However, as the sweeping area became larger, Zhang Feng's efficiency did not decrease at all, and it was even faster than he started.

It turned out that Zhang Feng was not only in action, but also the mirage clone, the ancient tiger and leopard beast Dabai, and the alien fire Vermilion Bird, and even the World Tree, the Demon God, the Horned Demon Emperor, the Mountains and Rivers Map, and the Mechanical Race Spaceship were also involved.

During the sweep, Zhang Feng also encountered some latent demons, demon minions, etc., all of which were also killed by him, including the high-level of the Red Lotus Buddha Kingdom.

These monks not only confuse the public with demons, but also collude with demons, and even there are many demon members in their own country, who have been against Zhang Feng a hundred years ago, and finally paid the price and were directly destroyed by the country.

In the end, Zhang Feng flew to the Ten Thousand Demon Cave in the depths of the Lost Island Domain.

In the Ten Thousand Demon Cave, it has long been reduced to the hell of Shura, and the tide-like monsters and demons are pouring out from the depths of the Ten Thousand Demon Cave, trying to break free from the seal of the Ten Thousand Demon Cave and invade the beautiful world outside.

Fortunately, the major forces led by the Falling Star Palace of the Lost Island Region have already sent countless masters to suppress it here day and night.

Bang bang bang......

At this time, the sky above the Ten Thousand Demon Cave was densely packed with powerful martial artists, and they continued to pour the power of Void Breaking, Star God, and even the Cave Heaven into the seal outside the Ten Thousand Demon Cave, so as to support and repair the seal that was constantly being destroyed.

At the same time, there were countless demons that violently slammed into the seal, and even did not hesitate to use means such as self-explosion, the blown seal was crumbling, and even small cracks appeared from time to time.

Every time a crack appeared, a large group of demons immediately swarmed and rushed out of the crack.

The warriors who support and repair the seal also have an additional task, which is to kill these demons that rushed out.

There are a lot of demons, and most of them are pure-blooded, as for non-pure-blooded and some monsters, they are the main force of self-explosion, which also leads to great pressure on the warriors, even if there are many people, they are not weak, and there are a large number of casualties.

"Ancestor-level array, up!"

As soon as Zhang Feng arrived, he immediately broke out into the small universe of martial arts, suppressed the entire Ten Thousand Demon Caves, and at the same time quickly laid out one after another ancestor-level arrays, and immediately the Ten Thousand Demon Caves shook violently, bursting out with dazzling light, and then a curtain of light emerged.

The demon collided on the light curtain, and the light curtain did not move at all, even if it self-detonated, it would not help, but the energy of the impact and even the self-explosion was absorbed by the formation, constantly reinforcing the formation, and also inspiring golden lightning.

The lightning has a brilliant power and righteousness, and it is especially restrained against demons, and each one can kill a large area.

"It's Zhang Feng, Zhang Feng is really alive, and he has already returned!"

"Zhang Feng's name is what you can call?

"Well, it's the lord, the lord is mighty!"

"It's worthy of being the lord of our Lost Island Domain, as soon as he makes a move, he controls the overall situation!

Seeing this, the warriors were first shocked, but then they breathed a sigh of relief, overjoyed, and recognized Zhang Feng, and they were even more excited and full of worship.

It turned out that the island-level big forces were relatively more well-informed, so they already knew that Zhang Feng was still alive and cultivated to a great advancement, and had passed the hundredth level of the Divine and Demon Fantasy Realm, but they still didn't expect that Zhang Feng would come so quickly, and the means were so powerful.

I think that back then, Zhang Feng performed well in the Universe Selection of the Demon Palace, and the Lost Island was rewarded to Zhang Feng by the people above, and many big forces at the island level were somewhat unconvinced, and later Zhang Feng achieved better results, so they could accept it.

In the hundred years since Zhang Feng's fall, they haven't mentioned this matter again, but now, they are all very happy, because thanks to the lord Zhang Feng, otherwise once the Ten Thousand Demon Caves are lost, the Lost Island will definitely become a hell on earth.

For Zhang Feng, the lord, they no longer dared to be dissatisfied, and even became extremely proud because of this, because Zhang Feng came too timely and too powerful!

Zhang Feng nodded slightly, stepped out, and immediately passed through the large array and entered the interior of the Ten Thousand Demon Cave!

Bang bang bang......

Zhang Feng trampled into the void and walked all the way, seemingly random and unhurried, but every step could cross an unknown number of hundreds of millions of miles, and the starry sky followed wherever he passed, and countless demons and monsters exploded like fireworks regardless of cultivation or type.

"It's not good, it's the big devil Zhang Feng, he seems to have become stronger, run!"

When some demon powerhouses saw Zhang Feng from afar, they were immediately frightened and fled into the distance.

It turned out that Zhang Feng left a great name in the Ten Thousand Demon Caves back then, and there are still demons who remember him.

But back then, Zhang Feng didn't dare to really go deeper, and when he encountered a real strong man among the demons, he had to flee immediately.

Now, it's the demons who are fleeing for their lives.

And even if these demons recognize Zhang Feng and flee early, the speed is too slow, not as fast as Zhang Feng at all, they will be caught up and surpassed in an instant, and then they will burst into scum like the rest of the demons.

For Zhang Feng back then, the Ten Thousand Demon Caves were extremely huge, but for Zhang Feng now, they are very ordinary. Soon, Zhang Feng came to the end of the Ten Thousand Demons Cave and saw a huge black hole.

There is a steady stream of demonic energy gushing out of this black hole, and there are also a large number of pure-blood demons mixed in it, which is the source of the Ten Thousand Demon Cave.

Originally, this place was once suppressed and sealed by the power of the human sages, but over the years, the seal has become weaker and weaker, and now it has long since dissipated, which is why there are more and more demons in the Ten Thousand Demon Cave, and one of the most important reasons why there are still power to impact the seal.

"It's the entrance to the Demon Realm again, and this entrance is even bigger, and it's very unstable, it can only be sealed and can't be broken, it's really troublesome! It's no wonder that my human predecessors didn't destroy this entrance!"

Seeing this black hole, Zhang Feng couldn't help frowning slightly.

Some rifts and spatial nodes in the two realms can be destroyed directly, while others cannot, and forcibly destroying them may even cause the rift to become larger, and even produce other unknowable anomalies. Under the mirror lake is the former, but in front of you is clearly the latter.

"Okay, I'll seal this place again. But before that, I might as well go to the Demon Realm. Since ancient times, it has been demons that have invaded the universe where my human beings live, and I will invade them today!"

While letting the small universe kill the demons by itself, Zhang Feng thought about it, and made a decision in a blink of an eye, first quickly sealed the black hole with one by one ancestor-level array, and then immediately stepped out again, penetrated the large array, and disappeared into the black hole.

Of course, he only went to the deity this time, and the clone stayed in the East China Sea, and there is a world tree to communicate the two worlds, so he is not worried about falling or something.

"Hmm, this is the Demon Realm, it turns out to be another universe!"

Soon, Zhang Feng passed through the black hole and came to a starry sky, but this starry sky is completely different from the universe where humans live, not only full of demonic energy, but also the rules of heaven and earth are different.

Moreover, Zhang Feng had already cultivated the starry sky visualization technique and deduction to an extremely high level, and he also had a certain understanding of the origin of the universe and was very familiar with it, so he could easily feel that he had left the original universe.

He was standing in space at the moment, with a huge black hole above him, which was also the passage of time.

Not far below is a huge planet, filled with the demonic aura of Hesse, and countless demon locusts flying from the planet.

Obviously, the ancestors of those demons in the Ten Thousand Demon Caves, as well as some of the demons and monsters, are from this planet!
