The cultivation base is returned ten thousand times, and the starting strength is at the Four Empero

Ning Chuan slowly stretched out his hand and casually drew it in the air.

The next moment, a space door leading to the One Punch World headquarters building appeared in front of everyone.

This door is like a crack, through which you can see a completely different world.

"I'll be back in three days. If you've made up your mind, gather here!"

After leaving this sentence.

Ningchuan then took Nezuko, Tanjiro and Tamayo and disappeared in front of everyone in an instant.

They disappeared so quickly, it was as if he had never appeared!

The other members of the Demon Slayer Corps were shocked when they witnessed all this!

They knew that Ning Chuan's strength was beyond ordinary people, but they didn't expect that Ning Chuan had the terrifying ability to cut through space!

This is almost an ability that only gods in legends have!

Just when these people had not yet come to their senses.

Ningchuan has already taken Tanjiro, Nezuko and Tamayo through space and returned to the One Punch World.

The next moment, several people appeared inside the One Punch World headquarters building.

The interior of the headquarters building is filled with various high-tech equipment.

The three people who came here were a little at a loss.

"Let's go, let's get down to business first!"

Ningchuan smiled and rubbed Nezuko's head.

Then he took them to the laboratory inside the building.

Vegapunk and several other scientists are busy in the laboratory.

When they saw Ning Chuan coming with a few people they had never seen before, they immediately stopped what they were doing.

He trotted to Ningchuan's side.

"I brought you some interesting experiments."

"You guys have something to do during this period of time!"

Say it.

Ningchuan handed the two halves of Muzan's body to Vegapunk.

At the same time, he opened the Gege world and rescued the Twelve Kizuki who were badly beaten by the guys in the Pirate World.

Ning Chuan explained the origins and abilities of these ghosts to Vegapunk and the others in a very concise manner.

He described in detail how Muzan transformed from an ordinary human to the Demon King he is today.

And how he used his abilities to create powerful ghost tribes such as the Twelve Demon Moons.

It also briefly introduces the abilities of each ghost, especially the special abilities of the Twelve Ghost Moons.

"Is it a new ability other than the Devil Fruit ability?"

"Interesting!"

“It’s even a new species!”

"Ningchuan, have you been to another world again?"

A hint of excitement flashed in Vegapunk's eyes.

He could already feel that these ghosts contained great research value.

It may even allow the Science Department to develop a new research direction!

Vegapunk was very excited at this time.

Several other scientists also turned their attention to these ghosts.

They couldn't wait to start cutting up the ghosts for research!

Ning Chuan looked at their reactions and nodded with satisfaction.

"This is Tamayo, who used to be a demon under Muzan."

"But she has been able to break free from Muzan's control and has done some research on ghosts."

"I think she should be able to provide you with some help, so let her start from the most basic researcher!"

When Tamayo, who was standing by, heard these words, she couldn't help but feel touched.

She used to be a member of the ghost tribe, but now, she stands in the new world of the Science Department.

Be able to participate in a larger plan.

I can also study Wuzan carefully!

This made Zhu Shi very grateful to Ningchuan!

"You know as much about ghosts as any expert here,"

Ningchuan patted Zhu Shi's shoulder, smiled and continued.

"However, your professional knowledge still needs to be improved. I will arrange for Vegapunk and the others to help you with training."

"You have the potential to become a top biologist!"

"Come on!"

Tamayo nodded, her heart filled with gratitude.

……

After arranging Tamayo's affairs, Ningchuan took Tanjiro and Nezuko to other places in the headquarters.

Their next stop was the Swordsman Association.

This association was co-founded by two great swordsmen, Hawkeye and Shanks.

There are many swordsmen from the pirate world registered here.

Ningchuan knew that here, Tanjiro could receive more systematic training and learn more advanced sword skills!

As the child of the world in Demon Slayer.

Although the upper limit of Demon Slayer's world level is not high, he is the son of the world after all.

Ningchuan believes that Tanjiro must have made great achievements in this world!

After making arrangements for Tanjiro.

Ningchuan took Nezuko back to his office.

He decided to bring Nezuko to the female hero group and let Momoka, Hancock and others take good care of her and help her train and grow.

When Ningchuan brought Nezuko to the female hero group.

Hancock couldn't help but smile when she saw this petite and cute girl.

As the leader of a group of female heroes, she naturally feels a sense of accomplishment as she sees her team growing stronger.

And Hancock knew that Nezuko must be from another world.

The fact that Ningchuan was able to bring her back means that Nezuko must have something special about her.

"Another beautiful little sister."

"Come and tell your sister, did that bad guy Ning Chuan bully you on the way here?"

There was a sly glint in Hancock's eyes.

"No, no."

Nezuko's face instantly turned red when Hancock teased her.

Ning Chuan couldn't help but rolled his eyes and said with dissatisfaction.

"Hey, hey, hey, how can you think so badly of others?"

"I've never bullied anyone, okay!"

Hearing this, Hancock couldn't help but smile charmingly.

"You've never bullied anyone?"

"You bullied me so much the past two days that I couldn't get out of bed the whole day!"

……

Soon, it was already evening.

As Ning Chuan expected, Hancock took advantage of the fact that everyone else was asleep.

He secretly came and attacked Ningchuan at night.

However, Hancock's strength is still too weak.

After a few rounds, Ning Chuan surrendered!

When the two were in a warm moment, Hancock began to tell Ningchuan about the changes in Yiquan's time during the two days he was away.

Since defeating Boros.

Recently, many members from the Hero Association have begun to come to the Hero Association of All Worlds to visit and learn.

These include metal baseball bats, sexy prisoners, and even Bang Gu brought his senior brother to visit and learn.

Of course, except for these S-class heroes.

Many heroes of other levels also came.

It seems that after defeating Boros last time, the Heroes Association of All Worlds has become completely famous!

"Let them study as much as they want. When the Hero Association goes bankrupt, they will come to us."

Ning Chuan said with a smile.

Obviously, he didn't care about these people from the Hero Association coming to him to steal his skills.

Anyway, these people will definitely not be able to learn all the things he has here!

For example, the various breathing methods I brought back this time.

This is not very useful for heroes above level B.

But for ordinary people below level B.

But it is a combat skill that can greatly improve your skills!

Those who want to become stronger will not be rejected!

In the future, he will go to other worlds and bring back the cultivation methods from other worlds one by one.

Continue to expand the ability library in the Heroes Association of All Worlds!

If possible, he even wanted to merge all the worlds he had visited into one world.

Let these worlds be under your rule!
