Ji Tianxing and Yun Yao walked through the cave and entered an empty passage.

This passage, located deep underground, is more than ten zhang high and more than three zhang wide.

The ground and the walls of the cave on both sides are paved with black boulders, which are flat and neat.

Apparently, the passage was dug by hand.

The surface of the black boulder, covered with traces of the vicissitudes of time etching, has obviously gone through a long time.

Yun Yao frowned suspiciously, and asked, "Strange, the Valley of Hundred Flowers has always been occupied by the Flower Demon and the Ten Thousand Corpse Bone Demons, how can there be an ancient passage in the depths of the earth?"

Ji Tianxing looked at the end of the passage with a solemn look, and said, "Yaoyao, the Ten Thousand Corpse Bone Demon came out of the ground of the Flower Valley before, and this passage may have something to do with it.

Moreover, I can sense that there is probably a demon cave at the end of the passage, and there is an incomparably strong demonic qi coming from ......"

Yun Yao bowed slightly: "I also sensed that there is still the breath of ten thousand corpse bone demons here, and it is very likely that it is the nest where it is hiding...... Are we going to go in again?"

Ji Tianxing thought for a moment, a cold light flashed in his eyes, and he said in a deep voice: "Damn Ten Thousand Corpse Bone Demons, they hurt us so miserably, they almost lost their lives!"

How can we let it go so easily? Let alone just run away!"

"Okay, then we have to be more cautious!" Yun Yao nodded in agreement with his decision and admonished.

Soon, half an hour passed.

The two walked along the dark boulder passage for more than ten miles underground, making several turns during the process.

Finally, the two of them are about to reach the end of the passage.

At the foot is a straight and wide boulder passage, and thousands of feet in front of it is a dark and dull hall.

Ji Tianxing and Yun Yao walked side by side, both clinging to swords, full of vigilance and vigilance.

Yun Yao suddenly frowned, and her gaze fell on the wall on the right side of the passage.

I saw that on the pitch-black stone wall three feet above the ground, there was an off-white skull.

Judging from its appearance, the skull was obviously a Terran warrior, and it was also a middle-aged man.

Ji Tianxing carefully observed for a while, and found that the bone of the skull had been strengthened, which was comparable to a god-level magic weapon.

He could basically conclude that the owner of this skull was a human warrior in the Yuan God Realm when he was alive.

At this time, Yun Yao stretched out her hand and pointed to the left wall of the passage.

I saw that on the wall on the left, three feet above the ground, there was also a skull inlaid with it.

This skull is also a Terran warrior in the Yuan God Realm.

The two skulls correspond to each other, and they are both looking down at the ground, which is quite weird.

Ji Tianxing and Yun Yao continued to move forward, and found that every ten zhang away, a pair of skulls would be inlaid on the rock walls on both sides of the passage.

The skulls are so carefully arranged that the dark passage is even more eerie, full of weirdness and horror.

"Why are there skulls embedded in the walls, is it some kind of formation or ritual?"

"Maybe it's deliberately arranged by the Ten Thousand Corpse Bone Demon to show off their status or majesty, right?"

The two walked out of the passage a thousand feet away, secretly discussing.

In the thousand-foot-long passage, there are just two hundred skulls.

Fortunately, when the two of them arrived at the end of the passage and stepped into the main hall, the skulls did not move, and there was no vision.

The main hall is very wide, with a radius of 100 feet, but it is not dark and dull.

On the ground paved with black boulders, there are twisted and dense ghost secret patterns, which seem to form a large array.

The Great Array was running, and the Secret Pattern was lit up with a dark red or purple glow, constantly flickering, light and dark.

Then the brilliance of the formation pattern, Ji Tianxing and Yun Yao could see that the walls around the main hall were carved with countless portraits of gods and ghosts.

Most of the portraits are hideous, ferocious and terrifying demons and evil gods.

In addition, in the four corners of the east, south, west and north, there are four skulls inlaid on the walls ten feet above the ground.

Those four skulls are also the heads of Terran warriors.

Although it has gone through thousands of years, it has not turned gray and white, and is still as crystal as jade.

Ji Tianxing observed carefully, and found that each skull had been tempered by thunder, leaving small thunder lines.

"These four skulls are all Terran powerhouses in the Tribulation Realm, and they have all experienced at least five Thunder Tribulations!"

This result made Ji Tianxing and Yun Yao both frown, and they felt more and more that this hall was strange and there must be some secret hidden.

Fortunately, the four skulls were inlaid on the wall without moving, and there was no abnormality.

Ji Tianxing and Yun Yao ignored it for the time being and continued to observe the situation in the main hall.

To the north of the main hall, on the ground next to the wall, there is a black altar nine feet high.

The altar was made of unknown materials, and it was inlaid with many magic crystals and blood essence stones, emitting a strange rainbow light.

The altar is also very old, at least a thousand years old.

At the top of the altar is a pool of blood with a radius of three feet.

Ji Tianxing and Yun Yao probed for a while, and saw that the sunken blood pool was filled with purple-black blood water, which was gushing.

A very pungent bloody breath came out of the pool of blood and filled the entire hall.

In the pool of blood, in addition to the tumbling blood water, there was also a large cloud of multicolored light suspended above.

Ji Tianxing looked at it and saw it clearly, in the light cluster the size of the water tank, there were hundreds of remnant souls.

Some remnants are ice blue, some are dark red blood, and some are grayish-white.

Each remnant soul represents a martial artist above the Yuan Shen Realm.

But those hundreds of remnant souls are not only human warriors, but also demon beasts, and warriors of other races.

Catalyzed by the power of the altar, the multicolored light swirls slowly.

Every quarter of an hour, a dark red stream of air would fly out of the light cluster, rising into the air.

Ji Tianxing's gaze, looking up with the air current, saw a huge blood-red skeleton inlaid on the north wall!

It was a hundred-foot-tall skeletal troll, and the bones all over its body were dark red, with a red light flowing, as if blood was flowing.

Skeleton trolls are embedded in the walls and sit on a massive throne of bones.

The white bones that sparkle like jade form a throne twenty zhang high, which is inlaid with green, blue, and red gems and crystals.

This scene is very weird, and there is a sense of horror and majesty.

Ji Tianxing and Yun Yao were both stunned for a moment, staring at the blood skeleton and looking at it carefully.

I saw that the body of the blood skeleton was also condensed from countless broken bones.

Its skeleton and body shape were almost the same as those of a Terran woman, but the proportions were more than a hundred times larger.

In the dark red skull, there are a pair of deeply sunken eye sockets, black holes inside, and there is nothing.

Its hands lay flat on the armrests of the Throne of Bones, but its wrists were chained to the throne by thick bronze chains.

Even its feet and ankles were wrapped in bronze chains, tied to the Throne of Bones.
