Holding Cui Yingying in his arms, Li Yin smiled triumphantly: "Then how are you going to thank me!", the strange hand started to move.

  Cui Yingying's cheeks were red, and she broke away from Li Yin like a deer, and said angrily: "Your Highness is really bad, thinking about that in broad daylight!"

  Li Yin said righteously: "I just want my lady to pat me on the shoulders. Where is my lady thinking!"

  Cui Yingying ignored him, and pushed Li Yin away, "His Royal Highness should go to work, Yingying wants to change clothes, the young lady of Dou's family will come here later, and I plan to go to Beishi with her!"

   "I also want to change clothes, why don't we change together!" Li Yin stretched his head and squeezed into the room, but he was still locked outside, "This girl is getting more and more unruly!"

  Nothing happened, Li Yin thought of the walking tractor in the Nanhe Warehouse. The winter wheat would be out of season if he didn't plant it, so he simply asked some slaves to teach them how to use it.

   Just do what you say, Li Yin took Jin Daqian to Nanhe, and now Cui Yingying is in charge of the affairs in the mansion, he has to let Jin Daqian take care of the outside affairs, and follow him, how can he do without a few brushes.

   Arriving at the warehouse, Li Yin asked Jin Daqian to find a smarter servant. This person will be the first batch of people in Datang to use walking tractors, and will surely be recorded in history.

  The workshop under construction was right next to it, and Jin Daqian took the order and ran over.

Li Yin walked around the walking tractor. This kind of walking tractor is light in weight, compact in size, flexible in operation and strong in adaptability. Equipped with different agricultural machinery, it can be used for plowing, rotary tilling, leveling, crushing soil, etc. A variety of field operations, coupled with a trailer, can also be used for short-distance transportation. It is a versatile agricultural machinery. Li Yin also considered for a long time before deciding to buy this old-fashioned machine. This kind of machine, which Li Yin played with when he was a child, basically has the same technical content as riding an electric car.

   After a while, Jin Daqian brought a man over. This man was of medium height and had a full mouth full of stubble. When he saw Li Yin, he bowed and saluted, and stood awkwardly in front of Li Yin.

   "What's your name?" Li Yin asked.

   "The cheap slave Guo Mingda!"

  Jin Daqian interjected at this time: "Yang Li said that among these slaves, he is the smartest and can learn everything quickly, so I recommend him!"

  Li Yan looked at him again, pointed to the walking tractor on one side and said: "This kind of thing is called a walking tractor, and it is a kind of farming tool. I will teach you how to use it later. Do you know it by heart?"

   "Yes, Your Highness!" Guo Mingda peeked at the walking tractor that Li Yin was talking about. He had never seen such a strange thing before.

Walking tractors do not have steering wheels, but have handles similar to those of bicycles, except that the handles extend in the opposite direction to the nose, and each handle has a hand brake similar to that of a bicycle brake, called a clutch. Turning the handle can control the direction , There are two covers on the top, one is opened to drain oil, and the other is used to pour cooling water to cool down.

  Li Yan personally oiled it and took the crank handle. This kind of machine does not start automatically, so he can only use the crank handle to enter the shake port on the machine head and turn it hard. When the belt starts to rotate, pull out the crank handle.

  Guo Mingda faithfully carried out Li Yin's order, and followed Li Yin step by step to watch his every operation. Jin Daqian was also very curious and followed along to join in the fun.

Speaking of it, it has been two or three years since Li Yin was tinkering with this thing last time, and he didn't have any ideas in his mind, and he was a little nervous when he started the machine with the crank. Serious, but the ability to swell a certain part is still there.

   "Get out of the way!" Li Yin ordered the two of them, gritted his teeth and shook it vigorously. The initial speed of this thing must be fast enough, otherwise it would not start at all.

   Jin Daqian and Guo Mingda didn't know why, they looked at Li Yin's movements strangely, only to see Li Yin shook a few times and then stopped.

"Failed!" The nose of the plane made two soft "chugs" and then fell silent. Li Yin was not discouraged. This is normal. He held his breath and concentrated on it. At the beginning, he called out "rumble", and the crank also turned, and Li Yin quickly pulled out the crank.

   Then, he got on the tractor, controlled the speed to the lowest gear, and drove the tractor out of the warehouse.

  Jin Daqian and Guo Mingda are completely stupid, this thing can move by itself? Thinking about it, the two rushed out of the warehouse, and the King of Shu was still there!

   After driving for a short distance, Li Yin stopped and looked at the pale-faced two people. Li Yin smiled and said, "Don't be nervous, this is not a monster, it's just a tool like a cow or a horse."

  Jin Daqian glanced at the tractor, and said cautiously: "Your Highness, he won't hurt anyone!"

   "No, if you don't believe me, touch it, it's more obedient than a horse!" He said and dragged Jin Daqian onto the tractor.

  Jin Daqian's face turned green instantly, but he didn't dare not listen to Li Yin's words, so he bit the bullet and got on the tractor, only trembling with fright.

  Li Yan looked funny, and said: "Open your eyes, he won't eat you again!"

  Jin Daqian opened his eyes when he heard the words, waited for a while and saw that there was no movement from this thing, he boldly touched the machine, and seeing that there was still no movement, he became more courageous and touched it curiously.

   Li Yin saw that it was almost done, let him come down, Guo Mingda is the one to teach this time, Jin Daqian is purely watching the fun.

  With Jin Daqian’s precedent, Guo Mingda didn’t seem very nervous. He started messing around with the tractor, while Li Yin explained the function of each component to him. Guo Mingda listened carefully and was very attentive.

  After explaining all the functions, Li Yin asked Guo Mingda to operate it himself, while he stood aside and watched. You have to practice everything yourself, otherwise you will never learn it.

Recalling Li Yin's movements, Guo Mingda learned how to operate. When he started the machine, Li Yin's heart began to lift, and he began to command from the side: "Strength, you must use force, you know?", "Shake Pull out the crank when you start your own spin!"

After failing seven or eight times, Guo Mingda was sweating anxiously. His Highness gave him a chance because he took a fancy to him. He couldn't be so ashamed. His mouth and teeth had to be mobilized, thinking, he roared and shook his hands desperately.

   "Rumble..." Under Guo Mingda's rapid shaking, the machine finally rang. Guo Mingda was overjoyed and turned his head to Li Yin and shouted, "Your Highness, I succeeded!"

Li Yin was overjoyed at first, but Guo Mingda's was still on the handle. Obviously he was too excited and forgot the next step. He shouted: "Quickly pull out the handle!", but it was too late, and then he saw It was thrown out by the huge force of the engine and hit Guo Mingda in the stomach.

   "Ouch!" Guo Mingda screamed.

  Jin Daqian and Li Yin immediately ran over, helped Guo Mingda up and said, "How is it?"

  Just **** for a while, Guo Mingda rubbed his stomach and stood up, saying: "It's okay, it really hurts when this thing hits someone!"

  Li Yan just kicked his ass, "I told you to pull it out, this is hitting you on the stomach, if you hit your head, you will be bleeding!"

   "Your Highness, the lowly slave is wrong!" Guo Mingda said with his head down.

  Although there was an accident, Guo Mingda finally learned how to start the machine, and Li Yin said in a good mood: "Now try to drive it!"
