An hour later, the old man Zheng returned to the village with the newly obtained Quyuan plow, which was a prize given by Li Chengqian, otherwise the old man might have ploughed all the wasteland before stopping.

Although the old man has now switched to business, this does not change the essence of his former farmer. Therefore, the old man habitually likes the easy-to-use and convenient farm tool of the Quyuan plow, and even if he doesn't use it when he takes it home, it is a good choice to put it where to look.

The curved plough is very easy to use, the efficiency is at least two to three times that of the previous one, although the speed is not much faster, but in the past, it was necessary to use two ploughing oxen to pull with a straight plough, but now only one is needed.

In this way, one cow is saved, and when the ground is ploughed, it is possible to open double the land at the same time.

Zhang Lao Er was very excited, much more excited than Lao Zheng Tou, and muttered along the way that he had made a fortune, made a fortune, completely ignoring the fact that he was an official (although this 'official' was not in the stream, but it was also an official).

Li Chengqian didn't have so many ideas, as if he had completed a very ordinary thing.

Quyuan plough is a farm tool that has been tested for thousands of years, and has not changed much since the day it was born, even in modern times, it is even used in some remote rural areas.

Compared with the excitement of Zheng Laohan and Zhang Carpenter, Li Chengqian considered whether he could use horses to plow the fields.

There are a lot of horses in the Tang Dynasty, and some old horses retire from the army every year. One horse may not be able to pull the plow, but two will certainly be able to pull it, and it will not be a problem to open four or five times as much land at the same time.

It's just that who to give this credit to is still a question that needs to be considered, and Li Chengqian doesn't want to give it to a guy who has a backbone in the back of his head, so that future generations will say that he is Mr. Dongguo. As for keeping it for himself, Li Chengqian didn't even think about it, and he also didn't want to say that he was the carpenter emperor in the history books.

The broken carriage completed this trip very strongly, carried Li Chengqian back to the imperial city intact, and sent him to Cui Ran, who was waiting a little anxious.

"I've seen Your Highness." Lao Cui, who had drunk eight bowls of 'Zhenguan tea', seemed to have seen a savior, and Li Chengqian's carriage had just stopped, and he rushed up.

Zhenguan tea is the name given by Comrade Lao Li, and the old man seems to like the word Zhenguan very much, no matter what is named with these two words, such as the Zhenguan chair last time.

"Lao Cui is here? Wait, right? Li Chengqian got down from the broken carriage and said as he walked towards the Chongwen Courtyard.

For Cui Ran's wall-top grass, Li Chengqian didn't want him to get too close to him, although the 'Lanruo Temple' was broken, not everyone could enter.

"No, Xiaoxian, oh no, the minister has just arrived." Lao Cui said against his will, not caring about Wu Chen who kept pouting next to him.

Lao Wu is the escort arranged by Li Chengqian to Cui Ran, responsible for the safety of Cui Ran's trip to Shanxi, and of course, more importantly, surveillance. Lao Cui is such a wall grass, Li Chengqian is not at ease to let him go to Shanxi alone, don't be pitted by this goods at that time.

"Let's go, let's go in." Li Chengqian made a gesture of invitation to the room that Cui Ran came out of, and walked in with the 'bald king' first.

When there are outsiders, Li Chengqian is always extra careful, and later generations have seen a lot of things about the dead soldiers and thieves in the TV series, which makes him look like a thief. Who knows if this Cui Ran will not be able to think about it for a while, and play a 'car' trick with himself.

Those who cultivate themselves and govern the country and level the world and achieve great things must pay attention to the details of the matter and consider the pros and cons of the matter as clearly as possible. Therefore, Li Chengqian has always practiced what he practiced, first considering all unfavorable factors when doing things, and putting everything under his control as much as possible before doing it.

Cui Ran put his position very right, and after following Li Chengqian into the house, he sat there silently, neither showing impatience nor showing indifference.

"Lao Cui, this time you went to Shanxi, your task is very heavy, I hope you can understand the stakes and don't be clever." Before leaving, Li Chengqian felt that it was necessary to knock on this wall grass again, so as not to let him spoil his own affairs.

"Your Highness understands, Your Highness can rest assured." Cui Ran replied seriously.

"You may not be able to see the head of the Wang family in the past this time, but it doesn't matter, as long as you explain the stakes of the city and let the Wang family make the right choice." After the beating, Li Chengqian thought that it was necessary to give Cui Ran another reassurance, otherwise who knows if this guy will be dedicated.

Taking a sip of tea, Li Chengqian continued: "Things are done, you will naturally have the benefits of coming back, and it is not impossible to mention the grade again, understand?" ”

"Xia Guan understands, I don't know what specific arrangements His Highness has? Please also advise. ”

Li Chengqian's ability to complete the transfer of his position within two days made Cui Ran fully aware of the energy of His Royal Highness in the ministry. Now that he is not thinking about anything, wholeheartedly doing this for Li Chengqian is the only thought in Cui Ran's heart now.

Knowing the current affairs is the biggest advantage of the wallgrass, as long as you can control his fate, then you should never worry that they will not see the situation clearly and go to the opposite side of you.

"The DPRK and China will soon pass a law to relax the control of salt, and change it to official revenue, commercial transportation, and commercial sales, and the same method will be used for coal. How you take advantage of this message is up to you. Fingers lightly tapped the lid of the tea bowl, and Li Chengqian said slowly.

The salt method that should have appeared a hundred years later Li Chengqian and the eldest grandson Wuji mentioned it, and they also vaguely mentioned it to the old man, and now those old men must be studying it.

A hundred years later, this can only rely on the tax generated by this set of bills to feed all the officials of the Tang Dynasty, and there is no reason why it will fail in the early Tang Dynasty.

Changing official revenue, official transportation, and official sales to official revenue, commercial transportation, and commercial sales can reduce a large number of redundant officials, and can also reduce the nuisance caused to the people during transportation, and can also reduce some cases of personal fraud in official sales, so if nothing else, it is likely to be passed.

Moreover, the profits generated by the commercial movement and commercial sale are enough to make some families excited, so Li Chengqian is not worried that those families will obstruct the passage of this bill.

"Your Highness, Your Highness, can you elaborate on the business fortune and business sale?" Cui Ran sat in the position of the county magistrate for a long time, and almost as soon as Li Chengqian finished speaking, he immediately thought of the huge benefits.

"If you want to sell naturally, you must have a quasi-business license, and this license must be handled by the Ministry of Civil Affairs. Now I can only tell you so much, and the details will naturally be known after the bill is passed. Looking at Cui Ran, whose eyes were flashing, Li Chengqian sneered in his heart.

The family, a group of mercenary guys, is it really that simple? Is it stupid to be Lao Tzu?
