Liang Ming, a young man from the solar system, unexpectedly transmigrated to a world where everyone is required to participate in dungeon crawling upon reaching adulthood. In the beginner dungeon, he stumbled upon a tattered banner of ten thousand souls, embarking on an unimaginable path. He collected remnant souls, refined spells, hunted demon souls, and commanded ghostly soldiers… Those who opposed him called him a heretic, but only he knew it was efficiency! …Thousands of dungeons, thousands of tribulations, thousands of worlds, thousands of opportunities. He witnessed the wandering swordsmen in the night rain, the end of centuries of grudges. He also saw demons rising like a tide, and heroes standing firm against the tide. His obsessions were too long, and his life too short; he hadn't seen enough, so he invited them all to the banner of ten thousand souls for a reunion. He didn't know why no one ever refused; perhaps it was because he was popular?

He'd transmigrated, and arrived in a world that revered humans as its creators. As a human, Xia Mo should have been excited, but alas… humanity in this world was extinct; he was the only human left, and mechanical lifeforms were also lurking, ready to pounce. Danger! Faced with this perilous world, Xia Mo decided to enter a dungeon. The main world was extremely dangerous, so what did that have to do with his dungeon? Wait, why was the dungeon also in a state of apocalypse? Something wasn't right. In the dungeon, he encountered mechanical monsters, their speed and slow attacks as powerful as monsters, impossible to defeat despite his best efforts. But even so, Xia Mo still wanted to say: Hehe, I must survive! …This is a multiverse story, primarily set in a game world, but other worlds will also be included, as relying solely on game worlds has its limitations. The world-building and other aspects will be integrated into the story, not…

This is a world where games and reality are completely intertwined. Warcraft roam freely, secret realms abound, and dungeons are countless. To survive, everyone undergoes a class change at the age of eighteen.

Lin Mo switched to the universally acknowledged useless class—Heavy Shield Guardian. He could only take hits, had no offensive capabilities, leveled up at a snail's pace, and was the eternal scapegoat in every team.

Despite being treated coldly and assigned the worst resources, Lin Mo remained calm.

Because he awakened the unique talents of [Absolute Conservation of Attack and Defense] and [Infinite Life Drain].

All defensive capabilities are converted into true damage in equal amounts.

Killing any monster permanently increases your maximum health.

"I don't need positioning, I don't need skills, and I don't need teammates."

Lin Mo raised the giant shield, which was as tall as a man, and looked at the roaring beast in front of him.

After exhausting all his might to slay the Demon King, Chu Ming, having cleared the game, found himself unable to exit. The Demon King had just died, and the game was real? What about all the debts I owed, the grudges I'd made, and the girls I'd promised? The good news: he'd inherited the Demon King's flame. The bad news: his level had been reset to zero, and he could only grow by constantly absorbing negative emotions. "So, now I'm both a hero and a Demon King, stuck in two ways?" Six months later, pursued by both good and evil forces, the former hero (now a Demon King) secluded in the forest suddenly discovered he could summon projections of Blue Star players. Thus, the most sinister guild in history was born: Player A: What do you mean the newbie quest is to kill the Four Heavenly Kings of Demon? Player B: Guild Master, that crazy woman from yesterday came to see you again! This time she brought someone else with her. Where are you, Guild Master?! Player C: 996 at the company, 007 in the game, when will this hard time end? - In response to this, President Chu Ming said: Everyone is busy, it's better to be busy... If you are not busy, how can I, the righteous demon king, defeat the corrupt kingdom nobles, wipe out the evil demon remnants, and save thousands of people from danger?
