Grandpa Song and Grandpa Zhou walked away, leaving only Song Yi and Grandma Song here to take care of them, and after Grandma Zhou drank the medicine, she sat down in the bathtub, "Grandma, you bite this, it really hurts, I almost rolled at the time." Song Yi took out a towel and put it to her grandmother's mouth and said.

"Okay." Grandma answered, biting the towel, and after a while, fine beads of sweat began to appear on her forehead, and the hand that grabbed the edge of the bathtub was bruised.

Song Yi wiped her grandmother's sweat beside her, but there was no way, washing the essence and marrow was so painful, there was no way to alleviate it, after all, it was to exclude the impurity pollution that penetrated deep into the bone marrow cells, how could it be comfortable.

Fortunately, Grandma Zhou was a strong-willed person and survived hard, and at this time, the water that was originally filled with a faint medicinal fragrance had begun to emit a pungent stench, and Song Yi hurriedly threw a few Pure Spirit Grass into the bucket after helping people out, and the Pure Spirit Grass grew rapidly.

After the improvement of the Pure Spirit Grass, it grows faster in the more polluted places, and especially likes radiation pollution.

"Huh, Yueli, you look like you're forty or fifty years younger." Grandma Song put a towel on Grandma Zhou, and then said in surprise.

"That's an exaggeration." Grandma Zhou opened her mouth a little weakly.

"Really, Grandma, you look a lot younger, you see for yourself." Song Yi turned on the light screen and adjusted it to take photos.

"Is this me?" Grandma Zhou was a little incredulous, just drank a bottle of medicine, she actually looked forty or fifty years younger, she looked like she was more than a hundred before, but now she looks like she is only fifty or sixty.

"It seems that this potion is really useful, no wonder Yiyi looks much younger when he comes back, it seems that it should be the credit of this potion, and it will be me next." Grandma Song said that which woman doesn't love beauty, Grandma Song is no exception.

"Grandma, wait." Song Yi saw that she wanted to do it by herself, so she hurriedly stopped, "You wait for me to dress my grandmother." She first rinsed Grandma Zhou's sewage and then put on the clothes she brought back.

"You go get it for your grandmother, I'll wear it myself." Grandma Zhou had regained some strength, and after washing it, she waved her hand and asked her to help her grandmother get it.

"The water has become clear?" Grandma Song walked to the edge of the bath tub and looked at the pure spirit grass that had grown more than ten centimeters high, and then looked at the inside of the bucket, the water in it was originally blue and black with a foul smell, but now it has become crystal clear, and the white bath bucket can directly see the bottom.

"This is a pure spirit grass, which can absorb pollution and convert it into its own nutrients, and my favorite is radiation pollution." Song Yi walked to the mutiny and said after taking a look.

"If only there were this before the end of the world." Grandma Song sighed.

"It's not bad to have it now." Song Yi said.

"That's right, this water can be used directly." Grandma Song nodded, and then asked.

"If you don't dislike it, you can use it directly, to this extent, it's basically close to pure water." Song Yi replied.

"Then use it, the end of the world, there is not so much attention." Grandma Song waved her hand, she could still pay attention to it before the end of the world, but now she can't, although the house has been built and the groundwater has been found, there is no running water, and the water at home is all put by Zhou Xia, that is, Song Yi's little uncle.

Grandma Song, like Grandma Zhou, chose to take it internally and externally, although the radiation in her body did not reach the critical point, it was also a lot, so it was naturally better to remove more radiation.

When Grandma Song took effect, she came out of the bathtub, rinsed it and put on her clothes, and she also looked forty or fifty years younger, and Grandpa Song and Grandpa Zhou were stunned when they came in and saw it.

"Why are you so young?" Grandpa Zhou was a little incredulous.

"It's all potions with clothes, you guys should try it quickly." Grandma Zhou said proudly, and then asked them to use it quickly.

The two old men naturally didn't want to be a generation apart from their wives, and immediately said that they would also use it, and Song Yi naturally used it for them, although the marrow washing potion hurt a little, but it was harmless to the body, otherwise she wouldn't dare to use it for a few old people.

Half an hour later, the two old men were also forty or fifty years younger, and Grandpa Song felt the strength of his body: "Yes, I feel more energetic than when I was sixty years old." ”

"It's smoother to use, too." Grandpa Zhou said after feeling it.

"Depending on your age, two more uses may not be able to completely remove the pollution, you can eat some guinea fowl often, and after a long time, it should be completely removed." Song Yi said.

"That's good." Grandpa Song said.

"We're back." At this moment, several not-so-neat voices sounded outside the door.

Song Ye returned home with his younger siblings, and after opening the door and entering the house, he saw several middle-aged people, "Who are you?" ”

"Night girl, you don't even recognize your grandparents?" Grandpa Song straightened his face and pretended to ask angrily.

"Grandparents? Grandparents? Why did you suddenly get younger? Song Ye's eyes widened in disbelief.

"This, it looks like my parents." Song Xu and Song Yin blinked, if it weren't for the wrong age, if they looked closely, they would still be a bit similar to their father.

"Grandpa, grandma, are you really you?" Zhou Ying's eyes widened and she was dumbfounded.

"Is it really grandparents?" Tang Xiu and Tang Yu were also unbelievable.

"It's true." Song Yi looked at his younger brothers and sisters and spoke.

"Wow, sister, when did you come back?" Song Ye looked at Song Yi at this time, and immediately jumped up excitedly, hugging Song Yi and jumping up.

"Cousin/cousin." Several other children also immediately surrounded Song Yi and Song Ye.

"Just came back." Song Yi replied with a smile.

"Cousin, it's so good that you're back, I miss you."

"Yes, sister, we miss you very much."

Several old people were very relieved to see this scene, Song Yi is the eldest of the grandchildren, 5 years older than the eldest Song Ye, these children have been brought by her since they were children (except for the nanny robot), so they are very close to her.

"Let's go get dinner ready." Grandma Song said to Grandma Zhou.

"Okay, they're about to leave work too." Grandma Zhou nodded, and the two walked to the kitchen together.

Grandpa Song had already picked up the Pure Spirit Grass that had just been used to clean the bath water and studied it, while Grandpa Zhou picked up the flying wings to study.

"Sister, grandparents, how did they get younger." After telling his thoughts, Song Ye asked this question.

"Well, they used the marrow cleansing potion I brought back to remove some of the radiation pollution from the body, and they became younger, do you want to use it?" Song Yi replied.
