Everything seemed so unbelievable, but to Lei Ao, it made sense.

As he thought of this, Lei Ao gradually calmed down. Immortals were only legends; it was unknown whether or not there were any in the world. However, Lei Ao knew that there was another existence in this world that was no weaker than an immortal — a Qi warrior.

When he was young, Lei Ao had heard a lot of things about him from Mr. Book telling. He knew that they were a bunch of cultivators who pursued the heavens, seeking eternal life. He might not be able to compare to an immortal, but he could easily move mountains and fill the seas while soaring through the skies.

This was not a legend, this was a real existence. Lei Ao once again sized up the surrounding environment. To be able to create such a strange scene, if it wasn't naturally formed, then there would be no other explanation other than the Practitioner.

"Could it be that I coincidentally entered a Qi warrior's cultivation cave?"

Lei Ao muttered a few sentences. Once he thought of that powerful existence, his will to survive was activated. He didn't sit on the ground and wait for death. He walked along the canyon path, hoping to find the exit.

The canyon was very long, and Lei Ao patiently and patiently groped his way forward. Being lonely in the underground river for a year, was there still a need for this little bit of time? He only hoped that this canyon wasn't like the underground river and let him go for a year.

"HOWL ~ ~"

Suddenly, a heaven-shaking roar sounded out, knocking the unprepared Lei Ao to the ground. The roar went straight to his soul through his eardrums, causing Lei Ao to tremble uncontrollably. After hearing the roar, the power in his body quickly disappeared, and his legs began to tremble. In the end, he could not even barely stand.

Gurgle … Lei Ao swallowed hard. It was hard to imagine what was really inside the canyon. It wasn't that he hadn't seen monsters before. When he was in Sang Mo village, he often followed the village's hunters into the mountains to hunt. However, this roar …

The source of the roar was right in front of him. If he continued to move forward, he would definitely encounter that monster, and at that time, there was a high chance he would be treated as food.

But if he didn't leave, Lei Ao would starve to death sooner or later. If he continued to walk, he might have a chance of survival if he avoided that monster. Lei Ao prayed in his heart, don't let it be a monster nest in front of us.

"HOWL ~ ~"

Just as Lei Ao made up his mind, the beast's roar came again. This time, it was even more intense than before. His chest felt as if it was hit by a giant boulder. "Wah!" He spat out a few mouthfuls of blood, lying limply on the ground.

It's over … Lei Ao only felt his soul drifting away, as if it could disappear at any time. His eyelids grew heavier and heavier, and that strange roar seemed to draw out all of the strength in his body.

If he were to close his eyes now, he would probably never be able to open them again. Lei Ao knew in his heart that his survival instinct had also been triggered, so he tried his best to concentrate. He definitely could not let himself fall asleep.

Just as he was entangled with that tiredness, the Phoenix tattoo on his back once again released a wave of heat. This heat quickly spread through his body, and wherever it passed, the power would gradually return. In just a moment, Lei Ao was able to stand up. The effect of the beast roar from earlier had completely vanished.

The phoenix tattoo didn't seem to be afraid of the monsters in front of him. Lei Ao's confidence instantly increased. Who knew where he got the courage to actually run forward.

He seemed to have forgotten that the phoenix was just a tattoo. Although it could transmit its power to him, it could not appear and fight for him.

Furthermore … The power of the Phoenix was not something he could control.

There were no forks in the canyon, but the further one went, the more rugged the terrain became. If it wasn't a pit half a person deep, then it would be a falling stone that was several meters tall.

The crater was created by the impact of the punch. The rocks were thrown from the mountain wall, and the monster was the one that caused all of this. Lei Ao recalled the two beast roars from before. Just this sound alone was enough to make the entire canyon tremble. The true destructive power was truly unimaginable.

Could it be that it was also trapped here? Lei Ao suddenly had a strange thought. Since they were both people who had fallen to the ends of the earth, perhaps he could befriend that weird guy.

After walking for three consecutive days, Lei Ao actually didn't feel the slightest bit of hunger. In these three days, the beast let out roars every once in a while. Until today, besides hearing the roars of beasts, Lei Ao also heard the clang clang clang, as if someone was using a hammer to smash something.

The closer he got, the more influence the beast's roar had on him. Fortunately, the phoenix tattoo in his body had always been protecting him, and every time the beast roared, a mysterious power would flow within his body, driving out that weak energy.

The passage to the canyon became narrower and narrower. When one person was barely able to pass through, a turn suddenly appeared in front of him. Lei Ao's eyes immediately lit up.

All along, he had been walking straight ahead. Now that he had encountered the bend, did it mean that the exit was right in front of him? Or was it the canyon's end?

Thinking back, it had been a while since he last heard a beast roar. In these three days, Lei Ao had a clear understanding of the beast roar's patterns. He would probably roar once every four hours. There was still about an hour before the next beast's roar, so it was unknown if the monster was still ahead.

With a perturbed heart, Lei Ao stealthily made his way around the bend, before his vision suddenly widened.

It was still bumpy mud, but the area was much larger than the canyon entrance. It was about ten acres in size, and there were walls in all three directions. There was no exit at all, only a thousand feet high bronze door at the end of the passage.

The door was very ancient. One could feel the ancient and desolate aura it exuded just by looking at it. The surface of the door was covered with copper rust.

The door was closed, and on the surface of the door was a large "Array" character. The handwriting was golden and there were traces of light flowing on the surface, as if it had not dried yet.

"That is …" Blood?! "

Lei Ao's heart shook. When he had first seen the word 'array', he had understood that the golden liquid that wrote the word 'array' was not paint, but blood, golden blood. Furthermore, the surface of the character was covered with a halo of light, as if golden blood was flowing through it.

This valley had existed for who knows how many years, and the bronze door that was covered in rust was incredibly ancient, so how was it possible that the golden blood on the words had not dried up yet?

The thousand foot high bronze door was undoubtedly the only path to this valley, but he didn't know where it led to. Besides the words "Array" and the specks of copper rust on the surface of the door, there were also obvious marks of impact as well as dozens of claw marks.

Judging from the size of the claw marks, the monster attacking this door shouldn't be small, and it was most likely the monster howling earlier. The clanging sound Lei Ao heard during these three days should have been this monster attacking the bronze door.

Monster... It was right in front of his eyes!

Lifting his gaze away from the huge bronze door, Lei Ao easily discovered that the monster was lying down on the mountain wall not far away, napping. This monster was over a hundred feet tall, and its gigantic body took up more than half of the passageway. Just the wind it breathed out was enough to cause the wind and thunder to rumble.

The giant beast's entire body was covered in black, fine, and dense scales. To Lei Ao, every single one of these scales were palm-sized. It looked like a lizard, but it had a golden horn growing in the middle of its forehead. Sharp spikes protruded from its spine, reaching all the way to its tail.

The tail was very long, but it had a broken end. The cut was very smooth, as if it had been cut by a sharp weapon. What surprised Lei Ao the most was that the beast's forelimbs were exactly the same as the human's arms. The only difference was that the beast was a hundred times stronger than the human's arms. With such forelimbs, the behemoth's attack would be more nimble.

Damn, how could there be such a monster in this world? If this fellow were to stand up, he would probably be as tall as a bronze door. Lei Ao's heart pounded a few times. Even if this giant beast fell asleep, the terrifying aura it gave off was enough to scare people to death.

Lei Ao was able to maintain his clarity of mind. It was all thanks to the phoenix in his body constantly protecting him.

Trying his best to compose himself, Lei Ao quietly moved to avoid the giant beasts and close in on the bronze door, hoping that he could open the door and escape this damned place while the giant beasts were sleeping.

However, he was disappointed. No matter how much strength he used, in front of this thousand foot high bronze door, the strength he was once proud of seemed so insignificant.

The fact that the door couldn't be opened, this was within Lei Ao's expectations. Looking at the scars on the door, it was unknown how many times the golden horned beast had attacked the door. With its abnormal form, it couldn't even open the door, which made it even more impossible for Lei Ao to do so.

They were already at the end of the canyon. Having a door meant that there was a way out, but going to the door was a sealed off path. If they were just a single step away, would they really be trapped here?
