After a few months, Zhou Shaobin saw something similar to a psionic locomotive again, and he was very excited to go up and try it, but Ling Yu stopped him and joked, although he didn't think there would be any problems, but after all, he hadn't tested it, he didn't dare to let Zhou Shaobin go for a test drive, not to mention that he was the prince, as Ling Yu's friend and brother-in-law, he didn't want Zhou Shaobin to have a chance.

"Brother Ling, what are you stopping me for, I haven't driven your locomotive before, and now you don't let me drive a harvester, so you said that you would teach me to drive." Zhou Shaobin complained with a bitter face, he also knew that Ling Yu stopped him for his safety, but he just wanted to try.

"Baked cakes, first of all, let's go to the palace to report the situation to His Majesty, and then, let's go to Huangzhuang to test the performance, and then I will teach you how to use it, so how about you try it in Huangzhuang?" Ling Yu smiled, this is the right way to open it.

"Okay, let's go." Zhou Shaobin immediately went over and received the harvester into the storage ring, pulled Ling Yu and left.

Seeing this, Ling Yu didn't say anything, and followed Zhou Shaobin.

Because Zhou Shaobin was anxious to drive the harvester, he kept urging the horseman to speed up along the way, Ling Yu was helpless, fortunately, no matter how fast the carriage was, it couldn't go anywhere, if Zhou Shaobin was asked to drive the psionic locomotive, according to the current speed after Ling Yu's upgrade, I am afraid that it would be able to drive to 100 kilometers per hour.

"Father, father, happy event." Zhou Shaobin didn't wait for the report, and hurriedly pulled Ling Yu into the imperial study.

"What's so much about it?" When Zhou Zhengxiong saw the two coming in, he said with a smile, and he didn't blame the two for being rude.

"Father, you see this is the spiritual energy harvester that Brother Ling just made." As he spoke, Zhou Shaobin took out the psionic harvester from the storage ring.

Looking at the psionic harvester lying quietly on the ground, Zhou Zhengxiong was also very surprised, approached and looked at it carefully, and asked, "Virtuous son-in-law, is this what you call a harvester?" How do I use it? Show me how. ”

"Father-in-law, this machine can't see its role here, and the son-in-law suggests that it is better to go directly to Huangzhuang to demonstrate." Ling Yu said respectfully, there are no outsiders now, and when Zhou Zhengxiong calls him so, he doesn't care too much about the etiquette of the monarch and the minister.

"In this case, I will go to the Imperial Village with you." After speaking, he called Yucheng and told him to prepare to go out of the palace to Huangzhuang, which is the royal field manor, and it is also the cheapest land rent, usually employing landless people nearby to farm, and the people are also happy to farm for the emperor, and the land rent is low and does not need to be exploited by the landlord.

Dozens of minutes later, Yucheng was ready to travel, the time was not long, but Zhou Shaobin felt like a year, and finally had the opportunity to drive something similar to a psionic locomotive, but he didn't know that this thing was very different from a locomotive, just talking about speed, this thing was very slow, at most a little faster than a human walking.

Along the way, Zhou Zhengxiong authorized Ling Yu and Zhou Shaobin to share a car with him, which made Yucheng on the side sigh, except for Ling Yuefeng, Ling Yu was the second courtier he had seen who was so favored by the emperor.

"Son-in-law, how efficient is this harvester?" In the luxury carriage, Zhou Zhengxiong asked.

"Father-in-law, according to the speed designed by the son-in-law, about 4-5 acres of land can be harvested per hour, as for the actual effect, we still need to see the test results for a while." Ling Yu followed the data channel of the design drawing.

"If it can really be like this, it is indeed a divine object, with this divine object, why am I not strong in Da Zhou." Zhou Zhengxiong heard such data, and said happily, if it is harvested according to the current manpower, it is good for a person to harvest two acres of land a day, and it can also tire people half to death.

Soon, the carriage arrived at the Huangzhuang, the Huangzhuang looks no different from the Zhuangzi of the big family, the architectural style is similar, I can't see that it is a royal manor at all, but also, the farm does not need any decoration, the emperor will not come if he has nothing to do, this time Zhou Zhengxiong came in person just to see the harvester.

The big and small stewards and tenants who had already received the news were already waiting at the door, and a large number of people were pressed by the black, and after everyone saw the salute, Zhou Zhengxiong asked the steward to let the tenants disperse, and took Ling Yu and the two into the Huangzhuang.

Zhou Shaobin waited for a long time, and anxiously asked the steward to pick a field that had not yet been harvested to test the harvester, the scope of the Huangzhuang was very large, so big that the carriage could not be finished for a while and a half, but fortunately, there was a field that had not been harvested was relatively close to where they were now, and the steward led everyone to walk over.

When he arrived at the field, looking at the golden grain in the field, Zhou Zhengxiong was in a good mood, it seems that this year's harvest is not bad, Zhou Zhengxiong thought to himself.

Zhou Shaobin hurriedly took out the harvester and motioned for Ling Yu to drive, the emperor was on the side, he didn't dare to make a mistake, and the emperor would not agree to him to test it, not to mention that he didn't know how to use this thing.

Ling Yu nodded, then walked into the driver's seat of the harvester, opened the spirit crystal box, put in the spirit crystal, and then pressed the start button, just listening to the sound of "hum", the harvester started, slowly suspended about five centimeters from the ground, Ling Yu saw this scene, and knew in his heart, it should not be too different from the designed data.

Ling Yu slowly drove the harvester into the field full of mature grain, and drove all the way down, and the rice ears in front were slowly "eaten" by the harvester, and then the rice stalks were spit out from the back of the harvester, and the rice ears entered the preset cloth bags, just like that, ten minutes later, an acre of land was harvested, and Ling Yu let the stunned tenants on the side come forward to collect the rice stalks and tie them, which can be used to burn ash and fertilize the fields when they are cultivated next year.

Zhou Zhengxiong looked at it on the side, his face was full of incredulity, he also knew that psionic technology was very powerful, but he didn't expect it to be so powerful, as Ling Yu said before, science and technology are the primary productive forces, he now believes in this, and his heart attaches great importance to the Academy of Sciences to the extreme, and he has made up his mind to give greater support to the Academy of Sciences in the future, looking at Ling Yu's eyes more softened, this his son-in-law and courtier gave him a great surprise, from life tools to weapons, to the country's fundamental agriculture, no matter which aspect, Ling Yu gave Zhou Zhengxiong a satisfactory answer, how could this make him unhappy in his heart, and now he can only thank God for bringing him such a rebellious talent or son-in-law to Da Zhou. 3a Reading Network

Ling Yu drove the harvester back to the vicinity of Zhou Zhengxiong and the others, then stopped, checked the consumption, and found that the current spiritual energy engine consumption was much lower than when he was then, and it was almost impossible to see how much spirit crystals were consumed in this harvesting an acre of land, which made him feel at ease, if the consumption was too great, then what was the use of this machine? Or not? The result is very good now, and Ling Yu is very lucky.

"Your Majesty, after the test of Wechen, the harvester has fully met the design requirements, and it can reach the level of harvesting 5 acres of land per hour, and the consumption is very low, and Weichen estimates that it is not a problem to harvest 1,000 acres of land with 1 lower grade spirit crystal." Ling Yu respectfully reported that because there were outsiders, he didn't dare to be so casual, after all, Zhou Zhengxiong was the emperor first, and then his father-in-law.

"This is very good, I am very satisfied, Ling Aiqing will teach the steward here how to use it, and then let the Academy of Sciences make every effort to produce harvesters, first try it in Huangzhuang, if the effect is good, it will be promoted nationwide in the coming year." Zhou Zhengxiong waved his hand, he was very appreciative of Ling Yu's occasion, he was very appreciative in his heart, he was really quick-witted and would be in place.

"Brother Ling, teach me first, let me try." Zhou Shaobin saw that Ling Yu finished his report, and hurriedly said.

Zhou Zhengxiong shook his head and smiled and didn't speak, he was helpless about his son's urgency, but fortunately Ling Yu was calm, and he felt a little at ease.

Seeing this, Ling Yu called the stewards to step forward together with Zhou Shaobin and began to tell them in detail how to use the harvester and precautions.

After teaching for a while, Ling Yu didn't say much, let them understand it themselves, and motioned for them to ask him if they didn't understand.

Zhou Shaobin's reaction was very fast, not long after Ling Yu finished speaking, he jumped on the harvester, because Ling Yu had not taken out the spirit crystal just now, Zhou Shaobin directly pressed the start button, and the harvester began to run.

Zhou Shaobin was the time when the novelty was strong, and he drove the harvester to the rice field that had not yet been harvested, although he soon found that no matter how hard he pressed the pedal, the speed of the harvester was still like this, but he did not dislike it, and happily drove the harvester to wreak havoc in the rice field.

Zhou Zhengxiong looked at it for a while, then he didn't look at it anymore, he had already determined the effect, he was relieved, so he beckoned to Ling Yu, and motioned him to accompany him to the pavilion built at zero o'clock next to him to rest, after all, it was in the field, naturally there was no ready-made gazebo, but with an old man like Yucheng who had served the emperor for decades, it was naturally available soon, although it was built at zero o'clock, but it was also very comfortable inside.

"Ling Aiqing, I heard you say that there is another cultivator, I don't know when it can be built?" Zhou Zhengxiong took a sip of tea and asked.

"Your Majesty, the design drawings have been made, but Weichen feels that there is still a long time before spring ploughing, so he is not in a hurry to make samples, and he can't test them now." Ling Yu explained.

"Well, you're right, I'm in a hurry, but I hope you'll build it first, even if it's not suitable for farming now, but it doesn't hurt to test it." Zhou Zhengxiong said.

"Wechen obeys." Since the emperor said it, Ling Yu could only agree, anyway, the design was done, the manufacturing was much simpler, and it could also be tested to roughly what extent.

Soon two hours passed, and Zhou Shaobin had almost had enough, although he was playing, but the work was not pulled down, and the efficiency was still very high, just about the same as Ling Yu's design data, plus what Ling Yu harvested during the test, there were more than ten acres of land harvested.

After Zhou Shaobin stopped the harvester, the steward next to him went up to sort out the harvested rice ears, and then several people took turns to learn how to use it, Zhou Shaobin didn't care about them, and walked straight towards the pavilion.

"Father, the son has measured it, and Brother Ling's design data has been reached." Zhou Shaobin still said unsatisfied, of course, he didn't want to drive a harvester, but wanted to drive a psionic locomotive.

"I saw it, do you still need to say it, the things that Ling Aiqing took out are never bad." Zhou Zhengxiong said with a smile on his face, although there have been a lot of bad things recently, Ling Yu can always give him things that make him feel better from time to time.

"Brother Ling, why don't you take out the psionic locomotive and let your father open his eyes." Zhou Shaobin said to Ling Yu with bad intentions, he was worried about getting on the locomotive.

Before Ling Yu could speak, Zhou Zhengxiong said, "Oh? Is there anything else Ling Aiqing has good things that I haven't seen before? "Because Ling Yu's locomotive has been taken out except for the time when it was first made, it is generally tested at the Academy of Sciences after that, and few people have seen it, and there are not many people who will pay attention to him, so Zhou Zhengxiong did not notice the locomotive either.

"Uh, Your Majesty, this is designed and manufactured by Wechen before, if Your Majesty is interested, Wechen will take Your Majesty to ride." Seeing this, Ling Yu had no choice but to explain honestly, but he was looking for an opportunity to tell Zhou Zhengxiong, after all, he had also been studying large locomotives in the hope of transporting troops, and he was very uncomfortable on the way back to Kaifeng Mansion.

"It's so good, take it out, I also want to see it, this time Ling Aiqing is afraid that she will surprise me again." Zhou Zhengxiong said with a smile.

"Uh, Your Majesty, the impact of this locomotive may be a little big, Weichen suggests that Your Majesty retreat left and right, and then let's go to a place with few people." Ling Yu whispered.

"That's true, it's true." Zhou Shaobin added that he suddenly remembered the possible impact of the locomotive, a little embarrassed, he was too eager, and now he took out the locomotive, if someone has a heart to see it, it is easy to think a lot.

When Zhou Zhengxiong saw the two of them like this, he knew that this was probably another thing that could affect the general trend of the world, so except for Yucheng, Zhou Zhengxiong broke everyone and walked towards a place where there was no one with a few people.
