With the ability of a middle-aged man, he didn't look at the distance of two or three hundred meters from the cave opposite, but he was able to catch even the slightest fluctuation of spiritual power as usual.

In his opinion, even if the people of the prefecture-level realm tried their best to suppress the aura, it was impossible to completely hide it, after all, the realm was not enough, and there was nothing to say.

It's just that this time it disappointed him again.

He stood on the top of the hill for a full hour, motionless, like a lifelike statue. But after an hour, the middle-aged man couldn't help but sigh slightly.

"Hey, it seems that I really have a delusion, this person has already left here with the help of some special escape means, forget it, a small person in the prefecture-level realm is not enough to have too much temptation for me, go!"

The middle-aged man finally lost his patience, jumped and flew down the tip of the big tree below, and then, flying along the top of the tree, disappeared into the vast forest in an instant.

Whether he left or not did not have any impact on Jiang Feng's heart, but when he entered the cave, Jiang Feng did not dare to sloppily perform the invisibility technique even in the Thousand Illusion Labyrinth, and used soul transmission to remind the big head and the big spider not to move without permission.

And when the middle-aged man walked out of the cave, Jiang Feng immediately returned to his normal state.

Jiang Feng entered the Thousand Illusions Labyrinth, it was impossible to simply cultivate, there was a Thousand Illusions Labyrinth, where could he not cultivate? The most important thing is that Jiang Feng wanted to refine that small stone ball and become his handy treasure.

Therefore, Jiang Feng now put aside all selfish distractions and immersed himself in the matter of refining the small stone ball.

......

Three days later, a long-tailed broad-billed bird, which was more than half a meter in size, flew into a valley, circled twice in the air, and slowly flew down to the edge of a cave to rest.

Probably flying too long, the long-tailed broad-billed bird was really tired, and it raised its paws to comb its feathers.

It should be said that this cave is good, there is no feces and other dirt left by other birds, and the air here is very good, so it is definitely a great place to build a nest here.

As soon as the long-tailed broad-billed bird decided to make this place a nest, it heard a rattling sound from the cave, and it was startled and hurriedly turned back to look.

I saw that on one side of the stone wall, a lot of broken stones fell, and then an oval stone the size of a fist fell to the ground. Although this stone is unremarkable, all other stones are angular, but this one looks so smooth.

The long-tailed broad-billed bird saw that it was not a bird of prey or something, so it quieted down and did not fly away from the place.

Who knows, a cloud of mist slowly rises from the very reluctant stone, and immediately after, a human appears there. The long-tailed broad-billed bird was frightened and hurriedly flapped its wings and fled from the place.

However, now it could not escape even if it wanted to, and as soon as the man who appeared beckoned at it, a clump of vines sprang up at the feet of the long-tailed broad-billed bird for no apparent reason, and wrapped its legs tightly around it.

The long-tailed broadbill screamed, it knew something was wrong.

At that moment, a cloud of mist emerged from the oval-shaped stone, and a monocular giant that was a head taller than the human just now appeared.

As soon as he saw and caught a long-tailed broad-billed bird, he laughed, "Master, it's great, Xiaoqing and Xiaohei are tired of eating that snake meat all day long, just use this bird to change their appetites!"

The oval-shaped stone is not an ordinary stone, but it is a thousand illusion labyrinths, the two people who came out one after another, in fact, the first one is Jiang Feng, and the second one is not a human being to be precise, he is just a demon who got a chance, and he is attached to the body of a Zhu Qian, which is Jiang Feng's demon pet boss.

The big head was very concerned about this long-tailed broad-billed bird, and as soon as he stepped over, he grabbed the long-tailed broad-billed bird in his hand.

"Haha, thank you master, I'm going to feed those two little brothers. The big head bowed to the river breeze and turned into a cloud of mist and returned to the Thousand Illusions Labyrinth.

Jiang Feng smiled slightly at this and did not say anything.

The retreat was long enough, but it was so short for him.

Fortunately, after several days of continuous refining, it finally succeeded in refining the small stone ball.

No matter how difficult the process was, the result was good, and after refining, he also obtained all the information about the small stone ball. It shouldn't be called a small stone ball anymore, the most standard name is it, Thunder Source Crystal.

Or directly called Lei Yuanjing.

To be precise, it is the crystallization of the thunder source stone, the highest grade of the thunder source stone. Therefore, its function is extremely simple, and the Thunder Source Crystal has all the attributes of the Thunder Source Stone, which is something used to store the power of thunder and lightning.

After refining, at this time, Lei Yuanjing was already very different from the original volume, but it was reduced many times, only the size of a soybean grain.

Don't look at the size reduction, the function will not change. Of course, making it smaller is also conducive to Jiang Feng's carrying, Jiang Feng immediately matched Lei Yuanjing with a ring after refining Lei Yuanjing, and finally set Lei Yuanjing in the ring.

On the finger, the ring is unremarkable, looking like nothing more than a ring set with an ordinary milk-white trash jade.

And Lei Yuanshi can hide its true function on the surface, but it makes Jiang Feng very happy, if Lei Yuanjing is sharp and bright, it will not be troublesome.

Jiang Feng unleashed his thunder eagle wings and flew to the top of the mountain. Just refining the Lei Yuan Crystal is only one of them, and then he has to charge the Lei Yuan Crystal to see how much thunder and lightning power this Lei Yuan Crystal can absorb.

This time, Jiang Feng chose to arrange a lightning guidance array on the top of the mountain, not requiring how good the effect of lightning is, as long as the thunder and lightning are drawn. After all, I don't know much about the capacity of Lei Yuanjing at the moment, so I only used it as the first time to guide the thunder for testing.

The top of the mountain was flattened by the river wind, and a place about a few zhang in size was cleared, and the thunder guidance circle was arranged in the four corners of the mountaintop, and the river wind sat cross-legged in the middle of the circle, waiting for the arrival of thunder and lightning.

After a while, the clouds in the sky began to gather, first with lighter clouds, and then with dark clouds as black as ink.

In the sky, a chaotic wind stirred up the black clouds.

However, the clouds of the two forces began to squeeze each other, collide, and faintly erupted into a dull thunderclap.

This is the premonition of thunder and lightning, and it is also the effect that the lightning guidance circle can achieve.

Finally there was a big reaction, "click"

"Boom"

The sky was dark, thunder and lightning.

As the thunder and lightning in the middle of the dark clouds became more and more dense and intense, finally some lightning struck down from above, marking a trail of silver light.

Jiang Feng was waiting for this, and he immediately raised the ring wearing Lei Yuanjing above his head.
