In the dim cave, Lin Qiye moved forward rapidly.

It was unknown whether the queen ant had entered a state of last-growth or had initially recovered from her injuries, but she was crawling faster and faster, and in Lin Qiye's spiritual perception, the distance between them was gradually increasing...

In the end, the queen ant escaped Lin Qiye's perception.

However, Lin Qiye did not stop there. First, there was only one passage in the cave, so there was no possibility of being thrown away. Second, there was blood of the queen ant on the ground. As long as he followed the blood trail, he would always find her.

Lin Qiye chased in the dark cave for about a few minutes, and then the narrow rock walls on both sides suddenly disappeared, and the surrounding space suddenly became clear.

Lin Qiye was stunned and gradually slowed down.

This is a dark and empty underground space. Even if Lin Qiye extends his spiritual perception to the limit, he cannot detect its edge. In other words, the diameter of this space is at least over 500 meters.

Lin Qiye looked back and saw a circular cave several meters high embedded in the flat and smooth wall behind him. He had just walked out from here.

He frowned slightly, walked to the wall, and gently rubbed the surface of the wall with his hand.

Unlike the rock walls inside the cave, this vast flat wall is built with blue-grey bricks. It feels cool when it touches the skin. There are no gaps between the bricks, as if they were grown together. The workmanship is extremely delicate.

There were some broken bricks and soil scattered on the ground in front of the wall, which were probably caused by worker ants destroying the wall when they were digging holes.

"Man-made?" Lin Qiye looked at the magnificent blue-gray wall in front of him with shock in his eyes.

You know, this is not some other place, but the deepest part of the primeval forest, an underground space nearly 100 meters from the ground. How could there be such a magnificent man-made wall here?

And judging from the quality and workmanship of the bricks, this doesn't seem to be a modern architectural style...

Lin Qiye withdrew his hand, thought for a moment, and continued to walk forward along the bloodstains on the ground.

Although the origin of this wall is indeed suspicious, the top priority at the moment is to hunt down the seriously injured queen ant. However, Lin Qiye did not relax his vigilance. In such a strange environment, he has exerted his perception ability to the extreme and is ready to deal with possible dangers at any time.

On the ground, the queen ant's bloodstains were getting less and less, and the clues were becoming more and more vague. It seemed that the queen ant was not having a last gasp, but was recovering from her injuries quickly.

After all, it is a mystery of the "sea" realm. Even if half of its body was blown off, it would not die so easily.

Lin Qiye followed the blood trail forward, and suddenly he seemed to sense something, and he froze in place.

He looked up at the deep darkness ahead, a look of deep horror in his eyes.

"Wildfires cannot be extinguished; spring breezes will bring new life."

puff--!

A faint flame bloomed in Lin Qiye's palm. With this light, Lin Qiye finally saw the scene in front of him clearly.

In front of him, another wall appeared, but unlike the previous one, this wall was completely black and emitted a strange black light, absorbing all the light that fell on its surface.

In the center of the wall, a magnificent and ancient bronze gate stood on the ground, about thirty meters high. The dusty surface of the gate was covered with mottled dark green copper rust, and it appeared dark red under the firelight. If you stare at it for a long time, the strange dark red would be imprinted in your mind and could not be erased.

Lin Qiye immediately shifted his gaze and looked up at the top of the door. The firelight in his palm could not illuminate the entire picture of the huge bronze door, but even so, standing under this huge bronze door, he could feel an inexplicable sense of oppression enveloping his heart.

The most crucial problem is that Lin Qiye's spiritual perception cannot penetrate this bronze door. Not only this door, but also the black stone brick walls on both sides of it are impenetrable. It seems that there is an invisible force that is repelling Lin Qiye's spiritual power and prohibiting any existence from entering.

"What on earth is this..." Lin Qiye's brows were furrowed, and the doubt in his eyes became even stronger.

This is the northernmost border of Daxia, deep in the primeval forest, beneath the earth...Except for Lin Qiye and his companions, it is impossible for anyone to have arrived here, but here, such a strange and mysterious man-made building appeared.

When did it appear? Who created it? What is its purpose?

A series of doubts surged into Lin Qiye's mind. He stood in front of the huge bronze door and fell into deep thought...

Suddenly, as if he thought of something, he began to search around the huge bronze gate.

Judging from the dust on the door, this door has not been opened for a long time. If this is the case, it means that the queen ant did not pass through this door, so where did she go?

After a moment, Lin Qiye found the answer.

I saw a huge hole digging into the ground at a corner of the wall about fifty meters away from the bronze gate. It was about seven or eight meters wide, just the size of the queen ant. Judging from the angle of the hole, the queen ant must have dug a hole from the ground, passed the black wall, and went directly behind the wall...

No, that's not right!

Lin Qiye carefully observed the broken soil on the ground, his brows furrowed tighter and tighter...

The soil at the edge of the cave is not curled inwards, but cracked outwards, and judging from the touch of the soil, it must have been dug up for a long time.

In other words... this hole was dug from the inside of the wall to the outside, and it existed a long time ago!

Lin Qiye slowly stood up and looked towards the cave entrance with a serious look.

He originally thought that the queen ant was just a mystery that only descended into the cracks in the ground, and this passage leading to the inside of the giant bronze gate should have been left by her for escape, but now it seems that this is not the case.

The queen ant is the creature that escaped from behind the giant bronze gate!

Lin Qiye looked at the trace of blood remaining at the entrance of the cave and sighed helplessly.

Everything before him had exceeded his expectations. Whether it was the door itself or the unknown risks behind it, they seemed to be warning him not to go any deeper...

He really wanted to kill the queen ant, but after analyzing the current situation rationally, he knew it was no longer appropriate to continue chasing her.

This mission is destined to end here.

Lin Qiye turned his head and prepared to leave here for the time being, but at this moment, his body froze again.

The faint light of the fire danced in the dark underground space. Under the dim light, pale paper figures had surrounded him without anyone noticing...

Their empty eyes stared straight at Lin Qiye, and the corners of their mouths painted with a scarlet brush curled up in a strange arc, as if they were smiling.
