"Okay, very good, just do as you say!" After listening to Lu Xuan's explanation quietly, the Daoist couldn't help but applaud.

In fact, Lu Xuan's method was really simple, and after listening to it, the Daoist also knew that he had ignored the simplest things.

The solution was to eliminate everything they could think of, and what was left was almost the one they couldn't remember.

In terms of Lu Xuan and the memory of the Daoist of Opportunity, it can almost reach the point of unforgettable. So the thing that I can't remember is almost certainly the key to open the door.

"The stone walls, the puppet people, the passage floor, these are all common things since we entered the passage, and the shape does not match the appearance of the keyhole, we can remember it, so we can rule it out." Lu Xuan said, picked up the blood-red dagger in his hand and wrote these on the black stone door, and then drew a big cross vigorously, indicating that these things had been excluded.

The Daoist nodded, and then began to speak: "Each oil lamp has nothing special except for the special refining method, and it can also be remembered, and it will not be." ”

Lu Xuan also smiled approvingly, and then also wrote down the word oil lamp, and then continued to draw a cross.

"The things in the three passages are basically the same, and it's pretty much what we just said we excluded, so what else are we missing?" Lu Xuan looked at the few words written on the black stone door, and couldn't help frowning and thinking deeply.

Ji Daoren also kept touching his forehead on the side, bowing his head for a while and shaking his head for a while, obviously thinking of something, and was immediately eliminated by him.

Since entering the passage, everything he has seen and heard has been combed through by Lu Xuan over and over again in his mind, trying to find something special in it.

But no matter how he reversed the memories of the past, he always felt that there was nothing missing, and the memories in his mind could be said to be able to recount all the experiences completely and clearly.

"What the hell is missing?" Lu Xuan couldn't think of an answer, and began to look around, hoping to find something inspiring.

The stone walls around are the same, gray-black without any special light, the ground is also a piled up passage, and the oil lamps are still burning quietly.

"Huh? Is that? Suddenly, Lu Xuan noticed an item lying in the corner, which suddenly gave him a special feeling.

Lu Xuan walked over, picked up the things on the ground, took them in his hands and observed them carefully, there were two blades, one side had a sharp point, and the other side was indeed an obvious section.

"This is part of the puppeteer's weapon that you destroyed just now." Seeing that Lu Xuan was holding the broken blade and bowing his head and was silent, he couldn't help but speak.

However, when the words of the Opportunity Daoist just fell, a wave of enlightenment rose in the hearts of Lu Xuan and the Opportunity Daoist at the same time.

"That's right, it's the hilt!" The two of them looked at the broken sword held in the puppeteer's hand with this thought in their hearts at the same time, and sure enough, the hilt of the broken sword was exactly the same shape as the keyhole.

Lu Xuan and the Daoist were overjoyed, and the key they had been looking for was not far from their feet.

The two couldn't help but glance at each other, and their faces were quite difficult.

However, as soon as they looked away from the hilt of the broken sword, it was as if something had crept away from their memories.

"Hey, I seemed to suddenly remember something just now, but now I don't remember it?" The Daoist looked at Lu Xuan, who was staring at him, and couldn't help but say with some doubts.

"I feel the same way, what the hell is going on?" Lu Xuan nodded and agreed with the statement of the Opportunity Daoist.

It's like suddenly remembering something you want to know, and then forgetting it in the blink of an eye.

"What is it that you forgot in the blink of an eye?" The Opportunity Daoist frowned and said, this feeling made him very unhappy, as if his memory had suddenly been siphoned away.

"It's a strange feeling, it shouldn't be like this." Lu Xuan was also confused at this time, he picked up the things in his hand and patted his palms lightly while thinking.

"Hey, what's it in your hand?" At this moment, the Daoist discovered the broken sword in Lu Xuan's hand and couldn't help but speak.

"What do I have?" Lu Xuan looked down suspiciously, and suddenly fell to the spot as if he had been struck by lightning.

It seems that he and the Daoist of Opportunity had discussed this broken sword just now, and then found that the key was the hilt of the broken sword, but after they looked at the hilt of the broken sword together, they all forgot about it.

"Sure enough, the hilt of the broken sword was manipulated!" After seeing the broken sword in Lu Xuan's hand, the Daoist immediately remembered what had happened before.

Obviously, the Divine Emperor had performed a spell on the hilt of the broken sword, and as long as he looked at the hilt of the sword and then looked away, a small part of his memory would be emptied.

And this little memory that has been emptied is extremely small, so it is not easy to detect at all.

This spell should only exist on the hilt of the sword, or the position of the hilt should be the core area of the spell, the entire long sword has a spell, but after Lu Xuan cut off the long sword, the tip of the broken sword was disconnected, so that they were not affected.

Fortunately, Lu Xuan has always held the tip of the sword in his hand, so that they can constantly remember that the hilt of the sword is the key through association!

"Senior, what do you think we should do now?" After Lu Xuan knew the power of the sword hilt, he no longer looked at the sword hilt, but looked at the opportunity Daoist and said.

"This spell is small and doesn't have any attack power, but it's so powerful that I can't even find a way to break it." The Daoist shook his head slightly.

"We can't just be stuck here, can we? A solution has to be figured out! Lu Xuan said with a wry smile, having come to this point, if it is rumored that they are trapped by a small spell, it will not make people laugh off their big teeth.

"That's right, although the spell of the God Emperor is powerful, no spell is unsolvable." The Daoist nodded and agreed with Lu Xuan's statement, and he was not willing to give up like this.

Both of them had one thought in their hearts, the true secret of the God Emperor had not been solved, how could they be willing to end here.

"Judging from the test just now, if we don't look at the hilt, we won't be affected, and in that case, then we don't look at it." Lu Xuan looked at the broken sword in his hand and thought for a while, and then said.

"It's okay not to look at it, but the key is that we still have to get it, if it is in normal times, we can still use our spiritual power to identify the location, but the God Emperor has already dealt with the puppeteer, so that our spiritual power can't detect it, if we don't look at it, we can't even tell where it is." After listening to Lu Xuan's method, the Daoist said the difficulties he was about to face.

Lu Xuan knew that what the Dao people said was the truth, and he didn't know what method the God Emperor used to detect it with their spiritual power, and there was a blank space in front of him, whether it was the corpse of the puppet man or the black stone gate, it could not be detected at all.

And if you look at it, your eyes will definitely touch the hilt of the sword, even if you look at it out of the corner of your eye, after the test just now, it will be affected by the magic of the God Emperor.

"In that case, let's try this method!" Lu Xuan said, took off his coat, and then threw it towards the puppet man's corpse.

The coat was thrown away by Lu Xuan, and it quickly unfolded in the wind, and the entire coat was propped up by the wind, and then slowly fell on the puppeteer's body, and part of the puppeteer's body was covered under the coat, and the hilt of the sword was in it.

"Hey, it works!" The Daoist tried to look at the position of the coat, and since the hilt of the sword was covered by the coat, although he looked at the position of the hilt, he saw the coat.

Without the influence of the sword hilt technique, the Daoist laughed, stepped into the position of the puppeteer in one step, and then grabbed the hilt of the sword with the help of his coat.

However, at this moment, the body of the Daoist suddenly froze, and then he turned his head and said to Lu Xuan: "Lu Xuan, what are you still standing there doing, don't you look for the key quickly!" ”

“……”

Hearing this, Lu Xuan couldn't help but be a little speechless, it turned out that touching the hilt of the sword like this would also be affected.

This shows the power of the Divine Emperor's spell!

"Senior, do you know how to clear your heart?" Lu Xuan looked at the Daoist who was obviously holding the hilt of the sword in his hand and looking around, and couldn't help but speak.

"What kind of fame, how can I not be able to do such a simple mental method as the Pure Heart Mantra?" The Daoist couldn't help but pout, although he had doubts in his heart, he still answered Lu Xuan's question affirmatively.

"In that case, ask the seniors to recite the Pure Heart Mantra for a while, and then empty your whole body, think of yourself as a blank piece of paper, and just obey my command." Lu Xuan smiled slightly, and then continued slowly, "After successfully opening the door of the passage, I will explain all this to my seniors." ”

"Okay, I'd like to see what you kid is up to!" The Daoist thought about it, and then agreed to Lu Xuan's request.

Soon, the eyes of the Daoist became blank, and the whole person seemed to stand in place as if he was stunned like a piece of wood.

Seeing this, Lu Xuan knew that the Daoist had completely emptied his body, and then it was time for him to act.

"Grab what you're holding, then walk forward, and stop when you hear me stop!" Lu Xuan thought for a moment, and then began to give orders.

As soon as Lu Xuan's words fell, the Daoist began to walk forward step by step.

"It's really effective!" Looking at the actions of the Daoist of the Opportunity, Lu Xuan was overjoyed in his heart, knowing that he was not far from success.

Soon, under Lu Xuan's hard work, the Daoist successfully put the key into the hole in the black door.

"Very good, next, twist/move it!" Lu Xuan's expression remained unchanged and continued to give orders.

"Click!"

Under Lu Xuan's command, the Daoist turned the key, and soon heard a crisp sound, as if a certain mechanism had been successfully touched.
