In order to avoid being discovered, especially for that mysterious guy like an assassin, Xin Yuan did not follow very closely, but deliberately kept a very extreme distance to track.

So when he cautiously came to the entrance to a tunnel beneath an angel statue, Parrion had already entered the tunnel and walked far away, and even if he listened carefully, he couldn't hear any movement.

The statue is located in a sparse forest on the side of the road, which is overgrown with weeds half a man tall, and if you don't get close, you can't really see the entrance to the tunnel.

Beneath the broken statue, a swarthy hole in the ground was exposed diagonally in the grass, surrounded by vines and grasses, and when you got closer, you could feel a stream of air gushing out with a lot colder than the outside.

He lowered his head, and suddenly found some vague footprints on the grass at the entrance of the cave, some of which had been trampled down and had not yet fully rebounded.

After thinking about it for a while, Xin Yuan decided to go down.

From the words that he had overheard from Parleon, this core area was divided into several floors, and the first garden he was in was supposed to be in Parion's mouth, and it was not a safe place, and it was likely to be very dangerous with the passage of time, and he could not stay longer.

In addition, Parrion obviously concealed a lot of information before, he actually knew a lot about this place, and it was likely that he had obtained a lot of important information from Silver Sands Island or some other place he had explored before, so whether he wanted to leave here or what he wanted to gain from this ruin, following him was the best choice now.

The passage was dark, but unusually dry, with no standing water, and the air flowing through it was not humid.

Xin Yuan walked cautiously, and there was a faint sound of broken footsteps under his feet.

As he advanced, it was evident that the air was getting colder and the passage wider.

It didn't take long for him to discover the cause of the situation.

After walking through the tunnels for more than twenty minutes, he arrived at a circular hall. Different from the pitch-black passage in front of him, the walls of the hall were painted with some kind of glittering silver paint, which made the entire hall glow with a layer of silver shimmer, so that he could see at a glance a facility similar to a cold storage located in the corner of the hall on the left-hand side, a crack in the huge steel warehouse door, and some pale black gas was faintly escaping, and he could feel a biting chill when he got closer, but it would not condense and freeze. He sensed that this black gas contained a strange energy fluctuation, and the water vapor in the air would quietly disappear when it came into contact with it, as if it had been neutralized.

"This should be a warehouse, right?"

Xin Yuan thought about it, and it seemed that this guess was more in line with the real situation.

Although he might be able to get some resources from here, he didn't stop and continued to track Parleon along the corridor behind him. Before he found a way to leave safely, taking more things would only add more funeral goods to himself, and since Parleon didn't stay here longer, it meant that this place was of little value to him, and Xin Yuan naturally had no interest in staying here to pick up the bits and pieces that others didn't want, and the gains outweighed the losses.

Further down the corridor at the back of the hall, it seemed that Paleon was a little far away from the front of him, and he had to speed up a bit.

The environment of the passage began to get complicated, like a spider's web, it began to fork, and there were corners and junctions everywhere, but there was no room or anything like that. It was also becoming more and more difficult to track, and each time I had to carefully identify the bifurcation for a while, and even missed it twice, but fortunately I found the turn in time, and I barely managed to keep up with the traces left in front of me again.

In this case, he had to start risking himself to take out his light stick and run through the corridor quickly, otherwise it would be terrible if he really got lost in this labyrinthine underground passage.

After rushing forward for more than ten minutes, Xin Yuan finally found a stone door that was half-open. Behind the door was a staircase that extended downward, and streams of cold air continued to pour out of the passage.

He stood in front of the entrance, crouched down, and took a closer look at the ground. On the dusty ground, some messy footprints overlapped, not left by the same person.

It seems that the big army has caught up.

Xin Yuan breathed a sigh of relief and finally caught up.

Passing through the stone door, he continued along the stairs.

Just walked out not much.

There was a buzz, and a slight tremor suddenly came from the stairs below, as if something was shaking the passage in the distance.

The tremors lasted for two or three minutes before slowly subsiding.

Xin Yuan stood in place, closed his eyes and felt the direction of the vibration, and when the vibration was over, he had already roughly judged the direction, and directly rushed forward a few steps, turned into the passage closest to that side, and increased his speed.

The passages here are almost identical, except for the stone walls and stone walls, there is hardly any difference to be seen.

Fortunately, those vibrations would occur every ten minutes or so, so that Xin Yuan would not be dizzy by such a passage.

He turned more than ten corners one after another along the way, changed several passages, and saw that a different passage finally appeared at the end of a stone wall, and the stone wall inside was no longer monotonous gray and white, but painted with dense murals, not only on the walls, but also on the ceiling and floor.

Looking closely, the colors used on the mural are very rich, and the main body on it is a bit like a flower plant, but with long legs and hands, slender and long, the proportions are very strange, and at a rough glance it is quite like a stickman's style, they grasp the legs of the previous one one by one, forming a circle, surrounding a round ball in the middle, as if performing some kind of ritual.

Not long after advancing through the mural passage, I entered a small room, and the walls of the room continued the style of the previous passage, and were painted with murals of those flower figures.

Surrounded by these murals, there is a black square stone door on the wall of the room, in the front, on the left, and on the right, and then I turn my head and look at the passage that enters, and the same.

The stone door on the right had been smashed, and large pieces of rubble had fallen to the ground. Xin Yuan leaned over and took a look, there was a lot of dust accumulated on these gravels, obviously it had been a long time since the door was smashed, there were also chaotic footsteps next to it, and some movement could be faintly heard inside, it seemed that the people in front had also chosen this passage, and it was not far away.

Xin Yuan restrained his breath, lightened his feet, and walked in.

Crashing!

There was another muffled sound, this time not only much clearer, but also faintly mixed with the roar of people.

Xin Yuan crossed the stone gate and moved quickly along the passage, the hidden talent of the Bloody Hunter under the fluctuation of the source fire was fully exerted, so that his movements barely left any traces on the spiritual and material levels, agile and quiet.

After a few minutes of continuing on the road, the voices came more and more clearly and more frequently, the cries and noises of the battle.

In this case, his movements are more light and his attention to the surrounding situation is more cautious.

Suddenly, his expression moved, and a creepy feeling came to his mind, and he stood against the wall with his fierce body, trying to stick himself completely against the wall, leaving no gaps, as if he had become a part of the mural, motionless.

Sou!

A dark shadow swept in front of him, and scurried into the darkness in front of him with great speed, and it was a tree root that looked like several giant pythons were entwined together.

In the next moment, there were terrible screams and even more fierce roars in front of them.
