On a flat ground halfway up the mountain not far from the XIO base, the clear sound of 'ping, ping, ping!' was heard endlessly, and on the green grass, two people with wooden swords were slashing at each other.

Earth's chest rose and fell violently, gulping in the air, his face was covered with beads of sweat, and he kept sliding down his face, and the shirt on his back was almost soaked, clinging to his body.

And Xiang opposite him only had a few drops of sweat on his face, and he was not sweating like the earth, holding the hilt of the wooden sword in his right hand, his eyes were fixed on the earth, his steps and the earth circled, and he couldn't stop saying: "Concentrate on observing the opponent's movements, read his pace, and then rush to the enemy and cut through." ”

"It's easy for you to say..."The earth muttered uncontrollably, the sweat droplets oozing from the palm of his hand soaked the hilt of the sword, and the continuous collision made his right hand numb and almost unable to hold the wooden sword, and his eyes looked at Xiang who was only two or three meters away from each other in a little panic.

After the two of them stared at each other and circled each other twice, Xiang suddenly took a step forward, and the wooden sword in his right hand was raised, slashing at the ground opposite. The earth, which had been watching Xiang's movements, hurriedly raised his sword to block.

However, the hands holding the sword of the earth did not feel the vibration, and before he could react, the wooden sword that Xiang swung suddenly changed its trajectory, and the wrist flipped from a downward slash to a horizontal slash, and the blunt blade of the wooden sword pressed against the belly of the earth. At this time, the wooden sword of the earth was in a posture of blocking the enemy at this time, but unexpectedly, the touch of the hard object from his abdomen made him stunned.

At the same time, Xiang's firm voice came from the ear of the earth: "Remember, don't let your attack intent be so obvious at any time, otherwise you will definitely suffer." With Xiang's voice, the wooden sword in his hand suddenly exerted force, slashing from the abdomen of the earth, and the sudden burst of powerful force made the earth stumble back several steps, and then fell to the ground all of a sudden.

"It hurts!" the earth grinned and clutched his abdomen, feeling the hot pain there, and the slightest movement made it hurt.

Xiang straightened up and immediately raised his hand to wipe the sweat beads from his forehead, bent down slightly and stretched out his left hand to the earth sitting on the ground, pulled the earth up from the ground, and said with a slight smile: "Let's rest first." ”

"Hey!"

The two of them looked at each other and smiled, and then walked to the place where the towel and fresh water were placed on the side, and an extremely small streamer in the sky above their heads flashed, from appearance to disappearance added up to less than 0.1 seconds, and fell straight into a mountain land, and then disappeared into this continuous mountain land.

In the forest at the foot of the mountain, Horned Wing, who was dressed in a linen coat to resist the wind and sand, stood up straight, looked around at the emerald green trees around him, and showed a sense of joy on his face, then reached out and ripped off the slightly tattered linen cloak on his body, and walked towards the mountain in front of him, which was no more than 200 meters high.

"Is it here, is it in the mountain?" said Horned Wing uncertainly, looking at the mountain peak in front of him, after all, it was a message received in another distant universe, and it was already good to be able to find this place.

Then a streamer flew into the sky, and then hit the mountain headlong, rushed directly into the mountain and disappeared, and did not advance for long, the true horned wing felt that the front was empty, and the surrounding rocks had disappeared, and he had come to a huge and incomparably empty hole.

'Whew!'

A pillar of light suddenly appeared in the darkness and boundless darkness, like a sharp sword, splitting through the darkness and illuminating a land of light. However, compared to the surrounding darkness, this pillar of light was too weak, only penetrating more than ten meters of darkness.

True Horn Wing was very surprised to look at this corridor that was seven or eight meters high and four or five meters wide, and the dilapidated bluestone bricks around it showed that this place had existed for a long time, and even the bluestone bricks had been worn out a lot by the years.

As he walked, he looked at the quaint walls around him, and he didn't expect that there was such an ancient building hidden in the mountain, and if it was discovered, it would definitely become a miracle that caused a sensation in the world. After all, it is much more difficult to build such a large complex in the mountains than it is to build it on the ground.

The faint sound of footsteps echoed through the silent corridor, echoing in the darkness, piercing through the thick of the night, and disappearing for a long time. It took more than thirty meters to reach the end of this corridor, dividing into two corridors on the left and right, which made Horn Wing slow down and consider where to go.

The flashlight in his hand shone to the left, and suddenly there was a chilling sound of wind in his ears, which startled Tsubasa Horn, and the muscle memory that the long battle had cultivated made Tsubasa take a step back immediately, and at the same time his body fell backwards, letting the scream brush his face.

The flashlight in the right hand of the True Horn Wing flipped over, and the beam of light that was originally shining in front of it rotated eighty degrees, sweeping past True Horn Wing's face, and at the same time, the tail of the flashlight slammed forward, and immediately hit the attacker's abdomen, causing him to stumble back several steps before stopping.

"Whew!" True Horn Tsubasa struck a blow, and his right hand immediately flipped and swung away, causing the beam of the flashlight to shine in the direction of the attacker, only to see a young man in an orange uniform slamming his back against the wall, clutching his abdomen, his face full of surprise and surprise.

"You're... Auditorium Light?!" True Horn Wing tilted his head slightly, and asked suspiciously, "Why are you here?"

"Senior, this is a long story. Auditorium Hikari smiled bitterly, shook his head slightly, and then straightened up, and told the cause and effect, including the robot that lost to Zeuda and was caught and trapped here, and finally broke free from the chains, and walked around this place in the dark, I don't know how long I have been wandering.

True Horn Wing's originally leisurely face became solemn, and the index finger and middle finger of his right hand unconsciously tapped the shell of the flashlight, and nodded a little clearly: "It seems that the call is not groundless, but it is because you feel the danger, so you called me?"

"Call?" The auditorium looked at the True Horn Wing for some reason, and the True Horn Wing nodded, and then explained: "Originally, I was in another universe and heard an unknown call from this planet, so I found here, but I haven't found where the source of the call is?"
