It was a huge underground space, and the cold moonlight shot down the shattered void, bringing a little light to the pitch black underground. The ground was still full of quicksand, but under the cold moonlight, it took on a cold aqua blue.

The leader stood in a place of light, as if a cone of light shone on her body, the red cloak, the golden runes, and the scarf that danced in the wind like a ribbon showed a strange beauty in the cold moonlight.

The leader turned his head slightly, tilted his head towards Li Mu, and then continued to walk forward.

It was littered with the wreckage of shattered war machines, massive machines half-buried in quicksand, and occasionally a few rune ribbons crept by.

There were more and more wreckage, and there were more and more red rune ribbons, and suddenly, Li Mu entered a huge space, which was full of all kinds of machines, and countless rune ribbons came out of the cracks of the machines, and there was a little blue light in the air, and there were several jellyfish-like creatures composed of rune ribbons floating in the air.

The leader flew into the air and injected the jellyfish with rune energy, and the jellyfish let out a cheerful cry, and the golden runes shone brightly, adding a bright color to the cold space.

Seeing this, Li Mu and Shuang'er also hurriedly went up to help, and released all the runes in the machine, at this time they were no longer novices who knew nothing, and they gradually mastered the technique of releasing rune energy.

After releasing all the rune ribbons here, Li Mu followed the lead and continued to walk down the pit to the depths.

In the depths of the tunnel, Li Mu saw a wreckage as huge as a cobra's head.

"Could this be the war machines depicted in the murals? Is this the kind of war machine manufacturing plant? Li Mu's gaze looked into the distance, and on both sides of the huge tunnel stood huge war machines like snakes with eyes, and the cold metal body exuded a cold light.

"Looks like something bad is going to happen." Li Mu looked at these huge war machines with some surprise and thought silently.

Ahead, a red kite-like rune ribbon flew through the air. Rumble! Suddenly, there was an explosion, and a huge war machine emerged from the earth, biting the kite rune ribbon that was floating in the air. The gigantic war machine was like a serpent, its head glowing with magical light, and its huge body fluttering in the air flexibly.

The giant war machine roamed the air for a moment, the light above its head flickering, as if searching for any other creatures around.

Li Mu and the others hid behind a ruin, waiting for this huge war machine to slowly float over.

"You can't be cowardly, hurry up." This is what Li Mu thinks in his heart. In normal times, it might not be a problem for him to beat a few of these war machines, but now that his entire body is sealed, it is simply self-defeating to fight against these behemoths.

So he decisively followed the leader into a small road.

A huge shadow swam nearby, Li Mu saw the other party's huge figure reflected on the wall several times, but maybe the other party's search accuracy was not high enough, maybe the leader was very familiar with this area, and they passed by this huge war machine several times.

After a few explorations, Li Mu gradually saw the attack pattern of these war machines, they would use the searchlight-like thing above their heads to scan the surrounding things, as long as they found something with energy fluctuations, the light would turn red, and then the huge war machine would quickly pounce on it, and then bite it to pieces.

Along the way, Li Mu and the others followed the surrounding ruins and carefully dodged the war machines that were constantly patrolling the passages. Finally, Li Mu and the others came to the top of a slope, which was a sand-skiing terrain, and several huge war machines were patrolling along the way, scanning back and forth. At the lower end of the slope was a huge rune stele, a hundred times larger than a war machine, and golden runes were carved on the stele, shining brightly, illuminating the entire passage.

"It seems that I can't hide from it." Li Mu looked at this terrain and thought.

At this time, the leader kicked Li Mu, and then rushed straight over.

"This guy!" Seeing this, Li Mu shook his head helplessly, and also rushed over. Although he also knew that the other party was right to do this, he could only rush straight over when he couldn't dodge. However, he was still a little dissatisfied with the other party's approach. Can't you just express it well?

Several people slid down the slope at a rapid pace. The blue light of a huge steel monster scanned several of them, and the blue light above their heads turned blood red, and the huge steel monster quickly turned and rushed towards them.

Several people suddenly sped up, urging the power of the runes to the extreme. As they got closer, they got closer and closer to the golden stele. There was a loud bang. Li Mu looked back, and it turned out that the huge war machine had hit a layer of golden light. A pale golden glow guarded the stone monument. At this time, they were already standing in front of the stone monument.

The huge black stone tablet was engraved with golden runes, exuding a faint golden light, if possible, Li Muzhen wanted to rub these runes down and study them well, but unfortunately he could only think about this wish.

There was a small triangular mural under the huge stone stele, and after being familiar with the energy, Li Mu and the others came to this white space again. At this moment, they stood next to the tall white-robed man, facing in the same direction, and at the end of the gaze, a mountain of light stood at the end of the horizon.

Li Mu looked at the tall white-robed man suspiciously, and the other party just stared at him with his eyes, still silent.

A wave of energy spread out from the other party's body, and the mural slowly unfolded again.

As the war continued, more and more cloaked humans died, and the sand covered their remains, as well as the cities that had long been empty, leaving only a few tombstones to sit on the sand. Proof that they once existed.

There were still a lot of runes floating in the deep sky, as if everything had returned to its original state, until a rune fell down in the sky as a meteor. Descending to the top of a sand dune, he slowly transformed into a man in a red cloak......

"I see, is that so? Born from the runes and back into the runes, it's all part of the cycle, is this the whole journey of this race? While Li Mu was thinking, a huge hollow gate appeared in front of Li Mu, and a passage appeared in front of them.

At the end of the tunnel, there is a golden gate.
