I have been sleeping for 500 years and I opened a supermarket in the end times

……

Yao Xue slowly opened her eyes and suddenly realized that Ji Yan's voice had stopped for a long time.

Ji Yan found a cup from somewhere and drank water slowly while leaning sideways and looking down at the swarm of insects outside.

I caught a glimpse of Yao Xue opening her eyes.

She turned around and asked, "What kind of supernatural power is this?"

His tone was extremely firm, as if there was no possibility of failure for Yao Xue.

Yao Xue: "...spatial ability."

"Wow." Ji Yan raised her eyebrows and said lazily, "Congratulations."

“How big is the space?”

"3*3*3, 27 cubic meters."

"Hahahaha." Ji Yan exaggeratedly let out an unpleasant and strange laugh, just like the villain in a movie or TV show.

"God is really helping me." She was a little proud.

Yao Xue was almost used to her mood swings or strange behavior: "Why do you say that?"

"Because I want to..." Ji Yan deliberately dragged out the last syllable, "Be a wholesaler!"

"And you—" she pointed at Yao Xue, "are the retailer I want to develop!"

Yao Xue: “???”

It seems like I understand something, but it also seems like I understand nothing.

"juvenile--"

She patted Yao Xue's shoulder affectionately: "Are you interested in doing business?"

Yao Xue was a little surprised: "Why me?"

"I thought you would choose Jin Yi to cooperate."

"Ah."

Ji Yan sneered and said disdainfully, "That guy has more holes in his heart than lotus roots. I have to think over every word I say several times in my mind and think over it over and over again."

"It's too tiring to deal with people like this. I won't cause trouble for myself!"

"You are the best." She smiled and said, "You are more honest."

“He should be a reliable person.”

She smiled.

Yao Xue felt an inexplicable sense of oppression from her smile: "I will definitely not let you down."

Ji Yan tilted her head slightly.

"I will prove my determination with actions." Yao Xue vowed.

"very good."

Ji Yan turned and looked at the swarm of insects outside.

"We've been here for a long time. It's time to go out and get some fresh air."

She said it very naturally.

"Did you... find the salt?" Yao Xue asked uncertainly.

"Yeah, I just don't know if it's enough."

Before Yao Xue woke up, Ji Yan bought pork, rice, purified water and seasoning gift packs in the system mall.

【Wealth: 1235】

【5kg pure water (purchase price 3\sale price 5)

Seasoning gift pack [1kg each of salt, oil, sauce, vinegar and sugar] (purchase price 20\sale price 40)

5kg rice (purchase price 1\sale price 5)

1kg pork (purchase price 10\sale price 18)]

她买了5kg大米、3kg猪肉、300kg纯净水、51份调料礼包（盐油酱醋糖各51kg）。

1x1+3x10+60x3+51x20=1231

There are 4 gold left.

If it is not enough, the worst that can happen is that she will go out to hunt in the wild for a while. Anyway, the nuclear battery in her nuclear bicycle has just been installed not long ago, and there are three nuclear batteries in the warehouse. Now that she has superpowers again, she doesn't need a laser sword in normal battles. If nothing unexpected happens, the remaining nuclear batteries will be enough for her to collect a lot of crystal cores.

Moreover, she can now make purchases in the system mall twice a day, which reduces the waiting time and makes her life much easier than before.

She could just ride her nuclear-powered bicycle and walk away.

If I wasn't a little reluctant to leave Yao Xue and the others.

She wouldn't bother with such trouble.

After this matter is resolved and Yao Xue has money to earn from selling things, she will go to the north to see the Great Wall.

Climbing the Great Wall while being besieged by all kinds of mutated animals, plants and zombies is a rare experience!

"By the way, what is the concentration of salt water that will be effective?"

Yao Xue was still in shock, but she came to her senses and replied, "20% and above is fine."

To prepare 20% concentration brine, there are 51 kg of salt, so 204 kg of water is needed.

To be on the safe side, prepare a higher concentration and remove any water residue.

That is 51kg salt, 200kg water (40 barrels of water).

Is about 500 kilograms of salt water enough to kill these insects?

Ji Yan sighed softly, and still needed to use the bomb from the gift pack.

Let’s wait and see tomorrow how powerful the bomb is.

If the bomb is effective, use the bomb as the main method and salt water as the auxiliary method; vice versa.

Suddenly I have the urge to give up...

No, no, you can't always be enthusiastic about things for only three minutes.

……

In the early morning, everyone woke up except Mu Qingyang who was still unconscious.

Ji Yan took out both water and salt.

Everyone (except Yao Xue and Jin Yi) was shocked when they saw this.

Fang Fei was so excited that she burst into tears.

Jin Yi saw Ji Yan taking out the salt when she was cooking meat yesterday, so he was not very surprised.

He seemed not to have slept well, with some faint dark circles under his eyelids.

"You guys prepare the salt water." Ji Yan waved her hand and got on her nuclear-powered bicycle. "I'm going to drop the bomb. Bye!"

After saying that, he drove out and flew into the air.

Considering that if the bomb is very powerful, the aftermath will also be very powerful.

Therefore, Ji Yan came to the outermost part of Chenfeng Base and flew over the city wall.

After a few seconds of silently mourning for the ancient city wall that was about to be destroyed.

Ji Yan carefully took out a bomb from the system warehouse.

The shape of the bomb is a bit like an apple, beige in color, and slightly larger than a human palm. There is a red switch in the depression, and a warning is posted under the switch: After pressing this switch, the bomb will explode in 10 seconds, please pay attention to safety.

"It's just a grenade!"

Ji Yan glanced at the insects still squeezing and moving below.

A ball of blue energy gathered in the palm of her free hand.

An ice chain emitting white mist stretched out from the energy ball, circled the bomb several times, and dragged the bomb into the insect pile.

Halfway through, the chain branched out into a small chain, which pressed the switch of the bomb.

Just when arriving at the swarm of insects.

"Boom!" There was a loud noise.

The bomb exploded, and within a radius of about 3 meters with it as the center, insect blocks and concrete blocks were blown up to two or three meters high, raising a cloud of thick smoke and dust mixed with the smell of gunpowder and insect blood.

There is also a faint aroma of burnt meat.

When Ji Yan thought about insect meat, she lost her appetite and even almost vomited out yesterday's dinner.

The smoke cleared, and red-orange flames were still burning on the messy ground.

"The effect is good. The remaining 99 bombs are enough to deal with other bugs."

Following the same method, she completely eliminated the bugs in other parts of the base except the building.

Why not address the bugs outside the building?

She was a little worried that the bomb would tilt or even knock the building down.

It's better to deal with those bugs with salt water.

(??`??)
