Chapter 723: Jin Jiu Arrives

Cough!
Clang! clang!
Inside the icy cave filled with biting wind, Kai Xin and the Silver Blade Protector quickly exchanged positions. Blades and swords flashed in the air, but neither was injured.
Although the Silver Blade Protector was surprised that Kai Xin could still fight, the brief exchange only confirmed his suspicion—that Kai Xin’s vital energy was unable to function properly, and his cultivation level had dropped to the life-and-death stage. He was relying solely on quick movements and the sharpness of his divine weapon to deflect the opponent’s attacks skillfully.
“Hmph!”
Though amazed and inwardly admiring the Murong family for having such a talented person, the Silver Blade Protector increasingly felt the relentless cold of the icy cave taking a toll on him. With a cold snort, he attacked again.
This time, Kai Xin managed to dodge safely.
Although it still took some time for his vital energy to recover, the innate advantages granted by his mastery of the Nine Yang Divine Skill, along with his agility and extensive combat experience, made it not difficult for him to defend himself—the Silver Blade Protector’s strength had diminished significantly. Now, he was at most a top expert at the ordinary Wu Wei realm.
Ignoring the extreme cold, Kai Xin used the Little Elixir to accelerate the recovery of his internal energy while closely monitoring every move of the Silver Blade Protector to anticipate and counter them.
“Seeking death!”
The Silver Blade Protector’s forehead furrowed deeper, and his movements grew faster.
Kai Xin wanted to recover quickly, but the previous attack had caused severe disruption to his internal organs. Moreover, the Silver Light Arhat technique consumed a tremendous amount of internal energy, making it difficult to recover in a short time…
With no other choice, he continued to engage the Silver Blade Protector in the icy cave, searching for weaknesses in his slowing attacks and using speed to counter his opponent’s slowness, preventing him from fully unleashing his power.
Half a minute passed.
They had exchanged over a hundred blows.
As usual, due to the failure of both his protective measures and equipment, Kai Xin had to focus entirely on dealing with the Silver Blade Protector, being extremely cautious and not daring to make a mistake. He was fully immersed in the battle…
Dodging, moving, shifting positions, drawing his sword, thrusting, spinning strikes, diagonal slashes—all simple moves without any internal energy. He relied purely on his strength and agility to outmaneuver the Silver Blade Protector.
Despite the pressure, Kai Xin was unaware that his opponent was already shaken mentally, realizing that the initiative was slipping away and now in Kai Xin’s hands. He didn’t notice any of this at all.

Kai Xin knew only that he must seize the sole advantage of the Silver Blade Guardian’s reduced attack speed—launching continuous attacks to prevent the Guardian from fully unleashing its destructive power and threat, thereby buying more time to restore his internal energy and the flow of his true energy.
As time passed…
Kai Xin didn’t even realize it. With a firm goal in mind, his swordsmanship became more vibrant, faster, and more proactive. Each strike targeted the Guardian’s most vulnerable points, combining the preemptive tactics of the “Yi Sword Art” to strike first, restrict the enemy, and disrupt their formation.
A few minutes passed.
Kai Xin didn’t even know how many times he had swung his sword, nor did he realize that his speed was gradually increasing without him noticing.
Soon!
Ding!
A system notification sounded in his ears:
“Congratulations! Your mastery of the ‘Heavenly Sky Thunder Annihilation Style’ has advanced to the fifth level…”
Fighting against a powerhouse at the Mythical Realm, especially under such special circumstances, finally stimulated Kai Xin’s potential, allowing him to make significant progress in a short time.
In the realm of Liberation Arts, advancing one level in the early stages is equivalent to advancing two levels in the Life and Death Realm. This unexpected system notification delighted Kai Xin greatly.
But he quickly focused again and continued to strike…
His main purpose for coming to the Heavenly Demon Cave was to practice swordsmanship. However, using a master at the peak of the Non-Action Realm as a sparring partner was certainly not as effective as fighting against a Mythical Realm powerhouse. Such a rare opportunity…
He couldn’t afford to miss it.
Now that his internal energy had been restored, Kai Xin seemed to have discovered a faster way to train. Instead of channeling his energy throughout his body, he continued to fight the Silver Blade Guardian in his previous state.
Now, the Silver Blade Guardian was already trapped in a stalemate with him…
In the extreme cold environment of the Ice Cavern, it was impossible to retreat unscathed from the battle. Moreover, the Silver Blade Guardian, being proud by nature, could never tolerate being defeated in a one-on-one duel by a junior.
Despite his pale lips, the Guardian gritted his teeth tightly, his silver blade flashing dazzlingly as it clashed with the sword strikes that resembled fine electricity.
Normally, those swift swords posed no threat to him at all—he could cut them in one strike. But the opponent’s divine weapon was not only of superior quality but also seemed to have been specially forged, reaching a level comparable to his own silver blade. And…

Happy was extremely cunning. Since his sword strikes lacked internal energy, he never gave his opponent a chance to engage head-on. Instead, he always used his agile movements to adopt a strategy of bypassing the enemy’s defenses to rescue his own forces. He tried several times to regain the initiative but lost it quickly, falling back into the opponent’s rhythm once again. Gradually, the Silver Blade Guardian realized with frustration that the opponent’s sword strikes were getting faster and faster. The opponent, with his upper body bare, showed no fear of the extreme cold in the cave, and seemed to have endless energy. The battle grew more intense by the moment… It no longer seemed like a struggle to defend oneself; the opponent seemed to be thoroughly enjoying the fight. When the Silver Blade Guardian occasionally showed a weakness and urgently activated his protective barriers, the opponent didn’t even glance his way and continued as before. Just a sparring partner… The Silver Blade Guardian was so angry that his beard trembled. A powerful being at the Mythical Realm level was being treated as a sparring partner by a junior disciple from a noble family. Finally, the Silver Blade Guardian thought about leaving. It wasn’t out of shame at being treated as a sparring partner, but because the cold poison was continuously eroding his body, slowing him down and making it harder for him to move. Even his weapon felt like it no longer belonged to him, turning into a bone-chilling ice blade. He feared that if he didn’t leave now, delaying any longer would mean it would be too late to go… Just then, a faint shout came from outside: “…Where are you!!” Hearing this voice, the already anxious Silver Blade Guardian felt as if he had been injected with a boost of strength. Energy surged back into his body, and he became much more energetic! His silver blade emitted an astonishing blade light, shattering the sword light in front of it and hitting the ice wall with a loud crash. “…” Happy’s expression changed! The Golden Blade Guardian, sensing that things were going wrong, had rushed over. There was no time to delay any longer! Almost simultaneously with the Silver Blade Guardian using this method to signal the Golden Blade Guardian’s location, the internal energy of the Nine Yang Divine Skill spread throughout his body. With a shake of his wrist, streaks of lightning-like blade light intertwined in the air at an even faster and sharper pace. In an instant, the cave was filled with the continuous sound of sword energy.
