"Where did you know that?"

Lu Yuan was a little curious, where did Li Shimin know these things?

"I found out in a casual conversation with a friend surnamed Jiang. ”

Li Shimin replied honestly.

"The surname is Jiang, Jiang Wen, I see. ”

Hearing this, Lu Yuan immediately knew who the person who told Li Shimin about these people was.

Thinking of this, Lu Yuan also smiled slightly, how could he not know the purpose of Jiang Wen telling Li Shimin this.

It's nothing more than wanting to sell some advanced things to Li Shimin, and then get the boundary coins.

However, he has no objection to these, anyway, all transactions are carried out in the Wanjie Purchasing Tower, and they all need to pay taxes, so he will get benefits.

But the piece of meat with the biggest head must be his time to eat.

For example, this time, as long as he helps Li Shimin build three modern schools, then he can get a huge sum of 90,000 world coins, which is still very attractive to him.

"Your request, this immortal can help you do it. ”

Lu Yuan didn't think much about it, and directly agreed to their request.

Hearing this, the five of them were all happy.

"Not only can this immortal help you open schools and scientific research institutes, but it can also sell you things that will help you a lot. ”

Lu Yuan slowly said what he had thought about before. ad_250_left();

"What's that?"

When the five of them heard what had helped them a lot, they immediately perked up and looked intently at the sky.

"The people take food as their heaven, and this immortal can give you a seed with a very high yield, and if you plant the seedlings born from this seed, you will harvest a large amount of rice, which is enough to meet the needs of the people. ”

Lu Yuan smiled slightly, and said that he had thought of a profit plan, which was to sell grain seeds.

You must know that in ancient times, the grain production was very low, and some people did not even have enough to eat, and many people starved to death.

But now hybrid rice, the yield per mu is at least a few hundred catties larger, and there are good ones or even more than a thousand catties.

Even if the conditions in ancient times were not as good as those in modern times, the yield was far better than that of their seeds, and I don't know how many times.

It can be said that with the seeds he gave, there will never be a shortage of food for them again.

"How much is the yield per mu of seeds with extremely high yields?"

When the five of them heard this, they were all slightly stunned, and then asked curiously.

Subsequently, Lu Yuan told the corresponding yield according to the era where the five people lived, the area per mu, and the unit of output.

"Hiss......"

After hearing the numbers Lu Yuan said, these five people all gasped in unison, their eyes full of shock and disbelief.

This figure is so exaggerated that they never thought that the yield per mu could be so high.

If it is really according to the output that Lu Yuan said, then the people of the whole country can eat enough every day.

Not only can you have enough to eat, but you can also sell the surplus food to get some surplus money.

And when the people have money left in their hands, will there be less money in the treasury?

In just a moment, they thought of a lot, and their hearts couldn't help but burn, and their eyes were full of anticipation.

"Daxian, I want to buy this seed!"

"Daxian, I'll buy it too!"

The five of them scrambled towards the sky and said urgently, looking at their image, they didn't look like emperors at all.

"Don't worry, these things are there, as many as you want. ”

Seeing this, Lu Yuan naturally did not refuse to come, and sold as much as he wanted.

"Also, advanced steel-making techniques, this immortal can also sell to you, and sell you advanced steel-making equipment. ”

Subsequently, Lu Yuan threw another super move.

"Steelmaking and steelmaking equipment?"

Hearing this, these five people couldn't calm down, especially Ying Zheng, Yang Guang, and Li Shimin, their era was earlier, and steelmaking was naturally not as developed as the era of Zhao Ji and Xuan Ye.

In ancient times, the main thing in an army was weapons, and the most important thing in weapons was steel.

Li Shimin still deeply remembers that when Lu Yuan got 3,000 pairs of armor and Mo knives, the Turks killed on the battlefield were terrified and bloody, which is enough to show the importance of advanced steel.

Therefore, after hearing Lu Yuan's words, they all attached great importance to it, thinking that they must buy this advanced steelmaking technique.

"There are many, many things, this immortal will make a list, and show the usefulness of each thing, you go back and think about it, and after thinking about it, you will buy it from this immortal. ”

"When buying, if you don't have enough money, you can pay in installments. ”

Lu Yuan made a list, handed it to the five of them, and left them to study.

Subsequently, Lu Yuan left the Wanjie Purchasing Tower.

The five of them formed a circle and began to seriously study what was written on the list.

"Bicycles, new vehicles, two wheels, how is it possible?"

"Electric light, day and night?"

Several people's faces were full of blankness.

"Electric light, I know. ”

Li Shimin's eyes lit up when he saw the electric light, last time he had seen this kind of thing that could shine all the time without igniting a fire.

"Oh, Brother Li, tell us about it, what kind of treasure is this electric light?"

The other people suddenly came to their senses and asked curiously.

Hearing this, Li Shimin suddenly looked arrogant and smiled proudly.

After Lu Yuan left the Wanjie Purchasing Tower, he began to prepare some materials and equipment for setting up scientific research institutes and schools.

But fortunately, this is the age of Internet information, and instructional videos can be found on the Internet.

He has collected a large number of teaching videos, from primary school to middle school, to university, in all subjects.

However, he still needs to organize and supplement these videos, and it will take some time before he can hand them over.

"Knock knock!"

At this time, there was a sudden knock on the door of the practice room, and Lu Yuan couldn't help but move, spread out, and immediately noticed the situation outside.

I saw Lin Qingyi standing at the door of the practice room and knocked lightly twice.

This is the tacit understanding between Lu Yuan and Lin Qingyi, if there is anything to find him, knock on the door twice, and if there is something urgent, knock three times.

Then, his consciousness felt that in the living room, there was a man in military uniform, this man Lu Yuan was very familiar with, it was Yu Lecheng!

Seeing this, Lu Yuan couldn't help but stare at him, Yu Lecheng came to him in person, there must be something.

Thinking of this, he slowly stood up and opened the door of the practice room.

"Did you bother you? General Yu, who came here last time, has something to look for you, and he seems to be in a hurry. ”

Lin Qingyi couldn't help but breathe a sigh of relief when he saw that Lu Yuan's expression was quite calm, and it should have had no impact on Lu Yuan.

Originally, she didn't want to disturb Lu Yuan, but Yu Lecheng was in a hurry, so she had to knock on the door.

"I see. ”

Lu Yuan smiled slightly and nodded.

Then, Lin Qingyi returned to the room, and Lu Yuan came straight to the living room.

"General Yu!"

Lu Yuan saw Yu Lecheng and shouted with a smile.

"General Lu, you can be regarded as coming out. ”

When Yu Lecheng saw Lu Yuan coming out, he suddenly let out a long breath, and the whole person was much more relaxed.

"What's wrong?"

Lu Yuan was also a little puzzled when he saw Yu Lecheng, who had always been calm, revealing this posture.

"We've found UFOs!"

Yu Lecheng said with a solemn face.
