The room goes through the late Ming Dynasty, and the back door leads to North America at the beginni

After hearing Li Changwen's words, Liu Sheng laughed and immediately took a sweet potato from the field and handed it over.

"Whether it tastes bad or not, Master Li will know after one bite."

Li Changwen took the sweet potato without washing it. He scraped off the soil on it and started to eat it.

He ate gracefully, first biting open the dusty skin, and then nibbling the flesh inside.

The sweet taste surprised him again!

Liu Sheng continued: "Sweet potatoes can be steamed, fried, or stir-fried, and can be used to make many kinds of foods. With the right method, they can be stored for several months.

If the sweet potatoes are dried, ground into sweet potato flour, or even made into vermicelli, the storage time can be measured in years.

The only disadvantage is that if you eat for a long time or eat too much, it will easily cause abdominal distension.

By the way, the young leaves of the sweet potato vine are also a good vegetable, and the harvested vine leaves can be fed to livestock such as pigs, cattle, and sheep. "

Hearing Liu Sheng talk about the many uses and advantages of sweet potatoes, Li Changwen felt numb with surprise.

Then he remembered what Liu Sheng had said before, that Xu Guangqi had written "Sweet Potato Sparse" and reported it to the court, asking for the promotion of this product.

But in a large agricultural province like Henan, he had never heard of this thing.

Needless to say, the court probably didn't do this. Or maybe it was done, but failed due to various reasons.

Thinking of Henan, Shaanxi and other northern provinces, there have been years of drought. I don’t know how many people have starved to death due to poor harvests.

The Ming Dynasty had Xu Guangqi to play "Sweet Potato Thinning", but it could not promote the planting of sweet potatoes.

He was so angry that he trembled and said angrily: "It is such a good thing that God has given to people to survive in disaster years, but the imperial court cannot promote planting. Instead, it makes hungry people everywhere and wars everywhere. It deserves to die! It really deserves to die!"

"The Ming Dynasty has reached this stage and it is indeed time to die."

Liu Sheng followed, but his tone was calm.

Like stating a fact.

Then, he took Li Changwen to another several hundred acres of sweet potato fields.

"The seeds of those sweet potatoes just now are improved varieties brought from my home, and the yield is indeed very high. However, the number of improved varieties is not large, and they may deteriorate.

If you want to promote the planting of sweet potatoes on a large scale, you have to rely on potato seeds from North America.

Native Americans have been cultivating sweet potatoes for at least thousands of years. Unfortunately, most of them use slash-and-burn cultivation, and they have not done enough to cultivate high-quality potato seeds.

If we cultivate their potato seeds intensively, we will definitely be able to harvest more, but it will definitely not be as good as the improved seeds I brought out. "

While talking, the three of them had arrived at another sweet potato field.

Li Changwen only looked at the sweet potato vines in these several hundred acres of land, and found that they were different from the previous one hundred acres, and seemed to be more lush.

However, sweet potatoes are fruits buried in the soil, and lush vine leaves may make the fruits smaller.

Sure enough, He Guiyou dug out another batch of sweet potatoes. Although there were as many as seven or eight sweet potatoes growing underneath, the largest ones were no bigger than a fist. Most of them were only as big as duck eggs or chicken eggs.

He Guiyou said: "The potato seeds exchanged from the natives are not as good as the fairy seeds given by the boss. I estimate that this acre of land can only yield 500 to 600 jins. It is difficult to exceed 700 jins."

Li Changwen didn't feel disappointed.

He smiled and said: "It is not bad to be able to harvest five to six hundred kilograms per acre. It will not compete with rice and wheat for land. People can plant sweet potatoes in barren dry lands and mountains at the same time as rice and wheat."

If people all over the country could grow a few acres of sweet potatoes a year to supplement their crops, they would not be starving to death in large areas like today. "

After inspecting the fields, Liu Sheng took Li Changwen to visit the workshops and kilns.

Li Changwen discovered that although the Chinese Department in North America currently has less than 30,000 people, it has many institutions with clear division of labor and well-organized operations.

It can be seen that Liu Sheng not only has strong military talents, but also has considerable knowledge and ability in civil affairs.

It even made Li Changwen feel that he was inferior to Liu Shengqiang in civil affairs.

To show talent.

While having dinner with Liu Sheng in the political hall, Li Changwen asked: "What does the leader think is the most urgent thing for the rebels at the moment?"

Liu Sheng said without thinking too much: "Of course it's troop training - before, including the fishing and hunting group, we only had an army of 1,600 people.

In Queshan County, we requisitioned 70,000 to 80,000 shi of grain, but only transported more than 10,000 shi back to Tianmu Mountain. We had to leave 400 standing troops to garrison the county.

Although I left 2,800 strong men in the county seat to supplement the garrison and train civilian bravery to assist in the defense of the city.

But it is difficult to form combat effectiveness in a short period of time. If Fucheng can mobilize troops to attack Queshan within half a month, things will not be good.

Therefore, we still have to send people to transport the county's food back to Tianmu Mountain as soon as possible.

However, troops must be sent to transport food, otherwise food security cannot be guaranteed.

However, with so many new immigrants coming to the North American camp and more than a thousand prisoners, a certain amount of troops are needed to guard them in order to make people feel at ease. "

Li Changwen was slightly surprised. He didn't expect that Liu Sheng's biggest worry at the moment was how to transport grain from Queshan County to the mountains.

Immediately he put down his bowl and chopsticks and said: "I also believe that the most important thing for the rebel army right now is to train and expand the army, and to expand the army greatly!

The shortage of troops to transport food and the shortage of troops to guard the four major battalions that the leader just mentioned are actually trivial matters.

The most important thing is to attack the rebels before the imperial court pays attention to them, and to gain a piece of territory that is sufficient for the rebels to move around! "

After a pause, Li Changwen dipped his hand in water and first drew a mountain peak on the table, and then drew a circle to encircle it.

"Tianmu Mountain is only a small area in the world. If the imperial court pays attention to the rebels, it only needs to send tens of thousands of officers and soldiers to encircle and suppress them, and the rebels can be blocked in the mountain.

In that case, even if the leader has the magical power to bring people to this blessed land in North America, it will be difficult for him to accomplish much in a short period of time.

At that time, they will either surrender and be surrendered by the court; or they will have to wait for drastic changes in other parts of the world and the court will be forced to withdraw their troops, so that the rebels can break the blockade.

But that would be too passive and may miss the opportunity for rapid development and expansion. "

Liu Sheng nodded repeatedly after hearing these words. He had long been worried that Tianmu Mountain would be blocked by enemy troops.

Although it is not difficult to see this, Li Changwen's ability to say it shows that he does have a strategic vision.

Li Changwen added: "My subordinates in other places don't know much about it, but in Henan alone, disasters have continued for several years.

This year, severe drought and locust plagues have come one after another. However, the Ming court did not provide relief to the victims, but instead increased taxes.

Runing Prefecture occupies the water conservancy areas in the upper reaches of the Ru and Huai Rivers, and is considered to be a place less affected by drought in Henan.

Nowadays, hungry people are everywhere and bandits are everywhere. You can imagine what the situation is like in other places.

Not surprisingly, Henan will undergo major changes a year ago.

The imperial army was either encircling and suppressing the Eight Kings, Li Chuang, Cao Cao and other rogue bandits in Sichuan, or they were transferred outside the pass to resist the Jiannu.

There are many hungry people in Henan. Once something changes, it will soon sweep through the entire Zhongzhou and then spread to several surrounding provinces.

The situation at that time was probably even worse than a few years ago when dozens of rogue bandits wreaked havoc in Henan and Jiangbei.

But if the leader wants to lead the rebel army to rebuild the world, he needs to take advantage of this great change. If we miss it, the future of the Rebel Army will probably be much more difficult. "
