As soon as Emperor Huawu Immortal finished speaking, the ancient stone gate in front of him shook violently, as if the earth was shaking, and finally opened. The moment the stone gate opened, a monstrous demonic aura rushed into his face, and the brilliant Shenwu Key flew back into the hands of the Huawu Immortal Emperor.

"What, it's such a strong demonic aura, could it be that it's the Demon Realm over there?" Huawu Immortal Emperor and Wu Lai were both extremely surprised. After all, the fairy world does not have such a strong demonic aura, it may be the demon realm.

The two looked at each other.

"Wouldn't it really lead to the Demon Realm here?" Wu Lai said in his heart.

"Let's go inside. "Huawu Immortal Emperor is naturally a master of art and bold. Even if he really went to the Demon Realm, Huawu Immortal Emperor was fearless. He is a martial arts supreme who has survived the divine tribulation, and he can compete with the Qingxuan Immortal Venerable, and of course he will not be afraid of the powerhouses of the demon world.

Wu Lai naturally wouldn't be afraid, not to mention that there was the strongest person in the immortal realm like Huawu Immortal Emperor next to him.

Emperor Huawu Immortal and Wu Lai stepped into this ancient gate. The world was spinning, and the two of them seemed to have stepped into the abyss of darkness and came to another world, which was a dim world, full of demonic energy, which made people shudder. If it is an immortal with low cultivation, the mind will be affected.

"Senior Huawu, do you think this will be the Demon Realm?" Wu Lai asked.

Huawu Immortal Emperor shook his head: "It shouldn't be." If this was the Demon Realm, Emperor Shenwu would have mentioned it in the inheritance, but there was no explanation. Bendi guessed that this was just a small world. It's just that how there is such a strong demonic aura is unknown. ”

"That's it!" Wu Lai asked no more.

The two of them moved forward at breakneck speed. With their strength, they can cross a galaxy in one step.

It didn't take long for the two to hear a screeching voice.

"There is actually the breath of an immortal. ”

"It's been a long time since I smelled an immortal. ”

"Eat them, eat them and we'll go to the next level. ”

Soon, a group of black shadows pounced on the two.

"Look for death!" Huawu Immortal Emperor snorted coldly, and all the black shadows burst open and disappeared. The strength of this group of black shadows was comparable to that of the Nine Heavens Xuan Immortals, but in front of the Huawu Immortal Emperor, they were like ants, and they couldn't withstand the Huawu Immortal Emperor's cold snort at all.

"What the hell are these black shadows?" Wu Lai asked.

These black shadows seem to have no substance, but they are tangible, and they must be a living being, or a life form.

Huawu Immortal Emperor muttered, "They should be demons, real demons, different from demon cultivators. In fact, Emperor Huawu Immortal was very shocked in his heart, he didn't expect that there were demons in this world.

"It's actually a real demon?" Wu Lai was a little surprised.

What kind of existence the demon is, no one can tell. At least he's a life form. Demon cultivators in the demon cultivation world, although they cultivate demons, they are not demons, they are still human beings, they are just cultivating demon cultivation techniques. Those demon cultivators in the Demon Realm are not real demons.

Demons should be said to be a unique state of life between heaven and earth. Wu Lai even suspected that the Supreme Demon Lord was the ancestor of the demon, the first demon to be born.

"You know?" asked the Huawu Immortal Emperor strangely.

You must know that the existence of demons is only known to old antiques like Huawu Immortal Emperor in the immortal world, and ordinary immortals don't know it at all.

Wu Lai nodded: "Yes, I have met him in the demon cultivation world, he was originally just a demon cultivator, he performed a soul sacrifice, and finally became a demon, the demon power is monstrous, and the strength is extremely strong." He is the Great Demon King of Yunlin, who provoked a war between the two realms of the Cultivation Realm and the Cultivation Demon Realm, and was finally killed by me. ”

Huawu Immortal Emperor had naturally heard of the Yunlin Great Demon King, who was the culprit who provoked the war between the two realms, and was finally killed by Wu Lai.

"I see. ”

There are rivers and mountains in this world, but it is very dim and gives people an extremely uncomfortable feeling. However, the two of them didn't care, along the way, they got a lot of very good refining materials, and there were some medicinal materials that the fairy world didn't seem to have, almost all of them were of that kind of dark attribute, and they gained a lot. The refining materials and medicinal materials are naturally as good as possible for Wu Lai.

Along the way, the two encountered a lot of demons, Wu Lai caught some, easily extracted their memories, and got a lot of information after synthesizing. It turns out that this place can be called the Demon Domain, extremely vast, dominated by demons, originally there were other life in the Demon Domain, but all of them were exterminated by demons. Later, an immortal known as Emperor Shenwu entered this demon domain, he was extremely powerful, and killed many demons, but he did not exterminate the demons in the demon domain. He also brought some people in, and some of them were killed and devoured by the demons, and the demons obtained the cultivation methods of these people and became more powerful. Later, Emperor Shenwu never appeared again, and those immortals did not come in again. The demon domain is divided into three layers, and there is a passage between each layer, of which the first layer is some demon emperor-level demons, there are very few demons at the lower level, and they are basically eaten by the demon emperor, and the second layer is mainly the demon at the demon lord level, and the demon emperor generally does not dare to enter the second time, and the third layer is the demon at the demon emperor level, because the third layer of demon qi is the strongest, so it is occupied by the demon emperor level demon. The Immortal Monarch-level demons didn't dare to go to the third layer, otherwise they would be eaten by the third-layer Demon Emperor-level demons. The law of the jungle is vividly reflected in the Demon Domain. In addition, although the passage between the layers is not a retrograde channel, the Demon Emperor at the upper level generally does not go to the lower layer, after all, they don't look down on the demonic qi there at all.

"That's exactly what happened. "Huawu Immortal Emperor and Wu Lai basically understood the situation in the Demon Domain.

The deeper the Huawu Immortal Emperor and Wu Lai went, the more demons they encountered, all of them were in groups, and they were getting more and more powerful, and later, they were even more overwhelming demon shadows, all of them were demon queen periods, like thousands of troops galloping, sweeping everything, even the powerful immortal monarch had to avoid its edge. However, for these weak Demon Hua Martial Immortal Emperor and Wu Lai, they were too lazy to kill, and no matter how many demons there were at the Demon Emperor level, they would not pose a threat to them. They kept going deeper, not knowing how far they went, and finally found the passage from the first layer to the second layer in the memories of those demons.

"This is the passage from the first floor to the second floor. ”

The two entered the passage without hesitation.

The world swirled, and the two entered the second layer of the Demon Domain through that passage. The demonic qi of the second layer is indeed much stronger than that of the first layer, and those who are not strong-willed are easily affected. Generally speaking, immortals are extremely unsuitable, and their strength when they come to the Demon Domain will be discounted. However, Emperor Huawu Immortal is a martial arts cultivator, and his will is extremely strong, and it does not have much influence on him here, while Wu Lai is a former god of death, who has been in the demon cultivation world, and he doesn't care even more.
