The sudden idea is stored in the to-do options in the mind of Jiang Yan, Jiang Yan must do the matter of raising chickens, the high yield of local chickens in the countryside is scary, an adult native chicken can lay an egg in three or two days, if the family raises ten, it can't be eaten.

"You can also raise some rabbits, rabbits reproduce quickly, and the dish of spicy rabbit is also good."

"You can also row a pond and raise some grass carp brought back by Zhao Dabai, and you won't worry about fish eating when you breed."

"Then I bring a cow back and drink milk every day in the morning."

Counting his fingers, Jiang Yan's thoughts gradually let go, there were more and more thoughts in his heart, and the to-do list was getting fuller and fuller.

The conjecture lasted for a while, Jiang Yan came back to his senses, and looking at the sun that had not yet set in the sky, Jiang Yan planned to go out for a walk.

"Hey, I'm going out for a walk, are you going or not." Turning around, Jiang Yan looked at Gao Chou on the cement platform and opened his mouth to invite.

Hearing this, Gao Chou pondered for a moment, then put down the book in his hand and struggled to get up from the seat.

"Yes."

Realizing that Gao Chou was going out with him, Jiang Yan returned to the storage room and pinned the hidden pistol to his waist, Jiang Yan also carried his bow and arrows on his back, as well as the dagger he had captured from Gao Chou before.

The disappearance of human civilization has brought nature back to the highlands, and wild animals have gradually spread, which makes Jiang Yan can't help but take protective measures.

After all, Zhao Dabai, the black bear, took the initiative to break into the door when he knew that he was at home.

Fully armed, Jiang Yan walked out of the gate with Gao Chou, who found a stick from the big tree he had cut down earlier and used it as a crutch, and it looked like it had been carefully repaired by Gao Chou.

Along the cement road, Jiang Yan walked towards the west, where there were not only more farmhouses, but also the village detachment he had seen earlier.

"This is the village detachment of Shengjia Village, and originally there would have been movies in this place." Walking into the square of the village detachment with high sorrow, Jiang Yan pointed to the basketball hoop on the side and said.

When he was a child, Jiang Yan often played with his classmates here, sometimes ran into weekends to watch movies, and met some elders who walked after dinner.

"This place is pretty big." Gao Chou glanced at his surroundings and was habitually cautious.

As if reminiscing about his childhood, Jiang Yan sat on the surrounding fitness equipment for a while, the wide square made the fleeing Gao Chou a little uncomfortable, looking at the cramped Gao Chou beside him, Jiang Yan took the latter and left the village detachment.

"Further west, is where I went to elementary school, the school is called Shengjia Primary School, and we will go in and have a look later, and maybe we can find some rare things like chalk."

Along the cement road, Jiang Yan and the two walked slowly, and after walking for five minutes, Jiang Yan rushed to the Shengjia Primary School described.

From a distance, it was only a five-story teaching building, and the area of the front yard was even smaller than Jiang Yan's backyard, but after passing through the teaching building, Gao Chou suddenly found that the playground was at the back of the teaching building.

The rusty door lock of the side door was kicked and shattered by Jiang Yan, pulling Gao Sorrow, Jiang Yan cautiously walked into the Shengjia Primary School.

"When I was young, I thought this school was very big, but now when I look at it, it's only five stories high."

The dim environment made Jiang Yan a little scared, and the dampness of disrepair made the entire teaching building permeate with a choking musty smell.

The high sorrow on the side seems to have experienced these often, not only does not have any intentions, but even takes the initiative to look around.

"The first level was the first and second grades, when there were so few students and there was only one class in each grade, so I didn't know what a class meant until I went to junior high school."

Maybe because of fear, Jiang Yan had some broken thoughts at the moment, recalling everything that happened when he was a child, Jiang Yan described the story that Gao Chou couldn't understand at all.

Gao Chou on the side didn't hear Jiang Yan's words clearly, and strode towards the class, the neat desks were quietly placed there as if they had traveled through time and space, and the blackboard on the wall still wrote the knowledge taught back then.

"Chalk, is this it?"

Picking up the chalk box on the podium, Gao Chou turned to look at Jiang Yan.

Hearing Gao Chou's words, Jiang Yan hurriedly ran over, looked at the chalk in Gao Chou's hand, and nodded affirmatively.

"What's the use of this thing?"

He took out a piece of chalk and looked at it suspiciously, he didn't know what this thing was for, everything in front of him was extremely new to him.

"This thing is mainly made of calcium carbonate, also called gypsum, which is of little use to us now, but after a while, it can be used to order tofu."

Pulling out a piece of chalk, Jiang Yan wrote his name on the blackboard, and then put it back in the pen case.

Jiang Yan's description Gao Chou didn't understand, but when he heard that he could make tofu, Gao Chou carefully stuffed the chalk box into his arms as if he were a baby, and collected all the scattered chalk ashes.

"It's not like that, there should be a lot of chalk stored in the school, and it's full."

Seeing Gao Chou's actions, Jiang Yan couldn't help laughing, opened his mouth to explain, and then walked upstairs with Gao Chou.

"The second floor is for the senior grades, the third floor is for the higher ages, the fifth floor is the computer room and the principal's room, and now the fourth floor is the teachers' offices and storage rooms, and there may be treasures in it."

With high sorrow, Jiang Yan climbed several steps in a row, panting, Jiang Yan pointed to the sign on the door frame and explained to Gao Chou on the side.

Hearing this, Gao Chou instantly walked to a door, gently pushed, and the wooden door opened.

There were messy papers on the neat desk, and following Gao Chou into the door, Jiang Yan looked at the offices of the previous teachers with a complicated expression.

"Is there anything you need here?"

After rummaging around, Gao Chou didn't find anything useful, turned around and asked Jiang Yan on the side.

"No, try another one."

Hearing this, Gao Chou opened another door, and this time, the content inside was completely different.

The spacious room is crowded with all kinds of things, balls for various sports, skipping ropes, and a lot of teaching equipment.

"This..."

Seeing the chaotic scene in front of him, Gao Chou's mind instantly became confused.

"Take this ball away and play with Zhao Dabai."

Following behind Gao Chou, Jiang Yan pointed to a basketball and motioned for Gao Chou to take it away.

Scanning the clutter around him, Jiang Yan kept looking for something that could be used, which was like a treasure trove for Jiang Yan.

"These pumps can be converted into blowers."

"I also have these magnifying glasses, although I don't know what they are for."

Picking up a bag casually, Jiang Yan was filled with all kinds of things, although she didn't know what it was for, but for Jiang Yan now, as long as it was a working object, she wanted to bring it back.

"Jiang Yan, I found this, what is this thing for?"

Jiang Yan, who was immersed in hard work, heard Gao Chou's words, instantly raised his head, saw the object under Gao Chou's feet, and immediately squinted his eyes and stepped forward.

"This is. Dynamo! ”

Holding the iron bump on the ground, Jiang Yan looked at the shocked opening for a moment, the generator is no stranger to Jiang Yan, there is one in the basement, but the one in his hand is completely different from the one in the basement, because he is an electromagnetic induction generator.

Wind power and water power can make it generate electricity, and the structure is not too difficult, if you understand the principle a little, even if you damage the ginger smoke, you can repair it!

"This! But it's so important! ”
