Only by quickly resolving the immediate troubles can you get back on the road.

With the booming rumbling sound, countless zombies were blown apart, and the originally broken bodies were even more dilapidated.

You can't eat for a few days at a glance.

Of course, this was addressed to the trio in the car.

Zhao Yuan and the others tried their best to hold back the churning stomach, and looked at the scene in front of them with trembling limbs.

At this moment, they are more deeply aware of the cruelty of this world.

"It's over, it's all over......"

"I don't know what happened to my parents, they-"

Tears welled up in the eyes of the three of them, in this impermanent world, it is not easy for them to live.

It is a luxury to be able to ask for other things.

Professor Zhang sighed, "Aren't they going to take us to the base, maybe our family has already gone, don't be too pessimistic." ”

The road back was not uneventful, nearly 30 kilometers from the People's Hospital to the Central China base, which would normally be only one or two hours.

However, it is incredibly far away for the present.

The street in front of the hospital alone stopped and walked for an hour, and when the sun went down, I had to find a place to stay.

"There's a hotel in front, and there aren't many zombies nearby."

After going around for a long time, Shen Xingluo chose a remote alley.

This area belongs to the old city construction area, the buildings are not high and not crowded, the young people have long moved out of this area, and most of the old people who can stay are old-fashioned.

Xu Qingzhou quickly led people to clean up the old man's version of the zombies nearby, and successfully entered the interior of the 6-storey hotel.

Each of the three of them distributed sandwiches and mineral water for lunch, and were forced to rest to regain their strength.

Shen Xingluo and Cheng Xi chose a room by the window to rest.

In the space, the two of them were silently speechless as they looked at the 2,500 crystal nuclei that sank in the basin.

Why not 5,000?

Of course, it is used to repay those defensive bracelets purchased from the system store, and the rest is pure income.

"Huge profits!"

Cheng Xi sighed, "Why didn't you give the price a high point in the first place?" ”

Shen Xingluo smiled, "This is already half of the money, if it is too expensive, ordinary people can't afford it." ”

"That's the truth...... Well, the right is considered charity. ”

Although the two are not from this world, and their sense of belonging is less, watching people suffer is something that only neuropathy can do.

She stretched out her hand and poked the crystal nucleus in the water, and the other party floated upwards and then sank again.

"So how exactly is this thing used? The scientists at the Central China base are also too inefficient, and they haven't studied it for a month. ”

For such a long time, I only came to the conclusion that there is manic energy in the crystal nucleus, use it with caution.

"System, you know what?"

[Little sister, there is indeed unstable manic energy in the crystal nucleus, and you can't take it directly! ] 】

"So, can you solve the problem?"

[Yes, you need to melt the crystal nucleus and separate the manic energy part, and you can take the rest!] 】

"Take? It turns out that this thing is taken orally...... Wait, that's not the point. ”

Cheng Xi said, "The hardness of the crystal nucleus is comparable to that of a diamond, how to melt?" ”

[There are machines in the system mall that can be purchased~]

Okay, got it.

Trick me into spending money again.

Cheng Xi looked at the sky speechlessly.

Shen Xingluo's attention was on another matter, "It is impossible for the people of the base to put their hopes on your so-called machine, for this world, how to solve the problem of crystal nucleus melting?" ”

He had seen the hardness of the diamond in a book.

If the crystal nucleus were as hard as a diamond, there is a good chance that a machine capable of melting it would not exist.

In other words, the crystal nucleus cannot be used by the supernatural.

No, it won't.

Shen Xingluo quickly denied this conclusion, time and all things are mutually reinforcing, and there is no problem that cannot be solved.

His obsidian eyes flickered, and he thought of a possibility.

"The virus that causes zombies comes from extraterrestrial meteorites, so the solution should have something to do with it, right?"

[Yes, the host is so smart!]

！ 】

[Extraterrestrial meteorites belong to metals, and the matter contained in them and the manic energy in the crystal nucleus are mutually restrictive and can be completely separated. 】

"No wonder ......"

The scientists at the base made no progress in their research, and it turned out that they had chosen the wrong direction.

"Remind Xu Qingzhou tomorrow."

As for whether it can be studied later, it depends on the experts.

Cheng Xi clicked on the plane mall page, and turned back many pages before finding a machine that could purify the crystal nucleus.

However......

", grab money!"

The unit price below is prominently marked with the words 10,000,000 Star Coins.

Ten million, good fellows!

Cheng Xi glanced at the crystal nuclei in the water basin, 2,500, which is 2.5 million according to the exchange ratio of 1,000 interstellar coins for one crystal nucleus.

There is still a gap of 7.5 million.

It's not enough to buy a machine, it's also purified and even ah!

Cheng Xi left tears of poverty, "Profiteer, profiteer." ”

Compared to the cold spirit, she is just a drop in the bucket.

Shen Xingluo saw that she was lost, and his heart moved, "Do you want to make extra money?" ”

What?

Ten minutes later, Cheng Xi finally knew what it meant to make extra money.

They came out of the space, climbed down the hotel's low windows, and ran out onto a nearby street.

And the zombies that were originally dancing with teeth and claws seemed to be a lot quieter during the day, leaving only a bunch of unknown sounds of Kacha Kacha.

Shen Xingluo shoved the machete into her hand.

"Be as quiet as possible."

"Got it."

Sullen to make a fortune or something, she likes it the most.

So the two avoided the crowd that fell asleep and started the mini-boss experience, looking for the crystal nucleus when they cut it, and going back to the space to rest when they were tired.

After the night, several streets outside the hotel were cleared.

And the two who spent one night for several days also gained a lot.

“7538，7539...... That's enough! ”

After returning to the hotel, the two quickly exchanged 10,000 crystal nuclei for a purification machine and placed it in the space.

"There are 40 crystal nuclei left."

"Creek."

"What's wrong?"

Cheng Xi, who looked down and counted, raised his head and looked out the window with Shen Xingluo's solemn gaze, and saw that the sky was dark and gloomy, which made people desperate.

"The sun is skipping?"

"More than that."

Shen Xingluo detailed his intuition, "This weather is unusual, system? ”

【Cloud Detection......】

[After testing, the clouds contain a large number of virus elements, exactly the same as the virus that came with the meteorite. 】

[Host, when the meteorite pile broke through the atmosphere, it left a small number of viruses in the clouds, and when this rain falls, it will destroy the soil structure and affect the water source. 】

"In other words, after the rain, the soil and water will carry the virus, so it can't be used?"

[In principle, it is. 】

"So, what effect does the rain itself have on the rain-drenched people?"

[All contacts will be eroded by the virus and may become zombies. 】
