Zhang Yunxian stretched out his hand and pushed the heavy city gate, and a piercing chill came from the touch of his fingertips.

How long has this black stone been frozen, and how can this chill shake the mind of a saint?

He didn't dare to use his essence qi to ward off the cold, because he was afraid that something like what happened to Qing Ying just now would be injured by the inexplicable power contained in the black stone.

Flesh and blood alone couldn't push open the thick city gate, Zhang Yunxian just tried it and gave up decisively.

"I'll try again!" Xingzhen said, and the silver streamer covered his hands again.

Zhang Yunxian shook his head: "I know that your True Yuan power is also very damaged, don't be reckless!"

When Xing Zhen broke through the ice wall just now, although he only made twelve punches and was done, and he looked light, Zhang Yunxian still sensed the fluctuation of the True Yuan aura in his body very carefully.

Heishi's power for real people is still very powerful, and this has been fully confirmed on the way here, otherwise Bai Shiyou and Jiang Zongyuan would not be so easily surpassed by Zhang Yunxian and a few of them.

Therefore, when Xingzhen punched just now, he deliberately showed that unique sense of rhythm, not to make a fuss, but he had to ensure that the power of each punch was absorbed by the black stone, and there would be a certain residue on the ice, so how much force each punch should use, he had to calculate and make adjustments at any time.

In fact, if it was really just to break more than a meter thick ice cube, for Xing Zhen, it would be effortless at all, let alone him, even if he changed Fu Hui or Zhang Yunxian, he could easily do it.

Just now, it was only separated by an ice wall more than a meter thick, and Xingzhen's true yuan power had already been swallowed up a lot by the black stone, and at this moment, he was directly facing the city gate, if Xingzhen came again, Zhang Yunxian was very worried about whether he would be hit hard because of this.

And what they are about to face next may be the most dangerous situation in the secret realm, after all, now that things are clear, the benefit of everyone's hearts and minds on this trip must be hidden in the palace of the secret city in front of them.

No one is a three-year-old child, and he does not naively think that once he enters the palace, everything will be placed there and ready for others to harvest.

Traps, traps, and all sorts of hollow-out tests are sure to be readily available.

And at this time, if Xingzhen is hit hard, then Zhang Yunxian's side will lose his greatest support, and if they meet Bai Shiyou and Jiang Zongyuan, they will only have the fate of being wiped out.

Therefore, Zhang Yunxian will definitely not let Xingzhen take risks again.

"Don't waste your true yuan anymore, I should have a way to open this city gate!" he smiled and patted Xingzhen on the shoulder, "Put it away, look at me!"

Then, using his finger as a knife, he slashed lightly in the palm of his left hand, and the blood mixed with golden particles suddenly flowed down drippingly.

My evolved blood shouldn't be too bad, right?

Zhang Yunxian directly put his left hand slowly towards the black stone door.

The wound in the palm of his hand is actually very thin, and the speed of blood flow is not too fast, but the moment his blood stains the black stone, the whole palm suddenly emits a hot feeling, and the original cold and biting chill on the black stone city gate, seeing his blood, is like a mouse seeing a cat, they have retreated, like a low tide, where the blood flows, the chill will dissipate.

As Zhang Yunxian slowly moved his palm, his blood stains formed a perfect closure along the corners of the two city gates, that is, the shape was neither square nor round, and it looked a bit nondescript.

But this is not the point, at the moment when the blood stains intersect end to end, the color of red and gold suddenly shines brightly, emitting a dazzling brilliance, but the light only lasts for less than two seconds, and it suddenly turns into a raging flame.

The temperature of the flame was a bit terrifying, and even Zhang Yunxian himself was a little secretly surprised: "Is this really my blood?"

Xing Zhen and the others behind him were also dumbfounded, not understanding how Zhang Yunxian came up with this move, in fact, even Zhang Yunxian himself was in the clouds, he completely followed the voice in his heart that called him, and did all this.

The golden flame burned for about ten minutes before it gradually went out, and a scene that shocked everyone appeared!

I saw that on the blackstone city gate, in the area that had just been burned by the flames, there was a bright gap! About two fingers wide. In other words, the area that had just been surrounded by flames was completely separated from the city gates.

And through this gap, everyone finally saw clearly, the thickness of these two black stone gates was actually comparable to the ice just now, and it was more than a meter!

"The blood of the Apocalypse, how can it still have this function?" Qing Ying's eyes flashed with an inexplicable brilliance, and she didn't know what she was thinking in her heart.

Xingzhen stepped forward to check Zhang Yunxian's wound a little worried, and was relieved to find that the blood had coagulated and was fine.

"My lord consumes so much body blood, why don't you let me try it with the power of True Yuan!" he still couldn't help muttering.

Zhang Yunxian: "It's just a little blood, I used to go to blood when I was fine, it's not a big deal! We still have several real people and saints behind us, and now in this situation, it is difficult to distinguish between the enemy and us, so it is better to retain as much combat power as possible!"

Xing Zhen nodded: "Don't worry, my lord! If they dare to have any bad thoughts about you, I promise to make them regret entering the secret realm!"

Bai Shiyou and Jiang Zongyuan's existence, of course Xingzhen noticed it early on, he knew the details of these two people, like Hong Yuan, they were both Xia Di's subordinates.

If it weren't for the fact that in the frozen world, it was a little inconvenient to do it, he would have cooked these two of them together a long time ago.

As for the other saints, Xingzhen never looked at them.

Just kidding, is it okay that Lao Tzu is a real person who has lived for more than 5,000 years? As soon as the opportunity comes, Lao Tzu will be reborn as a celestial being! Is this mere sage who is several hundred years old worth my second glance?

Zhang Yunxian stretched out his hand again and pushed the stone that had been separated.

"Boom!" the stone fell, and an irregular gap was revealed in the gate, not too big, but more than enough for one person to enter.

"Let's go! After tossing for so long, I can finally go in and see the mystery!" Zhang Yunxian waved his hand to everyone easily.

"Your Excellency, please first!" Hoshijin said respectfully.

Zhang Yunxian was not polite, and took the lead in stepping in from the bottom of the gap with his legs.

Fu Hui supported Qing Ying, who was still a little weak, and followed Zhang Yunxian's figure to get in, and Xing Zhen was last.

"The shape of these palaces is really too historical! Under the beautiful appearance, there is no way to hide this ancient vicissitudes of temperament, if it is accidentally discovered by archaeologists from the outside world, it is estimated that their shocked eyes will fly out! This is really a real palace more than 5,000 years ago!" Zhang Yunxian stood in the city wall, looking up at the palaces in front of him that were completely shrouded in ice, without hiding his inner shock and admiration.

After all, he inevitably stood in the perspective of ordinary human beings to express such feelings.

However, Zhang Yunxian probably ignored one point, compared to this palace that has existed for more than 5,000 years, I am afraid that ordinary humans are more likely to be interested in Xingzhen, who has lived for more than 5,000 years, right?

After entering, Zhang Yunxian really counted the palaces in the city of the secret realm, which looked densely packed, no more, no less, exactly thirty-three.

Thirty-three, Zhang Yunxian didn't know whether the person who designed and built these palaces in the first place was unintentionally inserted willows and did it casually, or whether it was determined after deliberate calculations to determine the number of palaces.

You must know that in the minds of the vast majority of Chinese people, 'thirty-three' is a special number full of sacred and lofty temperament.

The most special thing is that in myths and legends, the supreme gods and goddesses reside in the thirty-three heavens.

These thirty-three palaces, I don't know if there is any special meaning?

These palaces are very tall, and the shortest ones are more than twice as tall as the city walls, which is the key reason why Xingzhen can see the architectural style of these palaces from the outside.

"There are thirty-three palaces here, let's go our separate ways!" Zhang Yunxian glanced at Xing Zhen and the three of them, "I suggest that you check it as quickly as possible, and see if those palaces can be easily accessed! If you don't know how to solve the problem, put it aside first, and then find a way to solve it later!"

Qing Ying naturally wished for this, although she had verbally promised that half of the benefits she got here could be given to Zhang Yunxian as a reward for bringing her to the Secret City, but what she said, how much, it was not up to her to decide? She could hide some of the benefits she had found and share the rest with Zhang Yunxian equally!

Therefore, she needs this opportunity to act alone, otherwise everyone will stay together, and what she has encountered and what benefits she has reaped, wouldn't it be clear at a glance?

"Yes!" she was the first to raise her hands in agreement, "then I'll go to the highest palaces in the northwest corner!"

Zhang Yun nodded indifferently: "Go ahead, if you encounter any danger, save your life first!"

"Don't worry, human!" Qing Ying trotted and couldn't wait to go to the highest palace in the northwest direction.

Fu Hui didn't say anything, turned around and strode in the opposite direction of Qing Ying.

Xing Zhen said that he was unwilling to act separately from Zhang Yunxian, and he had no intention of leaving: "It's just that if you investigate, the speed should be very fast, thirty-three palaces, we are divided into three ways, and the time is enough!"
