At the same moment when he saw the crystal palace cloaked in ice, Zhang Yunxian also sensed the aura of Xiaoqing and several other sage protectors of the Moon Worship Sect.

The location of the few of them happened to be on the other side of the Crystal Palace, that is to say, it was exactly opposite to the direction in which Zhang Yunxian and the others came.

Zhang Yunxian roughly estimated that the distance between the few of them and the Crystal Palace was about a hundred kilometers, that is, they were not much different from Yun Yizhen behind him.

It also means that the speed of Zhang Yunxian and the four of them is at least one day ahead of them.

"Is this where the Secret Realm Center is?" The impatience on Qing Ying's face swept away, and her eyes looked at the crystal clear palace complex in front of her with bright eyes.

Xing Zhen was silent as always, but the thoughtful look in his eyes made Zhang Yunxian wonder if he had any unforgettable past with the owner of this secret realm.

Fu Hui was completely indifferent to all of this in front of her, as if she wasn't very interested in anything other than human clothes.

Zhang Yun felt that the closer he got to these palaces in the center of the secret realm, the more he felt a strange feeling of being called and looking forward to it in the depths of his heart.

"Xingzhen, do you see something?"

"Huh?" Xing Zhen suddenly woke up from his contemplation, and shook his head at Zhang Yunxian with a little embarrassment: "My lord, I just see that the style of these palaces is a little familiar for a long time, and in some local details, there are some similarities with the style of the dynasty I lived in as a child!"

Zhang Yunxian: "It's not strange, you were born five thousand years ago, aren't you, and the time that this secret realm has existed for almost so many years, in terms of time, the lifespan of these buildings is comparable to yours, and it may be even longer than you exist!"

When Qing Ying heard Zhang Yunxian say this, the shock in her eyes was even more exaggerated than when she saw the palace group just now: "You...... What did you just say? This human ...... How many years has he lived? 5,000 years? You two aren't singing here, are you?"

Xing Zhen glanced at her lightly: "Are the bereaved clans so unruly today? Thousands of years ago, with the attitude you just spoke, the Lord of the Apocalypse could make you pay with your life!"

Qingying: "...... Our merman remnants have nothing to do with the Apocalypse!"

Xing Zhen: "The Eight Great Remnants are all servants of the Apocalypse!"

Qingying: "I'll believe what you say?"

Xing Zhen: "Go back and look through the previous records of the seventh generation patriarch of your clan, and take a good look at how they used to respect adults!"

"Seventh generation ago?" Qing Ying replied after a moment's thought: "Even I don't know how many generations our current patriarch's inheritance belongs to, the history of our clan, I don't know how many times we have suffered inexplicable generational breaks, you told me to let me go back and read the family rules before the seventh generation patriarch?"

Xingzhen sighed slightly: "Alas...... It's pathetic!"

Zhang Yunxian hurriedly waved his hand and stopped Qing Ying, who was about to go crazy again: "Miss Qingying, you don't need to be angry, what I just said, there is no false element in it, Xing Zhen is a member of the Divine Envoy Remnant Clan, and belongs to the same Eight Great Remnant Clan as you, I believe that each of your clans has a corresponding method for identifying the age of members, and after going out from the secret realm, we can visit your Shark Clan alone, you can rest assured that the identification is!"

After a pause, he continued: "There is no point in discussing these controversies at all, we should work together and find a way to enter these palaces, isn't it?"

Qing Ying wanted to speak and stopped, and finally only nodded: "You are right! In fact, I have also seen along the way, the strength of several of you is far better than I don't know how many times, I can come here this time, it is completely to take advantage of you, if I can enter this secret city, all my gains, I can give half of it as a thank you for it!"

"It's too early to say this, how to get in is a problem now!" Zhang Yun shook his head meaninglessly.

The four of them walked forward as they spoke, and after three hours, they had completely walked under the rammed wall of more than five meters high in the outermost part of the palace complex.

"I didn't expect that there is an air ban in this area, otherwise it would be easier for us to jump in directly!" Qingying said depressedly.

"It's just more than a meter thick of freezing, it's not a trouble!" Zhang Yunxian looked at Fu Hui: "Miss Fu Hui, it's time for you to contribute!"

Fu Hui didn't say a word, raised two white little fists, and smashed them directly on the layer of bright ice outside the city gate.

"Bang!"

"Bang!"

“……”

After a few deafening fist sounds, Fu Hui's expression, which had been painless, suddenly widened in horror as if she had seen a ghost, and she couldn't believe what she was seeing.

"It's useless! it's too hard!" she muttered.

Zhang Yunxian and Xing Zhen exchanged glances.

It's not that simple!

Such thoughts invariably came to their minds.

"Get out of the way! I'll try!" Xingzhen patted Fu Hui lightly on the shoulder, motioning for her to take a few steps back.

"Oh...... Here you go!" Fu Hui's mood was a little low, and she walked to the side.

Zhang Yunxian had the heart to comfort her, but Xingzhen had already begun to attack, so he had to turn his attention to the city gate again.

When Xing Zhen made a move, his fists were covered with a layer of mercury-like streamers, and Zhang Yunxian knew that it was the embodiment of Zhenyuan.

If the fierce attack of Fu Hui just now gave Zhang Yunxian the feeling of being like a savage hammer, fierce and mighty, then the effect of Xingzhen's double fists hitting the surface of the ice wall at this moment was like a dough being thrown on the board!

"Poof!"

"Poof!"

Compared to the deafening just now, the sound of Xingzhen's fists was obviously low and soft, and his shot was also slow, after each punch, it seemed that he had to think for two seconds to know where to hit the next punch.

"Poof!"

"Poof!"

“……”

Xingzhen only threw twelve punches from beginning to end, but it took almost a minute.

"Okay, now I believe it, this is really an old man who has lived for five thousand years, and this set of punches just now is a compulsory course for your old man's daily morning exercises, right? I have to say, when it comes to the nature of the performance, it is still very pleasing to the eye......" Qing Ying glanced at the ice wall that was still intact, and suddenly couldn't hold back her laughter anymore.

Xing Zhen still glanced at her lightly, as if he was not even willing to waste the strength to defend himself, and turned his head and nodded lightly at Zhang Yunxian twice.

"Click!"

A crisp sound suddenly sounded, and Qing Ying couldn't stop laughing halfway through laughter, because the sound of shattering came from the ice wall in front of them.

The sound was accompanied by a thumb-thick crack in the center of the ice.

As soon as the crack appeared, it was as if the dominoes had suddenly collapsed, and then a series of bursting reactions occurred, in Qing Ying's words, quite pleasing to the eye.

The cracks in the ice, like the structure of a spider's web, spread rapidly from the center point to all sides.

"Click......"

The sound of cracking sounded one after another, and after a few seconds, the entire ice covering the outside of the city gate, from the inside out, completely showed signs of dense cracks.

Xing Zhen made a 'please' gesture to Zhang Yunxian.

Zhang Yun nodded in understanding, strode forward, stretched out only one index finger, and gently poked it outside the ice.

"Boom!"

In an instant, the cracked ice wall just now was shattered and only a piece of debris remained, and the two quaint and heavy black stone gates were completely presented in front of the eyes of several people.

"It's this kind of black stone again?" Zhang Yunxian couldn't help but sneer in his heart.

That's right, these two closed gates were made of the black reef at the bottom of the entire ice sea.

It's no wonder that Fu Hui, the giant remnant of the city that has always had the 'Mighty Titan', smashed the ice bucket so hard and didn't play any role, it turned out that it wasn't that her strength was not enough, but the power she sent out was all absorbed by these two blackstone gates more than three meters high!

The moment he saw the Black Stone City Gate, the strange feeling of being summoned in Zhang Yunxian's heart was suddenly extremely strong, and even his heartbeat was much sharper uncontrollably.

"Ahh......h

Fu Hui took her in his arms, "It's not good! attack!" she exclaimed nervously.

Zhang Yunxian stepped forward to inspect it, and explained with some regret: "No one attacked her! It was she who just wanted to spy on the situation behind the city gate, but she was injured by the city gate!"

Qingying tried hard to raise her arms and grabbed Zhang Yunxian's sleeve with all her strength: "Help me...... Human!"

Listening to her angry voice, you know that she was really injured just now.

Zhang Yunxian patted the back of her hand: "Don't worry, the damage to the spiritual platform will not be fatal, but your spiritual power cultivation will definitely not be able to recover to its peak state in the short term, which is unfortunate, because there is no excess spiritual power in my body to give you now!"

When Qing Ying heard this, the remorse on her face was overflowing, blaming her for being too anxious just now, and she didn't control it for a while, so she had to use her spiritual sense to spy on the situation in this city wall, but now it's okay, most of her spiritual power has been destroyed in the blink of an eye!

Xing Zhen glanced at her expressionlessly, and although he didn't say anything, Qing Ying still read a hint of sarcasm in his eyes.

"Concentrate your spiritual power, guard your spiritual platform, and don't let this black stone detect your spiritual power fluctuations!" Zhang Yunxian finally explained, and then he motioned to Fu Hui to take care of Qingying carefully, while he returned to the front of the Black Stone City Gate again.

"Perhaps, I can open it?" he felt the increasingly strong call in his heart, and the scene in his mind that day was in the altar of light, and he used his blood to travel into the black altar......
