Sou!

Tang Chen's speed was very fast, and while expanding his spiritual sense, he found a lot of treasures.

In this regard, Tang Chen was naturally not polite, and all of his brains were included in the Qiankun Ring.

However, due to the limited storage capacity of the Qiankun Ring, Tang Chen was also a little helpless, so he had to give up some treasures, such as some lower-level martial arts and larger treasures.

Of course, these are just some things that are not eye-catching, Tang Chen, who entered the valley in advance, what he wants most is undoubtedly the legendary treasure, Lei Yuan!

The so-called thunder source is a special form of spirit crystal, as we all know, spirit crystal is the crystallization of spiritual energy, and the thunder source is even more terrifying, it is the crystallization of thunder and lightning energy.

According to records, the more dense the thunder and lightning, the more likely it is that the thunder source will be born, so now, the place where Tang Chen is going to be is the deepest part of the valley.

In the deepest part of the valley, thunder and lightning are the most dense, and if the source of thunder has not been found there, then it is even less likely that a source of thunder will be born elsewhere.

Nearly three hours later, Tang Chen came to the deepest part of the valley.

Here, within a radius of a few miles, there was almost no spiritual energy, and there was only the irritable thunder and lightning aura.

"Hmm, the thunder and lightning breath there is the most violent, there should be a thunder source, go take a look!"

Scanning around, Tang Chen suddenly found a cave, did not hesitate, and then stepped on it, and swept towards the cave.

Crackle crackle!

As soon as he stepped into the cave, a thunderbolt as thick as a bucket instantly slashed and smashed into Tang Chen's body impartially.

Hiss~

The next moment, Rao couldn't help but tremble with Tang Chen's body, and then gasped.

Crackle crackle!

At this time, several thunderbolts smashed, looking at the thunder that struck in an instant, Tang Chen didn't dare to hold it up, and immediately sacrificed the thunder and lightning martial spirit.

After sacrificing the thunder and lightning martial spirit, these thunderbolts smashed on Tang Chen's body, as if they were splitting into the air, without a trace of ripples, not only that, but also enhanced a lot of Tang Chen's aura.

It didn't take long for the thunderbolts in the cave to become less and less, and these thunderbolts were all absorbed by Tang Chen.

Then, Tang Chen slowly degenerated, his bones became harder, and the number of purple thunder patterns also increased by three.

At this time, inside the cave, Tang Chen found a pile of purple stones, exuding a violent aura all over his body.

"Could it be that this is the legendary thunder source?"

Walking towards the pile of purple stones, Tang Chen looked puzzled.

Squatting down, Tang Chen grabbed a stone at random, and he clearly felt a stream of thunder and lightning energy gushing out of the stone.

"Hahaha, it's really Lei Yuan, there should be more than thirty pieces in this pile!"

Putting all this pile of thunder sources into the Qiankun Ring, Tang Chen smiled with satisfaction.

"Oh, yes!"

Suddenly, Tang Chen thought of something, and then his face was happy.

"The material used in the Spirit Gathering Array is spirit crystal, and if the thunder source is used as the material, what will happen?"

Thinking of this, Tang Chen immediately became excited, and with the spirit gathering array arranged by the low-grade spirit crystal, he could gather ten times the concentration of spiritual energy.

And how terrifying the Spirit Gathering Array arranged with Lei Yuan can be, this can be imagined, you must know that Lei Yuan is a more precious existence than the best spirit crystal.

Then Tang Chen didn't hesitate, and slapped all the thunder sources into the ground, forming a strange and strange shape.

After doing all this, Tang Chen stood in the middle of the Spirit Gathering Array, and then pressed his right hand on the ground, and the true qi entered the ground.

The next moment, with Tang Chen as the center, the surroundings were filled with a violent aura of thunder and lightning.

Feeling the violent aura around him, Tang Chen hurriedly sat down cross-legged and tried his best to refine these aura.

Huhuhu~

"That's right, the Spirit Gathering Array arranged with Lei Yuan is really extraordinary, and it is more than a hundred times stronger than the Spirit Gathering Array arranged with low-grade spirit crystals!"

Feeling the continuous improvement of his cultivation, Tang Chen was overjoyed in his heart, and couldn't help but be hooked.

Buzz!

The vast furious aura seemed to be desperate, and it frantically poured into Tang Chen's body, making his sea of qi bulge for a while.

Immediately, Tang Chen closed his eyes and held his breath, desperately compressing the true qi in the sea of qi, and with the compression of the true qi, Tang Chen's cultivation was also increasing.

Three hours later, due to the depletion of the thunder source, the Spirit Gathering Array also failed.

At this time, the true qi in Tang Chen's sea of qi seemed to be boiling, and he kept making an explosive sound.

Then, Tang Chen's realm bottleneck, under the impact of the violent true qi, showed signs of loosening.

Rumble!

After a few breaths, the sea of qi in Tang Chen's body continued to grow, and it expanded more than twice!

The Spirit Gathering Array arranged with Lei Yuan was really enough to defy the sky, and it actually allowed Tang Chen to break through two orders in a row, making him reach the eighth level of the Qi Sea Realm!

After cultivating to break through to the eightfold qi sea, in Tang Chen's body, there were still a lot of violent thunder and lightning energy that had not been refined, and it did not stop, Tang Chen continued to refine.

After a while, Tang Chen's cultivation approached the middle stage of the Qi Sea Eightfold, and the thunder and lightning energy in his body was completely refined!

After a while, Tang Chen stood up, and a powerful aura emerged.

"Hahaha, Lei Yuan is really enough to defy the sky!"

After tasting the sweetness of the thunder source, Tang Chen decided to thoroughly search all the places in the depths of the valley and never miss a single thunder source!

Just do what he said, the next moment Tang Chen immediately set off, quickly rushed out of the cave, and then unfolded his spiritual sense, looking for it within a radius of a few miles.

Time passed quickly, in two days, Tang Chen searched almost all the miles around, and of course, the result did not disappoint Tang Chen.

In nearly two days, Tang Chen found a total of more than two hundred thunder sources!

"Calculate the time, now those martial cultivators outside the valley should also come in, it seems that it's time to go out!"

Smiling with satisfaction, Tang Chen turned around and strode in the direction of the outside of the valley.

Outside the valley.

At this time, it was already the third day, and just as Tang Chen thought, most of the martial cultivators had already entered the valley because they couldn't hold back the greed in their hearts.

Of course, there were still a small number of martial cultivators who did not enter the valley, and there were probably a few hundred people.

In fact, it's not that these people don't want to enter the valley, but they all know very well that entering the valley with their strength, let alone competing for benefits, even has problems with self-preservation, so they stay.

They didn't want to enter the valley, but they didn't leave, because in addition to them, there were two other people in the field who didn't enter the valley like them.

One is Yin Yangyan, and the other is Shi Lezhi, everyone knows very well in their hearts that the reason why these two people did not enter the valley was because they wanted to block the valley and take away the treasure from Tang Chen.

This is also the reason why everyone did not leave, because they wanted to see how Tang Chen would face Yin Yangyan and Shi Lezhi after he came out.

"Why hasn't that kid come out yet?"

"Did the man fall in the valley?"

"That's right, there are many dangers in the valley, with that person's cultivation, I can't imagine that he has really fallen!"

"I don't think so, that person is very weird, his strength must be good, and he must have obtained a lot of treasures in the valley!"

There was a commotion around, and many people were impatient, wanting to see how Tang Chen would meet the anger of Yin Yangyan and Shi Lezhi after he came out.
