In the void, the three Demon Ancestors were moving forward at a rapid pace.

Suddenly, the fox flipped his hand and took out a small array plate, and then the light on it flashed, and a piece of animal skin appeared on the array plate.

The fox opened the animal skin and glanced at it, then accelerated to the side of the Demon Ancestor, and said, "The praying mantis has sent news that it has occupied five hundred cities of the human race, and I will ask you how to proceed next. ”

The figure of the Demon Ancestor slowly stopped, nodded with satisfaction, and said, "It's only been ten days since our army entered the Human Race, and they actually controlled five hundred cities, which is very fast. ”

The fox smiled slightly, "Old Ancestor's order, how dare they slack off." ”

"Inform them to stop the expansion for the time being, and first firmly grasp the five hundred cities. Demon Ancestor said.

The number of people they came to the Terrans this time was only more than 3,000 people, and they were divided equally among 500 cities, and there were only six or seven people in each city.

It was very difficult for such a small number of people to control a city, and if it weren't for the absolute superiority of the manpower they sent, they wouldn't have been able to do this.

"Do you need to bring in people from within the clan?" the fox suggested.

"Not for now. The Demon Ancestor shook his head, "The martial sect-level masters in the clan are all injured, and sending the martial king-level martial artists to come is not very useful, so let's leave it like this for the time being, and then let them come over when those martial sects in the clan have recovered from their injuries." ”

"Yes. The fox answered, took out a blank animal skin, and began to leave a message.

"Also, by the way, tell them that to control those cities, it is necessary to use high-pressure policies to make those Terrans completely lose the will to resist, and make them servile. If we can do this, even if we don't send people to watch over them in the future, they will not dare to resist, and the entire human race will become a slave of our race for generations. Demon Ancestor said.

"Yes. The fox nodded excitedly, and then teleported the hide.

"Let's go, keep going, I can feel that I'm getting closer and closer to that place. With a wave of his hand, the Demon Ancestor flew away.

......

......

Underworld, in front of the palace.

"Whoosh!"

Chu shocking figure flashed, bounced up violently, and stopped in front of the two huge gates, with a hint of excitement in his eyes.

Just now, there was a roar in his head, and he finally found a way to open the door.

His eyes were fixed on the center of the two gates, and his hands began to dance rapidly, and with his movements, intricate and mysterious runes flew out of his hands and were imprinted on the gates.

"Boom!"

The runes formed by the spiritual power fell on the gate, and there was a sound of metal clashing.

As the runes fell on the gate, the sound of metal clashing continued to sound, and the silent underground palace suddenly became noisy.

This sound lasted for eight hours.

"Boom!"

As the last voice fell, the huge underground palace regained its composure, and there was only a trace of aftersound, which still echoed in the distance.

Chu Jingtian wiped the sweat from his forehead, and slowly lowered his hands.

For eight hours in a row, he continued to punch out runes quickly, this is what he is, his spiritual power is extremely powerful, if he is someone else, even if he knows how to open this door, his spiritual power may not last so long.

"Boom!"

At the same time as Chu Jingtian put down his hands, the gate shook violently, and a huge roar was released.

Then, under Chu Jingtian's gaze, the gate slowly opened to both sides.

A moment later, the two gates, which were nearly fifteen meters wide together, completely opened, presenting the huge palace interior to Chu Jingtian's eyes.

Contrary to Chu Tiantian's expectations, when the door opened, what appeared in front of him was neither a hall nor a room, but a passageway.

The passage is the same width as the open gate, and is flanked on either side by cyan stone walls.

Chu Jingtian never imagined that after the gate of this huge palace was opened, there would be a passage inside, which was too far from what he imagined.

But as soon as he came back to his senses, he walked towards the gate.

In order to open this door, he spent more than ten days, and he didn't know how many difficulties were waiting for him later, so he had to hurry.

"Whew!"

Just as he stepped into the gate, there were a few soft sounds, and the passage became bright again.

Chu Jingtian's footsteps did not stop, and he continued to move forward.

"Boom!"

As soon as he stepped into the passage, the two huge doors that had taken him more than eight hours to open closed in an instant.

Chu Jingtian glanced back at the towering gate, then turned around and continued to move forward.

Since he can open it for the first time and a second time, it doesn't matter to him whether the door is closed or not.

This passage was fifteen meters wide and nearly twenty meters high, and the sides and the top of the head were all cyan stone walls, which made Chu Jingtian sure that this palace was definitely more than one floor, because just now, he saw that this palace was more than three hundred meters high.

And this also made him vaguely feel that this palace didn't seem to be very easy to break into.

Scanning the passage vigilantly, his pace slowed down slightly, although he was anxious, he also knew that safety was the first priority.

There was nothing to do all the way, and it wasn't until after walking along the passage for half an hour that Chu Jingtian's footsteps stopped again.

In front of him, two stone doors appeared again.

The stone doors were closed, cutting off his path, and if he wanted to keep going, he had to open them.

Chu Jingtian's brows couldn't help frowning, if this stone door was the same as the previous one, then if he wanted to open it, I was afraid it would take a lot of time.

But then, a smile appeared on his face, because he found that the runes on this second gate were so simple that he could easily open them.

Walking to the stone gate, he moved his hands, and runes flew out one by one, and he was about to open the stone door.

But just after hitting a few runes, his movements were slammed and stopped.

The rune of the palace gate was so difficult, but the rune of the second gate was so simple, he vaguely felt that there seemed to be something wrong with it.

With a movement in his heart, he stepped back a little, and more than ten meters away from the gate, he began to type runes again.

In this way, even if there is any danger behind the gate, he will have a time to react, and the safety factor will be greatly improved.

Chu Jingtian's movements were very fast, and in the blink of an eye, dozens of runes flew out of his hands and landed on the two gates.

"Huh!"

The moment the runes landed on the gates, the two gates made a soft sound, and they opened extremely quickly.

"Boom!"

Before Chu Jingtian could see the scene behind the two gates, behind the doors, a faint blue flame rushed out.

Chu Jingtian's face changed suddenly, and he immediately activated the fire essence in his body, and in his body, a purple-gold flame surged out, enveloping him entirely.

At the same time, the pale blue flame had completely surrounded him.

Fortunately, due to the barrier of the purple gold flame, the light blue flame could not cause him damage for the time being.

However, feeling the terrifying temperature of the light blue flame, Chu Jingtian couldn't help but feel a little happy in his heart, fortunately he had pushed some distance away just now, otherwise, he wouldn't have had time to react at all.

As soon as his footsteps moved, Chu Jingtian walked forward quickly, although the purple gold flame was emitted by the fire essence, but if he wanted to maintain it all the time, it was to consume his true yuan, and he had to get out of the range of the flame as soon as possible.

But after walking for two minutes, Chu Jingtian frowned and stopped.

The range of this light blue flame was not large, including five meters in front of him and five meters behind him, but he found that when he was advancing, the light blue flame that wrapped him was actually following him.

That is, whether he is moving forward or backward, he is always at the center of the flames.

If this continued, once the true yuan in his body was exhausted, then the capital flame would not be able to sustain, and he would definitely not be able to withstand the scorching of this light blue flame.

So, he had to get rid of the flames.

Looking at the light blue flames in front and back, Chu Jingtian sat directly on the ground, and the Heavenly Rank Fire Essence in his body slowly emerged from above his head, and then rushed into the light blue flame flames.

To deal with flames, it is naturally the most suitable fire spirit.

The fire essence is originally a heaven and earth spirit creature produced by absorbing the energy in the flame, as long as it absorbs the energy in the light blue flame, the light blue flame will naturally be extinguished.

After a moment, Chu Jingtian's brows furrowed again.

The fire spirit told him that the energy in this light blue flame was unusually huge, and if it wanted to absorb it all, it might take more than ten days.

With his current Martial Saint-level strength, the True Yuan in his body was completely able to hold on, but he felt that it was too long.

More than ten days had passed since he came to this underground world, and he didn't dare to imagine what the human race would look like now.

However, he had no other way than to use the fire spirit.

In desperation, despite the incomparable anxiety in his heart, Chu Jingtian still had no reason to explain that the fire spirit continued to absorb the energy of the light blue flame.

As for himself, he closed his eyes and began to cultivate.

However, it became more and more clear in his heart that he might not be able to leave this underground palace in a short period of time.

He had only just entered the underground palace not long before he encountered this flame, and behind him, he didn't know how many difficulties awaited him.

So gradually, Chu Jingtian was no longer anxious, but slowly calmed down.

As Ding Mengzhu and others said, he is the hope of the human race, and with him, the human race will have a chance to turn over, so he can't be in a hurry, because it is easy to make mistakes if he is in a hurry.

And the current situation does not allow him to make a single mistake.
