Wukong said: "Just now we entered the 'ghost realm' of the nightmare, so we fell asleep and struggled in our dreams. But the nightmare has been removed, and it is natural that the dream should wake up. ”

The Bull Demon King said: "I see! But I was scared to death by the old cow, and my mother-in-law almost beat me to death." ”

The Jiao Demon King couldn't help laughing and said, "I can't imagine that the eldest brother is actually a person who is afraid of his wife?"

The Bull Demon King palpitated, and said, "You don't know that my mother-in-law is very capable, and I am not her opponent." ”

Wukong suddenly found that there was already a light in front of him, and it seemed that he was about to sail out of the sea area of the North Underworld.

"There is light, have we already left the Northern Underworld?" the Jiao Demon King hurriedly urged the warship and headed towards the light.

Wukong put aside the matter of Rulai for the time being, but his heart has become more determined, even if Rulai is so powerful, he still has to compete with him, if he doesn't fight, he will eventually turn into ashes and repeat the mistakes of the past. As it comes, the name weighs on Goku's heart like a mountain.

The warship finally sailed out of the Northern Underworld Sea, but this sea water was still full of dead air, and Da Luo Jin Immortal did not dare to enter it, and in an instant, the Yuan Shen and the Three Flowers and Five Qi would be killed by the dead air. The source of this dead air seemed to be ahead, and several people looked at it and saw a huge island, there was an iceberg in the distance, but the whole island was different from the situation in the sea, full of life, and the trees were verdant.

"Look, the ships have come over! Let's go to the island. The Jiao Demon King said loudly.

"Let's go, the source of this dead gas may have something to do with this island, let's go to the island and take a look. Goku stood on the mast.

After sailing at sea for more than a month, he finally saw an island and was able to go ashore, which made the Bull Demon King very happy.

There are not many cultivators who came to the North Underworld this time, and they probably thought that the death of the Northern Underworld was related to a great war in the Middle Ages, so they wanted to come and get some treasures. However, this treasure is not easy to catch, and some small sect warships were directly destroyed at sea, and people died in this dead sea.

The Jiao Demon King drove the warship towards the island, and after about half an hour, it finally landed, and several people jumped onto the shore, and the Jiao Demon King collected the warship.

Wukong saw a broken stone tablet standing on a reef on the island, which was already colorful and old, with ancient fonts written on it.

"Battle the Mystic Realm?" Wukong said word by word the words engraved on the stone tablet.

The Bull Demon King is the most well-informed, and when he heard Wukong's words, he couldn't help but exclaim: "Battle Mystery Realm? Are you sure you're not mistaken? This is an ancient script, and I can't even recognize the old cow." ”

Wukong smiled and said, "That's right, it's the battle mystery realm, you kick my ass if you make a mistake!"

The Jiao Demon King said, "Big brother, is there anything wrong with this battle in the mysterious realm?"

The Bull Demon King said, "Of course there's a problem! I don't know if you've heard the name of the God of War Xingtian?"

Wukong and the Jiao Demon King were also taken aback, and Wukong asked, "Could it be that this battle of the Mysterious Realm has something to do with Xingtian?"

The Bull Demon King bowed his head and said: "Of course it's related, this battle mystery realm was founded by Xingtian, and all the people living in it are his clansmen." In ancient times, Yan Huang and Chiyou competed for hegemony, and after Chiyou was defeated, it was rumored that Xingtian also died with him. I didn't expect that the War Mystery Realm was hidden on the side of the Northern Underworld, and looking at this appearance, it seems that the Great War in the Middle Ages broke out here. But some people say that Xingtian and Zhizhi are not dead, Yan Huang let them go, and they really died in the Middle Ages War. ”

Wukong glanced around, but found some broken magic weapon materials on the ground, all of which had lost their luster and divine effect, and turned into scrap metal.

"What is the secret realm?" the Jiao Demon King couldn't help but ask.

"The Secret Realm was founded by some ancient powers...... In ancient times, it was a golden era of cultivators, all races fought for hegemony, the heavens and the earth were shaken, and after the great tribulation of the opening of the heavens, the great tribulation of dragons and phoenixes, the great tribulation of the lich, and then there was the battle between Yan Huang and Chiyou, and finally the battle of the gods and the saints competed for hegemony, and an era experienced five murders. In ancient times, there were many great powers, such as Xingtian, there was the War Mystery Realm, and Gongsun Xuanyuan the Great had the Xuanyuan Secret Realm, the Immortal Phoenix had the Colorful Secret Realm, and Zulong founded the Nine Dragons Secret Realm. However, there are still traces of these secret realms in the Middle Ages, and they disappeared completely after a great war in the Middle Ages that was not recorded by history. The Bull Demon King pondered for a moment before he told the story, he also listened to what his master said, and he wrote it down after hearing and seeing.

When a few people were amazed, the warship of Erlang God Yang Jian, who had encountered it on the sea, also docked, and he jumped off the boat and glanced at a few people.

"Brother Yang Jian, it's really fateful, why don't we join forces and seize the treasure on this island together?" asked the Bull Demon King.

"Thank you for the friendship of the Bull Demon King, Yang Jian has long been used to being alone, so he won't go with all the Taoist friends, just go by himself. Yang Jian said, and led the big black dog that could stand up to the person's shoulder, and was so angry that the Bull Demon King's nose was crooked, this guy is really too arrogant, too temperamental.

Wukong said: "Big brother doesn't have to be angry, we have just arrived in this mysterious world, and we don't know what is in this secret world, and it's not too late to compete with Yang Jian after we find out the situation." ”

The Bull Demon King nodded and said, "What my brother said is very true, let's go, let's not delay here, hurry into the depths of this island to see what is there." This island looks so big from the outside, I really don't know how Xingtian opened it up, this kind of power is really terrifying!"

Wukong and others also think that these secret worlds are also known as the Void Secret Realm, which are purely opened up with mana, floating in the endless void, and generally do not appear, especially after the Middle Ages, the secret world has almost never appeared again. I don't know if it was destroyed in the war or what's going on, it became a mystery, and there is no historical record of the great war in the Middle Ages.

However, it was said that Yang Jian came to the war mystery realm this time, because there was a causal implication in the underworld, he sensed that there was something related to him in the North Sea, and he was very skilled, so he asked the grass head god to build a warship, and then went out to sea alone with the roaring dog to find it.

Wukong, the Bull Demon King and the others no longer lingered on the periphery of the secret realm, and set up clouds and went to the depths.

There are no fierce beasts in this secret realm, it seems very peaceful, only some small beasts, which do not hurt people, and they are far away when they see them.

It is said that Wukong, the Bull Demon King and others took a boat from Beiju Luzhou to the North Underworld, until the danger encountered in this battle mystery world, there is no need to say more, and it is said that the three brothers and the dragon whale are flying to the depths of the war mystery world.

The Void Secret Realm is the foundation of a great force, and the rumors of the God of War Xingtian have long since fallen, but this secret realm still exists, but the people of Xingtian can no longer be seen.

Wukong faintly felt that something terrible seemed to be suppressed under this secret realm, and that death qi was emitted from this terrible existence, which made him feel incredible, who could have such a powerful power, and could pollute the entire North Sea water.

"There was a city ahead, and they all went in. The Jiao Demon King looked at it, and saw a huge city in front of him, and a black tower was erected in the center of the city, which seemed to have been cut horizontally by the heavenly sword, and a large section was broken, and the other section did not know where it went.

A secret world, is equivalent to a small world, people in it to be self-sufficient, of course, need to build a city, grow food, etc., in fact, this secret world also has a role, that is, to provide incense and wish power, it is rumored that there are hundreds of millions of Buddhas in the secret world, chanting Buddhas every day, providing him with a steady stream of strength. And the Sanqing Dao Ancestor and the others, naturally also have a powerful secret realm, there are countless believers in the secret realm, sincerely pray, provide incense, to establish a secret realm, you need to have the power of the Mixed Yuan Golden Immortal Triple Heaven Creation Realm.

This huge city is the core of the War Mystery Realm, but it is already full of broken walls, and after a medieval war, it has been dilapidated, and the ancestors of the War Mystery Realm are rumored to have long since fallen.

A few people pressed the cloud head and entered the city, this time there were not a few cultivators who came to the North Darkness to investigate, even some secular monastic sects also sent people, these secular monastic sects also have powerful masters, otherwise where can they gain a firm foothold?

"Go to the Black Tower!" Wukong said, and when he arrived in this city, he could no longer fly, not because his mana was suppressed, but because there was an ancient prohibition in the city.

Probably because Xingtian felt that it was too uncomfortable to be in the city, so he set up a ban so that no one could fly in the city.

Wukong saw some people from Buddhism, and some people from the Immortal Dao, and a number of Oriental stars came from the twenty-eight constellations, such as Jiaomu Jiao, Kang Jinlong, Di Tu Raccoon, Fang Ri Rabbit, Xinyue Fox, Tailed Fire Tiger, and Kei Water Leopard.

Buddhism has twenty-four heavens, as well as some Arhat Venerables, but there are a lot of people from the heavenly court, and Wukong also saw some old acquaintances.

It can only be said that "it's not that enemies don't get together", and the five emperors of Wuyue Zhengshen Huang Feihu, Chongheihu, Wen Ping, Cui Ying, and Jiang Xiong are also among them.

However, now the situation is a bit chaotic, everyone is holding back, when Wuyue Zhengshen and the Seven People of the Eastern Star see Wukong and the Bull Demon King and others, they all have a fierce look in their eyes, and they want to take a weapon and kill it. Wukong and the others smiled, but they didn't bother with them, turned the street, changed to another street and went to the Black Tower, the Black Tower is the center of the city, there may be secrets, everyone is walking in that direction.

The Jiao Demon King scolded: "Good Dragon Didong, I actually met these enemies here, and they teamed up with Heavenly Court to make things difficult for us, so what should we do?"

The Bull Demon King said: "Just let them come and go, I don't care about the people of the heavenly court, Lao Niu! ”

This Bull Demon King has a magic lamp in his hand, and he knows that Wukong has the imitation whip of beating the gods, which is the most suitable to deal with the people of this heavenly court, although it is a bit exaggerated to fight one by one, but it is not impossible for them to suffer a big loss, most of these people in the heavenly court are too high-eyed, but the combat power is really not very good, one by one let the heavenly court be fed full of fat intestines, although the mana is there, but the battlefield has been neglected for a long time, how can it be compared with Wukong and other big demons who have been fighting almost every few days?

Wukong smiled: "Brother Niu is so arrogant, but you don't have to worry about the second brother, just come to Tutun when the time comes." ”

The dust on the street is very thick, and Wukong and the others try to take it as lightly as possible, so as not to make the dust fly and make it difficult to breathe.

"What do you say Xingtian is doing to build a black tower here? I feel that the anger on the black tower is very heavy, as if countless people have washed it with blood, and it has all been washed black. "Whenever the Jiao Demon King looked up at the black tower, he felt a palpitation in his heart.

"Isn't the blood red?" the Bull Demon King smiled, "Lao Jiao, you are really uneducated, you need to study more." ”

Wukong couldn't help but laugh and said, "Big brother, blood will turn black after coagulating for a long time. Moreover, I also have this feeling of the second brother, the black tower seems to be extremely weird, there is a sense of anger, since I entered this city, I feel uncomfortable, gloomy. ”

The Bull Demon King was choked, touched his head, and said, "Ahh

The Bull Demon King has a big personality, not as careful as the Jiao Demon King and Wukong, of course he can't feel it, he just thinks about how to clean up the Wuyue Zhengshen for a while, and find them to fight again, and he has to pull that Yang Jian to fight, let him know that he can't be too high-eyed, otherwise there will be no good end. This old cow does have the capital of pride, and his mana has comprehended some mysteries of cause and effect in the cause and effect realm of Da Luo Jin Immortal, but he is still looking for someone to fight to contaminate cause and effect, and he doesn't know if he is really stupid or great wisdom.

The four realms of the Immortal Dao, the true immortal is a primary immortal, basically not into the stream, only when he reaches the Taiyi Golden Immortal, will he be taken seriously, which god canonized in the heavenly court is not the level of the Taiyi Golden Immortal?

"Be careful for a while, and try not to conflict with people, so as not to be fished in troubled waters and knocked on a stick. These people look fairy-like, but they're actually extremely thick and dark. "Wukong has experience in dealing with immortals, so at this moment, he warned the Bull Demon King and others not to make enemies with others unless they had to.

The Bull Demon King said: "Don't worry, brother, big brother can save it!"

Wukong said in his heart that I'm afraid that the one who doesn't know the most is you, and when he sees Yang Jian for a while, he will look for someone to fight with red eyes, although Yang Jian's temper is arrogant, but Wukong and the others ignore it, and the Bull Demon King wants to drill the tip of the horns and compare with him, which is really a headache.

The group of four talked as they walked, and in a short time they had reached the bottom of the black tower.

The black tower was built on a huge square, and it was so large that it was enough to reach the sky in half of the tower.

"It's really blood on the Black Tower! It's the blood of the gods, the demon king, and the Buddha!" The Jiao Demon King's fur exploded at once, and he felt the bloody breath rushing to his face.

The Bull Demon King was also rarely steady, and muttered: "That's right, there is the holy breath of the Buddha, the fierceness of the demons, and the immortal aura of the gods...... The blood of the Buddha should be golden, but after so many years, the blood has turned black. During the period of the Great War of the Middle Ages, history was blank, an unknown era, and there may be many secrets hidden here. ”
