I don't know why, but I was walking on the way to buy breakfast and remembered more than twenty years ago.

That's right, at this moment, I'm actually going back more and more.

I seem to be the same now as I was when I first worked as an assistant to Dark Clouds.

Bags in his hands, steamed buns, flower rolls, and hot soy milk were carried back to the planetarium.

One of the two PhDs in physics counted, and the other looked at the computer to look up something.

The clouds were thick and it seemed that he had talked to Mayor Lixia.

I leaned over and listened, and the conversation was not about the end of the world, but about me chasing Wusu.

Mayor Lixia nodded his head with admiration, and the dark clouds covered the clouds, and said that there was a lot of fun to say out of nothing. said that I was the first in the family, and I served their family in order to marry Wusu. What I said is reasonable, I am not the party and almost believed it.

But if I think about it carefully, isn't the number one in the family a big fat black cat? And I really want to take care of the black cat for a while, and I'm almost holding it to the toilet, and it's cloudy, how to put these things on myself.

Seeing me, Dark Cloud waved and said with a smile, "Yes, Luqiao." What I just said, right? ”

"Yes, Dad, you're right." I nodded my head, and at this moment, even if the clouds were covering me, I could only say yes.

Lixia gave a thumbs up on the side and said with envy: "My family is also a daughter, and she has just entered junior high school. When the time comes, I hope I can make my son-in-law bow down like you. ”

I smiled wryly and handed the food to the clouds, followed by two physicists.

When I handed the bag to Lixia, Lixia put one hand on my shoulder and said, "It's not good to be a son-in-law, I remember that I was treated almost the same as you were a few years ago." ”

I shook my head and said, "Mayor Lixia, do you have a cat at home?" ”

Lixia was stunned for a moment and said, "A puppet, what's wrong?" ”

"It's okay, you'll be the same as my father-in-law. Good luck with a good son-in-law, really. I smiled and picked up the soy milk on the table and took a sip.

"I lend you good words." Lixia said with a smile.

Chen Hao raised his head and said, "It's calculated, the very center of the earth." The impact area is 234 million square kilometers, and you must know that an atomic bomb is only 3,257 square kilometers. Probably more than 70,000 atomic bombs spread the power of the fall in parallel, which is still a conservative estimate. ”

"Ahem, you can say it straight. The total area of the earth is about 510 million, and this meteorite has affected at least half of the world. Han Dong said.

"I'm sorry, I always like to use metaphors. Han Dong is right, that is, the area of almost half the world is really unimaginable. Chen Hao said.

"Wait, what about a meteorite?" Lixia said puzzled.

I'm glad that Rixia said what I wanted to say the most.

"This is only a calculation of the approximate contact area and the aftermath of the impact, not whether it will run through the entire Earth. An asteroid with a diameter of 400 meters and an orbital speed of 30.728 kilometers per hour. This velocity, not counting the acceleration of the attraction of the Earth's magnetic field as it approaches the Earth, I now hope that all of this is fake. Chen Hao said.

"I figured out that the best-case scenario would be for the Earth to be smashed out of a huge crater. The aftermath covers half the globe and will translate the planet by some distance. If we are lucky enough to survive, the Earth will become closer or farther away from it, and the weather will become hotter or colder. Of course, this is also what you have to face after surviving, not including other unexpected variables. Han Dong said.
