"Where did this thief go?"

In order not to disturb Sun Haiwei, who was in retreat, Shang Xia specially summoned the Thunderbird far away from the Yuanqi Stone Mine.

However, when he whistled one after another, he never got a response, which made Shang Xia's bad feeling become more and more intense.

After the baptism of thundercloud storm, the grade of the thunderbird should have crossed the threshold of the third order in Shang Xia's opinion.

With the speed of the Thunderbird, once it senses the danger and escapes with all its might, it is the existence of the Four Heavens, and it may not be able to threaten its safety.

"In this way, there is a high probability that the Thunderbird should not be a threat, but accidentally discovered something and quietly followed?"

Shang Xia's thoughts were churning in his heart: "I just don't know when this thief bird left, and I was careless, when the third-order earth walking corpse appeared before, the thunderbird neither warned in advance nor helped, I should have thought of it." Otherwise, with the help of Thunderbird, this battle would not have been so difficult, and Sun Haiwei would not have been seriously injured and forcibly retreated in this wild place. ”

Shang Xia pondered what the Thunderbird might find, and at the same time he was more and more careful to hide his figure, and at the same time increased the scope of patrol.

Without the Thunderbird to provide vigilance in the sky, Shang Xia could only confirm the safety of the surrounding area as much as possible.

With the Yuanqi Stone Mine as the center for most of the circle, everything was normal, and it seemed that after the beast tide, the entire battle domain of the two realms had become a lot calmer.

This made Shang Xia's heart feel a lot more relaxed, and when he looked around casually, he suddenly saw a coral forest that was only a few miles away from here.

Shang Xia was slightly stunned in his heart, the ptarmigan wouldn't have flown into the coral forest, right?

According to Sun Haiwei, the coral forest itself is a large labyrinth formed by natural formations.

If the Thunderbird strayed into it, it would naturally not be able to hear Shang Xia's call.

But the question is, whether the Thunderbird entered by mistake or other reasons, Shang Xia still doesn't know.

Also, it is said that the coral forest is forbidden to the sky, and even if the master of the four heavens enters, he has to leave his body and walk on foot.

In that case, the Ptarmigan shouldn't have been near the coral forest at all.

Unless, the so-called "forbidden space" is only forbidden by virtue of its own cultivation as an existence that flies, not a bird that is born to fly.

In addition to the strangeness of the sudden disappearance of the Thunderbird, what made Shang Xia wonder in his heart was how the third-order earth walking corpse appeared.

Although the Coral Forest was close at hand, how could a third-order earth walking corpse coincidentally appear here?

And for a long time before that, there was no sign of a living corpse in the coral forest.

This news was only heard shortly after he entered the Two Realms Battle Domain, and it was because of this news that Liu Jitang may have secretly drained most of the guardian power of Tongyou Peak and entered the Coral Forest.

Shang Xia looked back at the coral forest a few miles away again, the third-order earth walking corpse was undoubtedly a member of the Zhu family before his death, and something must have happened in the coral forest now.

It's a pity that I can't go in and find out.

Sun Haiwei is temporarily in retreat here to recover from her injuries, and he can only stay here for the time being, waiting for her to come out.

Shang Xia went around the Yuanqi ore pit in a big circle, but came back with a lot of thoughts.

But the moment he walked to the edge of the mine, the man suddenly stopped in place, and looked at the pit with some solemn eyes.

There was originally a waterhole below, and Shang Xia and Sun Haiwei also fell into the waterhole one after another.

But now, the water in the pool is gone, revealing the bottom of the pit with a puddle of silt below!

Where did the pool go?

Shang Xia first glanced around vigilantly, and after seeing that he didn't find anything, he hurriedly went to the grotto where Sun Haiwei was retreating, and found that the portal he blocked there did not show any signs of being moved.

Shang Xia quietly stayed outside the grotto for a moment, and could vaguely sense the signs of the slow flow of vitality into the grotto, and couldn't help but breathe a sigh of relief.

At that time, after the two of them came to the Yuanqi Stone Mine, they were suddenly attacked by the third-order earth walking corpses, and they didn't have time to think about many things.

Looking back now, I feel that there are doubts everywhere.

This Yuanqi Stone Mine is used to mine Yuanqi Stone, how can there be water at the bottom of the pit?

Even if it was rain, it wouldn't have accumulated into such a big pool.

Even if it is because of the change of topography, the bottom of the Yuanqishi pit is connected to the underground water vein, but what is the reason for the disappearance of this pool of water?

Could this water still flow back?

Shang Xia came to the bottom of the pit with doubts, ignoring the silt below and probing little by little.

He soon made his way to the center of the bottom of the pit, where the academy had left a coordinate ban.

It was because the coordinate prohibition here was damaged and invalidated that the academy lost the specific location of this pit after the beast tide.

Originally, I thought it was caused by the destruction of the beast tide after it crossed, but now it seems that this may not be the case.

Shang Xia brushed away the mud under his feet, revealing the cracked stone slab below, which was carved with many forbidden patterns, and the many Yuan Qi stones inlaid on it had failed.

Shang Xia followed the largest crack and traced the siltation all the way, and soon found a hole enough for one person to enter and exit under a thin layer of siltation.

Quirky might be here!

Shang Xia sighed secretly, although the walls around this cave had been eroded by the current, Shang Xia could still see that the cave was not a natural formation, but had just been opened up, and the pioneer was none other than the third-order earth walking corpse!

So, where does this hole lead?

A hint of hesitation flashed on Shang Xia's face, and he glanced back at the grotto where Sun Haiwei was retreating, and then jumped down from the cave.

The third-order earth walking corpse was truly extraordinary, not only being able to open up passages underground, but also being able to tamp and widen the dirt on the surrounding walls, making the cave look more like a deep well.

Shang Xia had already bottomed out after only three zhang down the hole in the ground, but what appeared in front of him was an underground passage that was obviously dug out by hand!

It's just that this passage doesn't seem to be finished, and it just so happens to open up here, and behind Shang Xia is a hard earth and stone wall.

Shang Xia originally thought that it would be an underground dark river, but he squatted down and touched the remaining flowing water on the ground, and then looked at the walls opened up on both sides, as well as the arched passage, and knew in his heart that the earth walking corpses did not have such skills!

This is obviously an underground passage that has been artificially carved out for an unknown number of years.

The third-order earth walking corpse may have walked to the end along this passage, and after finding that this path was impassable, he directly opened a hole in the ground above his head.

Shang Xia didn't say a word, pulled out the Jade River Sword at his waist, and walked along this passage towards the front.

However, Shang Xia obviously underestimated the distance of this passage, and walked out of this breath for fear that there would be no three or five miles, but he still never came to the end.

The underground passage is difficult to discern the direction, and this passage is not straight, Shang Xia didn't know his current approximate location for a while, but he intuitively felt that he was afraid that he was going towards the coral forest now.

It's just that Shang Xia is strange in his heart, could it be that this coral forest can still enter and exit from the ground?

If it were that simple, he didn't believe that anyone else would have thought of it.

There must be something weird!

Shang Xia muttered in his heart, but suddenly noticed that there was a faint light flickering on the wall in front of him.

Shang Xia was vigilant in his heart, and slowly approached the past, but saw a colorful light curtain flickering at the end of the passage.
