Marvel: Starting with the Glint-Glint Fruit.

One reason for this is that his own mastery of Armament Haki is not yet sufficient.

Conqueror's Haki can impact the soul and spirit of demons, but its most destructive effect comes from the Glint-Glint Fruit.

To some extent, the Glint-Glint Fruit possesses some of the characteristics of light, which are effective against demons. Combined with the powerful and highly concentrated energy explosion, it gives him the foundation to hunt demons.

To put it bluntly, Matthew's stats aren't good enough. His Armament Haki and Conqueror's Haki aren't at the Admiral level, let alone the level of Garp, Roger, or Whitebeard.

In his current state, even with the enhancement of Armament Haki, it would be difficult for him to kill a demon directly with ordinary physical attacks, but the Glint-Glint Fruit could.

Once the required values ​​are reached, even a demon can be destroyed with a single punch if Armament Haki reaches a certain level.

I still need to cultivate myself.

Hunting demons won't interfere with his training. Besides materializing Devil Fruits, combat is also a form of training for Matthew.

The path to growth is never a monotonous process of training or simply crushing weaker opponents; it also involves intense, brutal, and even desperate battles where one must fight back against seemingly insurmountable odds.

Battles act as a catalyst, fully unleashing the power accumulated during regular training, allowing one to grow stronger in combat.

It can only be described as killing two birds with one stone.

"BOSS?"

While Matthew was thinking, he heard Negley's voice. Matthew glanced over and saw Negley driving attentively in the driver's seat.

"uh-huh?"

"Thank you," Nigley said abruptly.

"What are you thanking me for?"

"Thank you for leading me onto a more wonderful path," Nigley said earnestly without turning his head.

Matthew smiled but did not answer.

Nigley continued, seemingly oblivious to his surroundings: "Since retiring, I've been lost for a long time. I didn't know what to do. I tried many jobs to fill that void, but I failed."

"But you made me rediscover that fighting spirit I once had."

"It even led me down a different path."

Negri's voice was calm, but beneath that calmness lay an intense passion.

She joined the army not only because of her family background, but also because she was not a content person. She possessed an adventurous spirit that ordinary people did not have, and she was unwilling to be ordinary.

She originally thought that the 101 Special Investigation Team was her home, but after retiring, she fell into confusion again.

This is evident from the fact that she has never married or even found a lover.

Deep down, she still longed to step into the "battlefield" again.

Matthew gave her another chance, and even opened up a path that was more colorful and exciting than before.

Hydra, super soldiers, demons, hell—things she had never even imagined before—appeared one by one.

Furthermore, Matthew also granted her the power of the Memory Fruit.

Negri has always been a smart man. There are no fools among the members of the Special Investigations Unit. The fact that Matthew gave her this ability shows that Matthew trusts her.

She likes and enjoys the feeling of being needed, trusted and valued.

Most importantly, Matthew's work style suited Negri's taste perfectly.

So, the only reward Nigley could offer was loyalty!

"It's still early, Negley."

Even without Observation Haki, Matthew could sense the burning passion in the woman beside him. Why would he give something like the Memory Fruit to Negri?

It was because he understood Negri's personality.

As long as she is given trust and what she needs, she is Matthew’s loyal warrior, and that is absolutely true.

There are far too many people like Negley.

Matthew is a cautious person with a very high desire for control. Unlike Nick Fury, who trusts no one, he has unique self-confidence in addition to his Observation Haki.

Observation Haki allows one to perceive other people's emotions.

Humans are creatures adept at disguise, but under the influence of Observation Haki, the truest emotions cannot escape his perception. Even demons, creatures that are cunning and adept at disguise, cannot escape his Observation Haki perception, let alone humans.

During his time with Negley, he was able to clearly perceive Negley's emotional changes.

Aside from that, his confidence always comes from himself. He is not afraid of betrayal, for the supreme law of this universe is power.

Therefore, he is not stingy; on the contrary, he is very generous.

"Cool~~ I'm really afraid of falling in love with you, BOSS." Negri whistled, and transformed back into that dashing and capable girl.

"I'm still a minor, don't go down the path of crime, Negley."

Matthew jokingly retorted.

"Ha, crime!!"

Negri laughed and emphasized the word "crime," as if to say what we had been doing before.

"Where should I look for you next?"

"Margrave." Matthew's gaze turned to the window again, the scenery along the road flashing by.

He should go home.

............

On one floor of a three-winged building in Washington, D.C., a bald Black man wearing a turtleneck sweater and an eye patch listens silently as he sips coffee through a one-way glass window.

Inside was a somewhat timid girl wearing glasses.

On his temples and forehead were patches with connecting wires. Opposite him were several agents and analysts who were asking questions while monitoring the data on the equipment.

He stared intently at the girl with his one eye for a long while before turning and leaving.

Walking down the corridor, you arrive at a spacious hall with a polished marble floor, clean walls, and modern interior design.

I walked to the floor-to-ceiling windows in the lobby and gazed at the city shrouded in a layer of pure white. I seemed to be admiring the scenery, but my thoughts had already wandered off to another place.

Just then, I heard footsteps.

"The coffee's getting cold, Nick."

"What brings you to headquarters today, Pierce?"

Nick turned his head and saw Pierce, dressed in a suit, standing in front of him, also holding a steaming cup of coffee.

Pierce is the former director of S.H.I.E.L.D. and the current secretary-general of the World Security Council. He is responsible for liaising with Nick Fury, who is the current director, and S.H.I.E.L.D., but he rarely comes to headquarters unless there is a major mission.

Considering recent events, Nick Fury already had a guess in mind.

Sure enough, Pierce stated his purpose directly: "Devil's Jar".

"This is no small matter, Nick."

"It's really a headache." Facing his former boss and friend Pierce, Nick Fury didn't try to hide the matter.

The devil, Matthew.

Putting the latter aside, at least he is a human whose past can be traced and whose background is clean. But what Jennifer did in the Devil's Jar is the main reason that is really giving him a headache.
