The dull voice of the ancestral demon god echoed high in the sky.
Its whole body lit up with a dazzling purple light, emitting an extremely powerful aura that spread in all directions.
The invisible violent air wave swept hundreds of miles around, severely impacting the soldiers of the three tribes.
Without the protection of the ancient sword formation, at least half of the more than three million soldiers would have been killed by the shock.
However, the huge colorful sky blocked the invisible shock wave.
Only a few thousand people were killed by the shock, tens of thousands were injured and vomited blood, and the vast majority remained unscathed.
At the same time, the ancient sword formation was in motion, and endless power passed through the formation's veins and gathered in the center of the formation.
In the end, extremely violent power surged into Ji Tianxing's body.
He is the core of the formation, so he must gather the power of the entire formation to deal with the ancestral demon god.
"Whoosh!"
His whole body lit up with colorful brilliance that reached the sky, and his body was filled with terrifying power and expanded violently.
In just a few breaths, he transformed from a seven-foot-tall human youth into a hundred-foot-tall giant.
The muscles all over his body bulged high, and his body became extremely tall and strong, like a giant beast from the wild, possessing the power to destroy the world.
But this is not the end. As the ancient sword formation continues to operate, everyone's power is still gathering.
His body is still expanding, gradually growing to two hundred feet, three hundred feet, four hundred feet...
Thirty breaths later, when his body finally stabilized, his height had reached five hundred feet, like a thousand-meter mountain!
His strength is also increasing rapidly, and it is comparable to the peak of the ninth level of Yuanshen Realm!
The power of destroying heaven and earth surged through his body, causing his flesh, blood, and meridians to tremble continuously, and his bones also made a crunching sound.
He felt like his body was about to burst, and every inch of flesh and blood in his body felt unbearable stinging and tearing sensations.
The indescribable severe pain caused his face to twist ferociously, and he let out bursts of low roars.
He just wanted to vent the violent power in his body as soon as possible in order to alleviate the pain of his body and soul.
Of course, this is only when the formation keeps running, so he becomes like this and possesses such powerful power.
Once the formation stops functioning, he will quickly return to his original state.
He only uses formations to gather the power of everyone, and cannot directly improve his level of strength.
Before, he was as small as a fly compared to the ancestor demon god.
But now, he is already 30% the size of the original demon god, enough to compete with the original demon god.
The Ancestral Demon God attacked several times, but was unable to kill the armies of the three tribes, let alone destroy the colorful sky.
It then realized that if it wanted to massacre the armies of the three tribes, it must destroy this formation.
The core of this formation is Ji Tianxing, the Emperor, the Golden Dragon Emperor and the Tianluo Demon Emperor.
Only by killing four of them can this formation be completely destroyed.
The Ancestral Demon God looked down at Ji Tianxing, and shouted in a cold and gloomy tone: "Little reptile! I didn't expect you to have some ability to arrange such a wonderful and extraordinary formation.
However, everything you do is in vain!
I think back then, eighteen gods from various races led tens of millions of troops to form a heaven-defying demon-slaying formation, but they were unable to kill this god.
With your large formation and more than three million ants, you want to trap me? How naive!"
The ancestor demon sneered, stretched out four huge arms, waved his palms and shot out palm shadows all over the sky, and shot Ji Tianxing down.
"Suffer death!"
A total of eighty-one purple light palm shadows were as huge as mountains. Carrying the power to kill everything, they descended from the sky towards Ji Tianxing.
In an instant, a hundred miles around was enveloped in purple light, and the figures of Ji Tianxing, Dijun and others were also submerged.
Ji Tianxing was roaring in pain, and when he saw palm shadows all over the sky slapping him down, he waved his fists with all his strength and punched out hard.
"Star-Shattering Fist!"
He finally attacked, and the raging and violent power in his body was finally vented.
Two huge mountain-like colorful fist lights erupted with terrifying power, hitting the palm shadows all over the sky head-on.
Only the muffled sounds of "bang bang bang" were heard, erupting one after another and resounding throughout the sky.
The colorful fist light and purple light palm shadow all collapsed and shattered, turning into overwhelming fragments, which were wrapped in shock waves and spread in all directions.
"Boom!"
Within a radius of more than two hundred miles, more than a dozen mountain peaks were shattered by the shock wave and collapsed into ruins.
Tens of thousands more soldiers were affected and were killed on the spot, losing their lives.
But this casualty is negligible for the armies of the three tribes.
Everyone went all out to explode their strength, stimulating the operation of the ancient sword formation and increasing Ji Tianxing's strength.
Ji Tianxing's body swelled up again, and the heart-rending pain was felt all over his body, and his whole body began to twitch.
The ancestor of the demon god frowned, his six giant eyes flashed with fierce light, and he shouted in a cold tone: "Little reptile, you really have some skills, no wonder you can kill Yougu..."
Obviously, the ancestral demon god tested Ji Tianxing's fighting ability and was qualified to fight against it, so it put away its contempt and took it seriously.
"The Evil Sword of the Setting Sun!"
The ancestor demon god shouted with a voice like a bell, waved his six arms, and used his broad palm as a blade to slash at Ji Tianxing.
Six thousand-foot-long purple blades, carrying the power of destroying everything, struck at the top of Ji Tianxing's head.
Not to be outdone, Ji Tianxing injected immense power into the Heavenly Burial Sword, causing it to expand and become a 400-foot black giant sword.
He held the huge Heaven Burial Sword in both hands and slashed out with all his strength.
"Canghaihan!"
This sword swept out, and a crescent-shaped sword light about several thousand feet wide erupted from the Sky Burial Sword, sweeping towards the ancestor demon god.
“Bang bang bang bang!”
A series of deafening loud noises erupted, resounding through the sky and shaking the world.
Six giant purple blades were cut into pieces on the spot and splashed out in all directions.
The crescent sword light, which was thousands of feet wide, was still powerful and struck the ancestral demon god hard again.
"Boom!"
Amidst the earth-shaking loud noise, the Crescent Sword Light collapsed on the spot, turning into fragments and splattering all over the sky.
The ancestral demon god was also knocked back ten miles away by the sword light, his body shaking violently and flashing purple light.
However, his huge and sturdy body is made of four divine objects, and its defense is extremely powerful.
Ji Tianxing's sword technique could not hurt him at all.
The ancestor demon stared at Ji Tianxing with cold eyes, the head in the middle shook, and a playful sneer appeared on his ferocious face.
"Hehehe... It's interesting. I have heard from You Gu a long time ago that you, the little reptile, is its number one enemy and the most outstanding evildoer in the human race. You have had an incredible adventure.
Now it seems that this is indeed the case.
Because of this, I will never let you go, I will devour your flesh, blood, and spirit, and deprive you of your lifelong mana and supernatural powers!"
