would be the most transported by a half civil servant. But the most important thing is the advantage of speed. Even if the human rail car is loaded and carried, it can only travel twenty-five miles per hour. If it travels four hours a day, it can travel a hundred miles a day, which is as fast as the marching speed of elite troops.

What about the transportation speed of civilians? It is good to travel thirty miles a day. If the transportation speed is more than three times, the speed of empty cars can soar, and the logistics cost will be reduced a lot. At present, it can make up for the population gap with Cao Wei. However, Liu Yi just feels that the limitations of this rail car are somewhat large. If there is no track, it is not as practical as a trolley.

Anyway, you have to build a place to lay the tracks there. There is no problem with internal logistics, but if you go out, you still have to have transportation tools that can leave the track.

In fact, the carriage that Liu Yi made back then would not be too slow to be modified into a transport car, but it did not have innovation. Liu Yi himself cared about this very much. What he wanted was a new car that could be free from animal power and human power. For ordinary carriages, it was too simple and not challenging, and could be left to the disciples to do. Liu Yi now wanted to change and innovate more, rather than relying on the ability of the system.

"Mr. Mo, Shamoke wants to see you!" Ma Su walked over quickly, saw Liu Yi, and bowed.

"Then let him do it." Liu Yi stopped the work and looked at Guan Xing and Zhang Bao, who were having fun playing on the elephant in the distance. These two guys were not afraid of being accidentally stepped on to death by the white elephant. This white elephant was even larger than the ordinary elephant that Liu Yi thought.

Soon, Shamoke, under the leadership of Ma Su, saw Liu Yi and bowed to Liu Yi.

"General, don't have to sit so politely." Liu Yi pointed to the stool beside him. This is not a formal occasion, there is no need to kneel down, and barbarians rarely sit like this.

"Here." Shamoke nodded, without any politeness, sat down and said to Liu Yi: "Mr. Mo, the general was ordered to investigate Meng Huo's information. Recently, the detailed work arranged in Yinye Cave has sent news. The king of the Ugo Kingdom has already led the Fuji Armor Army and will be able to meet with Meng Huo in only seven days at most."

"The army of vine armor." Liu Yi nodded and looked at Shamoke and said, "The general is also a barbarian. Is there any vine armor in his clan?"

"This..." Shamoko nodded and said, "It is not easy to build a vine armor, but it is indeed difficult to hurt swords after it is made. There are some in the clan, but there are only nine mates, and they are regarded as treasures by the clan!"

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

"If this vine armor is not soaked in oil, it is not strong. Ordinary swords can easily break. They need to be soaked in tung oil continuously. They are soaked for two days first, dried after a meal, and then dried for at least two months, and then soaked in tung oil. This is repeated five times. A pair of vine armor usually takes two years to make, and requires a lot of tung oil, so it is very precious." Samoke said.

Tung oil is a scarce material. There are not so many barbarians in general, let alone the 30,000 vine armor troops like the Ugo Kingdom. The tung oil consumed is an astronomical figure.

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

The problem now is that 30,000 is not a small number of these vine armored troops. Just like Zhuge Liang in the Romance of the Romance, it is not difficult to burn the vine armored troops with fire, but Liu Yi is a little reluctant. Although it has fatal shortcomings, its incompetence is really enviable. After processing, it may be able to avoid this shortcoming.

Seeing Liu Yi frowning Chen Si, Shamoke thought Liu Yi was worried about how to defeat the enemy. After hesitating for a moment, he said, "Mr. Mo, in fact, this vine armor is not unbreakable."

"Oh?" Liu Yi looked at Shamoko unexpectedly: "What are the solutions for the general?"

"Although this vine armor is strong, and it is difficult to hurt the sword and does not sink when encountering water, it also has fatal weaknesses. Earlier, the people of the mountain rebelled with more than a thousand vine armor troops, but it was burned away by the prefect of Wuling at that time. The vine armor burned when encountering fire and was difficult to extinguish." Shamoko smiled bitterly and said, "For this reason, only nine pairs of vine armor were left in the last general clan, and they did not do more."

Liu Yi nodded, feeling a little disappointed, but it was not shown on his face. No matter what, Shamokköken said this, which was enough to prove that he was sincerely helping him. He smiled and said, "Thank you, General, I know this."

Shamoke nodded, and saw that Liu Yi had nothing to do, so he said goodbye to Liu Yi and leave.

It was not until Shamoke walked away that Ma Su looked at Liu Yi and said, "Shamoke's method is indeed feasible, but why is Mo Hou still depressed?"

"This move..." Liu Yi wanted to say that it would hurt Tianhe, but in the end he didn't say that Zhuge Liang and Zhou Yu were still burning the Red Cliff, but they didn't see anything. I don't know how many soldiers and horses died in the Han people's internal struggles over the years. If it really hurts Tianhe, the famous generals in the world might have short lives. However, in fact, it was not the case. Liu Yi didn't believe this and said directly: "If these vine armors can be in the hands of our army, they think that the surprise soldiers will be able to achieve amazing results on the battlefield in the Central Plains in the future!"

In fact, the armor made by Tiangongfang for generals at all levels can also be called invulnerable swords and guns. After all, the defense bonus of nearly 50 is also texture bonus and even rebound attributes. However, this kind of armor is limited to materials and workmanship, and it is impossible to popularize the entire army. The armor worn by the soldiers is mainly leather armor or cloth armor. Although there are also defense bonuses, the effects obtained by the same number of attributes and different textures are 2% of 50% of 1% of 50%. Can the effect be the same?

The appearance of the vine armor made Liu Yi feel that he could cultivate an invulnerable army in this regard, and that he would be almost invincible when he went to the battlefield.

Of course, considering that the weaknesses are obvious, they can only be used as surprise weapons, but the effect they play is also terrifying. It is impossible for the enemy's chief general to understand the weaknesses of the vine armor in a short period of time. In this way, once they take action, the attack on the enemy will be devastating.

"This..." Ma Su couldn't think of any other methods other than fire attack when he heard this. After pondering for a moment, he looked at Liu Yi and said, "Since the sharp blade is not good, can you try a blunt attack?"

"Blow-hit?" Liu Yi's eyes lit up.

"Mr. Mo still remembers the killing and injury of the Mulu King's Bison formation to the army before?" Ma Su said with a smile.

"I can't find so many bisons in a hurry." Liu Yi smiled bitterly when he heard this. The family of King Mulu was just those bisons. They were almost dead on the battlefield. Now they probably have turned into feces. It will take time to get it out. In fact, Liu Yi had thought about using elephant soldiers to break the vine armor before, but according to King Mulu, the entire Bana Cave had only one elephant, and the white elephant he sat down.

Ma Su shook his head and smiled, "Mr. Mo has always been quick-witted, why is it unclear at this time? I just say something similar to the practice of the wild buffalo Pojun, not that you must use a beast to break the vine armor."

Liu Yi was slightly stunned, then reacted, patted his head and smiled, "If you remind me frequently, you will almost get stuck."

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

Thinking of this, Liu Yi said, "But if you use a chariot, you will have quite strict requirements on the terrain."

Tanks are suitable for use in plains, and it is best if they can fight low at high levels. In this southern and central area, there are not many terrain suitable for chariots to gallop.

Ma Su nodded and said, "That's true, but it's not without it. It just takes some effort to lead the vine armored army."

"Not bad." Liu Yi nodded and said, "In addition, a brigade's partial division needs to cut off its foundation after Meng Huo sent troops. I don't want to continue this battle."

This battle has been fought for too long, and the hearts of the people of the barbarians have almost stabilized. Next, what Liu Yi needs to do is to develop and do infrastructure in this southern middle place, rather than to get entangled with Meng Huo and other remnants.
