In those years when I was a mortal and a demon

"Okay! Don't hold back later, you must use thunderous means to get rid of those beast kings as soon as possible!" Now that Lu Yuan, who has the highest level of cultivation, has spoken, Shi Xiao can only agree.

"This is natural, the dragon will clear the way!" Lu Yuan once again pointed at the group of beasts in front of him.

Thousands of black sword blades gathered into a black dragon that was dozens of feet long and rushed towards the location of the Beast King.

Among the beasts blocking the path of several people within a radius of several hundred feet, even though there were many Demon Guard-level ferocious beasts, they were unable to stop Lu Yuan from attacking with his peak strength in the late stage of divine transformation. He was instantly swept away by the demon dragon. And empty.

Such a massive blow made Shi Xiao and others feel shocked again.

Not to mention that the bat-winged youths were only in the early stages of the generals. Even if Shi Xiao, a rough-skinned and thick-skinned man with extremely strong natural defense, was in the middle stage of the general stage, there was no guarantee that he would be able to take on the stone demon.

"That's..." Lu Yuan's eyes narrowed.

A hundred feet ahead, there was a piece of light green mist, which was dozens of feet wide. Inside was a huge monster with a strange appearance.

This beast looks strange, and its six to seven-foot-sized body looks like a puddle of green mud. It was covered with pits and holes of different sizes, but in the middle there was a huge meat ball like a head rising slightly. There are no organs on it except two blood-red eyes.

At least Lu Yuan didn't see anything like a mouth or a nose.

All in all, this beast looked really disgusting. Even Shi Xiao and the others looked weird, but after seeing this guy, they all had creepy expressions on their faces.

"What the hell is this!" Willow Thorn, whose head was covered with thorns, was first surprised.

"I haven't seen it before, but why is there only one? Shouldn't there be five?" The bat-winged young man glanced at the light green mist with cold eyes, and he could see the situation clearly.

Lu Yuan couldn't help but glance at Shi Xiao, who smiled bitterly at Lu Yuan, obviously not knowing the origin of this beast. Then Lu Yuan cast an inquiring look at Qing Fly and Zhu Hye, and the two guys shook their heads.

Seeing that no one knew the origin of this beast, Lu Yuan immediately suppressed his excitement.

It’s actually a sky-swallowing beast!

In the ancient demon world long ago, the reputation of the sky-swallowing beast was no less than that of the demon-sucking ant, one of the major natural disasters in the demon world.

If the number of magic-sucking ants is frightening, then only one of these sky-swallowing beasts appears. Once discovered by the primitive demons who know its power, it will definitely be killed because this thing is too terrifying.

The Sky-Swallowing Beasts were not originally called this name, but existed as early as the beginning of the Demon Realm, but at that time they were a branch of the ordinary Mire Beasts in the Demon Realm.

It was only when the Mother Borer later wreaked havoc on the demon world that this branch was infected with the aura of the Mother Borer.

Under normal circumstances, once an ordinary demonic insect turns into a borer, its strength will greatly increase, and its reproductive capacity will also increase dozens of times.

But this beast is slightly different. It actually inherited the terrifying devouring ability of the Mother Borer. The more energy it devoured, the more powerful it became.

And with this ability, a beast of the Saint Ancestor level appeared in a short period of time.

Even among the most powerful primitive demons in the demon world at that time, there were many saint ancestors who fell into the blood of this beast, so they gave this beast such a horrifying name.

Later, after the Mother Borer was sealed, the primitive demons began to deal with this beast.

In the end, regardless of whether they were infected or not, the entire mire beast clan was directly wiped out, causing them to completely disappear in the history of the demon world.

Until now, who knows how many thousands of years later, apart from the primitive demons, probably only those saint ancestors know something about this beast.

Lu Yuan would recognize this beast, naturally he knew it through the ancient magic crystal core of the blood flame.

And just now, after carefully understanding this part of the information in the blood flame crystal core, Lu Yuan also learned a piece of news that surprised him.

Now this sky-swallowing beast is actually inextricably linked to the blood flame.

Back then, Xueyan accidentally discovered the larvae of this beast while traveling. As a primitive demon, he naturally knows how terrifying this beast is.

But Xue Yan was also a very brave artist. At that time, he was only a god general. He took advantage of the fact that the sky-swallowing beast was still in its larval stage and planted a brand in its soul, making the sky-swallowing beast his. Spirit worm.

Of course, given the evil reputation of this insect in the early days of the demon world, Xueyan was given the courage to bring it back to the clan.

If the seniors from the original demon clan discovered it, they would probably destroy the Sky-Swallowing Beast and the Blood Flame immediately without blinking an eye.

Therefore, Xueyan simply never returned to the gathering place of the original demons, but wandered around. And they constantly kidnapped various magical beasts or low-level demons for them to devour.

But later, seeing the sky-swallowing beast slowly growing to the level of a god general, and needing to swallow more and more energy, Xue Yan was worried that it would be discovered sooner or later if it continued like this.

At that time, Saint Ancestor Yuan Cha was about to invade the human world, so Xue Yan suddenly thought of an evil idea.

He wanted to take the opportunity to bring the Sky-Swallowing Beast to the human world, so that he could be devoured by the Sky-Swallowing Beast without restraint, so he joined the service of the Holy Ancestor Yuan Cha.

But later, when he was about to take the Sky-Swallowing Beast and follow the Holy Sacrifice Army from the Demon Realm to the Human Realm, the Holy Ancestor of Yuan Cha accidentally noticed something strange.

After all, the Sky-Swallowing Beast was infected by the Mother Borer, and it carries the aura of the Mother Borer. Every saint ancestor in the demon world had gone to the Land of the First Seal to suppress those mutated borers, so they were naturally very sensitive to this.

Seeing that it was about to be exposed, Xueyan could only put the sky-swallowing beast into an endless sleep through the restrictions planted, and found a secret place deep in the Two Realms Mountain to hide it.

After the Saint Ancestor Yuancha searched to no avail, he gave up the pursuit because the holy sacrifice was imminent.

In order to get rid of suspicion, Xue Yan could only follow the army into the spirit world. At the same time, he was also prepared to wait until the Holy Sacrifice was successful and once the incarnation of the Holy Ancestor Yuan Cha left, he could find an opportunity to return to the Demon Realm and secretly bring the Sky-Swallowing Beast to the Human Realm.

It's just that people's calculations are not as good as God's calculations. Xueyan didn't expect that he would stumble in the human world. So much so that Lu Yuan later took away the Ancient Demon Crystal Core, and was destroyed by Han Li in Kunwu Mountain.

Lu Yuan refined the ancient demon crystal core of blood flame, which naturally contained some aura of blood flame.

When Lu Yuan first arrived in the demon world, he used the body of the holy demon to drive away the beasts. The trace of blood flame breath it leaked just awakened the Sky-Swallowing Beast that had been sleeping for a long time.

However, Xueyan's death also weakened the restriction placed on the Sky-Swallowing Beast. Naturally, it was impossible for it to surrender to anyone. After noticing the breath of blood flames, it quickly moved away from Lu Yuan.

Now that the Sky-Swallowing Beast appears here, it must be hungry after years of slumber.

Everyone had clearly felt that there were several different beast king auras here before, but now there was only one of them left. This further proves that most of the beast kings in this beast wave have been devoured by it.

"Fellow Taoist Yuan has traveled around a lot and has seen a lot. Could it be that he recognizes this beast?" Shi Xiao asked when he saw that Lu Yuan looked at the sky-swallowing beast a little strangely.

"I haven't seen it either, but this guy actually has five different auras existing at the same time. It's just that the other four are extremely weak now. If you don't distinguish carefully, you can't detect it at all. It's really strange!" Lu Yuan quickly expressed some opinions. , cover up the past.
