Zhang Kang only passed on the news of Dong Zhuo's death, but did not mention what he wanted to do next.

Cai Yongkong Rong and them were also depressed, and it was difficult to bring it up.

From their point of view, now that Zhang Kang is in charge of the imperial court, the timing is just right......

If it is because of Wang Yun and Lu Bu, the imperial court can return to the situation of the Imperial Forest Army and the Xiyuan Forbidden Army.

Then Zhang Kang controls the guards in the West Garden, and he can also do something......

"I know what you mean, wait another three months! I will write to Your Majesty when I am ready. ”

Zhang Kang was noncommittal and directly proposed a point in time.

He could never say that Chang'an, under the leadership of the poison army division Jia Xu, was more terrifying than when Dong Zhuo was in power.

Not to mention anything else, even the invincible Lu Bulu Fengxian, who was in charge of the heavy troops of the Beijing Division, was not beaten and fled......

Qingzhou Mansion Yahou Hall.

At this time, Zhang Kang wandered back and forth in his study, and next to him, sitting at the desk, was Cai Wenji and her little follower, Jian Qian, the little sister of the Jian family.

A few rays of afternoon sunlight shine into the room, reflecting the whole room magnificently.

Well! During work hours, the three of them are crowded here, but they are not afraid of causing gossip, especially not worrying about Cai Yong breaking in.

Zhang Kang has business to find Cai Wenji.

Although many people can also be competent for this business, Zhang Kang persuaded the Cai family father and daughter on the grounds of confidentiality.

Because Zhang Kang wants to write a book and speak.

As a result, the evil consequences of the original Zhang Kang's lack of learning and unskilled skills were shown.

I can't write!

Zhang Kang could search for the information he needed from the Earth Edition: Encyclopedia, but the problem was that he couldn't do anything about it when it was written in the Three Kingdoms period.

The ability of the original Zhang Kang is probably like barely writing the name of the family.

Helplessly, I can only find Cai Yong's family for this matter, who made his family all Wenru.

Qingzhou is in ruins, and Cai Yong is busy with official business, so he has to let his daughter come out to help.

The main thing is that Zhang Kang guarantees that the place of work is in the government office, and he is accompanied by Jian Qian, so don't worry.

Shame on you!

As a modern poet who has read poetry and books, and has the backing of systematic encyclopedias, he has been unable to find sustainable projects for more than a year.

The people live on food!

This is a development plan that has been attached great importance to by those in power throughout the ages.

Zhang Kang is no exception.

The area under his jurisdiction is basically a region-wide mobilization, and the military and civilians are united.

Or hard indicators, army tuntian. Or a soft landing, on the grounds of profit, mobilize the people to reclaim fertile land. All newly cultivated fields belong to the reclaimers, and if they do not pay grain for three years, the state government guarantees to buy them at market prices.

Even, because of the war disasters in Qingzhou for many years, there are few people in the land. Even so, grain production is not optimistic.

This problem, even in the early stage of industrialization in later generations, when there was a lack of pesticides and fertilizers, the grain yield per mu could only be maintained at about 300 catties. Not to mention the era when there were no pesticides and fertilizers at all.

If you want to talk about the information and technology for refining pesticides and fertilizers, Zhang Kang also has them, but he doesn't dare to make it out.

These technologies do not form a technological fortress, and once invented, such an important technology is believed to soon spread to the entire Han Dynasty.

If it's a peaceful and prosperous world, it's fine.

For the benefit of the country and the people, Zhang Kang will naturally not stop it.

The problem is that the chaos has just begun, and once the major princes have this technology, the situation will become more and more uncontrollable.

Zhang Kang has not forgotten that the so-called pesticides and fertilizers, in other words, these are also poisons!

In fact, the poison of these years is basically poisonous, and it relies on a large amount of water......

For example, the legendary arsenic actually takes half a catty to a catty at a time to poison a person. Just think about it, the taste is so strong, the amount is super scary, and it can be so poisonous that people are weird. But these pesticides are different, once invented, they can be used as poisons.

Since chemical fertilizers and pesticides are not suitable for tinkering for the time being, then grain production should not be increased. The only way to make up for the lack of yield is to use more arable land.

As for the three major items of sweet potatoes, potatoes, and corn, which are the key to completely solving hunger in later generations, they are now available on the earth, but unfortunately they are not in Dahan. Zhang Kang is not able to bring in these three treasures for the time being......

Since farming is not feasible, let's engage in farming!

Zhang Kang's first thought was to raise pigs.

How can modern people not know the importance of pigs?

Pork is even important enough to influence the livelihood of a billion-dollar superpower.

As a result, as soon as Zhang Kang proposed the project, he immediately rejected it to everyone.

Pork is only suitable for small-scale free-range farming.

This is the conclusion reached by Zhang Kang after comparing many aspects.

The reason is simple, what pigs can eat, people can also eat. People can't eat enough and still expect pigs to be full?

A pig, starting with a piglet, and when it is ready to be slaughtered, the food wasted by the pig is worth more than the pig itself.

What else?

Zhang Kang completely forgot that the food that pigs ate this year can also save people's lives.

As a result, only grazing cattle and sheep are left to consider in his farming business......

Inventing explosives that can kill people?

Zhang Kang quickly denied himself. The tech fortress is the key!

Limited to resources, don't produce one catty by yourself, other princes can produce a hundred catties, and harm others will not end up harming themselves.

Cement? Bitumen? Developing infrastructure buildings? Don't be stupid, you own less than one percent of the territory, and the development will do more harm than good.

In this way, Zhang Kang struggled for a year, his hair turned gray three times, and finally only a few bars of soap came out.

This thing can't be imitated by others for a while.

Even if the technology is leaked, the harm is not high, and it is especially suitable for making the wealth of the rich in other regions.

Other aspects that can be thought of, this is also the reason why Zhang Kang asked Cai Wenji for assistance.

If you don't dare to make big inventions, you can still make small improvements in farming, breeding, and so on. For example, tools, grafting, insect control, etc., these technical knowledge can be basically solved by a book of "Qi Min Yaoshu".

It's not too advanced, but it can improve the current efficiency a bit......

Today, Zhang Kang asked Cai Wenji to copy the knowledge about shipbuilding.

Shipbuilding has always been the strength of China, think about the building ship built by Qin Shi Huang, it is a tall ship. It also lives up to its name. The hull is divided into three to five layers, and buildings are built on the ship, so it is called a building ship. It is usually more than ten zhang high and can carry up to 3,000 soldiers.

Zhang Kang just wanted to make the famous three-masted ship come out in advance on this basis.

From the Ming Dynasty to later generations, it has been proved that the three-masted ship is the overlord of the sea in the age of sails, and it is the pinnacle of warships after the Age of Discovery.

Zhang Kang just wanted to improve a little, so that the boatwright could be inspired, or he could create something unusual.

The three-masted warship is actually better than the Lou ship or the lucky ship of the Song and Ming dynasties, in fact, in terms of speed.

Zhang Kang also doesn't know if he can make it out with his current production capacity.

Anyway, he only proposed, and it was Xun Yu's business to solve it like this......
