Doomsday Fast Travel: Kill That Black Butterfly

After a century of vicissitudes, the glass gate of the main building of the Observatory still stands tall at the top of the stairs.

The sturdy door shaft did not deform under the intentional or unintentional collisions of many animals.

Yu Di knocked on the lock, pushed the door open and walked in.

In a relatively closed environment, the fishy smell is not so strong, and naturally there is no lingering rancid smell in the tunnel.The faint musty smell emanating from the ventilation ducts simply made Yudi feel refreshed.

After stopping for a while in front of the sign, Yu Di found the floor she wanted to go to - the reference room.

She knows too little about the world, which makes her make all kinds of plans, like a blind man touching an elephant, with a hammer here and a mallet there.Now that there is such an opportunity, it is natural not to let it go.

Most of the doors here are electronic locks, and the door locks are open when there is no electricity.Most of the equipment in the reference room are dusty servers, only some paper materials are placed in the exhibition room.

The plastic-covered magazines are okay, but the newspapers and documents are so fragile that they shatter when touched.Those who stayed here until the end cut a lot of news and put it in their notebooks.But for some reason, the book was not taken away.

Yu Di carefully flipped through, and with the notes made by the owner of the book, the things that happened in this world a hundred years ago slowly pieced together before her eyes.

300 years ago, this planet was going through the Fourth Cold War.In order to compete for energy, countries in different camps are desperately developing new technologies, trying to find new available energy on the increasingly depleted earth.

Air supremacy is almost divided in half, but the universe they live in is a relatively empty area, and they can only focus on the planet itself.

Under the development of catching up with each other, one of them achieved results first, and seeing the capital flow to the other party, the laggard decisively lit the fuse, turning the cold war into a "hot war".

You don't need to think about what happened later, the population was exhausted, and the adults ran to the space station to avoid the devastation on the surface.

Losing the support of the group, coupled with various radiation diseases, mutations, etc., the remaining human beings are simply not enough to maintain the operation of a huge gathering place, and there are no more relevant reports.

The owner of the note wrote a paragraph, the general content is to hope that human beings can return to the surface.It's just that this is no longer the earth they are familiar with, and Yu Di doesn't hold much hope for it when she thinks about what happened along the way.

It is worth mentioning that among these documents, she found the detailed meeting minutes of the Skydome Project, the immigration space station project.

According to the records, there is still a transmission tower on the surface that is still working.I always feel uneasy with my feet on the ground. This launch tower is to assist the maintenance of the space station.

According to the plan, every ten years, the space station will send a team of environmental scientists to investigate the condition of the earth.Yu Di calculated the time, and it was already the eighth year.If she can arrive at the launch tower before April next year, she can take the initiative to contact the expedition team.

Compared with using a laser to shake the space station, the success rate of directly looking for it is obviously higher.

With this news, Yu Di was very excited.Human beings are the core of the civilization here. If you come into contact with them, you should be able to know what kind of end times you are facing this time.

Still, there are several survival issues that now need to be addressed.

Yu Di climbed to the highest point, looked in the direction she came from, and finally managed to see half of the outline of the sky-shading tree covering her all the way.

Numerous aerial roots float in the air, and some grow in the ground, forming new trunks.The crown of the tree is like a mushroom cloud. Looking at the distance, the main trunk should be in the southern area.

On the roof there is a telescope that has fallen to the ground. The barrel has been corroded, but the mirror is not broken.Yu Di made do with it and looked at the sky-shading tree, only to figure out what it was that kept dripping mucus at her——

spider.

Giant spider.

The thick spider silk is entangled between the aerial roots, like they are on an assembly line, they are constantly hanging in the air and spinning downwards, wrapping the sticky things with saliva, and sending them to the inside of the tree crown that cannot be seen clearly.

And after a while, these "cocoons" will be spit out from the inside of the tree crown, and it is them that hit Yu Di.

Yu Di touched the wound on the top of her head - it seemed that not only food and water needed to be dealt with, but she also needed the entire means of transportation at hand.

As a former office area, there are still many places to explore in the main building of the Observatory.

Yu Di found a small can of unopened sugar cubes in the drawer. The coffee powder next to it had turned into ashes, and the can of sugar didn't seem to be affected.

She regarded the antique candy as a symbol of good luck, unceremoniously opened the jar, squeezed a piece into her mouth, and continued to look for odds and ends.

The inside of the vending machine is also full of dust, and all the packaging bags have been deflated, and traces of mold can be clearly seen.

But what made Yu Di quite happy was that after breaking open the machine, there was a whole surface of mineral water, well sealed, lying in front of her eyes.

After searching the two floors, the harvest was quite fruitful.It's just that my head is starting to feel dizzy, so I have to come here first today.

She built a fire in the corner of the hall on the top floor, opened a package of candied fruit and roasted it on the fire.

A bit bitter, but should be edible.

If Birdman comes here, he should be very excited, right?Across the wilderness, it was a different scene.

On the second day, Yu Di started to prepare for the next journey.

She found some working devices that, if they worked, might be able to communicate directly with the space station, but they all needed electricity to power them.

With such a large venue, Yu Di guessed that there should be a backup generator somewhere.It's just that after so many years, can they still be used?
Although she doesn't have much hope, if there are enough components, she can find a way to modify it.

She still remembered the structure and principle of biological motors.After studying on Jialu Planet, she reckoned that if she had the conditions, she should be able to get a similar one.

Just do it.It is a long way from here to the launch tower, and there is not much time left for Yu Di.She couldn't get fuel, and the antique cars scattered around couldn't be driven. If the power generation didn't work, she had to get on the road as soon as possible.

Yu Di stepped on the disassembled cart made of computer chairs and wooden tables, slid back and forth in the wide aisle, and soon collected all the required components.

There are quite a few tool boxes in the maintenance room here, and many of them can make do with it.Cultivable microbes are made from local materials, which means sacrificing the jar of sugar cubes she only ate.

There is no way to give up, she can be hungry, but these little ancestors can't be hungry.

While waiting for them to grow, Yu Di successively produced an air gun and a frame, and returned to the city fully armed. It took two full days to overshadow the giant goose.

She hurriedly dragged the food away from the range of the sky-shading tree, almost becoming a big meal for those spiders.

The quality of the strains here is also very strong, even if Yudi is equipped with a not very high-end culture medium, they will thrive.The moment the indicator light inside the motor finally turned on, Yu Di was about to cry——

With electricity, the original source of energy, she can use these devices to directly try to contact the space station!
