After settling down, and finding that the person in front of him had clear eyes and spoke clearly and loudly, Ma Chao had already concluded that he was just too emotional, and he was not mentally ill because he was crazy because of scientific research. Even so, Ma Chao still felt a little awkward when he grabbed the cuffs with his big rough hands, and ripped off his hand and said, "Zhou Maitian....... By the way, your junior brother Zheng Hun, right? ”

After taking a closer look at the face covered by the messy hair, Ma Chaocai struggled to see the previous vague outline from under his full beard: this person is indeed Zhou Maitian, and he is also a descendant of Lu Ban's high disciples, in addition to being good at carpentry, he is also good at water conservancy. Ma Chao has inspected the arsenal several times, and he still has a trace of impression of this week's wheat field.

However, what he had a headache was, why did Zhou Maitian, who used to be behind Zheng and have a red wooden vertebral logo pinned to his chest, become like this now?

What's even more troublesome is that under the tugging of the cuffs, Ma Chao suddenly found that this product actually turned over and grabbed his other cuff.

Ma Chao couldn't help but feel a little strange, and thought it was his mistake. After pulling again, the wheat field was wrapped around again that week, and Ma Chao's cuffs were not let go at all. This surprised Ma Chao, and asked, "You can still grab hands?" ”

"What grappler?" After Zhou Maitian saw his lord, he had already regained his senses, but in a state of ecstasy, he didn't think of kneeling down and saluting at all, but suddenly smiled: "The lord is talking about this kung fu of taking people?" This is also my own creation, and after I took those tools easily, I practiced skill......."

'The grabber comes from the craftsman who plays tricks with tools? Ma Chao was a little dumbfounded, but if he said that the grappler had nothing to do with Zhou Maitian, how could he explain the matter of his cuffs?

Saying that, Ma Chao was interested, pulled out Zhou Maitian to the outside of the arsenal, and said after standing up: "You come to capture me." ”

"Lord, you are ......."

"If you want to catch you, you will catch it, what so much nonsense!" Ma Chao opened his mouth, but saw a wicked smile in Zhou Maitian's eyes: "Lord, I have already caught you........"

'I'll it! This thing also knows the art of war, and he knows how to hide from the world! Ma Chao looked back, and sure enough, he found that Zhou Maitian had rushed behind him and hugged his waist tightly. After that, Ma Chao didn't talk nonsense, and he rushed forward, wanting to throw Zhou Maitian away. But in fact, as Ma Chao expected, this week's wheat field was like sticking to Ma Chao's body, let Ma Chao struggle like a wild donkey, he could always grasp the best sense of balance when he landed, and then instantly wrapped around the opponent like a dog skin plaster.

After sweating, Ma Chao found that he had eight hundred and ten ways to kill Zhou Maitian, but he really couldn't throw him off. In the end, Zhou Maitian was entangled in anger, and one threw himself backwards and pressed Zhou Maitian under him: "What the hell do you say you can't grab hands?!" Master crosses ....... I can't get rid of you in clothes! ”

"My lord....... Crush me! After Zhou Maitian was stunned by Ma Chao's big move, he only felt that his bones were falling apart, and he forgot what he wanted to say when he grabbed Ma Chao's cuffs........

At this time, after Zheng Hun heard the news, he also rushed out of the arsenal. Seeing the scene of Ma Chao and Zhou Maitian being entangled, he was stunned, his eyes were demented, and he didn't know whether to step forward and salute or retreat silently.......

At this time, Ma Chao suddenly found that his posture with Zhou Maitian was very ambiguous: Zhou Maitian didn't forget to grab Ma Chao before he fell to the ground, so his feet were tightly entangled with Ma Chao's feet. And the hands of the two, you are also holding me, and I am holding you. What's more serious is that at this time, Ma Chao and Zhou Maitian's faces were only a few centimeters away, and the face-to-face and body-to-body scene was enough to make Zheng Hun, a silver master, stunned.......

"Let go! Let me go! After Ma Chao was stupid for a while, he immediately reacted and said with a red face.

"I won't let go, my lord, you are using fraud!" Sure enough, the mind of a scientific researcher is not something that ordinary people can understand. And Ma Chao saw that Zheng Hun's face was becoming more and more suspicious at this time, and he couldn't help but be annoyed and angry, and yelled: "Then, don't blame me!" ”

After finishing speaking, Ma Chao took out the momentum in his body, locked with a murderous aura, and after breaking free from Zhou Maitian's shackles, he directly cut his hand and hit Zhou Maitian's neck, immediately making the thing fall asleep.

After clapping his hands, Ma Chao didn't wait for Zheng Hun to salute, and said directly: "I want this Zhou Maitian, take it to the military training hall, and teach the shadow with Wang Yue!" ”

"Huh?" Zheng Hun couldn't react for a while, and forgot to salute, so he said directly: "Lord, are you going to teach martial arts?" ”

"Yes, this guy actually created his own grappler, which is most suitable for Shadow Life to capture scouts or kidnap others......." Ma Chao couldn't think of anything to do with the carpenter, and after shaking his head, it could only be attributed to Zhou Maitian's talent.

"However, the junior brother has just invented the keel waterwheel, and his subordinates are about to report this to you......."

"The great water of the entire arsenal is his masterpiece?" Ma Chao's face darkened a little, and he suddenly felt that this Zhou Maitian was really an all-round compound talent.

"The stagnant water in the courtyard has been cleaned up, and the lord is invited to come in and watch." Zheng Hun also shook his head, and he also had a little headache for him, a junior brother who had entered the demon in scientific research.

"Isn't this just a rollover....... Seeing the wooden machinery made of wooden planks and grooves of different sizes cut like a keel, Ma Chao suddenly said the modern name of this keel waterwheel.

Ma Chao, who is a technician of the agricultural base station, knows that the overturning car is one of the most famous agricultural irrigation machinery in ancient China, which is driven by hand, foot, ox, water or wind. The keel blades are used as chains, lying in rectangular long grooves, and the body is inclined to the river or pond. The lower sprocket and part of the body are submerged in the water, and the sprocket is driven, and the blade is scraped along the groove to lift the water and send the water out to the upper end of the long groove.

In this way, the water can be transported to the place where it is needed, and the water can be continuously drawn, and the efficiency is greatly improved. In addition, it also has the advantages of easy operation and handling, and can transfer the water intake point in time. It can be used for irrigation and drainage.

The earliest application of chain drive in ancient China is in the overturn, which is a major improvement of agricultural irrigation machinery.

"Overturned?" Zheng Hun was stunned for a moment, but then explained: "Lord, this thing is not a rollover, but a keel rollover made by the eunuch Bi Lan." After the Yellow Turban Rebellion, the object gradually disappeared. It took half a year for Senior Brother Zhou to make this thing and improve it. ”

"Bi Lan? Improve? Although Ma Chao does not have a deep memory of the history of the overturn, he knows that the overturned car was indeed made by a eunuch among the ten permanent servants in the Eastern Han Dynasty. Later, it was improved by Ma Jun, a famous inventor of the Three Kingdoms, before it was applied to agricultural production, which greatly improved the water intake and irrigation efficiency of agriculture.

"I never thought that there were such characters among the eunuchs......." Ma Chao looked at the overturned car, shook his head and smiled bitterly. Then he looked at Zhou Maitian, who had not yet woken up behind him, and his eyes were a little hesitant: This product is really a treasure!

"Yes, although Bi Lan is greedy and cunning, he does have some experience in woodworking inventions. It's a pity that after being brutally killed by the scholars, there is no keel waterwheel and thirsty black ...... in the world."

Thirsty Wu is a kind of water lifting tool that uses the principle of siphoning, and it is also an extremely useful tool for the agricultural production of the Ma family in Yongzhou. However, when Zheng Hun continued to talk about overturning and thirsty Wu, Ma Chao immediately remembered a water tool in the Sui and Tang dynasties: a water drum car.

As a result, he walked to Zhou Maitian's side with one step, shook it all the way, and after Zhou Maitian woke up, he asked loudly: "Can you get out of the water drum car?!" ”
