Hong Yan suddenly realized, after reading the introduction of mechanical insects before, mechanical insects can devour any metal to increase the population, and the more mechanical insects, the faster the progress will be.

However, as for where to get metal, he is a little nerve-wracking, and spending a lot of money to buy metal is not realistic for him now, so he can only think about free metal. Although metal can be found everywhere in daily life, such as telephone poles, cars on the road, and steel bars in buildings, it does not mean that you can devour it if you want to. Otherwise, something disappears out of thin air and will definitely cause unnecessary trouble if it is discovered.

After thinking about it, I suddenly remembered that there was a scrapped tractor lying on the side of the road at the bottom of the mountain.

Hong Yan immediately extracted a part of the mechanical insects that had submerged into the trunk of the lychee tree and went straight to the bottom of the mountain.

"The number of units of work has been reduced, and the completion time is expected to take five hours and ten minutes." There was a cold hint from the AI in my head.

Hong Yan really rolled his eyes and gave it a roll, but there was no way, it was important to modify the lychee gene, and it was also important to expand the number of mechanical insects, so let's do it on both sides at the same time.

Trotted all the way to the tractor, which was overgrown with weeds. Peeling aside the grass to take a closer look, the diesel engine head had been removed, and the fuselage was rusty and covered with a thick layer of mud.

"Wouldn't it be diarrhea if such a metal mechanical insect was devoured?" Hong Yan couldn't help but tease when he saw the situation of the tractor.

The mechanical bug was speechless.

Adhering to the principle that no matter how small a mosquito's legs are, they are also meat, Hong Yan threw the mechanical worm on his arm onto the tractor. I saw a small lump of something like silver-gray liquid flying out and directly attached to the surface of the tractor.

For a moment, Hong Yan seemed to hear the cheerful chewing sound of mechanical insects.

Because the number of mechanical bugs is so small, the progress of devouring the tractor is not too obvious. Hong Yan observed for half an hour, and the tractor was gnawing on a piece, but the number of mechanical insects did not increase much. After asking the AI, I learned that the ratio of metal to mechanical worms is not 1:1, and different ratios are converted according to different metals. According to the most basic iron, one ton of iron can transform one kilogram of mechanical worms.

Seeing that the time was not early, it would take some time for the mechanical insects to devour the tractor, and it was not a matter of waiting on the side, so Hong Yan decided to go back to sleep first and come back early tomorrow morning to have a look.

At five o'clock the next morning, Hong Yan came to the location of the tractor, and the rural people woke up early, and if they got up late, they were afraid that their families would find out that he had no arms.

At this point, the tractor was gone, leaving only a small pool of silver-gray liquid on the ground, needless to say, these must be mechanical bugs. Compared to last night, the number has indeed increased today.

The mechanical insect sensed Hong Yan, and like a tadpole finding its mother, it quickly crawled towards him and sank into his right arm. Although it devoured the tractor for a night, it was only enough to generate half an arm.

But it didn't matter, he just had the robot simulate the entire arm, which was hollow but didn't affect the use of the arm.

Then he walked back to his lychee grove, where the genetics of the lychee tree had been modified last night, and the mechanical insect was working on another lychee tree.

For genetically modified lychees, the difference between them and other unmodified genes can really be seen with the naked eye alone, and the most intuitive difference is that the lychee fruit is slightly larger. Take a look at the parameters again, and all of them are up to the values set last night.

Since the gene modification works, let the robots continue their work. However, there is still half a month before the first batch of lychees on the market, and he needs more mechanical insects to speed up the progress.

If you want to expand the number of robotic bugs, the question comes back to where to get the metal. It used to be a ghost eating a tractor because it had been abandoned for so long that no one would notice.

While thinking about where there was scrap metal, I went down the mountain.

When I got home, it was already more than eight o'clock in the morning, and when I entered the door, I happened to meet Hong's father who was about to go out.

"Going out early in the morning?" Father Hong saw Hong Yan coming back and asked with concern

"Go for a run, where are you going?" Hong Yan casually made up an excuse

"Your uncle fell and injured his leg two days ago, and now he is living in the county hospital, I'll go over and take a look." Father Hong replied casually

Hong Yan's uncle is a veteran who came out of a war, and the various scars on his body tell the bravery of those years. After retiring with glory, he was assigned to work in a factory with a national brand. Uncle Tai has never married in his life, has no children and no daughters, but he has a very high rank in these ten miles and eight towns. When there was a major natural disaster, he took the villagers to fight bandits, and he used a mountain knife to deter the surrounding Xiaoxiao.

After the 80s, Huaxia took the route of market economy, and many factories could not receive any orders for various reasons, and the factories went into decline. The people in the factory are gone, but Uncle Tai still stays in the factory as a janitor, receiving the minimum basic wage every month, which can be regarded as a retirement in his old age.

Although he was alone in the factory, he was often visited by people and left behind all kinds of household items. Moreover, Uncle Tai was very kind to the juniors in his later years, and often took all kinds of candy and biscuits to distribute to any child he saw, Hong Yan was one of them.

Ha, when I mentioned my uncle Hong Yan, I slapped my head, how did I forget him.

Uncle Tai's factory is a steel mill, which is a product of the era of great steelmaking. In the past, under the environment of the great era, whether it was useful or not, it was necessary to build a steel plant first, so under the care of some leaders in the city, the Hongqi Iron and Steel Plant was quickly built.

This steel factory Hong Yan often visited when he was a child, because it covers an estimated area of 2 square kilometers, and various buildings in it are intricate, making it a good place to explore hide-and-seek.

In Hong Yan's memory, there were not only all kinds of machines in the factory, but also piles of discarded scraps. And it's been abandoned for more than 20 years, so it shouldn't matter if you empty it, right?

Now that he has a goal, no matter if Hong Mu shouts behind him to eat breakfast first and then go out, Hong Yan still doesn't look back and quickly rushes towards the Hongqi Iron and Steel Factory.

The steel mill is not far from Hong Yan's home, because it has been abandoned for many years, and a cement road in disrepair connects to the county road outside. According to Hong Yan's physical strength now, he can reach it by running for half an hour.

Coming to the factory gate, the rusty Hongqi Iron and Steel Plant on the metal arch shows the current decline.

The factory is surrounded by a stone fence with broken beer bottle glass slag and tall birch trees waving in the wind. Outside the fence is a dirt road flooded with weeds, and among the weeds there are many hibiscus blooming bright flowers.

Next to the gate is the legendary communication room, which is the main living place of the uncle. The area of the communication room is still relatively large, divided into two rooms before and after, one in the back, the front is the living room, and the kitchen is in the storage room next to the communication room.

At this time, Uncle Tai was not fair, and Hong Yan flew directly into the factory.

With the memory of the past, there is more metal in the factory than expected. He hadn't paid attention to any of this before, but today he was ecstatic to look for the actual metal stock in detail. Not only are there countless large and small machines, but also a lot of leftovers and ores, and most importantly, there are a large number of finished products that have been smelted and backlogged in the warehouse.

Hong Yan directly found a warehouse, waved his right hand, and shouted happily: "Go, my mechanical insects, don't give me face, devour them to your heart's content." ”

Robotic Bug: "......"
