After more than an hour, Lin Fan had no choice but to stop. In this hour, they had almost walked through the third layer, but they had never met anyone higher than Lin Yuyu's Spirit Dance Light Shadow Technique.

"Brother Lin Fan, why don't we go to the fourth floor!" Lin Yuyu suddenly spoke.

Shaking his head slightly, Lin Fan put away his smile and said solemnly: "No, not to mention that we can't enter the fourth layer, even if we can go in, any volume of magic in it is forbidden and we can't resist it, and we must not take risks." ”

Sighing, Lin Fan continued: "Look for it again, if you really can't do it, just find a scroll of Heavenly Rank low-level magic tricks." ”

In the mist, although there were many tricks, none of them could arouse Lin Fan's interest, and in desperation, the two could only agree to leave temporarily and come back tomorrow.

Outside the Spirit Jue Hall, Lin Fan looked at this majestic building, shook his head with a wry smile, and was about to leave when a dark golden metal door attracted his attention.

The metal door was closed, and there was no monitor or sensor cannon from Lin Fan's vision, but when Lin Fan looked at the metal door, a coolness rose behind him, and he subconsciously released his spirit, and his spiritual power probed towards the metal door.

"The door of the Spirit Secret Hall here is forbidden, and the juniors leave quickly, otherwise they will bear the consequences!"

The old man's voice suddenly sounded in Lin Fan's ears, with a huge and powerful spiritual coercion, forcing Lin Fan's spiritual power back into the spiritual world, but it didn't hurt Lin Fan at all.

But the terrifying coercion still made Lin Fan snort and take a few steps back uncontrollably, but Lin Yuyu held it in time to avoid sitting on the ground.

Raising his head, his blue-black pupils flashing with surprise, he looked at the dark gold metal door again.

An old man stood in front of the metal door, very tall, with silver threads fluttering slightly. The black pupils flickered with dark gold from time to time, and the skin was like a baby, as if he felt Lin Fan's gaze, and turned his head to look. "Still not leaving?"

Lin Fan only felt an irresistible feeling appear in his heart, and it spread rapidly. Taking a deep breath, he stiffened his head and asked the old man. "Sir, what are you talking about the forbidden door?"

The old man retracted his gaze and said after a long time: "These are not the places you can touch, leave quickly, otherwise if something happens, I can't do anything." ”

"Old man, is there something forbidden in the forbidden door, or is there a scroll of magic recipes forbidden?" Lin Fan saw that the old man didn't want to say more, and hurriedly said the guess in his heart.

The old man's eyes shot out a dark golden lightning, and he didn't see any movement from him, so he came to Lin Fan and Lin Yujue. "How do you know these things? Who told you that?"

Lin Fan's face turned pale, and he clearly felt that the temperature of the surrounding air instantly cooled, as if he had come to Shura Hell, and a killing eye came out of the old man's body, locking on Lin Fan.

Lin Fan was sure that as long as he said the wrong word or made a superfluous move, he would be instantly killed by the old man in front of him. Don't dare to be careless, forcibly condense your spiritual power, and tell everything that happened just now and your own guesses.

The old man was silent for a while, his eyes were filled with dark gold light, he grabbed Lin Fan and Lin Yuyu, and strode towards the dark gold metal door.

The metal door trembled and swirled, and pieces of metal disintegrated and reassembled, revealing the pitch-black space within.

Lin Fan had been releasing his spiritual spirit, and at this time, his eyes were difficult to see in this pitch-black space, and his spiritual power naturally turned into a detector-like existence and spread forward.

But Lin Fan was surprised to find that this space seemed to have the effect of blocking spiritual power, and it could not move forward if it only spread a foot away.

"If you don't want to die, you can reclaim your mental power. The old man's voice sounded in his ears, Lin Fan was stunned for a moment, and the next moment he found that his spiritual power was being swallowed up by the surrounding space bit by bit, and it was gradually speeding up the devouring speed, and the frightened Lin Fan hurriedly retracted his spirit.

The whirring wind kept ringing in his ears, and Lin Fan probably estimated that the old man had traveled at least thirty kilometers with them, and he didn't go in one direction at all. Suddenly, a ray of white light appeared in front of him, and Lin Fan's eyes lit up, knowing that he was about to reach his destination.

Sure enough, after the old man entered the white light, he put down Lin Fan and Lin Yuyu.

closed his eyes uncomfortably, stretched out his hand to support Lin Yuyu, opened his eyes, and looked around.
