At 0:00 on January 6, she received a new world mission in Star House.

【The fifth end-of-day world:

Difficulty: medium and low.

World type: natural disaster, type: acid rain.

World time: 18 hours before acid rain.

World Identity: Sophomore.

World mission: 1, survive for three months. (You can get 60 star coins after completing), 2, and random refresh task. (Optional, the number of star coins you can get to complete depends on the selected task).

World Mission Failed: Death.]

Youxi:...

This second task seems a bit willful.

[Random refresh is not a task, but several small tasks, with different difficulties. The host can choose to receive or not. Once the task is received, it must be completed. If you choose not to receive, a new task will be refreshed. The maximum number of rejected tasks is 3 times, if it exceeds it, it will be judged as a task failure.]

Youxi:...

[Host, most random refresh tasks are simple tasks. It is recommended that the host actively accept tasks. Not every time the end of the world will have such a world task.]

"Okay, I get it."

She still believes in the Star House system now. Afterwards, she looked at the word "acid rain" and hissed softly.

If it can be so serious that it becomes the acid rain in the end of the world, either the rain water is very acidic or the frequency of acid rain is very high. Judging from the difficulty of the end of the world, the difficulty is not higher than that of meteorites and zombies.

So she temporarily tends to the latter in the general situation of acid rain, because if the acidity of the rain is too high, even the building will be corroded, and then she will not have the task to be medium or low in less than three months.

【…】

She noticed Xingwu's desire to speak again and smiled: "How is it, am I getting smarter and smarter?"

【…】

This time the Star House is in a state that is closer to speechlessness.

You Xi recalled the inventory. Fortunately, she stocked up a lot of air-tight chemical protective clothing, and also stocked up some exhalers and oxygen cylinders. However, the number of oxygen cylinders was not large, so she was afraid that when there was a sour rain, the acid gas would cause damage to the trachea and lungs.

While opening Xingwu Mall, You Xi was thinking about going out tomorrow to get some oxygen cylinders, but found that the mall was new.

[Hydrating breathing mask: 24 hours a day. Disposable items have adsorption function. After use, they automatically form a protective film on the face, breathe freely, and isolate all toxic gases and substances. Price: 8 star coins.]

Youxi:...

Isn’t this the oxygen breathing cover on the face? It’s also the oxygen hood that lasts up to twenty-four hours at a time! Although it costs 8 stars, it is a good tool to save your life in the end of the acid rain!

"Tongbao, you can release water so obviously..." She was delighted and even changed her name.

The new star tool is beneficial to Youxi, and it is obvious that the Star House system wants her to live.

But why? Is it related to another system tower?

While she was thinking, she bought two.

The mask is placed in a translucent bag, and you can clearly see the mask. It is not the mask with three holes she imagined, but a half-face mask, and it is silver-gray, which looks very much like a protective mask.

However, with this on her face, at least it won’t make others mistakenly think that she is a “heartless person who doesn’t forget to apply a facial mask even in the end of the world”…

During the day on January 6, she originally planned to call the hardware store first, then drive out, and lay thin copper sheets on the inside and outside of the umbrellas in her hand.

Copper is anti-acid. In fact, all acids have h ions in them. In the metal activity order list, the metals ranked behind h cannot react with the acid - that is, they can be anti-acid.

In addition to copper, there are also gold, silver, and titanium...

But she couldn't use gold and silver to lay the umbrella, so copper is the best choice.

However, in the early morning, after she got up from the tent, she was shocked by the city outside the window before she had time to wash up.

Overnight, everything grew, and from her height, the city fell into a green ocean.

The rain has stopped, the sky is blue, as clean and clear as the sky in a fairy tale.

The plants that were once completely burned to ashes were revitalized again, with big trees growing and lush branches and leaves. A residential building, vines climbed up from the walls, wrapping around the balcony on the second and third floors, laying the green and flowers on the balcony.

Many people have three floors below the glass of houses covered with various green vines, and the people inside cannot even open the windows.

Unlike last time, most of the plants this time were quiet. Before the sun came, they silently completed their growth and unknowingly occupied most of the space between the buildings.
Chapter completed!
