In the dark enclosed space, a dark blue flame suddenly appeared, surging like high water, without the slightest temperature.

The next moment, a golden-red flame appeared next to it, extremely hot, with the will to burn everything.

The two flames are facing each other for tat, and they do not give in to each other.

Ye Yuan silently controlled the golden-red flames and took the initiative to attack.

The dark blue flames without wisdom were powerless against this, and they were powerless to fight back at all, and they were defeated and retreated.

After a few moments, the dark blue flames disappeared completely, leaving only golden-red flames in the enclosed space.

The next moment, the golden-red flame changed, and there was a trace of blue in its body, and then more and more, more and more, and finally the three colors were evenly divided.

"Red, Yellow and Blue!"

"Three primary colors!"

Ye Yuan's heart moved, and the three colors were superimposed on each other according to different combinations, and finally, a seven-colored rainbow appeared below the nine-story demon building, and the nine-story demon building looked even more demonic.

In fact, there are not only these seven colors, but also a touch of black and white hidden in them, but they are not visible to the naked eye.

Ye Yuan was surprised to find that these flames of different colors were not just different colors, they all had their own characteristics.

It's just that the flame is still too weak at this time, and the effect is not significant.

The phoenix bird opened its beak, and all the flames rushed into its mouth like moths to the flames, and finally disappeared.

Putting away the flames, Ye Yuan looked at the nine-story demon tower and muttered to himself in his heart.

"I didn't know what was inside, so let me see it today."

As soon as he flew into the nine-story demon tower, Ye Yuan subconsciously stopped moving forward and hovered in mid-air.

He actually sensed the danger, but the fire ladybugs in this place had already been cleared by him.

Besides, he didn't feel the presence of other creatures.

Unless it's... Dead things!

Is it a zombie?

Ye Yuan hesitated a little, unsure whether he should venture in.

The next moment, he made up his mind.

"It's all here, it's really unwilling not to go in and take a look!"

Ye Yuan first took a closer look on the first floor, there were countless dried corpses on the ground, and there were countless divine secret texts on the walls, wooden pillars, and even on the ground.

According to Professor Chen, this is the Ghost Cave script, which is no longer readable due to cultural faults.

Ye Yuan naturally can't either!

So, he didn't care about that.

After a round search, there was still nothing important to find.

The dried corpses in this place, men, women and children, high and low, are all high and low.

Unfortunately, due to the lack of literacy and literacy, it is impossible to obtain information in a short period of time.

This is true for the first floor, the same is true for the second floor, and even up to the eighth floor.

Coming to the stairs on the ninth floor calmly, Ye Yuan was faintly disappointed.

"Not a single corpse!"

"It looks like the problems are on the ninth floor!"

Ye Yuan remained vigilant and flew up slowly, but saw a scene that surprised him.

The ninth floor wasn't full of dried corpses, not even a single corpse.

The area of this floor is not large, because this demon building is pyramid-shaped, and the top floor space is small, only a dozen square meters.

There were no corpses, no strange flora and fauna, just an ordinary long stone table, just like the one in the ancestral hall.

There is a shelf on the stone table, and on the shelf is...

Ye Yuan's eyes were fixed on the things on the shelf, it was it, making him feel threatened.

It's a goose egg, covered in dust on the outside, and it's hard to see what's inside.

Gently sweep away the dust, the inside is like a stone.

I don't know why, Ye Yuan suddenly thought of the blood of the ancestral witch, isn't it in this state.

Soon, Ye Yuan shook his head and stopped his cranky thoughts.

After all, this world is too low-level, and it is impossible to have a treasure of this level as the Ancestral Witch.

"It's a pity that the Divine Sense can't be used."

The claws cautiously touched the "goose egg", and nothing abnormal occurred, and even the sense of threat that existed just now was gone.

It looks like an ordinary stone in the shape of a "goose egg", but placing a "goose egg" on the top floor of the nine-story demon building is impossible to think about with your feet.

Ye Yuan continued to search for this ninth layer, but still found nothing, there was really nothing here.

Although the origin of the "goose egg" is unknown, Ye Yuan still decided to take it with him, so he put it in his personal space.

There was no way, he had already tried it just now, cutting it with his claws, burning it with fire, or even devouring it directly, but he couldn't help it.

Although this "goose egg" is inconspicuous, it is indeed a treasure!

However, at the moment when the "goose egg" disappeared.

"Hum..."

The nine-story demon tower suddenly shook, and it shook, and the chicken moved bigger and bigger.

Ye Yuan was shocked in his heart, and quickly flew out, he didn't want to be buried alive, how dirty.

At the moment when Ye Yuan flew out of the nine-story demon tower, a black shadow flashed in the burial pit at the bottom of the building.

Ye Yuan stood outside and looked back, only to see that the originally tall nine-story demon tower was rapidly decaying, and stones, wood, and even everything turned into powder.

Even the bones of those humans and animals in the burial pit below the nine-story demon tower were the same.

"This?"

A minute later, what magnificent nine-story demon tower, what horrific burial pit no longer existed.

In the underground cavern, there is nothingness, and there is no trace of the past, leaving only a deep pit.

Suddenly.

"Haha, thank you, little bird, if it weren't for you, I wouldn't have made it!"

Ye Yuan was full of black lines.

Thinking of him, Ye is also a veteran sixth man who has experienced a hundred battles, he has always calculated others, but he didn't expect to be calculated by others today.

Ye Yuan looked at the original site of the nine-story demon building, it was now a deep pit, and there was a person in it, a young man that Ye Yuan was familiar with.

The young man was easily suspended in mid-air, he was in a good mood, and he sighed with an intoxicated face.

"It's good to have a taste of power."

Ye Yuan was full of questions now, but unfortunately, he couldn't speak.

However, I don't know if it's to confide or show off, young people are very conscious of revealing secrets.

"You must be wondering why I'm here and what this power is all about, right?"

The young man nodded when he saw the phoenix bird's cooperation, was very satisfied, and sneered.

"You always thought I was whimsical and talking nonsense, but I don't know that every word I say, even, is true!"

The young man said with a serious face, and felt the word shock from the phoenix's eyes, and an incomparable sense of satisfaction filled his heart.

For this reason, he continued to break the news.

"Actually, this nine-story demon tower is both a tomb and an altar, and the most important purpose of building it is to seal the treasures underground."

Speaking of this, he caressed the necklace around his neck with obsessive eyes and muttered.

"It's a pity that everyone doesn't know the power of this thing, let alone how to use it, it's really a tyrannical thing."

"Hehe, the ancients were ignorant, couldn't find a way to use it, and were frightened by the overflowing energy, so they sealed it."

"Speaking of which, I also have to admire their skills, they really did it."

The next moment, the young man turned his gaze to the phoenix bird and thanked him with a smile.

"However, I have to thank you for not only killing all the fire ladybugs, but also taking away the sealing core, otherwise I am afraid I will never be able to get it for the rest of my life."

Ye Yuan is now full of depression, and he has also been calculated one day.

Wrong.

Perhaps, the other party is not human!
