(This novel is part of a unit. Be sure to read it later. The more you read, the more exciting it will be.) Human beings and alien beasts coexist. Not only are the alien beasts divided into strict grades, but humans are also divided into three, six or nine grades based on their so-called "strength." There are people climbing up this tree desperately. , But they don't know that the darkness under their feet makes them unable to look back in their lives. Some people decide to move to the middle, but the people around them can't see their peace, and the people at the top can't see their leisure. They are too young and don't know that this tree can only go up without pausing. Some people want to settle down and live under a tree, but the tree is too high and they cannot take advantage of the shade. Even if someone on the tree casually drops an object, it can destroy their lives. Only when you reach the top can you take a short rest. The world is inherently dark, and you can only look up to the human heart. In this cruel world, to you I am your everything, but... To me. An article that writes about sweet and sour love under the guise of "rebirth", reflects reality in love, and satirizes ancient feudal society in reality. Bring a little more knife under such content. Warm reminder: Reading this novel may shock your outlook and cause physical discomfort. Please think twice before reading. There will definitely be no errors in the content. If something seems unreasonable, it must be foreshadowing or foreshadowing. Or the character does it on purpose. Everything the male protagonist does is absolutely in line with the character. If you don't understand the dialogue, please analyze it carefully. All the irrational actions and words of all characters definitely have his intentions. I will not write some psychological analysis in the novel, and readers need to understand it themselves. Finally, this novel is purely fictional and does not have any negative direction.
