The Formula for Combining Monsters

I really dislike this main character more and more the more I watch him; when it comes to exploiting others, he really goes all out to fleece them. Logically, after doing this to him, he would definitely ask his family for money to pay the protagonist. His parents would easily sense something was wrong.

Dear author, I believe that as long as you write seriously, this book will definitely become a masterpiece. Not for anything else, just the "Nine Star Poisonous Milk" alone—the subject matter is novel, the style is humorous, and the content can be diverse.

I've read up to chapter 103. It was clearly stated that the system wouldn't backfire when controlling monsters, but it backfired when it crossed a level! Even though it was a major realm difference, it shouldn't contradict the established rules! This is so annoying! Such a powerful system can't even control the monsters it created?!

Monster/Furious Characters thread, feel free to add.

This protagonist is really unlikable. Has he never seen money before, or mecha? He's always trying to take advantage of others and constantly targeting them. It gets disgusting after a while. His personality alone is enough to turn many people off.

In the 21st century, with current technology, humanity can build space stations that can stay in space for extended periods. So, author, do you think it will be possible to build a lunar base in a hundred years? One Oxygen Destroyer can damage Godzilla, so author, how many weapons do you think humanity will be able to create that are more powerful than the Oxygen Destroyer in 100 years?

I just saw a story about a female lead being used as a tool, so I want to ask, in real life, what kind of orphans do you treat women as?

Earth Defense Force

The moment I saw the best friend character at the very beginning, I didn't understand why I had to include a best friend character, especially since she was a time traveler. I could already imagine that later in the story, her best friend would encounter difficulties, and I would help her solve them. Just like many people don't like having a female lead, why would I need this inexplicable best friend?
