After seeing the flowers in the desert, Li Mu followed the leader and embarked on the journey again. They continued their previous process, searching for runes, freeing the imprisoned kite-like rune silk, and making their way to the mountain one step at a time.

The pale pink desert glowed with starlight in the sunlight, flying and sliding down between the sand dunes, followed by a large number of red rune kites, and two of the same companions, although they could not communicate in words, Li Mu felt that this trip did not seem to be so lonely.

I don't know how long it took, Li Mu and the others came to a high tower in the desert, and the green light flashed in the tower, and there was a rumbling sound. Li Mu and the others slowly flew to the top of the tower. At the top of the tower there is also a triangular fresco. The leader lit up the rune stone pillar, and a familiar white light enveloped everyone inside.

Still the familiar white-robed figure, the mural once again unfolded along the previous scene, more and more buildings, but fewer and fewer plants, those places that were originally plants were replaced by buildings rising from the ground, more and more rune ribbons were sent into the machine to provide energy for more and more buildings. There are more and more buildings, more and more complex styles, and higher and higher heights, all the way to the sky.

This scene reminded Li Mu of a song, "Climb Up, Forward, High Tower" in that song also depicts a similar world, people built a tower that reaches to the sky, all the way to the top of the clouds, people in order to climb up exhaust long queues, the first layer of the tower is paradise, the second layer is the downtown area, the third layer is heaven...... People think that the higher the building, the more happiness it gets, so they keep climbing upwards and building upwards, and the towers become smaller and taller, and eventually the overwhelmed towers collapse and bury everything......

"Is it the same with this world?" Li Mu guessed.

After the mural was displayed here, it stopped, and as the white light faded, Li Mu and the others returned to the top of the tower again.

The leader slowly stood up, she looked up at the sky, at this time, the sun slowly fell towards the mountain, the leader suddenly turned around, smiled at Li Mu, although he couldn't see his face, but the other party's eyes had been bent into a crescent moon.

The leader spun around and flew up, then rushed down the hill. Li Mu didn't know what the other party was going to do, so he also jumped down.

Below the tower is a huge landslide, a series of quicksand, under the light of the setting sun, turning out a faint golden light, black shadows and golden light intertwined, forming a beautiful picture.

Li Mu and the others puffed up their cloaks and slid down the huge landslide, surrounded by human buildings that were mostly buried by yellow sand. Looking at the various buildings next to him quickly sweeping backwards, Li Mu felt as if he was shuttling through a time and space tunnel, and the wreckage of all the buildings around him seemed to be a microcosm of the past time. He is walking in a civilized past, appreciating the beauty of its past.

Continuing to slide downward, Li Mu followed the slide formed by quicksand into a huge corridor, the corridor is long and deep, and the tall columns make a tall dome, the sunset is beside it, the partner is on the side, and the golden light reflects the long figure.

Li Mu looked to the side, outside the corridor were the remains of buildings, the mountains in the distance were still dazzling in the reflection of the setting sun, countless red ribbons flew in the sky, and a touch of sunset afterglow outlined a layer of gold for this one......

Perhaps, this is the most beautiful scenery in the world......

Li Mu thought so.

The ramp continued to go down, and Li Mu and the others also continued to slide down, the sky was getting darker and darker, and the light and shadow were intertwined, slowly blending into the darkness together.

Suddenly, a cliff appeared in front of him, Li Mugang wanted to remind the leader to pay attention, but found that the other party did not slow down but accelerated his speed, rushed straight out, stretched his body in the air, and then slowly fell down under the light of the rune brilliance.

Seeing this, Li Mu also jumped down, anyway, the other party wouldn't harm himself, since the other party didn't slow down, he must have his own considerations for jumping all the time, anyway, there was no way to ask, just do it.

It was a huge pit, and the bottom of the pit was a little dark, which was in great contrast to the beautiful scenery in the eve sun.

At the bottom of the deep pit, Li Mu and Shuang'er came to the side of the leader together, and the leader suddenly ran towards a corner, and Li Mu hurriedly chased after him. In this corner, they saw a mural again, which appeared to show two groups of people in cloaks fighting over some red rune ribbons.

Li Mu had a bad feeling, and when the resources gradually became scarce, the remaining people began to fight for more resources, which is usually the source of war.

Perhaps in order to verify Li Mu's guess, in the center of the deep pit, they found a triangular mural again, and after activating the mural, they saw the familiar figure again, only this time, this tall figure was facing them sideways.

The mural unfolded again, the red rune ribbon slowly disappeared, the energy became less and less, the lights of the building began to go out one by one, and two people wearing rune cloaks tore the rune ribbon in half in order to compete for the remaining rune ribbon, and the dispute began.

Some snake-like weapons appeared on the murals, laser-like things were emitted from these snake-like war machines, a large number of buildings were destroyed, a large number of people were killed, explosions occurred in the city, and the originally prosperous civilization was plunged into the flames of war, gradually turning into a pile of ruins.

"Perhaps, this is the origin of those ruins and tombstones I encountered before." Li Mu sighed in his heart. Greed and wanton demand are often the beginning of destruction. Countless civilizations have fallen to the struggle for resources and interests. In fact, every war is an internal friction, which is reducing the chances of this civilization to move to a higher level, but the rune civilization is a little more thorough......

The mural slowly closed, the white light dissipated, and a hollow gate appeared behind the triangular mural, and the gate slowly opened, and a long corridor appeared again, but this long corridor was deep and long, and the opposite side was no longer a bright gate, but a dark ......

Li Mu and the leader slowly stood up and took steps towards the boundless depth.
