On the bluestone wall on the right side of the ninth layer, a crack suddenly appeared. When I got closer, I realized that this was not a sword mark on the bluestone wall at all.

"Space?" A slight shock flashed in Xu Han's eyes, this crack was clearly a crack in space, but because the crack was too shallow and narrow, it was not very obvious.

Suddenly!

Rumble!

There was another huge roar, and another crack in the space was added.

At this time, Xu Han suddenly thought of something, and his eyes narrowed slightly: "Could it be that it has anything to do with the tenth layer?"

Huanglong Tianfeng said that the tower of Tongyuan has a tenth-layer storage zài. But there is no passage on the ninth floor, which means that the tenth floor cannot be reached in a normal way at all. Moreover, when Huanglong Tianfeng talked about the tenth layer, he only said that he had leaked his mouth and looked very nervous. Explain that not everyone in Huanglongfu knows about the tenth layer of the storage zài. It is likely that only the lord of the mansion, Huanglong Tianyang, and his son Huanglong Tianfeng know.

In this way, the tenth floor is completely different from the other nine floors.

"If that's the case, then let me help you. Xu Han seemed to understand something, a meaningful smile appeared on the corner of his mouth, and then his right hand pulled out the long sword behind him like lightning, and a demonic blood light shone in the space.

"Draw your sword, cut your sword. With Xu Han's low groan, the long sword in his hand slashed down, and suddenly, an extremely powerful blood-colored sword curtain pounced out, slashing towards the crack in the space.

Whew!

The blood-colored sword curtain ruthlessly tore through the space, leaving a pitch-black path in its path, tearing open an incomparably huge hole in that spatial rift without any suspense, and a terrifying black aura permeated from it, making people palpitate.

The opening of the space quickly repaired itself, and peace was restored. A flash of surprise flashed in Xu Han's eyes, because he saw that where the gap in the space appeared, there was a trace of white gas gushing out, more and more.

The white gas slowly drifted through, gradually forming a white mist. Xu Han's heart trembled slightly, and he said secretly: "This is not ...... The entrance to the secret realm?"

After thinking for a moment, the corners of Xu Han's mouth raised slightly: "I see, this is the tenth layer!"

Without further words, Xu Han stepped out and stepped into the white mist, and at this time, an invisible suction force pulled him to another space.

"This is ......" Xu Han looked at the things in front of him with some surprise, and there was a hint of exclamation in his tone: "The tenth layer!"

The secret realm on the tenth floor of the Tower of the Abyss is another world entirely!

Xu Han stood on the edge of the valley, looking into the distance, and sighed with emotion in his heart: "It's like a dream." ”

Golden plains, golden forests, golden mountains, golden clouds, golden sun! Yes, this is a golden world! Every place and every corner of this world exudes incomparable light. What makes people feel amazing is that this light is not dazzling, as if shining into people's hearts, there is a warm current in the heart, and the whole body conveys a feeling of numbness, which is very comfortable and refreshing.

Xu Han closed his eyes and took a deep breath, and the incomparably rich Heaven and Earth True Yuan seemed to be able to penetrate into his body with his breath. This feeling, as if as long as you live here and breathe the air here, you can quickly improve your sword cultivation.

"Such a secret realm is not something that a master of the True Infinite Realm Sixfold can open up. Xu Han whispered in his heart, full of curiosity about this tenth layer.

The secret realm has been a mystery for a long time. When he was in the Sword Dust Continent, some people said that as long as they reached the True Nothingness Realm, they could open up a secret realm. But Xu Han is now a True Realm powerhouse, and he is in a world where the True Realm is strong, and in his cognition, the True Realm does not have the ability to open up a secret realm.

However, the secret realm seems to be everywhere. Whether it is the Sword Dust Continent or the Martial Realm, there are many secret realms, and the origin of the secret realm is also unknown.

Then, if this secret realm on the tenth floor, if it wasn't opened up by the Huanglong Mansion itself, there would only be one possibility left - before Huanglong Tianyang built the Tower of Tongyuan, this secret realm was stored underground, but with the construction of the Tower of Tongyuan, this secret realm was excavated.

"If my guess is correct, there must be a huge secret hidden in this secret realm. Even, Xu Han suspected that Huanglong Tianfeng did not honestly confess to him, he said that the tenth layer was the biggest secret of Huanglong Mansion, at first Xu Han thought that this "biggest secret" referred to the secret treasure of Huanglong Mansion Yinyuan Sword and the unknown guardian of the secret treasure - the only True Boundless Sixfold Master of Huanglong Mansion.

But now it seems that the secret realm of the tenth layer is a huge secret in itself, and it is more than just the secret of the Yellow Dragon Mansion.

"Hmph, boy, how long are you going to be here in a daze!"

Before Xu Han's thoughts were finished, he was interrupted by an old and deep voice, his eyes narrowed slightly, and he sneered: "I dare you to wait for me here." Smiling, Xu Han jumped down the valley and stood firm on the golden plain with his feet.

In front of Xu Han's eyes, there was an old man in a red robe, his silver hair was full of silver, long and messy, and he was casually draped down. His face was full of wrinkles, but there was a hint of anger between his eyebrows, and his eyes were shining.

Hearing Xu Han's smile, the red-robed old man snorted coldly: "Otherwise, do you think you can find out here?"

Xu Han raised his eyebrows, "That spatial gap was also deliberately left by you?"

"I should say that I showed you the way to get here. ”

"So, you already knew that outsiders had broken into the Tower of the Abyss?"

"Yes. ”

Xu Han's brows couldn't help frowning, and a look of incomprehension flashed in his pupils. The secret realm is almost equivalent to another world in nature, and if this person has never left here, it is impossible for him to perceive what is happening in the outside world.

The red-robed old man seemed to see Xu Han's doubts, and said with a smile: "Boy, I know what you are wondering about. It is true that I cannot learn what is happening in the outside world here by my own ability, but there are so many secrets hidden in this secret realm that even I cannot understand. "Speaking of which, the red-robed old man has only been in this secret realm for only a month.

"Since you know what's going on outside, and you don't make the slightest move, it means that you don't care about the life or death of the Yellow Dragon Mansion, and you don't put everyone's lives here, in this case, you can completely leave me alone, cultivate here with peace of mind, and dig out the secrets here, I think, I may not be so easy to discover this place." "The old man in the red robe didn't know what was happening outside through his own ability, which meant that there were other ways to gain insight into what was happening in the outside world in the secret realm, then, Xu Han deduced that he should also know about the killing of Huanglong Tianyang.

"That's right, but ......" A cold glint flashed in the eyes of the red-robed old man: "I don't want to leave you alone." There was a hint of imperceptible killing intent in his cold tone, but this trace of killing intent still made Xu Han aware of it.

Xu Han couldn't help but sneer: "So, you still want to kill me?"

The red-robed old man raised his eyebrows, with a smile in the corner of his eyes: "That's right, I originally planned to leave you alone and cultivate here with peace of mind." But your talent is terrible. It's just a true realmless quadruple sword cultivator, but he can slash Tianyang with one sword, and he can also retreat from the hands of the two masters of White Blade City. From the first floor to the ninth floor, almost no one can stop you, and of course, that's not what makes me murderous about you. ”

After a pause, the red-robed old man continued: "Your cultivation time at the ninth layer has only been ten days, but your sword cultivation has been promoted from the fourth level of the True Void Realm to the fourth peak. This rate of progress cannot be left alone. "Separately from the speed of killing people who leapfrog and cultivating fast, the old man in the red robe felt that there was nothing to be afraid of, after all, he was sitting on a golden secret realm. But when the two were combined, it would be terrifying. A master who can kill people beyond the level, the speed of progress is still fast, if he is left alone, in ten days, he will definitely be able to stand out from the crowd. Even if he excavated all the secrets of the Golden Secret Realm, he was afraid that he would not be able to compare.

"Could it be that others have made rapid progress and offended you?" Xu Han felt that the other party's theory was very funny, and his cultivation speed was fast, which was his business. First, he has no grudges with the other party, and second, he doesn't plan to take the initiative to provoke the other party. It would be ridiculous to use this as an excuse to kill him.

It's a pity that many people are like this, and they can't see others well. Even if he is not doing badly, as long as others are better than himself, he is not happy.

"When I say offended, that's offended. The red-robed old man sneered: "I said I want to kill you, that is to kill you, even if I don't give you any reason, you will only have the life of being killed." ”

Hearing this, Xu Han couldn't help but sneer: "It depends on whether you have that ability." Ten days ago, Xu Han didn't have any confidence. Now, he is already at the peak of the True Boundless Realm Quadruple Realm, even if the other party is a True Infinite Realm Sixfold powerhouse, he dares to fight.

"Heh, this is quite backbone, but unfortunately, in front of me, it's just not enough. There was a hint of sarcasm in the eyes of the red-robed old man, and then, he looked at Xu Han and said, "Boy, before you start fighting, you should report your name." ”

"Xu Han. Xu Han smiled faintly: "What's the matter? A 'high-profile' powerhouse like you is also interested in me, a loose person?"

"Although he is a loose person, his talent is really amazing, which I have to admire. The eyes of the red-robed old man flashed slightly: "Boy, do you know who I am?"

"Well, I've heard a little. The corners of Xu Han's mouth raised slightly: "It seems to be the guardian of the secret treasure of the Yellow Dragon Mansion, the Yellow Dragon World." ”

"Then I don't have to introduce myself. After saying that, Huang Longtianxia's body released a violent burning true qi.
