"Reported to King Yan, the old minister has made preparations. In addition to the necessary disaster food, if you want to obtain cattle, sheep and other livestock, you must work accordingly."

Du Ruhui nodded and replied.

"That's good, Mr. Du, please report the grain and salt we need in Quanyang in the next three months."

"Yes, King Yan."

After Leng Yan gave some instructions, he entered the back hall.

He has many problems now. The entire Quanyang County has a severe drought, and this problem must be solved.

Because the more silver is exchanged, the less silver ore is there, and there is no silver mine in Quanyang, silver has become a non-renewable resource and must be circulated in Quanyang County, so it is best to exchange grain without it.

When I arrived at the back hall, Leng Yan was thinking about how to solve the problem of severe drought.

Asking for rain? These two words just flashed by, and were completely rejected by Leng Yan. Superstitious practices are simply unsatisfactory in Dazhou.

Irrigation? Where to get water?

Suddenly, a flash of Leng Yan's inspiration flashed. Isn't there a Shiyang River in Quanyang County?

Isn’t it enough to just try to attract the river?

But after thinking about it, new problems appeared in front of Leng Yan again.

The dark river seemed to be embedded in a whole huge rock, and it was very difficult to dig a road. Moreover, the Shiyang River was much more on the ground than on both sides of the river, and it took a lot of effort to get the water to the shore.

Um?

Suddenly Leng Yan thought of something left by his ancestors on earth. Although it has rarely been seen in modern times or has lost its practical functions, it does not prevent it from playing a huge role in ancient times.

"Waterwheel!"

It’s just a water truck. As long as the ancient water truck can be brought out, the crisis of this drought can definitely be solved. The more Leng Yan thinks, the brighter his eyes will be.

There is obviously no water truck in this world. If there were any, the people of Quanyang would have used it long ago, so where would there be drought to this point?

Besides, there is really a water truck, how could the area within a radius of three thousand miles of Quanyang be unable to compete?

If only I could build some water trucks, Leng Yan began to think about it.

In ancient China, water wheels were slowly accumulated by generations of people, and they did not gradually mature until Zhuge Liang's hands, but many improvements were still made in later generations.

"Hey, it seems that it is really difficult to summon someone who can build a water truck!"

Leng Yan thought for a while and shook his head helplessly.

His original intention is that there are many opportunities to summon now, and it depends on whether he can summon a carmaker by luck. Now it seems that his hope is very slim.

"Wait, isn't there a redemption system? There are more than 10,000 things there, maybe there will be a water truck."

Thinking of this, Leng Yan hurriedly summoned the summoning system.

Clicking on the redemption column, Leng Yan couldn't help but feel a little headache. The above was full of things, so it was extremely difficult to find a technique.

"System, can't you classify me? This will really blind people!"

He said helplessly to himself,

Unexpectedly, a magical thing happened. After Leng Yan finished speaking, the column of exchange gradually changed. Materials and other types were slowly moved together, and tools, materials, etc. were also slowly gathered together.

"I... can still do this? Then you didn't say it earlier, it made me waste so much time!"

Leng Yan looked at the things he had sorted out on his face and cursed him so much that he was angry.

Especially when he saw the neatly arranged grain, salt and forage, he spent two hours looking for these three things.

Unfortunately, the system ignored Leng Yan's resentment.

"Are there any secrets here? For example, how to build a water truck, etc., if there is one, get it out for me."

In the end, Leng Yan chose to surrender. In fact, he figured it out. The system was very satisfactory. As long as he said, the system would do what it would do, but he didn't know at the time.

Sure enough, as Leng Yan finished speaking, the exchange panel flashed again.

Books of yellow and quaint secrets appeared in front of him, and the first one was the method of making water wheels needed by Leng Yan.

"God, this is too expensive!"

Leng Yan was so happy that he hurriedly looked at the price, but it didn't matter when he saw it, and he was shocked.

I saw that the secret to making a water truck was written below

"The words like "two thousand taels of silver or two thousand reputations."

What can two thousand taels of silver do?

With the exchange system, it is definitely no problem to support the people of Quanyang for a few months. However, the technology for making water trucks now costs 2,000 taels.

"System, can it be cheaper!"

Since I knew that the system could understand what he meant, Leng Yan began to bargain. He didn't know that the food, rice, oil and salt were expensive, but now he could save a little.

"Ding, remind the host that exchange items cannot be bargained. They are consumable items at a time. Only the host can learn it. Join the host and build a water truck. Without the host's permission, even the skilled craftsmen in this world cannot learn and steal it. If the host thinks it is expensive, you can choose one thousand taels to exchange for a water truck directly."

The system did not lower the price this time. Although it did not lower the price, it finally gave the reason why the price could not be lowered.

"Water trucks are so expensive? Then you'd better choose a secret book." Leng Yan refused the good intentions of the system without thinking. After all, technology is the king.

"But, isn't this redeemed technology a patent on the earth? If I don't want to teach technology in this world, then I am the only one who can build a water truck, and others can't learn it?"

Leng Yan thought for a moment and finally knew why a technology sold so expensively.

This is simply a replica of patents, technical protection and exclusive monopoly!

Not only that, if other forces want to build water trucks in the future, they must also obtain his consent. Wouldn't they charge a lot of patent fees at that time?

Thinking of this, Leng Yan no longer hesitated and spent two thousand summoning points to exchange for a secret book for making a water truck.

After redeeming, Leng Yan suddenly felt a warm current flowing into his mind. The steps of creating a water wheel were clearly imprinted in his brain, and he felt that he was now a master of creating a water wheel.

Even the manufacturing methods of tools such as water hangings, water mills, and water mills were deeply imprinted in his mind.

At this moment, the knock on the door sounded, and the person came was Du Ruhui.

"Report to King Yan, the list of essential supplies needed for three months in Quanyang County has been listed. Do you think?"

"Oh, bring it in."

After a while, the door slowly opened, and Du Ruhui walked in with a long list in his hand.

What surprised Du Ruhui was that Leng Yan was also writing something at this moment.

"Old Du, please wait for a moment!"

Leng Yan looked up at Du Ruhui and then said slowly.

As a modern earthling, his brush writing was very ugly. After a while, Leng Yan finished writing and looked at his work, he coughed a few times embarrassedly.

"Old Du, one day later, you go to the county government warehousing to redeem some reserves. Also, please help me find these things, and you can find them as much as you can."

Leng Yan said, handing over a densely packed piece of paper.

Although Leng Yan’s word is ugly, I still see clearly what is written on it.

“All kinds of wood, oil, etc.”

In fact, the most common thing used to make water trucks is wood. In modern times, some water trucks used iron tools. In ancient times, even wedges were made of wood.

Although Du Ruhui didn't know what Leng Yan wanted so much wood to do,

But King Yan said it was an imperial edict. He nodded and then stepped out.

After Du Ruhui walked out, Leng Yan summoned the system panel again, and these secrets had successfully aroused his interest.
