After entering the hole, Cao Yu and Lan Qiji saw snow all over the place, which was a wonder in the underground space.

At the same time, the temperature also dropped a lot, Cao Yu felt the cold feeling for the first time since he cultivated, although he frantically agitated his true yuan to form a protective shield outside, but it still couldn't stop the cold qi from pouring into his body.

There was another thing that made him even more jaw-dropping, in this, he felt that the formation speed was much slower, and turned to Lan Qiji and asked:

"Lannu, can you sense the weirdness of this place?"

didn't explicitly say that it affected the speed, Cao Yu just looked at what Lan Qiji said, after all, he was a Martial Emperor-level powerhouse, and his sense and perception must be stronger!

"It makes no difference to me!"

Lan Qiji said indifferently.

Hearing this, Cao Yu almost vomited a mouthful of blood, it seems that this Martial Emperor-level powerhouse is really not covered, he is already trembling, and others are still like no one.

At this time, Lan Qiji noticed Cao Yu's strange appearance, his face was pale, and his whole body trembled slightly, and immediately the true yuan in his hand opened, and a blue protective shield was formed, but after this protective shield was formed, Cao Yu instantly felt that he was surrounded by a warmth, and couldn't help but breathe a long sigh of relief.

"Please also ask Cao Shao to punish him, it's the criminal slave who is not thoughtful!"

Lan Qiji first protected Cao Yu before confessing his guilt.

"That's it, that's it, I'm not as good as others, there's nothing to blame!"

Cao Yu didn't lose his temper, although from what Lan Qiji did before, it was not enough to kill him ten thousand times, but now as his own slave, there is no need to be like this, in the final analysis, they are all his own subordinates, although even if he abuses Lan Qiji madly, Lan Qiji does not dare to be disrespectful, but it is too inhumane to do so!

This is not in keeping with the cultural and moral qualities he received in his previous life.

"Thank you Cao Shao!"

Lan Qiji thanked him gratefully.

After thinking for a while, he continued: "Cao Shao, what you just asked is indeed a little strange, the temperature here is obviously lower, and my ability to move will also slow down! It should be that there is a strong domain in this space, and the effect of the domain may be formed through these snowflakes!"

As he spoke, his hand touched a snowflake.

Sure enough, but when you touch those snowflakes, you are affected even more!

"There's got to be a cat in there!"

The so-called abnormal things must have demons, this is the unchanging truth.

The two of them landed gently, the upper and lower layers of space are very weird, and there is no support at all, which is no longer in line with the laws of nature!

Cao Yu's face was a little solemn, he didn't expect that there would be such a unique world in this city lord's mansion.

Steward Yun didn't speak, there are indeed bookshelves here, and there are not a few of them, not much better than the previous layer.

"Cao Shao, do you continue to study?"

Lan Qiji still remembered the purpose of Cao Yu's coming down, so he asked as soon as possible.

"Of course! nothing is more important than reading!"

Cao Yu looks like a good child, and he forgets to sleep and eat when he reads.

As far as the eye can see, almost all the bookshelves here are covered with snow, but this does not affect Cao Yu's reading, he doesn't need to open those books, as long as his soul sweeps, all the books will be absorbed by him!

"Okay, I'll wait for you here!"

Lan Qiji nodded, for him, whatever Cao Yu said was what he said, as for whether there were other treasures, it didn't matter!

As long as Cao Yu says he wants to do it, then he has to work hard.

In the already dim underground space, thick snow covered the ground, although Cao Yu's speed was affected a little, it was not a big problem, and he quickly flowed in front of the various bookshelves.

In the passage of each bookshelf, leave a trace.

Soon, Steward Yun also fell, and he didn't feel so good at this time!

The bone-chilling cold made him tremble all over, and he said in a trembling voice, "This... My lord, he really loves to read! He doesn't forget to read even when it's cold."

Lan Qiji smiled indifferently: "Hehe, Cao Shaonai is a peerless genius, and at the same time, he is also very humble, and he is full of love for learning all the time!"

These words were obviously sycophants, but Steward Yun still nodded and expressed his deep agreement.

Half an hour passed, Cao Yu finished reading the books on this layer again, although the involvement may be more profound, but there is no substantive gain for Cao Yu.

For him, the most useful at the moment.

Either it is any cultivation experience of Emperor Wu or the corresponding information, as long as it is Emperor Wu's, it will be more useful to him.

Either it's a martial saint or something below, but it requires innovative ideas and experience.

Again, the relevant alchemy experience of an emperor-level alchemist!

Or the ancient mysticism.

But to his disappointment, this information was not collected.

"How's it going? Cao Shao, how is the harvest!"

Lan Qiji asked.

Cao Yu shook his head slightly and didn't say anything.

"Old man, where are the martial arts and exercises here!"

He looked around a long way just now, but he didn't find the so-called martial arts and exercises, and looked at Steward Yun with some doubts.

Being questioned like this, Steward Yun was excited, and his body that was about to be frozen poured into a stream of heat.

There was a hint of excitement in his eyes.

"Lord Hui, the previous city lord hid those martial arts and exercises under a frozen lake!"

"Frozen lake, where does this ice lake come from!"

Cao Yu was going to be blindfolded when he heard it, why did this underground space still have a frozen lake.

Some looked at the cloud butler in disbelief.

Steward Yun also knew that what he said was a little unrealistic, so he forcibly shook off the snowflakes on his body, raised his arms tremblingly, and pointed towards one place.

"Are you sure?"

From the direction pointed by Steward Yun, Cao Yu had looked for it there just now, but he didn't see the so-called ice lake.

"I followed the previous city lord down, and it was indeed there!"

"Is there anything like that dead fat pig, a little bit of tatters is still hiding in this kind of hellish place?"

Cao Yu was very puzzled, what the hell, it was the first time he had seen a little martial art hidden so deeply.

"This old slave doesn't know anything, hehe!"

Steward Yun smiled awkwardly.

"That's it, since they're all here, let's go and have a look!"

He really doesn't have much interest in those so-called martial arts, and what he is really interested in is the reason for the ice and snow here.

Don't look at this space, it doesn't seem to be much, but if you really calculate it, it is half the size of Cao Yu's origin space, which can keep such a large space in an extremely cold climate all year round.

There must be some great treasure that sustains it.

Now there is a Martial Emperor-level thug by his side, how can he look at the baby in front of him and not make a move!

This does not conform to his rogue logic.

It's just that Steward Yun didn't move in place for a long time, and an embarrassed smile appeared on his face.

"What's wrong with you!"

Cao Yu frowned, just now he also relied on his own will to resist these cold airs, in his opinion, this old thing is stronger than him, and he should be able to withstand it.

"My lord, the old slave's strength is shallow, I'm afraid. ”

The meaning of this is obvious, it's not that he doesn't want to bring it, but he really doesn't have enough ability.

Despite the displeasure on his face, there is a sinister feeling when he looks at the details of this old thing.

But now Cao Yu is an arrow on the string, and he has to send it, so he won't kill Steward Yun until he gets the source of the cold here and those martial arts techniques.

It is estimated that the cloud steward also asserts this, so he seems to be a little fearless.

"Blue slave, work hard!"

Cao Yu gave an order and walked forward, and Lan Qiji did as he was told.

As soon as the palms of the two hands were spread, two blue True Yuan shields appeared, enveloping Cao Yu and Steward Yun respectively.

After being covered like this, Steward Yun's face finally softened a little.

Walk forward.

Cao Yu and Lan Qiji followed behind, and soon arrived at a snow field that seemed completely indistinguishable.

Steward Yun stopped, turned his head to Cao Yu and said, "My lord, this is it!"

"What the hell are you talking about! It's empty, where did the lake come from!"

Cao Yu said coldly.

was said by Cao Yu, Steward Yun was not angry, and made a slightly calmer gesture on his hand.

Put an index finger into his mouth and bite it hard, and immediately blood gushed out, or under the urging of Zhenyuan, the blood was not condensed because of the cold.

The drop of blood wrapped in the True Yuan dripped into the snowflakes all over the ground, and the drop of essence blood seemed to have a magical effect, and after touching the snowflakes, it melted the snowflakes on the ground at an extremely fast speed.

In less than five breaths, a lake with a radius of nearly 100 square meters came into view.

Lan Qiji and Cao Yu stood in place, a little confused.

And this kind of operation, it seems that there is something in the snowflakes here!

The lake is round, the water is very clear in color, and there is a mist that I don't know whether it is cold or hot.

This is only the case in the area of the lake, where the rest of the place is covered with snowflakes.

"Isn't this a lake?

A smile appeared on Steward Yun's old face, and he turned his head to Cao Yu and said.

When he spoke, there was a proud look inside, as if the things here were his masterpieces.

Looking at this strange lake, Cao Yu was also a little uncertain, and turned his head to look at Lan Qiji.

After all, he is the most experienced and strongest, and his words are more credible.

"Cao Shao! The water in this lake, if I guess correctly, it is estimated that it is a cold night for 10,000 years, and ordinary people will turn into ice sculptures in an instant, and they will also die instantly!"

Lan Qiji also has a saying, and there is no hidden thing.

Hearing this, Steward Yun's face immediately turned pale.

Didn't these words push him into the abyss of hell! He recommended coming here, it was obvious that he wanted the lives of Cao Yu and Lan Qiji!

In his opinion, the two of them definitely didn't know this thing, but they didn't expect Lan Qiji to have such knowledge.

"Old thing, it seems that you really don't have a good heart!"

When Cao Yu heard Lan Qiji's words, he looked at Steward Yun coldly, from the very beginning, this old thing wanted to use the things in it to kill them.

If no one understands them, and they are fooled, then there is a real possibility that they will be killed.

After all, whoever has a Martial Emperor-level powerhouse in his hands will also be arrogant to the sky!

"My lord, listen to my explanation, if Lord Lan didn't say this just now, I would have said it, as for the solution, it may only be found in the city lord's storage ring."

Seeing the clues, Steward Yun immediately stood up and explained, in this case, if he can't give a good explanation, then it is estimated that he will receive a boxed lunch!

But Cao Yu didn't appreciate it, and threw his backhand over, which immediately made Steward Yun dizzy.

"Is it in here?"

After the fight, Cao Yu continued to speak, and at the same time took out a storage ring, which was the storage ring that Lan Qiji took from Ju Hongkuo's hand.

"What can dodge that cold liquid?"

Looking at Steward Yun with the eyes of a dead man, Cao Yu was also a little unhappy to be honest.

But in order to get the treasure, he still chose to endure it, after all, relying on his own means, he might really have to return home.

"There's a cold bead in there!"

The cloud butler who covered his face immediately replied.

For fear that he would slap him again if he was slow, his face still felt hot in this cold space at the moment, and Cao Yu's slap was really not light.
