Bi Xuan looked at Luo Yan and said disappreciatively: "What's so funny, the military camp is no better than the outside, I follow you like this, so as not to attract too much attention." ”

Luo Yan nodded in approval, and then the two followed the King of the Eternal Night towards Jinghai City.

Half a month later, the army came to a fortified city, and heard the sound of fighting in the distance.

The King of the Eternal Night climbed the city wall and looked forward, only to see a sea beast under black pressure, launching an attack.

These sea beasts, regardless of their cultivation to the high bottom, seemed to be not afraid of life and death, and they rushed forward wave after wave, almost stepping on the corpses of the previous wave to move forward.

Luo Yan felt that this situation was a bit unreasonable, and he made a bold assumption in his mind: Could it be that something was wrong with the place where the sea beast lived?

Back in Jinghai City, Luo Yan told the King of the Eternal Night about his guess.

The King of the Eternal Night thought back to what he had seen, and felt that Luo Yan's inference was also reasonable.

After the two discussed, Luo Yan came up with a bolder idea:

The King of the Eternal Night continued to organize personnel to resist the attack of the sea beast, and Luo Yan went to the hinterland where the sea beast lived alone to check the details, since he was not an undersea giant, so this trip should not arouse suspicion.

Bi Xuan was worried about Luo Yan's safety and didn't want to stay and wait, so she decided to go to the hinterland of sea beasts with him disguised as a double cultivator.

After some preparation, the two of them left Jinghai City, bypassed the place of battle, and flew to the area where the sea beasts lived.

On the way, the two saw groups of sea beasts running from the hinterland in some panic, and after gathering thousands of miles away from the border, they began to run towards the residence of the underwater giant clan.

The two of them flew forward non-stop for more than a month, and then saw an undersea mountain range, tens of thousands of meters high, with no edge in sight.

Luo Yan noticed that many sea beasts were running out from here, fleeing in three directions, and the demon beasts heading to the direction of the undersea giant clan were only some of them.

He looked at Bi Xuan for a moment, flew into the mountain range, came to a high ground and observed for a moment, and then began to walk towards the interior of the mountain range.

After seeing the two of them, the sea beast they encountered looked at each other and left in a hurry, as if they had no intention of being their enemy.

The two of them walked forward for more than ten days, and gradually began to hear a strange sound, which became louder and louder as they went deeper.

The two of them raised their vigilance, and Luo Yan released his divine sense to check the places within a radius of thousands of miles, and found that there was nothing suspicious except for the fleeing sea beasts.

So he continued to walk cautiously.

Bi Xuan grabbed Luo Yan's hand a little nervously, and the two walked forward for seven days one after the other, and this strange sound came out again.

This time they heard it very clearly, like the beat of a drum, and after three thuds, knocks, knocks, and then disappeared, and then fell silent for seven days before the sound sounded again.

The careful Luo Yan found a pattern, this sound would ring three times every seven days, and then fell silent.

As the two of them continued to move forward, they were now approaching the center of the mountain range.

At this time, there were many corpses of sea beasts below the primordial infancy on the ground, their eyes, ears, nose, and mouth all had traces of blood, and some of the bodies of the lower-level sea beasts had exploded, and the death was terrible.

Luo Yan looked at the demon beasts running by him, they all showed horror, and they didn't even want to delay when they glanced at them.

There were several Avatar Stage Sea Beasts following behind a group of Sea Beasts below the Yuan Infant Stage, escorting them to evacuate.

Just as Luo Yan was looking at the sea beast, the sound like a drumbeat came out again:

Knock –

Luo Yan only felt a shock in his heart, and there was a feeling of upward surging qi and blood in his body, while Bi Xuan directly mobilized his true qi to calm the discomfort in his body.

Knock –

Then another sound came, and the bodies of some low-level sea beasts were shocked and burst open, and their corpses fell on the way to escape.

Knock –

After the third sound, another wave of sea beasts bleeds, their bodies fell to the ground, and the undead sea beasts desperately fled from here.

Luo Yan guarded the Divine Sea and let go of his Divine Sense again, but still found nothing.

However, judging from the sound he had just heard, the object that made such a terrible sound should still be in front of him.

After the two of them found their way, they became more cautious, and they flew forward quickly during the seven-day gap.

At noon on the seventh day, Luo Yan asked Bixuan to release the body protection light film, ready to deal with the strange noise.

And he himself also used his true qi to guard the soul lake and the sea.

Just after Bi Xuan had just done a good job of protection, the sound of knock, knock, knock came again, and this time the sound had a greater impact on their qi and blood than last time, and Luo Yan only felt that his spirit also beat.

The sea beasts in this place have become scarce, and occasionally there will be a god transformation stage, but they are all in a hurry to fly out.

After three sounds, Bi Xuan put away the body protection light film, and the two continued to fly forward.

For another seven days, the two of them came to a high mountain peak, ready for the next strange noise.

There was no trace of the sea beast here, Luo Yan judged that the destructive power of the sound here should be stronger, so he let Bi Xuan get close to him, and he released a protective light film to cover the two of them inside.

Bi Xuan leaned on his shoulder, and also urged the true qi in his body, protecting his body, and the body protection light film of the two perfectly coincided.

Soon after they were ready, the strange sound came as scheduled, Luo Yan felt that the protective light film trembled under the impact of this sound wave, and Bi Xuan felt the blood churning in her body, faintly unable to suppress it.

Seeing this, Luo Yan poured a breath of true qi into her body and helped her suppress the abnormal movement in her body.

After three sounds, Bi Xuan's face became a little pale, thinking that if it wasn't for Luo Yan's help just now, it is estimated that she would have exploded and died like a sea beast.

She looked up at Luo Yan affectionately, her body still leaning on her broad shoulders, enjoying the feeling of being protected.

Seeing that the danger had passed, Luo Yan patted his arm and said:

"The damage of the strange sound here is already very strong, moving forward, I'm afraid it will be difficult for you to resist next time, why don't you lie back in the crystal coffin first, and then come out when you are safe in the future?"

Bi Xuan shook her head and said a little coquettishly: "Isn't there still seven days? I'll accompany you for another seven days, and when the strange sound is coming, I'll go into the crystal coffin, and as soon as the sound passes, you're letting me out, okay?"

Luo Yan nodded in agreement, and then they flew forward again.

Seven days later, Luo Yan put her into the crystal coffin in time, and then released the protective light film, urging the true qi and strengthening the defense of the light film by a few points.

This time, the sound of knock-knock-knock sounded right next to him, and every blow made his body tremble, and the light film on his body was also trembling violently, and the sound wave shook his qi and blood, and the soul lake was turbulent.

After three sounds, everything became quiet again, Luo Yan once again released his divine sense to look within a radius of thousands of miles, and strangely enough, he still didn't find anything abnormal, he condensed his divine sense together, combined with Tianqing Huimu, and looked in a direction in front of him.

Then, he finally saw a hint of it, and in the distant mountain, he found a huge vague outline, lying there horizontally, and there was a red area within the outline, which was particularly dazzling.

In order to see more clearly, he flew forward for a while, and stopped more than 10,000 miles away from the outline, and when he used Tianqing Huimu to check again, he found that the outline turned out to be a strange demon beast shape.

The head is like a dragon's head, with a single horn, a body like a lion, a nose like a dog, a foot like a unicorn, like a dragon but not a dragon, like a tiger but not a tiger, like a lion but not a lion, like a unicorn and not a unicorn, like a dog and not a dog, and that red area is just in the heart of this monster.

Luo Yan checked the surrounding environment again, and judged that this should have reached the center of the mountain range.

Looking around, there is not even a single living creature to be seen here, and all that remains on the ground is piles of white bones, and it seems that the sea beast here has been dead for a long time.

Standing here, even if it was not yet time for the strange sound to come out, I also felt that the qi and blood in my body were a little restless, as if I was attracted by something, and there was a feeling that it was about to gush out.

Luo Yan summoned his true qi to resist, calculating the time, there were still five days before the next beat, he decided not to move forward rashly, it was better to stay here and observe for a while.

He found a large bluestone, placed several circles on it to defend against sound waves, and sat down on the stone.

With the protection of the formation, he felt that the abnormality on his body had been basically eliminated, so he divided a wisp of divine thought to tell Bi Xuan in the crystal coffin about the situation outside.

After hearing this, this woman hoped to come out and take a look, so Luo Yan had no choice but to release her again.

As a result, as soon as she came out, she felt the flesh on her body begin to swell, and she felt like it was about to explode.
