Lord of all the people: Only I can summon the immortal troops

"I come from a small place in the Elf Empire close to the human country. My mother is the leader of the tribe, but a week ago" she glanced at Zhang Lu timidly as she said this, "a group of human slave hunters broke in. In our tribe, they massacred the guards and captured the children. My mother asked a team of guards to protect me and escaped, and then went back to fight those people."

She was a little sad when she said this. Her mother was probably in danger. "We originally wanted to escape to the Elf Empire, but that group of people blocked our way and kept driving us towards the human country. They were protecting me. And in the process of crossing the mountains, all my guards were killed."

"I can't go back through time alone. Even if I go back, my tribe has disappeared, so I beg the Lord to take me in."

Zhang Lu looked at the weeds outside the door and was a little moved. Like Kong Xin's elves, she was a natural elf, and there were many branches among the natural elf. He was very optimistic about her ability to produce plants and identify medicinal materials.

Zhang Lu looked at the snow-white skin of this elf, especially the scars on her skin that were in sharp contrast to the white and tender skin. It didn't seem like she was lying. Although his territory was not short of food, it was impossible for the members of his territory to Only fairy boys and yellow scarf warriors must reach level three to be able to live without grain. Naturally, the more food, the better.

What's more, there is a forest farm, and those small trees also need to be stimulated, as well as fodder for the future horse farm, all of which require Nina's ability.

"Follow me." Zhang Lu led Nina to the fields in the territory. The scenery in the fields was beautiful. Many yellow scarf warriors were doing farm work. When they saw Zhang Lu coming, they all stopped and saluted.

A small canal is introduced from the upper reaches of the west of the territory to irrigate the fields. However, it has been the dry season recently, and some fields further away do not have enough water sources at all, and their growth is somewhat slow.

"Can you stimulate the growth of these crops?" Zhang Lu pointed at the rice in the field and looked at Nina. If you can, it will be a good thing for their territory.

"Of course!" Nina found something to do, and she felt better. Green light emitted from her hands. Under the light, the rice seedlings in the farmland suddenly grew. They were just small seedlings. When it reaches the size of the finished product, it’s just about ready to produce rice!

"Not bad." Zhang Lu nodded. It's spring now. These rice should have matured in summer, but now it seems that we can harvest a wave before summer. This is the magic of natural elves!

"These children can only be born to this point. Next, they need to grow naturally, otherwise their output will be greatly affected." Nina turned around and looked at Zhang Lu with her own eyes, as if she wanted to see Zhang Lu surprised. expression.

It's a pity that Zhang Lu only had some approval. Although the magic was miraculous, he was already accustomed to seeing magic.

"Okay, from now on you will be a member of our territory and will be responsible for taking care of the crops." The moment Zhang Lu finished speaking, one more elf appeared on the list of members of his territory.

"However, there are indeed some unreasonable aspects of this farmland." He looked back at the large farmland.

"Bring a pen and leather, Ye Qi, go get Ye Kui." Zhang Lu said to Ju Ming who was following him. He knew that Ju Ming would have a lot of dry animal skins on him for recording.

After receiving the two things, Zhang Lu began to wave on the animal skin one stroke at a time. This was a rough sketch, not very accurate. Soon, a round thing appeared on the animal skin. Come out, there is something like a fixed wooden board on top of this round thing.

Then he picked up the second animal skin and drew some axis-like things on it, drawing the front, side and cross sections of the entire thing. This almost used up the animal skins prepared by Ju Ming. .

Zhu Ming and Nina were all surrounding Zhang Lu. They didn't understand what Zhang Lu was drawing or what he wanted to do.

"It's done, and then..." After Zhang Lu finished drawing the first thing, he started to draw the next one, but this one was not an object, but a method of building a wall.

The brick kiln that Ju Ming mentioned before has begun to produce bluestone bricks, but he found that their method of building walls is to simply stagger each layer of bricks, and then build two rows and glue them with a kind of plant mucus from this world. The two rows in the wall Just like they are separated, they are not a whole. Even the buildings in New Blue City use this method.

What he is painting now is a wall-building method called Yiding Yishun, which will make the walls tighter and stronger.

After he finished drawing, Ye Kui was already standing behind him, but did not disturb him.

"You're here just in time, take a look at this." Zhang Lu held the first thing to draw.

"You see, this thing is called a waterwheel. The water flows under the waterwheel and passes through the wooden board on the big wheel. There is a concave space inside the wooden board. The water flow pushes the wheel to rotate, and then the groove carries the water. At the highest point, the diagonal design will allow water to flow here." Zhang Lu took out another drawing.

"After the water flows into this aqueduct, it flows all the way to different fields through bamboo pipes. In this way, we only need to build a waterwheel at the mouth of the river, and we don't have to worry about the water not being able to irrigate the farmland close to the territory."

"Although you are a swordsmith, I believe it should not be difficult to make this with your hands-on skills." Zhang Lu handed all the drawings to Ye Kui. Although he is a blacksmith and not a carpenter, he is a man with strong hands-on skills. , it shouldn’t be too difficult to make a waterwheel by analogy.

"Of course, I promise to complete the mission of the lord!" Ye Kui cupped his fists. Zhang Lu had already said it in such detail. If he still couldn't make such a thing, he would be really embarrassed.

Nina's eyes lit up as she watched the waterwheel explained by Zhang Lu. In the past, the water sources in her tribe were all gifted by God. If it was in the dry season, people in areas farther away from the water sources would have to send people to use the water system once a day. Magic creates artificial rainfall, and there are not many natural elves who are good at water magic, so those few elves in the dry season are exhausted every day until their magic power is exhausted.

And this little thing solves the problem of water supply from water sources to distant places?

All you need is a water truck to carry the water to the highest point and pour it into the aqueduct, and then use the height of the aqueduct to connect a bamboo pipe diagonally downward to send the water to a distant place!

Elves have always been famous for their exquisiteness, and many elves think that humans are savages, who are only a little better than those rude orcs. But at this moment, she suddenly felt that humans who can create such things, Seems smarter than the elves!

"If you have time, make a few more waterwheels, then replace the aqueduct with a sealed water tank, and install this one at the end of the bamboo pipe." Zhang Lu took out another drawing.
