Chapter 915

These spirit crystals, formed after thousands of years, are naturally thunder crystals.

A thunder crystal is worth hundreds of times more than an ordinary spirit crystal.

Moreover, in the thunder crystal, not only is the spiritual power rich, but most importantly, after mixing with the power of the Heavenly Thunder Calamity, the spiritual energy has also mutated and become a completely different power. The benefits are endless.

Therefore, thousands of years ago, thunder crystals were gradually discovered by humans, and then monks from the thirty-six continents frantically flocked to the primitive continents to search for thunder crystals.

Until now, on the vast primitive continent, the places that monks can touch are still only a small part.

For any monk, after reaching the Mahayana realm, the speed of cultivation will become slower and slower, or even stagnate. Even the most powerful Lingfu cannot break this shackle.

And only Lei Jing can get rid of this bondage and quickly improve the cultivation base of Mahayana monks.

Lin Yi and Hongyan finally rushed into the robbery pit, above which were surrounded by dozens of guards.

These guards, of course, came to guard the entire robbery pit, and also to collect taxes for Liugong.

The robbery pit is huge, and there are a lot of cracks and caves in the pit from top to bottom, so the scope of searching is even wider.

Hundreds of monks rushed into the robbery pit, and in a blink of an eye, not a single figure was seen, and all of them got into those cracks and caves.

"Lin Yi, remember that the thunder crystal is very different from the ordinary spirit crystal. It is bigger, and you can see the obvious lightning in the crystal!" Hong Yan said carefully, "Besides, the thunder crystal is very fragile, so I found it. Be sure to squeeze it carefully, otherwise it will explode!"

Lin Yi nodded, "Got it!"

"Let's go, let's search separately!" As he said, the red smoke rushed into a bottomless stone cave.

Lin Yi looked around, and then entered a crack.

This crack, obviously formed naturally, extends for an extremely long distance, and can even connect to another catastrophe pit in the distance.

It seems that the thunder catastrophe that happened ten thousand years ago was indeed devastating, as can be seen from the trauma of these potholes.

"Little head, you like eating spirit crystals so much, it just comes in handy!"

After entering the crack, Lin Yi released his little head. He knew that his little head was very sensitive to the spirit crystal, but he didn't know if it would have any effect on Lei Jing!

The little head was suspended in mid-air, stretched out his nose, and smelled around, but also looked dazed, as if he didn't feel any breath.

Lin Yi touched the little head's body, and then flew forward, "Then let's look for it together!"

Since the little head didn't sense it, Lin Yi could only probe carefully in the cracks, refusing to let go of every stone, and the natural flying speed was much slower.

After half an hour like this, Lin Yi found nothing but a few ordinary spirit crystals.

Suddenly, the little head screamed "Zhi Zhi", and his eyes shone brightly, as if he finally had a discovery.

Immediately, the little head shook its buttocks, and rushed forward with a speed like electricity.

Lin Yi quickly followed.

In the crack, the little head found another hidden stone hole and slammed into it.

The cave was very big, and Lin Yi quickly flew in, his body just enough to stand up in the cave.

In the blink of an eye, the little head has already flown hundreds of meters away.

In the stone cave, Lin Yi followed the little head and flew for an unknown distance. There were only stones in front of him, and there were stones.

At this moment, the little head suddenly stopped, landed on the nearby stone wall, and yelled.

Lin Yi saw that there was a layer of strange luster on the stone wall, and the aura was compelling.

Sensing carefully, Lin Yi could feel that there was a very strange aura leaking from the stone wall.

The little head waved its two claws, pounced on it, opened its mouth to bite, and bit down a large stone.

Lin Yi immediately took out the Sun Swallowing Sword, and slashed out fiercely, one sword after another, chopping on the stone wall.

The stone inside is indeed very hard. Even if the Sun Swallowing Sword is a heavenly weapon, it can only cut a crack half a meter deep.

With the biting of Lin Yi's sword and the little head, the thick stone wall was finally broken, and then the light became stronger.

Lin Yi took a closer look, but behind the stone wall, there was a large expanse of spirit crystals that radiated like stars.

"Just ordinary spirit crystals?" Lin Yi was slightly disappointed.

But it's better than nothing at all.

Lin Yi stretched out his hands, broke open the stone wall that was in the way, and then grabbed those spirit crystals, and put them into the rings one after another.

At this time, after Lin Yi finished collecting these spirit crystals, he found a dazzling light shining from behind.

Gently moving away the spirit crystal next to it, Lin Yi saw a strange spirit crystal the size of a fist, glowing with strong light, and its size was much larger than ordinary spirit crystals.

Lin Yi stretched out his hand and took this spirit crystal in his hand, it was very heavy, at least several thousand catties.

It's incredible that a fist-sized spirit crystal can actually weigh over a thousand catties.

Then, Lin Yi saw that a tiny lightning flashed in the crystal of the spirit crystal. Although it was very weak, Lin Yi caught it.

Lin Yi's eyes suddenly brightened, "Could it be... Lei Jing!"

Lin Yi immediately became excited, quickly put the thunder crystal into the ring, and then continued to crawl inside.

Sure enough, behind those ordinary spirit crystals, there are many thunder crystals, one after another, as if arranged, very neat, and the rays of light gather together, very dazzling.

The power in the thunder crystal is very strong, but also very fragile, even if it is accidentally bumped, it may explode.

The power of the thunder crystal explosion is a threat even to monks in the Mahayana realm.

For monks of Xuanfu Realm and lower, there is almost no possibility of surviving when a thunder crystal explodes.

Therefore, Lin Yi was very careful, took out the thunder crystals one by one, and put them into the ring.

In the end, Lin Yi obtained 20 pieces of lightning crystals and some negligible ordinary spirit crystals.

Twenty pieces of lightning crystals is definitely an astonishing amount. You must know that most monks in the tribe may not be able to find a single piece of lightning crystals in a busy day. If you are lucky, if you can find one or two, you will be satisfied up.

If you can find five yuan at once, you are lucky.

But when Lin Yi first arrived, he found twenty thunder crystals directly, which was enough to make everyone envious.

Of course, this is all thanks to the little head.

Within a certain range, the small head can sense the existence of all spiritual crystals, which is very sensitive.

And the little head also likes this Lei Jing very much.

After entering the ring, his little head rushed towards those thunder crystals as if he was going crazy from hunger.
