On the edge of the Jinsha Desert are rows of wide caves.
The cave has rugged rocks, uneven ground, and potholes, cracks and piles of rocks can be seen everywhere.
Ji Tianxing chased the seriously injured Heiyu through the Jinsha Desert and escaped into a cave.
Originally, he could catch up with Black Feather very quickly.
However, the terrain inside the cave is complex, with caves and passages of different sizes everywhere.
It was also the first time for Black Feather to come here and he was not familiar with the situation in the cave.
He was cornered and could only flee in panic, desperately trying to escape deep underground.
This approach is indeed effective.
A full quarter of an hour passed, and Heiyu fled thousands of miles deep underground without being caught up by Ji Tianxing.
After all, even he himself didn't know where he would flee to in the next second or which cave he would crawl into.
Ji Tianxing is nowhere to be found, and it is indeed impossible to catch up with him in the short term.
Finally, the two of them entered the depths of the earth.
The intricate cave seems to have come to an end.
Black Feather, who was fleeing ahead, suddenly stopped after getting out of a wide cave!
His body froze in place, looking forward in horror, and his expression became ferocious.
Ji Tianxing hurriedly chased after him, holding the Heavenly Burial Sword and about to attack.
However, when he saw the situation outside the cave clearly, he also stopped.
Outside the wide cave is an open space thousands of feet in diameter.
Black Feather stood at the edge of the clearing, and in front of him was a bottomless abyss!
This abyss is cylindrical, like a deep well magnified a million times, and is unfathomably deep.
This super huge 'deep well' is straight and steep, and the bottom leads to the mysterious depths of the earth, shrouded in endless flames.
The top of the 'deep well' leads to the surface, which is thousands of miles high, and is also filled with endless sky fire.
The flat land under their feet was just a huge boulder protruding from the 'well wall'.
Compared with the huge flame abyss, their bodies are as small as ants!
"Oh my God! How could there be such a huge abyss deep in the heart of the earth?" Heiyu looked at the abyss in shock and couldn't help but sigh.
Ji Tianxing also looked around at the abyss, thinking to himself: "According to legend, there is a real abyss in the world, connecting the world and hell, and only ghosts and gods can enter and exit.
Deep underground in the Flame Mountain, there is such a huge abyss hidden, it really looks like the legendary Netherworld Abyss.
The power and temperature of the flames here are about five times higher than those in the outside world. They are definitely the source of the glazed sky fire!
Could it be that...this abyss is the real lair of the Glazed Fire Dragon?"
Just when he was filled with shock and thinking secretly, Black Feather had come to his senses and quietly flew into the abyss.
Black Feather passed through the raging sea of fire and released his spiritual consciousness, covering the abyss rock walls with a radius of hundreds of miles, looking for caves and exits.
Ji Tianxing was awakened by him, quickly gathered his thoughts, and looked at him with cold eyes.
Seeing him searching for an exit in the abyss, Ji Tianxing couldn't help but sneer.
"Heiyu, don't waste your efforts. Do you still want to find an exit and escape from this place?"
As he spoke, he pointed to the cave behind him and sneered: "I just checked, there is only one exit in the entire abyss!
Now you are a turtle in a urn, unable to escape even if you don’t have wings, so just accept your death!"
Hearing what he said, Kuroyu became even more anxious.
He covered his bleeding chest with his left hand, held the sword in his right hand, and flew upwards without caring about his own life.
Obviously, he believed that the top of the abyss was connected to the surface of the Flame Mountain.
As long as you fly upward along the abyss, you will definitely be able to escape from the abyss and return to the Flame Mountain.
But will Ji Tianxing let him get his wish?
“I really can’t shed tears until I see the coffin!”
He shouted coldly, swung the Heaven Burial Sword, and struck at Black Feather as fast as lightning.
"Heaven-Breaking Sword!"
He held the Heavenly Burial Sword in both hands and slashed out a hundred-foot-long sword light with all his strength, breaking through the raging sea of fire and slashing towards Black Feather.
Black Feather was immediately startled and quickly waved his sword, sweeping out several rays of light.
“Bang bang bang!”
The light of the sword collided with the light of the sword, causing a dull loud noise that reverberated fiercely in the abyss.
The swords, lights, and shadows collapsed one after another, splashed out in all directions, and bombarded the rock walls of the abyss.
However, the surrounding rock walls were extremely hard, and even after being struck by sword light and sword energy, not even a trace was left behind.
Ji Tianxing failed with one strike, so he swung the Sky Burial Sword again, sending out an overwhelming sword light that enveloped Hei Yu's figure.
Black Feather was dragged down by him and could not escape smoothly, so he had to resist with all his strength.
The two started a fierce battle in the abyss, and both used their unique skills.
Suddenly, colorful mana brilliance continued to flicker in the abyss, overshadowing the brilliance of the raging sea of fire.
The shock wave that destroyed the world dispersed the sea of fire within a radius of dozens of miles and hit the rock wall of the abyss wantonly.
Loud "rumbling" sounds and explosions sounded one after another, echoing endlessly in the abyss.
The two of them fought for hundreds of moves, and Kuroyu finally couldn't hold on any longer.
His physical body was on the verge of collapse, his magic power was almost exhausted, and he was about to run out of resources.
Ji Tianxing immediately used his special skill, combining his sword and man's sword, and carrying the phantom of the mountain-sized white tiger, he attacked Heiyu.
"White Tiger Holy Sword!"
The thousand-foot giant sword struck Heiyu with a bang, and the phantom of the mountain-sized white tiger also drowned Heiyu's figure.
However, Black Feather also mobilized the power of the Tiansha Black Feather Formation to form a huge shield.
"Boom!"
With a shocking loud noise, the White Tiger Holy Sword shattered the black light shield and flew the array disk away.
Black Feather's body was also torn to pieces by the giant sword, turning into pieces of flesh and blood, scattered in the abyss.
In just a short moment, those pieces of flesh and blood were burned to ashes by the sky fire.
Black Feather's physical body was destroyed, leaving only a spiritual soul, and he fled upwards in even greater panic.
The White Tiger Holy Sword was also shattered, and Ji Tianxing was knocked out.
His face was pale, blood overflowed from his mouth and nose, and his soul was traumatized.
After all, if he merges with the Sky Burial Sword and goes head-to-head with a calamity-level magic weapon, he will definitely suffer a big loss.
But his injury was not serious and did not affect the battle.
Seeing Black Feather's soul running away, he immediately chased after him, took out his thousand-foot-tall Yuan Shen Golden Sword, and slashed it away with one blow.
"Bang!"
The golden sword of the primordial spirit carried endless divine power and shattered Heiyu's soul on the spot.
The dignified President Black Feather, a powerful warrior at the eighth level of the Tribulation Realm, was killed by Ji Tianxing and was wiped out forever!
Black Feather's body and soul, as well as his magic weapon and space ring, all fell into the abyss and were burned to powder by the sky fire.
Ji Tianxing was also panting from exhaustion, and quickly took back the golden sword of the soul, preparing to leave the abyss and join Yun Yao and the others.
But at this moment, Zangtian's voice sounded in his mind.
"Tian Xing, it's a huge surprise for you to find this Heavenly Fire Divine Furnace, how can you leave just like that?
Now that the materials have been gathered and the divine furnace has been found, if we don’t repair the divine sword now, how long will it take?”
