The aliens came with hostility.
Facing the invasion of aliens, human beings are weak like ants.
So this is the end, the real end.
But there is resistance when there is an invasion.
For some, this is not the end, it is war.
So this is war.
Real war!

Zhong Yansheng lived for eighteen years. After accidentally falling into the water, he dreamed and found that he was living in a book. In the book, he was a fake young master who was mistakenly adopted by the Marquis. After the real young master came back, he {real} was not taken seriously by the family and was driven to a separate courtyard in the suburbs of Beijing. His parents only doted on him {fake}, and they turned the real young master into a black hearted man, and finally his family was ruined. After waking up, Zhong Yansheng learned the news that Master Zhen returned to the house three days ago, but the whole family only revolved around him {fake} who was sick.

There once was a very popular question on the internet:

If one morning, you woke up and realized that your gender had changed, what would be your first reaction?

And someone on the internet had famously responded:

First, give your bros a good time!

Su Jian remembered that when he saw this reply, he had slapped the table to express his admiration. What a good bro! Such loyalty!

But now that he actually encountered this strange situation himself, he could only feel an extremely ball-breaking alarm, shocked grief, and frightened anger. **** your mom! Ah, ****! **** it!

Oh, a correction. The above is grammatically incorrect. After all, poor Classmate Su Jian doesn’t have balls anymore.
