The Imperial Master and the seven human commanders were already unable to protect themselves, let alone cover the retreat of the human army.
And those Blood God Sons in the Soul Refining Realm continued to release various poisonous plagues and black energy of death, pouring them onto the battlefield below.
Hundreds of thousands of the human army that was retreating in panic were enveloped by the overwhelming black air and poisonous mist, and were soon corroded into bones and blood.
In addition, several Blood God Sons also used the power of the Nine Tribulations to unleash earthquake tribulations, flood tribulations and flowing fire tribulations.
On the battlefield with a radius of hundreds of miles, a huge earthquake suddenly occurred, the mountains collapsed and the earth collapsed, and the sky collapsed.
There were even endless floods gushing out from the ground, rolling up huge waves and drowning countless human armies.
Wisps of flames were also floating in the sky, forming balls of violent fireballs and blasting towards the human army below.
The loud sound of "rumbling" is endless, and the earth-shattering power is like the end of the world.
Every moment, thousands of human soldiers died, leaving no intact corpses.
If things continue like this, by the time the more than three million humanoid army retreats to Tianlong Pass, they will probably be dead and wounded long ago and the whole army will be wiped out.
Seeing that the situation was so critical, Ji Tianxing rushed towards the powerful demons without hesitation.
He used the Divine Hidden Step to approach a Blood God Son invisibly, and launched a brazen attack thousands of feet behind him.
"Draw your sword!"
He held the Heavenly Burial Sword in his right hand and suddenly drew the sword and swung it out.
A huge sword light that was ten feet long and filled with purple light instantly crossed the sky of a thousand feet and struck the Blood God Son.
The Blood God Son in the Soul Refining Realm didn't react at all, let alone have time to dodge, before he was slashed to pieces by the thunderous sword light.
"Bang!"
The huge body was shattered into pieces and turned into tens of thousands of bloody fragments, wrapped in dense thunder and lightning.
As a burst of thunder exploded, countless bloody fragments were killed by the violent thunder, and collapsed and dissipated on the spot.
This Blood God Son, who was at the fifth level of the Soul Refining Realm, was instantly killed by Ji Tianxing with one sword and was completely wiped out!
Although, the power of the Nine Heavens Divine Thunder is not enough to severely damage the Blood God Son in the Yuanshen realm.
However, against the Son of Blood God in the Soul Refining Realm, Nine Heavens Divine Thunder has absolutely invincible power.
The sudden turn of events shocked the other Blood God Sons and the Demon Commander, and they all showed horrified expressions.
They quickly turned around and released their soul power, searching for Ji Tianxing's figure.
But Ji Tianxing used the Divine Hidden Step again and quietly rushed to the side of another Blood God Son.
"call out!"
Another sword stabbed out, and a bit of cold light suddenly appeared and disappeared quickly.
The next moment, cold light bloomed in the body of the Blood God Son, and there was an earth-shaking loud noise.
"boom!"
Dazzling cold light, accompanied by brilliant purple thunder, rose into the night sky and turned into a huge mushroom cloud.
Coincidentally, this mushroom cloud covered a ten-mile radius, covering both Blood God Sons.
The terrifyingly powerful sword light and violent masculine thunder instantly blasted the two Blood God Sons into pieces.
When the sword light and thunder light dispersed, both Blood God Sons were completely wiped out.
Ji Tianxing disappeared again and began to assassinate several other Blood God Sons.
Such a scene frightened the Mingye Demon Commander and others. They did not dare to attack the Emperor Master and others with all their strength, and they were all on alert.
The emperor's master and several human commanders were suddenly relieved and secretly breathed a sigh of relief.
Although, they did not see Ji Tianxing.
But they knew that someone strong was coming to help, and it must be Ji Tianxing.
In the human camp, only Ji Tianxing has mastered the power of divine thunder and can kill a Blood God Son with one sword!
Just a few breaths later, Ji Tianxing found another opportunity and launched a fatal attack.
There is no doubt that another Blood God Son died under the Sky Burial Sword and was wiped out on the spot.
The Demon Commanders and Blood God Sons became increasingly frightened, gradually tightened the encirclement, and joined forces to guard the surrounding areas.
The Night Demon Commander roared angrily, controlled a huge black ghost flag, and cast a powerful secret technique.
He summoned tens of thousands of demon ghosts, blocking the sky for dozens of miles, vowing to find Ji Tianxing.
However, with the strength of several Demon Commanders and Blood God Sons, it was impossible to see through Ji Tianxing's Divine Hidden Step.
Within the next few dozen breaths, Ji Tianxing attacked four times in a row, killing all four Blood God Sons with only four sword strikes.
All the Blood God Sons in the soul refining realm were killed, leaving only a few demon commanders and soul refining experts, all of whom were so frightened that their livers and gallbladders were split and their souls were trembling.
When Ji Tianxing took action for the fifth time, another Demon Commander was instantly killed on the spot.
The number of strong demons continued to decrease, and Demon Commander Ming Ye and others had begun to retreat, turned around and fled away.
The morale of the Imperial Master and the human commanders was greatly boosted, and they were all extremely grateful to Ji Tianxing.
Ji Tianxing was about to chase Mingye Demon Commander and others when the Imperial Master shouted loudly: "Tianxing, don't chase them, it's more important to cover the retreat of our army!"
Ji Tianxing quickly looked at the battlefield below and saw millions of undead skeletons and tens of millions of demon troops, frantically chasing the human army.
Just during this time, another 200,000 human soldiers died tragically on the battlefield.
The number of the human army has declined to only about three million.
So, he gave up chasing the Dark Night Demon Commander and others and rushed towards the battlefield below.
"Whoosh!"
In a few breaths, he flew above the demon army.
Looking at the army of undead skeletons charging at the front, he sacrificed the Tiangang Divine Fire Cauldron without hesitation, held the magic formula with both hands, and controlled the divine cauldron to launch an attack.
"Introduce the Heavenly Gang, pour down the earth's fire, burn all things, kill the gods and destroy the demons!"
Under his control, the Tiangang Divine Fire Cauldron flew into the sky, expanded violently to the size of a palace, and burst into the sky with silver-white brilliance and dark red fire.
The huge divine cauldron tilted slowly, and overwhelming dark red fire poured out from the cauldron's mouth, pouring down on the battlefield below like a torrential flood.
"boom!"
The endless ground fire drowned hundreds of thousands of undead skeletons, and immediately spread and turned into a vast sea of fire.
Immediately, those undead skeletons who were not afraid of death and bravely charged were burned to ashes by the violent red fire.
The dark brown mountains, rivers and earth were also melted by the fire into red magma, flowing between the mountains and rivers.
In just a few breaths, most of the millions of undead skeletons were killed.
The demon army that followed the undead skeletons and charged at them was immediately blocked by the blazing sea of fire and had to take a detour or retreat to avoid it.
Ji Tianxing manipulated the divine cauldron again and released the silver-white Tiangang Divine Wind, blowing towards the sea of fire below.
Taking advantage of the wind, the fire spread violently and rapidly, turning a two hundred-mile radius into a world of sea of fire and magma.
The terrifyingly powerful Tiangang Divine Wind condensed into dozens of tornadoes and swept across the battlefield, strangling hundreds of thousands of demon troops in an instant.
