Technology dominates the Three Kingdoms

Chapter 274 Mission, Steel Filling Method
In a blink of an eye, it was mid-May in 190 AD.

Corn planting and rice transplanting are in full swing in Jiaozhou.

Many people have tasted the benefits of sweet potatoes, leaving some land or reclaiming new land to grow sweet potatoes.

In this regard, Lu Bu did not make a mandatory requirement.As long as the new corn and rice are planted on a large scale, people will always realize the benefits in the harvest season, and there will inevitably be trade-offs at that time.

In addition, just yesterday Lu Bu received a reminder from the system that he completed: [Task requirements: within half a year, establish Huashen Medical College and Sinonong College, with thousands of teachers and students in each college. 】

[Task Reward: 2000 million points reward points, unlock [Revised Edition of Wang Zhennong's Book], [Magpie Internal Classic, External Classic], [Huangdi Internal Classic], [Difficult Classic], [Revised Edition of Compendium of Materia Medica], [Chinese Pinyin Teaching Book], [Thousand Characters, Hundred Surnames, Pinyin Version of the Three Character Classic], [Shen Nong's Herbal Medicine]].

This batch of rewarded books is more important to Lu Bu. After a certain amount of points are consumed, they are redeemed and ordered to be engraved and printed in secret.

There were few things to do this morning, so Lu Bu was in charge of giving a lecture to Lu Lingqi. He talked about the importance of timely delivery of information in battlefield operations, so he talked about carrier pigeons.

Lu Lingqi was very interested in carrier pigeons, so she begged Lu Bu to take her to see how carrier pigeons deliver letters.

There was no other way, so Lu Bu had no choice but to take her to a remote courtyard in the mansion, but it was guarded by the Shenbing Battalion.

Constantly looking at the soldiers of the Divine Army Battalion around them, all of them looked extraordinary and brave, Lu Lingqi muttered and said, "Father, when do you think I will have the skill and force of the soldiers of the Divine Army Battalion?"

Lu Lingqi, who dreamed of fighting side by side with her father since she was a child, wished she could grow up right away. Not to mention being comparable to Lu Bu, at least she should be no worse than the soldiers of the Shenbing Battalion, so that she could fight side by side with Lu Bu.

Hearing his daughter's words, Lu Bu couldn't help laughing, patted her head, and said, "Don't aim too high, be down-to-earth, and have confidence in yourself. You are still young, and the soldiers in the Divine Army Battalion have cruel basic training and experience. Life and death have been tempered, and it is not something that can be achieved by talking about it.”

The training of the soldiers of the Shenbing Battalion is a training program set by Lu Bu himself. He is a special soldier, so the "devil-style" training is also adopted for the Shenbing Battalion.

"Oh, my daughter has been educated, so she won't aim too high in the future, and she won't let her father down." Lu Lingqi clenched her fists and her gaze was firm.

Not long after, the father and daughter came to the room where the pigeons were raised.

There are several rooms in the courtyard, all of which have been repaired for the survival of homing pigeons.

There is a room for breeding young carrier pigeons, a room for training carrier pigeons, and a place for delivering and receiving letters.

Lu Bu kept briefing his daughter on the process of cultivating carrier pigeons, and when they were about to go back, they encountered a carrier pigeon flying from the west.

It was sent by Jia Xu from Cangwu County, a report on the war in Jingzhou.

Zhang Liao and Hao Meng want to use carrier pigeons to convey the battle report, they need to send it to Jia Xu first, and then send another carrier pigeon to the General's Mansion.

That night, Lu Bu received another prompt from the system:

"Congratulations to the host. In the past three months, more than 210 million acres of new paddy fields have been reclaimed in Jiaozhou."

[Task Reward: Complete the task, reward [-] million points, and the part exceeding the task will be calculated as [-] points per mu. 】

[Mission Unlocking; [Secret Method of Sugar Making], [Thread Technology], [Propeller Design Drawing], [Brick Kiln Secret Technique], [White Glazed Porcelain Technology], [Ball Exchange], [Watertight Bulkhead Design Drawing], [Eastern Han Dynasty Atlas】】.

Prizes have been distributed, please pay attention to check. "

At this time, Beast, who hadn't shown up for a long time, said loudly: "Dear host, congratulations, you've made a fortune again, and you've got more than 2 million points!"

Lu Bu didn't like it very much. It seemed that the beast came here to collect the points he owed, and asked angrily: "I don't have any good intentions. I haven't seen you for a long time. I thought you died. Tell me, How many points does my uncle have now?"

It is the grandson who borrows the money, and the uncle who pays the money back!
"Hearing what the host said, Beast is so sad..." Beast's voice became more and more feminine, "Host, you still have 421, 635, 21 points left in your points."

No, Lu Bu felt very wrong, and questioned: "No, I remember that there were more than 5000 million before, and after completing the task of recruiting students for the construction of the two colleges, I got 2000 million, and I got more than 2 million after completing the task of reclaiming new paddy fields. There are at least 5000 million points for rice seeds, why..."

Suddenly he thought of something, despised the beast and said: "I see, you are the one who collected the [-] million bills, okay, don't notify in advance, look down on people..."

However, he wronged the beast, and the beast said aggrievedly: "The host will bully the beast, the beast is so pitiful. It is obvious that the system deducted [-] million points, but it is said that the beast did it, so sad..."

... Lu Bu was instantly embarrassed: "Is... so?"

Your sister, the system is still overbearing and cheating as always!

Then Lu Bu comforted Beast for a while in embarrassment, and then... he was speechless all night.

On the second day, Lu Bu went to Jiang Lie, who was in charge of making weapons.

Lü Bu was satisfied with Jiang Lie's secret assessment recently, and today he plans to hand over the "steel pouring method" to Jiang Lie, so as to realize large-scale steelmaking as soon as possible.

Strong weapons are king.

Before that, Lu Bu had a general look at the steel filling method exchanged from the system. In addition to the detailed records of the steel filling method, there are also detailed records about: the block smelting method and the steel frying method, which are very precious.

About block refining method and fried steel method:
"Block smelting method", the ancient smelting technology was in a relatively primitive stage before the Spring and Autumn Period, and the smelting method used at that time was called "block smelting method".

At that time, charcoal was used as fuel for ironmaking, with little heat, small furnace body and poor blasting equipment, so the furnace temperature was relatively low and could not reach the melting temperature of iron, so the iron produced was a spongy solid block, called "A piece of iron smelting".

Its characteristics: it is time-consuming, the texture is relatively soft, and it contains many impurities, but it becomes usable wrought iron after forging.

And "fried steel method": In the middle and late Western Han Dynasty, a new steelmaking technology "fried steel" appeared in China. This is a steelmaking technology developed on the basis of pig iron smelting and casting technology.

The method is: heat the pig iron into a semi-liquid and liquid state, then add iron ore powder, and at the same time keep stirring, use the iron ore powder and oxygen in the air to remove part of the carbon in the pig iron, reduce the carbon content in the pig iron, and remove the slag , to directly obtain steel, which is the technology of frying steel.

Finally, there is the "steel filling method".

The steel-filling method in history The initial form of the steel-filling method, a new steelmaking process, may have appeared around the end of the Eastern Han Dynasty.

During the Southern and Northern Dynasties, some people made major improvements and perfections to this steelmaking process.Tao Hongjing of the Qi and Liang dynasties in the Southern Dynasties first recorded the method of pouring steel, and Qi Wuhuaiwen of the Wei and Qi Dynasties of the Northern Dynasties once used this method to make a very sharp "Su iron knife".

Of course, the steel pouring method exchanged from the system is better than the one in history, and it is a perfect manufacturing technology and process.

In addition, there are blast furnace design drawings and explanations related to ironmaking and steelmaking.

It is worth noting that there are also design techniques and processes for screws and springs.

It's rare, Lu Bu thinks that the products produced by the system are really exquisite!
This was the first time that Lu Bu didn't feel that he was at a disadvantage!
