"It won't be like the four seasons in the future."

"Who knows, if it's really good, before the end of the world, there are basically two seasons of winter and summer, and the summer is long and the winter is short."

Song Yi went back and moved out the sunflowers in the room, the sunflowers originally absorbed heat and glowed, but the sun in winter was too little, so Mr. Liu changed them to a mode that can absorb energy and glow and heat, and can also store the energy that has not been consumed, as long as the temperature is not lower than minus, it will not be released.

For example, now that winter has passed, they can completely put the sunflower outside to absorb light and heat energy and store it, and then take it out and use it in winter, so that they no longer need to input energy to it every day or lay crystal nuclei on the roots.

Others also moved the sunflower out and moved it to a place where there was sunlight outside the pine trees.

Then it is to clean up the clothes and bedding, and the changed clothes should be washed and dried, in order to facilitate the drying of clothes, Ye Lin also asked Li Hua to extend the floor on one side to the outside of the pine tree, so that it can be dried without going to the ground.

Of course, there is a washing machine for washing clothes, or Chen Xia took it out of the secret warehouse last time, there are all kinds of basic electrical appliances in it, and such a big washing machine is more than enough to wash the clothes and bedding of people of their size now.

Fortunately, the current clothes and bedding are stuffed with a special synthetic cotton, which is not easy to deform, even if it is washed directly, it doesn't matter, so everyone washes it all together.

Of course, so many people wash together, there must only be outer clothes and bedding, plus the cleaning agent refined by Bao Yuan, a freshman student, is absolutely clean and hygienic.

What he awakened was the ability of refining and extraction, extracting some purification factors from the Pure Spirit Grass Guinea Fowl, and synthesizing a cleaning agent that can quickly clean up the dirt and sterilize.

With this, there is no need to worry about whether there will be problems with so many people's clothes and bedding being washed together.

Standing on the drying platform, looking at the green outside, Song Yi thought about how to find the materials that could carry the spirit pattern as soon as possible, and she wanted to get out of the flying machine as soon as possible to find her family.

She was not the only one who wanted to think like this, so after Ye Lin entered the spring, she arranged for someone to go outside to explore and collect all the plant mineral samples, and brought them back for Zhou Hui to identify.

But the progress is not smooth, although I have found a lot of novel plants that I have never seen before, and many of them are useful, such as vegetables with the effect of weight loss and fat loss, fruits with whitening effect, and flowers that can be as light as a swallow for an hour, but there is no material that can carry the spirit pattern that Song Yi wants.

Although there are many mutated plants after the end of the world, there are not many that are really directly useful, just like the ones brought back before, which need to be domesticated before they can be used by humans.

Song Yi also thought about whether it was convenient to make paper, but unfortunately, a lot of paper was made, but none of them could carry the spirit pattern.

After several studies, Song Yi found that it was because of the uneven energy distribution of these things, and every time he drew the spirit pattern, he would be interrupted because of those uneven energy, and eventually failed or even exploded.

After discovering this, she tried to spread the energy evenly among them, but she never succeeded, and there will always be some uneven parts of the material due to various reasons.

In the end, she felt that she could only find suitable materials, just like the cultivation realm in the novel, not all materials could be used to make rune paper, so she went out with the exploration team and opened her eyes every day to find suitable materials.

This is undoubtedly harmful to her eyes, three days later, her eyes began to dry, and then she even shed blood and tears, fortunately Zhong Li treated it in time, Zhou Wan ran over after hearing the news: "You don't want to die." ”

"......" Song Yi closed her eyes, and her eyes were wrapped with gauze, which Zhong Li forcibly wrapped for her, saying that although she had temporarily treated her injuries, her eyes were a delicate part and needed a good rest.

The gauze is filled with a kind of sap that is good for the eyes, which can treat myopia, eye fatigue and other damages, and even retinal detachment can be replaced by the leaf membrane of the eye.

"I know you're in a hurry to go back, none of us are in a hurry, everyone's relatives aren't around, but no matter how anxious you are, you can't ignore your body." Zhou Wan knew why Song Yi was working so hard, and the others were working hard for this.

Song Yi is anxious to find materials that can carry the spirit pattern, Li Hua is also cooperating with Teacher Qiao to make various mini parts, wanting to make a flying machine that can be used in the last days, and everyone else is also looking for various materials that can be used, and everyone wants to find a way to return to the city.

But some things are really not in a hurry, if they are all like Song Yi, what is the use of abolishing themselves before they go back.

"I see." Song Yi finally spoke, she also knew that she was too anxious, it had been 5 months since the end of the world, and she had broken off contact for 4 months, and now it was finally spring, and there was no heavy snow to cover the mountain, she naturally wanted to go back as soon as possible, but she forgot that if she wanted to hurry, she would not reach.

Because he almost blinded himself and was scolded by Zhou Wan again, Song Yi finally stopped, no longer in a hurry for quick success, and waited until the gauze was removed, although he still followed the exploration team out, he no longer kept opening his eyes.

"New variety, not entered." After scanning a plant with a bracelet, the voice is broadcast.

"I haven't seen it." The people who heard the announcement immediately came up to collect, and the collected plants were brought back to Zhou Hui for identification, and if they were useful, they would cultivate and plant, so when they collected, they usually dug the whole plant with soil.

Song Yi was about to turn off the light screen and stepped forward to help, and then noticed something, she didn't know when a signal appeared on the bracelet, she was shocked and happy, and immediately contacted her parents.

The connection signal on the light screen has been spinning in circles, it seems that the signal is very bad, and it has not been successful for a long time, and Song Yi's mood has been a little numb from surprise to anxiety in the end.

"Song Yi, what's wrong with you?" The others found that Song Yi was standing there motionless, it was a little strange, usually Song Yi had already stepped forward to help, after all, digging up these plants with roots buried deep in the ground was still what she and the soil powerhouses were better at.

"There is a signal, but the signal seems to be very poor, I saw the signal and contacted my parents as soon as possible, but there was no communication for 5 minutes." Song Yi didn't hide it either, and replied.

"Really." When the others heard this, they hurriedly turned on the light screen, and sure enough, they saw the signal that was only one bar, and they were immediately surprised, and they also contacted their parents one after another, and naturally they were as unsuccessful as Song Yi.

And after everyone started to contact, her signal communication was also disconnected, indicating that there was no signal and could not be contacted, Song Yi frowned, and tried again without giving up.
