The Tower of the White Tree, the 46th floor of the Colosseum.

As soon as he stepped on the hard field paved with boulders, Du Mu heard a crisp howl in his ears, and when he turned his head, he saw that a little dog with snow-white hair and a delicate body was sticking out his tongue and rushing towards him.

"You're still here, little one. Du Mu looked at the scene in front of him with a dumb smile, raised his foot and lightly tapped the puppy, and a doubtful thought suddenly flashed in his mind.

Anyway, what does this guy eat for so many days?

It doesn't seem to have seen any food in the Colosseum, so could it be that it doesn't need to eat?

Glancing at the puppy that was rubbing against the leg of his trousers, Du Mu shook his head and walked towards the first stone gate on the right.

After passing through the dim passage and arriving at the cave**, Du Mu immediately cast his eyes on the halo in the depths of the corner.

As I had seen last time, the halo was still there, the surface was stagnant and unchanged.

Standing in front of the halo and pondering for a moment, Mu Chang Du let out a sigh, but finally did not choose to enter inside.

With his current strength, it would not be difficult to deal with the erosor with a combat power of more than 6,000, but who knows if there is only one eroper on the other side of the halo?

If he runs out of one end again, then he can only run away, and if he exceeds two ends, his life will even be in danger.

To be on the safe side, Du Mu decided to wait for his strength to improve before exploring, anyway, the Holy White Tower has not yet been explored, so there is no need to rush to find a new dream area.

Leaving the cave, Du Mu came to the second stone door on the right, looked at the two-finger-thick railing on the iron fence, his body sank slightly, and he entered a state of concentration in an instant, and then swung his sword and slashed, and instantly saw several bright sword lights passing by, and the iron fence clicked, broken into several pieces and scattered on the ground.

After dozens of battles during this time, Du Mu's mastery of the 'breath of all things' has become more and more proficient, and now he can enter a state of concentration anytime and anywhere, and his combat power has improved a lot.

Behind the second stone door was also a dim and deserted cave, with nothing but some rotten bones, and no new halo, which made Du Mu quite disappointed.

Next, he explored the remaining six stone doors one by one, but unfortunately there was still no new discovery, so he had no choice but to leave and head towards the next tower floor.

To Du Mu's surprise, as soon as he arrived on the 47th floor, he heard a faint sound behind the closed stone door.

Du Mu's expression moved, and he hurriedly lightened his steps, cautiously approached the stone gate, listened attentively, and after a while, a strange look appeared on his face.

The voice...... Seems to be singing?

Song?

Du Mu raised his eyebrows, and couldn't help but feel a strong curiosity in his heart, it was too strange for a singing voice to appear in this situation.

"But considering that the 41st and 50th floors are all relaxation areas, it's not too surprising that there is a place to sing. ”

Although it is difficult to associate the White Tower with this.

After listening for a long time, Du Mu slowly straightened up, and the gray mist emerged from the surface of his body, condensing into armor to cover his body in a blink of an eye, and then the Dark Chaser also appeared in the palm of his hand in an instant.

After doing all this, he reached out and pressed against the stone door, mustering up his strength to slowly push the door open.

Bang!

The door shaft rotated, making a dull sound, which should have been deafening, but at the moment when the stone door opened, it was drowned in the sound of the tide surging like a sea tide.

It was a melodious and melodious singing.

Sometimes it turns gracefully, like the gurgling water of a mountain stream, sometimes it is passionate, like the rolling waves of the sea, which makes people involuntarily follow the ups and downs of the song, echoing back and forth several times, and has been dispersed to distant places.

Du Mu almost beat his soul hard before he woke up from the distraction caused by the singing, only to feel a cold air rushing up his back.

What kind of weird singing is this? He almost fell into it, and he didn't know what would happen if he got lost in the song?

The head was faintly still a little heavy, Du Mu secretly bit the tip of his tongue when he saw this, and in addition to the severe pain, the whole person suddenly felt refreshed.

"Gray Dream's isolation doesn't seem to have any effect on this song!"

Du Mu became more and more vigilant in his heart, and suddenly pushed the entire stone door open, and the scene behind the door was finally completely presented in front of him.

It's actually a huge indoor theater.

The dome roof, the stout stone pillars of four or five people, the wide stage in the center, and the white marble seats that surround it all reflect the prosperity of this theater.

However, the mottled marks on the walls and the dust on the floor also show the dilapidated state of the theater today.

However, these were not enough to attract Du Mu's attention, and what shocked him was that the spacious theater was actually full of people on hundreds of marble seats!

No, that's not human or not.

Although they have a human-like appearance, they have no corresponding skin and facial features, as if they have kneaded a slow-flowing gray stream of water into a human form, which is very terrifying.

The marble seats were circled around the stage, and the humanoid monsters sat motionless on their seats, staring intently at the stage.

Du Mu followed their 'line of sight', and his gaze couldn't help but stare at them.

In the center of the wide stage, a young girl in fiery red armor was singing loudly.

The girl had beautiful blonde curly hair, her skin was as white as snow, her eyes were wrinkled and shining like light golden jewels, and her small cherry lips were slightly open and closed, and beautiful notes and melodies floated from them.

The fiery red armor is lighter and thinner than Hilson's and Carol's, but it is also more close-fitting, outlining the graceful posture to the fullest.

There is no doubt that this is a very beautiful girl.

Her looks, like her singing, have a strange charm that makes it easy to fall into them.

Du Mu quickly sensed that something was wrong, and took his eyes off the girl with difficulty, and couldn't help but secretly chill in his heart.

"Is this girl also a knight?" Du Mu's mind raced, and his mind quickly recalled the contents of the diary he had read before, but he never found any record of a knight with a beautiful singing voice.

However, the diary is limited in content, so it is not surprising that there are no knights who are not recorded.

Du Mu frowned, looked around, and found that the location of the stone door was exactly in the middle of the marble seat, and there were humanoid creatures on the left and right sides.

He immediately activated the probe, but no data appeared in his field of vision.

"Is it an 'inactive' nightmare creature again......"

Looking up at the girl on the stage, the same is true.

After hesitating for a moment, Du Mu decided to test it, so he grasped the Dark Chaser tightly and resolutely stepped into the stone gate.

In the next second, his eyes flickered, and by the time his vision was clear again, the scenery in front of him had changed greatly.

But he stood on the stage!
