With a tacit understanding, the two of them moved a little faster, and after about fifteen minutes, Zhan Chen saw a huge hole appear in front of him.

Sori pointed to the entrance of the cave and said, "Zhan Chen, that's the cave where I found the Cold True Iron Mine. ”

"Let's do it quickly. Zhan Chen rushed to the entrance with all his might.

Sori followed suit.

As soon as he came to the entrance of the cave, Zhan Chen felt a formidable cold air coming towards him, which made him shiver.

He was very surprised in his heart, with his own cultivation, he was not afraid of the cold in the universe, but the cold here was like a life, drilling straight into his body, so that his powerful body felt cold.

"Zhan Chen, run the exercises quickly to resist the cold, the cold here and the outside world are fundamentally two kinds, which contains a powerful ice law, if you despise it, you will soon become an ice sculpture. Sori reminded him in time.

"It's actually the Law of Ice!" Zhan Chen said in surprise, this was the first time he had seen the power of the Law appear without the cultivator's cast.

"What's so strange about this, you know, it was the Deep Sea Venerable who created this mountain, I told you before, this mountain peak contains the power of the law everywhere, if you have dabbled in the law of ice before, you can use this place to break through. ”

"I see. Zhan Chen immediately began to use his star power to expel the cold qi that pierced into his body.

Fortunately, the ice laws here were not aimed at anyone, so Zhan Chen was able to adapt to it quickly.

The two walked into the cave, and Zhan Chen asked again: "Senior, what kind of cold devouring monsters are, what magical powers do they have, and what are their weaknesses?" ”

Sori shook his head and said, "They look like a bunch of dolls made of hedrons, and they don't have any tricks, but they are better than the rough skin and thick flesh, and there are a lot of them. Hearing is false, seeing is believing, as long as you get to the place, you will understand. ”

Zhan Chen stopped talking and continued to walk forward, it was very strange that he felt that the strong gravity on the mountain before had disappeared, and he already had a trace of realization in his heart, probably what the Deep Sea Venerable had exerted on the outside of the cave was the law of gravity.

But inside the cavern is the law of ice, and the two laws cannot coexist.

That's why he felt the pressure on his shoulders disappear.

At this moment, a faint blue cold light came from the depths of the cave, and the surrounding temperature began to drop further.

Zhan Chen had to speed up the operation of the star power, and also resisted the gradually stronger cold air.

Suddenly, Solri stopped his steps and said to him: "Zhan Chen, I can only send you here, and then you have to rely on yourself to explore forward, you should understand the reason, as long as I take a few more steps forward, the Chill Devouring Demon Monster you face will be equivalent to the level of the six-star stellar realm." As for the appearance of the cold spirit real iron, you should also understand it. ”

Zhan Chen nodded and said, "Senior, don't worry, if it's really as you said, I will definitely be able to get the treasure." ”

He took a deep breath and strode forward.

At the end of the blue light, he was presented with a magnificent scene, which was covered with cold crystals emitting sapphire light, whether it was under his feet, on the stone walls on both sides, or on the ceiling above, full of romantic fairy tale atmosphere.

But Zhan Chen knew the horror of these cold crystals very well in his heart, and with the strength of his flesh, he would touch them without any protection

, will definitely freeze off the arm.

"Wealth and danger, didn't I come all the way here?" Zhan Chen secretly cheered himself up and strode into the area surrounded by cold crystals.

Walking only a hundred meters, he suddenly noticed an anomaly in front of him, several humanoid monsters covered with cold crystals were buried in the cold crystals, if he didn't pay careful attention, it was really possible to ignore them.

"Those are the Chilleaters. Zhan Chen took out the seven-star sword and set it forward step by step.

As he passed the Chilleaters, they burst into flames and struck him.

"One, two, three, four, four at once? Zhan Chen muttered to himself as he swung the seven-star sword in his hand and slashed at those monsters.

"Ding, ding, ding, ding!"

The sword slashed at them and slashed them away, but it didn't seem to do any real damage to them.

As soon as they fell on both sides, they immediately got up from the ground and pounced on Zhan Chen again.

His brow furrowed slightly, it was obvious that it was not enough to defeat these monsters with ordinary attacks, so he incorporated the law of water into his attacks.

"Light Wave Slash!" Zhan Chen shouted, unleashing his strongest attack, and an arc-shaped sword qi spread around him.

Another advantage after comprehending the law of water is that it can transform its attacks into various forms, after all, water has no normality, and it is far from the uniqueness of the law of water.

The four monsters were hit at the same time, their bodies as if frozen in mid-air, and then exploded into ice chips in unison.

Seeing that they were finally defeated, he showed a smile: "Fortunately, they can still be defeated." ”

He subconsciously searched for the crystal nuclei of those monsters, only to find that there was nothing lying on the ground except a pile of ice chips.

"Could it be that these Cold Devouring Monsters are lifeless beings?" Zhan Chen thought in shock.

However, this may explain why they can be strong when they are strong, because only the puppets created by the powerhouses of the Black Hole Realm will be endowed with such abilities.

"I have to hurry up!" Zhan Chen walked back forward.

However, the crisis was not resolved, and he had only taken a few steps when he noticed a dozen or so Chilleaters in front of him, roaring and rushing towards him.

"Light Wave Slash!" Zhan Chen didn't dare to keep it, and once again sent out the strongest blow.

This time, however, he did not destroy all the enemies, only destroying the six who rushed at the front, and the other monsters continued to attack him.

Zhan Chen hurriedly cast footwork and passed through them, but what he saw was an even more desperate scene.

One after another in the passage in front of him, the Chill Devouring Monsters came out of thin air from both sides, blocking in front of him, and there were hundreds of them.

"Damn, is that the premise? Chill Eaters seem to be able to be created endlessly, and my stamina is limited after all. But so what, since the trial is so difficult, it means that the rewards after passing will be richer!"

Instead of smiling at the pressure.

"Let me pass through in one go!" Zhan Chen rushed towards the depths of the cave as fast as he could, swinging the sword in his hand continuously, repelling the enemies who stood in his way one by one.

Since he didn't know how many enemies would be waiting for him in the future, this time he didn't use the light wave to slash, but chose to conserve his strength, but in this way, he also blocked his retreat.

Suddenly, a piece of silver cold true iron appeared on the side of the passage, and Zhan Chen only recognized it slightly, and he was convinced that this was what he wanted.

So he hurriedly stretched out his hand to grab it, but a biting cold air came from the cold iron, and it only froze off a layer of skin on his palm in an instant.

Zhan Chen subconsciously retracted his palm, his brows furrowed slightly, it seemed that it was impossible to get this piece of cold true iron without some effort.

But the enemy wouldn't give him this chance, and in the time he paused for a moment, the Chill Eaters surrounded him on both sides.

"Damn, it's so hard to get this piece of cold spirit true iron, what the hell should I do?"

Although he thought so, Zhan Chen's body made a choice intuitively, that is, to give up the treasure in front of him and continue to rush inside.

Next, Zhan Chen swung his sword like the wind and finally broke through to the end of the passage, only to feel that his eyes suddenly became spacious and came to a huge space.

A strange scene was staged again, and the previously ferocious Chilleater monsters all came to an abrupt end when they pursued Zhan Chen to the entrance of the passage.

They just stayed at the intersection, staring at Zhan Chen, but they didn't dare to take a step forward.

It was as if there was something in the space that was restricting their access.

Seeing that those Chill Devouring Monsters didn't chase after him, Zhan Chen finally breathed a sigh of relief, turned his head and began to observe everything in the space.

This space is not large, surrounded by pure white crystal walls, but a large spirit array is carved on the ground.

Zhan Chen's eyes were naturally focused on this spirit array, but his attainments in the spirit array were not enough, and he didn't understand the true function of this spirit array, so he didn't dare to activate it at will.

So, he summoned Caiyuexin out, and by the way, he used his strength to protect her from the strong cold around her.

"Xin'er, help me study, what is the effect of this spirit array?"

Although Cai Yuexin's cultivation is very limited, and she has only reached the three-star realm so far, she is indeed a genius in the formation.

She carefully studied the formation with her colored pupils for a while before saying, "Zhan Chen, according to my analysis, this is a teleportation spirit array. ”

"Teleportation Spirit Array?" Zhan Chen was slightly stunned.

"But I don't know where this spirit array will be teleported. Cai Yuexin replied honestly.

"Then do I want to enter this spirit array, or not?" Zhan Chen muttered to himself.

"Since it's a trial, it should be a good thing as a reward for passing. Cai Yuexin said subconsciously.

"You're right. Zhan Chen couldn't help but kiss her on the cheek, as if he had figured it out.

Cai Yuexin's face turned red and said, "I'm going back to cultivate, and then I got into the spirit beast ring in one fell swoop." ”

Zhan Chen couldn't help but smile bitterly and shook his head, he began to observe the spirit array in front of him again.

This spirit array contained thirty-six array eyes, so he took out thirty-six low-grade star crystals and tried to fit them into the array eyes one by one.

When he inserted the last star crystal, the spirit array was immediately activated, and before he could come back to his senses, he felt a flower in front of him.

Zhan Chen couldn't help but be frightened, but he quickly calmed down, because he didn't feel the danger just now.

When he looked around closely, he found that his surroundings had changed, and he seemed to have come to the bottom of a sea.
