Su Jingxing rested for a moment, then stood up and circulated the Six Comets Records to deduce the exact location of the Half-Demon Overlords of the three kinds of demonic creatures—— Bone Demon, Snake Demon, and Sword Demon.

There were many Half-Demons, but there were limited Half-Demon Overlords.

In total, there were only about 50 Half-Demon Overlords.

Su Jingxing had to get rid of these 50 Half-Demon Overlords no matter what.

With the three Ancient Demons gone and all the Half-Demon Overlords wiped out, the plan of the demonic creatures to invade the surface would end before it even began.

The remaining Half-Demons were killed whenever he encountered them. Those who didn’t meet him were lucky.

As for the demon slaves, there were billions of them. Su Jingxing really didn’t have the strength or time to annihilate them.

Even if the demon slaves were killed, no Function Cards would be extracted.

Therefore, he might as well let them live and keep them in the Little Demon World to slowly clear them out.

Of course, it would be best if the armies of the various countries came in to exterminate them. The threat of demon slaves was limited, and they were the best subjects for training.

Su Jingxing only needed to take care of the Half-Demon Overlords.

Hence.

His physical body traversed through space. Under the guidance of the heavenly secret arts, Su Jingxing was spot on with finding every single one.

With 300 years of spiritual essence cultivation, no Half-Demon Overlord could withstand a punch from him.

If the Half-Demon Overlord wasn’t dead, Su Jingxing wouldn’t be able to feel at ease even if he used Vast Ocean to absorb the demonic energy.

Under such circumstances, more than half of the Half-Demon Overlords of the three types of demonic creatures, Bone Demon, Snake Demon, and Sword Demon, quickly died.

The remaining half did not dare to stay in the Little Demon World after receiving the news.

They ran towards their respective Doors of Darkness and headed for the human world through them.

They couldn’t stay in the Little Demon World anymore. There might be a chance of survival if they escaped to the human world.

Of course, in the Door of Darkness controlled by the Bone Demon, the Snake Demon’s body was writhing crazily, blocking most of the door. Seeing this from afar, the Half-Demon Overlords decisively turned to the other Doors of Darkness.

…

Furious Dragon River.

At the border of the Zheng Nation and Wei Nation, downstream of the waters, beneath a mountain peak that was thousands of feet tall by the river.

Luo Ao and the Wei Nation’s Martial Sage were killing a group of demon slaves and Half-Demons that had come out from the Door of Darkness.

All of a sudden——

Whoosh!

Beams of light shot out.

Six figures passed through the Door of Darkness in a sorry state and revealed themselves.

Four of them were Snake Demon Half-Demon Overlords, and two were Sword Demon Half-Demon Overlords.

Among the six Half-Demon Overlords, the weakest was in the first class of the Void Soul realm.

Six of them appeared at once, and a terrifying aura erupted with a bang, causing Luo Ao and the Wei Nation’s Martial Sage to retreat with grim expressions.

“What’s going on? Why did so many powerful demonic creatures suddenly appear?” Luo Ao growled, his face ashen.

“Now is not the time to worry about why they’re out here.”

The Wei Nation’s Martial Sage also shouted in a low voice, “What’s important now is how to destroy them! Brother Luo, have you contacted your master? There are more and more powerful demonic creatures, and the other demonic creatures seem to be endless. Without the help of Sword Sage Pei, we won’t be able to guard this place at all!”

“I’m already contacting him.”

Luo Ao gritted his teeth. “When Master entered the dark area of the Void World, I’ve been contacting him through the Kingdom Defending Jade Seal.”

At this moment, Luo Ao had entered the Demon’s Den with his physical body, not his Essence Soul. His Essence Soul was still in the Void World, and it was contacting Sword Sage Pei with the Kingdom Defending Jade Seal.

Originally, according to normal circumstances, one would not enter the darkness of the Void World unless they had reach the Soul Platform realm.

However, Sword Sage Pei, who was in the Primordial Spirit realm, did not know these secrets. Secondly, he was skilled and bold. Without building a Soul Platform, he barged into the dark area of the Void World and had yet to step out.

No one knew where Sword Sage Pei had gone or where he was in the dark area of the Void World.

No one knew where Sword Sage Pei’s physical body was too.

That was fine in usual times, but now that the Demon’s Den was in chaos and demonic creatures were constantly coming through the Door of Darkness, Luo Ao and the Wei Nation’s Martial Sage were already starting to struggle. They could not hold on anymore!

…

Luo Ao and the Wei Nation’s Martial Sage were not the only ones who were finding it increasingly taxing.

North Sea.

On an uninhabited island on the coastline of the Xu Nation.

The Martial Sage of the Xu Nation invited the Martial Sage of the Snow Nation, Yu Xiangtian to the bottom of a mountain peak in the center of the island.

More than 700 meters below the island, there was a spacious underground space.

The third Demon’s Den in the Eastern Continent was located in this underground space.

After Su Jingxing exposed the secret, Yu Xiangtian and the Martial Sage of the Xu Nation immediately came to this third Demon’s Den to check on the situation.

Just like Luo Ao’s side, there was no movement at first, but soon, demon slaves and Half-Demons rushed out of the Demon’s Den.

On Luo Ao’s side, most of them were Snake Demons. On Yu Xiangtian’s side, most of them were Sword Demons.

Compared to the Snake Demons, the Sword Demon Half-Demons’ attacks were stronger and more ferocious.

Swish! Swish! Swish!

Hu! Hu! Hu!

Strong winds swept and energy spread.

In the huge underground space, after the Sword Demon Half-Demons appeared, the dome, the four walls of the den, and the ground beneath their feet were soon covered in deep marks.

Yu Xiangtian and the Martial Sage of the Xu Nation could easily deal with them at the beginning, but later on, they had no choice but to join forces.

After the Sword Demon Half-Demon Overlords appeared——

Boom! Boom! Boom! Boom!

The violent attacks and terrifying power, with just three charges, caused the Martial Sage of the Xu Nation’s physical body to vomit blood repeatedly. He was sent flying and crashed into the cave wall, creating a huge pit.

“D*mn it!”

Yu Xiangtian was covered in ice and snow. This was a sign that he had circulated his martial arts to the limits.

While raising powerful defense, he also carried terrifying lethality.

However, against the siege of five Sword Demon Half-Demon Overlords, Yu Xiangtian only lasted for less than three minutes before he began to retreat.

“Hang in there!”

The Xu Nation’s Martial Sage, who had left the pit, gritted his teeth and shouted, “Old Tian, hang in there. I’ve already contacted the Liang and Kang Nations. Old Li and the others are rushing over at their fastest speed!”

“They won’t be able to hold on for long either!”

As Yu Xiangtian flew backward, he growled, “There are too many powerful demonic creatures. We’re not their match. We have to get someone in the Primordial Spirit realm to come here. Go contact Sword Sage Pei and the one overseas! If necessary, contact the Blade Sage of the Western Continent!”

“No.”

The Martial Sage of the Xu Nation blurted out.

As soon as he finished speaking, he rushed forward to attack a Sword Demon Half-Demon Overlord. While taking on some of Yu Xiangtian’s pressures, he quickly replied, “We can’t contact the Western Continent. There are also Demon’s Dens in the Western Continent. I reckon that they are also in a fierce battle over there. Most importantly, we can’t let the Barbarian Gods in the Boundless Mountain Range discover that we have been invaded by the demonic creatures. Otherwise, the barbarians won’t just watch and let go of such a good opportunity to invade!”

Barbarian Gods!

That’s right, there was also the threat in the Boundless Mountain Range.

At this thought, Yu Xiangtian’s expression turned solemn and his eyes were filled with anxiety.

The invasion of the demonic creatures was already drawing away their energy.

If the barbarians in the Boundless Mountain Range were to start a war now, one of the two fronts would collapse before long.

At that time, who knew how many people would die.

“Contact the one overseas! We must get him to come and help us. Also, try to contact White Emperor City. The situation this time is critical. We can’t sit still and wait for death. We have to contact all the Transcendent-grade experts we can contact and fight the danger together!”

Yu Xiangtian growled as he dodged the another attack.

“Pu! We’re already in midst of doing that!”

The Martial Sage of the Xu Nation grunted, his face flushed red.

Transcendent-grade experts were not limited to the Kingdom Defending Martial Sages of the various countries.

There were seven or eight independent Transcendent-grade martial artists like He Sanxiao in the Eastern Continent, or even more.

These people rarely appeared in the various countries. They were either on the subcontinent, overseas, or in the wilderness or the Dark North.

Yu Xiangtian and the other Kingdom Defending Martial Sages knew some of them and had heard of some others.

At this moment, no matter where they were, they were frantically contacting one another.

Because behind the Door of Darkness, there were not only powerful demonic creatures but also Ancient Demons!

The Ancient Demons were the biggest threat.

Little did they know that Su Jingxing had already dealt with the biggest threat.

…

In the Little Demon World.

Su Jingxing chased after the Half-Demon Overlords and killed most of them. He extracted 41 cards.

The remaining dozen or so escaped into the underground of the Demon’s Den in the Eastern Continent and were left alone.

Given the strength of the Martial Sages of the various countries, it was not difficult to deal with these dozen or so Half-Demon Overlords.

Su Jingxing had informed them of the situation in advance. As the Kingdom Defending Martial Sages, they would definitely go to the Demon’s Den in their jurisdiction to check.

Therefore, Su Jingxing was not worried about the threat at the three known Demon’s Dens.

Except for the fourth!

Through the Bone Demon’s memories, he saw that there were a total of four Doors of Darkness that connected the Little Demon World to the Eastern Continent.

In other words, there were indeed four Demon’s Dens as Su Jingxing had found out previously.

This fourth Demon’s Den was located…

In the Southern Wilderness!
