In fact, when discovering the truth about the transformation of the dream region, Du Mu expected that this day would come sooner or later.

As the Hunters and Eroders have been wiped out, the fog has vanished, and the fog balls have degenerated into their original form of Nightmare Lair, and the transformation of this dream region has been gradually reversed.

After the last wisp of mist was absorbed, the mountain grassland finally returned to its original state, and the light film surrounding the grassland border disappeared, and the remaining tribes were able to get in touch with the outside world.

And he also had a faint premonition in his heart, and immediately realized that he was afraid that he would soon leave this world, and wake up in reality, and wait until the next time he entered the dream realm, he was afraid that he would never be able to enter the mountain grassland again.

However, Du Mu didn't have much regret about this, the benefits he had obtained in the Mountain Ancient Grassland had far exceeded his previous expectations, in addition to the four movable nightmare nests, there were also many holy fruits.

After that, he traded hundreds of holy fruits with Slash Bei and other tribes, and except for some of them that were given to Luo Shen and Luo Yao in reality, the rest were all lying in the dimensional house.

Without entering the tribe, after Du Mu explained to Yanwei and Xiaoye on the spot that he was about to leave this world, he turned around and left, leaving everyone looking at his back in shock and confusion.

For Du Mu, the mountain ancient grassland is just a transit station, on the contrary, he is only a passerby to this grassland, and the two have not even established a deep connection, so when he leaves, he seems very indifferent.

The next night, returning to the Colosseum of the Tower of White, Du Mu found that the halo in the cave had disappeared.

“...... Now it's time to continue exploring the Tower of White. ”

Shaking his head, Du Mu left the Colosseum and returned to the 49th floor.

At present, except for the opera hall on the 47th floor, there is only 50 floors above the 50th floor that has not been explored.

The opera hall on the 47th floor was immediately excluded by Du Mu, who was still not sure how to deal with the girls and many monsters there.

"Then we have to keep exploring. ”

Walking up the stone stairs, Du Mu soon arrived in front of the door on the 50th floor.

Standing in front of the door and listening intently for a while, he didn't hear any strange sounds, and then he put his hand on the stone door and slowly pushed the heavy door open.

Bang!

The dull sound of the stone shaft turning tore through the silence in the blink of an eye, shaking the dust on the ground not far away, and immediately a puff of dust shook up behind the door.

Du Mu stood up straight, slowly stepped into the door, raised his arm, and the huge force suddenly set off a strong wind pressure, blowing away the dust in front of him, revealing the situation behind him.

What you see is a spacious rotunda, most of the towers in the Holy White Tower are similar architectural styles, Du Mu has seen it many times, he is very familiar with it, and he is not surprised to see this, and his eyes sweep to see all the scenes in the large round hall.

The hall was large, but empty, with no decorations or furniture, and the floor was covered with a thick layer of dust, so it was clear that no one had been here for a long time.

However, all of this was insignificant in Du Mu's eyes, and in the depths of the hall, a huge stone door that almost touched the dome immediately attracted his attention.

The stone door is huge and incomparable, and it is engraved with complicated and exquisite patterns, which seems to be irregular, but there is a sense of majesty that is breathtaking, and Du Mu took a lot of effort to break free from the stone door.

"It's weird!" Pastor Du let out a sigh and frowned slightly.

You must know that in the exercise of looking at the portrait girl, his will attribute has been steadily improving, and now it is extremely close to the C-level, it stands to reason that the higher the will, the stronger the resistance and immunity in the spirit, and it will never be so much that you almost lose your mind when you look at some patterns.

Thinking of this, Du Mu couldn't help but secretly mention that he was very cautious and cautiously walked towards the stone gate.

In addition to the strange stone door, there are two huge statues on each side of the door, which seem to be carved from stone, all blue and white, and as they get closer, a simple and majestic aura comes to the face.

However, the two statues seem to have experienced a heavy blow, the upper part has long been turned into rubble and sprinkled on the ground around it, and the only remaining lower part is also full of cracks, which can be vaguely seen to resemble human-like legs and a small half of the waist, as well as a sharp stone chip inserted into the ground that is suspected to be a broken blade of a giant sword.

However, even if it is incomplete, the remaining part of the statue alone is more than ten meters high, which shows how majestic and huge the volume must have reached in the complete state.

But even a strange nightmare creature can't be resurrected if its body is shattered like this, right?

Du Mu glanced at the two statues, secretly breathed a sigh of relief in his heart, and gritted his teeth and slowly came to the door under the pressure of the continuous rush like a tide.

He stretched out his hands and pressed his hands on the door, but the stone door did not move.

Du Mu's brows frowned slightly, his mind moved slightly, and his left and right upper arms bulged high at the same time, and then he exerted his strength again.

This time Shimen finally reacted, but it only trembled slightly, and there was no movement except for a large amount of dust, but Du Mu was sprinkled with a dusty face.

Phew!

Spit out the dust in his mouth, Du Mu raised his head and looked helplessly at the stone door in front of him, and then hurriedly retracted his gaze, and a trace of helplessness suddenly arose in his heart.

In addition to the inexplicable strong sense of oppression of the spirit, the stone door in front of him is also heavy like a mountain.

You must know that after blessing Gang Liluo, his strength has reached a terrifying level, even if there is a ten-ton bus in front of him, he pushed it so hard just now, I am afraid that he will not immediately fall out, but Shimen only trembled, and the heaviness was almost desperate.

Du Mu withdrew his arm, took a few steps back, his eyes passed by the statues on both sides of the stone gate, and a thought suddenly flashed in his mind.

If these two statues hadn't been damaged by some kind of creature, they might have been in charge of pushing open the heavy door, since their size alone would have been so strong.

Sighing lightly, Du Mu turned around and left the hall.

For now, it seemed that he would not be able to continue exploring until he had a way to push open the stone door.

And at the moment, the only effective way is to increase your strength and increase the skill level of Gangliluo until you have enough strength to try it again.

However, without the Nightmare Energy, it would be very difficult for him to improve his strength quickly.

"It seems that we have to start from reality and see if there is a way to quickly increase our strength!"

The next day, when Du Mu finished his daily cultivation and was about to go to Qingteng Bar, he received a call from Guo Xiaojun.

As soon as it was connected, Guo Xiaojun's cheerful and funny voice came from the other end.

"Hey, senior, are you free tonight?"
