The last problem Tan Lun mentioned is the food issue.

Yan'an Prefecture is a hilly plateau with thousands of ravines and ravines, and is prone to drought and rain. Not only does it have a small area of ​​land that can be cultivated, but its yield is also very low.

The main grain crops are millet and millet, and there are also a small amount of wheat.

Millet and millet are OK as mixed grains, but as staple food, the yield is too low and the taste is not good.

However, wheat has relatively high requirements for terrain and rainwater, so if you want to increase grain yield in this natural environment, you either expand the arable land area, cultivate better wheat seeds, and accumulate various fertilizers to increase ground fertility and increase yield per mu.

But these two points are not possible at present.

Then the second method is left, which is to change to a staple food crop that is more suitable for the climate and environment of Yan'an Prefecture.

Corn is much more suitable than wheat.

Corn is not as delicate as wheat. It has strong cold resistance, cold resistance, barren resistance and excellent environmental adaptability. It has high nutritional value and a per mu yield is much higher than wheat.

As a staple food, corn can be steamed buns, made noodles, used to make porridge and make other foods, and the taste is also very good.

Corn has a very high vitamin content, 5-10 times that of rice and wheat. Among all staple foods, corn has the highest nutritional value and health care effects.

Even the layer of corn squid outside the corn has a good health care effect, and it has the saying that "one corn squid can be called two taels of gold."

Corn stalks can be used as fuel and can also be used to raise livestock.

As for corn as it is still a very important chemical raw material and pharmaceutical raw material, it is naturally not necessary to mention it now.

No foundation.

However, it is enough to have so many advantages as food, so corn is also known as "corn".

The sowing time of corn is usually in April and May, and the harvest time is around the end of September and October.

Even later, after harvesting wheat in May and June, you can sow corn in the wheat field without wasting ground power.

So Li Xu planned to change the planting of corn in Yan'an Prefecture, of course, he must first try planting in all labor reform farms.

It is difficult for ordinary people who know nothing about corn to accept the new crop of corn from the beginning, so Li Xu planned to let the prisoners in the labor reform farm grow first for the people to see.

When I see that corn is so good, easy to handle, with high yield and good taste, I will definitely spontaneously and proactively ask for planting in the future.

There are also potatoes, which are more suitable for planting in this kind of mountainous and hilly area.

You can plant any piece of land in the valley. It has a large yield and is cold-resistant, and has a variety of ways to eat it. It is still very good to supplement the staple food.

The combination of corn and potatoes, after several years, will definitely increase the grain output of Yan'an Prefecture several times, and then it will feed more people.

With more population, we can naturally train more troops.

It can be said that in an era of low productivity, food is the key to truly determining national strength.

Those who get food will win the world.

...

After talking about some of the main arrangements and arrangements, Tan Lun mentioned the Wei envoy who was also captured and asked Li Xu how to deal with it.

Li Xu thought about it and said that killing this person is very simple to see if it has any value to use.

Tan Lun said that this guy had a hard bone. Although he was beaten miserably, he had basically not spoken of valuable information so far.

Li Xu said that this person was a Qianhu of the Wei State Department. He was originally a spy organization and must have received corresponding captured training.

In addition, this person can be elected as the Qin State as this special envoy, in addition to his ability, he must be a tough guy.

Besides, their families are generally controlled by the Wei court. If they really dare to betray, the whole family will definitely not be able to survive.

It even involves other relatives.

The bones themselves are hard and the cost of betrayal is high, so the general interrogation method is definitely difficult to work.

Tan Lun nodded and agreed with Li Xu's judgment, saying that if there was a way to pry open this guy's mouth and at the same time dispel his concerns, he could use this person to spread the intelligence network to the State of Wei.

As for prying open his mouth, Li Xu thought for a while and suggested that Tan Lun try to close the small dark room for this guy.

The power of the small dark room is not to make people physically painful, but more importantly, it makes people fall into a mental breakdown step by step in the narrow, dark and closed environment, and finally know everything.

Although Tan Lun was a little unbelievable when he heard this, he nodded and tried it.

As for dispelling the concerns of Wei's special envoy, Li Xu smiled and said, "Zi Li, have you forgotten the mission of this person to sneak into Qin?"

Tan Lun was stunned, and suddenly realized, and laughed: "The lord woke up the dreamer with his words."

The other generals were a little confused, and Tan Lun saw it and explained:

"The purpose of this person coming to Qin was to instigate the high-bearded rebellion to attract the attention of the Qin court, so as to constrain the Qin army on the border.

But now that the tall beard has been destroyed by us, his mission is naturally failure.

But now we have replaced Gao Huzi, and we are obviously stronger than Gao Huzi. After we make a banner in the future, we will definitely attract the attention of the Qin court, so we are more suitable to cooperate with him than Gao Huzi.

Of course, the people of Wei used to treat tall beards as cannon fodder.

If they want to cooperate with us, they must cooperate in the way we agree.

At that time, we will hold his handle in our hands and provide him with the opportunity to continue to fulfill his mission. How could he not be willing to cooperate with us?"

The generals suddenly understood as soon as they heard this, and they called the lord wise.

Li Xu smiled and accepted the flattery of his subordinates.

For him, this is just a small matter, just talk.

The specific matters still need to be concerned about Tan Lun and the others.

Speaking of intelligence networks, Li Xu suggested setting up another MIIS under the General Staff and also setting up an intelligence structure under the Yanzhou General Administration.

The former is equivalent to an intelligence agency in the army. It is mainly responsible for collecting, screening, analyzing, identifying and judging various types of military intelligence, and provides them with reference for generals to arrange troops.

The business scope of the intelligence agency under the Yanzhou General Administration will be more extensive and comprehensive, and the scale will be larger.

Tan Lun deeply agreed and asked Li Xu to give the intelligence agency a name.

Li Xu thought about it and the official name was the Consulting Department, code-named "Ye Xiao".

At that time, we will announce to the public that this is a staff organization under the Yanzhou General Administration, as the name suggests, you will know.

Li Xu said that he would send some professional spies to serve as backbone first, put up the "Ye Owl" airs first, and gradually improve the rest.
