Outside the Great Array. The Claw Demon Emperor, who stayed to wait, listened to the earth-shattering sound of fighting in the valley, and felt a powerful aura, and the Claw Demon Emperor was extremely shocked in his heart.

In the past three years, he has been staying here, and the valley has never been calm, almost every once in a while, there will be a vision of heaven and earth when he broke through.

In addition, every two months, there would be violent fights, and sometimes even terrifying sounds like the roar of evil spirits, so that he could not be quiet for a while.

Of course, these are nothing, the important thing is that every time the sound of a fight sounds, the aura coming from inside will be several levels stronger than last time.

At the beginning, those aura was many and low, and it was just a group of seventh or eighth level masters, and he didn't care at all.

But now, the aura has become less, but it is stronger, and he clearly feels that each breath has reached the peak of the ninth level, and there are more than a dozen of them.

This made him have to worry, what kind of monster did that breath come from, in three years, it was promoted from the eighth level to the ninth level, and in another three years, it would be promoted to the tenth level.

No, at this rate, maybe in a year, or a few months, those ninth-level peak breaths would break through to the tenth-level.

"What can I do, I'm the only one here now, and I can't even send someone back to ask for help. The Claw Demon was anxious, although he was also a tenth-level Demon Emperor powerhouse.

But he has only been in the tenth level for a few hundred years, and his strength is equivalent to a one-star martial saint of the human race, and it is okay for the last tenth level who has just been promoted, but in this tenth level, there are still a few helpers of the ninth level, so he can only escape.

Of course, as a tenth-level Demon Emperor-level master, as long as he opened his mouth, he could mobilize countless armies to come over, but when they were stationed here when they discussed it before, they didn't expect such a thing to happen, so they didn't send troops over.

After all, Long Feitian's strength is too weak, not even level seven, for level ten masters, as long as they are out of the big array, one finger can destroy ten times.

There is simply no need to send any more troops.

Besides, they also want to be face-saving, the dignified Thirteen Demon Emperor masters, plus tens of millions of troops, but they couldn't even take down a few human youths, so they can only sit here and defend it, what a shame it is.

If the army is sent, it means that these troops will know about them, and once the word spreads, they will not become the laughing stock of the entire Demon Domain.

But now, every time he hears the sound of a fight inside, the claw demon is like those unknown monsters hitting him, which makes him extremely uncomfortable.

Thankfully, the fight only lasted for more than half an hour before it faded away, much to the relief of the Claw.

But this time he really made up his mind, he must find two more helpers, otherwise he will really let the conspiracy of the humans inside succeed and escape, and his life will not be guaranteed.

The claw demon was frightened, frightened by the increase speed of Long Feitian's corpse ghosts, but it wasn't that Long Feitian wanted to scare him, there was really no way.

The Corpse Charm is different from the Brake Charm, which can devour all the souls at once, and then slowly digest it to improve its strength.

But the corpse ghost can't do it, it has to devour a batch, digest those energies, and after the body evolves, it can devour another batch.

At first, those corpse ghosts just devoured the corpses of those demon armies, and naturally there would be no fight, but after devouring the corpses, their strength was not very strong, and the strongest was only level nine, and there were only a few.

The others were all level eight, although there were quite a few of them, there were thousands, but they couldn't help Long Feitian at this time.

So the dragon flew to increase their strength.

And whether it's a corpse or a chakra, the only way to increase your strength is to devour, devour corpses, devour souls, or devour companions.

The corpses and souls left by the demon army before were all devoured by them, and Long Feitian had to let them devour each other, and this kind of fight could pick out the most powerful.

Although the movements of the fight, Long Feitian could completely use the formation to cover them, but that had to disappear the energy stored in the large array.

Now this large array has devoured tens of millions of troops of the demons, and the demons are not stupid, knowing that it is impossible to break through with numbers, they will definitely not send any more soldiers, without a large army, there is one less main way of energy source.

Therefore, Long Feitian had to save energy, because he didn't know if the demon clan would come to attack them again one day, if the energy was not enough, the big array would be easily broken.

In one room, an old man looked at a middle-aged man below with a majestic face, and said in a deep voice, "Bai Yu, what did you find?"

"Back to the Sect Master, the situation has been confirmed, there are indeed human beings in the Demon Domain, the number is about twenty years old, they are all very young, and there is a formation master among them, his formation attainments are very high, I estimate that he should have reached the level of a grandmaster. The middle-aged man said in a deep voice.

"A formation master around twenty years old?" the old man frowned and said, "How is it possible, how can a formation master be so young?"

"This ......" the middle-aged man hesitated and said, "Maybe he is not only in his twenties, but his appearance is young, when I went, they were already trapped in a valley in the outer city of Bloodlight City, where there was a Demon Emperor-level master of the Demon Clan, I didn't dare to approach, so I didn't see them at all." ”

"Since you didn't see them, how are you sure that there are twenty of them, and they are still very young?" the old man looked at the middle-aged man with a puzzled expression.

"They suddenly appeared in the Demon Domain three years ago, and they first appeared in Maple Leaf City, when they were pursued by the armies of Maple Leaf City and several nearby cities because they killed the bloody brother of the Maple Leaf City Lord, and many people have seen them. The middle-aged man said respectfully.

"They are indeed very young, and in addition to killing the demons in some small villages, when they see the demon squad on the road, they either use the formation to dodge or use the formation to kill, and rarely do it themselves. ”

"There are only about a thousand people in the demon team, and the strongest one is only level seven, if they are strong, they don't have to be so complicated at all, and they can be killed directly, so I guess their strength is not very strong, and they will definitely not exceed Emperor Wu. ”

When the old man heard this, he didn't speak again, but frowned and pondered, and the middle-aged man didn't bother, and after a long time, the old man asked again: "You said that they were trapped in a valley outside the Blood Light City, and the demon clan also sent a demon emperor-level master to guard them, what does this mean? Why didn't the demon clan kill them?"

"It's not that the demons don't want to kill them, it's that there is no way to kill them at all. The middle-aged man explained: "The formation masters in that team of young people are too accomplished in formations. ”

"The large array he arranged killed tens of millions of demon armies before and after, including nearly 100,000 masters above level 7 alone, as well as more than 100 level 9 masters and a beginner level 10 Demon Emperor master. ”
