The place where the underground castle used to be was now blank and empty, as if it had been the case from beginning to end.

The underground castle is gone!

Seeing this scene, Zhou Su was slightly stunned, and then came back to his senses, thinking that it was because of the return of the demon princess and her subordinates, the exploration had been completed, and there was nothing worth nostalgic here, so they had no intention of staying for a long time again, and left here with the castle.

Although this sounds a little incredible, the fact is happening right in front of my eyes, and I can't help but believe it.

Although Zhou Su was a little puzzled, he quickly figured it out, although the formation in the underground castle Zhou Su looked through it, there was no such large teleportation array, but they could use it to build one outside, although that would cost a lot of resources, but this was not unacceptable for a demon princess who might take over the throne.

In the second layer of the demon defense, that is, the defense area of the 6th-order demon race, a figure flew up violently, galloping in the direction of Zhou Su, almost just a breath of time, and the figure came in front of Zhou Su.

It was a slender and strong male demon, with a protruding horn in the center of his forehead, holding a sharp long sword in his right hand, his eyes were cold, and he swung his sword towards Zhou Su, wanting to kill Zhou Su with a sword.

This is a 7th-order demon!

This demon clan was one of the dozen or so 7th-order demons that Zhou Su had seen in the depths of the underground before.

Although there is a verbal agreement between the human and demon clans that high-level monks are not allowed to make a move against a seventh-order monk, at some point, this agreement is a joke and has no effect at all!

In the face of absolute strength, any rules are useless!

At the same time, behind Zhou Su, there were also several 7th-order Terran monks who came to help, wanting to help Zhou Su block this blow and save Zhou Su, but their actions were so late after all, it was difficult to save Zhou Su under the surprise attack of this 7th-order demon.

But they can't, those 8th-order Terran monks can still do it, they came first, stopped in front of Zhou Su, took the blow for Zhou Su, and at the same time repelled the 7th-order demon who attacked.

Seeing this, Zhou Su stopped his defensive counter-attack, although Zhou Su's current strength was not enough to kill the 7th-order monk, but defeating the 7th-order demon clan, there was no problem in saving his life and escaping.

In the later stages of cultivation, the gap between each realm increases geometrically, and sometimes the gap between a small realm is like the gap between heaven and earth, which is enough to determine life and death.

Zhou Su's current realm can only be regarded as the middle stream, in this realm, you can skip the level, even if it is a small realm and fight, it is a genius, but it is almost impossible to cross a big realm!

The 6th-order cultivator is not enough to compare with the 7th-order cultivator in terms of magic quality and reserves, and the gap between the two is like a heaven and an earth, which is why only those above the 7th rank can be regarded as a grandmaster here.

The 8th-order elder of the Holy Demon Sect didn't go to look at the 7th-order demon clan, but turned his head to look at Zhou Su, with a kind smile on his face, and said with a smile: "You did a good job, go ahead and help! ”

"Thank you, Elders, for saving your life. Zhou Su bowed and said.

Although Zhou Su was able to ensure his safety, people always helped, and there was nothing wrong with saying thank you.

The elder smiled and nodded, "Go ahead." ”

After speaking, with a flick of his right hand, a soft magic power fluctuation pushed Zhou Su to leave this place, and they themselves flew towards the 6th-order demon living area.

Seeing this, Zhou Su knew that he couldn't get over there, so he simply continued to help those in need here and earn a little hard money, but his main attention was still on the situation between those elders and the 7th-order demon clan.

Zhou Su clearly knew that there was a 9th-order demon here, an 8th-order demon, and dozens of 7th-order demons before, and they didn't need those 7th- and 8th-order demons to make a move, just because the 9th-order demon showed his face, these 7th- and 8th-order Terran monks didn't dare to make a move, and even had to worry about whether the other party's 9th-order would do it.

However, now that those demons are still here, Zhou Su is not clear, after all, Zhou Su's current divine consciousness is not so far away.

The 8th-order Holy Demon Sect elder looked at the 7th-order Horned Demon in front of him, and asked with a kind smile, "What is the purpose of your coming here? Are you going to declare war on our human race?"

The male horned demon looked at the 8th-order human race in front of him, and did not panic at all, but the demon princess standing behind him was the demon princess, who was very likely to become the next demon king, he couldn't be stage frightened at this time, this horned demon also showed a smile, but compared to the elders of the Holy Demon Sect, it was a little ugly, he asked rhetorically: "What about your human race? Are you declaring war on our demon race?"

As he spoke, the horned demon also pointed to the Terrans and demons who were fighting together on the other side.

This 8th-order elder had long expected that this horned demon would not answer honestly, his eyes suddenly became cold, and he said in a stern tone: "Tell the people behind you to come out, otherwise..."

"Otherwise, kill me?" do you dare?" said the horned demon with a mocking face, although he felt the threat of death at this moment, but he didn't dare to take half a step back, he was a demon princess, and he believed that their princess would not watch him be killed by the Terrans, otherwise he would be slapping her in the face.

An eighth-order man from the Changling Empire next to him with a scar on his face looked at the Horned Demon with a fierce expression, and said fiercely, "Do you think I dare?"

As he spoke, this Scar 8th Order pressed a terrifying killing intent towards the Horn Demon, and at the same time took out his magic weapon and gestured in front of the Horned Demon, as if he would do it at any time.

The Horned Demon felt like he was falling into an ice cave at this moment, and he could feel that the scarred man was really going to do it, but he gritted his teeth and persevered.

If there is a betrayal of the royal family in the demon clan, then the royal family will even send the 9th order to kill it and exterminate the clan, so among the demons, they dare not rebel against the royal family, that is, looking for death!

This horned demon's face was extremely ugly at this time, but he still gritted his teeth and persevered, and said word by word: "Do you dare?"

"Hey, you're really not afraid of death? In that case, then I'll give you a ride!"

Seeing this, the Scar 8th Order General of this empire sighed lightly, looking quite surprised, but then he sneered, waved the magic weapon in his hand and killed the 7th-order horned demon.
