At first, because the coercion was only directed at Sandel alone, Nia didn't notice it. Therefore, when she saw Sandel fall to the ground, there was something strange in her heart.

However, when Xander said that the book of contracts had an aura similar to that of the tyrannosaurus king Bakar, Nia suddenly realized that the other party should be talking about Casillas in the Book of Contracts, and the two are both apostles, so the breath will naturally be somewhat similar.

And as a great apostle, he naturally does not allow an inferior race to sit on an equal footing with him.

"I said that I would get along with my contractual partners on an equal footing, but in the future, I won't even be able to contract on an equal footing?" The corners of her mouth twitched, and Nia always felt that her current setting was a bit pitiful.

What Nia didn't know was that in the outside world, even summoners who could only summon Casillas' clones were already rare, enough to be valued by major countries.

If it were known to the outside world that Nia had the ability to summon the apostles, then those nations would inevitably ...... Get rid of Nia before she grows.

This is already a force beyond their control, and since they can't take it into their hands, they can only destroy it in advance.

——————

"Get up." Nia said to Sandel in front of her.

However, the other party still knelt there motionless. It can be seen that even though he was forced to sign a slave contract because of his offence against the apostles, Sandel was not convinced by this result.

Nia sighed in her heart: sure enough, subduing the black knight who had followed Bakar was not as smooth as she imagined.

Walking up to the Black Knight, because of the other party's height, Nia was a little shorter than the opponent who knelt on one knee even if she was standing.

Lowering her voice, Nia said to Sandel, "Don't worry, even if you sign a slave contract, I will definitely not treat you as a slave in the future." ”

However, Nia's words didn't make Sandel feel any way.

Ignoring the unmoved Sandel, Nia raised her right hand above her head and solemnly swore an oath: "Swear by the god of magic, if you treat Sandel as a slave in the future, you will be abandoned by magic." ”

A mysterious feeling welled up in her heart, and Nia knew that the oath had been successful.

Hearing Nia's words, Xander's body visibly shook.

This is not an oath that can be rewritten casually, once it is made, it is valid for life. For a magician, not being able to use magic is even more terrifying than simply killing it.

The other party is clearly serious. Thinking of this, Sundel, who was dissatisfied with Nia because he was forced to sign a slave contract, finally untied the knot in his heart a little. Because after Nia swore an oath, the relationship between the two has actually become a somewhat alternative master-slave relationship.

It seems that he has a good master.

If it was replaced by those profit-hungry adventurers, Sandel really didn't dare to imagine what he would become of a former sixth-order powerhouse.

"Got it, master." Thinking of this, Xander stood up obediently, then walked behind Nia and stood still.

"At this point, the matter of the Dark Corridor is over." Whispering, Nia began to look around. Now that I've finally got through here, it's natural to find out if there is any loot.

Sadly, Nia looked around and didn't find anything worth taking. Finally, she fixed her gaze on the place where the Celestial Destroyer had been defeated, where an exquisitely crafted lightsaber lay silently.

On the continent of Arad, lightsabers are extremely rare, and most of them are collected by nobles. Therefore, this lightsaber will definitely be able to sell for a good price even if Nia herself does not use it.

Just as Nia was about to bend down to pick it up, Xander's voice came from behind her, "Master, can you leave this lightsaber here?" ”

"It's a weapon that Rogier has used for most of his life, and I hope this weapon can be by his side." Even if the contract has been signed, it is still necessary to think about the deceased partner, and it can be seen that the relationship between Sandel and Rogier is not as normal as it seems.

Now Nia is faced with a choice between a lightsaber or Xander's loyalty. Without hesitation, Nia picked up the lightsaber on the ground, and even the fragments of the armor of the Celestial Destroyers scattered around her.

Seeing Nia like this, Sandel couldn't help but have a good impression of Nia.

But in the next moment, he let him know how wrong his previous thoughts were.

I saw that Nia didn't stay where she was after picking up the lightsaber, but turned around and walked back, lifting the item she had just picked up in front of him.

In a sincere voice, Nia said, "Since it's your friend's weapon, of course I won't take it. But staying here will sooner or later be discovered by the adventurers, and we should hide it in a safe place. ”

Subconsciously reached out and took it, and Sundell was still a little stunned until now.

But the weight in his hand made him react, and after a deep look at Nia, Xander put down his weapon, cherished what the Celestial Destroyer had left behind, and walked towards an extremely hidden corner of the dark corridor.

It didn't take long for Xander to walk back empty-handed.

There was nothing left in the dark corridor for Nia to stay, so she led Sandel to the final castle lord's palace.

At the entrance of the palace is a gate with a height of more than ten meters, and the dark blue color makes this gate look more simple and heavy.

"Let your subordinates open this door for you." As soon as he reached the door, Sandel took the initiative to ask.

It hadn't been opened in a long time, and the door creaked with Sundel's hard push.

As the door gradually opened, Nia became more and more nervous. The previous Heavenly Destroyers were already so difficult to deal with, and if Freya had been here, she would not have been able to compete with the more powerful City Lord of Light.

As the gate was completely opened, a straight walkway appeared in front of you, which was only a few tens of meters, leading to a field with a radius of about 30 meters. In the middle of the field, there stood a man covered in electric light. This is none other than the last lord of the Sky City, the Lord of Light, Seghardt

However, after Nia entered the door, she only glanced at the Lord of Light, and her eyes began to roam around the square.

On the ground, there were some skeletons, but seeing this, Nia was relieved.

If Freya had been here, she would have at least left a corpse behind. But there are no traces of the scene, which is enough to prove that Freya did not appear here.

"Outsider, are you also going to the Heavenly Realm?" A deep voice came from the mouth of the Lord of Light.

"No, my friend's teleportation circle that strayed into the first layer disappeared some time ago, and I'm here to look for her."

"No one has been here in hundreds of years, and your friends haven't been here. I've heard of the teleportation array, and it doesn't lead to the back. If you don't have anything else to do, get out of the way. Hearing that Nia didn't mean anything from the past, Saidhart responded calmly.

"Let's go, and help close the door by the way." Getting the news, Nia beckoned to Sandel Dao.

"Master, aren't we going to fight?"

"Nonsense, I'm here to find someone, not to fight. Since the person is not here, let's go down and look for it. ”

As the door closed, Seidhart saw the black figure following Nia.

"Sandel, have you betrayed Lord Bakar? Don't...... The people who are still guarding the Sky Tower...... Is it just me......"
