The Strongest Assassin of the Zoldyck Family!

A large spherical object entered Ron's line of sight.

Silva lifted the cloth covering the sphere, revealing its true form.

It was a multicoloured egg.

Its colours constantly shifted.

Red, orange, yellow, green, blue, indigo, violet...

The red egg Ron had acquired earlier had only one constant hue: red.

"The primary function of the multicoloured egg is to enhance physical constitution," Silva explained. "It can be consumed raw or cooked. However, the effects diminish significantly after the first consumption."

Silva brought out two large containers.

He approached the multicoloured egg and lightly tapped it with his finger. A small opening appeared, and he tilted the egg, pouring its liquid contents into the containers.

One container was filled one-third of the way, while the other received two-thirds.

Ron had no complaints about this allocation.

Silva had handled most of the effort in defeating the old monk. Ron had merely distracted a portion of the Nen spirit's attention.

Receiving even a third of the multicoloured egg's liquid was already generous.

Just as Zeno had sold the Rotten Life Blade to Ron for 10 billion Jenny in the past.

"Drink it quickly for the best effect. If left for too long, its potency will decline."

"By the way," Silva added, "the result of the Nen spirit's sale has been finalized. The Underworld Mafia was interested and has taken over its location. In exchange, they paid us a sum of money: 20 billion Jenny and a monster. The monster is worth more than the money, so we'll split the 20 billion Jenny evenly."

Ron raised an eyebrow, surprised that the Nen spirit could fetch such a high price.

For the Zoldyck family, the Nen spirit held little value since the Ganlu Temple couldn't be relocated. The family had limited manpower and couldn't afford to station members there indefinitely.

However, for other forces, especially the Underworld Mafia, the situation was different.

With vast numbers and influence, they could easily assign personnel to control the Nen spirit and develop it into a new base of operations.

"Uncle Silva, transfer my 10 billion Jenny directly to Grandpa Zeno. I still owe him that amount."

"Alright."

Ron picked up his container without hesitation and poured the liquid into his mouth. Surprisingly, it lacked any strong odour or taste—almost like drinking water.

As it entered his stomach, Ron felt a warm sensation spreading from his abdomen to his limbs and throughout his entire body.

The feeling was similar to when he consumed the red egg, but this time, it was much more intense.

After all, this was a completely different entity. The multicoloured egg contained far more energy than the red egg and offered comprehensive benefits rather than focusing on just one aspect.

"Gulp, gulp!"

Soon, Ron finished the liquid in the container.

"It's getting late, Ron. You should head back."

"Alright."

The two parted ways. Ron returned to the Sky Arena, while Silva stayed near Killua, quietly protecting him.

---

A month passed.

Ron and Silva stood at the edge of a city.

Nina and Sally remained in the background, guarding Killua.

"Ren!"

"Ken!"

"Zetsu!"

"Ten!"

"Ko!"

For an entire month, Ron focused on training Ko.

Using a full-force approach, he significantly accelerated his progress.

Through high-intensity practice, even his muscles developed a memory for the techniques.

Back in his room, Ron would constantly analyze and reflect, further enhancing his skills.

His progress was rapid.

A large Nen bullet formed in Ron's hand. Under his control, it compressed and condensed until it was the size of a small ball.

Gritting his teeth, Ron pushed his limits.

Suddenly, as if breaking through a bottleneck, a crisp sound echoed.

Ron glanced at his right hand.

The aura condensed around his fist had undergone a transformation. It was no longer chaotic but had entered a relatively stable state.

"This feels similar to Naruto mastering the Rasengan!"

Looking at the Nen bullet in his hand, Ron turned his gaze forward.

"Go!"

The Nen bullet shot out, hitting a distant hill.

"Boom!"

A massive explosion followed.

The entire hill was obliterated, leaving a crater where it once stood.

Ignoring the destruction, Ron focused inward, recalling the sensation of using the Nen bullet and Ko.

"A 90% completion rate! I've reached it!"

A smile spread across Ron's face.

Since beginning his training in advanced Nen techniques, it had taken him nearly half a year to achieve a 90% mastery of Ko.

In truth, this was remarkably fast.

Even Silva regarded it as an impressive speed.

Previously, Ron's progress had been even smoother.

After developing "Essence of the Observer," he had quickly acquired Killer Queen, then Hanma Baki, all within a short period.

His Nen beasts, such as Chii, also required minimal effort.

The only significant delay came from the Fighting Tournament and navigating the Underworld Mafia's vast influence.

Despite these challenges, Ron had made other gains.

Now, he devoted all his energy to improving his core abilities:

- Physical training.

- Combat practice.

- Advanced Nen techniques.

His Nen beasts were temporarily on hold. Even Nina and Sally took a backseat as Ron focused on this singular goal.

"For my Nen rank, I hadn't increased in rank yet," Ron noted. "But my overall strength has increased significantly."

"Physical resilience has improved dramatically."

"My mastery of Ken, En, Ko, In, and Shu is at 90% completion."

"Additionally, I've enhanced my Nen bullet technique."

Although Ron could unleash a devastating Nen bullet by consuming all his aura, he deemed it too risky for regular combat. However, his ability to condense Nen bullets had improved significantly. A single bullet now packed a punch comparable to a rocket launcher.

"Finally, this stage of training can conclude."

"Next, it's time to gather the traits of the Taris Kingdom and create my fifth Nen beast."

Ron took out an email address.

It was one Zeno had given him earlier, belonging to a member of the Fiora royal family.

Ron briefly described his situation and sent the file to them.

"I wonder when they'll reply."
