Lord: Sequence Master

Rosen sat at the tea table, staring at the drawings laid out before him. Each one represented a potential Nen ability he had envisioned. He wanted them all, but Nen's abilities weren't about having as many as possible. He needed to find the one that suited him best—one that would be the most effective in his current situation.

To narrow it down, Rosen began eliminating options.

The first to go was a drawing of the Sharingan—a power he had longed for in his younger days. Back then, he had envied the Sharingan's ability to copy techniques, especially during exams. Developing a Nen ability to mimic the Sharingan wasn't impossible, but in reality, there were no ninjutsu techniques to copy—only the supernatural abilities of different extraordinary Sequences. While copying these powers was feasible, mastering them to the same level as their original users—who had honed them through countless trials—would be far more difficult. His current level of Nen wasn't sufficient for such perfection.

Rosen set the Sharingan drawing aside and picked up the second one, which depicted the mysterious study.

His idea was to create a Nen-based space identical to the mysterious study, merging the two realms and using his Nen ability to better control the study. This could, in turn, strengthen his own abilities. However, such an ability would lean heavily toward support and would take time to develop. What Rosen needed right now was offensive power, so he decided to set this idea aside for the moment.

The third drawing he picked up depicted a paintbrush, palette, paper, and easel.

This concept involved merging Nen with his artistic abilities, enhancing both his Nen and his Painter Sequence powers. He imagined being able to draw something like Pikachu and materialize it as a Nen beast.

"Still not quite right," Rosen muttered, setting the drawing down.

While this idea would amplify the power of both Sequences and potentially conceal his Hunter Sequence abilities, the Painter Sequence was naturally suited for working from the shadows. It didn't necessarily need such enhancements. More importantly, Rosen wanted an ability that could strengthen him in combat. After all, the biggest weakness of the Painter Sequence was the vulnerability of the artist himself.

Finally, Rosen was left with two remaining drawings—one in each hand—and hesitated.

In his left hand was a picture of a gun—an excellent choice for the Hunter Sequence, especially for ranged combat. A hunter without long-range attacks wasn't a true hunter. In his right hand was a bow, complete with various types of arrows.

Deciding between the gun and the bow was tough.

In this supernatural world, bows were not inferior to firearms. In fact, they could even be deadlier because arrows could be infused with more spiritual energy than bullets, which were too small to hold much power.

Of course, firearms had their advantages too, with faster firing rates and greater explosive force.

"Only children make choices. I'll take both," Rosen said with a grin.

He set both drawings aside and gathered up the others, having reached his final decision.

Rosen grabbed his pen and quickly sketched a highly unusual weapon. It had a long gun barrel but also a crossbow mechanism mounted on it.

The overall design resembled something like an ancient crossbow rifle, or a God-Slayer Crossbow, but more advanced. The weapon could fire both bullets and crossbow bolts, combining the advantages of both.

(Imagine it as a steampunk-style weapon with a metallic finish.)

Rosen added a scope, but instead of a typical one, it was a rotating eyeball. This eyeball would be linked to his vision, acting as a third eye. It could provide all the benefits of scope, and in the future, as his Nen ability improved, he envisioned it gaining various ocular powers.

Next, Rosen drew a detachable magazine. The magazine had a one-cubic-meter storage space, capable of holding a large amount of both bullets and crossbow bolts.

This served as a budget-friendly alternative to the mysterious study's space. For now, the magazine's internal space was limited to one cubic meter, but as his Hunter Sequence advanced, the magazine might grow into a small world of its own.

Rosen aimed to develop the seed of a spatial Nen ability, laying the groundwork for more powerful space-manipulating techniques in the future.

Lastly, he integrated his painter's tools—paintbrush, pigments, and paper—into the magazine. All bullets and crossbow bolts stored inside would need to be drawn by him. Since directly enhancing his Painter Sequence through the Hunter Sequence seemed difficult, Rosen decided to reverse the approach, using the Painter Sequence to enhance his Hunter Sequence.

Having finalized his Nen ability design, Rosen immediately began drawing it on spiritual paper, infusing the drawing with spiritual energy.

The strange crossbow-rifle hybrid emerged from the paper, but the eyeball scope still looked lifeless. Though the eyeball could rotate, it remained as dead as any regular object. With his current level in the Painter Sequence, Rosen could draw a steak, but not a living cow.

The eyeball was the same—functional, but not alive. Fortunately, it didn't need to be alive for him to begin developing his Nen ability.

Rosen channeled his spiritual Nen into the weapon, letting his aura seep into every part of it. He used his Nen to construct each component of the weapon, familiarizing himself with its intricate design.

Over time, his Nen gradually materialized and became solid under the influence of Conjuration-type abilities.

After five days of intense practice, Rosen was able to materialize the crossbow-rifle entirely through Nen, without relying on any physical object.

He continued enhancing the weapon by applying different types of Nen:

Enhancement: To strengthen the overall structure and durability of the weapon.

Emission: To increase the power and speed of the bullets and bolts.

Manipulation: To control the projectiles remotely after they were fired.

Conjuration: To make the bullets and bolts behave like living Nen beasts, capable of tracking and adjusting their path mid-flight.

 Specialization: To give the magazine spatial properties and the ability to toggle between physical and spiritual forms.

Finally, Rosen used his Specialization-type Nen to imbue the magazine with the ability to store spiritual energy. This allowed him to use his Painter Sequence abilities to create bullets and bolts within the magazine, and it gave the eyeball scope the potential to develop eye techniques in the future.

Normally, developing such a greedy and complex Nen ability would be impossible.

But Rosen had several advantages: spiritual energy to enhance his Nen, the extraordinary essence of the Hunter Sequence (which provided a natural affinity for weapons), and his Painter Sequence, which could manifest spiritual constructs.

With all these elements combined—and his 100% affinity across all Nen categories—Rosen had successfully conjured the ultimate crossbow-rifle hybrid, a weapon worthy of the title God-Slayer Crossbow.
