When Gao Yun was meditating and refining his spiritual energy, a crisp bell suddenly rang in his ears, and then the voice of the old man in gray came over in a calm tone.

"I'm a little sorry, but it's already a month, so you'll need to beat your first opponent to qualify for staying here. ”

Hearing this, he exhaled a breath of turbidity, and Gao Yun slowly opened his eyes.

At this time, his face was already scruffy, a little vicissitudes, and his clothes were in tatters.

However, the muscles around his body are clear and well-textured, creating an extremely well-proportioned beauty, and between his eyes, there is a look as sharp as a sword blade, which is obviously a big leap in strength compared to when he first entered the Treasure Hall!

At this time, he got a drop of the inheritance of the demon dragon's essence blood, his physique has undergone earth-shaking changes, and the dragon's aura has also absorbed nearly eighty percent, and in terms of cultivation, he has also faintly touched the threshold of the double peak of the earth and underworld!

Slightly sorry to the old man in front of him, Gao Yun asked, "May I ask senior, what is the content of the monthly level?"

The old man nodded slightly, and said leisurely: "Actually, it's not difficult, there will be a demon dragon to fight against you in every level, but the level of the demon dragon will gradually increase with time, the first time is the triple of the underworld, the second time is the sixfold of the underworld, and the third time is the peak of the underworld, jump at triplet intervals, as long as you can defeat it, you can obtain the qualification to continue cultivating in the treasure hall." ”

After a pause, he then twisted his beard and said: "However, it should be noted that the time consumed by the level battle is counted in your total time in a month, that is to say, if you consume too long when you pass the level, then correspondingly, the remaining time for cultivation will be reduced accordingly, plus you still need to pass the corresponding trial before cultivating, and the time will be even more urgent." ”

Hearing this, Gao Yun nodded slightly, here, time is undoubtedly more precious.

He suddenly thought of a question: "By the way, senior, if I pass three levels in a row, then the total cultivation time will be four months?"

"Three levels in a row?" the old man's eyebrows raised slightly, and his lips moved, "That's naturally four months, what's wrong?"

He secretly thought in his heart, this kid has a lot of appetite, and he is only in the double realm of the underworld, but he thinks that he has passed three levels in a row. You know, the third level is the pinnacle of the underworld.

Gao Yun had vaguely guessed some of his thoughts from the old man's expression, but he didn't care, because what he was thinking about at this time was other things.

"Because when I came in, the elder didn't tell me that it might take so long to enter here, so my wife may not know yet, and I'm afraid that she is in a hurry, and there is no way to contact her......"

According to his previous thoughts, he could only take a few of his favorite soul recipes and select a few weapons and equipment just like entering the place where the academy stored soul recipes and weapons, and at most he could only comprehend it for more than ten days, but he didn't expect it to be like this. If it's more than ten days, it's not a big problem, but if you have to stay for several months, I'm afraid that Zhu Ling outside will inevitably be worried.

The previous two consecutive trial battles were too tight, so he didn't have time to think about this problem, but now that he slowed down a little, he immediately thought of Zhu Ling.

"You don't have to worry about this," the old man understood what Gao Yun meant, and said with a slight smile, "There is a layer of slow-flowing magic circle shrouded here, which has the effect of slowing down the flow of time by ten to one, that is to say, if you cultivate here for four months, it is equivalent to twelve days outside." ”

"Slow-Flow Array?" Gao Yun was shocked for a moment, "There is actually such a magical Circle, so if you continue to cultivate inside, wouldn't you be able to gain ten times more time to cultivate than outside?"

Glancing at him, the old man twisted his beard and said slowly, "The idea is good, but it is not feasible. First of all, under the condition of slow flow of time, you can comprehend the soul trick or do things like selecting weapons and equipment, but you can't break through the realm, so you will encounter a bottleneck that can't be eliminated later, and you have to go out to break through, and in the case of the realm can't break through, the time you stay in it is very limited, after all, the monthly level is there, the enemy is getting stronger and stronger, and your cultivation is standing still, and you have to go out after all. ”

"Then after I go out to break through the realm, wouldn't it be good if I come in again and continue to cultivate?" Gao Yun scratched his head and wondered.

"Hmph, do you think this treasure hall is a cabbage?" the old man snorted coldly, "Every Ghost City Lord can only enter once in his life, so it is impossible for you to enter after you break through." ”

"You can only enter once in your life?" Gao Yun couldn't help but sigh, a look of regret on his face, "Why?"

"This is a demon dragon treasure house that your ancestors were only allowed to enter after signing a contract with the Demon Dragon Emperor, but as one of the most ancient and distant forces in the Netherworld, the Netherworld Demon Dragon naturally has many conditions for entering its treasure house, otherwise, wouldn't your Netherworld Imperial City already dominate the Netherworld. ”

Gao Yun smiled embarrassedly, he didn't expect that there was such a deep relationship in this.

However, the "unification of the underworld" mentioned in the old man's last sentence was said to his heart, and he did have such a mind in his heart.

"I was abrupt. Sticking out his tongue, Gao Yun immediately said, "Time is precious, I'll start the level battle now." ”

When the old man heard this, he didn't reply, and waved his sleeve slightly.

Gao Yun immediately saw a flower, and found himself in an extremely flat and vast granite square, this square, surrounded by a slight mist, seemed to be boundless.

In front of him, a figure appeared, and the opponent should be him.

However, to his slight surprise, this opponent actually looked exactly like himself!

In the space, the voice of the old man immediately sounded.

"In each level, your opponent is a virtual version of himself, who can use all the soul tricks you have learned, and his strength will increase with the number of levels. Now, the battle begins!"

Facing the opponent in front of him, it seemed that he was fighting against himself, thinking of this, Gao Yun suddenly burst into excitement, and a raging black soul power flame instantly ignited around his body!

When Gao Yun was fighting in the Treasure Palace, on the other side of the inner city, there was a deep pavilion that went straight underground.

Unlike ordinary pavilions, which are built layer by layer, this pavilion is built in a deep pit that is sunken.

The first entrance to the pavilion is level with the ground, and then it is difficult to imagine how this pavilion was built just by looking at the appearance, because it has completely subverted traditional architectural theories.

If someone stands on the edge of the pit and looks inside, they can only see that it is dark inside, but they cannot know how deep it is.

From the deep pit, there is a trace of cold air, which makes people feel creepy and dare not approach.

This is the temple of confinement in the inner city used for punishment and imprisonment.

On the second floor of the Confinement Temple, in a small, dark room.

A middle-aged man was sitting cross-legged on the cold iron blue ground with his eyes closed, although his eyes were closed and he seemed to be calm, but his expression was the same as the ground, the same cold iron blue. Between the tightly furrowed eyebrows, there was a strong perverse and fierce aura.

"Shadow Huang, Shadow Heaven, Shadow Heaven, one day, I want you all to die!" he cursed as he muttered, trembling slightly from his excitement.

This person is the elder who clashed with Yinghuang in the inner city before and almost blew the inner city into a mess, Yinghuang's second uncle, Yingchen Tian!

Previously, he was counting on his son Ying Feng to humiliate Ying Huang in public, but he didn't expect to be beaten by him, and when he tried to suppress it, he was unfortunately hit by his eldest brother Ying Wutian, not only did he not hurt Ying Huang, but he lost his position as a law enforcement elder, and was also punished here for half a year.

Thinking of this, he couldn't help but grit his teeth, clenched his fists, and slammed them on the ground.

Secretly depressed, suddenly there was a "crunch" nearby, and the door of the confinement room opened.

"Who?" said Ying Chentian looked up suddenly.

When he saw the figure in front of him, he was stunned!
