I started with Demon Slayer, and after drawing the strongest character, I'm invincible!

After 666 and the other five woke up, they told him about the emergency rescue mission and then waited for his reply.

Gojo Satoru thought for a moment and said, "A distress mission? Sure, just tell 888 I've accepted this mission."

So this is how you enter a mission world? When did 888 start caring about this kind of thing?

"Okay, by the way, Wu, check our account balance, there's a surprise!"

When Gojo Satoru heard 666 say that, he knew that the world had gained a huge amount of energy points again.

He now understands why 666 is called an energy collection system; so that's what "collecting" means.

Collect all valuable items in the mission world and then exchange them for energy points in the shop.

Therefore, there is no penalty for not completing the tasks issued by the task system, because the energy points obtained from completing tasks are not their main source of income.

He didn't feel anything looking at the string of zeros in his account balance; to him, more energy points were just a number.

He can usually accomplish whatever he wants on his own, and he rarely uses energy points except to buy snacks.

666: "My host has agreed to the mission you mentioned. Please teleport us there later."

888: "No problem, I'll give you a 30% discount on the skin you're planning to buy."

Upon hearing this good news, 666 immediately opened the system skin sales interface. It had already saved up enough energy points, and could save some money if there was a discount.

With a flick of its claw, its balance was almost empty. Its heart ached; the energy points it had just acquired were gone. (This is 666's own account, and has nothing to do with Wu's account.)

However, seeing its sparkling new skin cheered it up; Wu would definitely like its new look.

888: "Ready? We're about to begin the teleportation."

666: "That's fine."

A halo of light emanated from Gojo Satoru and 666, and they vanished instantly.

After sending the person to the mission world, 888 finally breathed a sigh of relief. The situation in that world was terrible; if no one could be found to take on the mission soon, that world would be destroyed.

-

"666? What kind of look is this?" The moment he entered the mission world, Gojo Satoru noticed the difference in 666.

"Hehe! This is my new skin, what do you think? Does it look good?"

666 flapped its little wings and stared at Gojo Satoru with its big, bright eyes.

"It looks great! I love it." Gojou Gosho 666 gave a thumbs up; its new look was a Pikachu with wings.

What genius came up with this new image? An electric mouse with wings—that's much rarer than QB.

However, remembering that it was Merlin who gave 666 the QB skin, he actually thought it was quite reasonable.

666 excitedly flew around Wutiao Wutiao once, it knew it! Wutiao Wutiao would definitely like its new look.

-

The streets were shrouded in black mist, and a giant Ferris wheel could be vaguely seen in the distance. Unidentified monsters also roamed in the black mist.

"Tsk, what are these things? Zombies? Or mutated species?"

Gojo Satoru captured a monster wandering in the black mist. He couldn't understand what this humanoid creature, which looked like a zombie but also possessed the ability to think and superhuman strength, was.

"I understand. These creatures are all around us. According to the system's detection, they were originally humans."

666's voice sounded serious; the situation in this world was dire.

"So they mutated from humans? 666, go and analyze the composition of the black mist."

Gojo Satoru keenly sensed that something was wrong with the black fog that permeated the air, and that this black fog was spreading throughout the entire city.

"According to system detection, this black fog is not only toxic, but also contains unidentified substances that are infectious."

666 Now I know why the black mist is full of monsters that were transformed from humans.

They were transformed into this state by the black mist, and they attack all living things around them.

Did 888 explain what the situation is like in this world?

Gojo Satoru found a high vantage point to look into the distance, where all he could see were buildings and mutants shrouded in black mist.

He saw no sign of any living people; the city was like a dead city.

"Wait a minute, let me ask."

666 had seen the information provided by 888 before, but it only said that the world is facing huge problems.

The mission's task is to prevent the world from going to destruction; nothing else is mentioned.

666: [What's going on here? Do you know? Attachment: Photo x1.]

888: [I'm sending you the information. It was written by the original mission taker of this world.]

666 fell silent after seeing the information sent by 888. It really wanted to ask, "How could someone make such a big mess?"

"I realize that this black fog is not just shrouding this city, but has spread all over the world."

The black fog is an infectious virus formed by foreign substances combining with biological experimental samples from a local research institute.

Gojo Satoru frowned. Didn't this mean that humanity in this world was already wiped out? Then what was the point of having him come here?

"and then?"

666 paused for a moment before continuing.

"This black mist appeared suddenly. There was originally a mission taker in this world, but his character was a homebody who liked to sleep."

"The world's trajectory has been running normally, so he has been sleeping all along."

Then when he woke up, the black mist had already appeared, so he tried to find a way to remedy the situation.

Upon hearing this, Gojo Satoru had a row of question marks above his head. Did that person really try to find a way to fix it?

"So what did he do? His remedy was that the whole world was doomed?"

"Well... not everything is finished. He has gathered and protected the main characters of this world, and they are in this city."

He also wanted to find items to dispel the black fog in the system shop, but he was just a newbie and didn't have any energy points or access permissions.

"But he really wanted to save the world, so he bought a god-level item card [Time Reversal] on credit."

Gojo Satoru glanced at the city shrouded in black fog, somewhat doubting the authenticity of the information 666 had obtained.

The god-level item card [Time Reversal] sounds incredibly powerful. If that mission taker actually used it, how could the world still be like this?

666 noticed Gojou's gaze and fell silent as well, understanding its host's thoughts.

"Ahem, the item card thing is true. He originally planned to turn back time in this world to before the black mist appeared, and then wait for the black mist to appear before capturing it."

"But... something unexpected happened..."

It didn't know how to continue, because what happened next was really too incredible, making it wonder if the person who carried out the mission was an idiot.

"What kind of accident?" Gojo Satoru raised an eyebrow. What kind of accident could have caused the item card to fail to work?

"His hand inexplicably trembled when he used the item card; he used it on the wrong target."

"He reversed the timeline for all the main characters, so now the entire main group has become children."
