Three Kingdoms: At the beginning, Diao Chan came to the door with her daughter.

Outside the pavilion.

Next to the ancient road.

Han Yi instructed Yang Zaixing: "Zaixing, I will hand over my father-in-law to you and Yanqing, be sure to escort him to Chang'an, and you must not go out halfway through!"

Yang Zaixing clenched his fists and arched his hands: "Don't worry, even if we rest at night, we will protect everyone Cai every step of the way, unless we wait for the battle to die, we will never let everyone Cai have anything to do!"

"What doesn't die in battle. "

"Don't say such discouraged words!".

Han Yi patted Yang Zaixing's shoulder and said with great certainty: "I believe that the person who can kill the two of you in this world has not yet been born, I will wait for you to come back!"

"Don't worry!".

Yang Zaixing gave up again.

"Hmm!".

Han Yi nodded heavily, and then turned back to Cai Yong.

At this moment, Cai Yan handed the letter in his hand to Cai Yong: "Father, after you return to Chang'an, give this letter to Lord Situ Wang, this is her daughter Diao Chan's family letter." "

"Well, good!".

Cai Yong put the letter away and instructed: "You, too, write back more letters to let your father know your situation, if Jiaheng dares to treat you badly, Dad will definitely kill Mount Tai and make the decision for you!"

"Dad~~".

"Don't worry, the husband will be good to Yan'er. "

Cai Yan glanced at Han Yi, those eyes were full of love.

"Uncle Yue, rest assured. "

Han Yi also hurriedly said: "Yan'er is my wife, I will naturally love her, for the rest of my life, forever!"

Cai Yong smiled, nodded, and lowered his voice: "What's the use of talking? "

"Dad~~~~".

Suddenly, Cai Yan blushed with shame.

"Don't worry!".

Han Yi was bold and responded with a smile: "This matter has been put on the agenda, and you will be able to hold your grandson next year!"

"Haha!".

Cai Yong looked up to the sky and laughed: "Okay, you kid, you have to talk about it, I can wait!".

Han Yi: "Don't worry! The husband has made a word, and the horse is difficult to chase!".

Cai Yan hurriedly tugged at Han Yi's sleeve: "Husband, what do you say, are you ashamed!"

Han Yi smiled indifferently: "What's so shameful about this, human nature, don't you want a baby?"

"Haha!".

"I've got to go, so I won't bother you flirting. "

Cai Yong pinched a lock of beard under his chin.

Seeing that the two had a good relationship, he was completely relieved.

"Father, go slowly!".

Cai Yan hurriedly helped his father into the car and beckoned: "Father, if you can't stay in Chang'an, you must come back to Mount Tai, don't hold on, you know?"

"Got it!".

Cai Yong waved his hand, followed the carriage, and slowly left.

The moment he lowered the curtain.

Tears in the corners of the eyes.

Finally, it still can't stop dripping.

*****

At the same time.

The harvest of Mount Tai and the amazing news of the yield per mu are also spreading.

Like a plague, it quickly spread throughout the Yanzhou Continent and spread to Jiqing and Xuyu!

East County.

Taishou House.

Cao Cao frowned, and said incredulously: "What? Taishan County's yield per mu this year has at least doubled? How is this possible!".

Xun Yu took a deep breath: "Although the information may be wrong, one thing is inevitable, Taishan's grain harvest this year is indeed very good, and it should be far better than in previous years!"

"Conservative estimate!".

Speaking of this, Xun Yu paused for a long time before he spoke: "It should not be less than four stones per mu! After all, their high-barrel waterwheel can expand the irrigation area, which is equivalent to more than 100,000 mu of paddy fields in plain white!"

"Lord!".

"The yield of this paddy field is about three stones, plus all kinds of messy things, the yield per mu of Taishan County reaches more than four stones, it should not be a problem!".

Four stones!

Four stones per mu!

Cao Cao naturally understood what this meant.

In comparison, the average yield per mu in Dongjun is only about two stones.

You must know that this is still under the premise that the river flows through and the irrigation is sufficient, once it encounters a disaster year, it is estimated that the grain output will be at least halved, or even reduced by half!

But what about Taishan County?

Not only do they have a large area of cultivated land, but they also have an amazing yield per mu, and one year of work is equal to two years of work for others.

In this way, even if there is a disaster year or something, people have enough food and grass to survive safely!

Sour!

Cao Cao is really sour!

The improvement of agricultural tools has such an effect.

Not only can the work efficiency be greatly improved, but also the production can be increased!

This Nima!

Cao Cao immediately ordered: "Wen Ruo! I don't care what method you use, but I must also move Taishan's improved farm tools to our Dongjun before next year's spring ploughing!"

Move?

To put it lightly!

Taishan County's strict defense, even now, Xun Yu has not been able to break through.

This rhythm ......

The other party is obviously prepared!

How can you tell you to move, and you can move away?

Xun Yu was helpless.

This Nima, it's so hard!
