Xuanwu Palace.

The palace is located in the middle of a large lake, and the whole palace is suspended above the water, which is very magical.

At this moment, on the square in front of the palace in front of the Xuanwu Palace, a figure appeared on the edge of the square quickly on the water.

The entire immortal tomb has set up a forbidden sky array, even if the immortal who returns to the void land comes here, he has to obediently walk on the ground with his feet. Want to fly in the air like you do outside, unless you're a Celestial Immortal.

As soon as he stepped on the square, Qin Hao also breathed a sigh of relief.

Seeing that there was no one left and right, he ripped off the tattered pants on his body and took out a new one from the Nine Tribulations space and put it on.

In the lake at my feet, I don't know how there is a large school of piranhas, these piranhas alone are not a cause for concern, but as long as there are many of them, they are also a scourge.

And for Qin Hao, these piranhas couldn't break his skin at all, but even so, his pants were still damaged.

'Smack~'

A piranha who stepped on the torn pants and didn't let go, swept his feet, and the torn pants flew out and fell into the lake.

The next moment, the entire lake rolled up, and a large group of piranhas, which smelled fishy, frantically swarmed up.

Qin Hao glanced at it and shook his head with a smile.

But this piranha even eats the corpses of its own kind, it's...

Turning around, too lazy to take another look, Qin Hao turned his gaze to the square in front of him.

The square in front of the Xuanwu Palace is no different from the White Tiger Palace in scale, the only difference is that the White Tiger Palace is dilapidated, while the Xuanwu Palace in front of you is completely free of the slightest trace of dilapidation.

Walking through the square in front of the hall, Qin Hao's eyes paused on the Xuanwu statue in front of the stairs, and then walked up the stairs.

There are 288 stairs, and when you look down from above, you can see the entire square in front of the temple.

Qin Hao's footsteps paused in front of the main hall of Xuanwu Palace, and when he looked in from the outside, all he could see was the splendid arrangement. After observing for a moment, Qin Hao raised his legs and stepped into the main hall.

'Woo~'

In my ears, there seemed to be a cold wind blowing.

Qin Hao looked left and right, and couldn't help frowning slightly.

The temperature in this hall was at least thirty or forty degrees lower than outside, but just standing in front of the hall door, he couldn't feel the temperature difference in this hall at all, which was really incredible.

This low temperature is nothing, let alone dozens of degrees below zero, even if it is hundreds of degrees below zero, he will not care, what Qin Hao is really curious about is how the difference between inside and outside is caused, and it is so clearly divided.

After standing still for a while, Qin Hao couldn't think of a reason.

Looking around, the layout of the entire hall is very simple, and it is almost unobstructed at a glance.

In the empty hall, after Qin Hao's gaze swept away, he finally locked on a door on the left side of the depths of the hall.

After a while, Qin Hao came to this door, and his footsteps stopped.

Stretching out his hand, he gently pushed the door, which he thought should be difficult to open, but it was so easy to open.

The look of surprise on Qin Hao's face flashed.

As soon as the door opened, a cold air gushed out from inside the door.

Qin Hao, who was standing at the door, shuddered.

"It's so low!" Qin Hao said in surprise.

The temperature in this hall just now is low enough, at least minus 30 degrees Celsius, if an ordinary person does not wear professional warm clothes, I am afraid that he will not be able to live long at such a low temperature. Even if it is an innate being, it will move a little slower than usual at such a temperature, and only when it has reached the realm of a Purple Mansion Cultivator will it be completely unaffected.

But the temperature behind the door in front of him was more than ten times lower than that in the main hall.

On Earth, the lowest known temperature of mankind, the so-called absolute zero, is -273.15 degrees, at which the molecules of any matter will lose kinetic energy, and this temperature is impossible to reach under the knowledge of mankind.

But... That's on Earth!

This is not the Earth in front of you, let alone the universe in which the Earth is located.

It's like the temperature behind the door in front of Qin Hao's eyes, which definitely exceeds minus 300 degrees, which is a temperature that is completely impossible to appear on the earth, and it is also a temperature that cannot be understood by the humans on the earth at all.

But it appeared so naturally, and Qin Hao, a living person, stood in front of this low-temperature air current, without any discomfort.

It can be seen with the naked eye that below the epidermis of Qin Hao's body, an orange-red energy is slowly flowing.

Heat!

This is the ability that Qin Hao's flame control has gained after entering the ninth order.

Under normal circumstances, Qin Hao will also be slow to move, and even difficult to move at such a low temperature, after all, it is more than 300 degrees below zero, even in this world, such a temperature is extremely rare.

With a strength like Qin Hao, he also had to cast the temperature of internal heat to counter the low temperature of the outside world.

In this way, he is no longer affected by the low temperature outside.

There is nothing to hesitate about, there is no other passage in this hall except for such a door, and the low temperature in front of him can't help Qin Hao at all.

Step behind the door, an ice-blue passageway.

At the end of the passage is a dark blue double door, and the entire passage is about a kilometer long.

Walking into the passage, there was a sound of 'bang~' behind him.

Looking back, the door was closed.

Qin Hao even turned around and tried to open it, but found that the door that was originally easy to push open outside couldn't be opened here.

Helpless, Qin Hao had no choice but to give up and continue to do useless work, and instead walked towards another door at the end of the passage.

He walked very carefully, and in such an unfamiliar environment, unknown dangers could arise at any time and place. Especially the special environment in front of him, Qin Hao was not sure what would happen later.

Slowly moving forward, the temperature around me continued to decrease as the dark blue gate became more and more visible.

From more than minus 300 degrees at the beginning, when I walked half the distance of the entire passage, the temperature around me was already low to a terrifying level of nearly minus 500 degrees.

When he arrived here, even if Qin Hao had internal heat support, he felt a certain sense of sluggishness in his body at this moment.

Looking up at the door that was still five hundred meters away, Qin Hao's brows furrowed.

"The temperature here, I'm afraid ordinary people in Vientiane have to be discouraged." muttered in his heart, but the steps under his feet still walked forward steadily.

Five hundred meters, if it rests elsewhere, it is only a few breaths. But when he got here, Qin Hao walked for more than ten minutes, and only then did he walk more than two hundred meters away.

When he arrived here, the temperature around him had dropped to more than minus six hundred degrees, and Qin Hao could clearly feel that his body was beginning to harden, an ordinary simple action, but it would take hundreds of thousands of times more force to do here.
