When the thief talked about playing yin, Usma fought a solid cold war.

The thief summoned everyone in front of him and said: "The plan is like this..."

After recounting the original plan, Li Ya yelled and said to the thief: "A thief, is it too wasteful for you to do this? In order to catch such a guy, you made 20 cars?"

Ji Zei pursed his lips: "What do you know, who told you that this car can only be used to seduce him? Can't I use these cars to loosen goods? For example, this time the fertilizer delivered to the White Bone Wasteland."

Ah Wei raised his hand and said, "My patriarch, I can transport it with the clansman."

"How much can you transport alone? One altar or two altars? If you use a car, you can loosen at least 20 altars each time. And a car only needs to be equipped with two to four people, which greatly saves manpower. Besides, there is a carriage for transportation, which saves much time than your long-distance transportation to two places." Ji Thief said.

Awei blinked.

The thief said: "For example, it takes four days for you to return to the Eastern Plains from the Bone Wasteland, plus two days for carrying and loading goods, and then four days from the Eastern Plains to the Bone Wasteland. This time, ten days. Ten. How much fertilizer can be transported in one day? If it is a carriage, 20 carriages can be worth 200 people. If it is transported back and forth, it can be achieved in six days at most. This saves manpower and time. It must be done. Come out."

Awei scratched his head: "The patriarch, why didn't you remember when you were in the Bone Wasteland?"

In a word, the Ji thief who asked was speechless.

After half a day, the Ji thief screamed: "Okay, that's it, Usma, don't go back to rest later. Let's get the design drawing of the carriage overnight."

Usma nodded, squeezing her chin and said: "Master Patriarch, I am also curious why you didn't want to make a carriage before."

Ji thief: "···"

"I can't forget it. Didn't I remember when I came back with my son this time?"

Seeing the thief was really angry, Usma and Awei both curled their necks: "Yes, you can."

The thief waved his hand: "Okay, Usma, let's go to the engineering department. Awei, you have installed the fertilizer within ten days. Oga, you think about the way to deal with the beast controller, and wait for Tushan to take it. When the person comes back, you hand over your opinions with him. This time, try to get the **** kid down in one breath. Damn, let the snake bite this bite. I can't spare him lightly!"

Seeing Ji thief's vengeful expression, Usma shook her heart, saying that if the patriarch behind her was stingy and stingy, she absolutely couldn't let it know, otherwise, she wouldn't even want to get a salary in her life.

Usma thought to himself, but the thief turned his eyes to fall on him: "Usma, why are your eyes so weird? Is there something hidden from me?"

Usma waved her hand quickly and smiled, with a mean look on her face: "No no, patriarch, you have thought about it, how could I hide anything from you, really!"

Ji thief: "···"

"Okay, I can barely believe you, let's go, don't sleep tonight." Ji Thief said.

Hearing that Usma slumped her shoulders, she said in her heart that the good days are over, but I still want to go back early tonight to get together with Ayin.

"Sister, can you stay and take care of me for a while?" Ji Thief asked.

Xue nodded: "Don't worry, Warrior, leave it to me."

With a hum, Ji Zee grabbed Usma by the collar and walked out.

The two came to the engineering department, opened the door, walked in, lit the fire, and Usma brought a few wooden boards and some charcoal.

Currently in the Lihuo tribe, this plank is used as a drawing, a drawing tool for snow, and a project plan for Usma.

Holding a piece of charcoal in his hand, Usma asked the thief: "Master Patriarch, what is the carriage like?"

At this time, Ji Thief also squeezed a piece of charcoal in his hand, and he groaned: "If it is a carriage, I will think about it."

When he said this, the first impression Ji Thief had in his mind was a tall and even luxurious carriage, but this idea was pushed down by him just as he first started.

That kind of large and luxurious horse-drawn carriage is just looking good at its prestige, and its practical value is not high.

The most important thing is that within ten days, Usma can't build those twenty luxurious carriages.

Therefore, Ji thief can only lower the requirements.

Anyway, the carriage was originally made for the purpose of transporting fertilizers, and was not used for imposing pretensions. It only needed to be beautiful and practical.

Ever since, Ji Thief thought about it seriously, and drew the shape of the cart on the board.

This thing is simple and durable, and the most difficult technique is just the problem of wheels and load-bearing drive shafts.

But for a while, Ji Thief drew a simple figure of the cart on the board.

Usma yelled, and asked the thief: "Is that this?"

The thief nodded: "That's it."

Usma took it over and looked at it: "This is simple, don't say 20 drives in ten days, even forty, I can make it."

Ji Zei pursed his lips: "Don't rush to make a military order. This carriage must be able to pull. If you can't, just make a model and put it here, you know?

Seeing a look of doubt in Usma's eyes, the thief pointed to the wheel and said: "Let these circles turn, so that it can play a role in pulling and sending goods."

Usma snorted, "Master Patriarch, is this a bit difficult?"

Ji Thief patted his chest: "Why, I'm afraid? With the two of us here, I can't overcome it overnight? Are you not confident in yourself or me?"

Usma waved his hand hurriedly: "No, it's not the patriarch. Yes, there are, and all have confidence."

Ji Zei nodded: "That's right, show the confidence of the person in charge of your engineering department. You can even drive a trebuchet, not to mention a small carriage."

With this remark, Usma said with great enthusiasm, clenching his fist and said: "Master Patriarch, don't worry, I will make it for you!"

Ji Thief smiled happily: "Don't worry, after making this carriage, I will give you two days off from the Engineering Department."

Usma's eyes lit up: "Really?"

The thief nodded: "Of course."

As soon as this guarantee came out, Usma was immediately energetic, letting go of her thoughts, and overcame all the design difficulties of the cart overnight with the thief.

At dawn the next day, when Zhen came to the Engineering Department with breakfast, Ji Zei and Usma were yawning, each of them with red eyes but still very energetic.

Hearing a voice, Ji Zei turned his head and smiled when he saw Zhen Zhen: "Sister Zhen, you are here."

Zhen hummed, put down the breakfast in her hand, squatted next to the Ji thief sitting on the ground and asked, "Is this a carriage?"

Ji Zei gave a hum, picked up the bowl with goat's milk, licked his lips and said, "It's not a waste of work this evening."

Usma straightened her waist and made a chuckle, babbling and laughing: "Hey, vacation."

Zhen reached out and took a wooden board and carefully observed it in her hand. She looked at the pattern on it, looked at it, and suddenly wondered.

"Warrior, what is this round one?"

Ji thief put down the bowl: "Which one?"

Hazel pointed at the tire position on the board.

The thief said, "This, this is called a wheel, which can travel on the ground."

Zhen Yi said, "Can this thing be made? Wouldn't it be troublesome?"

The thief glanced at Usma, and Usma laughed: "Master Zhen, you don't know about that. Last night, the patriarch and I have already figured out a way to make this wheel. I promise that there is no problem. ."

Looking at the two people full of confidence, Zhen didn't know why, but she always felt something was wrong.

But the two were happy, and Zhen was too embarrassed to pour cold water.

After staying there for a while, when the two had eaten breakfast, Zhen cleared up the dishes and turned around.

After another half an hour, the engineering tribesmen came one after another. When they saw Ji Thief, they were slightly surprised, because everyone knows that Ji Thief went to the Bone Wasteland not long ago. When did he come back?

Surprised to surprise, but everyone should be courteous.

Regarding this, the thief waved his hand without being polite, and then called Usman's right-hand man, and handed over the wooden board with the figure drawn last night.

These deputies looked at the carriage graphics on the wooden boards, one by one, all puzzled: "Master Patriarch, Master Usma, what is this?"
