In the Beginning, I Depended on Opportunities to Survive.

[Seize opportunity + system + no heroine] Chu Xun traveled through time and entered a world where the weak eat the strong. But there are many irrational people in this world. If you take a few steps, you will have an opportunity. This is unfair, but the world is inherently unfair. Therefore, Chu Xun wants to fight to the death with those so-called "protagonists". Be your own protagonist! (The author's first book, the previous ones were all published a year ago, and I didn't bother to overhaul it. I added an ending, so it's considered bad. It's highly toxic, and the writing style of an elementary school student)
