Yin Wu Lei, Both Hands

"Conquer Enel, prevent Birka from being destroyed, slightly alter the future world line, and reward Leifa!"

The system's voice announced: "It is detected that the Host is no longer a child. The thunder method has automatically transformed into [Water Dirty Thunder]!"

As soon as the system finished speaking, Arias felt the energy within him shift. The essence of his internal fluids began receiving energy from the liver and wood, allowing the yin energy to dominate. His strength increased, and as the yin energy was generated, the yang energy automatically replenished and refined it.

A stream of thick, black liquid manifested in the palm of his hand.

The Qi flowed downward, a characteristic of Yin Thunder that inherits the properties of water.

Reaching out, twisted Yin Thunder shot from his fingertips like earthworms, snaking forward as the surrounding temperature dropped slightly.

Yin Thunder could absorb heat.

Arias's expression changed as he summoned large white clouds, which quickly condensed into dark clouds. A substantial amount of thunder emerged from his body and entered the clouds, causing the temperature inside to plummet.

First, the clouds condensed into water droplets, which then transformed into hailstones.

Hailstones began to fall from the sky, causing the ground to crackle with each impact.

"It's a shame that hail is as indestructible as rain."

Arias noted that the impact of hail wasn't very useful. Instead of cooling the dark clouds and creating hail, wrapping the enemy in northern blue energy would be more effective.

Withdrawing the Yin Qi, he prepared another method for eliminating enemies.

He called out to Enel, "I have a mission for you."

Enel listened intently.

"Dominate Sky Island and become its absolute ruler!"

Enel's heart raced. This was his ambition, but his recent defeat and loss of heart had dampened his spirits. Now, receiving Arias's permission was a tremendous relief.

"Yes!"

Sky Island had unique materials, including shells with various functions. Having Enel in charge would also facilitate the collection of these materials, which could have unexpected magical effects when used in refining tools.

Having been away for a long time and with Hancock on Nine Snake Island urging him to return, Arias went back to the Birka island owner's mansion to bid farewell.

"Brother Arias, are you leaving?" Sterility asked, clearly reluctant and expressing a desire to accompany him to the next world.

"Good girl, Birka still needs you to rule. Your presence here is crucial. I'll return to visit you once I've taken care of my current matters."

After reassuring her, Arias noticed Delia stepping forward to speak but ultimately remaining silent.

He smiled and nodded at her. "Practice the techniques I've taught you. They will not only make you stronger but also keep you youthful and extend your life."

Drawing a talisman in the air, he used Babel to create a "sword-controlling talisman," mounted his spiritual sword, and dove into the sea of clouds, heading straight to the lower realm.

With this method, travel became much more convenient and significantly faster than using a ship.

After several changes of spiritual swords during his journey, he returned to Nine Snakes Island, checked on Zoro and others' progress, and then spent time with the Hancock sisters in Nine Snakes City.

The next day, Luo Lin, who had opened a café in Sabaody, sent treasure materials from Mariejois. Arias entered the refining room again to start a new round of refining.

At the very least, he needed to upgrade the weapons of his key confidants to the level of supreme sharp knives.

The current sea was in chaos. Dragon had led the top cadres of the Revolutionary Army to attack Enies Lobby before quickly retreating. However, Tai Neng had not continued to deal with the Revolutionary Army's slaves to protect Ginny, resulting in many revolutionary soldiers being rearrested.

Due to Big Bear's failure to secure the area, many revolutionary soldiers were attempting to escape to the Holy Land.

The top leaders of the Revolutionary Army clashed with the Knights of God in a fierce battle. Dragon and Crow were seriously injured and fled, while Ivankov was captured.

As a result, Dragon and Big Bear had a falling out, with Dragon severely reprimanding Big Bear and losing much trust in him.

The Marine branch in Shihai was heavily damaged. Although Akainu and others arrived to support, the Revolutionary Army had already retreated by the time they arrived.

At Impel Down, the Whitebeard Pirates had forcefully breached the gates. Director Magellan was killed in the battle, but their leader Shiryu was seriously injured and escaped. Many jailers and others were killed or injured, and all prisoners, including Katrin Dieme, San Juan Wolf, Basque Choate, Abarro Pizarro, Baloric Redfield, Byrnndi Waldo, and Douglas Bullet, were released.

With the arrival of the Whitebeard Pirates, these once-notorious pirates had returned to the seas.

The Golden Lion Shiki, once as famous as Roger and Whitebeard, had devastated Marineford, destroyed most of the base, and escaped despite losing a left arm. Shiki now had both legs and his left arm broken, leaving only one arm intact.

Arias reviewed the newspaper reports. Although the details differed somewhat from the actual events, his numerous intelligence channels had provided him with the full picture.

"Tsk, tsk, this will certainly boost the confidence of those seeking treasure."

"Enies Lobby destroyed, Impel Down breached, and Marineford severely damaged. The World Government and Marine's prestige have reached an all-time low."

"Especially with the reappearance of those once-feared pirates, the seas will be even more chaotic!"

"Such significant changes were caused by my actions, so I expect a substantial reward!"

He eagerly anticipated the system's reward.

Sure enough, the system's voice resonated in his mind:

"Due to your actions causing widespread chaos and targeting the Revolutionary Army in advance, the world line 553 has been significantly altered. You are rewarded with one of the eight magical skills: [Double Hands]!"

Arias's eyes brightened. He had received the [Double Hands] skill!

Currently, only two magical skills remained: Fenghou Qimen and Daluo Dongguan.

While Daluo Dongguan was not immediately important, acquiring Fenghou Qimen would enable him to start building a self-cultivation furnace, allowing for the mass replication of ability users.

Even with just two hands, he could accomplish much.

Before taking further action, news arrived from Solomon's intelligence network that Nico Robin was hiding in a branch of the World Economic News Agency in West Blue, controlled by Morgans.

Solomon inquired if he should retrieve Robin.

After some consideration, Arias declined the offer. Robin, having lived in betrayal for the past twenty years, would be highly cautious and could flee at the slightest disturbance.

He instructed Solomon to ensure Morgans did not alert Robin and decided to send a puppet to retrieve her.

In the New World, Arias controlled the puppet and sailed west across the Calm Belt to West Blue.

In a West Blue newspaper office, a beautiful lady with a slim figure and distinctive features pushed open the office door with a document in hand.

"Lori, you did a great job! Would you like me to recommend you to the headquarters?"
