Chapter 5: Training Plan

The effect of consuming the Glint-Glint Fruit is to transform one’s physique into light, completely elementalizing into photons, rendering any ordinary attacks ineffective.

At the same time, it grants the ability to move at the speed of light and emit laser beams from the body, causing considerable damage.

Of course, the ability of the Glint-Glint Fruit is not weak, but mastering the power of this fruit is not an easy task that can be accomplished in a short time.

Yu attempted to move at the speed of light for ten minutes.

During this time, he manipulated photon energy, emitted laser beams, and even tried to use combat techniques like Admiral Kizaru’s from the world of One Piece, such as Light Speed Kick, Yasakani no Magatama, Yata no Kagami, and Ama no Murakumo.

However, without exception, they all ended in failure!

“Hoo~”

Yu let out a long breath, wiping the sweat from his forehead.
“Indeed, mastering the abilities of the Glint-Glint Fruit is not an easy task… For now, I’m somewhat skilled in using the speed of light for movement, but as for the rest, I can only emit some unstable laser beams, which are prone to veering off.
When it comes to Light Speed Kick, I’m still not proficient enough in controlling the power of light.
There have been a few times when I even missed the target.
As for the higher-level techniques, let’s not even talk about them.
It seems like starting tomorrow, I need to create a dedicated training plan for myself!”

Any power cannot be perfectly mastered as soon as you acquire it unless you are an extraordinary combat genius.
Yu certainly didn’t consider himself to be such a genius, so training was a necessary task.

However, before training, there was one more thing to confirm!

Yu arrived at the small lake inside the school.

Looking at the crescent moon reflected in the lake and its shimmering moonlit glow, he took a deep breath.

Devil Fruit users all have a significant weakness, which is fear of seawater and Seastone.

Naturally, the Marvel world wouldn’t have Seastone, but water was something that existed in every world.

“Although it seems like my Glint-Glint Fruit is somewhat special and may not have the same weaknesses as ordinary Devil Fruits, it’s still better to test it out first to avoid any unexpected surprises.”

With that in mind, Yu approached the lake.

The lake water couldn’t compare to seawater, but it was enough for testing purposes.

The small lake was crystal clear, so he didn’t need to worry about it being dirty.
Also, the water near the shore wasn’t deep.
In case of any accidents, Yu could immediately react and get back on land.

As a little boy of seven or eight years old, he naturally didn’t need to worry too much about embarrassing issues.
Moreover, there was nobody around in the pitch-black surroundings.
Yu quickly took off his clothes and cautiously entered the water.

“Hoo~”

The cool lake water instantly dissipated the fatigue and heat generated from his previous speed-of-light movement.
Yu couldn’t help but let out a satisfied breath while silently checking if anything felt out of place.

Several seconds passed…

Several minutes passed…

There was no feeling of weakness, fatigue, or discomfort in his body—only one word: refreshing!

Standing up and looking at his own body and hands, Yu’s face brimmed with delight.

“Great! Judging from this, the special and mysterious Glint-Glint Fruit that fused with my body doesn’t have any weaknesses like the Devil Fruits in One Piece.
That’s excellent!”

Feeling joyous, Yu thoroughly enjoyed playing in the water and even attempted to run at the speed of light on the surface and in the water.

Running on the water posed no problems at all.

In an instant, he could reach any point in a straight line, regardless of direction.

However, due to the nature of light, refraction occurred easily in the water.
This caused Yu’s movements at the speed of light in water to deviate slightly and be slower than in the air.

“Tsk… It seems that the characteristics of light are unavoidable during movement.
If I want to make smooth turns while moving at the speed of light, I can only rely on the Yata no Kagami,” Yu pondered, chin resting in his hand.
“If I can freely turn while moving at the speed of light, ah, right! I still have the Digitized Genes! As long as I merge with mysterious substances containing special powers, I can strengthen my abilities.
Maybe I can break through the unique properties of light!”

With this in mind, Yu called out in his heart.

“Flash, my ability to move at the speed of light, can it be strengthened to the point of breaking the straight propagation nature of light, allowing me to make turns at will?”

“Flash” was the code name he gave to his Digitized Gene Persona.

He found that his Digitized Gene was similar to the Speed Force Barry Allen, the Flash.
In essence, the Speed Force was also a dimensional space, operating like an intelligent system, and assuming various familiar forms based on the subconscious.

Therefore, Yu gave his Digitized Gene a code name—Flash.

However, unlike the Speed Force, Flash could appear anytime, anywhere, and communicate with Yu.

Soon, Yu felt the sky brighten, and Flash appeared in front of him, transforming into his own likeness and nodding.

“In theory, strengthening will make specific modifications to your abilities based on your desire for power.
Since you hope to break the straight propagation nature of light, as long as there is enough mysterious substance power, you can master this ability.”

“I see…”

Yu nodded, understanding it.

If that’s the case, apart from training, he should now search for the mysterious substances containing special powers that Flash mentioned.

However, substances containing special powers…

The first thing that came to Yu’s mind in the Marvel world was, of course, the famous Infinity Stones.
But how could he find the Infinity Stones now? Moreover, even if he found them, with treasures like these, many people would covet them.
How could he obtain them in his current situation?

“It’s a bit of a headache.
In the Marvel world, besides the Infinity Stones, there should be other things that meet the requirements, right?”

As Yu was thinking, a strange expression appeared on his face.

Because Flash alerted him:

“There is a presence of mysterious substances containing special powers within a radius of three hundred meters!”
