The thirteen cities of the Fringe were supposed to be heavily guarded.

However, even after a hundred turns, they were still unable to see a single soul on the two streets, and the houses around them were even more orderly, with even the words on the signboard neatly arranged in an orderly manner. There seemed to be no houses here, only soldiers living in this place, and on the other side, one could still see some sandbags and weapons, and on the other side, there were not many small houses, but they stretched out in all directions, and in the middle of the city, there was an octagonal shaped high platform, which looked like a place for fighting.

"I've only read from the military manual that these nine cities were done quite neatly. Looking at them now, it is truly a sight to behold. Such a city is truly a sight to behold." Gu Danyan was also sitting in front of the carriage along with Eunuch Wu. His legs dangled off to the side as he lightly swayed. His eyes occasionally glanced towards Duan Cheng Xuan with a hint of novelty in them. It seemed like these words came from the bottom of his heart.

Duan Chengxuan could only sigh that if this was the case, he would be able to make Gu Meiyan happy. Previously, he might as well take off this burden and travel the entire world with her.

"There aren't many books that can introduce the borders of Thirteen Cities. Since Your Highness can see them, then it would be more like reading a wide variety of books." Eunuch Wu's eyes narrowed into slits as he hurriedly flattered.

Gu Liuyan only said that Eunuch Wu had good eyes, he really did seem like a sightseer.

However, Gu Liuyan became more and more curious as to who taught them how to build this eight trigram city.

There was nothing special about this place, not to mention the fact that there were only Yin and Yang, the sun and the moon, and so on, but there were still some differences between the eight elements. After all, this was a very important military location, so wouldn't it mean that as long as someone knew the appearance of the Eight Trigrams Formation, they would know the layout of it, and they wouldn't even need a defensive map?

He was much younger than Duan Chenrui and Duan Chengxuan. At first glance, he looked like a kid, and even Gu Liuyan was a few years older than him. At this moment, looking at the arrogance on his face, he felt that Duan Feng was more of an arrogant kid, and didn't treat him as a prince with strength.

"Long time no see, Princess Palace …"

"Just call me by my name. I only call myself princess when I want to be the first one to challenge someone else." Gu Danyan jumped off the carriage. The pain from her neck reminded her of what her eyes were doing, but she unconsciously touched her neck and moved her body. She then looked up at Duan Feng and asked: "What did you call me here for?"

"Duan Chengrui controls everything I have, and he only trapped me within this empty city." The arrogance on Duan Feng's face vanished, leaving behind only regret and unwillingness. "He's borrowing my hand to get you back."

"Third nephew is really anxious. Since he wants me to return, then why did he call Duan Cheng Xuan over earlier?" He should know what intentions Duan Chengxuan has towards me, so he naturally won't let go so easily. Did you want him to come to this empty city to kill him, or did Duan Chengrui want him to kill him? "

He slowly walked up the steps and stood in front of Duan Feng, one step at a time. Those peach blossom eyes now revealed the cunning of a fox, and that slender jade hand was now holding onto the saber blade as it lightly pressed against Duan Feng's neck: "Traitorous prince, he was once connected to Gu Cheng. Even if I were to kill you here, I believe that Duan Chengrui's people wouldn't care."

As he said this, Gu Daiyan's gaze fell on the people on his left and right.

The paralyzed man stood on her left hand side, while Eunuch Wu, having changed his previously feminine face, stood on her right.

"His Highness can do whatever you need, even if it's the ninth prince's life." Eunuch Wu bowed respectfully towards Gu Liuyan, while the paralyzed man beside him had even drawn his sabre.

Duan Chengxuan was still far away when he noticed the strange expression on Gu Daiyan's face.

In the next moment, Gu Danyan had already retrieved the Cirrus in his hand and coldly looked at Duan Feng: "No need to kill anyone, I only need to bring my servants and Mu Qing back."

He specifically bit down on the two words' Mu Qing 'a little heavily.

However, Duan Feng grabbed her wrist first. "If you don't follow them back, then my life will be over."

He didn't shake off Duan Feng's hand, but instead carefully observed the expression on his face. Just as she was about to say something, two figures that shouldn't have appeared in this place appeared behind Duan Feng's back. Gu Danyan's expression changed, but he couldn't say a word; he could only look at Duan Feng in shock: "You …"

"You have to go back, I don't want to lose my life!" As Duan Feng said this, she pulled her back. "As long as Duan Chengrui obtains you, I'll be able to retreat safely."

Gu Danyan opened his mouth slightly, but the two men in the yard had cold sabers on their necks.

She felt cold all over, the warm blood seemed to have frozen over, and only a buzzing sound could be heard in her head as she bit her lips. She still pretended to be calm as she looked at Duan Feng: "Get my subordinates and Mu Qing to go back."

"But you didn't bring Duan Cheng Xuan, I still want to …" Duan Feng said excitedly.

Eunuch Wu's dagger had already been pressed against Duan Feng's neck. "Ninth Prince, you've gone too far. His Highness has already reached an agreement with the Third Prince regarding the matter regarding the King Jing, and this Mu Qing is someone His Highness has pointed out. How could he give up so easily? It's up to these four servants to go back."

"Mmm, let them go back to report. Otherwise, once Duan Chengxuan arrives, we won't be able to enjoy ourselves properly."

Gu Liuyan didn't even know how she managed to say this with a smile on her face.

Even Duan Chengxuan didn't notice anything amiss, so he could only do something extremely extreme. So it turned out that Duan Chengxuan had called him over to be Duan Feng, but now that he saw Duan Feng being threatened, he could be slightly more at ease.

Rather than implicating Gu Tinyan in the internal strife, it was better to go back to the Fallen Water Pass and settle the matter of immortality.

However, Duan Chengxuan instead felt that this empty city was extremely strange.

Gu Daiyan, on the other hand, glanced at Duan Chengxuan before turning around to look behind Duan Feng. The rooms that were supposed to be empty were empty, but they were filled with traps. The crossbow bolts that were as thick as an arm were already loaded.

If the other empty cities were like this as well, then Duan Chengxuan and them …

He didn't dare to think too much and could only pretend to be calm as he looked at Duan Feng: "You win."

Her unfathomable words caused Duan Feng to reveal an expression of bewilderment, but Gu Pingyan helplessly said to Duan Chengxuan, "You guys go back and report to Duan Chengxuan, I'll be leaving in a few days."

Duan Feng's expression changed slightly, but in the end, she did not say a word. She only ordered her men to bring her four servants back along the same path as before and did not take any action.

When he saw Duan Chengxuan leave his hands, the brat behind her, who was supposed to be still wet behind the ears, lightly embraced her from behind, and said with a low smile, "You're really smart. I thought I was going to threaten you a little more …"

"I didn't expect that the person who had hidden the deepest would be you." Gu Liuyan did not dare to break free from this disgusting embrace, only lowering his head in grief.

Even if she had miscalculated, she should still admit her defeat.
