Xie Chen and the others kept walking towards the depths of the mine, which was very desolate and uninhabited.

Xie Chen found that the deeper he went, the more precious materials he discovered, and there were several materials that were rare even in the upper plane.

Nebula Stone, Void Stone, and Canglan Stone are all extremely precious refining materials, which are used to refine Shenwu, Space Magic Weapon, and Time Magic Weapon respectively.

If these materials appeared in the upper plane, they would definitely attract the frenzied snatching of the major sects.

The group continued to walk all the way to the depths of the mine, and by this time the sky had already darkened, and the blue sky was gradually covered with a thin black veil.

For Xie Chen and Li Jiayi, there is no difference between dark and daylight.

Xiaohong flew around and had a lot of gains, two eagles, four or five grass snakes, and kept showing Xie Chen his gains.

A few people sat on a big bluestone and ate delicious barbecue, but the fire that Xiaohong spit out was too bursting, and most of the meat was roasted.

Little Douzi said excitedly: "Little Red Bird, you can breathe fire!

Look at Xiaohong and say proudly: "Little trick, after a long time, you will worship me even more, until you can't extricate yourself." ”

Xie Chen and the others were already numb to Xiaohong's shamelessness, and they quickly finished their dinner and walked towards the depths of the mine again, as if there was no end.

They had gone a short distance and noticed a small lake ahead.

At this time, it was already past 8 o'clock in the evening, and there were no lights around.

But the lake was bright.

Xie Chen felt that this lake must be unusual, and his divine sense quickly enveloped the lake.

Through the clear lake water, Xie Chen's divine sense kept approaching the light source, but he couldn't sense the existence of the light source.

Xie Chen couldn't figure it out, so he planned to go down to the lake to find out in person.

So he said: "Jiayi, Xiaodouzi, you wait here for a while, I'll go down to the lake to have a look, and I'll come up soon." ”

"Then be careful, this lake is so strange!"

Li Jiayi advised.

"Well, don't worry. ”

After Xie Chen finished speaking, he jumped directly into the lake.

The moment he jumped into the lake, he felt that the water was very warm, as if there was infinite energy in it.

He kept swimming towards the center of the lake, and the feeling grew stronger.

Using his divine sense, he still couldn't find any results, so he kept diving, preparing to go to the bottom of the lake to find out.

Xie Chen quickly dived to the bottom of the lake in the center of the lake, and he felt that his divine sense could not penetrate the bottom of the lake.

It's as if it's cut off by some kind of barrier.

And the barrier is neither a formation nor a man-made one.

Just when he was at a loss, he suddenly felt that the Heavenly Fire Crimson Thunder Flame in the Burning Heaven Ding had obvious agitation.

It stands to reason that if the heavenly fire does not produce a fire spirit, it is not conscious, what is the situation?

He simply released the Crimson Thunder Flame from the Burning Sky Ding.

At the moment when it was released, the surrounding lake automatically dispersed, forming an isolated space.

At this moment, the bottom of the isolated space slowly melted, revealing a black, egg-sized, translucent crystal ball.

At this time, Crimson Lei Yan suddenly burrowed into the crystal ball.

Xie Chen reached out to take the crystal ball, but he couldn't hold it.

He didn't believe in evil, and he tried his best to get it, but he still didn't move.

"What the hell is this? I can't even hold it so small. ”

He changed his way and used the Burning Heaven Ding to suck it again, but it was still as steady as Mount Tai, not moving a bit.

He really hadn't encountered such a heavy thing, and there must be space inside it, otherwise how could Crimson Lei Yan get in.

Crimson Lei Yan actually came to consciousness when he met him, and the heavenly fire was born of heaven and earth, and the source of heaven and earth was ......

Thinking of this, Xie Chen suddenly remembered the jade slip of the Guiguzi predecessor that he had seen in the secret realm before.

The strongest of the Three Realms mentioned in it competed for the source of chaos, causing it to shatter and split into eight parts, and its whereabouts are unknown.

Can't even deduce the Great Deduction Technique, could this be one of the fragments of the Chaos Realm Source?

Xie Chen was frightened by his bold guess, he wouldn't be so lucky!

Although it is only one of the eight fragments, it is not to be underestimated.

But even the Chaos Realm Source Fragment can't be taken away!

Even the ancient artifact Burning Heaven Ding can't be sucked in, and the feeling of discovering the treasure and not taking it away is conceivable.

Xie Chen thought that he had collected the Burning Heaven Ding before, and it was by relying on a drop of essence blood that he could control.

So he cut his finger and forced out a drop of essence blood.

The moment the blood was dropped into the crystal ball, I saw that the essence blood actually melted into it, but the crystal ball disappeared.

He sensed it carefully, and there was nothing unusual at the bottom of the lake, but at this time, there was a very comfortable feeling coming from Zhihai.

He looked through his soul and saw that the black crystal ball had actually entered his sea of consciousness.

And it can feel the crimson thunder flame in it through the crystal ball.

He felt that the crimson thunder flame was slowly developing spirituality in it.

Xie Chen wanted to know more about the crystal ball, and as soon as he had the idea of going in to take a look, he found that his divine soul had really come to the inside of the crystal ball.

I saw that it was a space of its own, almost a few hundred meters in circumference.

The outside felt like it was sealed, and you couldn't see what was going on inside.

After reluctantly investigating, he felt that Zhihai was tumbling, and he had a splitting headache, so he simply stopped probing.

He's going to study it again when he's going to have some time.

Xie Chen quickly surfaced with great excitement.

At this time, he found that the lake was already dim, presumably because he had taken away the Chaos Realm Source Fragments!

He quickly swam back to the shore, and Li Jiayi and Xiaodouzi hurriedly walked over.

"Why have you been around for so long, and we just noticed that the lake had dimmed, and you floated up in a few moments, what happened?"

Li Jiayi asked anxiously.

"Don't worry, it's okay, I got a strange crystal ball from the bottom of the lake.

It's not clear what it does, but I thought the crystal ball was taken away by me, so the lake no longer glows!"

"Okay, you're fine, so let's continue to investigate?"

"No, I found that there were no mines on the other side of the lake, and there should be no more of what we needed. ”

After Xie Chen finished speaking, he looked at Xiaodouzi and said, "There is no one here, it is relatively quiet, and it is very suitable to open up the meridians here."

You take off your shirt and open up the meridians for the teacher so that you can cultivate. ”

Xiaodouzi listened to Xie Chen's words, was excited, and quickly took off his shirt.

Xie Chen asked him to sit cross-legged on the ground again, without distractions.

Seeing that Xiaodouzi had been done as required, he quickly released his aura and pointed at his second vein.

It's easier to open up the meridians when you get to the foundation building realm.

He quickly guided the aura to the dantian to form a whirlpool, and he could see that the center of the whirlpool gradually turned purple, and a purple immortal seed slowly formed.
