Steel Bone Kong was not a Devil Fruit user, so even when he fell into the sea, it was no issue for him, though he was not particularly accustomed to water combat.
"Life Return: Swimming Form!"
Seeing this, Li Yuan immediately plunged into the sea as well, using Life Return to alter his breathing form. Over the years, he had continuously refined this swimming form with Life Return to integrate into the ocean like a Fish-Man, swimming freely and effortlessly.
Now, even if he exerted himself fully in the sea, he could maintain this form for three hours. This ability significantly enhanced his combat capabilities in sea battles.
"Life Return: Limb Liberation!"
Simultaneously, Li Yuan quickly released the extreme limb strengthening state, reverting to a normal strengthened limb state. The extreme state was something he dared not sustain for long due to its severe side effects.
Upon entering the sea, Li Yuan let go of the Infinite Sword Intent and switched to Abyssal Intent. In the ocean, Abyssal Intent could receive the greatest enhancement.
With Abyssal Intent, Li Yuan could manipulate the ocean's water to augment his attacks, just like a mermaid.
"Li Yuan!"
Seeing Li Yuan charging at him, Steel Bone Kong angrily launched himself at Li Yuan across the sea, determined to capture him!
"Treading the Sea!"
Once in the ocean, Steel Bone Kong's speed slowed, but Li Yuan's increased, negating his previous speed disadvantage. Abyssal Intent allowed Li Yuan to hear the rhythm of the sea, easily channeling the ocean's power into his sword.
"Abyssal: Water Dragon's Roar!"
With a single slash, a 500-meter blue strike roared like a dragon, bolstered by the surging waves. In front of this dragon, Steel Bone Kong seemed diminutive.
"Bone Fist: Starfish!"
No matter what sword technique Li Yuan used, Steel Bone Kong countered with a simple punch. Against his top-tier Armament Haki, any attack seemed powerless.
Li Yuan was aware of the gap between him and Steel Bone Kong, so he wasn't surprised when his slash was shattered. If Steel Bone Kong couldn't even do this much, Li Yuan would question his strength as a Navy Admiral.
With the Water Dragon's Roar shattered, Steel Bone Kong's body was once again forced to sink several hundred meters.
"He's trying to force me down!"
After several rounds with the same outcome, Steel Bone Kong realized Li Yuan's intention.
"Treading the Sea!!"
"Abyssal: Sea Tornado!!"
Li Yuan gave Steel Bone Kong no respite, using his swift aquatic movement as a core, with Abyssal Intent on the Seven Star Sword erupting again. The once calm ocean currents were stirred up, forming a massive underwater tornado.
Trapped in the sea tornado, Steel Bone Kong was pressured downward by the ocean's force. He felt incredibly stifled as Li Yuan continued his long-range strikes from afar, exploiting his slower speed in the ocean.
Li Yuan's tactics were frustratingly effective, a stark contrast to Rocks' head-on battles. Steel Bone Kong found himself unable to utilize his strength effectively. Furthermore, Steel Bone Kong could hold his breath underwater for up to an hour, but only if he didn't exert himself. In this situation, he could hardly last a quarter of that time.
"Indeed, my Mind-Reading Haki is useless against someone so much stronger."
"Their will is too strong; my Observation Haki can't read their thoughts."
During his battle with Steel Bone Kong, Li Yuan had frequently attempted to use mind-reading but never succeeded. Previously, he could occasionally read the thoughts of the stronger Golden Lion during combat. However, against Steel Bone Kong, his mind-reading failed, indicating that his Observation Haki had its limits.
As the battle in the ocean continued, Steel Bone Kong was pressed down to a depth of a thousand meters. Just when Li Yuan thought he could maintain the upper hand, Steel Bone Kong suddenly exploded with tremendous power.
Steel Bone Kong channeled Armament Haki into his legs, using it as propulsion to dramatically increase his speed in the water. This technique was one he'd rather not use due to its rapid consumption of Haki, which against an equal opponent would be a disadvantage.
But against Li Yuan, it was permissible. Steel Bone Kong didn't head to the surface for air but charged straight at Li Yuan!
Facing Steel Bone Kong's assault, Li Yuan dove deeper, with Steel Bone Kong in hot pursuit. Steel Bone Kong was confident that if he could get close to Li Yuan, he could capture him quickly!
At a depth of two thousand meters, Steel Bone Kong caught up with Li Yuan!
"Hmph, I'm not afraid of you!"
In this deep sea, Li Yuan felt confident enough to confront Steel Bone Kong. Abyssal Intent gathered a massive amount of seawater, compressing it into a colossal 500-meter-long water dragon.
"Abyssal: Sea Dragon's Roar!!"
With a slash of the Seven Star Sword, the compressed water dragon roared like a true sea dragon, rushing toward Steel Bone Kong to swallow him whole.
"Bone Fist: Impact!!"
Steel Bone Kong responded with a punch, his formidable Armament Haki unleashing a shockwave that shattered the entire water dragon.
Simultaneously, Steel Bone Kong surged closer, throwing a punch at Li Yuan's face.
"Clang!!!"
With Armament Haki covering the Seven Star Sword, Li Yuan blocked Steel Bone Kong's punch.
"Boom!!!"
However, under the powerful impact of Steel Bone Kong's Armament Haki, Li Yuan was sent flying hundreds of meters. Though the punch didn't land directly on Li Yuan, the shockwave caused him pain, his insides churning as he spat a mouthful of blood.
This highlighted Li Yuan's weaknesses: his Armament Haki and physique were too weak. He possessed Admiral-level attack power but couldn't withstand Admiral-level attacks.
Even so, Li Yuan remained unafraid. With the Sword God Tempering Technique in operation, he quickly suppressed his injuries, allowing for gradual recovery.
