The faces of King Han and King Wei changed instantly, how could a pampered monarch like them stand the murderous aura that Zhao Kuo came out of fighting on the battlefield.

The whole person suddenly fell into a sea of blood, and there was blood and dead corpses everywhere, constantly approaching them.

"That'...... That's according to King Zhao. King Han clasped his hands, trembled all over, and said tremblingly.

Storm Kite and Zhang Ping sighed in their hearts, their faces were lonely, and the faces of Lian Po Tiandan and the others were full of smiles.

Sometimes, not only the minister can earn face for the monarch, but the monarch can also earn face for the minister.

Zhao Kuo sneered in his heart.

Talking about the conditions, it is really not okay to blindly be gentle.

Only the kindness of the strong is mercy.

The kindness of the weak is as worthless as the breasts of a fat woman.

King Wei's face was gloomy, King Han had already agreed, and he had no way to refuse anymore.

"What does the second brother think?" King Wei looked at Wei Wuji, who he hoped would refuse.

"The younger brother is willing to take Wei as a hostage." After a few breaths, Wei Wuji clenched his fists and said.

It's not because he is not reused in Wei, nor because of his personal relationship with Zhao Kuo, but because Wei and Zhao really need a bridge of communication, and this bridge can only be done by him.

"Well, this king also agreed." King Wei nodded helplessly.

"Well, since the two kings have agreed, the king will not hide it. I, Zhao Guo, recently invented the Quyuan plow, which is used to replace the unyun, which is not only labor-saving, but can be pulled with only one ox, and the plough is deeper, faster, and more than twice as efficient as the unyun. ”

"In addition, I Zhao Guo also invented a waterwheel, which can automatically irrigate both to the highlands, which greatly saves manpower and material resources. With a waterwheel, a dry field can become a paddy field, a lower field can become a middle field, and a middle field can become an upper field. ”

"Adhering to the principle of mutual help and mutual assistance between the three Jin Dynasty, in order to promote the common development of the Three Jin Dynasty and realize the common prosperity of the Three Jin Dynasty, this king is willing to send Quyuan plow and waterwheel technology to Wei and South Korea."

Zhao Kuoyi said solemnly.

"Really?" King Wei and King Han's eyes became brighter and brighter, and they said excitedly.

Even the most mediocre monarch knows the importance of grain, why did Shang Ying emphasize agriculture and suppress commerce? Isn't it just to tie people to the land?

They don't believe what Zhao Kuo said about turning dry fields into paddy fields, lower fields into middle fields, and middle fields into upper fields, but even if it is only increased by 10 percent, it will be a big profit for the two countries.

"Yes, the two kings can send craftsmen to my Zhao Kingdom to learn how to make Quyuan plows and waterwheels, and this king can also send a few finished products to the two countries. However, there are two conditions for this king......" Zhao Kuo said.

"On what terms?" King Wei and King Han hurriedly asked.

As long as the two countries are not annexed to Zhao, even if it is a temporary subjugation, they can agree.

No one was born to want to be a faint king, and they also wanted to make Wei and Korea strong, but in the end they were crushed by reality.

Now if they have the chance, they're willing to give it a go!

"The first condition is that within five years of Korea and Wei, fifty percent of the increased grain output will go to my Zhao State. The second condition is that in the next five years, Korea and Wei will provide 10,000 catties of iron for our Zhao State every year. Zhao Kuo said.

There are many iron ores in China, but most of them have a low proportion of iron and are in a deep layer, which is not only difficult to mine, but also difficult to smelt, resulting in a shortage of iron in China since ancient times.

But Nanyang is an exception, not only the iron ore is of high quality, the iron content is high, after a smelting, it is the best iron, and most of the iron ore is on the surface, and the difficulty of mining is low.

South Korea originally relied on the iron ore in Nanyang to build strong crossbows, form strong crossbow soldiers, and make a fortune.

Later, Nanyang was occupied by the Qin State, and the crossbowmen also declined.

"We can agree to the first condition, but the second condition King Zhao is probably a little difficult for a strong man, after all, we have not seen the Quyuan plow and waterwheel that King Zhao said, and Zhao Guo has only just made it, how can we guarantee that we can increase the production of so much grain? If we don't have so much, won't we lose money? Han Wang said.

With South Korea's strength, it can't smelt much iron in a year, and if the value of the increased grain output cannot exceed 20,000 catties of iron, it will be a loss, after all, half of the increased grain will be distributed to Zhao Guo.

"This king said that it was fifty percent, but when the time comes, how much will South Korea increase its production and how much grain will be shipped to Zhao State, King Han should know in his heart. The 10,000 catties of pig iron that the king said was just to get fifty percent of the grain.

As for the increase in production that King Han is worried about, this king can promise the two of them, if the total grain output of the two countries cannot be increased by 50% next year, my Zhao State can not need this 10,000 catties of pig iron. Zhao Kuo said.

Don't think about it, no matter how much South Korea and Wei increase their production at that time, they will definitely give Zhao less grain.

It is impossible for Zhao Guo to check one acre at a time, as long as it is not too much, he can only choose to acquiesce.

This 10,000 catties of iron is to make up for this part of the grain.

"In addition, the stirrup and saddle technology, and the catapult technology, this king was unconditionally given to Wei and Korea at the beginning, and how useful these three things are, the monarchs of the two countries should know in their hearts." Zhao Kuo said in a deep voice.

At first, he gave the stirrups and saddles to Wei and Korea without any reservations, and as a result, neither country has established a cavalry formation.

The Qin State stole it, and in less than two months, all the cavalry were equipped with stirrups and saddles.

Zhao Kuo can only say that there is a gap between countries.

King Han was silent for a moment and gave a salute: "Thank you King Zhao for your help, the widow agreed." ”

"I, Wei Guo, also agreed." King Wei also said.

"One last thing, I, the Zhao State, am willing to help the Wei State and Korea form a formed cavalry, with a number of no less than five thousand." Zhao Kuo said.

"Is King Zhao serious?" King Wei and King Han couldn't sit still at this moment, their eyes widened, and the others also looked at Zhao Kuo in disbelief.

The cavalry of Zhao State is unparalleled in the world.

This is a fact recognized by the seven countries.

Zhao Feiqi is the only cavalry army soul legion in the world.

It can be said that cavalry is the foundation of Zhao's strength.

It's too late for a normal monarch to hide the training methods of cavalry, how can it be spread?

If he hadn't known Zhao Kuo's past achievements, I'm afraid that the ministers of Wei and South Korea would have regarded Zhao Kuo as a big fool long ago.

"Oh no, my lord!" Lian Po and Tian Dan hurriedly dissuaded, looking panicked and unexpected.

In fact, Zhao Kuo had already discussed it with them yesterday, and now he was just making a show for King Wei and King Han.

Zhao Kuo stretched out his hand, signaling that the generals didn't need to be dissuaded anymore, and then nodded, "Seriously." ”

The stirrup and saddle had spread, and with these two things, the difficulty of cavalry training was greatly reduced, and even without the help of Zhao State, Wei State and Korea would be able to train cavalry sooner or later.

Rather than this, it is better for Zhao to personally help Wei and Korea train cavalry, and with cavalry, the two countries will have the strength to confront Qin.

Can't all the cavalry facing Qin in the future let Zhao Guo rush to the front, and Wei and Korea hide behind, right?

And Zhao Guo can also take this opportunity in exchange for some benefits.
