As Sukuna in Invincible - Chapter 35: Compass

The Blood Warrior of the Ungpae Association, who created a sea of blood wherever he went, made the world of the Forces of Evil possible.

The Nine Great Sects and the Six Great Clans joined forces to fight him, but were unable to stop him.

Four Great Warriors, who were Murim’s last hope, appeared.

The four of them fought against the Blood Warrior and eventually defeated him at Mount Song.

The time has come for the legacy of the Blood Warrior to rise once again.

Due to an unexpected turn of events, Xia Fei consumed a Super Gene Optimization Fluid that bore no brand, expiry date, instructions or stated its place of origin.
Our story begins here…

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor.
At 3 am, Chen Ge held a cleaver in his hand as he hid beside the room heater. The call he was trying to make was finally answered. “Landlord, is this what you meant by ‘the house can be a little crowded at night’‽”

When Li Yu woke up, he found that he had traveled to the game world of “Avenue Eternal”.

At this time, there is still half a year before the player arrives.

The evil demon catastrophe has not yet begun, and the forbidden areas of death such as the rotten swamp, the golden desert, the ghost country of the Yinshan Mountains, and the boundless monster sea are still silent. The whole world is calm.

Li Yu took advantage of his foresight and took advantage of the opportunity to develop wretchedly.

After the game is launched, along the Qingshui River, players often see a senior NPC with a glittering ID fishing.

Whenever the players approached excitedly to chat to see if they could apprentice or trigger tasks—

“What? You want to worship me as your teacher?”

Li Yu shook his head: “Excuse me, your qualifications are too poor. But Pindao once lost a Chilong jade pendant in the zombie cave. If you find this thing, I can teach you a spell.”

“Do you want to learn alchemy?” Li Yu smiled slightly: “There is a group of evil cultivators in the Wugui Cave of Qilao Mountain, as long as you can eliminate the evil for the people, and bring their magical instrument Xinjin and copper bottle to me, How about Pindao passing on your alchemy skills?”

“You want to worship Zixia Sect?”

“Do you want to learn alchemy?”

“It’s all right.”

Li Yu said meaningfully:

“But you have to understand one truth, there is no free lunch in this world!”

…

It was not until hundreds of years later that many top figures fell and disappeared, and the players also changed one after another, but Li Yu was still active in the world of dry ground, and he was even about to rise through calamity.

Many players have to sigh: This NPC is too strong!
