At this time, the river under the Big Buddha is roaring, looking at the still wet Big Buddha's knees and the water marks along the line, it should be not long ago, the river here has risen to this position.

Looking at this scene, Yu Nan's eyes flashed and he said to himself:

"Flooding the knees of the Buddha and burning the Lingyun Cave, it seems that not long after the battle between Duan Shuai and King Nie Ren ended, the children of the two were also taken away by Xiongba."

Observed the surroundings, at this time there was no trace around the Leshan Giant Buddha, he jumped to the Buddha's knees, to the left side of the mountain wall to take a look, on the mountain wall a two-zhang cave mouth is scorched black, the cave wall is full of beasts scratched out of the half-foot deep claw marks.

If you sniff carefully, there is still the smell of burning in the air, needless to say, this is all the traces left by the fire qilin rushing out of the cave before.

Yu Nan did not enter the Lingyun Cave directly, he tied a rope to the boulder next to him, put it on his body, and jumped into the river.

The reason why I want to dive into the river is because there is a knife on the stone wall under the Buddha, the most powerful knife in the Fengyun world, the ancestor of the Nie family used Bai Lu, one of the four sacred stones in the Fengyun world, to create it.

Since he arrived in front of Lingyun Cave, if he didn't take this knife, would he still keep it for Nie Feng? Nie Feng has nothing to do with him, let alone have a relationship, he cares, as for the few people who will be enemies of Nie Feng, they are very powerful, and Nie Feng without the Snow Drinking Knife is estimated to be difficult to match, but he doesn't care about this matter, these evil people happen to be Yu Nan's target, if he wants to find the benefits of this world, he may become the enemy of most people.

Jumping into the water and groping for a while, Yu Nan pulled out a snow-white long knife from the mountain wall, even if this knife was not urged by internal force, the cold air kept coming out of the water in the water to turn the surrounding water into ice crystals, if it weren't for the turbulent water around it, it was estimated that it could freeze the water in Fang Yuanzhang.

Putting away the snow drinking knife, Yu Nan pulled the rope and jumped directly out of the water and jumped onto the knees of the Buddha, and dried his clothes, he looked at the dark entrance of the Lingyun Cave and whispered to himself:

"The treasure of Lingyun Cave, the dragon vein doesn't know what it is, the invincible Xuanwu True Skill can be used for learning, and the six tips of Aohan can also be learned, what is really useful to me should be eating the blood Bodhi that can increase internal force and the unicorn blood with unknown effects;

It's a pity that only two blood Bodhi are effective, and if you eat more, you will be resistant, and at most you will be a healing medicine, but if you eat two, I should be able to penetrate the bridge between heaven and earth to achieve innate results, and let me live to be two or three hundred years old.

As for the Qilin Blood, the Fire Qilin must be killed, God knows how powerful this guy is, and I have to be extremely careful after entering the cave, so that I can not encounter it, and it is best not to encounter it before breaking through. ”

Yu Nan has already broken through the second vein of Ren Du after eating the secret of Guiyuan in the world of the Immortal Crane Divine Needle, according to the first vein of martial cultivation, he is already the peak master of the day after tomorrow, and he only needs to open the channel on the top of his head, so that the Heavenly Spirit Baihui can connect with the acupoint of the Meixin Yin Hall, and he can achieve innate cultivation.

Compared to the masters of this world, he didn't know how strong he was, but he calculated that his martial arts pure combat power was more than a star and a half worse than his own evolution;

Comparing his simple speed with the volley void and the Five Elements Lost Steps, only with the internal force urging, his speed is at most ten times that of a normal person, which is just weird and unpredictable, but once he uses his own strength to urge the Five Elements Lost Steps, more than a dozen of his phantoms will appear at the same time within a radius of ten zhang, just to say that the skills of martial arts are strong, and the internal force has the ability to prolong life and improve physical fitness, which is the reason why Yu Nan chose penance.

When he arrived in the world of wind and clouds, he didn't dare to be sloppy and careless, he couldn't shoot Lao Ma's comics and novels in movies and TV series, you must know that in a few years, Nie Feng's speed will reach twice the speed of sound, which is nearly twice as fast as Yu Nanke, and at such a speed, he can't guarantee that he can take a few hits with rough skin and thick flesh;

As for technological weapons, it is enough to lock and fire at such a speed, at most they can only use the pre-judgment technology to assist, as long as they hit, with the power of the laser beam or electromagnetic railgun, Yu Nan can guarantee that even the emperor will not be able to withstand it.

With such a weapon, coupled with the yellow-shirted battle suit that could become bigger and smaller at a critical moment, Yu Nan still planned to enter the Lingyun Cave knowing that he was not the opponent of the Fire Qilin with his martial arts ability alone.

However, he also knew that the Lingyun Cave was thousands of miles deep, and the passages inside were as dense as spider webs, so he had been researching how to scan the maze all year long, especially when there was no satellite system here, and even if there were, it would be difficult to penetrate the mountains;

Using his various technologies, he has created a gravity-defying floating detector, each the size of a fist and numbering thousands, which is controlled by a host system, and as soon as he enters the cave, he begins to explore the cave continuously, and the miniature signal adapter aggregates the scanned maps to form a three-dimensional map, so that he can safely enter the cave to find what he is looking for.

With preparation, it is not easy to be unlucky, Yu Nan firmly believes this, he strode to the entrance of the cave, pressed his hand on his waist, and small round balls the size of a fist flew towards the depths of the dark cave.

These detectors flew into the cave for only half a minute before sending back the first set of signals, and after the host scanned and amplified them, a red long sword was found stuck in the ground at the inclined hole of only a thousand meters into the cave.

Seeing the long sword from the scanned image, Yu Nan said secretly:

"The Fire Lin Sword, a sword sharper than the Hero Sword, is inlaid with a piece of Fire Qilin's scale armor, which can make the sword wielder go into the evil path, I don't know if it's true."

Yu Nan said as he entered the cave, and when he arrived in the cave, he changed into a yellow shirt, in the dark hole, the shimmer system and the observation system made him walk as if in the daytime, and after a while he had already walked to the side of the Huolin Sword, and at this time, the detector group had flown out more than ten miles away and continued to disperse.

Huolin Sword, to be honest, Yu Nan is not interested, because he is not very interested in practicing swords, and there are a lot of swordsmanship in the Guiyuan Secret Book, but he only understands the essentials and tricks of using swordsmanship, and never studies the tricks, all he wants to master is how to crack it.

Not being interested doesn't mean that Yu Nan won't take it, the Huolin Sword is also a good sword, not to mention that if he wants to study whether the Huoqi blood will help him, it is also a direction to study the Huolin Sword first.

When he arrived at the Huolin Sword, Yu Nan directly grabbed the hilt of the sword and pulled it out, and the Huolin Sword, which was faintly emitting red light in the dark cave, trembled in his palm, and suddenly a layer of pitch-black aura appeared from Yu Nan's body and blasted into the Huolin Sword along his hand.
