Kagawa sat at the door of the tent in a daze, she looked at the open space of the camp facing the tent, more than 30 students came and went, and it only took less than two days to trample the lawn of this open space a little bare, and the class leader frowned.

"Are we going to trample on this garrison so that not a single grass can grow?" The squad leader came to the Kagawa tent to take a sip of fruit milk and drink, and accidentally said this worry in his heart.

"The weeds are not so delicate, now you are trampling this place into yellow earth, and this time next year it will be full of weeds." Kagawa replied casually.

"Huh? Is that so? The squad leader was interested, and Fu Chengkai and Mandy, who happened to come to find the squad leader, were also interested when they heard this.

"I don't remember the principle or anything," this is the truth, she only remembers a rough idea of geography knowledge in high school, and the detailed theory cannot be said unless Geegle is opened on the spot (of course, this is impossible), "As far as the laws of nature are concerned, this place is close to the water source, and our boat group is basically a subtropical or temperate climate...... In short, it is not very hot, under these two conditions, the bald grassland that we trample on has the moisture of groundwater, has a suitable temperature, plus the grass roots buried in the ground, I am afraid that it will not take a year, and it will have returned to a green appearance by the summer. ”

"I seem to have seen this phenomenon in the history library of the space-time network, saying that it is a necessary condition for plant growth or something......" Fu Chengkai frowned and kept thinking about the materials that he had only read roughly once, but obviously, modern teenagers still can't do it and never forget it, and finally gave up his memories, he looked at Kagawa with admiration, "I didn't expect Kagawa-san, you not only know a lot about ancient food production, but also are interested in old ancient books such as ancient plant growth records?" ”

"This is not an antique," Kagawa shook the ginger blossom he was playing with, "The cultivation and growth of plants is also closely related to survival for us modern people, if plants cannot grow normally according to the laws of nature, then the nature reserve of the main ship will suffer a catastrophe, and the ecological circle will collapse, then we will become the only creatures on the main ship that can survive by relying on modern technology." ”

Kagawa looked at the three of them, the squad leader frowned slightly after hearing this, put his hand on his chin and was thinking about something, and the other two still had a blank look on their faces, and she sighed secretly in her heart.

Modern people have been accustomed to the way of living away from other ecosystems, there are no animals and insects in the city, and occasionally you can see the trees, grasses, wildflowers, etc. in parks and roadsides, and the development of modern technology has completely realized the communication between people to meet and talk anytime and anywhere, voice communication, video communication, and even holograms, the loneliness of leaving home can be eliminated, and people will not pin this loneliness on other animals and plants, and there will be no habit of raising animals or cultivating flowers and plants. Therefore, most modern people are very unfamiliar with the growth of animals and plants in nature reserves or common sense, and lack a certain common sense of trees, flowers and plants, or even wild grasses that can be seen everywhere.

"And we serve as a staple food...... Well...... The cultivation of rice and wheat, which are the staple foods of liquid food and solid food, was also inseparable from the study of this kind of environment in ancient times, and people would have starved to death in ancient times without studying these things. Kagawa took a sip of fruit milk and moistened his throat, "Then there is no such convenient thing as producing escort ships to think about how to standardize farms, crop cultivation or something, suddenly a natural disaster or war and war, all the fields are destroyed, and you have to start from scratch." ”

"The ancients were really hard." "I can't imagine growing crops without being able to control the temperature and humidity. ”

"These are the kinds of lives that the ancients were accustomed to." Kagawa turned the flower in his hand, "Plants are more fragile than people, and if we pull them lightly, they may break, but plants also have the strongest survival instinct in nature, even if this place is scorched by fire, as long as the soil and water are still there, then they can continue to survive......"

"In other words, how are we going to toss this meadow for the next five days?" The squad leader, who had been silent, suddenly spoke.

“………… Well. "Kagawa: Did you dare to worry about this just now?

Outside the camp, Aino took Ouyang Yating and Nancy for a walk in the nearby forest, yesterday's walk was cut off halfway because of digging up ginger, and now the three of them are thinking about the walk that they didn't finish yesterday.

"It's been a long time since the three of us came out for a walk together, when was the last time we got together like this?" Nancy stretched, lazily looking at the other two with expressionless faces.

"Didn't you just walk in the park in junior high school when you graduated from junior high school? And after graduation, I also got together when the family held a party, and it was only more than two months. Ouyang Yating glanced at her expressionlessly.

"It's only been two months? But it always feels like half a year has passed...... Never mind. Nancy looked at the two with a smile on her face and smiled, "What's going on?" Club life in less than a week? Are there any special catches? ”

"The club hasn't officially started to operate yet, how can you talk about your feelings......" Ouyang Yating touched her chin, "...... However, there are still a lot of surprises. After all, she never thought of digging up plant rhizomes by herself, and thinking of this, Ouyang Yating couldn't help but show a helpless wry smile.

However, Nancy saw a little ease in Fa Xiao's smile, and she couldn't help laughing when she saw it, and then suddenly remembered that there was a persecuted person next to her who had been silent from the beginning...... Ahem, gentleman, she raised her eyebrows and asked, "What about you?" Aino? ”

"Why don't you go back and ask Lianggong, how long have I been transferred in?" Aino looked at her with a frown.

"I don't have any thoughts about club activities, but I always have some thoughts about the president or other members, right?" Nancy looked at him expectantly, "Tell me, after all, I've 'confessed' to others, haven't they?" ”

I specially accented the two words of confession.

When it comes to this black history, Aino's cool expression can't hold back, and the corners of his eyes keep twitching and looking at Fa Xiao, who doesn't think it's a big deal: "Can't you not mention this matter?" ”

"You don't want to talk? Okay, then I'll go and talk to Uncle Dowling~" Nancy walked ahead with a grin, leaving the two behind.

Ouyang Yating looked at Aino: "I'm afraid this matter is not going to become your handle for the rest of your life." ”

“…… Say less. "Aino: The eyes are dead, don't disturb.
