Answer 1

"I've read this novel before" was a fantasy novel written by the author, Eight Colored Cat. The general plot of this novel was:

My new book, My Invincible Animal Legion. Please support me! [Hot-blooded and refreshing, easy and funny!] In one transmigration, Lu Wange realized that she had transmigrated to a novel that she had read in her previous life. It was a novel that tormented the main character for pleasure. She was the main character! He wanted to see how Lu Wan 'ge would rely on the memories of his previous life and the Madman System to test the waters at the edge of danger again and again, change his fate, help him get rid of his cuckold, and seize the opportunity of being a villain! He also opened a chain restaurant, a pet hospital, and specialized in treating the infertility of some top-notch mighty figures. There was no other way. Nine dantians and nine yuanying required spirit stones, and the expenses were too high. He could only start a side business to earn money. Not to mention that there were various gods and Buddhas who wanted to kill him. How could he become stronger without earning spirit stones?
