[Simulator, Unrestricted Simulation, Full Inheritance, Decisive Action]

After Chen Yuan transmigrated to another world, although he didn't have any system or cheat codes, he still managed to live a prosperous and wealthy life thanks to his knowledge from his previous life.

When he was sixty years old, just when he thought his life was about to end, he was murdered by his two illegitimate sons for their money.

In a fit of anger, Chen Yuan awakened the simulator.

Chen Yuan: Simulator? I know it well. Isn't it just about recharging spirit stones or money to get simulation attempts, or completing tasks, or signing in to get simulation attempts, and then getting some rewards after the simulation ends?

Simulator: No conditions required! Unlimited attempts! You'll receive all rewards upon completion of the simulation!

Chen Yuan: Begin the simulation!

On April 1st, 20XX, a massive meteorite strikes Antarctica, and three months later, the "X Virus," also known as the zombie virus, spreads globally. The world quickly descends into chaos as governments lose control and society collapses.

The story focuses on Tang Buping, a young man living a desolate life in a tiny, dilapidated wooden cabin near the Huangpu River. After his mother's death three years prior, he was cast out and has been living like a zombie himself, full of despair. One day, while searching for food, he is attacked by a zombie and barely escapes back to his cabin. Ready to give up and lie down to await death, he writes a final letter to his deceased mother.

However, as he lies on his bed, he unexpectedly awakens the "Lie Flat and Develop" system. The novel follows Tang Buping as he uses this new, seemingly tower-defense-oriented system to survive and perhaps even thrive in the harsh, zombie-infested apocalypse.

…

The roar of lower-level magical elements, the convergence of light and darkness in black and white magic, the rotation of spacetime in higher-level magic. The howls of vampires, the howls of werewolves, the screech of mummies, the curses of witches, the brutality of giants, the evil of dragons, the temptations of demons—all these keep one awake at night. Wands, magical creatures, the Eye of Horus, the life of Genova, the Nephilim hybrid, the Axe of Leviathan, the three Mother Boxes, the Anti-Life Equation, the Infinity Stones—all these things stir the soul. An ordinary person, Fang Zhixing, equipped with a genius system, becomes a Planeswalker. He uses his knowledge of secret psychology, runes, Greek numerology, Egyptian divine blood, and more within the Planeswalker...

The three-year period has come, and the Demon King Mir has completely broken down...

"Who wants to protect the holy city with you? I am the son of the Demon God! I am the ruler of the Demon Clan! Demon King, do you understand? I will kill you all!"

The howling echoed in the church. The Pope smiled but said nothing. The cardinals nodded slightly. Only the new nun was puzzled:

"Mr. Mir...what happened?"

"Shh! This is part of Mr. Mir's plan."

...

Genius Witch: What Demon King? As long as Mir performs normally, the world will become a beautiful world.

Imperial Princess: Demon King? I don't know him. Mir is my eternal light. No one is allowed to compete with me!

Blood Princess: Demon King, don't be discouraged. Let's change positions and do it again! ...
