The end of the world begins with escape

Song Youai looked at the two of them helplessly, "Aunt Song has been making ice cubes all morning, and now the energy is almost exhausted."

"I'll give you five liters of water for cooking and washing your face. How about you come back tomorrow to get water?"

Li Dawei and Li Xiang murmured and discussed for a while, then reluctantly nodded, "That's it, Aunt Song, I'll give you this cabbage first."

"Among so many people, we trust Aunt Song's character the most. We will come back to get water tomorrow."

Xie Ning looked at the brother and sister with a small face.

What does it mean?

Can’t you trust Captain Xie?

I originally wanted to tell them that they could just come and get water at night.

Now Captain Xie is not happy to talk about it!

Tomorrow is tomorrow, hum.

Song Youai took the bag of cabbage with a smile, "Okay, here's your water container."

Ge Yan stepped forward and took out a container, Song Youai poured five liters of water into it, and then smiled and said, "Come later tomorrow, Aunt Song will definitely recover."

Several people nodded one after another, said goodbye to Song Youai and left.

Xie Ning looked at her mother's happy expression and turned her head silently.

"Li Xiang actually knows how to cook, which is pretty good."

Xie Ning:......

Are the mother's requirements for the Li Dawei siblings too low?

"Auntie, are you back too?" Song Kexin jumped over and chirped, "When we came back, we met my sister on the road, and we went to the survivor center with her to deposit and withdraw contribution points. Now each of us has forty contribution points in our account. Oh."

"Hurry up and eat, it's almost one o'clock!" Song Yaoguo, wearing an apron and holding a shovel, ran to the corridor pavilion and shouted.

A few minutes later, everyone went to the second floor of the independent dining hall and sat in a circle holding bowls.

"The experiment has made some progress." Yu Tianfeng was the first to speak. "I extracted some substances from the blades of the inhibitory grass and added some other elements into it. The inhibitory effect can be doubled than before."

Xie Ning's eyes lit up, "Does that mean it can be effective on those with second-level powers and below?"

"Yes." Yu Tianfeng nodded.

"Then make some inhibitors first and prepare them for grandpa, grandma, aunt Yueyue Nanxing and the others."

"Yes, we are working on it. It will probably take about a week."

"In addition, I still need some small medical equipment here. If possible, you can help me pay attention to it during the mission. Here are the drawings."

Xie Ning flipped through the drawings and took out a few of them, "Right?"

"Yes, yes." Yu Tianfeng was a little funny, raising his hand to put away several medical instruments, "Ning Ning, you really can put away everything!"

Anyway, I keep everything I like and don’t like in the space. Maybe this is my hobby of collecting?

Xie Ning's face was expressionless, "We'll help you look for the other items when we go out."

"If you don't have enough space in your small room, I can help you build a tin hut next to it."

"Well, if you can let me put the machine in, the room won't be so crowded."

“It’s just going to be hot!”

"It's okay. I often make some ice cubes for him. If it doesn't work, just connect an air conditioner and use it. Don't burn out the medical equipment." Song Youai said.

Xie Ning nodded, "Let's do it after dinner."

"Where's the earth-type superpower?" she suddenly remembered.

Song Shijun held back his laughter, "The earth-type psychic collapsed from exhaustion after working all morning. I'll move him to the living room and let him sleep on the sofa."

Zhu Yong put down his chopsticks, "Would it be better to build a mud house to dissipate heat? It just can't withstand heavy rain."

Xie Ning blinked, "That's okay, then build an earth house. Pour a metal floor and cover it with earth, and add a metal roof so you won't worry about rain leaks. What do you think?"

"Okay!" Everyone nodded in unison, with great interest, and planned to wait for the next one to help build a house.

"Hey, aren't you all curious about how much we made all morning?" Song Kexin couldn't hold it in any longer, with a "Ask me, ask me, ask me" look on her face.

Ji Tae-hyun was particularly supportive and hurriedly asked, "How much do you earn?"

Song Kexin chuckled, took out a small cloth bag, and pressed it on the table, "Sister gave us four sets of metal knives, each set has five knives of different specifications, lengths, and sizes."

"From large to small, from daggers to metal knives, there are a total of twenty knives. A total of five second-order crystal nuclei and two hundred first-order crystal nuclei have been harvested!"

"There are also one hundred contribution points."

Song Youai opened his mouth, "That's more money than I make selling ice."

Xie Ning couldn't help but wonder, "How did you sell it?"

"Haha." Song Kexin said proudly, "At first we didn't understand the market and sold at a loss. We sold daggers and daggers for one pentacrystal core, and sold four. It felt like there was an endless stream of people coming."

"We were smart enough to raise the price of daggers and daggers to ten cores."

"The medium knife is priced at 20 cores, the medium long knife is 25, and the long knife is 40. I didn't expect that there are still a lot of people grabbing it." Song Ke raised his eyebrows in joy.

Song Shijun nodded and said with a smile, "Well, the customers who finished their purchases also brought many repeat customers, saying that the quality of the knives made by my sister has never been better!"

"Nowadays, first-order crystal cores or contribution points are used as currency in the market. One first-order crystal core is equal to one contribution point."

"One second-order crystal nucleus is equivalent to twenty first-order crystal nuclei."

Xie Ning smiled and touched Song Kexin's head, "I didn't expect you guys to be quite good at doing business."

Song Youai curled his lips, "I don't know the market conditions either. Anyway, sit down and I will tell you, five crystal nuclei for one ice."

"Business is pretty good, but it's also quite tiring." Song Youai couldn't help complaining, "Later I felt that I had made a loss, but seeing them all surrounding me, calling me "girl, aunt," I was too embarrassed to mention it. price."

"Think about it. Today is just a trial opening. Let's talk about it later. Anyway, we don't sell ice every day."

"So Auntie, how big is the ice you sell for 5 crystal nuclei?"

"Is it almost this high?" Song Youai made a gesture.

Everyone's eyes suddenly widened.

"So, that big?"

Xie Ning was funny and angry, "The person who bought your ice must be very happy. This ice melts into water and you can drink it. Such a big ice should melt five liters of water."

"Five liters of water and five crystal nuclei? Auntie, you're in trouble!" Song Kexin shouted.

Song Shijun laughed loudly, "Yes, aunt, how did you settle the score?"

"Did you know? Five hundred milliliters of water in the base costs six contribution points! You! Hahaha, five liters of water only costs five crystal cores, which is equivalent to five contribution points! Hahahahaha, laugh to death."

Song Youai's face became hot when she was laughed at by her nephew and niece, and she coughed slightly, "I, I can't do half-sell and half-give away. Forget it, then, it's not that I don't understand the market. I will raise the price in the future."

She took a bite of green vegetables and muttered to herself, "No wonder the crowd was so crowded later that I almost couldn't breathe."

"But it's okay. I've also been practicing my water powers. I'm a girl, aren't I?"
