After a math class, Zhou Qingfeng felt that he had a long way to go. The quality of the slaves is so poor, don't expect them to grow a smart brain if they don't have enough to eat. But although there are hundreds of slaves under his command, there are only a few dozen who know Chinese, and if you don't teach them, there will be no one to teach.

After class, those who should rest go to rest, and those who should go to work go to work. The three-shift work system will not change, and Zhou Qingfeng's fortress is still in the stage of excavating trenches and foundations, and the workload is very large.

Arrange for someone to cook fish soup for supper to replenish the strength of the slaves, and Zhou Qingfeng has to consume a bag of salt to go in as usual. He was either working as an overseer or acting as a human fish bomber during the day, and in just two days, the people of Kulen in the whole city knew that he relied on magic to bomb fish, and he gained a lot - just keep bombarding, keep practicing, Zhou Qingfeng felt that his 'lightning strike technique' was becoming more and more sharp.

After working all day and night, Chu Ying still had to run on time to train Zhou Qingfeng. The boring spear stabbing practice is two or three hours, and it will not stop until Zhou Qingfeng's physical strength is exhausted. At this time, Zhou Qingfeng would be distressed about why his body was so good, the strengthening of the 'blood marrow' made him recover his physical strength very quickly, but it also made him tired and scattered, extremely painful.

Abahai didn't come tonight, and neither did Darkhan. After Chu Ying left, there was only a small figure squatting with him beside Zhou Qingfeng. He was eating and drinking because of his physical exertion, and the little figure was drinking fish soup as if he had been hungry for days.

This little thing is the guy who suddenly shouted to ask questions when Zhou Qingfeng was in class, but it ...... and is not a human at all. It has shaggy hair, thin arms and legs, and two large eyes, but they are small.

It was a non-human creature roaming the mountains, and no one could name it. Its curiosity was so strong that it secretly ran to Zhou Qingfeng's fortress construction site, listened to half of the math class, and tried to ask questions. And when it appeared, the slaves who had been gathered were frightened and fled———— mountain spirits and wild monsters and other things have many abilities, and people have always feared them.

"What's your name?" Zhou Qingfeng was full, and then he had the spirit to ask what this monster he had encountered? He wanted to ask Chu Ying about this, but this little thing immediately fled when he saw Chu Ying, and in the blink of an eye, he ran into the woods near the construction site.

When Chu Ying left, the little guy ran out again, and by the way, he drank Zhou Qingfeng's fish soup and drank a round belly. Zhou Qingfeng asked it its name, but it didn't answer, dropped the soup bowl and swooped and disappeared. It wasn't until the next day that Old Man Sun listened to Zhou Qingfeng's description that he said uncertainly: "This may be a woodland servant." ”

"What woodland servant? Servant of the forest? Zhou Qingfeng was even more strange.

Old Man Sun scratched his head and said, "I've also heard about it, but I've never seen it." The Jurchens live in the depths of this mountain range and are familiar with all kinds of mountain spirits and wild monsters. There are many monsters in their rumors that we Han people have never heard of, and this woodland servant is one of them.

It is said that this thing is a servant of the mountain god, looks like a child of four or five years old, bold but alert, likes to steal things, is good at learning to speak, and likes to take care of trees and flowers, and its name comes from its habits. I haven't heard that this thing will harm people, but I haven't heard that this thing has any ability, so there is no need to care too much about it. ”

The monsters that Zhou Qingfeng encountered before were all kinds of ghosts, and he was very curious about this servant. Last night, the little guy suddenly came out to ask a question, and even asked Zhou Qingfeng to teach the math class again, which shows that his courage, curiosity and desire for knowledge are also very great. Zhou Qingfeng spoke again from the beginning in front of more than a hundred slaves, and seemed to gain the favor of this little guy.

But this servant came as he said he would, and he really didn't know how to communicate with him. In addition, it didn't seem harmful, so Zhou Qingfeng could only put it aside and deal with some other important matters on his construction site first. For example, he moved the bicycle in the space-time island to the end of the Ming Dynasty, and what he got after the space-time conversion was a ...... and a two-wheeled wheeled cart.

A large number of items need to be carried on the construction site, and it is too physically demanding to carry or lift it on the back of a human being, and it is extremely inefficient. Zhou Qingfeng felt a headache when he watched the slaves laboriously carrying dirt in wooden baskets, he needed a cultured, disciplined, and cohesive subordinate, and now most things were developing in a good direction, but the extremely heavy manual labor made them not strong.

This requires the improvement of labor tools.

Zhou Qingfeng tentatively got five trolleys first, and the shape of this thing is the plate cart used in modern rural areas. Don't look at it inconspicuous, the technology content is really not low, and it took a lot of spiritual power to transport it. The wheels are rubber, which is suitable for pushing on uneven ground and also greatly reduces drag. The bearings in the axles are even more high-tech, and they will never be able to do it by craftsmen in the late Ming Dynasty.

A trolley can easily carry more than 200 kilograms of items, it can greatly reduce physical exertion, and it can be pushed quickly. Dirt, wood, even tools, food, these can be used to carry it. With just five trolleys in use, the labor efficiency of the entire construction site can be increased by 30%.

For the laborers, this thing is simply an artifact. Heavy labor instantly becomes easy, pushing it can make people happy, and running can even make wind under your feet. The appearance of five trolleys once again triggered a novelty boom in construction site slaves, which was the same as Zhou Qingfeng's use of magic to fry fish, which brought them great blessings.

Who doesn't want to work a lot and be brisk?

The appearance of the board car made the nobles in the city very envious, they all thought that this was something made by Zhou Qingfeng, and they also expressed their desire to buy it. It's just that this time, Zhou Qingfeng refused to sell it on the grounds that the quantity was too small.

Inside the construction site, Zhou Qingfeng said that only people who study well and have a good brain can go to push the cart, work easily, and have more time to continue learning. In the same way, only those who obey orders can get more food and live better.

In order to organize his slaves, Uncle Zhou was really heartbroken. With his repeated propaganda and coercion and temptation, this small construction site finally set off a wave of study and work.

Hundreds of slaves were organized one by one, in groups of five, to help each other and supervise each other in life and work. Each group is a small group and is distinguished by color. The honor of the collective is greater than that of the individual, and all rewards and punishments are also carried out by the collective.

From small collectives to large collectives, there are also confrontational learning and labor competitions between different collectives. Zhou Qingfeng put more food, better tools, and more effective management into it, hoping to firmly control the minds of all slaves on the entire construction site.

Regardless of whether these slaves were exchanged by Zhou Qingfeng himself, or sent from Dashan Beizi, or borrowed from Chu Ying's subordinates, they were refined and forged again when they arrived at the construction site. When the time slowly entered the end of September 1615, Zhou Qingfeng finally obtained some slave troops that were slightly usable and could be easily commanded.

And most of the slaves were too muddy to hold up the wall.

The number of trolleys on the site has increased from five to twenty, and the increase in transportation efficiency has increased the progress of the fort construction several times. The wooden fence has been fully constructed, and even the trench outside the fence has been dug - in order to speed up the excavation of the trench, Zhou Qingfeng also invented the 'lightning blasting method'.

It is to dig a deep pit in the ground, fill it with water, and a 'lightning strike' blast into it. The electrolysis of water by electric current produces a large amount of hydrogen and oxygen gas, and then explodes again, and a very large crater appears. This trick also greatly accelerated the progress of the project, and also reduced the labor intensity, and the slaves now admired Zhou Qingfeng to the point of throwing themselves to the ground, and basically regarded him as a god.

The improvement of labor efficiency has greatly increased Zhou Qingfeng's flexibility in the use of labor. His small fortress was almost finished, and he no longer needed so many slaves. So he built a new fire kiln and an iron-making furnace on the vacant land of the lumberyard.

The early kilns built in the city were too small and were largely experimental in nature, used to train skills and train slaves. And now, about a month later, the scale of this second fire kiln is more than ten times larger than the first. Zhou Qingfeng trained more than 30 potters to produce pottery.

It was with the continuous production of pottery in this fire kiln that Zhou Qingfeng won the trust, support and help of the aristocratic class in Ekhkulun City. Although those Baylors and Bayers all seemed ignorant and arrogant, it would be a great blessing as long as they did not come to make trouble.

For the rapid changes on the construction site, Mao Adaa always has hatred and resistance. He received a set of pottery cups and pottery bowls from the construction site management office today, but muttered in disgust: "It's like the New Year to send such a broken thing, and the minions in this place are really ignorant." ”

Mao Ah was unhappy, but the slaves who were attached to Zhou Qingfeng were very happy. When there is a surplus of pottery fired, it is given to outstanding personnel as a reward. Although it is only a worthless thing, the constant rewards keep the motivated slaves quite enthusiastic about their work. They followed Zhou Qingfeng to work hard for a month, not only did they not become thinner, but gradually became stronger.

"It's just a bunch of minions who work as coolies, what's there to be happy about." Mao Ah Da returned to the carpenter's group with the pottery he had given him, and the group had set up a workshop where five slave apprentices were busy working. The tools they used were rudimentary, not even planers, saws, only an axe. A discerning person knows at a glance that this is a fire axe.

With such an axe, five slave apprentices took turns wielding it. Their job is to make all kinds of rulers, because all kinds of measurements need to be carried out on the construction site. Seeing his apprentices using heavy axes to cut and process wood, Mao Ada's heart kept sneering - what if he taught these apprentices? The lack of metal tools made it impossible for them to do anything at all.

"Hmph, Zhou Qingfeng's kid is also whimsical. He thought he could become a carpenter by throwing a few minions at me? Dream on. Look at the stupidity of these minions, they won't be able to do anything in 10,000 years. Mao Ada's heart kept slandering. He hid his own tools like treasures, and he just didn't take them out and use them anyway. If asked, he directly deduced that he didn't have the tools at hand.

In short, Mao Ah Da is a slack worker, a mixed life with enough food and drink every day.

But now after more than half a month, a burst of cheers suddenly sounded in the construction site to break Mao Ada's dream, and some people kept shouting: "Molten iron, molten iron, molten iron in the iron-making furnace!" ”
