Xiao Fei discovered that Xiao Lan was close to advancing to the Integration stage, so he immediately moved her dormant cave dwelling to the outside.
Another two days passed. Suddenly, a ghost mist emerged from the cave dwelling refined by Soul Nurturing Wood, spreading outwards and quickly engulfing the entire deserted island.
The sudden appearance of the ghost mist truly terrified the other cultivators hidden on the island, making their legs tremble and their desire to flee almost overwhelming.
Xiao Fei sent out a sound transmission to appease them, which managed to stabilize their emotions.
Following this, a large number of blood threads appeared within the ghost mist, spreading throughout all areas covered by the mist.
Gradually, these blood threads and the ghost mist began to converge, coalescing together, and the figure of a graceful woman emerged.
"Second Sister! You've finally awakened."
"Little Brother!"
After many years apart, the two finally met again, and naturally, they had much to discuss. They chattered away for a long time.
When Xiao Lan learned that Xing Wuming was also trapped in the valley by the undead, she immediately wanted to go to his rescue.
"Second Sister, the undead have dispatched dozens of Integration stage powerhouses this time, and they have also set up a powerful formation on the mountains surrounding the valley.
With just us, we cannot break through it, so we can only resort to trickery..."
...
After a day, all the cultivators hidden on the deserted island were ready. There were over a dozen Void Refining cultivators and more than a hundred Soul Transformation cultivators. Although there were no Integration stage powerhouses, it was still a not weak force.
On the other side, Xiao Fei, Xiao Lan, and Huang Feifei had already quietly infiltrated the outer perimeter of the horseshoe-shaped island chain.
"Second Sister, I still have some giant's essence blood here. I'll give it all to you."
Xiao Fei took out a large pile of bottles and jars, all containing essence blood decomposed from giants.
Substances like essence blood were great tonics for ghost cultivators like Xiao Lan.
"The undead are powerful and irresistible. You only need to attract their attention; I will handle everything else."
"I know! Hurry up and go. If you wait any longer, the heavenly tribulation will descend, and it will strike you down too!"
Xiao Fei was still a little worried, but time was short, and it wasn't the moment for lingering. He could only wave goodbye.
After watching Xiao Fei and Huang Feifei leave, Xiao Lan opened a bottle filled with essence blood.
Innumerable blood threads extended from her body and burrowed into the bottle. Soon, all the essence blood in the bottle was absorbed.
Xiao Lan tossed the empty bottle aside and swaggered towards the island.
"Halt! What ghost are you?"
Two zombies poked half their bodies out of the ground and shouted interrogatively.
Xiao Lan ignored them, opened her crimson lips, and blew a breath towards the two zombies. A gust of eerie wind swept through, and the souls of the two zombies were instantly annihilated.
After she killed the two zombies, other patrolling undead immediately discovered her and flew towards her, simultaneously emitting wails to alert their companions.
Countless zombies and skeletons converged on Xiao Lan. Without a word, Xiao Lan directly attacked.
Innumerable blood threads danced, ghost mist surged, and the scene was grand, causing the approaching undead to cry out in agony and attracting more undead to join the fray.
But this was still far from enough!
She needed to lure over all the Integration stage powerhouses.
Xiao Lan's gaze swept across the surroundings. She took out several more jade bottles filled with essence blood, and her blood threads extended into them, absorbing greedily.
With the replenishment of this essence blood, her aura surged, quickly breaking through the critical point and reaching the Integration stage.
After her strength surged, Xiao Lan's ghost mist swept through a group of skeletons. The souls of all the skeletons were devoured by her, leaving behind only scattered piles of white bones.
Dense blood threads shot out from underground, entangling a large group of zombies into cocoons of blood.
A moment later, the blood threads dispersed. All the zombies were dead beyond any possibility of revival.
After killing the zombies and skeletons in front of her, Xiao Lan flew directly towards the mountain peaks on the island.
All the mountain peaks of the horseshoe-shaped island chain were connected by a large formation, enclosing the valley.
Xiao Lan's earlier fierce killing had already alerted the other Integration stage experts stationed there. They were all rushing towards her.
"Heh heh heh! Fellow Daoist, as a ghost cultivator, why are you betraying your own kind and helping the cultivators of the Heavenly Origin Realm?"
A zombie at the Integration stage landed in front of Xiao Lan, blocking her path.
"Why not surrender to us now? We can overlook your past transgressions!"
At this moment, another Integration stage skeleton drilled out from underground, blocking her retreat.
"I was born here, I grew up here, naturally, I am a cultivator of the Heavenly Origin Realm!"
Xiao Lan remained unfazed and continued to walk forward.
As she neared the zombie in front of her, her body suddenly exploded, transforming into ghost mist and blood threads that burrowed into the ground.
When she reappeared, she was already behind the zombie.
"Stop her!"
At this moment, several more Integration stage powerhouses arrived, surrounding and intercepting Xiao Lan.
Xiao Lan belonged to the spirit body category, inherently unpredictable and the most difficult to deal with.
She had also gained the blood threads, compensating for the shortcomings of her spirit body in terms of combat power.
Currently, over ten Integration stage powerhouses had come to intercept her, yet Xiao Lan remained as elusive as a loach, moving with ease amidst the crowd. It would be difficult to capture her in a short time.
As time passed, more and more undead powerhouses arrived, forming layers upon layers, completely surrounding the island.
"Now, where do you think you can run!"
"Die!"
Xiao Lan was finally cornered by the numerous powerhouses, with nowhere left to escape.
Just then, Xiao Lan suddenly reached up and tore off several talismans that Xiao Fei had previously affixed to the top of her head.
Instantly, an aura shot straight into the sky. Tribulation clouds gathered in the sky, and countless golden lightning dragons roamed within them.
"Ah! Heavenly Tribulation!"
"Run!"
"You lunatic!"
Everyone present was an undead being and had suffered enough from heavenly tribulations. Each time, they barely escaped with their lives.
Seeing the golden tribulation lightning in the sky, they were instantly terrified and lost all will to fight, turning to flee.
But Xiao Lan did not want them to leave; she wanted them to stay and endure the lightning strikes with her.
Her body completely disintegrated, transforming into countless blood threads that spread out, entangling every Integration stage expert.
Although this action could not alleviate her pain, having others suffer with her made it much more bearable.
As Xiao Lan's aura became entangled with these experts, they were all locked onto by the tribulation lightning.
The tribulation lightning in the sky did not distinguish between them, directly striking golden tribulation lightning at every location where Xiao Lan's aura was present.
These experts, dragged down by Xiao Lan, could only unleash their full power to resist the golden tribulation lightning, which grew stronger with each strike.
...
The cultivators of the Heavenly Origin Realm guarding the deserted island waited for a long time, finally detecting intense fighting occurring outside the horseshoe-shaped island chain.
After a while, countless golden tribulation lightning strikes followed, engulfing the entire area in a sea of lightning.
"Everyone, follow me and charge over!"
The group of cultivators remaining on the island had waited for a long time. Now, filled with fighting spirit, they flew towards the valley entrance.
As soon as they arrived, they engaged in fierce battles with the zombies and skeletons guarding the area.
