Sun Chen and the others carefully controlled the magic weapon, and slowly flew towards the dark abyss, the wide crack like a hideous mouth devouring the two.

The two of them went all the way down, and in this abyss, the light was very faint, but Sun Chen found that there were some dots of light on these stone walls and ores, which was a little strange.

Chen Xiyue seemed to see Sun Chen's confusion, and opened her mouth to explain, "Those starlights are emitted by some ores, they are a kind of energy crystals, which are very useful for the cultivation of the Heavenly Cultivation Realm, because you know that once you step into the Heavenly Cultivation Realm, what you practice is no longer spiritual power, but mana, these ores contain rich mana, which can help us cultivate, this kind of ore is called Law Crystal!"

Sun Chen nodded and motioned for her to continue.

"There are abundant magic crystal ores in this underground, and even ore veins, we can even find a way to get a mineral vein, you must know that these ores are extremely pure, a magic crystal is equivalent to an elixir composed of mana, if you get it, you can quickly break through, but usually these ore veins are in the hands of the demon clan, and they are heavily guarded!" Chen Xiyue's eyes revealed a trace of heat, obviously she also had thoughts about this kind of magic crystal vein.

"It's okay, then we can sneak into a vein, I have a ring here, the space inside is almost infinite, we can sweep it away, but only if we can find a vein!" Sun Chen's eyes revealed a fiery fire, he was about to break through to the Heavenly Cultivation Realm, and he would also use the magic crystal at that time, so it was better to take this opportunity to sweep it.

"Well, we found a small vein last time, but we didn't dare to do it, there are people from the demon clan guarding it, and it's hard to sneak in!"

"Okay, this time we'll go and sweep it away, and then we'll be half of us!" Sun Chen opened his mouth, he was excited, he didn't expect Chenxi Yue to know a place, he secretly transmitted a voice to Li, "Senior Li, do you have any tattoo techniques that can cover up your own breath or change your breath?"

"Hmm, you have found a vein?" Li suddenly became interested, and laughed, "Haha, Sun Chen, where is this vein, we must get it, with these magic crystals, I will be able to recover some strength, I will be able to wipe out the consciousness of this Yuan Furnace and refine it into an unconscious spirit, then you will be able to easily control this furnace, and then you will even be able to discover a secret of this Dan Furnace, it was because of the secret of this Dan Furnace that we made a move on this Alchemy Demon Venerable!"

"Oh, this Dan furnace still has a secret? Then you wear out its consciousness, why don't you explore this secret yourself? and let it be given to me?" Sun Chen showed a hint of disdain.

"Hehe, if it were possible, I wouldn't let it go to you, I don't have a body now, if I refine this consciousness, I will become the spirit of this Dan furnace, I won't be so stupid, although the secret is good, but I don't want to live a cage-like life!" Li hurriedly said, of course he also has his own selfishness, at the moment when Sun Chen refined the consciousness of the Yuan Furnace, he had a slight chance to break through the seal.

"Okay, I'll get my hands on this vein when I get my hands on it, but the question now is if you have the aura alteration technique?"

"Of course there is, I gathered a lot of secret techniques of the pattern technique back then, and used it to study, just to break through that one, but unfortunately it was useless, so I hit the idea on the body of this Yuan Furnace, but I didn't expect to end up like this!" Li said slowly, as if he was in deep thought, and then he transmitted a divine thought into Sun Chen's sea of knowledge.

"Concealing the heavens, one mimicry, two mimics, three mimics, four replications, five concealing the heavens and the sea, heaven and earth are difficult to distinguish, and there is the ability to conceal the sky!" Suddenly, a line of golden handwriting appeared in his sea of knowledge, Sun Chen glanced lightly, and slowly exhaled, "This pattern technique is too against the sky, it's terrifying!"

"Horror fart, this tattoo technique is almost a waste, no one has ever been able to cultivate more than three, at most it can only be cultivated into two, this kind of tattoo is a bloodline tattoo technique, only a special bloodline can be cast, this is what I snatched from a star clan powerhouse back then!" Li said lightly, although his mouth revealed disdain, but obviously he had suffered from this technique.

"Star Clan?"

"That's one of the major races in ancient times, their clan practiced star patterns, played Zhou Tianshen, claimed to have done everything, captured the mystery of heaven and earth, and changed Xuanhuang, the little girl next to you is a member of the Xingchen clan, and the bloodline is not low, she may still be a member of the royal family!" Li Yu was not shocked, Sun Chen was also shocked, he didn't expect Chenxiyue to be a star clan, no wonder he always felt that she was very mysterious, and he even had a feeling of being seen through when they met for the first time.

Sun Chen secretly comprehended the Heavenly Concealment Technique and wanted to cultivate, but he always felt that there was an obstacle in his body that could not allow him to cultivate, he secretly sighed, it seemed that he could only let Chenxiyue practice.

No, I can cultivate, I have the bloodline transformation of the blood killing god king, as long as the bloodline in the world is bloodline, it should be controlled by him, thinking of this, Sun Chen said to Chenxiyue, "Can you give me a drop of your essence blood?"

"Why do you want my essence blood?" Dawn Moon looked vigilant, did he want to deal with me?

"Don't worry, I won't let you suffer!" said that, Sun Chen passed on the Heaven-Concealing Technique to her.

"It's actually a trick to hide the sky, how can you have this technique?" Chen Xiyue looked excited and surprised.

"Haha, I didn't know about this technique, and I also knew that you were from the Xingchen Clan, but it doesn't matter which clan you are, now you can see my sincerity!" Sun Chen smiled, he knew that Chenxi Yue would have this expression.

There is only one copy of this Heavenly Concealment Technique, which was robbed by Li back then, and the Star Clan only has its remnants!

"Sun Chen, I'm getting more and more unable to see through you now, I even have the Concealment Technique, I don't ask where you got it from, this is my essence blood!" The significance of this Concealment Technique to the Xingchen Clan is too great, and she can't refuse at all.

A drop of blood that seemed to be shining with starlight suddenly appeared from the tip of Chenxiyue's jade finger, her face turned slightly pale, and then the drop of blood floated towards Sun Chen, her eyes were puzzled, she wanted to know what Sun Chen wanted to do.

I saw Sun Chen take a big breath, and the drop of blood shining with the brilliance of the stars was suddenly sucked into his abdomen.

"What?" Chen Xiyue was even more confused, Sun Chen actually swallowed her drop of essence blood directly.

Next, I saw a blood light suddenly rise from Sun Chen's body, and then a symbol appeared from the blood light, which was the formation pattern, that is, the Great Dao password, they were constantly combined, connected, and flickered with each other, and finally, the blood light flashed, and a star-colored light suddenly appeared on Sun Chen's body.

"What? how is it possible?" Chen Xiyue's eyes widened suddenly, Sun Chen actually analyzed her bloodline, and what surprised her even more was that at this time, Sun Chen's bloodline actually became the bloodline of the Xingchen Clan, and there was actually a connection with her bloodline, a feeling of flesh and blood, which immediately made her blush.

Because Sun Chen formed the bloodline of the Star Clan through her essence blood, it was natural that Sun Chen had a wonderful induction between her.

Obviously, Sun Chen also felt this, he smiled slightly, but there was a meaning in his smile that only Chen Xiyue could understand, which made her a little annoyed and angry, and snorted coldly.

"Haha, what a wonderful feeling!" Sun Chen closed his eyes slightly, Chen Xiyue's psychological activities were faintly captured by him, she was scolding Sun Chen in her heart for being shameless and obscene, Sun Chen was suddenly helpless, in addition, he could also feel the power of the stars in the space.

He secretly practiced according to the Heaven Concealment Technique, and actually cultivated the first layer directly, without any obstacles.

Sun Chen did not continue, but hid the bloodline of the Xingchen clan and did not urge it again.

Feeling that the feeling of peeping disappeared, Chenxi Yue secretly breathed a sigh of relief and glared at Sun Chen fiercely.

Sun Chen was a little weak-hearted, and said with a smile, "You hurry up and practice the first layer of that Heaven Concealment Technique, and then we will use this Heaven Concealment Technique to disguise ourselves as demons and secretly enter that mineral vein to steal the magic crystal!"

Seeing that Chenxi Yue was really attracted by the Heavenly Concealment Technique, Sun Chen suddenly exhaled a long breath, fortunately diverting her attention away.

After a while, a star-like brilliance flashed in Chenxiyue's eyes, and the first layer was directly refined by her.

"Okay, now that you and I have both cultivated the Heaven Wandering Technique, we can do that thing of stealing the sky, the two of us can pretend to be demons, not only in this underground world, which is extremely safe, but also the demons in this underground world will not be defensive against us at all, we can hunt the demons in large quantities in exchange for merit!" Sun Chen immediately suggested, this kind of opportunity is rare.

"Well, it's really good, but I have one condition, that is, you are not allowed to pretend to be a demon, you are my servant!" Chen Xiyue said with a sly face, and Sun Chen looked like he would fight with him if he didn't agree.

Sun Chen was like a docile little sheep under the authority of Dawn Moon, and it was difficult to resist at all, he knew that she was afraid that Sun Chen would spy on her.

Okay, just obey it, Sun Chen doesn't care about it, as long as he can get benefits.

"Bang!"

After a few hours, Sun Chen and the others finally fell to the ground, and before they could stand firmly, they suddenly felt a gust of fishy wind blowing in their faces.

Sun Chen and the others retreated suddenly, only to see dozens of blood-colored demon wolves appear in front of them, this kind of demon wolves do not have much wisdom, they have a body of brute strength, most of their consciousness is corroded by the demonic qi underground, and they only have the instinct to attack.

"It's actually an abyss demon wolf, but this kind of demon is still relatively easy to deal with!" said Dawn Yue.

Sun Chen had the heart to test the water, and directly emitted golden sword qi from his fingertips.

"Boom!"

Suddenly, dozens of golden sword qi were horizontal, and dozens of abyss demon wolves were slaughtered in an instant.

Without wasting their efforts, dozens of abyss demon wolves suddenly turned into corpses.

"The essence of these demon wolves is gathered on the blood-colored spar on the top of its head, these are the essences of the abyss demon wolf, which can enhance the strength of the physical body, and it is not too useful, but it can also be exchanged for some merit points!" Chen Xiyue explained.

Sun Chen sent out one sword qi after another, and put away the spar on the head of the abyss demon wolf, "Let's continue to move forward, kill all the way, and wait until we get out, and I will give you these things!"

"Okay!"

In this way, Sun Chen and the others almost crushed all the way, killing all kinds of demons, as for Li using his divine thoughts to strafe the surroundings, they also found some elixirs, and they killed the demons all the way to collect elixirs, but it was extremely comfortable.

After about half a day, Sun Chen and the others were a little tired mentally. He was about to sit down and rest, when suddenly, a silver sword qi rushed into the sky, cutting through the space like a bolt of lightning.

"Hmm, this sword qi is horizontal, presumably someone is fighting with the demon again, this sword qi is silver, like a starlight, with the breath of my Xingchen clan, is it a person from the Xingchen Sect?"

Chenxi Yue let out an exclamation, and she knew that the strength of this sect should not be underestimated.

"Xingchen Sect, let's go, let's go over and take a look, and we have the Heaven Concealment Technique, there won't be any danger!" Sun Chen took the lead and swept in the direction of the silver sword qi
