The Frostweeping Blade is a Heaven and Earth Rare Treasure born within the territory of Heavenly Vault Pass ten years ago.
However, this Heaven and Earth Rare Treasure was not yet fully formed; it was still a work in progress.
At the time, Li Zhao was seriously injured and had a strange corrosive power within his body. In the end, the only option was to take the Frostweeping Blade to suppress the corrosive power within Li Zhao's body.
Over the years, the Frostweeping Blade has also been tainted by the power of corrosion.
This time, Li Xiyun broke through to the King Realm, so she risked her life to attract the King Realm's Sin Beast.
The surrounding King Realm Sin Beast, the Heavenly Vault Army, were already aware of this, and it was highly likely that the ones coming were the Heavenfall Dragon King and the Bone War Chief.
Especially the Bone War Chief, whose Frostweeping Blade's corrosive power perfectly countered the opponent's Indestructibility Rule.
The power of erosion alone would not be enough to defeat the Bone War Chief, but when combined with the Extreme Cold Rule of the Frostweeping Blade, it has achieved its current effect.
puff...
At that moment, Li Zhao spat out a mouthful of blood, his face turned even paler, and his aura weakened.
For so many years, the Frostweeping Blade had helped suppress the corrosive power within him. Now that the Frostweeping Blade was gone, the corrosive power within him surged once more.
"Young Master, quickly take this pill."
An old man beside Li Zhao hurriedly took out a pill and fed it to the other person.
The Nirvana Life-Extending Pill is a top-tier Mythic Rank elixir; even those on the verge of death can be instantly healed after consuming it.
Originally, the Nirvana Life-Extending Pill was King Rank pill, which required the ashes of a phoenix that failed to undergo Nirvana, Dragon Blood Crystal formed from the blood of a true dragon's heart, and a large amount of rare and precious materials to be refined.
Legend has it that the King Rank Nirvana Life-Extending Pill, once ingested, can not only instantly heal injuries but also allow one to be reborn, reshaping one's constitution and offering numerous benefits.
But putting aside the fact that these treasures are not so easy to find, even if they were found, only King Rank alchemist could refine them.
In the entire Heavenly Revelation Empire, there was only one King Rank alchemist, who was from the royal family, so naturally he couldn't offer any assistance.
After Li Zhao took the Nirvana Life-Extending Pill, his complexion improved slightly, but his aura remained largely unchanged.
The effects of the Nirvana Life-Extending Pill can only slow down the rate of erosion, and this condition can only last for a maximum of seven days.
Li Zhao didn't care about his own situation; after so many years, he had long been prepared to die.
Besides, now that my little sister has grown up, even if he were to die now, he would have no regrets.
"It's time for my little sister to make her move."
Li Zhao looked at Li Xiyun in the vortex and thought to himself.
Their scheme is only now truly beginning.
At the very moment the Bone War Chief was frozen, Li Xiyun, who was sitting cross-legged in the void vortex, suddenly opened her eyes.
Swish!
As Li Xiyun raised her hand, the frozen Bone War Chief vanished into the void.
When he reappeared, he was already standing in front of her.
Buzzing...
The next instant, the Frostweeping Blade embedded in the Bone War Chief's bones glowed faintly, and at the same time, the dense rules of heaven and earth around Li Xiyun surged and covered the Bone War Chief.
The Frostweeping Blade was originally a treasure she had refined, but over the years she had kept it on Li Zhao to help Li Zhao suppress the corrosive power.
Right now, Li Xiyun is going to use the rich rules of heaven and earth that she attracted during her breakthrough to help the Frostweeping Blade refine the Bone War Chief with its corrosive power, complete the incomplete rules of the Frostweeping Blade, and transform it into a true Heaven and Earth Rare Treasure.
Using the power fed back to her after her advancement with the Frostweeping Blade, she broke through to the King Realm.
"It seems our plan is going to succeed." Li Zhao couldn't help but smile as he watched this scene.
Thinking about it, he looked towards the direction of the void battlefield. After his younger sister broke through, she could join forces with his father to directly kill the Annihilation Sword Baron and the Heavenfall Dragon King.
Everything is proceeding according to their plan.
Lin An was naturally unaware of these plans.
He had already entered the battlefield.
Without the Bone War Chief, the oppressive feeling emanating from the remaining Sin Beast was much less.
Moreover, Lin An would not actively seek out Mythic Realm Sin Beast to fight; he would instead kill those below the Sin Beast Mythic Realm, killing a whole group with a single strike.
"It seems that my maternal grandfather, my eldest uncle, and my mother had planned this all along."
Lin An noticed the disappearance of the frozen Bone War Chief and already had a guess in his mind.
But whatever the plan, it's not something he can get involved in right now.
All he can do is take this opportunity to hunt down the Sin Beast and try to gain a lot of event points.
That's about enough.
Lin An One Saber Slash again, and seeing that the battle had reached a stalemate, he immediately had an idea, and 108 array flags flew out.
With Zheng Tang protecting him, no Sin Beast could disturb Lin An's formation.
" Wuji Wind Fiend Destruction Grand Formation, activate!"
With a soft shout from Lin An, all the array flags soared into the air with a whooshing sound.
The battle flags spun rapidly in the air, their array patterns gleaming.
In just a few minutes, these flags were quickly arranged into a huge formation.
The moment the formation was completed, a black tornado of wind appeared.
Boom boom boom...
Wherever the wind tornado passed, space seemed to be torn apart, emitting a series of ear-piercing roars.
The blood-red-eyed Sin Beast, sensing the threat, did not flee but instead charged forward.
Lin An smiled as he watched this scene.
He had seen the Green-Eyed Black Eagle use a White Bone Horn back in the Daling Great Ridge Mountain, the Third Line of Defense of defense at Heavenly Vault Pass.
This caused all the Sin Beast in Great Ridge Mountain to go into a frenzy, knowing only how to kill.
"As expected of a war horn created by the King Realm expert, its effect is far superior to the White Bone Horn we encountered before. Even Legendary Realm Sin Beast cannot be immune to this effect," Lin An thought to himself.
In comparison, the Sin Beast in the Mythic Realm are somewhat rational, though not many; they still know to run when things go wrong.
With the activation of the Wuji Wind Fiend Destruction Grand Formation, Lin An began his frenzied slaughter of the Sin Beast.
Wherever the Wind Tornado passed, all the Sin Beast were instantly annihilated. Even one or two Mythic Realm Sin Beast rushed over to try to save them, but were also swallowed up by the Wind Tornado.
The deaths of numerous Sin Beast caused Lin An's activity points to rise rapidly. As time slowly passed, his activity points quickly reached fifty million and continued to rise.
"Unless several Late Mythic Realm Sin Beast join forces or King Realm expert intervenes, breaking my formation is virtually impossible."
The King Realm Sin Beast are in the Void Battlefield, and the Sin Beast in the Late Mythic Realm are also a key target of the Heavenly Vault Army, so naturally they cannot be allowed to leave.
Even if they really come, Lin An has Zheng Tang by his side, and he has various powerful methods, so surviving is still a piece of cake.
Three hours passed quickly.
Click, click...
A cracking sound rang out from the array flags, and Lin An noticed that these flags had developed cracks.
Lin An was not surprised to see this, after all, it was something he had crudely created, and it was only thanks to the support of the Heart of Auxiliary Cultivation that it could last for at least an hour, let alone three hours.
"Then complete your final mission."
With a thought, Lin An caused the array patterns on all the array flags to flash with dazzling light.
Boom...
The next instant, a terrifying force erupted, and all the array flags self-destructed.
