ASFUCITWON Chapter 159: Flying Ship

Reiji's research into Chakra for the past month had yielded results that were… almost nil.

Where Reiji had already guessed that researching energy like Chakra would not be as easy as turning the palm of his hand, but still, frustration began to cloud Reiji's mind.

Chakra was energy, and changing one form of energy into another was no simple matter.

It was not something that could be done simply by theory, and while it was not impossible, its realization was far more complex than Reiji had imagined.

For example, Senjutsu Chakra could be created by combining one's own Chakra and Natural Energy, provided one was in Sage Mode.

That was the only concrete example of a change in Chakra type that could be directly observed. But other than that? There had been no significant progress.

Reiji could indeed change regular Chakra into Senjutsu Chakra—but changing Chakra into something completely different? That was still beyond his reach.

So far, every theory Reiji had tried to apply had only ended in failure.

Where Reiji had tried to manipulate the structure of Chakra using various methods, channeling it through specially designed seals, even experimenting with various energy conductor materials.

However, none of them gave the desired results.

In the end, for an entire month, all Reiji found was a dead end.

Changing the type of Chakra was not something Reiji could do now.

It would probably take years before Reiji found the answer.

Therefore, Reiji decided to stop wasting time on something that was still out of reach and shifted his focus to something else—something more tangible, something that Reiji could create with his own hands.

...

...

Time passed quickly.

Three months had passed since Reiji shifted his research focus.

Now, Reiji was busy with a new, even more ambitious project—making a Flying Ship.

Not a plane.

But a ship, a real ship, that could float in the air like the flying ships in fairy tales.

How was that possible?

A simple question, but the answer is more complicated than it seems.

What makes a plane fly? Technically, there are many factors.

Planes have wings that create lift, engines that provide thrust, and complex aerodynamic balance.

However, Reiji is not an aeronautical engineer.

He does not have a deep understanding of aerodynamics, and it is too much trouble for Reiji to research such complex technical details.

So, Reiji chooses a simpler approach that is more in line with his current world.

What if a ship could fly without wings?

In his previous life, while still on Earth, Reiji had seen many objects that could fly thanks to the manipulation of mystical energy.

Swords that floated in the air, witches' brooms that could carry someone across the sky, even ships that could penetrate the clouds.

Reiji himself had used a flying bicycle when he was still on Earth—an experience that proved that there were many ways to outwit the laws of gravity.

However, in this world, in the world of Naruto, Reiji had to find a new way to make it happen.

Where Reiji could not rely on magic techniques or modern devices.

The key was Fuinjutsu.

For the past three months, Reiji had devoted his time to researching how to create a levitation effect using Fuinjutsu.

The first step was to understand how to make an object float.

After days of research and experimentation, Reiji realized that the solution lay in the weight of the object itself.

If an object was light enough, then only a small push was needed to make it rise.

Thus, Reiji began to develop the concept of Weight Reduction Fuinjutsu—a seal that could seal away part of an object's mass, making it lighter than air.

However, theory alone was not enough.

Reiji needed to test it on a real object.

Where Reiji chose a small boat belonging to one of the fishermen from the Uzumaki Clan as the test subject.
