"Let's go, let's go home." Grandma Song pulled Song Yi into the house.

"Yiyi, where's your luggage?" Grandpa Zhou, who was left behind, originally planned to help with the luggage, but found that Song Yi was empty-handed, and there was nothing else except a pair of strange wings on his back, so he asked.

"It's all in there." Song Yi picked up the satchel-style space bag on his waist, "This is a space bag, there is 6 cubic meters of space in it, and everything is packed in it." ”

Of course, this space is not her largest space, although the people have become smaller, but the plants have become larger, Song Yi has stored a lot of mutated plants and seeds, and naturally it has filled a lot of space.

"Space bag? Is it storage? Hearing her words, Grandma Zhou asked curiously.

"Yes, we've researched a magic array that attaches abilities to items, and this is the storage space that has been repaired to expand the magic array." Song Yi nodded.

"This is similar to your grandfather's abilities." Grandpa Song said.

"Hey, what's Grandpa's ability?" Song Yi was a little curious, when she asked before, her grandfather didn't have any abilities.

"In your dad's words, it's enchantment." Grandma Song said.

"That's a lot like that." Song Yi knew that his father's awakening was a detection ability, which was similar to the identification technique but had some differences.

While talking, they entered the house and sat on the sofa in the living room, "How is the situation at home for more than half a year?" Song Yi asked after sitting down.

"The family is fine, everyone is alive." Grandpa Song said that for him, it is the best thing to encounter the end of the world, and everyone in the family is alive.

Song Yi knew from the words of several old people that now the two families live next to each other, her parents and uncles have jobs, and even her younger siblings are busy, so there are only four old people in the family.

"They should be back for dinner in a while." Grandma Song looked at the time and said, after talking about the situation at home, she asked about Song Yi's situation: "What about you, how have you come over in the past six months." ”

"I'm ......" Song Yi told him what happened to him for more than half a year, and gathered all the teachers and students of the school to set up a temporary base after the end of the world, how to find a secret warehouse to get controllable nuclear fusion fuel to survive the cold winter, including the matter of them convicting He Xiao together.

"I brought a lot of good things back," Song Yi opened his space bag and took out all the same things:

"This is a flying wing, you can fly if you wear it on your back, I brought a few for everyone, this is the guinea fowl, and its eggs, and these space bags are also one per person."

"These are the seeds of mutated sweet potatoes, sunflowers, oil fruits, healthy fruits, stealth grass, pure spirit grass, purification grass, rice fruit, repair flowers, wine grass, flying flowers, bright eye grass, stand-in grass, bloody grass, and this, a flying skateboard transformed with a magic array, this is the clothes I specially made for Xie Xueyi, with a constant temperature magic array added to it, with this, you don't have to worry about the temperature, everyone in the family has two sets."

Then she gave a detailed introduction to the use of those seeds, Grandpa Song's eyes were about to glow, he was a professor at the Institute of Botany before he retired, Song Yi would learn this, and he still took it.

"These are your modified mutant plants?" Grandpa Song knew the ferocity of today's mutant plants, and even those that were identified as useful were basically aggressive.

"Yes, it's all improved and domesticated." Song Yi nodded.

Substitute grass, bloody grass Song Yi also specially asked Mr. Liu to domesticate and improve them, the substitute grassland is originally a parasitic plant, will parasitize on the prey, and slowly become the appearance of the prey, the bloody grass will take the initiative to attack and inject toxins.

After domestication, the stand-in grass retains its original characteristics, but no longer has the ability to parasitize, and the bloody grass is still highly poisonous, but it will no longer actively attack.

"This ability is good, why don't I have such an ability." Grandpa Song said regretfully after listening to the process of domestication.

"Grandpa, do you want to try this, this is a marrow washing potion, which can wash the essence and remove the radiation pollution from the body." Song Yi took out a few bottles of potion and said.

Although the pain was abnormal after using the marrow washing potion, Song Yi still took it out, grandparents and grandparents are old, and the radiation pollution in their bodies is much more serious than that of young people.

Before the end of the world, although everyone tried 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 could not be avoided, so everyone had radiation contamination on their bodies, and they needed to undergo radiation elimination treatment on a regular basis.

However, the effect is limited, and as we age, the radiation contamination will precipitate more and become more difficult to remove, even if human beings are desperately researching drugs to remove radiation contamination.

Three hundred years later, the average life expectancy of human beings has only reached 81 years old, and it is because of radiation pollution that many scientists have shown that if there is no radiation pollution damage, the maximum life expectancy of human beings can be increased to 150, and the average life expectancy can reach at least 130.

Although the ability seems to strengthen the bodies of some grandparents, the effect does not look great, and the grandfather, who is only 76, looks older than the old man in his 70s 300 years ago, and she knows that these are the effects of pollution.

In fact, now human beings have minimized the harm of radiation to the human body, and it may be that human beings have also had some immunity for so long, so it is only the life span that is affected, not various pathologies, it is said that radiation pollution has just begun to be serious in those years, and people who are distorted by radiation appear every day in the world.

Even so, radiation contamination should not be underestimated, so she specially made a lot of marrow washing potions before coming back, just to let her family use them as soon as possible.

"Can you remove the radiation contamination?" Grandpa Zhou immediately raised his head, "Is it really possible?" ”

"Yiyi said so, then it must be." Grandma Zhou knew why he was so excited, and patted his hand to comfort him.

It turned out that the radiation in Grandma Zhou's body had reached the threshold value, and she could go to the hospital for radiation elimination treatment before the end of the world, and to her extent, the medicine had no effect, but this end of the world directly destroyed all kinds of instruments, and she could only endure all kinds of pain caused by radiation, so she was so excited when she heard Song Yi say this.

"Grandma's radiation contamination has reached the threshold value, so hurry up." After listening to her grandmother's explanation, Song Yi immediately stood up, and at the same time took out a bath bucket: "Your condition is more serious, it is best to use it internally and externally, which can remove the radiation faster, but it will be very painful." ”

"It's okay, I can bear it." Grandma Zhou said that she would rather hurt a little than become a monster.

"Then let's get started." Song Yi filled the bathtub with water, poured a bottle of potion into it, and then asked her grandmother to take off her clothes and go in.
