The occurrence of the Tang Yunbi incident changed many of Tang Wenyuan's plans.

Originally, the recruited builders were intended to be used as an army, but now that they have an army in their hands, these builders can really be used as builders.

After electing the management of the constructors, Tang Wenyuan personally gave a lecture to them.

Time was of the essence, and it was naturally impossible to teach them all the advanced architectural knowledge, so they only selected the parts of the city wall that were to be built.

Digging foundation grooves, laying foundations, fixing templates, how to match steel bars, and how to tie them.

How to mix concrete, how to use it......

All the architectural knowledge related to the construction of the city wall was written into textbooks by Tang Wenyuan one by one, and everything was detailed.

As for the question of pay-off and level, the craftsmen of the Wen Dynasty had their own methods. Otherwise, how could this boxy Forbidden City be built?

In addition to training, there are a lot of things to be busy these days.

Everyone in Jinyiwei has to be vaccinated against smallpox, this is Tang Wenyuan's cronies, don't worry about what goes wrong, the main reason is that you can earn points.

In terms of food, Tang Wenyuan also began to prepare.

The wealthy merchants in the capital left and vacated a lot of land, plus what they bought before and what Su Jingsheng contributed to him, a total of 30,000 acres of land.

Tang Wenyuan planned to plant 10,000 acres of corn and 20,000 acres of wheat, but potatoes were too troublesome and chose to give up for the time being. As for peppers, tomatoes, etc., just grow them in the palace and eat them yourself.

Now everything has to be prepared for war.

According to the system, these seeds are ripe in March and can be harvested twice in six months.

Since it is high-quality corn and wheat, plus fertilizer, there is no problem with a yield of 1,000 catties per mu.

30,000 acres of land, harvested twice, 6 million catties of grain.

You heard it right, it's six million catties of grain, after all, this is a high-quality seed, and the yield per mu is not a problem.

If it is planted with wheat seeds from the Wen Dynasty, 30,000 acres of land, and if it is harvested once, it will only be about 800,000 catties of grain.

In ancient times, the yield of wheat per mu was already very good, and the yield per mu during the Warring States period was only more than 100 catties.

What is the concept of 800,000 catties of grain? The army of 100,000 was eaten in ten days...... This is still the case of eating tightly. So six million catties of grain just sounds bluffing, and when the time comes, Tang Wenyuan will have to take care of the food of the entire Chang'an City, and six million catties is actually a pitiful ......

Tang Wenyuan originally wanted the landlords in the capital to plant all the land they owned into high-quality seeds, but the points were not enough. If you spend all your points on food, you won't have to build the city walls.

The task of farming was assigned to the Duke of Protector, and he asked the soldiers to farm with experienced farmers. In this way, labor costs are reduced.

And the 30,000 soldiers of the protector will be stationed around these 30,000 acres of fields in the future, and the main purpose is, of course, to protect the farmland.

After the harvest twice, the soldiers were to withdraw into Chang'an City.

Most of the farmland was outside the city, and the newly built walls could not cover the farmland, so they had to give up after six months.

In terms of farm tools, Tang Wenyuan asked people to produce on the one hand, and on the other hand, they asked people to borrow from the landlord's house, mainly to borrow.

Now there is a need for manpower in all aspects, and workers have to save money.

The advantage of being an emperor is that you only need to do most things, and the people below will do their best to help you do it.

In normal times, the ministers may still have a little bit of cheating and trickery, but now the situation is different.

In addition, Tang Wenyuan is very diligent, so he will go out here to run around when he has nothing to do, take a look at where to see, and supervise the progress of various things.

Today, Tang Wenyuan just came back from the field, sweating profusely, and before he could sit down and drink saliva, Su Jingsheng came to him.

"Your Majesty, the military department has run away." (The one who committed suicide in front was the Ministry of Rites Shangshuha, who was written incorrectly at the time and has been revised.) ）

Tang Wenyuan's brows furrowed, "Ran away?" ”

"With his family, he pulled the belongings of the three carriages, and escaped from the south gate last night."

Tang Wenyuan sighed softly, "Let's run away, do you have any recommended candidates?" ”

"Chu Hanyi."

"It's just him, you let him take office immediately, and after taking office, count all the soldiers under the jurisdiction of the Ministry of War and hand them over to me."

"Wechen takes orders."

"By the way, Su Aiqing, how many arrows do we have now?"

"More than 100,000, most of the arrows are at the border pass, and Your Majesty can send some of them back if you need to."

"No, leave it to them to defend the city, and drag it out for as long as they can. Who has more wood in the nearest vassal king? ”

"King Ping, Tang Yunke, he is in Rongcheng in the northeast, close to 10,000 acres of forests."

"How long does it take to go back and forth to get timber from him?"

"Twenty days is enough."

"Recently, the grain tax has just been collected, and you send 10,000 people to carry 400,000 catties of grain to King Ping to exchange for wood."

Su Jingsheng was a little incomprehensible, "Your Majesty, it's just wood, do you still need to exchange food for it?" Ask him directly. Now is the time when there is a shortage of food, take 400,000 grain to exchange for wood, what will happen in six months? ”

"These 400,000 catties of grain include the consumption of the soldiers who come and go, and there are still 200,000 catties in the hands of King Ping. If you ask him for it, he may not be willing to give it willingly. You tell you to cut as much wood as you can, and if the carriage is not enough, ask King Ping to borrow as much as he is willing to borrow, and we will pull as much as we want. As for the food problem, Su Aiqing doesn't have to worry, didn't I grow 30,000 mu of grain, all of which yield 1,000 catties per mu, and it will be enough to eat when the time comes. ”

Su Jingsheng looked at Tang Wenyuan in surprise, but didn't say anything. He is used to listening to Tang Wenyuan's big words, as long as you have the materials to repair the city wall, there is no problem in terms of time.

But the grain is different, the best wheat in the Wen Dynasty has a yield of only 200 catties per mu, you just blow a thousand catties per mu and tease me......

However, on the issue of food, Su Jingsheng also has a back hand, and he has already arranged for Luocheng to start hoarding food. Six months later, transporting the grain over can also help Tang Wenyuan last for a while.

The reason why Tang Wenyuan asked for wood was to make arrows, and the biggest consumption in the defense of the city was arrows, not to mention one million arrows, even if it was two million arrows, it might not be enough.

Although the system mall has updated the building template, the wood used for the building template is plywood wood, and it cannot be used as an arrow at all. Most of the timber in Chang'an City is used to make wooden scaffolding, and the cost of such a huge project is huge, so it must be prepared in advance.

And the reason why Tang Wenyuan gave Tang Yunke food was that he was worried that Tang Yunbi would unite with other vassal kings to attack him together. Although Su Jingsheng and Su Qinghan both analyzed that other vassal kings would only watch from the sidelines, who could say for sure that there was such a thing as a war?
