Yang Song had not joined the battle yet, so he had time to think about various things. Among all the things, he was keenly aware that the boss had not appeared yet.

The abyssal demon boss that appeared last time was quite strong enough, so Yang Song estimated that the boss this time would be stronger or just more in number.

Although there were many Grandmasters here, they were busy fighting with the other abyssal demons after all. Hence, by the time the bosses came, Yang Song estimated that they would not be full in energy at all.

Actually, with Yang Song's strength, he could hide somewhere and just let everyone else deal with it. But it was not the best way after all. In addition, as an immortal cultivator, the more good deeds he did, the more likely that he would not be bound with the dark side of the "cause and effect".

Even though Yang Song was not a good person in nature, he was not a villain either. What's more, if the abyssal demons successfully conquered Blue Star, there would be no place for him to live either.

Therefore, in the end, it was inevitable that he had to kill these abyssal demons.

After all these thoughts, Yang Song took a deep breath and took out several flags from his storage space.

Seeing this, Li Wanjing who was by his side was stunned and wondered what Yang Song wanted to do with these strange flags.

But Yang Song did not explain anything, he just said, "I need to be alone."

Li Wanjing immediately made a gesture towards the people around and left the room together.

Yang Song placed his attention on the flags he had just taken out.

Yes, he planned to deploy the Innate Blood Demon Killing Formation!

Since he estimated that the abyssal demon boss that would come out this time wouldn't be so simple, then he naturally couldn't battle with the other party with his strength alone.

The only way he could think of was to deploy the killing formation.

But there was a tricky thing about this too. That was, he did not when would the boss appear, hence, his current action was equivalent to an act of gambling.

If the boss appeared now, then he could only stop refining the formation flags and go out to battle with those people.

With this, Yang Song focused on refining the eight formation flags entirely.

…

Outside.

As if the abyssal demon's side knew that the situation here was dire, more abyssal demons suddenly came out of the spatial crack.

Xiang Qingsu exerted her full energy and killed the abyssal demons wildly.

More mystic warriors also joined the battle constantly, but compared to the abyssal demon's side, the human's side was noticeably weaker in terms of newcomers.

The rumbling sound made the whole Martial City tremble. The smell of blood was everywhere.

Buildings and many other properties were damaged seriously and corpses of humans and abyssal demons were scattered here and there messily.

The seven Grandmaster martial artists also tried their best to kill the abyssal demons.

A while later, the battle became even more intense and both sides were desperate to win the battle.

But with the passage of time, the human warriors began to become weaker as their energy was drained from the battle.

However, no one noticed that an invisible figure was running here and there around the three big spatial cracks quickly.

The figure was naturally Yang Song.

At the moment, he was drawing the formation symbols around.

The size of the formation this time was very big, so it took a while to draw the formation symbols.

When Yang Song arrived at the final place that he had to draw the symbol, a loud noise burst out from the three spatial cracks.

Yang Song's heart jumped and he quickly drew the symbol.

At the same time, a kind of chaotic and strong energy fluctuation shot out from the three spatial cracks. Then, a big black hand appeared from the spatial crack, making everyone's hair stand on end.

Just as everyone was nervous enough, the other two spatial cracks also suddenly manifested a similar sight.

Soon, three huge stalwart abyssal demons completely came out of the spatial cracks.

The three abyssal demons had different appearances, but their breaths were more or less similar.

The abyssal demon in the middle had the head of a cow and a golden body. His appearance reminded everyone of the previous demon boss, Holy Cow!

But this one looked even more robust and stronger than the Holy Cow.

The abyssal demon on the left had a pair of black wings behind his back, and he had the head of a frog.

The abyssal demon on the right was the smallest compared to the other two, but his appearance was the most eye-catching. He was a like big fluffy while ball.

But no one was stupid enough to blend this guy with the cute and harmless creature.

The cow demon was holding a three-headed spear in his right hand, his eyes glanced arrogantly at the humans around and he said suddenly, "Moo, I did not expect that you lowly ants could kill my little brother. This time, I will break all of you into pieces!"

However, no one had time to care about him, everyone was busy fighting.

Just as the cow demon was about to say something, his cow face suddenly changed and a bad premonition took place in the depth of his heart.

Noticing this expression, the other two demons looked at him strangely and asked, "What is it?"

"Don't you feel it?"

"Feel what?"

"The bad omen."

"Wait, how come there's a familiar yet unfamiliar feeling here?" The fluffy ball muttered.

"I also feel the same," the cow demon nodded in agreement.

Just as they were wondering about it, a buzzing sound caught their ears out of blue, and strange energy spread around in the air.

The abyssal demons up and down, as well as the mystic warriors, suddenly paused and looked towards the source of the sound.

A red dot that couldn't be detected with naked eyes appeared and zoomed in suddenly.

That red dot became a big red ball. The red ball then fell to the ground like a drop of water.

Then, a frightening scene appeared in everyone's sight. When that red ball touched the corpses of the abyssal demons, the corpses of the abyssal demons were gobbled up by it.

The red ball became bigger and bigger.

Soon, just when everyone was dumbfounded by this, a magical yet terrifying scene appeared.

The big red ball suddenly flickered and it became a bloody light.

All the layouts hundreds of meters around disappeared. The flowers, plants, buildings, cars, and so on except for the corpses and living things disappeared.

Only a boundless bloody color was present in everyone's sight.

The ones who were in it felt more profound.

The whole world only had a bloody mist, it was as if they had come to the legendary "purgatory".

The air was filled with a bloodthirsty and violent breath, which made people and even the three abyssal demon bosses shiver subconsciously.

Now, the three abyssal demon bosses realized that something was really wrong here, so they turned around and wanted to go back to the spatial cracks.

But they were shocked to find out that even the spatial cracks that were behind them earlier had also disappeared.

"This… this is…" The cow demon felt extremely shocked about this.

"This is the formation of the cultivators!" The fluffy ball said with a horrified face.

"There are cultivators in this certain world? How come…"

"Isn't this just a low-level martial world? How come there are immortal cultivators?"

The humans around also heard what the three demons were talking about, although they did not catch all of it, the word "immortal cultivator" caught their attention the most.

Then, just as everyone was in a state of confusion, an even more shocking sight manifested and almost took their souls away.

"What the hell is that?!"

Everyone followed the voice, and followed the direction of the person's finger to look towards the sky, only to see an extremely huge figure with two horns on its head, like an ancient demon god.

Although it was a figure, it was covered in blood as if it had just woken up from the sea of blood. The people here could not see its face when they looked up. Simply put, there was no face on this figure at all, only a brutal and violent breath could be felt.

"Roar…"

The low and deep roar woke up everyone.

The three demon bosses were the most frightened when they saw this terrifying figure.

"This… isn't this the Blood Demon Race? How come there's a Blood Demon Race in this formation?"

"Wait, has the Blood Demon Race went extinct a long time ago? What the hell is wrong with this world?"

The three demon bosses were huge enough, but compared to that bloody figure, they were no different from a baby and a bodybuilder!

Then, a huge shadow suddenly covered their figures. The hand of the big bloody demon swooped down without giving out a warning, slapping the three demons away in a burst of exclamation.
