Lin Yu was slightly stunned, turned around and looked at Bairen Tu, only to see that Bairen Tu was frowning at this time and carefully staring at a piece of rubble on the ground that had been overturned due to external forces, with a puzzled look in his eyes.

"What's wrong, Big Brother Niu?"

Lin Yu asked a little uncertainly.

Bairen Tu didn't speak, then walked to the gravel and squatted down, stretched out his hand and touched the gravel, and said in a deep voice, "This gravel was originally paved on the ground, but the bottom layer of the stone, half of it was soaked in water vapor, and there was such a lush moss, obviously there was moist air circulation underground, in other words, there was a very likely secret passage under this stone slab!"

"There is a secret passage?!"

Lin Yu was slightly stunned, obviously a little surprised, and then stepped on the ground with his feet hard, but because the stones on the ground were very hard, he didn't hear the slightest abnormality when he stepped down.

"When I lived in the mountains with my master, I also made this kind of darkening, so I could see at a glance the strangeness of this stone!"

Hundred people said in a deep voice.

In fact, including now, many temples on the mountain, Taoist temples, many of them have built secret grids or secret roads, large or small, some are for storing things, and some are for emergency escape, and the hundred people who grew up on the mountain with the master since childhood are naturally very familiar with this.

After saying that, Bairen Tu raised his legs and walked out, and after a while, he came back with a branch the thickness of a small arm in his hand, handed it to Lin Yu, and said, "Sir, you just use it to smash the ground hard!"

As he spoke, he leaned down sharply and fell to the ground with his ears on the side.

Lin Yu immediately understood his intentions, and without saying a word, he smashed the wooden stick in his hand on the stone floor.

Bairen Tu waved his hand at Lin Yu while listening, and Lin Yu moved the position of the wooden stick from time to time according to the meaning of Bairen Tu.

"Wait!"

Bairen Tu suddenly raised his hand and motioned for Lin Yu to continue tapping a few times in the place just now.

Lin Yu added strength, and knocked the stone slab with a wooden stick again, and Bairen Tu heard a muffled sound of "dong dong" below, so he got up and said to Lin Yu, "This is it!"

Immediately after that, Bairentu directly reached out and picked at the mud gap between the two floors, and then opened his feet, tightened his horse steps, and suddenly exerted all his strength to lift the stone slab up.

Rao is a master of Bairen Tu, when he opened this stone slab, he clenched his teeth crown, his face was red, and the green tendons on his forehead burst out, showing ten strength, which shows how heavy this stone slab is.

Seeing that Hundred People Tu couldn't lift this heavy stone with his own strength, Lin Yu's face suddenly changed, and he was surprised, and hurriedly rushed up with an arrow step, helping Hundred People Tu to overturn this heavy stone to the ground together.

"Bang!"

With a loud bang, the stone slammed to the ground, Lin Yu and Bairen Tu glanced at each other, obviously extremely surprised, I don't know if it was the weight of the stone itself or the reason for any other strength, it was so difficult to lift this heavy stone slab!

No wonder there is no need to make any mechanism under this stone, because looking at the world, there are probably only ordinary people who can lift this huge stone with the power of one person!

I saw that after the boulder was opened, a black dark passage was revealed below, the caliber was very small, that is, only one person could pass through, and the dark grid blew a cool breeze, with moisture, and the stone walls on both sides of the dark passage were also very slippery, with heavy water vapor.

"Let's go, go down and have a look!"

Seeing this, Lin Yu was immediately curious, and he was not worried about whether there was any danger, so he directly proposed to go down and have a look, probably because there was a master like Bairen Tu with him, so he was also extremely bold.

Bairen Tu did not refuse, and said to Lin Yu, "I'll go down first, and you will come later!"

Because he was afraid of any danger below, he proposed that he go down first, and as soon as the voice fell, he jumped down first.

Because this secret passage is very deep and dark, judging from the dull sound of the hundred people slaughtering the ground, this secret passage must be extremely deep.

"Sir, you can come down, this secret passage is very deep, you should be careful!"

Hundred people slaughtered below and shouted up.

Lin Yu responded, then also shrank his arm and jumped down flexibly.

Sure enough, as Bairen Tu said, this secret passage is very deep, several stories high, if ordinary people who don't know just jump down like this, they will definitely fall to their deaths.

"Boom!"

After Lin Yu jumped under the dark grid, he felt a slight shock on the surface of his feet, and saw the black rumbling around him, and was about to reach out to touch the wall, when he found that Bairen Tu had reached out and pushed open a stone door in front of him.

Suddenly, a bright light came in, and Lin Yu hurriedly looked up, only to see that the stone gate turned out to be a cave about several meters high!

Because this cave is not too deep, so Lin Yu and Bairen Tu can clearly see the scene outside the cave at this time, only to see that the outside of the cave is a dense bamboo forest, through the bamboo forest, you can see more than a dozen bamboo houses clustered in the forest, there is a vegetable field surrounded by a bamboo fence in the far away of the bamboo house, but because of the season, there is no vegetable in the vegetable field at this time, and there is a stream flowing through the bamboo forest, which is very quiet, and there is a feeling of a paradise.

Lin Yu and Bairen Tu were all a little surprised, obviously they didn't expect that there would be such a place hidden on the mountain behind them.

"Sir, it seems you guessed right, this is where they live!"

Hundred people said in a deep voice.

"Let's go!"

Lin Yu was excited, and rushed to the bamboo house with some impatience, expecting to find something.

But when they rushed into the bamboo house, they found that there were indeed traces of people living in the bamboo house, but it seemed that it had been searched inside, and it looked very dirty.

"Sir, someone has been here!"

After searching a few bamboo houses, Bairen Tu only found some magic tools and other things used by Taoist priests, and there was no big gain.

"Either outsiders have been here, or they have come back on their own!"

Lin Yu said in a deep voice, guessing in his heart that it was definitely the latter, that the big devil left the Fire Dao and a few disciples after escaping, in order to avoid being discovered here, he would definitely come back again and take all the useful things with him.

"This house is the largest, and it should be the place where the Fire Dao people live!"

Bairen Tu pointed to the largest bamboo houses in the middle and walked in with Lin Yu.

I saw that there was a half-human-high Dan furnace in the hall of this bamboo house, and the lid of the furnace had been lifted, revealing some black and red filth inside, and I couldn't tell what it was, but there was a pungent smell.

Lin Yu and Bairen Tu Qiqi covered their mouths with their sleeves.

"Big brother step, be careful!"

Lin Yu whispered a word to the hundred people to slaughter, feeling that this place where the Fire Dao people lived was really a bit evil.

The two of them walked around these bamboo houses, and found that these bamboo houses had been rummaged through from the hall to the bedroom, and there were almost nothing of value, but just as they turned to leave, Lin Yu was suddenly attracted by a broken wooden board by the window.

Lin Yu walked over quickly, carefully picked up the wooden planks piece by piece, put them on the table and put them together neatly, only to see that there was a very strangely shaped nine-headed spike plant carved on the wooden board.

Lin Yu squinted, sneered, and said, "It turns out that this Fire Dao person still has such a sweet dream!"

Bairen Tu was slightly surprised when he heard Lin Yu's words, walked over and glanced at the wooden board in Lin Yu's hand, and said with some doubts, "Sir, this is?"

"Brother Niu, have you heard of Jiu Suihe?"

Lin Yu smiled and said.

"Nine Suihe?"

Bairen Tu shook his head and said truthfully, "I really haven't heard of this. ”

"This Nine Suihe has been mentioned in some of the past dynasties!"

Lin Yu looked at the pattern on the wooden board and said in a deep voice, "Legend has it that there was once a Danque that brought these nine ears of grass, fell to the ground, and was picked up by Emperor Yan and planted in the field, and anyone who ate these nine ears of grass can live forever!"

"So is there really such a thing as Nine Spikes in this world?"

Bairen Tu frowned and wondered.

"It's just the wishful thinking of this old way!"

Lin Yu snorted coldly, "Throughout the ages, who has ever had this immortality! Besides, thinking of an evil person like him, even if he is immortal, what is the point, it is just spurned by the world!"

Bairen Tu nodded, and said in a deep voice: "I suspect that he killed people, is it also to achieve his goal of immortality?"

"Highly likely!"

Lin Yu nodded, thinking deeply, although they didn't get anything substantial from this trip, but being able to figure out the purpose of this old way can be regarded as a kind of gain, Lin Yu even came up with a way to lure this old way to the bait.

"Who?!"

At this time, Bairen Tu suddenly screamed, and his body jumped out of the window suddenly, and quickly rushed towards the bamboo forest.
