The creatures in the pictures that Yun Rui showed him just now, the gods and demons, and the essence blood all have their memories, so Zhao Lei is very clear about their situation!

These four creatures are all particularly famous species in the demon race, especially the last demon beast, whose status in the demon race is simply equivalent to the emperor of human feudal society!

Any of these four creatures has reached maturity, and it is not an existence that can be matched by humans on Earth.

Take the wolf-like creature in the first picture as an example, its real name in the demon clan is the thundercloud wolf, it is the most powerful race of thunder demon beasts in the entire demon clan, they are the darlings of heaven and earth, and they are born close to thunder and lightning!

After cultivating to maturity, the power of thunder and lightning in their bodies will undergo a fundamental transformation, and they will become powerful demon beasts in the Demon King Realm.

The powerhouses of the Five Elements Realm of the human race can only be regarded as the same level as the demon beasts of the Demon Pill Realm in the Demon Clan.

Above the Demon Pill Realm, there is also the Demon Infant Realm, and the realm above the Demon Infant Realm is the Demon King Realm!

Even if it is the biggest backer behind the Meng family, a powerful existence above the Transformation Realm, it is vulnerable in front of the Demon King Realm, no different from ants.

The rhinoceros-like demon beast in the second picture is also a powerful group in the demon clan, and it is called the Wangtian rhinoceros in the demon clan!

The sky-looking rhinoceros is naturally compatible with the starry sky, has an excellent perception of the power of space, and has grown to maturity, and is also a demon beast at the level of the Demon King Realm, and they are even more difficult to deal with than the Thundercloud Sky Wolf!

There has always been a classic saying among cultivators, that is, space is king, and time is respected!

As long as you master these two artistic conceptions, even if you face a higher cultivation than them, you can easily get out.

Although the attack power of the Sky Gazing Rhino is not as strong as that of the Thundercloud Heavenly Dragon, its spatial power is not at all something that humans can compete with!

The ape creature in the third picture is a powerful branch of the demon ape clan, the fire spirit ape, which is born with a close fire attribute, even in the demon world, they generally live in volcanoes and swim in magma!

These three demon beasts, each of which is a powerful race among the demon clan, are not at all comparable to the demon clan that is now confronting humans.

According to the memory of the armor-piercing beast, the demon clan that is attacking humans now can only be regarded as a small demon country in the demon clan!

Compared with the peak races of the demon race, such as the Thundercloud Sky Wolf, the Sky Gaze Rhino, and the Fire Spirit Ape, they are not stingy with the difference between the Firefly Light and the Haoyue.

But what made Zhao Lei most excited was the creature he saw at the end, which looked like a puppy, very inconspicuous.

Zhao Lei recognized this kind of demon beast, it was the Netherworld Qilin, one of the ten emperor clans of the demon clan!

The Netherworld Qilin, a symbiosis of darkness and light, is also one of the top three existences among the ten emperor clans.

These four creatures, each of which has noble blood, just makes him wonder where Yun Rui got the news of them and can still leave video data.

Time passed slowly in Zhao Lei's confusion, and about twenty minutes or so, there was finally a sound from the door of the monitoring room, and then Yun Rui stepped in

"Hehe! I've kept you waiting," Yun Rui smiled and sat down beside Zhao Lei, with a hint of relief on his face.

"I've discussed your conditions with the above, and I can promise to tell you about them, but you must promise not to leak them, and tell us everything you know!" Yunrui said.

"No problem!" Zhao Lei nodded.

Yun Rui sat on the chair, picked up the teacup and took a sip of water, and then said slowly: "The creatures in the four pictures I showed you are on the earth, to be precise, at our feet!"

"What!" Zhao Lei got up violently and looked at Yun Rui in shock, his eyes full of incredulity.

"Right at our feet?" Even though he had thousands of guesses in his heart just now, he didn't expect those powerful demon beasts to be at his feet.

"Back then, our Huaxia Kingdom discovered a mysterious cave in this place, but the cave was sealed by a special formation, and some powerful beings in Huaxia Kingdom thought that this was the inheritance left by human monks in ancient times, so they gathered the strength of the entire Huaxia Kingdom and wanted to break the seal. ”

"Did you succeed in the end?" Zhao Lei asked urgently.

"Hehe! It worked, but it could also be said to have failed!"

Looking at Zhao Lei's puzzled expression, Yun Rui continued: "After attacking for three days and three nights, the seal was finally broken by us, but what those Huaxia powerhouses saw next was not a powerful inheritance, but endless demon beasts!"

"Demon beasts, could it be that the demon beasts sealed in the cave?" Zhao Lei was also taken aback, he was originally looking for the inheritance, but he didn't expect to pierce the demon nest!

"Yes, I don't know how big the cave is, in short, there are a lot of demon beasts pouring out of it, fortunately, the strength of these demon beasts is not strong, plus at that time, in order to break the seal of the cave, many strong people came, that is, there are several powerful existences above the transformation realm, and there are still demon armies defending in the scorching sun forest. ”

"In the end, after several days of fierce battles and huge casualties in the Huaxia Kingdom, most of the demon beasts that poured out were finally wiped out! Only some demon beasts that were not a threat to humans were kept for human beings to study!"

At this moment, Zhao Lei finally understood why the Snow Spirit Scorpion appeared on the earth, and it turned out to be that cave that ran out!

"After the demon beasts were slaughtered, those masters of the Huaxia Kingdom wanted to continue to investigate the cave, because everyone was worried that this cave was likely to be a wormhole of the demon clan, and if the demon clan suddenly appeared from here in the future, I am afraid that the entire earth would be in danger of being destroyed!"

"After the masters of the Huaxia Kingdom entered the cave, it was very smooth at first, but after going a few kilometers deep, a few demon beasts suddenly rushed out of the cave and launched the most violent attack towards those masters, and several powerhouses of the Transformation Realm died in the hands of these demon beasts on the spot, and the rest of the people fled in a hurry under the cover of several powerhouses above the Transformation Realm. ”

"What happened later?" Zhao Lei asked!

"The strange thing is that after the humans exited the cave, those demon beasts only howled a few times at the entrance of the cave, and then returned to the depths of the cave, and did not rush out to slaughter!"

"Since this incident, Huaxia Kingdom has no longer sent people into the cave, but has only built a military base here, and set up defenses outside the cave entrance to prevent sudden attacks by demon beasts. ”

"After so many years, those demon beasts have not had any other excesses except for the occasional terrifying roar at the entrance of the cave!"

After Yun Rui finished speaking, Zhao Leizhen fell into deep thought.

How could there be such a strange cave on the earth, and there was such a powerful demon beast in the cave!

All kinds of suspicions are on the surface, a long, long time ago, maybe there were really demon clans living on the earth, but then I don't know why, these demon beasts suddenly disappeared.

Putting the doubts in his heart behind, Zhao Lei did not hide it, and told Yun Rui all the information about these four demon beasts.

After listening to Zhao Lei's narration, Yun Rui let out a long sigh, looked at Zhao Lei with a little deep meaning and said, "I'm really curious, where did you get so much news about the demon clan when you were young? If you weren't sure that you were still a human, I'm afraid I'd arrest you right now and study it well!"

"Hey, hey!" Zhao Lei deliberately smirked a few times, but did not answer!

"Don't worry! There are many people with secrets in this world, as long as you are dedicated to mankind and Huaxia Kingdom, no one will force you to tell the secrets in your heart!" Yun Rui smiled and gave Zhao Lei a reassuring look, "Besides, this is also impossible!"
