The two of them dived all the way down, a full stick of incense or so, and finally touched the bottom, looked around, only in a marginal area, saw a few bubbles bubbling up, and did not find a vortex all the way, and felt a little comforted.

"There!"

Cao Yu pointed in that direction and swam over first.

In the past, Cao Yu saw that there were still small golden threads on the ground at the bottom of the lake, and at a glance, he knew that it was used to burn the formation!

When they arrived at the spring, Cao Yu and Lan Qiji were a little dumbfounded.

Under the bottom of this lake, there is even a formation!

"Made, what the hell is this goddamn city lord hiding, there are so many doorways!"

Cao Yu couldn't help but curse secretly.

Now what he is most curious about is how the city lord who was killed by Lan Qiji before, Ju Hongkuo, got in and out of here safely.

It's really incomprehensible!

However, the people who know now may have almost died, and the so-called cloud butler doesn't seem to have come down many times and was killed unconsciously.

"Cao Shao, this is a formation, what should I do?"

Although Lan Qiji's strength reached the early stage of Emperor Wu, he basically didn't know anything about the formations, especially cultivators like killers, they wouldn't spend time studying these obscure and very trivial things at all.

The general formation is to be in a specific environment in order to get the best effect.

They generally choose the best environment for themselves to shoot, and naturally they will not look for any formations or places that are easily exposed.

"Don't worry!"

Cao Yu waved his hand, for him, a saint-level array mage, although he had only absorbed the inheritance and had not practiced cracking and arranging many formations, Tian Xuanzi's terrifying experience had already made him a grandmaster-level existence.

Now, when he sees the formation in front of him, he naturally won't be clueless.

However, there are thousands of formations in the world, and there are many changes, what he needs to do is to grasp the principle of inseparability, find the key point of the formation cracking, and naturally easily solve the impasse in front of him.

I saw that Cao Yu looked like a knowledgeable person, look here, touch there, although it is under the ice lake of ten thousand years of cold liquid, it will not have much impact on him.

"Since this formation can last for so long in the bottom of the lake of the 10,000-year cold liquid without losing the power of the formation, it is naturally related to the 10,000-year cold liquid, and observing the surroundings, there is no trace of the spirit stone wherever the formation etching line reaches, and it is this 10,000-year cold liquid that maintains the formation!"

After Cao Yu observed, he said to himself.

"Cao Shao, do you still know the formation?"

Lan Qiji looked at Cao Yu with a surprised expression.

After all, judging from Cao Yu's words just now, if you don't have a few decades of Taoism, otherwise you can just look at it casually, and you can see the ins and outs of the formation clearly, not to mention the way to crack it.

"A little bit of understanding, a little bit of understanding!"

Cao Yu waved his hand, looking like a humble gentleman.

Hearing this, Lan Qiji admired it even more, and the originally dull look in his eyes actually changed a little.

At this time, Cao Yu's mind sounded the unique mechanical prompt sound of the Holy Hell System.

"Congratulations to the host! Increase the trust of the sin slave, reward the host for cultivating to break through a small realm, and the sin slave to upgrade to a C-grade high-grade sin slave, and break through a small realm in strength!"

"Wow rub! Cool!"

Cao Yu almost laughed, now I feel that he is really cool to pretend!

It seems that his unintentional behavior just now directly improved Lan Qiji's trust and worship of him, and then, after the system recognized it, it directly gave a big benefit!

Strength breaks through a small realm!

In other words, his strength has reached the Martial Emperor Eightfold!

You know, he only broke through the Martial Emperor Seventh Layer yesterday, and if others knew about his rocket-like ascension speed, it is estimated that his jaw would fall.

What surprised him even more was that Lan Qiji's strength had directly broken through a small realm!

This holy prison system is too Nima against the sky!

It seems that in the future, he must pretend to be forced in front of Lan Qiji to enhance his admiration and trust in himself, so that his strength will be improved rapidly.

After the mechanical prompt sounded in Cao Yu's mind, there was an invisible rule force operating beside Cao Yu, and soon, Cao Yu's strength was forcefully raised.

After feeling the situation in his body, originally in Cao Yu's opinion, this kind of seedling pulling to promote general improvement will definitely lead to unstable foundation.

But after seeing the True Yuan and Dantian in his body, he was completely relieved.

I didn't feel the feeling of emptiness just breaking through, but I was full of strength, and all aspects of my body had undergone some changes, which was the benefit of a breakthrough in strength, and normal conditions would bring all-round improvement to my body.

Cao Yu had just finished his ascension here, and Lan Qiji also felt an invisible force acting on him.

"Ahh

For the strong, they are extremely sensitive to their bodies, and they will react at the slightest hint of wind and grass, but the terrifying rule power of the Holy Prison System is a tough promotion, and Lan Qiji can only stand in place with fear on his face.

But the next moment, he was ecstatic!

"I... I.. I break through ... Breakthrough ... ”

When he said this, Lan Qiji's whole body trembled, his eyes widened, and he looked at his body incredulously.

"Cao Shao! I broke through! Hahaha! It's been a hundred years, and I've finally broken through!"

Lan Qiji was too excited, kneeling directly under the ice lake, tears couldn't stop flowing out, but because the bottom of the lake was too cold, there were cold beads in his body to keep, and those tears that flowed out directly formed into tiny tears ice crystals.

At this time, Lan Qiji didn't know what was going on, and looked at Cao Yu a little blankly.

He just felt that he saw that Cao Yu had also dabbled in the formation, and there was a spontaneous admiration in his heart, after all, with his experience, it was rare to see someone who could be strong in all aspects.

And what Cao Yu showed just now is not the kind of three-legged cat's kung fu, there is still a certain level.

Therefore, he sincerely admires Cao Yu!

"Don't be surprised!

Cao Yu didn't say anything about the Holy Prison System, although Lan Qiji was his slave, he didn't know about the existence of the Holy Prison System, he was just a slave in his soul and was very loyal to Cao Yu.

"It's you, Cao Shao!"

Although he didn't believe it in his heart, only Cao Yu and him were present now, but what made him strange was that Cao Yu's strength had also improved by a small realm!

In his soul subconscious, he absolutely trusted Cao Yu, because he had no doubts about what Cao Yu said.

Sin Slave Blue Qiji, thank you master!

There was not too much nonsense, but Lan Qiji still knelt down and kowtowed to Cao Yu three times.

This is the heartfelt gratitude of his soul, and it is not because the Holy Prison system enslaves his soul that he did it!

"Don't worry, follow me, your benefits are indispensable, and your strength will also improve rapidly!"

Cao Yu was naturally very happy to see the strength of his slaves improved, for him, as long as Lan Qiji improved, then his safety would be more guaranteed, after all, when he went to the Blue Leaf Empire, there must be endless masters, and he had strong thugs in his hands as the backing, and he was more confident.

"Swear to follow Cao Shao!"

Encouraged by Cao Yu, Lan Qiji was even more excited.

At this time, the prompt sound of the Holy Prison System sounded in Cao Yu's mind again.

"Trust level increases, the sin slave is promoted to the second grade lower grade sin slave! 1000 trust points are needed to improve the next stage!"

This time, there are no overwhelming rewards, just an increase in the level of the sin slave.

He still doesn't know what this so-called Class C and Class B sin slave means, and what benefits it has.

Xiao Yuan's bastard asked, but he also looked confused, so he gave up.

Presumably, when it comes to a certain situation, he will naturally know that after a long time, he can figure it out by himself.

"Okay, you can rest for a while, and I will crack this formation!"

Happy to happy, Cao Yu has not forgotten his task, and now there is a time bomb in the origin space, and he must find a way as soon as possible.

After some comparison and testing, this formation was finally determined.

"Ice Array!"

This formation really takes advantage of the natural environment of the 10,000-year-old cold liquid here, and then it can operate endlessly here, and the purpose of this formation is simple, that is, to close.

Naturally, I don't want the treasures or angry treasures below to be discovered.

Knowing the formation, a slight smile appeared on Cao Yu's face.

This formation is very easy to crack, but it is very difficult!

Why!

Because, it takes the power of extremely hot flames to burn the traces of the formation engraved on the surface of the bottom of this lake, so that the formation can be cracked.

The difficulty is that this is the bottom of the lake of the 10,000-year-old cold liquid, and ordinary monks, if they don't have a cold bead, they won't even dare to touch the 10,000-year-old cold liquid, let alone go down to the bottom of the lake to crack the formation.

However, for Cao Yu, a monk who was like an open hanger, it seemed a little too easy.

In his hands, not only does he have one of the thunder fires, but his body can easily release flames after being tempered by the origin of fire, so it is not too easy for Cao Yu to crack this formation.

I saw a trace of flame coming out of Cao Yu's fingertips, this time he didn't choose to use thunder fire, after all, cracking such a formation is not necessary to waste thunder fire, before he got the thunder fire origin fire, he used it once less, it was an excellent weapon for Yin people, and he was naturally reluctant to use it easily.

Soon, Cao Yu burned all the arcs along the formation pattern at the bottom of the lake.

As some of the others were burned out, there was a click, and the place where there was an etching line began to move away automatically.

After the crack was formed, the strange thing was that the 10,000-year-old cold liquid did not pour into the bottom, and it seemed to be unaffected by gravity!

Cao Yu and Lan Qiji stood on the edge, looking at this strange scene, their eyes flickering.

Soon, the full scene was revealed, and a gap resembling a pentagram was at the bottom of the lake.

Cao Yu couldn't grasp this situation, and said to Lan Qiji: "Lan Nu, try if you can go in here"

Through the gap, Cao Yu could see the white expanse, although he couldn't see anything, he felt that there must be something terrible in the decentralization

"Okay, Cao Shao!"

Lan Qiji, now his trust in Cao Yu has increased, although he can't be directly loyal to Cao Yu after the Holy Prison System is lifted, at least his hostility towards Cao Yu has decreased a lot.

However, after Lan Qiji came down here, he saw so many strange things, and he still felt a little empty in his heart.

There was some trembling trembling in his hand stretched down, and when he passed through, nothing happened, but the next moment, Lan Qiji let out a scream!

"Ah!! okay... Good.. It's cold!"

"Damn, what are you calling nonsense, it's not cold down here!"

Cao Yu was also frightened, thinking that there was something terrifying, so he was stunned and retreated dozens of meters!
