Transmigrating to an alien world and becoming a low-class serf, Monroe felt this was a tough start to life. The dilapidated house leaked, the black bread grated on his teeth. Human rights were a thing of the past. Until a translucent, illusory panel popped up before his eyes: [Farming Skill Experience +1] [Current Farming Skill: Beginner (7/1000)]… Countless years later, analyzing gods and demons, nurturing insect swarms, and becoming a narrator, Monroe said: “Now it’s time for the universe to listen to me…” An alien soul, an immortal epic.
Someone once saw me at the end of the world and reverently called me the World-Entwined Serpent - Jörmungandr. Someone also once gazed upon me from the end of Hell and called me the Ancient Serpent - Satan. I was also feared by the gods and called me the Hundred-Headed Dragon - Typhon. I have had many names: the Serpent of Creation, the Serpent of Sacrifice, the Serpent of Ritual, the Serpent of the World... But after crossing Chaos and reaching the Primordial Realm, I have only one divine name - the Primordial Ancient Serpent, the Origin of All.
When Ji He first transmigrated, she thought she had landed in a tycoon-building storyline. She threw herself into making money, dreaming of counting cash until her hands cramped.
But then—plot twist—it turned out to be an apocalypse survival script.
She wanted no part of it.
But what could she do? Better a miserable life than a glorious death.
So Ji He went full survival mode: working by day, digging tunnels by night, and diving into dungeons whenever she had time. Her motto? If it won't kill me, I'll scavenge it—if it might kill me, I'll still try. She crammed everything she could into her inventory space.
Before she knew it, she had somehow turned a doomsday survival game into a business management sim.
Good news: I have traveled through time.
Bad news: I have traveled through time to the world of the Lord of Mysteries.
Good news: I am familiar with the plot related to mysteries, although not all of them.
Bad news: I seem to be the backup of Tianzun, and I have a fundamental conflict with the protagonist. It's either you die or I live.
But these are not important. The important thing is that I was forced to drink the "Assassin" potion just after I traveled through time.
Two bottles!!!

Traveling through the ancient times, Cang Xuan became a hollow willow tree in Kunlun Mountain, accompanied by the [Dao Compass], which can deduce martial arts, calculate the secrets of heaven, and understand cause and effect.
He knew very well that the world was vast and that all people below the level of saints were ants.
During the first catastrophe of Longhan, he was in seclusion; during the war between wizards and demons, he was planting trees; during the catastrophe of Conferred Gods, he was still deducing his own path in the cave.
He never takes the initiative to get involved in cause and effect. He always plans everything carefully before taking action. With his endless lifespan and patience, he silently makes plans.
Billions of years later, when the saints thought they had control over the world, they looked back and found that the willow tree rooted in Kunlun had already unknowingly covered the entire sky of the ancient world.

What should I do if I travel through time and space and become a fat otaku?
Masao Tanaka was extremely desperate. He had traveled through time. It would have been fine if his name and family were strangers, and it would have been fine if he hadn't been given a handsome face.
But why did he become a typical fat otaku like someone from an anime?
Fortunately, there is a system, but why is this system called the [Degenerate System]?

Goto Ichiri: "Tanaka, best friend."
