In the moving labyrinth, there is only one figure running around, scurrying like a headless fly.

After encountering another dead end, Yun Fan stopped desperately and sat on the ground.

He still hadn't found a way out of the labyrinth.

After thinking for a while, he took out a jade bottle from the ring, and he didn't necessarily make any movements, and a glowing white light floated out of the jade bottle, and in that light group, there was an illusory figure.

"How exactly should this box be opened?" Yun Fan said as he took out the mysterious box and looked at the Helldemon Lord in the group of light.

The Helllord sneered, but he didn't say a word, looking like he wasn't going to speak.

Yun Fan frowned, he didn't talk nonsense, with a flick of his fingers, a wisp of soul power immediately popped out, shot into the light cluster, and then slammed into the body of the Dark Hell Demon Lord.

The Helllord couldn't help but howl in pain as if he had been whipped by a whip, and his entire body curled up and trembled slightly.

"My temper and patience are limited, and if you're really useless, there's no point in me keeping a piece of waste. Yun Fan's fingers tapped lightly on the box and said lightly.

"However, I believe you know the difference between dying painfully and dying happily. Yun Fan glanced at him, and above the palm of his hand, a few wisps of soul power were beating slowly, eager to try, "You think about it yourself." ”

The expression of the Helllord kept changing, and his eyes were gloomy, as if he was thinking about something.

"Smack!"

Another soul attack slammed into the Helllord's body, making a crisp sound.

The Helllord roared in pain again.

"I don't have much time for you to think it through. Yun Fan's indifferent voice sounded.

The Helllord lowered his head, his eyes full of resentment, but when he raised his head, the deep resentment had been hidden in the depths of his eyes.

"I'll tell you how to open this box, can you let me live?" asked the Helllord in a deep voice.

"You don't have the capital to bargain with me right now. Yun Fan said lightly, "You just need to know that if I can't get out, you will definitely not be able to get out either, and besides, you will definitely die in front of me." ”

The Helldemon Lord was silent for a while, and then slowly spoke: "I'll tell you how to open this box, but if you can really escape, you must let me go, otherwise, even if I want to die, you don't want to get out alive!"

Yun Fan frowned, and after a while, he nodded soothingly, "If I can go out, even if I let you go, what's the matter?"

"But only if you don't hide anything, otherwise, you know the consequences. Yun Fan added another sentence later, his voice was cold, and the killing intent was awe-inspiring.

After getting Yun Fan's answer, the Helldemon Lord nodded and said, "This box is made of Tianxin Nan wood, you should have heard of this kind of wood, right?"

"Tianxin Nanmu?" Yun Fan was stunned, his brain was running extremely fast, and he soon found the record of Tianxin Nanmu from his memory, "Is it the kind of Tianxin Nanmu that can inherit soul power among the very few objects?"

"Yes, it is the Heavenly Heart Nanmu, this kind of wood has a very special structure, and it is one of the few woods that can inherit soul power. The Helllord nodded, "And that pearl is Flounder, and it is also a rare pearl that can inherit the power of the soul. ”

"In other words, this box must be opened by a soul master?" Yun Fan said with some astonishment.

The Helllord nodded, "Yes, I was the one who opened the box. ”

Yun Fan couldn't help but shake his head and laugh, if this Dark Hell Demon Lord didn't say it, I'm afraid I don't know how long it would take him to think that this thing would actually need soul power to open.

It's also a loss to his soul and soul double cultivation, otherwise, there is really no way to take this box.

"How do you open it?" Yun Fan asked, holding the box in his hand.

"First of all, inject soul power into the box, there is a mechanism in the box, and use the soul power to slowly push the mechanism. "The Helllord is guiding Yun Fan Dao.

Now the two of them are grasshoppers on the same line, one is prosperous and the other is lost, Yun Fan is not afraid that this guy will dare to calculate anything against him.

Yun Fan injected soul power into the box, and on the mysterious box, those lifelike symbols faintly flashed with an imperceptible light.

Yun Fan's mind moved, in the center of the box, there was indeed a mechanism, he controlled his soul power to slowly push the mechanism according to the method that the Hellish Demon Lord said, and it didn't take long to hear a 'click!'.

On the top of the box, a hole slowly cracked, and the round flounder dragon was about to fall, but fortunately, Yun Fan used his soul power to support the flounder dragon and slowly injected soul power into it under the reminder of the Hellish Demon Lord.

The already dazzling Florosaurus exudes a faint brilliance at this time, with a unique hazy beauty.

Under Yun Fan's careful control, the flounder slowly fell into the groove in the center of the box below, and the soul power flowed as expected.

"Click!"

After a flash of white light flashed on the top of the box, the lid above it dropped sharply, and then slid out to the side, revealing the scene inside.

After opening the mysterious box, Yun Fan cast his eyes on the box.

Inside the box, a folded note and a delicate key lay quietly.

When Yun Fan took out the note and key, the Helldemon Lord looked at the two familiar things, and his eyes couldn't help but show a complicated look, the last time he saw these two things, he didn't know how many years ago.

Yun Fan rubbed the delicate key with a slight coolness, but he didn't see anything famous, so he had to shift his attention to the piece of paper.

Gently opening the folded paper, Yun Fan looked at the crooked handwriting on it, and the corners of his mouth couldn't help twitching slightly, it was really the style of the mysterious mansion owner.

"Live to die. Although he had already learned the contents of this paper from the Hellish Demon Lord before, when he saw it with his own eyes, Yun Fan couldn't help but gently read out the four big characters that were not easy to read.

Hearing Yun Fan pronounce these words, a look of obscurity flashed in the eyes of the Helldemon Lord.

"Live to die, live to die, live to die. Yun Fan's mouth kept muttering these words, and his eyes were a little blank.

What exactly do these four words mean?

The Hellish Demon Lord looked at Yun Fan's stunned appearance, and the corners of his mouth couldn't help but sneer, they were the same back then, turning over and over, and chanting these four words with a god, it was like going mad.

In the end, there was still one person who didn't understand the meaning of these four words, but drove a few people crazy.
