The most arrogant in history

Chapter 169 The annoying little goblin.

In the military discussion hall, the students were all sitting and waiting.

Seeing Ye Kun, everyone stood up and saluted.

Ye Kun nodded and started the class. Based on the last battle of Jigongling, he once again taught everyone how to draw battle maps and conduct sand table simulations.

The art of war says that if you know yourself and your enemy, you will win every battle.

But it is very difficult to know both yourself and your enemy.

Many generals are unwilling to put in the effort before a battle, and rely on their subjective assumptions and on-the-spot experience to fight, and victory or defeat depends entirely on courage and luck.

After explaining the map and sand table, Ye Kun took a short break and changed the topic:

"Classmates, how many casualties do you think a 10,000-man army would have to suffer in a war before their morale would be affected and they would collapse?"

People were chattering, some said they would collapse if they lost half, while others said they would collapse if they lost more than half.

"I'm telling you."

Ye Kun waved his hand and said, "Those scattered soldiers who were temporarily organized have weak cohesion. If they lose 10% of their troops, the whole army will collapse. Even if it is the most elite army of the various princes, if the loss rate reaches 30%, the whole army will collapse."

Everyone was shocked.

A student asked, "Master Ye, does this mean that when we fight, we must keep the casualty rate below 30%?"

"Wrong!" Ye Kun said seriously:

"My request to you is to never collapse. When you lead troops to fight in the future, you must not give up the fight even if you are down to the last man. If the city gate is lost, we will fight in the streets! When we run out of arrows, we will fight hand-to-hand! If there are 10,000 troops, you are the general. When there are only three people left, you will be the leader of the combat team! As long as you have this strong spirit, you will be an undefeated god of war!"

The students were inspired and stood up collectively:

"Fight to the end and never retreat!"

Ye Kun was very satisfied and nodded:

"Everyone has experienced the last battle of Jigongling. Go back and write a battle strategy and battle summary of no less than a thousand words. Submit it to me next week... no, after seven days."

In the battle of Jigongling, more than a thousand enemies were killed. Only three of Ye Kun's men were seriously injured, five were slightly injured, and no one died.

This is another masterpiece of Ye Kun.

When the students heard that they had to write an essay, they all looked embarrassed.

“If you’re not afraid of death, why are you afraid of writing an article?”

Ye Kun frowned and said, "After seven days, those who fail to submit a battle summary will be punished by military law. Also, plagiarism is not allowed!"

"As ordered!"

The students took the order together.

Ye Kun announced the end of get out of class and took Qin Caiwei to see something fun.

By the small river outside the city, Qin Chou and other officials in charge of agriculture were learning how to set up and use water wheels.

Qin Chou and others were seeing this thing for the first time. They rolled up their trouser legs and sleeves to experience the fun of driving the water.

"Hey, this is fun!"

Qin Caiwei's eyes lit up, he looked left and right, and then he drove a few circles himself, and said with a smile: "Master Ye, please give me this waterwheel."

Ye Kun sighed, "Mr. Qin, the manufacture of this waterwheel is very complicated. It requires a top-notch carpenter and an apprentice to build it for a full hundred days. But since you asked, how can I refuse? When you go back, I will give you a waterwheel and the blueprints."

When Qin Caiwei heard Ye Kun talking about the difficulties at first, he thought he was reluctant to give it up. But when he heard that there were blueprints, he couldn't help but be overjoyed: "Master Ye is really generous, thank you very much!"

Ye Kun was very busy and listened to the report from agricultural officials on the spot.

At this time, wheat harvest is about to begin.

Ye Kun had discovered long ago that there were scattered rapeseed seeds in the countryside, so he asked the officials to notify the village heads to pay attention to collecting the rapeseed seeds. One pound of dry rapeseed seeds could be exchanged for three pounds of fine grains, and he would take as many as he could.

The edible vegetable oil of the Dading Kingdom was sesame oil, which was made from sesame seeds and technology introduced from the Western Regions.

Rapeseed can be used to produce oil, but the people of Dading Kingdom have not discovered it yet.

The rapeseed in Dading Kingdom is grown as a vegetable. After the rapeseed grows moss in spring, it is old and will be removed, leaving only a small amount for seeds.

Ye Kun collected these seeds and planned to plant them in the fall.

Ye Kun also asked each village to purchase the kernels of peaches, apricots and plums and directly exchange them for grain.

Almost all nuts can be used to extract oil. Ye Kun collected nuts to do an oil extraction experiment because the people were suffering so much that eating oil was a luxury.

Developing the edible oil industry can improve the lives of local people and generate huge financial resources in the future.

In this way, exchanging food for the people further ensures their food and clothing.

Two months ago, the people of Dongba County were still struggling to survive by gnawing on tree bark and digging grass roots. Now, through working for Ye Kun and exchanging food in various ways, they have basically solved the problem of food and clothing, and even every household has 10 to 8 kilograms of surplus food.

After finishing the farm work, Ye Kun took Qin Caiwei to Guan Yafu's house to see the grafted fruit trees.

Last time I grafted apricot trees onto peach trees, there were four branches in total, and three of them have survived, which is a great honor!

Guan Yafu came back to entertain the guests and said with a smile:

"Master Ye, I am really impressed by you. Most of the fruit trees you grafted last time have survived. I just don't know if they can bear fruit in the future."

"Don't worry, those grafted fruit trees will have branches next year. When the time comes, I will come to your house and discuss heroes with Lord Guan over green apricot wine."

"It's a deal." Guan Yafu nodded.

Qin Caiwei looked at the apricot tree grafted by Ye Kun, but he was not very interested: "Master Ye, this one is not interesting, do you have any other ones?"

"Yes, in the evening."

Ye Kun nodded, said goodbye to Guan Yafu, and quietly instructed his personal soldiers to go to the gunpowder factory in Dongba City and ask the workers to quickly make a batch of fireworks sticks.

Meeting Wei Caiqin, this annoying little goblin, Ye Kun could only consider himself unlucky.

After returning home, Ye Kun called Lao He again, drew a blueprint of a rocking chair, and asked Lao He and the carpenter to make it.

The chair's four legs rest on curved seesaws and can rock back and forth.

A pad is added under the seesaw, and magnets are hidden on the pad and the seesaw in relative position. The front and back are set in the same way. According to the principle that like magnets repel each other, the chair will automatically shake continuously when subjected to a slight force.

This thing is not difficult. A few carpenters can make it by working overtime.

Qin Caiwei was thinking about the concert at Xidaying in the evening, so he went back to the inn to take a nap.

Ye Kun also had a moment of peace to perfect the hydraulic woodworking lathe he had been conceiving for a long time.

Today's carpenters can make a lot of things, but their efficiency is too slow.

The slowest step is sawing the boards.

When young carpenter apprentices become apprentices, they do nothing in the first year but pull the big saw. Now they all have strong arms.

Moreover, the quality of the saws is not good. When cutting large wooden boards, it takes two people a whole day to make one piece, and they are often not suitable for use.

Dongba County is rich in hydropower resources and has numerous rivers.

Ye Kun had already chosen the location and dug two parallel river channels.

In the middle of the two river channels is a one-kilometer-long straight dam. In the future, a large number of hydraulic lathe equipment will be installed on the dam to improve efficiency.

Because it has been conceived for a long time, the blacksmiths and carpenters have made several sets of various parts, and now they are waiting for assembly and debugging.

For the saw blade of the sawing machine, Ye Kun used a disc-type saw blade, which is made of tempered steel. He hopes it can be used.

The main shape of the sawing machine is similar to the later woodworking table saw, except that it has hydraulically driven wood pulp discs on both sides, and it occupies a large area.

At dusk, Ye Kun went to Lao He's laboratory and took several master craftsmen with him to assemble the machine and conduct manual testing first.

The effect is okay, much easier than using a big saw, but it cannot cut large materials.

Lao He said: "This thing can be used if it is designed to be pedal-powered. It just needs to be assembled with a pulley set."

Recently, I have been learning about movable pulleys and fixed pulleys, as well as the calculation formulas for levers with Ye Kun. Lao He is very proud of himself.

"Hydraulic power saves money and a lot of manpower, but it requires a fixed location and is subject to restrictions. Manpower is very tiring, but it is not restricted by site conditions. So, let's develop both together."

Ye Kun patted Lao He on the shoulder:

"The human-powered pedal saw is now handed over to you. Note that it is designed so that one person can pedal and one person can operate it. This way it will be faster. The person in charge of pedaling only needs to be strong, not skilled."

"Don't worry, Lord Ye, I'll get it done for you in two days!"

Lao He is very confident.

After returning to the county magistrate's mansion, Ye Kun took a shower and was about to coax Teacher Wen to sleep when Qin Caiwei came to ask for a meeting again.

This girl watched the military exercise and condolences at the West Camp and came to harass Ye Kun again.
