From the top of the cave to the bottom, it is about several dozen feet high, and there is no place to climb or stand.

If a mortal fell from here, he would surely die, but the dragons can all fly in the clouds, so there is no problem and they can land steadily.

After Long Long entered the secret realm, he scanned the distance again to confirm the location of Lu Yan and Lu Ya.

For the enemy, use scanning; for companions, use hints. Long Long is confident that this underground exploration is foolproof and there is no chance of any mistakes or accidents.

Impossible! Absolutely impossible!

The crowd walked towards the depths of the cave, passing through many long corridors, only to see that the cave ceiling in front was getting lower and lower, and the aisles on both sides were getting narrower and narrower.

Qin Zhou and Qin Ye walked very carefully, fearing that they would be suddenly turned back by Lu Yan, Lu Ya and others at a corner and bump into them.

However, Long Long used A Jing's much larger scanning range of spiritual sense to keep a distance from the two white tigers in front of him at all times, so he looked calm and unhurried.

In the eyes of the Qin brothers and sisters, this naturally became a proof that Long Long was fully confident and had everything under control, and their original nervousness and anxiety also subsided a lot.

As for the dragon fox, it was wandering around and looking left and right. It didn't look like it was exploring a cave. Instead, it was like a puppy patrolling its own territory, and it looked very curious and excited.

Finally, we arrived at the end of the corridor, which was another huge cave. There were a large number of corridors built along the walls of the cave, winding and rotating like a giant snake.

And in the center of the cave, there really was a giant snake coiled up. Its body was as huge as a mountain, and its scales were pitch black and dull, as if it could swallow the light of the sun and the moon.

Just by looking at the giant snake, the four of them felt a shudder rising from deep in their blood.

"Snake slough." Long Long suddenly said, "This is not a living creature, it is just the slough of an ancient scale-bearing creature."

Everyone quickly used their spiritual sense to scan the area and found that it was just as Long Long had said, the inside of the giant snake was hollow, without any flesh and blood at all.

"Could this be the Earth Root Python?" Qin Zhou said hesitantly, "I heard that in the era when the Dragon Clan ruled the Eastern Emperor Realm, there was a clan of giant pythons living in Zhongzhou. They were later subdued by the Dragon Clan Emperor and helped him to open up mountains and build civil engineering projects."

After he said that, Long Long finally remembered.

The position of the Ground Root Python among the Scaled Clan is like that of the Golden Winged Peng Bird among the Feathered Clan. Due to its sturdy body and infinite power, it can play a unique role in many places.

Unfortunately, the Dragon Emperor later fell into the mortal world, and the political situation in the Eastern Emperor Realm also changed dramatically.

Although there is no conclusive evidence, it is generally believed that the Earth Root Python clan was attacked by their old enemy during that period, and eventually their bloodline was completely cut off.

"It is said that this ground python has another nickname, called 'earth dragon', which can easily cause earthquakes." Qin Ye suddenly thought of something, his eyes lit up, "Its scales belong to the earth of the five elements, and holding them can perform the earth escape method."

"If we can bring the scales back, won't we be able to gain the trust of the ancestor?"

Long Long scanned silently for a moment and found that the two people were walking in the corridor of the cave wall in the distance.

If he followed them to the corridor along the cave wall, the chance of being discovered would inevitably increase. It would be better to hide in the snake skin below, use the power of Ajing to block the spiritual scan, and then search again after the two men left.

"Okay." He nodded in agreement.

In order not to cause fluctuations in the spell, the four people did not fly directly into the clouds, but climbed down with their bodies.

Long Long held the little fox in his arms and jumped flexibly on the protrusions of the rock wall.

He was already proficient in the Fenyun Bagua Step. Although he had not used this step at this time, he was able to rely on his experience to fly over the eaves and walls, and move skillfully without making any sound. He rushed down the rock wall and left Qin Zhou and Qin Ye behind.

The dragon fox hugged his neck tightly with its tail wrapped around his waist. It was so thrilling that it wanted to scream, but was afraid of being heard by the enemy, so it could only cover its mouth with a blushing face.

The four of them finally reached the bottom of the cave. From this angle, the snake slough of the ground python looked even bigger, and just looking at it was terrifying.

"Huh?" Dragon Fox suddenly said in surprise, "Look, does this coiled snake skin look like a building?"

Upon hearing this, everyone looked carefully and saw that at the tail of the snake skin, there was indeed the outline of a man-made entrance hall, leading to the pitch-dark interior of the snake skin.

Apparently someone used the empty shell shed by the ground python and built it into some kind of building.

Long Long scanned again for a moment, then led everyone into the snake shell.

As soon as I entered, I felt a damp and fishy smell coming towards me.

The other three were from the scaly tribe and were not afraid of the fishy smell. Only the little fox had a sensitive nose and was almost choked to tears. He had to hold his breath.

There were countless corpses hanging from the ceiling. They were all remains of various feathered creatures. They were tightly tied up with translucent silk threads, with their heads hanging upside down.

Everyone recognized the translucent silk thread; it was some kind of sealing device made from dragon saliva, specifically used to restrain captives.

On the side against the wall, various torture instruments were placed, and a large number of jade slips were piled on the table.

Long Long picked up a jade slip, looked at it for a moment, and knew that this trip was right.

If this place were to be exposed by the White Tiger Clan, I'm afraid the relationship between the Scale Clan and the Feather Clan would be destroyed.

The jade slip records some very strange experiments:

Blood fusion experiment.

The experimenters started from the mechanism of the giant Kun transforming into the Peng, and believed that since the scaly clan can transform into the feathered clan, it proves that the blood isolation between different demon clans is not an insurmountable barrier.

Therefore, they collected blood samples from various feather tribes extensively and conducted exploratory research.

So far, 112 types of Feather Clan bloodlines have been studied, and only three of them have the potential to merge with the Scale Clan bloodlines.

The fusion here does not mean that individuals of two bloodlines intermarry and give birth to offspring. Rather, it means that the two bloodlines exist in an individual at the same time, and they cannot devour each other, nor will they conflict with each other, allowing the individual to simultaneously exert the magical powers of the two bloodlines...

Thinking of this, Long Long couldn't help but look at Long Hu.

He also roughly guessed why Emperor Yinglong was conducting this experiment here:

I guess he had already anticipated that there would be some irreconcilable blood conflict between his wife and his daughter, Longhu.

Perhaps the "secret method of blood fusion" mastered by the Jiaolong clan in Beiming Fanyang is the final product of the experimental project here?

Thinking of this, Long Long hurriedly flipped through more jade slips.

It is a great pity that most of the remaining jade slips are just some data and conjectures, without any substantial conclusions, nor any ready-made scriptures on martial arts.

After putting these jade slips into the storage bag, Long Long scanned the area again.

Lu Yan and Lu Ya were still walking in the corridors of the cave wall. They did not stay in any room for too long. It seemed that they did not find anything valuable.

Thinking of this, Long Long quickly made a decision:

"We have found evidence that can convince the tribe. Let's leave now!"
