"Let's go home." Grandma Song pulled Song Yi into the house.
"Yiyi, where is your luggage?" Grandpa Zhou, who was lagging behind, originally planned to help with the luggage, but found that Song Yi had nothing in his hands except a pair of strange wings on his back, so he asked.
"The luggage is all in here." Song Yi picked up the satchel-style space bag on her waist, "This is the space bag. There are 6 cubic meters of space in it, and everything is packed in it."
Of course, this space is not her largest space. Although people have become smaller, plants have become larger. Song Yi has stored a lot of mutant plants and seeds, which naturally fills a lot of space.
"Space bag? Is it a storage space?" Grandma Zhou asked curiously after hearing her words.
"Yes, we have developed a magic circle that attaches special powers to items. This is the storage space where we built a space expansion magic circle." Song Yi nodded.
"This is similar to your grandpa's ability." Grandpa Song said.
"Hey, what is grandpa's superpower?" Song Yi was a little curious. When she asked before, grandpa didn't have superpowers yet.
"In your father's words, it's enchantment." Grandma Song said.
"That's indeed very similar." Song Yi knew that his father had awakened the detection ability, which was similar to the identification technique but a little different.
While talking, they entered the house and sat on the sofa in the living room. "How has the situation been at home in the past six months or so?" Song Yi asked after sitting down.
"The family is very good, everyone is alive." Grandpa Song said. For him, when encountering the apocalypse, having everyone in the family alive is the best thing.
Song Yi knew from the words of several elderly people that the two families now lived next to each other. Both her parents and uncles were working, and her younger siblings were also busy, so there were only four elderly people in the family.
"They should be back for dinner after a while." Grandma Song looked at the time and said. After talking about the situation at home, she asked about Song Yi: "What about you, how did you get here in the past six months?"
"I..." Song Yi talked about his experiences in the past six months. He gathered all the teachers and students of the school to build a temporary base after the apocalypse. How to find a secret warehouse to obtain controllable nuclear fusion fuel to survive the cold winter. Including the matter of them sentencing He Xiao together.
"I brought back a lot of good things," Song Yi opened his space bag and took out things one by one:
"These are flying wings. You can fly by wearing them on your back. I brought a few for everyone. These are guinea fowls and their eggs. Each of these space bags also has one for each person."
"These are the seeds of mutated sweet potato, sunflower, oil fruit, health fruit, invisible grass, pure spirit grass, purifying grass, rice fruit, repair flower, wine grass, flying flower, bright eye grass, substitute grass, and bloody grass. There is also this, a flying skateboard modified with a magic circle. This is a suit I specially customized for Xie Xueyi, with a constant-temperature magic circle added to it. With this, you don’t have to worry about the temperature. Everyone in the family has two sets."
Then she introduced the uses of those seeds in detail, and Grandpa Song's eyes almost shone. Before he retired, he was a professor at the Institute of Botany. Song Yi knew how to learn this because he was responsible for it.
"Are these mutant plants improved by you?" Grandpa Song knows how ferocious mutant plants are today. Even those that are identified as useful are basically aggressive.
"Yes, they are all improved and domesticated." Song Yi nodded.
Song Yi also specially asked Teacher Liu to domesticate and improve the substitute grass and bloody grass. The substitute grass is originally a parasitic plant, which will parasitize the prey and slowly turn into the appearance of the prey. The bloody grass will actively attack and inject toxins.
After domestication, the substitute grass retains its original characteristics, but no longer has the ability to be parasitic. The bloody grass is still highly poisonous, but it no longer actively attacks.
"This ability is great, why don't I have such ability?" Grandpa Song said regretfully after hearing about the domestication process.
"Grandpa, do you want to try this? This is a marrow-cleansing potion. It can cleanse the marrow and remove radiation contamination from the body." Song Yi took out a few bottles of potion and said.
Although the marrow cleansing medicine was extremely painful after use, Song Yi still took it out. Her grandparents were older, and the radiation pollution in their bodies was much more serious than that of young people like them.
Before the end of the world, although everyone tried their best to wear clothes that could isolate radiation, it was impossible to wear clothes all the time, and there was also radiation contamination in food, which was unavoidable. Therefore, everyone has radiation contamination on their body, and they need to be treated regularly. A radiation-excluding treatment.
However, the effect is limited. As we age, radiation pollution will precipitate more and become more difficult to remove. Even if humans desperately research medicines to remove radiation pollution, it will be useless.
It has been three hundred years, but the average life span of human beings has only reached 81 years. It is because of radiation pollution. Many scientists have shown that without the damage of radiation pollution, the maximum life span of humans can be increased to 150 years, and the average life span can reach at least 130 years. .
Although the superpower seems to have strengthened the bodies of some grandparents, the effect is not great. The grandfather who is only 76 years old looks older than the 70-year-old man 300 years ago. She knows that these are the effects of pollution.
In fact, humans have now minimized the harm of radiation to the human body. It may be that humans have also developed some immunity over such a long time, so it is only life span that is affected, not various diseases. It is said that radiation pollution was just serious in the beginning. There will be people deformed by radiation every day in the world.
Even so, radiation contamination should not be underestimated, so she specially made a lot of marrow cleaning potions before returning, just to let her family use them as soon as possible.
"Can radiation pollution be removed?" Grandpa Zhou immediately raised his head, "Is it really possible?"
"It must be true if Yiyi said so." Grandma Zhou knew why he was so excited and patted his hand to comfort him.
It turns out that the radiation in Grandma Zhou's body has reached the threshold. Before the apocalypse, she can still go to the hospital for radiation elimination treatment. At her level, using medicine has no effect. However, this apocalypse directly destroyed various instruments, and she He could only endure all kinds of pain caused by radiation, so Grandpa Zhou was so excited when he heard what Song Yi said.
"Grandma's radiation contamination has reached the threshold, so hurry up." After hearing grandma's explanation, Song Yi stood up immediately and took out a bathtub: "Your situation is more serious, it is best to take it internally and externally. Used together, this can remove the radiation faster, but it will be very painful."
"It doesn't matter, I can bear it." Grandma Zhou said, she would rather feel a little pain than deform and become a monster.
"Then let's get started." Song Yi filled the bathtub with water, poured a bottle of medicine into it, and then asked her grandma to take off her clothes and get in.
