"Because more land has been plowed down, this year's total grain production in Guanzhong alone has increased by 40 percent. Other counties have not yet been counted, but Quyuan plough and waterwheel are mainly only promoted in Guanzhong, and these places should not improve much. If the Quyuan plough and waterwheel are promoted throughout the country, it is possible to double the grain output of our Qin State in the future. Shou Zhukang said excitedly.

The biggest advantage of the curved plough is not to increase the yield per mu, although it can be ploughed deeper, but the increased yield is very little. The biggest advantage is that it is light and fast, and with the same amount of time and less manpower and animal power, more land can be cultivated.

One of the major characteristics of the war years was that the land was vast and sparsely populated, and the Qin State was no exception, especially the two counties of Bashu, Longxi, and the newly established Zhangye County after the annexation of Yueshi, which was full of undeveloped land.

Although the Qin State pardoned many criminals and moved sons-in-law, merchants, including their parents and grandparents, went to these places, but they still could not change this phenomenon.

"Then immediately arrange personnel to promote. Enough quyuan ploughs have been built in the treasury, and all of them have been leased to the head of Qian. In addition, local officials were ordered to organize personnel to build waterwheels and lease them to Qianshou for use. As for the rent...... Levy from grain production for the next five years. Qin Wangji thought for a moment and did not choose to collect rent directly.

Although the imperial court is short of money, the head of Qiantou is even more short of money, and they must be relieved. Moreover, it is easier for everyone to use it first, so that everyone can see the role of Quyuan plough and waterwheel and then collect rent, so as to reduce the contradiction between the leaders of the Qianqian and the imperial court.

"The king is wise." Shou Zhu leaned over and said.

"Is there any news about the Far West?" Qin Wangji looked at Lu Buwei again.

"Your Majesty, the Far West is far away, and there is no news yet." Lu Buwei shook his head.

Qin Wangji was a little disappointed, the reason why he named the new county Zhangye County was to hope to be able to open the arms of Zhang Guo, and now it seems that this arm is difficult to open.

It's been almost a year and there has been no news. Even if he came back one day with news, what use would it be to the Qin State?

What the Qin State needs is an enemy, an enemy that can just be conquered, if it takes two or three years to go back and forth, even if it knows that there is such an enemy, how can the Qin State pass?

"What about Yue Guo?" Qin Wangji asked again.

"The king of Yue is still leviing Baiyue." Fan Ju said.

The country is close to the East China Sea, the territory is mountainous and river-like, and the shipbuilding industry is developed.

In the past, because of the hot weather, the fish were always broken and could not be stored, so the country rarely organized people to go to sea to fish.

Now with Zhao Guo's endless supply of salt, it is white and cheap, and the fish is directly salted and dried after being hit, and it is not a problem to store it for a few months, and it can be used as military food, and it is more nutritious than food, and even the soldiers are much stronger.

The disadvantage is that I want to vomit when I see the fish after eating too much, and my mouth is full of fishy smell.

But compared to not having enough to eat, these are not problems.

Moreover, there are so many fish in the sea that it is unimaginable, no matter how you fight, there are few people in the Yue country, and the soldiers were only a few thousand at the beginning, but now it has only expanded to 15,000, since it was able to pickle and dry the dried salted fish, the Yue country has been fighting for almost a year, and has never worried about military rations.

"The widow heard that the king of Yue has a daughter, and she has good looks and talents. Chu, the grandson of the widow king, happened to have not yet married a wife, so he sent a messenger to ask the king of Yue's opinion. Qin Wangji said, now the only place where Qin can break the situation is Yueguo.

"Why don't you go there yourself?" Fan Ju's heart moved, and he spoke.

For such a long time, it has always been Lü Buwei who has liaised with the Yue State on behalf of the Qin State, and if the Yue State is successfully restored in the future, Lü Buwei's status will inevitably rise through this, and even threaten his status.

Of course, Fan Ju would definitely not destroy the relationship between Qin and Yue in order to deal with Lü Buwei, and now Qin needs Yue.

But with a higher status and means, it is not difficult to steal Lü Buwei's credit on his own head and make Yue Guo grateful to himself.

"The widow can't do without Xiangguo, Xiangguo still recommends a person." Qin Wangji said.

"The minister elected the long history Wang Ji." Fan Ju did not hesitate to say a name.

When Lü Buwei heard this, he stepped back on one of his legs.

Although Wang Ji is Fan Ju's person, he is a confessor himself, and he is responsible for envoys to various countries, which is very suitable for both public and private affairs, although he wants to stop it, but there is no reason to stop it.

If it is said blindly, it will cause the dissatisfaction of King Qin.

"Then Wang Ji will be in charge of this matter." Qin Wangji didn't think much about it, so he responded.

"Obey." Wang Ji took a step forward, leaned over and said.

"If it's okay, let's disperse." Qin Wangji waved his hand and said, "If you catch an assassin, notify the widow immediately." ”

In fact, the loss of Qin State was not much in this matter, those books were just copied, and they were not alone, so it took some manpower and material resources, so after so long, Qin Wangji also calmed down.

Of course, this does not mean that he will let go of the assassin, if it is not for his lack of strength, even Zhao Guo will not let go.

However, Gai Nie didn't have any pressure at all now, and when the Qin State sent people to arrest him, he was already out of the city.

Moreover, as a powerhouse of the transcendent realm, Qin Guo did not catch him in the first place, and it was impossible to think about catching him after he escaped.

As early as half a month ago, he had already felt Xianyang, and he had been looking for opportunities during this time.

The Qin State Library Pavilion is not far from the palace, and there are Fei Lian troops patrolling back and forth every day, and the defense is very tight, and there are transcendent realm warriors in the palace.

Under normal circumstances, it would have been impossible for him to sneak into the library and set it on fire, and he would have been caught before he could enter.

After wandering back in Xianyang City for half a month, he finally found an opportunity.

Qin Wangji invited the selected scholars from all over the country to a banquet, and after the banquet, he personally sent these scholars out of the city, and the Chinese military ministers also followed Qin Wangji to send off the scholars.

Half of the Fei Lian army was divided to protect Qin Wangji, and the defensive strength of the library pavilion was greatly reduced.

Gai Nie took the opportunity to sneak into the library pavilion, killed people, set fires, and with a wave of his sleeves, the internal qi stirred the wind, expanding the fire, and then burned away, the whole process took less than a minute.

The entire library is all wooden, and although it has been fireproofed, there is no way to really prevent it, and after the fire burns, it can't be suppressed completely.

After leaving, Gai Nie found a place to stare at the library, and when he saw the fire spread out the window, he turned and left.

When Qin Wangji received the news and rushed back, everything was a foregone conclusion, except for some of the books on the first floor, the second and third floors were all burned, fortunately, the first layer had the most books.

Early the next morning, Gai Nie saw a notice outside the city that he wanted him, but there was no name or portrait, just a 'suspicious person'. And from passers-by, I learned that most of the library was burned down.

"Successfully complete the task and return to Zhao. Let's go to Yuci first and have a drink with the old brothers from before. Gai Nie thought to himself, and strode towards the northeast.
