Leaving Source City and walking on the forest path, a mysterious voice suddenly sounded in Ji Yuan's mind, saying that he sensed a trace of energy fluctuation reaction, and it was very likely that it was a mage evolution stone, or an evolution stone with a very high energy purity attribute.

He must not abandon the unexpected appearance of treasures, and under the guidance of the mysterious voice, he walked all the way through, forests, rivers, waterfalls, and even "swamps", and finally came to a cave on a rocky mountain.

Ji Yuan glanced at the cave, frowned and asked in his heart, "Are you sure?" A trace of energy fluctuation sensed was diffused from this place. ”

In front of him, the cave that looked dark and silent, slightly taller than a human, he didn't feel fear, but felt that entering this small space, if there was really any accident, the Tyrannosaurus would be greatly restricted, and there would be no way to exert its strength at all.

"I can clearly feel that the source of energy is floating out of this cavern, and in the deepest part of it, there is a hidden existence that can shield my perception."

Is it possible to block its "perceived" existence?

Ji Yuan still recognized the strength of the owner of the mysterious voice very much in his heart, although it was the reason for the distance, but even its perception could be shielded, proving that there must be a certain danger inside.

But......

Crises always coexist with opportunities, and Ji Yuan didn't know how many times he had experienced it since he left the Silver Academy, and he was still very interested in breaking into this cave.

Now that he has decided, Ji Yuan took out a Poké Ball from his waist, pressed the middle button, released the Pokémon inside, and said, "Wait a minute, I want to enter inside, and then I will trouble you to lead the way in front to defend me from the danger." ”

The Pokémon he released was mostly black in its body, and it looked more like a dog, with large and curved white horns on its head. The orange snout is prominent, and the tip is a black nose with two inconspicuous external teeth.

The neck and back are surrounded by light gray bony objects, including three on the back. There is a grayish-white circular protrusion in the center of the neck. The abdomen has the same color as the muzzle, the lower limbs have three toes, sharp claws outstretching, two bones on the ankles, and a long tail that resembles an inverted triangle.

It is the Dairubi Evolved Black Ruga, who attacked Rin New Town with King Nido at that time, and because of his outstanding strength, he was the first to be targeted by Ji Yuan, and then defeated and subdued by him.

The Heruga may look vicious on the outside, but it has the characteristic that most dogs have, that is, they are very loyal to their owners, even if they are forcibly subdued.

"Hey~~Hey~~~" After hearing its command, Heiluga did not show resistance, but shouted twice on the spot, and began to lower his head and sniff the ground, and walked directly into the cave.

Seeing it walk in, Ji Yuan took out a flashlight, and then followed in, his eyes kept strafing around, and he was always on alert.

Almost every two steps, Heruga sniffed the ground with his nose or pricked up his ears to hear for movement in the distance, looking very dutiful.

The cave was dark, except for the flashlight in his hand, which radiated the pillar of light, there was almost no light to be seen, and even the sound was only footsteps, and there was no sound coming out, and it felt like it was being enclosed, which made people feel irritable.

After walking with Heilujia for a while, he was always moving forward in the depths, which made Ji Yuan feel in his heart that it was not a good way to continue looking for it so aimlessly, and he asked the mysterious voice: "Do you feel any specific location there?" ”

"I can only feel it now, the closer we get to the front, the more dense the energy aura will become, if it is in my heyday, I can easily use 'teleportation' to take you there, but unfortunately the injury is too serious now, and even the breath must be hidden."

"If so...... Can we just keep going? Ji Yuan responded silently in his heart and continued to walk forward.

"Hey Lu ~~~~~"

Not long after walking, Heiruga seemed to feel something, bared his teeth and stopped, glaring at the front and screaming loudly.

"Hmm......" Seeing its appearance, Ji Yuan guessed in his heart that something was leaning towards them, so he moved to the right vigilantly.

Crash! Crash! Crash!

It wasn't long before even he heard a movement, as if some kind of creature was flapping its wings, flying towards their location.

"Heruga, don't act rashly, come to my side first." Since Ji Yuan was not sure whether the movements in front of him were suspicious of him, he could only get close to the stone wall next to him, holding the Tyrannosaurus Poke Ball in his hand to prevent any accidents.

"Hey, hey—"

As for his own trainer's words, Heiruga would of course obey, and with a light leap towards the right position, he jumped to the position in front of Ji Yuan, and made a fierce and vicious expression ready to attack.

It didn't take long for a shrill "Boom-" scream, mixed with the sound of wings flapping, to keep coming this way.

Could this be it?

Hearing this piercing scream, Ji Yuan felt very familiar, like a magical treasure that he could often see when he entered the dark area. Seashell.

Under the light of the first flashlight, bat-like figures began to appear in front of them, one, two, gradually becoming more and more numerous, as if covering the sky and the sun, making a "squeal" scream, like they flew here in groups.

"Is it really a swarm of sonic bats? The Black Ruga unleashes your momentum, but don't attack them. Ji Yuan immediately saw their identities, and hurriedly gave an order like Hei Lujia.

The sonic bat is a very common Pokémon, which usually inhabits dark environments in groups, such as caves, although it has four fangs in its mouth, and occasionally sucks the blood of other creatures and stocks, as long as it shows a little momentum, it does not dare to attack each other easily until it is completely provoked

"Hey~~~~"

Heilu bent his limbs forward, and screamed in a low tone, exuding a very dangerous aura all over his body.

Although supersonic bats do not have eyes, they are able to constantly emit "ultrasound" waves from their mouths, and can easily distinguish all obstacles around them in extreme darkness.

Feeling the momentum emanating from Heiruga, the supersonic bats did not provoke the two living creatures in front of them, but collectively bypassed them, continued to flap their two small wings, and flew quickly forward.

I don't know how long it took, all the supersonic bats flew away, and Ji Yuan finally breathed a sigh of relief in his heart, although their strength was not strong, but such a large group of people meeting in this narrow cave would indeed involuntarily give people a kind of deterrent.
