Chapter 120

"Where did this thief bird go?"

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

However, after he sent out whistles one after another, he never got a response, which made Shang Xia's uneasy feeling even more intense.

After being baptized by the thunderstorm, Thunderbird's grade should have crossed the threshold of the third grade in Shang Xia's opinion.

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

"In this way, Thunderbird should most likely not encounter a threat, but discover something by accident and follow up quietly?"

Shang Xia's thoughts were churning: "I just don't know when this thief bird left. I was careless. When the corpse of the third-order land appeared before, Thunderbird neither warned in advance nor helped, so I should have I thought of it. Otherwise, with Thunderbird's help, this battle would not be so difficult, and Sun Haiwei would not be seriously injured and forced to retreat in this wild place."

While thinking about what Thunderbird might find, Shang Xia became more and more careful to hide his figure, and at the same time increased the scope of his patrol.

Without the Thunderbird providing warning in the sky, Shang Xia could only confirm the safety of the surrounding area as much as possible.

Around half a circle around the Yuanqi Stone Mine, everything is normal. It seems that after the beast tide, the entire battlefield of the two worlds has become much calmer.

This made Shang Xia feel a lot more relaxed. When he looked around casually, he suddenly saw the coral forest that was only a few miles away.

Shang Xia was slightly taken aback, the thunderbird flew into the coral forest, right?

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

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

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

Also, it is said that the coral forest is forbidden to go empty, even if a master of the fourth heaven enters, he will have to walk down and walk on foot.

It's just that according to this, Thunderbird shouldn't be near the coral forest at all.

Unless, the so-called "forbidden air" only prohibits the existence of flying away by virtue of its own cultivation, not the birds that are born to fly.

Aside from the strangeness of Thunderbird's sudden disappearance, what made Shang Xia suspicious was how the third-tier walking corpse appeared.

Although the Coral Forest is very close at hand, how could it be that a third-tier earth walking corpse just happened to appear here?

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

This news was only heard shortly after he entered the Two Worlds Battlefield, and it was because of this news that Liu Jitang might have secretly evacuated most of Tongyou Peak's guarding power and entered the Coral Forest.

Shang Xia looked back at the coral forest a few miles away again. The third-order corpse must have belonged to the Zhu family, and something must have happened in the coral forest.

It's a pity that I couldn't get in to find out.

Sun Haiwei retreated here temporarily to recover from her injuries, and he could only stay here temporarily, waiting for her to leave the retreat.

Shang Xia circled the Yuanqi Ore Pit for a long time, but came back full of worries.

But the moment he walked away from the edge of the mine, he suddenly stopped in place, looking towards the edge of the mine with some serious eyes.

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

But now, the water in the puddle is gone, revealing the bottom of the pit below which is a puddle of mud!

Where did the water go?

Shang Xia first looked around vigilantly, and after finding nothing, he hurriedly went to the grotto where Sun Haiwei was retreating, and found that the door blocked by him did not show any signs of being moved.

Shang Xia stayed quietly outside the grotto for a while, and could vaguely feel the signs of vitality slowly flowing into the grotto, so he couldn't help but breathe a sigh of relief.

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

Looking back now, I feel suspicious everywhere.

This vitality stone mine is used to mine vitality stones. How can there be water at the bottom of the pit?

Even if it was because of the rain, it would not have accumulated such a large pool.

Even if the groundwater veins were connected to the bottom of the Yuanqi Stone pit due to changes in the terrain, why did the pool of water disappear?

Could this water still flow back?

Shang Xia came to the bottom of the mine with doubts, and explored bit by bit regardless of the mud below.

He soon came to the center of the bottom of the pit, where the academy left the coordinate restriction.

It was because the coordinate restriction here was damaged and invalidated that the college lost the specific location of this mine after the beast tide.

Originally thought it was caused by the destruction of the animal horde, but now it seems that may not be the case.

Shang Xia brushed away the mud under his feet, revealing the cracked stone slab below. There were many forbidden lines engraved on the slate, and the vitality stones inlaid on it had all expired.

Shang Xia followed the largest crack, opened up the silt all the way to investigate, and soon found a cave under a thin layer of silt that was big enough for one person to enter and exit.

The weirdness might just be here!

Shang Xia sighed secretly. Although the walls around the cave were eroded by the water flow, Shang Xia could still tell that the cave was not formed naturally, but was just dug out, and the person who opened it up was none other than the other side. Undoubtedly a third-order ground walking corpse!

So, where does this burrow lead to?

A trace of hesitation flashed across Shang Xia's face, he turned his head and glanced at the grotto where Sun Haiwei was retreating, and then jumped down from the cave.

The third-order ground walking corpse is really extraordinary. Not only can it open a passage underground, but it can also tamp and widen the soil on the surrounding walls, making the cave look more like a deep well.

Shang Xia walked down the cave for only three feet before bottoming out, but what appeared before him was an underground passage that was obviously dug by hand!

It's just that this passage seems to be unfinished, and it just happened to be opened here. Behind Shang Xia is a hard wall of earth and stone.

Shang Xia originally thought it would be an underground river, so he knelt down and touched the remaining running water on the ground, then looked at the walls opened on both sides and the arched passage, and he knew in his heart that the walking corpse on the ground is not like this. Wait for the craftsmanship!

This is obviously an underground passage that was opened up artificially, and I don't know how many years it has existed.

The walking corpse of the third level may have walked to the end along this passage, and when it found that the road was blocked, it directly opened a hole above its head and went out.

Without saying a word, Shang Xia drew out the Yuhe Sword from his waist, and walked forward along this passage.

However, Shang Xia obviously underestimated the distance of this passage. It may not be three or five miles away, but he still hasn't come to the end.

It is difficult to tell the direction of the underground passage, and this passage is not straight. Shang Xia didn't know his current position for a while, but he had an intuition in his heart that he was probably going towards the coral forest.

It's just that Shang Xia felt strange in his heart, could it be possible that this coral forest can still come in and out from the ground?

If it was really that simple, he didn't believe that other people would not have thought of it.

There must be something weird!

Shang Xia murmured in his heart, but suddenly found a faint brilliance flickering on the wall in front of him.

Shang Xia was vigilant and approached slowly, only to see a colorful light curtain flickering at the end of the passage.
