A brief moment of dizziness, then opening of the eyes, the sun shines on your face.

I returned to the place before the crossing, a clearing behind the courtyard. When you go back to the parallel world, if you don't select a map, it will default to the location you started from. Of course, you can also choose a map, but now Zhu Changyuan is not familiar with the map of the Ming Dynasty, and he can't choose it.

I just came back and took a look at the clothes on my body, and sure enough, I changed back to my original costume, and my hair has become long, which is really strange.

As for his mobile phone, it is gone, looking for it and not finding it, Zhu Changyuan wondered for a while, and said that it should be because he didn't put things in the car, and he must remember to put his mobile phone in the car next time he comes, in case he sees the emperor long live the emperor one day, no, even if he sees Wu Sangui, the chief soldier of Shanhaiguan, he can take a photo, right?

Forget it, throw away these things, Zhu Changyuan drove the carriage all the way to the front of the courtyard, and said to the people of the old Wang family who were plowing, "Come here, move fertilizer." ”

Everyone gathered around curiously, looking at the carriage and the maroon horse, they were all surprised, and Wang Laohan asked: "Little prince, your carriage is a little strange, the wheels are like iron lumps." ”

Zhu Changyuan saw that it was a rubber wheel, and he probably couldn't explain it clearly, so he said nonsense: "This is not an iron lump, it is wood, a different wood." He quickly changed the topic and said: "Move the fertilizer off the top, do it, quickly." ”

"Fertilizer?" Wang Hu waited and looked at the truckload of compound fertilizer piled up like a mountain, and asked, "What is fertilizer?" ”

"It's big, go and move it, where is so much nonsense." After Zhu Changyuan finished speaking, he kicked Wang Hu's ass lightly. Wang Hu covered his buttocks and laughed, jumped into the car, and began to move fertilizer down.

Eighty bags of fertilizer, everyone easily got it, and even Zhu Changning on the side came over to help carry it.

After moving those things, Zhu Changyuan told everyone the fertilization method of chemical fertilizer, which is nothing more than spreading evenly in the ground, and the key is to control the amount.

"Okay, tomorrow I have to buy a little back, these can only be used for eighty acres of land, by the way, tomorrow I will transport the seeds together, don't rush to plant first, wait for me to come back."

After arranging everyone, he was not idle, and hurriedly ran to the room to close the door, as for the carriage outside, Zhu Changyuan did not take it away for the time being, otherwise it would be too terrifying and not good to scare them.

Stretched out his hand and clicked on the system interface, looking at the remaining contribution value on it, it was only 60,000, and he just returned to modern times to buy fertilizer, and it took a full hour, and the contribution value of 30,000 was gone.

However, Zhu Changyuan opened the system interface this time mainly not to see the balance of contribution points, but he found that since the last system upgrade, there are many more things on the interface.

It's in the inventory, and in addition to showing the cart, there's also a skill book slot.

Zhu Changyuan stretched out his hand to open the skill book, and in the next drop-down menu, the category was displayed. There are social sciences and natural sciences.

Reaching out to open the natural science category, I found that there are more detailed classifications below, such as construction, electricity, machinery, agriculture, ships, and so on.

Zhu Changyuan casually clicked on the mechanical class, and there was a book that exuded a golden light and looked a little quaint, which looked like a thick one, with seven typing words on it, and a line of English annotation below.

"This is a service, and foreigners can also use this thing emotionally!" Zhu Changyuan sighed with emotion, pointed his finger at the skill book, and displayed "Use contribution points in exchange for this basic skill book"

The next one is "yes" and one is "no".

"Yes"

"In exchange for this skill book, you need to consume 10,000 contribution points, is it in exchange?"

"Yes"

"Ding ......" At the moment when Zhu Changyuan's finger pointed yes, a crisp mechanical sound sounded, and immediately, the golden book suddenly emitted light and jumped out of the skill bar.

Zhu Changyuan held it in his hand, it looked heavy, and he turned it hard, but he didn't turn the page. Xin said: "It's so strange, I don't know how this thing is used?" ”

As soon as he finished muttering, a mechanical voice came from the system: "How to use ......"

Zhu Changyuan and the other system introduced me, smiled, picked up the book and patted it on his head, and suddenly, the book turned into a little golden light, and it slowly floated into his mind.

"Excavator use and maintenance."

"The use and skills of motor graders and general maintenance methods."

"Methods of maintenance and upkeep of tractors." ……

Anyway, all kinds of mechanical books went through in his mind, and then Zhu Changyuan magically found that he had mastered all of this knowledge, as if they originally existed in his mind.

This? It's amazing, isn't it?

Looking at the system interface where I took out the book before, the book that I had just taken away was displayed in the inventory again, and I could continue to exchange it. But Zhu Changyuan had already exchanged and mastered this knowledge, and did not exchange it again.

Open other subject classes,It's the same.,The following skill book exchange costs 10,000 contribution points.,Because I don't know what is useful to myself.,There's no blind exchange.,Anyway, this thing learns quickly.,As long as there is a contribution value.,It's completely possible to sharpen the gun in battle.。

As soon as I finished studying the system, I suddenly heard another "ding" sound in my head.

Then, a mechanical voice came: "The host changes the parallel world, the fertilizer improves the land to complete one acre, and the reward contribution value is one thousand points." Tick tick. ”

Wow, there's a bonus to that, too.

Or 1,000 points, doesn't that mean that after all the 100 acres of land here are improved, they will get 100,000 contribution points?

Zhu Changyuan almost jumped out of bed excitedly.

More and more chemical fertilizer was sprinkled in the ground, and in one day, all the women and children who were idle and dared to go into battle went into battle, and they actually fertilized all 80 acres of land. This is not surprising to Zhu Changyuan at all, after all, it is enough to sprinkle it on the ground.

80,000 contribution value is in hand, easy to get.

The next day, at the same time, Zhu Changyuan traveled back to the modern world from the parallel world in almost the same way and place, at the intersection of Fengchan Road and Minguang Road in Nandu, and the agricultural material station.

This time, whether it was the boss or Zhu Changyuan, they were much more skilled, and they loaded the compound fertilizer on the car early.

Zhu Changyuan used the boss's charger to charge his mobile phone again, and at this time, Liu Guang's phone called, and said, "Brother, I can't get through to your phone." Let me tell you a big thing, that thing of yours, my brother-in-law said it was true, it was worth more than a million, but your father picked it up this time. ”

"Nonsense, I said it was true, I almost let your kid break me."

"Oh, sin and sin!" Liu Guang said hehehe, and said: "My brother-in-law said that it would be a pity to sell it like this, if you have to find a friend to enter the auction house for auction, then the price will be very high, your thing is from the Chenghua period, and it is worth two million." Brother, are you sure you sell this bottle? ”

"Sell, sell, sell, more than 800,000 yuan, I will give you 30% of what you earn."

"Really, brother, I love you to death."

"Don't disgust me, don't call Lao Tzu's big intestine in the future. Hey, by the way, don't let your brother-in-law hack our money. Zhu Changyuan advised.

"He dares! I asked my sister to break his dog's leg. Damn, who dares to black the big intestine brother's money in front of me. ”

Yes, what I said just now is equivalent to not saying it, and the large intestine comes out again.

Just as I was about to hang up the phone, I heard a female voice say, "Whose dog's leg is being interrupted?" ”

I heard Liu Guang whisper again: "Ah, old sister! No, no, why did you come all of a sudden. ”

Zhu Changyuan smiled at the corner of his mouth and hung up the phone. He also bought seeds of high-quality winter wheat, which is said to have been developed by a professor at the Agricultural University, and bought ten bags of one hundred acres of land, ten catties per acre, and snakeskin bags.

Seeing that there is still a lot of space on the car, and things can be stacked, Zhu Changyuan walked around the agricultural materials station, saw what diesel generators, water pumps, water pipes, and bought hundreds of meters of wires, vices, wires, etc., and bought a plastic drum of diesel, which was fifty or sixty liters, put it on the carriage casually, paid the money, and drove the horse out of the agricultural materials station.

Now that you have the basics of mechanics, it's still pediatric to play with a generator.

Suddenly I thought of something, took out the mobile phone from the pocket of my clothes, put it in the car, but I didn't expect the system to prompt immediately: "Prompt, prompt, put in something too high a degree of technology, the system level is too low, it can't be carried, it can't be carried, please clear it." ”

There is also such a thing, is the degree of technology of this mobile phone higher than that of diesel engines? Zhu Changyuan thought about it carefully, it is really possible, for example, he can easily understand all kinds of basic mechanical principles, but there is a chip circuit or something in the mobile phone, it is estimated that it is even more difficult, and it is estimated that it is really impossible to eat a book.

"Alas, forget it, Emperor Chongzhen, Wu Sangui, brother can't stand you, I can't leave your photos! I don't know if the camera will be able to be shipped, so I'll talk about it next time. ”

When I walked to an intersection where no one was around, it was dark in front of me, and I instantly returned to a parallel world.
