Invincible from the Moment I Saw the Boss's Health Bar

I feel the title should be changed to "When I See the Health Bar, I'm a Grandson." Invincible my foot! It lacks the satisfying feeling of "Extreme Demon King" by Gun Kai. The protagonist is a grandson the whole time, constantly adding points to his mana.

To sum it up: Run! Run! Run! If we're using a 5-point scale, a typical novice writer would give this book a 2, but it'd be a mere 2.5-3 At best. This book is categorized as a virtual reality game, but now I'd prefer to classify it as a game (system) fantasy world with a tiny bit of urban elements.

The landlady is dead, and Ding Hui is gone too. No one in the real world can be trusted, and in the game, neither humans nor demons are trusted. So, you're just fighting the whole world alone and then wallowing in self-pity? What are you even writing?

I've read over 140 chapters now, and this second sister is such a nuisance. Please reduce her appearances! Every time she appears, the plot becomes incredibly drawn out, and her interactions are terribly awkward. Or, she should just find the eldest brother and have him take her away. Having a player tied up by an NPC is a waste of time and energy, haha.

The landlady's personality is just outrageous. And then, the protagonist's personality of sacrificing himself to save others is very illogical. Then there's the orthopedics aspect? Playing a game is supposed to improve real life, but the protagonist wastes development time and money on NPCs—it's ridiculous.

I thought it was a wish-fulfillment story, but it wasn't. The beginning was pretty good, but it went further and further off-topic. Although he did get stronger, he mostly relied on others risking their lives to save him in major events, and he could only bully those weaker than himself.

He was asked to infiltrate the demon realm, but what did the protagonist actually do? Not a single piece of information was given from beginning to end... They pay him a salary, provide him with housing, give him status, and keep his information confidential. The protagonist discovers the demons' movements. Protagonist: "Now I can farm some resources and level up, haha!"

Is it really possible for anyone to finish a book without using their brain? Or is it written for mindless readers? The data is so good, I gritted my teeth and read up to chapter 27, what kind of garbage is this? Is writing books that lucrative?

Current confirmed information: Humans: Flowers, plants, and trees Demons: Cold, heat, withering, flourishing Spirits: Wheel of thought, hollow pearl, wisdom Humans killing others generate malevolent energy that attracts demons; demons killing others generate demonic energy that attracts spirits.

Because of this idiotic second sister character, at least half the readers left after reading the first 200 chapters.
