Merlin said goodbye to the professors at the school one by one and returned to his room.

Then he lit the fireplace, took out a handful of Floo powder from the space ring, and sprinkled it in.

Although the fireplace at Hogwarts School is not connected to the rest of the world, this is not a problem for Merlin.

After a closer look, he connected the fireplace in his room to a makeshift network passage that led to the Leaky Cauldron Bar.

"Leaky Cauldron Bar!"

Waiting for the flames in the fireplace to turn green, Merlin called out the name clearly, and the next moment teleported to the room of the Leaky Cauldron.

"Very well, then, it's time to move on to the next world."

After confirming that no one was tracking, and taking control of the world, the tree opened a bubble and opened a passage to walk in.

……

Inside the laboratory of the Clausburg Arsenal, 1942.

"Are you ready, Dr. Zola?"

A magnetic voice sounded, it was a man in a German ** military uniform, looking up the information, while talking to the scientist who was fiddling with the machine.

"This instrument requires incredibly precise calibration, and I beg your pardon that I had to make sure it was foolproof."

The scientist was short in stature and his whole head was like a potato, and Zola, who looked like he was extremely smart, replied.

"Are you sure those soldiers can withstand this surge of energy, can they accept this transformation?"

The man in military uniform kept flipping through the documents in his hand, which also described some ancient legends of Norse mythology, as well as some experimental photographs.

"I can't be sure of anything in front of this device, and I'm even worried that it won't work at all."

Dr. Zola walked over from a machine, pushed his glasses and looked at the officer in front of him, John Schmidt.

He was working in Switzerland some time ago, but for some reason he was invited by the leader of the Führer's right-hand man, the Hydra, nicknamed "Red Skull".

He was confused, but as the chief scientist of Hydra, it was the same everywhere he studied, and he didn't mind working in a different place.

Schmidt did not respond to Dr. Zola, but took out a box from the toolbox next to him and slowly opened it.

"It's ???"

A blinding blue light emerged from the box, drawing Dr. Zola's gaze firmly.

Schmidt picked up the blue cube in the box and placed it in the machine next to him.

As a scientist, Dr. Zola knew that that might be what he was here for.

Then I quickly put on my blindfold, came to the console, and slowly started the machine.

"Twenty percent...... Forty...... Sixty percent...... Stable at 70 percent! ”

He looked nervous, constantly increasing the power of the machine, and stared closely at the numerical display on the instrument panel.

"I've put all this effort into it, not for safety, doctor."

Schmidt seemed to lose his patience and walked over to push Dr. Zora away, then took matters into his own hands and pulled the power up to the maximum.

"Buzz"

The machine that stored the blue cube made a buzzing sound, and it seemed that the next second it would start to explode beyond its control.

"Buzz"

One force after another from the blue square began to impact the surrounding machines along the line, dyeing the entire space blue.

"Click"

Suddenly, Schmidt and Dr. Zora heard a clicking sound at the same time, as if it were the sound of glass breaking.

……

Merlin is now stepping onto the passage of the fifth world bubble.

I don't know if it's unlucky, or if that's what it's like to travel through the world normally.

When he confidently stepped on the first world bubble, he thought it would be a familiar world again.

As a result, he almost died there, because it was a world that was close to destruction.

In addition to the lava flowing on the surface, there is also a crater that is spewing lava and poisonous gases.

Not only is there no life, but not even a trace of magical elements has been found.

He couldn't survive without air and magic, and when he first stepped into that world, he would almost not have come back if he hadn't had an elemental shield hanging with him and immediately opened the next passage.

The second world is even worse, it is also a magma world, and there is magic and air in existence.

Just when Merlin thought it was a world worth exploring, a roar rang out in the distance, shattering his elemental shield directly.

Even the sound waves that came from him hurt him so badly that it was unimaginable to imagine a terrifying creature.

After he returned with his seriously injured body, he immediately sealed the passage of this world with the World Tree.

If it weren't for the fact that he didn't have the ability to cut off the branch that connected the bubble tree to the world, he would even want to cut off this branch.

Because the plane passage opened by the World Tree is bidirectional, when the branch pops the bubble to open the passage, the other side can enter the passage in reverse as long as it is strong enough.

As for how powerful it must be to open the passage to the World Tree, Merlin doesn't know.

At the same time, he often dares to plant branches indiscriminately in some worlds without being too powerful.

But just like the world just now, a roar that didn't know what kind of existence was so far away.

directly injured him as a master magician, and it stands to reason that there is a stronger existence than this.

Therefore, he directly blocked that world, without him, he couldn't be provoked, so he was respectful first.

After recovering from his injuries, he did not give up the act of traveling through the world, and it was not his style to give up when he encountered some small setbacks.

Then he stepped into the third and fourth worlds, fully armed, and the results disappointed him.

There are no traces of the existence of magical elements in two consecutive worlds, and even civilizations are relatively backward eras.

A world that was in the middle ages of ignorance, and it was also an era when ordinary people burned them as witches.

The other is the era of primitive tribes, who hunted wild beasts and gathered wild fruits for a living.

After observing silently for a while, he found that it was indeed a world of ordinary people, and then left.

These two worlds were also blacklisted by him, worthless, no mystery, and backward technology, which is very boring.

After a few rests, dressed in a black robe, his body exuded the power of magic, and there was a layer of nine-colored elemental shield outside in the flickering Merlin stepped on the steps of a new world.

Merlin didn't know if the world was in danger or not, but it was always a good idea to be prepared.

"Buzz"

A passage emitting pitch-black lightning opened in a room, and Merlin slowly stepped out of it.

But the next moment, he was caught by a blue square that was emitting energy.

"What is this??"

Soon he moved his gaze to the side, the two men who were staring at him.

Merlin looked at the officer-looking guy and felt that his uniform was pretty cool, and then he saw a familiar sign on his left chest.

A skull marker with six tentacles sticking out like an octopus underneath.

"This is the Marvel ?!!"
