Fen Tian Demon Venerable's strength was naturally extremely powerful.
However, Ye Qing, Dongfang Yue, and Yu Xiaodao joined forces and erupted with a very heaven-defying battle strength.
Those Spirit Emperor Realm warriors who rushed over were unable to resist the terrifying attacks of the three people at all.
In the blink of an eye, the three big shots rushed to Fen Tian Demon Venerable's side.
Fen Tian Demon Venerable's body released an extremely terrifying energy fluctuation.
The Fen Tian Demon Fire was released again.
In the void, a Fen Tian Demon Palm, with an indescribable terrifying attack, suddenly bombarded towards Ye Qing's body.
Obviously, Fen Tian Demon Venerable had already seen that the key to breaking the attacks of the three people present was Ye Qing.
As long as he could kill Ye Qing, the remaining two people were nothing to be afraid of.
Therefore, Fen Tian Demon Venerable focused all his attacks on Ye Qing, wanting to kill him.
"Rumble!"
Above Ye Qing's head, a small yellow book floated out, blooming with a brilliant light.
Three levels of amplification were suddenly provided.
Ye Qing's Ultimate Eternal Spirit Art, Demon Slayer Art, released an extremely terrifying power, and the Epic Killer Book also provided a threefold amplification.
However, just as Ye Qing was about to go on a killing spree, the Epic Killer Book in the sky quickly leveled up to the fourth level.
Since entering the Sky Devil Region, Ye Qing did not know how many big shots he had killed.
Ye Qing had killed many experts at the peak of the Ninth Level Spirit Emperor Realm.
Although killing a Ninth Level Spirit Emperor Realm expert was not enough to raise the quality of the Epic Killer Book.
However, if he killed a bunch of them, it would be completely different.
In the Sky Devil Area, Ye Qing had killed at least 30 experts of the ninth level of the Spirit Emperor Realm.
There were also other Spirit Emperor Realm experts who had died in the hands of Ye Qing.
Currently, the Epic Killer Book had been upgraded to the fourth level.
This Epic Level Killer Book was extremely terrifying.
Boom!
With four layers of amplification, Ye Qing's Demon Slayer Art had become terrifyingly powerful.
It had exceeded the limit!
Soon, the pitch-black sabers in the sky slashed down from the sky.
Originally, there were many scattered pitch-black sabers, but soon, they all gathered together.
It condensed into a huge pitch-black broadsword.
All of a sudden, it slashed down!
"Chi la!"
Fen Tian Demon Venerable's body crumbled once again. He was no longer able to fight against Ye Qing.
Not long ago, Burning Heaven Demon Venerable's physical body had completely collapsed under Ye Qing's ferocious attacks.
Although Burning Heaven Demon Venerable's life essence was still vigorous, under the suppression of the Demon Slaughter Art, he had already been completely defeated.
Even Burning Heaven Devil Venerable's soul did not manage to escape and died in the hands of Ye Qing!
A First Level Spiritual Elder was completely dead.
The rest of the Heavenly Demons in the Spirit Emperor Realm were all terrified.
They never thought that the powerful Burning Heaven Demon Venerable, the number one general under the Ancient Heavenly Demon, would actually die!
Without Burning Heaven Demon Venerable, the remaining Heavenly Demons in the Spirit Emperor Realm did not have the courage to continue fighting with Ye Qing.
"Retreat!
Retreat quickly! "
"Brothers, let's go!"
Screams sounded one after another. The pitch-black broadswords released by Ye Qing, Dongfang Yue, and Yu Xiaodao killed many Heavenly Demons in the Spirit Emperor Realm.
The Ancient Heavenly Demon City was filled with the smell of blood.
Ye Qing killed a bunch of big shots. The light released by the Epic Killer Book in the sky became even more dazzling.
Although it could not break through to the fifth level, there was still a lot of enhancement.
At present, the Epic Killer Book could provide a fourfold increase in damage, which was already very terrifying.
In his heart, Ye Qing was very satisfied.
"Kill!"
Ye Qing said simply, and a cold light bloomed in his eyes.
He did not have any good impression of the Heavenly Demons present at all. He just wanted to kill them all.
If Ye Qing did not kill them now, they would probably come to find trouble with Ye Qing in the future.
Soon, more than half of Burning Heaven Demon Venerable's subordinates died.
Many Heavenly Demons were running away.
However, under the fierce attacks of Ye Qing, Dongfang Yue, and Yu Xiaodao, those Heavenly Demons could not resist at all. They all died.
In the process, many treasure chests also dropped. However, there was not a single Blood Soul Treasure Chest.
Ye Qing was a little helpless.
Just as Ye Qing spread out his hands, all of a sudden, a bright light bloomed in his eyes!
Because, at the place where Burning Heaven Demon Venerable died, a large Blood Soul Treasure Chest dropped!
Ye Qing had never seen a treasure chest above the Blood Soul Treasure Chest. In theory, killing a Spirit Venerable Realm big shot would have a chance of dropping something better than a Blood Soul Treasure Chest.
However, that chance was too low.
It would be very good if a super large Blood Soul Treasure Chest could drop.
At present, Ye Qing had already obtained two super large treasure chests.
He only needed one more to complete the mission issued by the system.
In the Ancient Heavenly Demon City.
The Heavenly Demon elites were all dead.
Ye Qing left quickly with Dongfang Yue and Yu Xiaodao.
Since he had already killed Burning Heaven Demon Venerable, there was no need for Ye Qing to stay in the Ancient Heavenly Demon City and waste time.
There were other Heavenly Demons in the Ancient Heavenly Demon City.
However, their strength was only in the Spirit Grandmaster Realm. They could not arouse Ye Qing's interest at all.
"Rumble!"
Just as Ye Qing, Dongfang Yue, and Yu Xiaodao were about to leave, suddenly, in the sky, an extremely powerful aura swept over and suppressed the world.
Ye Qing's expression changed drastically.
It was not someone from the Ancient Heavenly Demon City.
It was a Heavenly Demon from outside.
On Ye Qing's face, a cold and gloomy light appeared.
There were a total of 100,000 Heavenly Demons outside.
It was terrifying!
Moreover, the aura released by those 100,000 Heavenly Demons was extremely terrifying.
A monstrous demonic aura was emitted from the 100,000 Heavenly Demons.
Ye Qing, Dongfang Yue, Yu Xiaodao, and Ah Kun all looked surprised.
They did not expect that there were only 3,000 Spiritual Emperor Realm Heavenly Demons before.
Now, they had encountered 100,000 Heavenly Demons. This lineup was a little terrifying.
Of the 100,000 Heavenly Demons, more than half were Spiritual Emperor Realm Heavenly Demons.
It was almost impossible to kill all of them.
100,000 Heavenly Demons!
Even though Ye Qing and the others' combat strength was extremely terrifying.
They still could not kill all of them!
Before Ye Qing could kill them, they would probably be exhausted to death.
After all, Ye Qing was only at the fourth level of the Spirit Grandmaster Realm. If he were to fight 100,000 Heavenly Demons, killing a few thousand would be the limit.
"Run!"
Ye Qing's heart moved, and he shouted to the brothers around him.
Soon, Ye Qing's figure disappeared.
In terms of running speed, Ye Qing was still very amazing.
There was also Dongfang Yue, Yu Xiaodao, and Ah Kun. Their running speed was also very monstrous.
"Kill, kill them!"
"They actually killed Senior Burning Sky Demon Venerable!"
"Brothers, let's go!"
100,000 Heavenly Demons quickly rushed over. Monstrous demonic aura was released from their bodies, covering the sky and the sun.
Among them, there were a few big shots at the peak of the ninth level of the Spirit Emperor Realm. They were quite fast at running.
There were about 30 of them who were the first to catch up.
