Fifty meters down, the first characteristic polymer composite material made of climbing rope is exhausted, but Lin Xiao carries not only one, this kind of rope is not thick, not heavy, fifty meters of rope total weight is only 500 grams, Lin Xiao carried six! Now there are five more, enough to support Lin Xiao to slide 300 meters away, it is estimated that the crack will not be so deep, right?

However, Lin Xiao was still disappointed, when the last rope was used up, the crack had bottomed out, but under the strong fluorescent light, Lin Xiao judged that from his current position to the bottom of the crack, there was at least five meters in height!

If you change to flat ground, the height is five meters. Lin Xiao didn't care at all, but this place was deep in the crack, and the ghost knew if it was smooth below, jumping down, in case he broke his foot or even broke his leg, it would be a bad breath, and the ground should not be called.

However, this is not difficult for Lin Xiao - at this time, it is time for the strong crossbow that Lin Xiao has built himself to play a role!

On the way down, although the crack is getting narrower and narrower, but when it comes to Lin Xiao's current position, it has become wider again, the whole crack is like an X, and the further down the stone wall, the higher the hardness of the stone wall, at the beginning, if Lin Xiao can still knock the safety nail into the stone wall with the trekking hammer in his hand, by the last fifty meters, Lin Xiao has rounded his arm and failed to chisel a nail into it - and if he wants to open the distance, he can't open his arm with a strong crossbow!

But now it's different, Lin Xiao, who is hanging on the rope, can use a strong crossbow this time!

The strong crossbow designed and built by Lin Xiao himself is not only twice as tense as the military crossbow, but the arrow cluster used is also made of special alloys - not from any material research institute, but an alloy formula that Lin Xiao accidentally discovered when he was tinkering with this strong crossbow during a holiday - it is better to say that it was cast!

Because once this thing is formed, even the grinding wheel of the emery can't grind! This is the result of Lin Xiao's own experiment, using the high-end goods that can only be used by the precision manufacturing obtained by his father Lin Mosheng through the relationship, and Lin Xiao's purpose is nothing else, that is, the block that was poured for the first time (let's put it this way) is really cold, and he wants to shape that thing, but the grinding wheel is used up by nearly a quarter, but the lump has not even changed a burr, if you want to return to the furnace, the temperature of argon arc welding is used to a certain extent, Lin Xiao can't stand it, and the lump has not changed much!

This is terrible, Lin Xiao knew that he had inadvertently discovered a new type of alloy - but the temperature before pouring did not reach that high!

So when Lin Xiao built the arrow cluster again, he was sneaky, and he didn't dare to let others know, but now there is nothing to hide, with the sharpness of the arrow cluster cast in this alloy, subduing the stone wall here, just four words: no problem!

What Lin Xiao had to do was to use the arrow as a rock climbing hand, chisel out a position for himself to start and pedal, and then slowly climb down this last distance.

When it was only two meters away from the ground, the scene that frightened Lin Xiao came into view: under the illumination of the searchlight, Lin Xiao saw the white bones of dozens of people! Why dozens of people, nonsense, there are so many skulls! The most important thing is that these white bones are sitting neatly against the wall, and there are still wisps of residual clothes on their bodies, when Lin Xiao's searchlight swept by, he suddenly saw so many skeletons grinning at you, so he asked if you were afraid!

In the middle of the many corpses, there is a dark and secluded passage, Lin Xiao, who has calmed down at this time, is not afraid, as long as he sees such a neat human corpse, it means that this is not a Jedi! With a passage, there must be a place to walk, those who die here will not all come down from the cracks, right? Lin Xiao did not see any traces of man-made excavation on the stone wall above!

Now there is a strong curiosity about the unknown passage and occupies the absolute upper hand!

There were some unburned torches beside the passage, and Lin Xiao simply lit them - it's better than using a searchlight to drain the power of the high-energy battery, right?

I walked a short distance along the passage, estimated to be thirty or forty meters, which was a turn, then another turn, and another turn...... Even though Lin Xiao is skilled in martial arts and has a strong sense of direction, after dozens of turns, he completely lost his direction!

Just when Lin Xiao was almost numbed by the turn, the end of the passage arrived—it was a tall stone gate.

This stone door was double-opened, not closed, leaving a gap that only allowed one person to pass through, Lin Xiao muttered: "I hate cracks!" and then went into it without hesitation, and then it was a whirlwind of the world, and I didn't know anything.

I don't know how long it took, Lin Xiao was woken up by hunger. When he opened his eyes, it was still dark, but according to the feeling in his stomach, Lin Xiao knew that it would be at least twelve hours! The torch in his hand had long since disappeared, only the searchlight on his head was still there, and the huge backpack he was carrying on his back was still there.

Turning on the searchlight, Lin Xiao looked around, this was still a huge stone room, but what about the gate that had just come in?

Lin Xiao was stunned.

Because his family knows his own affairs, if there is a cliff behind the gate where he enters, then Lin Xiao's leg will definitely be broken in a while! And the internal organs of the body will also be injured - Lin Xiao is also a person who has practiced martial arts to the peak of dark energy, and his control over his own qi and blood is very high, and he can't say that he can be subtle, but he can control it as long as he is awake. Now, Lin Xiao didn't feel that something was wrong at all. Well, it's not right, it's still a little abnormal, but it's not that the qi and blood are weak, but it's more active!

And there is another important point, after Lin Xiao entered the peak of dark energy, his eyesight has greatly improved, I dare not say that it is stronger than the pilot, but it is not bad at all, but under this kind of vision, Lin Xiao did not see any marks such as gates on the surrounding caves!

It's scary to think about!

After Lin Xiao understood his situation, his first thought was, "Did you cross by yourself?" However, there is no way to prove this thing now! The second thought is: "You must first find a way out of the cave or the stone chamber, otherwise you will starve to death in this ghost place sooner or later with only the food and drinking water you carry!"

Just when Lin Xiao was looking for a way out and thinking wildly, an old, distant, and hoarse voice sounded in his ears: "Xiaoyou, are you looking for a way?"

Suddenly, a voice sounded in your ears, and it seemed to be an old man's voice, if it was an ordinary person, it was estimated that it would be able to explode at that time, but Lin Xiao was born in martial arts, strong blood, and courage, and there was also the conjecture of "crossing", so after hearing the human voice, not only was he not frightened, but he also did not show a surprised expression, as if someone was talking and greeting as it should be!

"Listen to the voice, you are an old man, boy, here is polite. I don't know where the old man is, so it's convenient for the kid to come and see him?"

"What a polite little friend. You see, you should be on your right hand side of the rock wall, you walk along the rock wall one hundred and twenty steps, you will come to the end, there is a pull ring on the ground, you pull it up, it will open a stone door, the old man is waiting for you behind the stone gate. ”

"It's not going to be a mountain spirit or something, is it?

"Hehe, little friend, don't be suspicious, this place is the sage dojo of Zhongnan Mountain, where are any mountain spirits and ghosts who dare to be presumptuous here! The old man can't personally camp you, but it's because the old man is just a spiritual sense at this time, but he doesn't have the power to open the door." ”

Lin Xiao listened, but he didn't dare to think about it anymore and didn't dare to run away, but instead walked quickly to the place indicated by the voice, pulled the pull ring, and opened a new door.

A faint white light leaked out from behind the door, it was a very comfortable light, very bright but not dazzling, so that Lin Xiao could easily see that behind the new door was a huge space with neatly arranged wooden frames. And those wooden shelves, Lin Xiaoke is no stranger, almost every Taoist library will be seen - bookshelves! And those hazy bright light comes from the neatly arranged bookshelves! More specifically, the beads inlaid on the top partition of the bookshelf!

However, when the old man's voice sounded again, Lin Xiao found that in the middle of the countless bookshelves, there was a huge low table, and behind the short table was a figure of an equally hazy old man kneeling.

Although Lin Xiao felt from his voice that the owner of the voice had no malicious intent, the so-called defense of people was indispensable, so Lin Xiao was still very nervous, but it did not delay Lin Xiao to give a Taoist salute to that figure, and he still used the Louguan Daoist Hu Lao Taoist to give Lin Xiao a bow.

Although Lin Xiao is familiar with the Taoist collection, he is not a monk in the true sense of the Taoist, and he does not know that the etiquette of a real Taoist priest will reveal his origin and faction through different characteristics, such as the characteristics of the etiquette of Louguan Dao, which is slightly different from that of Longhu Mountain, and the real fellow Daoist can be recognized at a glance. However, this made Lin Xiao make a big profit at this time!

Although the phantom could sense what Lin Xiao was thinking in his heart, it didn't mean that everything Lin Xiao was thinking was discovered by him, and more importantly, he had no way to search for Lin Xiao's memory! But Lin Xiao's etiquette made the phantom very happy!

"Little friend, please get up. I don't know if Xiaoyou is under the door of Louguan Dao?" The phantom question was very direct, but before Lin Xiao could react, he began to tell the specific content like a program.

It is true to say that Lin Xiao took a big advantage, this phantom is none other than one of the disciples that Yin Xi accepted when he cultivated in Zhongnan Mountain, and later because of his poor cultivation qualifications, he automatically asked for the task of guarding the classics and scriptures.

Yin Xiyan passed on the Taishang 5,000 words of the "Tao Te Ching", after Lao Tzu went west, that is, the Taoist heirs who stayed in China, there were many disciples who came to Zhongnan Mountain to follow, and at that time they could enter the mountain to cultivate, there was no one who was not a disciple of a wealthy and noble family, so he also carried a large number of classics of all kinds] and various families, but there were many classics, and there must always be a place to store them, so he opened the mountain and chiseled stones and built this library!
