When the princes of each family were fighting, they would transfer an archer of thousands of people. These archers did not shoot the enemy, but supervise the battle. If they dared to retreat, they would shoot arrows. This was called a supervising team.

The Xuzhou Army also has a prepared supervision team, but it is not easy to use it unless it is a rush.

Feng Xiong next to him said, "You lord doesn't look very satisfied?"

Lu Bu shook his head: "I feel that we should study more advanced methods of siege, rather than relying on consuming lives to climb walls and siege cities."

"Now, we are sieging the city like this, we can build at most some catapults." Feng Xiong scratched his head.

Lu Bu supervised the training of the soldiers. He returned to the Central Army during lunch and lay alone on the chair in the study to think about things.

I took a paper and pen to write down the magic weapon for siege, a small hand-held crossbow. It uses a composite arm of steel plate and mulberry wood. The small crossbow is not large, with a maximum range of 30 meters and an effective range of 20 meters. It can fire ten chopstick arrows in a row, but its penetration is not strong, but its firepower is relatively strong, so it is still possible to suppress the firepower from the city wall upwards. After all, the city wall is only about ten meters high.

The so-called chopstick arrow means that the size of the arrow is similar to that of the chopsticks, with an iron tip on the front.

Therefore, there must be a thousand crossbow soldiers, so that they can suppress the enemy after attacking the city wall and prevent counterattack.

In addition, the essential artifacts for time travelers, black gunpowder, cement, and glass.

The last two can be redeemed from the system, and the price is very cheap, so there is no need to produce them yourself in the short term. Although the first one cannot be redeemed, it is easy to make.

Sulfur, saltpeter, charcoal powder, blend it and it's done.

It is precisely because this is too simple that Lu Bu has never made it. Because the production process is too simple, it is easy to make it. Lu Bu doesn't want to make it when he has no advantage.

I spent money to buy materials first, mainly sulfur and saltpeter. As for charcoal powder, I should forget it, and I can burn as much as I need.

When the time is right, you will create the formula and then spread it without any advantage.

What we need to focus on now is the crossbow of the wheelbarrow of the Liao Hua Pioneer Army. This crossbow has a simple structure, which is like a large crossbow installed on the top of the wheelbarrow.

It uses a large arrow more than one meter long, with a dovetail-shaped arrow, and the barbs are very strong, similar to a mop rod.

The single crossbow has a range of 150 meters and can take arrows alone. The double crossbow is also relatively light. The two of them use a winch to quickly launch arrows and shoot out with a whizz.

It started manufacturing during the military campaign in Xuzhou. In the past six months, two hundred single-bow crossbows and one hundred double-bow crossbows were built.

This is the sorrow of handicrafts. If there is mechanization, so many will be built in a few days.

According to Lu Bu's idea, at least 500 crossbows were used to attack the city, and arrows were as rained as the city, suppressing the enemy's momentum and morale before attacking the city.

Some cities are still rammed earth, and swallowtail arrows can be stuck on the city wall as a means of climbing.

Lu Bu came to the door and shouted to Xu Shitou: "Call the chief minister to be the king."

"yes."

After a while, Wang Heng jogged over, and for half of the time, Lu Bu didn't look for him.

"Master, what's the matter?"

"A big thing, a very important thing. Nitrogen and sulfur need to be purchased in large quantities, the more the better."

"There are still a few hundred kilograms of sulfur. There are preparations for crops in summer to prepare pesticides. As for the pharmacy, there are some in the pharmacy."

Lu Bu knocked on the table: "This is an important thing. Please buy two thousand kilograms first. I will check the quality. If it is suitable, at least 50,000 kilograms will be stocked."

Wang Heng was surprised: "So much money is spent."

Trade has been underdeveloped these days, and sulfur is only used as a small amount of pesticide for sterilization and insecticide. Nitrogen is used as a medicinal use and some charlatans who refine pills. Of course, as long as the money is in place, the goods are not a problem.

"You don't have to worry about money. Just purchase according to market price. The quality of the goods must be good. You must not buy bad goods for cheap. Recently, I will allocate more copper coins cast by the coin metering workshop and start purchasing immediately."

Wang Heng immediately recorded one by one: "Don't worry, lord, I'll make arrangements right away."

Lu Bu started to say the second thing again: "I ordered the Teng Guogongjiazhuang to hand over 200 double-bow crossbows before the tenth day of the second month. It was still based on the original design, and could be quickly installed on a wheelbarrow with a steering shaft."

"Okay, there are more than 10,000 big arrows used for crossbows in stock. If you speed up the production, you can make 20,000 pieces a month. It's just that you can catch up with the Chinese New Year, which will take a little time."

"You have to continue to be released during the New Year holiday, so you can keep fewer people on duty. After the seventh day of the New Year, you need to do ordinary arrows, crossbow arrows, and big arrows for car crossbows. The more you want, the better."

"Okay lord, I've made arrangements now."

If you want to put it in normal times, Wang Heng would make a few jokes. But today is different. Listening to Lu Bu's tone, it's going to fight. If you involve war, you can't joke. Go back and arrange it quickly.

The wooden craftsman, the craftsman who made arrow shafts, had his hands as fast as he could. The old craftsman who had been more than ten years old had almost become a afterimage, and the knife in his hand quickly cut the arrow shaft. On the contrary, those who were careful, wouldn't it be a big gap between novice and proficiency.

Wang Heng came over while walking, smiling and making the craftsmen feel furious.

This is their immediate boss and shopkeeper who are all the problems such as wages, benefits, promotions, etc.

Originally, there were supervisors with leather whips, and the craftsmen were not very motivated.

Later, Lu Bu asked for reform, and the supervisor of the whip was cancelled and the piece-based wages were implemented. Because he was responsible for food and clothes, he had basic tasks. After the basic tasks were completed, the piece-based money was calculated.

In this way, the old craftsmen are worth 600 yuan per month. Six or seven hundred yuan per month is absolutely high. After all, two kilograms of sorghum rice cost only one cent. Generally, craftsmen also have more than 200 yuan per month, and apprentices are the worst. They only eat and drink every month. Generally, they will only have wages after three or two months.

"From today, the work time will be extended by one hour every night. The general has given the task. Usually, it is delicious and delicious. No one is allowed to delay it at this time. Once it is investigated, no one can save you." Wang Heng issued an overtime task. The wooden instrument supervisor usually takes four hours a day, and now it is not too late to extend it by one hour.

The old craftsmen were very happy: "It should have been like this long ago. What can I do in four hours a day?"

The apprentices' faces are getting old and the work time has been extended.

"Everyone is cheered up, pay attention to safety and speed up, otherwise you won't have to think about having a holiday during the Chinese New Year."

When everyone heard this, it was not good. They only reunited with their families during the Chinese New Year.

"Don't worry, I will definitely work hard and will definitely not delay the construction period."

"Okay, I'll work hard. Before the holiday, I'll get some benefits for you to see if I can send you some seafood."
