Doomsday Fast Travel: Kill That Black Butterfly

Yu Di quickly noticed the difference between this body and human beings.The wide and thick soles of the feet are rough by nature, and they don't feel pain at all when they step on the hard and cold ground.The hard, elastic skin is covered with a light black down that has not fully grown from the skin.The same rough palm is very soft when pressed, it is the least cold place on the whole body.

Perhaps it is not human civilization that is to be saved this time, or because of the environment, human beings have evolved into something else.In any case, for a civilization that has come to the end of the world, the level of science and technology should not be too bad.

She thought silently, trying to ignore the decreasing body temperature.

Unless the planet in this world is square, the actual distance between people and distant landmarks is always farther than it seems.As for how far, it depends on how big the planet is.Yu Di walked on her little feet for about two hours. With the continuous exercise, her body temperature rose a little, and she no longer faltered.

As she got closer to her destination, she could see clearly that what her dead mother was looking at was not a mountain, but a group of black buildings in the shape of a regular triangular pyramid.Their bases are slightly gray due to the reflection of the ground, and their tops almost merge with the sky.The surfaces of these buildings are very rough, covered with countless dense depressions, like a cage specially built for light.

She searched for traces of the entrance along the periphery, and finally saw an inconspicuous seam in the depression between the two pyramids.She brushed away the icicles that covered it, revealing a solid round leather door.There was no place to grab a hand on the door, and she tried to push it a few times, but it didn't work.

The temperature continued to drop, the already dark sky became more and more gloomy, and the howling cold wind shuttled between the buildings, turning the ground gray.If she can't find a place to escape the cold, Yu Di will definitely freeze to death here.

But the damned door couldn't be opened or knocked. She struggled for a long time, but she didn't wait for anyone to take her away.She could only temporarily give up and think of other ways.

She picked up a few icicles and rubbed them on her fingertips, leaving a touch of dampness.The condensed water melts with body heat, leaving white spherical crystals that look similar to sand.Yu Di went to a place a little further away and tried to dig down. The ice slag melted by the temperature of his palm froze again under the extreme cold, forming a deep pit.

Originally, these ice slags were just stacked on top of each other, but after "processing", the formed structure was even stronger.Yu Di dug a snow hole for herself, one side was higher and the other was lower, and a hole for ventilation was left in it.Although the strong wind was still raging, it was much better inside the snow cave than outside.Yu Di's hands and feet were almost frozen, and her stomach began to growl, making a sound of protest.

In order to maintain her body temperature, she could only endure hunger temporarily and continue exercising, hoping that the temperature here would rise a little later, or that someone would find her vulnerable.

"Is there any information transmission?" She asked the system tremblingly.

It seems that her ability to understand and use the rules of the world has improved a lot during the two-dimensional transformation, and she was not pulled into the sea of ​​consciousness during the transmission.Several consecutive pictures directly appeared in her mind, showing her the reason for the decline of this world.

It is also unfortunate.The galaxy where this planet is located was originally very stable. Like Yudi's homeland, life gradually evolved during the war between ice and fire.If there were no accidents, under the accumulation of time, a brilliant civilization should have been born here, but the accident happened faster than tomorrow.

The central star of the neighboring galaxy collapsed into a supermassive black hole, which began to approach the star's host galaxy after devouring all the matter around it.

It is not true to say that they are close, but the distance between the two is far enough that they will not affect each other, but after the collapse, the gravitational range of that area becomes larger, so that the entire galaxy is affected.The trajectories of the outer planets are gradually distorted, the long radii are getting longer and the short radii are getting shorter, their orbiting speeds have undergone irreversible changes, and the revolution period of the outermost planets has been stretched to count in millions of years.

The environment of this planet has gradually become extreme. Every year, one tenth of the time is spent in boiling water, and two thirds of the time is spent in extreme cold.But even with the short time the world gave it, life here survived, adapting and thriving in an increasingly polarized environment.

Until they can start to use the environment, transform the environment, and become "them".

But no matter how hard they tried, they couldn't find a way to escape.The galaxy is starting to disintegrate, the flow of time is slowing down, and their civilization is coming to an end.

Yu Di silently read the compressed history and sighed in her heart.Is it because the sky does not allow people to live?it seems that.But the occurrence of all this is nothing but the result of the stacking of all past events, and every event that pushes them to the end is nothing more than a coincidence.If the neighboring star had collapsed earlier, perhaps the civilization here would not have had time to be born; if the mass of the local galaxy was larger, it might not be affected by the black hole.

Such a world is not going to destruction because of human beings themselves. Thousands of words can be summed up in two words: natural disaster.

Yu Di thought of Cheng Die.

Perhaps because she borrowed someone else's body, there is no extra red string on her wrist.Judging from the experience of the previous two times, if Cheng Die also came, he might be among the crowd.She must have known she existed.Eighty percent of the human beings in this world also live underground, in a relatively closed environment. If she can't find herself underground, she might open the damn leather door and peek at the ground.

Of course, it is unreliable to count on this.Yu Di didn't know how Cheng Die tracked her. If something went wrong, would she have to dig holes all the way to find humans?

When the temperature warmed up a bit, she still had to go back to the door and find a way to pry it open or attract the attention of the people below.

Having experienced so many worlds, what Yu Di lacks most is patience.She spent the night listening to the wind and watching the clouds, and the temperature finally stopped dropping.The hole used for ventilation was covered with a thin layer of ice, and extremely weak light came in from the outside.

Yu Di moved her stiff body and crawled out of the snow cave.The originally pitch-black sky was faintly gray, and the gust of wind stopped, and it seemed that it was daytime.

She returned to the door, rubbed her hands, and used the method of digging a snow hole to make a big hole in the ground around the door. It turned out that the door did not exist close to the ground, it was more like the top of a chimney.But the cylindrical part of the "chimney" is still made of the same material as the door, and cannot be knocked.Yu Di looked around it for a while, then opened her mouth and began to chew on the edge of the leather.

The newborn teeth were not very strong, but after she bit and scratched, and rubbed with the gravel from the melted ice, it finally had an effect-it lifted a small edge.
