Meng Tian has been very bored these days. His grandfather was sent by Lu Buwei to attack the State of Wei just after he came back, while his father was busy cleaning up his younger brother Meng Yi. Meng Wu's nose was crooked in anger, and now the father and son are still fighting wits, Meng Tian, ​​who was neglected, yawned while watching the play.

In fact, he really wanted to go to the battlefield with his grandfather, but he couldn't say it, because if he said it, he would be beaten...

Meng Tian yawned again, his mouth grew a little bit by accident, his father saw it, Meng Wu couldn't find Meng Yi and was annoyed, seeing Meng Tian's sloppy appearance, all the anger sprayed on Meng Tian.

"Stinky boy, what are you looking at?! Hurry up and go to Zamabu!"

Meng Tian quickly pointed to a place: "Father, Meng Yi is here."

Meng Wu followed the direction Meng Tian pointed, and sure enough, a child who was poking his head was hiding behind the door and observing his father secretly, and when he saw his elder brother bought him, he immediately disappeared behind the door.

Meng Wu was furious, picked up his whip and chased after him, Meng Tian took advantage of this opportunity to slip to the back door to escape from his father's claws, and took his horse away by the way.

36 meter No.15 meter, tune the tiger away from the mountain√

Meng Tian nodded in satisfaction, and after confirming that Meng Wu hadn't chased him, he swaggered towards Mo Dou's 'Baidu' workshop.

At this moment, Mo Dou has given up studying the bubbles in the glass, but Umbrella is still insisting on it. Seeing that Umbrella is so interested, Mo Dou will go with him. What if Umbrella is really developed?

With this kind of good wish in mind, Mo Dou let go completely, handed over all matters related to the glass to the umbrella, and then plunged into the work of making the overturned car.

Although he has seen the appearance of overturned cars on TV, and more or less seen them in various tourist attractions, and he even bought small toy overturned cars, Mo Dou still fell into difficulties.

The overturned car, also known as the keel waterwheel, is a keel waterwheel used by Chinese folks to irrigate farmland in the old days.It is the earliest and oldest agricultural water vehicle in the world.

The overturned car first appeared in the Han Dynasty and was built by an eunuch named Bi Lan.Keel waterwheels are still used in the villages of country Z until modern times, and the predecessor of the keel waterwheels is the rollover made by Bi Lan.

"Book of the Later Han" Volume 1 "Biography of the Eunuch Zhang Rang" records: "Yeting ordered Bi Lan to cast bronze figures in four rows in Canglong and Xuanwu Que. Four bells were cast, each receiving two thousand dendrobium , the county (hanging) in front of Yutang and Taidian. It also casts Tianlu shrimp scorpion, spits water in the east of the bridge outside Pingmen, and turns the water into the palace. It also makes overturned and thirsty birds, which are applied to the west of the bridge and sprinkled on the north and south suburban roads. , so as to save the common people the cost of spreading the road." Note [-]

In other words, the rollover at the beginning was not used for agricultural irrigation, but was used to sprinkle water on the side of the road, which is equivalent to a modern water sweeper.Mo Dou couldn't help but think of those big water trucks that wandered around the city every day in summer, and sprinkled water all over his body while singing happy birthday...

According to the above records, this guy Bi Lan not only made the overturned car, but also made a lot of messy things in the palace, including a "Tianlu" (the name of the beast in myths and legends) that can spit water, and These things still work on their own.

Mo Dou seriously doubts the authenticity of the Sunflower Canon, "If you want to practice magical skills, you must first go to the palace", maybe the magical skills are inventions, look at Cai Lun, then look at Bi Lan...

Of course, this is just Mo Dou's head, and the truth of history is that these eunuchs just tried their best to attract the emperor's attention, and obscene tricks are just a method.

Mo Dou looked at the things he made, and then looked at the overturned car in the Baidu pictures, and sighed sadly, he was a little bit shocked, why did he make a bucket in a long time?

That's right, the ink fountain did not make a rollover at all, but a bucket was barely made: a long rope with a water container (even if it is made of bamboo strips or rattan) was placed in the middle, and two people and one person used it Standing on one side of the bank, you can pull the rope to pour the water from the river into the fields. (Students who can’t imagine, please Baidu by yourself, the author really can’t describe it...)

The appearance of this thing is extremely crude, and the production principle is extremely simple, even with the most primitive manpower, even an ink fountain can't be used.

When Mo Dou was struggling, Uncle Niu knocked on the door very well and said, "Young master, Mr. Meng is here."

Mo Dou threw the bucket in his hand aside and stood up: "Understood, I'll go see him."

The fact that he only made a bucket has dealt a huge blow to Mo Dou, and he needs to slow down.

In front of the hall, Meng Tian had been waiting for Mo Dou for a long time, when he saw Mo Dou slowly coming out from the back room, he couldn't wait to stand up and say hello: "Ah Dou, long time no see."

……

Forget it, Ah Dou or something... Just get used to it, Mo Dou tried to smile: "Mr. Meng is good."

"Don't worry, I'm almost bored to death recently," Meng Tian waved his hands, and then looked at Mo Dou expectantly, "Did you create something new?"

...don't mention this to me, okay...

Mo Dou struggled to move his eyes away from Meng Tian's star eyes, and pretended to change the subject nonchalantly: "Mr. Meng, what's going on in the workshop?"

Seemingly seeing that Mo Dou didn't want to talk about this matter, Meng Tian very cooperatively took up the topic: "It's not a big deal, I just want to ask Ah Dou, what's the progress of the harness?"

Mo Dou raised his eyebrows, progress?You have to ask his apprentice about it, and he will produce something if his apprentice makes any progress.

In fact, this is not the first time that Mo Dou has been asked this question. Thanks to Meng Ao, Ying Zheng can see the anticipation of an old general for new military supplies from the battle reports from afar every day. Ying Zheng felt disgusted for a while, and it was really difficult to find a ghostwriter for Meng Ao...

But even though Ying Zheng was so numb that he was almost dead, Mo Dou didn't urge his lovely apprentice much, because he knew that every technological innovation was not made casually.

The saddle appeared in the Han Dynasty. In order to make it easier for the rider to get on the horse, a stirrup was installed on one side. It was not until the end of the Eastern Han Dynasty that there was a stirrup on each side for riding the horse. The only complete stirrup with an absolute date—the gilt wooden core stirrup was also in AD 415. It was found in the tombs of the 400s, and a rough calculation shows that there was an interval of [-] years!

But for Meng Tian's sake, you can also ask where the umbrella's progress is.

Uncle Niu received the instruction and quickly called the umbrella over, but the umbrella who was asked about the progress seemed to be in trouble.

Mo Dou consoled with concern: "If there is no progress, don't blame yourself, I'll just ask."

"It's not that there's no progress," Umbrella was a little embarrassed, "it's just a small discovery, but there are still problems to be solved."

"It's good to have progress, let's listen."

Mo Dou excitedly encouraged Umbrella to speak up if he found something, don't be afraid of embarrassment or anything!Completely ignoring myself who was still struggling with fighting just now...

"A few days ago, I found that if the horse ran too much, the horse's hoof would fall off easily. I wondered if I could make a shoe to protect the horse's hoof."

Meng Tian became excited, Mo Dou's eyes lit up, and he continued to ask: "Have you thought about how to make shoes?"

"No, if you are a person with shoes, they will wear out soon." Shan lowered his head in frustration, paused, and said cautiously, "I wondered if I could make iron shoes..."

Meng Tian interjected: "Impossible, the bottom of the horse's hoof is wide and the top is narrow, how do you put the iron shoes in?"

Shan faltered and said: "I just thought...whether I should just...nail...on it..."

"Nail it?!" Meng Tian repeated in shock, "How did this horse suffer?"

Mo Dou stood up excitedly and retorted to Meng Tian: "Of course I can bear it! The horse's hoof is not all meat, but part of it is something like human nails. Of course the nails won't hurt."

Meng Tian remembered staring: "Just kidding! Let me tell you, A Dou, even if I, Meng Tian, ​​died in battle, on the battlefield, or fell off my horse, I wouldn't let my horse have such things nailed to its feet!"

Mo Dou ignored the still swearing Meng Tian, ​​stood in front of the umbrella and asked, "Have you tried it?"

Shan shook his head: "I made iron shoes, but I didn't dare to try..."

In order for him to study harnesses, Mo Dou specially raised a horse in the workshop for him to experiment with. The horse is precious, so how dare you put horseshoes on the horse's hooves casually?Although the horse has nothing to do every day, it only wastes food and spits on the umbrella...

"Then try it now!"

Mo Dou immediately took the umbrella and walked to the stable. He was now immersed in the joy of his apprentice being a genius, and even had the urge to simply hand over the overturned car to the umbrella...

Meng Tian hurriedly followed behind Mo Dou, his Ma Ke was also in the stable, so Mo Dou couldn't admit his mistake and drag him to experiment!

However, the bloody scene Meng Tian imagined did not happen. When the horseshoes were nailed, all the onlookers could not help closing their eyes except for the two masters and apprentices, as if nails were nailed to their feet. The fat and strong horse involved didn't react much at all, and even spit on the face of the umbrella in a leisurely manner, and seemed to like the umbrella very much...

Meng Tian looked at the well-responsive horse in disbelief, and said in a daze, "Adou, you can also put iron shoes on my horse..."

……

Meng Tian looked at his horse's shoe with satisfaction: "In this way, I can go to my grandfather."

Mo Dou was stunned when he heard the words: "Shouldn't this thing be reported to the king, and the king will send someone to mass-produce it and then send it to the battlefield? Even if you find General Meng, it will be useless."

Isn't Meng Ao attacking Wei, and you can't be a horseshoe, what are you going to do?

Meng Tian raised his eyebrows and smiled, feeling quite strategic: "When Meng Tian saw this thing, he couldn't help being overjoyed, so he impulsively went to the battlefield to tell his grandfather about it, and please tell the king about it."

Mo Dou is silent, so you just want to go to the battlefield, right?

Meng Tian patted the horse proudly, feeling that he was smarter than his younger brother by more than one grade.
