On the edge of the Jinsha Desert are rows of wide caves.

The cave is full of rocks, the ground is uneven, and some potholes, cracks and rocks can be seen everywhere.

Ji Tianxing chased the seriously injured Black Feather, passed through the Jinsha Desert, and fled all the way into the cave.

Originally, he would soon be able to catch up with Black Feather.

But the terrain inside the cave is intricate, full of caves and passages of different sizes.

Black Feather was also here for the first time, and he was not familiar with the situation in the cave.

He was forced to be in a hurry, so he could only flee in a panic, desperately fleeing to the depths of the earth.

And it worked.

A full quarter of an hour passed, and Hei Yu fled thousands of miles deep underground, and was not caught up by Ji Tianxing.

After all, even he didn't know where he would flee or which cave he would go into in the next second.

Ji Tianxing is even more nowhere to be found, and he really can't catch up with him in the short term.

Finally, the two entered the depths of the earth.

The intricate caves seem to have come to an end.

Black Feather, who was fleeing in front of him, suddenly stopped after burrowing out of a wide cave!

His body stiffened in place, looking ahead in horror, and his expression became hideous.

Ji Tianxing hurriedly chased after him, holding the Burial Heaven Sword and was about to attack.

However, when he saw the situation outside the cave, he also stopped.

Outside the wide cave is a clearing with a radius of thousands of feet.

Black Feather was standing at the edge of the clearing, and in front of him was a bottomless abyss!

This abyss is cylindrical in shape, like a deep well magnified a million times, unfathomable.

This super-gigantic 'deep well' is straight and steep, with the bottom leading to the mysterious depths of the earth's core, shrouded in endless flames.

The top of the 'deep well' leads to the surface, thousands of miles high, and it is also filled with endless heavenly fire.

The flat ground under the feet of the two is just a boulder raised from the 'well wall'.

Compared to the huge flame abyss, they were as small as ants!

"Oh my God, how can there be such a huge abyss in the depths of the earth?" Black Feather looked at the abyss with a shocked face, and couldn't help but sigh with emotion.

Ji Tianxing also looked around at the abyss, and thought to himself: "According to legend, there is a real abyss place in the world, connecting the world and hell, and only ghosts and gods can enter and exit.

In the depths of the Flame Mountain, there was such a huge abyss, which really looked like the legendary Netherworld Abyss.

The power and temperature of the flames here are about five times higher than those of the outside world, and they are definitely the source of the glazed heavenly fire!

Could it be ...... This abyss is the true lair of the glazed fire dragon?"

Just when he was full of shock and secretly wondered, Black Feather had already come back to his senses and quietly flew into the abyss.

Black Feather passed through the raging sea of fire, unleashing his divine sense, shrouding the abyss rock walls for hundreds of miles, searching for caves and exits.

Ji Tianxing was awakened by him, and quickly gathered his thoughts, and looked at him coldly.

Seeing him searching for an exit in the abyss, Ji Tianxing couldn't help but show a sneer.

"Black Feather, don't waste your efforts, are you still trying to find an exit and escape from here?"

As he spoke, he pointed to the cave behind him and sneered, "I have already checked it just now, and there is only this one exit in the entire abyss!"

Now you are a turtle in an urn, you can't escape with your wings, so you can die obediently!"

Hearing him say this, Black Feather became even more anxious.

He held the bleeding chest in his left hand and the sword in his right hand, and flew upwards desperately.

Clearly, he believed that the top of the abyss was connected to the surface of the Flaming Mountain.

As long as you fly up the abyss, you will definitely be able to escape from the abyss and return to the Flaming Mountain.

However, how could Ji Tianxing let him get his wish?

"I really don't shed tears when I don't see the coffin!"

He snorted coldly, swung the Burial Sky Sword, and slashed towards Black Feather as fast as lightning.

"Sky Breaking Sword!"

He held the Burial Heaven Sword in both hands, and slashed out a hundred-zhang long sword light with all his strength, breaking through the raging sea of fire and slashing towards the black feather.

Hei Yu was suddenly startled, and hurriedly waved the treasure knife and swept out a few sword lights.

"Bang bang bang!"

The sword light collided with the sword light, and a dull loud sound erupted, reverberating fiercely in the abyss.

The sword and sword shadows collapsed one after another, bursting out in all directions, bombarding the rock wall of the abyss.

However, the surrounding rock walls were all incomparably hard, and after the sword light and sword qi hit, not even a trace was left.

Ji Tianxing couldn't strike a blow, and then swung the Burial Sky Sword, slashing out an overwhelming sword light, enveloping the figure of Black Feather.

Black Feather was held back by him, unable to escape smoothly, so he had to resist with all his might.

The two fought fiercely in the abyss, and both used their mastery to press the bottom of the box.

Suddenly, the brilliant brilliance of mana continued to flicker in the abyss, overshadowing the brilliance of the turbulent sea of fire.

The earth-destroying shock wave dispersed the sea of fire within a radius of dozens of miles, wantonly impacting the rock wall of the abyss.

The loud "boom" and explosions resounded one after another, echoing in the abyss.

The two fought for hundreds of moves, and Hei Yu finally couldn't hold it anymore.

His physical body was on the verge of collapse, and his mana was almost exhausted, and he was about to run out of water.

Ji Tianxing immediately made a decisive move, united the human sword, and carried the phantom of the white tiger with the big mountain, and killed the black feather.

"White Tiger Holy Sword!"

The thousand-zhang giant sword slammed into Black Feather, and the mountain-sized white tiger phantom also drowned Black Feather's figure.

However, the black feather also urged the power of the Heavenly Demon Black Feather Array to form a huge shield.

"Boom!"

With a loud and earth-shattering sound, the White Tiger Holy Sword shattered the black light shield and flew the array disk out.

Black Feather's body was also shattered by the giant sword, turning into pieces of flesh and blood, scattered in the abyss.

A short moment later, the pieces of flesh were burned to ashes by the heavenly fire.

Black Feather's body was destroyed, and only one divine soul remained, and he fled upwards in even more panic.

The White Tiger Holy Sword was also shattered, and Ji Tianxing was shocked and flew out.

His face was pale, blood was spilling from his mouth and nose, and his soul was wounded.

After all, if he fuses with the Burial Heaven Sword and has a hard time with the robbery-level magic weapon, he will definitely suffer a big loss.

But his injuries were not serious and did not affect the fight.

Seeing Hei Yu's divine soul fleeing, he immediately chased after it, sacrificed the thousand-zhang high Yuan Shen Golden Sword, and slashed it with a sword.

"Bang!"

The Yuan Shen Golden Sword carried the endless divine power and smashed Black Feather's divine soul on the spot.

The dignified Black Feather Chairman, the Martial Monarch powerhouse of the Eightfold Tribulation Realm, was killed by Ji Tianxing in this way, and he was wiped out forever!

Black Feather's body and divine soul, as well as his magic weapon and spatial ring, all fell into the abyss and were burned to powder by the heavenly fire.

Ji Tianxing was also tired and panting, and hurriedly withdrew the Yuanshen Golden Sword, preparing to leave the abyss and go to join Yun Yao and the others.

But at this moment, the voice of the burial sky sounded in his head.

"Tianxing, it's already a big surprise that you can find this Heavenly Fire Divine Furnace, how can you just leave?

Now that the materials have been gathered and the Divine Furnace has been found, if the Divine Sword is not repaired at this time, when will it be?"
