"Who are you?" Du Fan glanced at Guo Huaifu deeply and suddenly asked.

"I think the seniors should have guessed a few points, the owner of that cave is the ancestor of the younger generation. Guo Huaifu smiled bitterly and said a sentence that made Du Fan stunned.

"What? Ancestor!"

Du Fan's heart shook violently, he never thought that he would be able to inadvertently make such a big oolong for the other party before he came here.

Du Fan felt that this series of things was too coincidental, first of all, Guo Huaifu believed that he was a foundation building monk, and got fifteen treasure remnants, and now he came to this treasure hiding place again, and blocked the other party, so all of this may be the reason for Guo Huaifu's preconceived ideas.

If the other party knew his true details, I'm afraid he would even have the heart to commit suicide.

"Well, I have expected this for a long time, and since you have admitted it yourself, I will no longer embarrass you, as long as you can help me open the cave smoothly, it is not impossible to spare your life. Du Fan nodded slowly and said pretendingly.

"There is one more thing, I implore my seniors to agree!" Guo Huaifu was slightly relieved when he heard this, but his expression moved, and suddenly he seemed to think of something, and his heart was horizontal, and he immediately hugged his fists and bowed, and spoke solemnly.

"Say it. Du Fan glanced at Guo Huaifu.

"There is a secret technique of inheritance in the cave mansion, which is the main practice of the ancestor of my Guo family, this exercise is not my Guo bloodline, and the younger generation implores the seniors to give up this exercise.

Of course, if the seniors are interested, they can also make a copy, and as for the other items in the cave, the seniors can take it. Guo Huaifu took a deep breath and said cautiously.

"Since this exercise is the secret method of inheritance of your Guo family, it is reasonable to make such a request, I agreed to this matter, but when the time comes, Li still has to take a look at it first, if I am really interested here, I can't say that I will have to copy a copy." Du Fan just muttered for a while, and then agreed with a full mouth.

"There is no problem in this matter, thank you seniors!" Guo Huaifu finally breathed a sigh of relief, his face was happy, and he hurriedly thanked him.

"Okay, you and I have been delayed here for a long time, let's go. Du Fan nodded, then turned around and walked straight in the direction of the lake.

Seeing that the direction Du Fan was walking was exactly where the cave was located, Guo Huaifu sighed lightly, and the last trace of luck in his heart disappeared in an instant.

When the two came to the lake, before Du Fan could make a move, Guo Huaifu spoke first: "There is naturally no problem for the seniors to dive into the bottom of the lake, but the younger generations are lowly in cultivation, and I am afraid it will be a little difficult to do this." ”

"Don't tell me you've never been to that cave before. Du Fan glanced at Guo Huaifu and said expressionlessly.

"Of course not, the juniors have a water avoidance magic tool on their bodies, and they will be used later, so as not to misunderstand the seniors, this is said in advance. Guo Huaifu didn't dare to slack off, and immediately explained to Du Fan.

"Well, I see, you can take it out. Du Fan nodded, without much expression.

Seeing that Du Fan didn't care, Guo Huaifu breathed a sigh of relief, moved his arm, and quickly took out an oval bead the size of an egg from his cuff.

This pearl is black all over, like ink, and the glow is faintly flowing under the moonlight, which has a bit of a mysterious appearance.

"What is the name of this magic tool?" Du Fan seemed to be a little interested, and couldn't help but look at it twice, and then asked.

"This magic tool is called the water repellent bead, and if you carry it on your body, you can separate the lake water, and with this bead as the center, the space with a diameter of a few zhang will not be invaded by the lake water, just like a bubble, and the younger generation will be safe and sound in it. Guo Huaifu saw that the other party seemed to be a little interested, so he introduced it in detail.

"Well, this thing is really mysterious, okay, you lead the way. Du Fan said noncommittally.

"Yes. Guo Huaifu agreed, then no longer hesitated, walked a few steps forward, and when he approached the lake, his body jumped, and then plunged into the lake with a "poof".

Du Fan's eyes fell, and the moment he found that the other party fell into the water, the surface of the lake seemed to be forcibly pressed down by an invisible thing, and it was instantly separated in all directions out of thin air, until Guo Huaifu's body was completely submerged in the lake, and the lake surface gradually closed up.

Du Fan was amazed in his heart, and immediately his thoughts dispersed, and he swept over, and found that sure enough, as the other party just said, Guo Huaifu was in a bubble with a diameter of about one zhang in the water.

Du Fan smiled slightly, his figure flickered in an instant, and instantly appeared under the surface of the lake, at this time, his body was also shrouded in a layer of bubbles, and the surrounding lake water did not soak through his clothes, as if he himself was a water-repellent droplet.

"Let's go. Du Fan said lightly.

Guo Huaifu was obviously not surprised that Du Fan could show this ability, and after hearing the other party's commands, he immediately agreed, and then without saying a word, his body moved, and he swam in a certain direction deep at the bottom of the lake.

Du Fan has been following closely behind Guo Huaifu not far away, so far, the other party has not played tricks with him, and the place where this person walked is exactly the same as the route recorded on the treasure map.

About half an hour later, the two of them were in front of a stone mountain at the bottom of the lake, and at this time, Du Fan and Guo Huaifu were already standing together, both in the bubbles that were opened by the water droplets.

This stone mountain is not big, dozens of acres in circumference, about 100 zhang high, if it is placed outside, it is a small hill at most.

On the mountain wall in front of Du Fan and the others, there was a large stone door about a wide and tall one, which was tightly closed, and it was possible to judge that this door was unusually hard and heavy just by looking at it, faintly giving people the illusion that it could not be opened.

"Senior, this is the entrance to the cave. Guo Huaifu glanced at Du Fan cautiously and said in a low voice.

"If I make a move, this door will be ruined, so use your method to open it. Du Fan said lightly.

"Yes. After Guo Huaifu nodded, he took out an object from the cuff again, which was something similar to a token, composed of bluestone material, the size of a palm, and it was engraved with some peculiar patterns, which seemed to be a bit good.

Guo Huaifu didn't talk nonsense, and immediately took two steps forward, came to the stone gate, and buckled the stone tablet in his hand in a groove next to the stone gate.

"Wait a minute, senior, at most, the stone door will open on its own. Guo Huaifu was worried that Du Fan had concerns, so he took the initiative to explain to Du Fan.

Du Fan nodded slightly, didn't say anything, just narrowed his eyes slightly, and looked at the bluestone gate in front of him with a solemn expression.

Sure enough, as Guo Huaifu said, after the stone plaque was embedded in the groove, about eight or nine breaths of time had passed, and there was a low roar from the stone mountain, and then the entire stone mountain trembled slightly, and after a while, the two doors slowly opened in a "boom" sound.

To Du Fan's surprise, as the two stone doors suddenly opened and closed, the lake outside the cave did not rush in as he had imagined, but at the edge of the cave entrance, as if there was an invisible barrier, separating the lake from each other.

"Senior, there is a kind of water barrier at the entrance of the cave, so the lake outside cannot be immersed in it, but the seniors don't need to worry, this is just a low-level prohibition, and it has a blocking effect on the flowing water alone, but it has no effect on us human monks. Guo Huaifu saw that Du Fan seemed to be a little surprised, so he took the initiative to say so.

"yes, I see. In fact, there is no need for Guo Huaifu to say more, after Du Fan's divine thoughts were swept, he already had some judgment, his eyes flashed, and he suddenly took a big step forward, and the next moment, he was in the cave behind the stone gate.

Guo Huaifu followed without saying a word, but the moment before he entered the cave, he took out the stone tablet in the groove.

After a few breaths, the stone door at the mountain wall closed again with a low and muffled "boom".

For these, Du Fan didn't care too much, if he wanted to go out, the thick stone gate that seemed indestructible to outsiders, he was completely sure that he could shatter it with one punch.

After the two entered the cave, they appeared in a long and narrow tunnel, the width and height of the tunnel were similar to the stone gate at the mountain wall, and the passage was composed of hard stone walls all around, and the whole body was pitch black, but Du Fan and Guo Huaifu were cultivators, and they both had divine thoughts, so they didn't have to worry about hitting the stone wall with their faces.

After walking a cup of tea in the passage, the two of them still did not come to the end, of course, there was no branch where they had just passed, that is, at this time, for them, there was only one way forward.

The place where they were at the moment was recorded in the treasure map, so Du Fan didn't worry too much.

Du Fan found that the narrow passage they had walked was slightly downward, and although the slope was not obvious, they had already walked at least a few hundred zhang forward, and they should be at the bottom of the lake at this time.

After the end of the meal, there seemed to be a point of light in front of them.

"Senior, that's the core area of the cave. Guo Huaifu said.

Du Fan didn't have an interface, and continued to walk as he walked.

As they continued to move forward, the point of light in front of them became bigger and bigger, and finally after half an hour, the point of light turned into a stone door with a milky white light, and it was erected in front of Du Fan and the others.

"Is this a ban or a magic circle?" Du Fan glanced at Guo Huaifu and asked lightly.
