Marvel: Starting with the Glint-Glint Fruit.

He accumulated check-ins two months ago, and the reward he received was the Six-Style Cultivation Method.

Now that two months had passed, Matthew thought for a moment and activated the rewards again.

"Ding! The 60-day cumulative sign-in reward has been activated. Congratulations on obtaining the Devil Fruit illustration."

As the cold, metallic sound rang in his ears, Matthew frowned slightly. "Devil Fruit Encyclopedia?"

Is this a complete tie to the One Piece world?

After silently grumbling to myself, I turned my attention to the new sign-in rewards.

[Devil Fruit Encyclopedia: Records 141 types of Devil Fruits, including Logia, Zoan, and Paramecia types. Devil Fruits can be created by absorbing the souls of demons (Note: The more powerful the Devil Fruit, the higher the quality of the demon soul required)]

Matthew paused for a moment after looking at the information in the Devil Fruit encyclopedia, then fell into deep thought.

This thing is much better than he imagined. After all, being able to create something out of thin air that doesn't belong to this universe is already quite impressive.

Many of these powerful Devil Fruits grant corresponding abilities upon consumption, including those with astonishing destructive power or those based on rules.

The price to obtain it is the soul of a demon, which fits quite well with the idea that Devil Fruits contain the will of a demon, and is very reasonable.

To put it simply, if he wants to obtain a Devil Fruit, he has to actively hunt down demons so that the Devil Fruit Encyclopedia can absorb his soul in exchange for the Devil Fruit.

While powerful Devil Fruits are certainly impressive, they cannot make someone truly defy the heavens.

For example, does his Glint-Glint Fruit really allow him to travel at the speed of light?

For example, could the Rumble-Rumble Fruit allow for the development of electromagnetic manipulation, or even extend to the spectral level?

Not necessarily.

This is not simply a matter of whether or not one has enough knowledge to develop and transform Devil Fruit abilities.

More importantly, it's about mastering the Devil Fruit's abilities. Even with enough knowledge, he couldn't possibly develop the Glint-Glint Fruit to an incredible level. The reason is simple: computing power is required.

Without sufficient computational power, the brain cannot support the development of other extensions using the Glint-Glint Fruit.

During this time, he also studied the theory of light and tried to combine theories of light polarization, electromagnetic interference, and quantum properties in his experiments while developing the power of the Glint-Glint Fruit.

But upon trying it, he immediately discovered that his brain's computing power was simply insufficient to support such an operation.

This is quite similar to the concept of a certain scientific railgun, combining development capabilities with computing power to achieve a certain level of precision in utilizing those capabilities.

The brain needs sufficient computing power to convert and utilize those abilities.

Unless the brain has a supercomputer to help with the calculations.

Otherwise, many Devil Fruits, despite their seemingly huge potential, actually have limited limits.

However, Matthew was not disappointed. After all, the possibility of development was there. As his life level gradually increased, his brain's thinking and computing abilities would also improve. Perhaps the sign-in system could bring him even more surprises.

Speaking of Devil Fruits, Matthew is quite interested. After all, the sign-in system rewarded him with the power of the Glint-Glint Fruit, rather than him eating a Devil Fruit. So, could he just eat a second Devil Fruit?

There are quite a few powerful Devil Fruits, such as the Gum-Gum Fruit in its final form (Nikka form), the Door-Door Fruit (a space-time type), the Op-Op Fruit (a powerful functional type), the Fish-Fish Fruit in its Azure Dragon form, the Tremor-Tremor Fruit, and so on.

Logically, he felt he should be able to.

Because the Devil Fruit encyclopedia includes the Glint-Glint Fruit, which belongs to the Logia type.

Whether or not to eat a second Devil Fruit is another matter.

The appearance of the Devil Fruit Encyclopedia greatly improved the feasibility of Matthew's original plan.

He wants to build his own team, or force.

He was not an ascetic in essence, nor was he a reclusive person. Rather than the lonely path of becoming a god alone, he preferred to change the fate of some people in the process of becoming stronger.

Of course, this is all predicated on his will.

The only problem now is that we need the soul of a demon.

Where can I find this thing?

This universe has the concept of hell, and demons exist in the hell dimension. Hell is a plane composed of countless dimensions.

Powerful demons who hold authority over these dimensions are called demon lords, and each demon lord is incredibly powerful.

Although there are differences in strength, they belong to the same echelon as the Heavenly Father.

Earth is a very special planet. Human civilization is considered a low-level civilization in the universe, but due to the special nature of the human race and Earth.

Demons love to descend upon Earth, feeding on human flesh and souls, manipulating humanity, emotions, and souls.

However, due to the differences between dimensions and the presence of a secret alliance of mages protecting Earth, demons dare not easily set foot on Earth. Otherwise, if they are discovered by the mages, they will either be banished back to Hell if they are lucky, or killed if they are unlucky.

Despite knowing the danger, the demons still flock to Earth, using mediums and channels to create fear and achieve their goals.

They might as well just smuggle themselves in, driven by greed and fearlessness.

However, finding and hunting these demons was no easy task. Matthew's eyes flickered, and just as he was deep in thought, a series of ringing sounds suddenly broke his thoughts.

He casually pulled out his phone and answered the call; Nigley's voice came from the other end.

"Boss, Rai Che is in trouble."

...........

Inside the closed solitary confinement room, the metal walls showed signs of age and decay, while the long tubular chandelier on the ceiling illuminated the room brightly.

Inside, there was only a simple rectangular metal table and two chairs.

Rachel, a big guy, sat in a chair wearing a black sweater, a brown coat, and jeans. His hands and feet were shackled, and his face had some wounds, bloodstains, and dust, indicating that he had been in a fight.

He remained calm and composed, seemingly unafraid of what was to come.

At that moment, with a sound, the metal door of the sealed room was pushed open, and three figures walked in. The one in the middle, who was the leader, was wearing a black combat uniform, had some stubble, a short blond haircut, and a gray scarf around his neck. The two on the other side were dressed similarly, and they all had a very sharp and capable demeanor.

"Raycher Jack, 38 years old, graduated from West Point Military Academy. He is proficient in all kinds of weapons, close combat, forensic medicine and criminal identification. He was transferred to the army as a military policeman and received rigorous training. He spent a total of thirteen years in the army, from general duties and security to being in charge of homicide investigations."

"He retired at the age of 36 with the rank of major. After retiring, he wandered around without a fixed place to live. He was used to hanging out in museums and bars, liked blues music, and traveled by bus and train, staying in cheap hotels."

"Without any identification documents or driver's license, and without an address, phone number, or mobile phone, and without credit cards, transactions are always conducted in cash, leaving no records and thus no one can trace them."
