"Zhao Zhonglang, the king has summoned you to meet you."

When the confessor came to the Zhonglang official office to convey the order of Qin Wangzheng, everyone in the room was stunned.

Yang Xiong and the others all looked at Zhao Tuo with a worried face.

Princess Yin Yan often took away Zhao Tuo, which is not a secret in the Lang system, and everyone can vaguely guess something. Now that the king has sent someone to summon Zhao Tuo to go, I am afraid that it will be more than lucky.

Li You was also in the house, and took advantage of the situation to urge: "Zhao Tuo, the king summons you, don't delay, don't go quickly."

"Yui."

Zhao Tuo got up with a bitter face and followed the confessor out of the door.

Seeing the kid walk out, Li You had a smile on his face.

Zhao Tuo has walked the forbidden road many times, but none of them have been as nervous as this.

He wasn't sure what Qin Wangzheng's attitude was to this matter.

But nervousness is nervousness, and Zhao Tuo is not very afraid.

Because Qin Wangzheng's intention to marry the Li family is just a rumor today, not a foregone conclusion, and Qin Wangzheng has not publicly made promises or agreements.

Even rumored that King Qin was only "intentional", not ironclad.

In this case, it is unlikely that he will severely punish Zhao Tuo for this matter, and at most reprimand.

Moreover, Zhao Tuo believed that he was still very useful to the Qin State, and if Qin Wangzheng was angry, he could throw out the method of making fertilizer, so as to regain the favor of Qin Wangzheng.

"This one-on-one summoning is a good opportunity to speak."

Thinking of this, Zhao Tuo put his mind at ease again.

When he walked into the palace where Qin Wangzheng was, his demeanor was already calm and calm.

The hall was quiet, only the candle flame was flickering, Qin Wangzheng sat on the couch, staring at Zhao Tuo with burning eyes.

Zhao Tuo felt a little numb, because he felt a kind of fiery heat in the eyes of this King of Qin, not the annoyance that he had originally guessed.

This situation does not seem to be the same as expected.

"Minister Zhao Tuo, meet the king."

Zhao Tuo saluted respectfully.

"Hmm. Zhao Tuo, I heard that you have a way to increase the yield per mu of farmland?"

Qin Wangzheng went straight to the point and did not dwell on lies.

Zhao Tuo was stunned when he heard this, but he immediately reacted and arched his hand: "However, this method was obtained by the minister when he was in Zhao State......

"The widow just wants to know if this method is really effective and can it be extended to all parts of the Qin State?"

Qin Wangzheng impatiently interrupted Zhao Tuo's words, he just wanted to know the effect.

"Yes, the minister has already experimented in the farmland in Chaoyang last year, and the 100 mu of millet planted using this method will increase the yield per mu by about one stone compared to the farmland without this method, and this is only the lower field, if it is used in the fertile upper field, it may be able to increase the yield a little more."

Qin Wangzheng's eyes lit up, Zhao Tuo, this kid has always been smart, since he dares to say so, he must not be making it up.

"What is the way to increase food production?"

"This method is called manure."

Zhao Tuo's voice was quiet, although Qin Wangzheng's initiative to ask made him a little surprised, but Zhao Tuo, who had already filled his belly, did not panic at all. The principle, steps, effect and difficulty of implementing the whole method of manure are clearly explained.

"Fresh manure cannot release all the fertility and needs to be accumulated......

….

Qin Wangzheng pondered Zhao Tuo's words in his mouth, he was not a royal son who had been clothed and fed since he was a child, on the contrary, he had experienced a lot of hardships in Zhao when he was a teenager, and even encountered the risk of death.

Qin Wangzheng is not taboo about the filth mentioned by Zhao Tuo, not to mention that these things can make his country stronger.

"There is a method of applying manure to the people, and this method is only to accumulate filth for a period of time on the basis of it, which is really simple and easy to do."

The more Qin Wangzheng thought about it, the more excited he became, if Zhao Tuo proposed a method that was difficult to operate, or extremely demanding and difficult to implement. He may be happy, but he will never be excited.

But Zhao Tuo's method of manure is really too simple

Single, every farmer can easily do it, and the materials used can be found everywhere, human and animal manure, dead branches and leaves......

There is no cost at all for the government to implement the method of manure, and there is no greater expenditure except for sending people to the villages to teach this method, which is far more cost-effective than repairing water conservancy projects and the like.

And if the effect is really as Zhao Tuo said, it can increase by one stone per mu, no, even if the yield per mu can only increase by half a stone, it can also make the national strength of the entire Qin State soar.

The Chu lands occupied by Guanzhong, Bashu, and Qin, plus the newly conquered Han, Zhao, and Yan regions.

There are tens of millions of acres of farmland, how much new grain should he have in the Qin State in a year?

Such a wonderful method is even more useful than the canal that Zheng Guo built in Guanzhong.

With more food, the Qin leader will be able to reproduce more people, and he will be able to recruit more troops to conquer a wider territory!

Qin Wangzheng suppressed his excitement, stared at Zhao Tuo and said, "I have also lived in Handan for a long time, why have I never heard of Zhao Di having this kind of farming technique?"

Zhao Tuo was not in a hurry, he had already prepared for this.

"King Yu, this method is indeed not used by the Zhao people to farm the land, but from the farmer's family."

Farm?

Qin Wangzheng was stunned, slightly surprised by this answer.

According to Zhao Tuo's explanation, when he was young, his family was prosperous and he had a small fief in Zhao.

More than a dozen people wearing cloth clothes and linen shoes came to Zhao Tuo's fiefdom, thirsty for a small piece of land to cultivate, and promised to pay taxes on time.

At that time, Zhao Guo was at war with Qin and Yan, and the Zhao people suffered a lot of losses, with more fields and less land, and there was a shortage of cultivators, so they naturally agreed to this kind of thing.

Those people settled down on the fiefdom of Zhao Tuo's family and cultivated seriously.

Zhao Tuo's curiosity was at that time, and he often wandered in the countryside, and saw that those people's farming methods were different from those of Zhao people, so he humbly asked for advice, and those people taught Zhao Tuo a lot of special agricultural knowledge, including this method of manure.

"At that time, those peasant heirlooms had just discovered the magic of the manure method, and they were still in the trial stage, so it didn't spread. Then the minister's father was killed by Guo Kai, and the minister could only flee in embarrassment, and the minister no longer knew the whereabouts of those peasant heirs."

When Zhao Tuo said this, two tears were squeezed out of his eyes, as if he was in the sadness of a broken family.

Qin Wangzheng bowed slightly.

Farmer, he's heard.

It is also one of the hundred schools of thought, and its representative figure is Xu Xing, a contemporary of Mencius.

These peasant people took the Shennong clan in ancient times as their ancestors, advocating persuasion to cultivate mulberry and provide enough food and clothing. They did not participate in political disputes, but immersed themselves in the fields, and developed many agricultural techniques.

….

The method of manure is a cultivation technique that has been studied by farmers.

There is nothing flawed in this statement.

"Well, the widow will let Zhisu Neishi find you, and then you will tell him this method. This matter will be tested in Guanzhong first, and if it proves that this method is effective when the autumn harvest is in the autumn next year, it will be extended to the entire Qin State."

"If it is done, the widow will not be stingy with your reward."

"King Xie."

Zhao Tuo showed gratitude and respectfully retreated.

watched Zhao Tuo's back disappear outside the door.

The corners of Qin Wangzheng's mouth turned up slightly.

Farm.

Plus the previous male loser.

This Zhao Tuo has a lot of secrets.

But Qin Wangzheng didn't care.

Just as he didn't care if his ministers were from the Six Kingdoms, he didn't care where the methods and wisdom of these people came from.

As long as it is useful to the Qin State and loyal to him Qin Wangzheng, then it should be used and reused!

Qin Wangzheng's excitement because of the method of manure gradually calmed down.

He reflected on the events of the day, and a strange smile appeared on his face.

"What a concubine, even the widow was teased by you."

……

Zhao Tuo

When I walked outside the temple, I was refreshed.

He originally thought that he would encounter an angry rebuke from an old father today, but he didn't expect it to become a good opportunity for him to talk to Qin Wangzheng about the method of fattening.

The method of manure has been tested horizontally, and it will definitely be useful, although the effect is slow, but as long as it is harvested next autumn, it will be a great credit for stability.

"With such a great achievement, you can go up a level."

Zhao Tuo was not in a hurry at all, the method of manure can greatly enhance the national strength, and with the temperament of Qin Wangzheng, he will definitely be promoted to a knighthood.

This kind of opportunity for steady upgrading should naturally be reserved for a higher level to enjoy in order to maximize the benefits.

"It's just that the king didn't mention the princess, and he also knew the method of manure in advance."

Zhao Tuo thought about it in his heart, because he didn't have the opportunity to talk about Qin Wangzheng before, he mentioned this matter a little bit when telling a story to Yingyin Yan, hoping that this princess could help him find an opportunity.

But Ying Yinyan has never responded, as if she is not interested in this kind of thing, and after a long time, Zhao Tuo gave up.

Unexpectedly, the other party did not listen, but wanted to save this matter for the right time.

Zhao Tuo felt something in his heart and looked back at the corner of the palace.

A girl in a purple skirt was standing under the eaves, and when she saw Zhao Tuo, she showed a playful smile.

Zhao Tuo also responded with a smile.

She's smart.
