On the fourth floor of the Yuanwu Palace, there are many source methods of Xuan Rank placed here.

Although these source methods have advantages and disadvantages, in terms of grade, they have reached the Xuan level, which is obviously enough for the disciples in the sect who have not yet grown up.

Dong Tu Nan went up the stairs and soon reached the location of the fourth floor.

"It is worthy of being the storage place of the Xuanjie Source Method. Dong Tu Nan sighed.

He could clearly find that in this part of the fourth layer, there was an inexplicable source qi permeated, like a dream, as if it was the place where the rich source qi of heaven and earth was born.

"The source gas content in this place can reach this level, presumably because of a large number of Xuan-level source methods. ”

He knew very well that the ordinary source method martial arts, once they reached the Xuan level, meant that they were quite powerful.

And in the position of the fourth layer of this Source Martial Palace, most of the source methods of the Xuanyun Sect over the past hundred years were hidden, and the invisible aura exuded by them could be imagined.

"No matter how much it is, it's the right thing to do first to find a source method about swordsmanship. Thinking so in his heart, Dong Tu Nan had already taken a step, walking back and forth between several stone platforms where the source method was placed.

After reading it several times, the source law cheats on each stone platform are all in full view.

"Xuan-level medium source method, poisonous dragon thousand wind sword. Dong Tu Nan looked at the strange name, and in curiosity, he picked it up.

"The Poisonous Dragon Thousand Winds Sword Technique, when the practitioner performs it, its momentum is like a dragon flying into the sky, fierce and vicious, like a swift wind sweeping the ground, and between one move and one style, it contains a fierce offensive. ”

"Xuanyun Evaluation: The Poison Dragon Thousand Wind Sword Technique is superior to the same source method of the same level, its attack power is strong and the sensitivity is high, but the resistance and stability are weak, and it is not suitable for protracted battles. ”

The cheats booklet was slowly opened, and the first thing was a detailed introduction, which generally introduced the characteristics and advantages of this set of swordsmanship, so that its basic advantages and disadvantages were clear.

Finally, a sentence of commentary is attached, as for the "Xuanyun Evaluation" mentioned above, it should be left by the successive masters of the Xuanyun Sect.

"It's too aggressive, it's too heavy, it's not for me!" Dong Tu Nan shook his head, and then put it back again.

"The Xuan rank is medium, and the anti-mountain heavy sword technique. ”

Another source method secret book was held in his hand.

"The method of resisting the mountain and the heavy sword, the method of the heavy sword. As the name suggests, it is the word 'heavy'. The great sword has no edge, but by virtue of its weight and bluntness, the direction of things is crushed and destroyed. ”

"It seems to be the source method of a heavy weapon, I already have the Mohan Sword, but it is not suitable for me. Dong Tu Nan muttered to himself, and then looked at its comments again.

Xuanyun commented: Heavy sword style, strong and fierce. The great sword has no edge, but it is infinitely powerful. It's just that there are high requirements for the strength of the practitioners, and the agility is too poor, which is suitable for group sweeping, which is not conducive to individual combat. ”

"Sure enough, it's basically the same as I thought. After reading a few pages, Dong Tu Nan lost interest and put it back again.

For him, the least thing about a good set of swordsmanship is that he must not have too prominent weaknesses.

Because of the practice of such swordsmanship, you will encounter all kinds of problems in battle, and once the opponent catches a prominent weakness, you will fall into danger at that time.

And the two source methods he saw just now, the former mainly lacks defensiveness, and the latter is domineering and fierce, but it greatly reduces the sensitivity of the sword technique.

Generally speaking, in terms of their respective fields, these two sets both belong to the middle level of the Xuan Rank, and it cannot be said that they are not good swordsmanship.

But both of them have a prominent bias characteristic, strong attack but no defense, less strong and less strong, which also makes the whole set of swordsmanship not so balanced in attack and defense.

"Since I want to choose a sword technique, the Xuan level can at least allow me to use it before the Tianyuan Realm. So, first of all, it needs to be suitable for the attributes of the Mohan Sword, and secondly, it is both offensive and defensive, and it is best to have some other characteristics. ”

Dong Tu Nan thought in his mind and listed some requirements before the other side began to search.

For that part of the swordsmanship that is completely untouched, I directly chose not to look at it.

Because every time he looked at a source method, he also needed to spend energy, not to mention such a mystical level, which was a test of his mental firmness.

But after looking for three circles inside and three circles outside, the entire area of the fourth layer was almost searched by him, and he still couldn't find anything that matched his heart.

These sword-type source methods are either very different in attack and defense, or their attributes are contrary to the Mohan Sword, and there are always such strange aspects that are not suitable.

"That's it, just pick one and use it first. Seeing that there was really nothing to distinguish, Dong Tu Nan only sighed, that is, he was going to take a source method in his hand.

"Huh?" Just as he stretched out his hand and put his five fingers on a source law secret book, the corner of his eye seemed to suddenly flash for a while, as if something emitted a faint fluctuation of source power.

"What's that?" he turned his head suspiciously, scanning around a stone platform, finally fixing his gaze on a corner at the end of the aisle.

Da-da-da-da.

The sound of long footsteps reverberated through the stone corridors, making it seem empty and silent.

Somehow, Dong Tu Nan always felt a sense of foreboding, as if he was approaching danger step by step, and a heart immediately hung over his chest.

"It can't be some monster...... "In a panic, Dong Tu Nan was already very close to the end, and continued to poke forward.

Sou!

Before he could react, in the corner in front of him, a black glare suddenly burst out, and it didn't take him even a blink of an eye to fall directly into Dong Tunan's head.

The whole process was extremely fast, and there was no time for Dong Tu Nan to react.

Until everything had happened, he was still in that very confused state, and even his gaze was dull and gloomy.

Buzzing~

I only felt a vibration in my head, and then a sharp tingling sensation spread.

"Uh...... What the hell is this...... The situation?!" Dong Tu Nan held his head directly with both hands, and his body was half squatting on the ground, trying his best to control his pain.

But even so, the intense pain made him can't help but scream, a low roar, like a dying lone wolf letting out a grumbling wail, quite terrifying.

After a long time, this persistent pain gradually disappeared.

"Ouch......"

Finally, the pain in his head disappeared, and Dong Tu Nan was about to stand up in a half-squatting position, but his center of gravity was unstable, and the whole person leaned back directly.

Boom!

The back of his head fell heavily, and there was a clattering sound with the wooden floor.

He held the stone platform with both hands, swayed and got up, only to feel that the melon seeds in his brain were also buzzing, as if there were millions of bees flapping their wings in his mind, and it was difficult to slow down for a while.

"What the hell is going on?" Following the dissipation of this pain, Dong Tu Nan suddenly realized that at this time, there seemed to be several inexplicable energies accumulated in his mind.

"That black glare just now!"

He began to manipulate his consciousness to probe in his mind. It is precisely this kind of investigation that makes Dong Tunan's mood more and more dignified at the moment.

Because the situation in my mind is so complicated!

It's just horrible!

Starting from the ruins of the thief "Palace Nineteen", the Origin Mind Method "Ten Thousand Paths and Thousand Sources Record" obtained entered his mind for no reason, and at this moment it is still suspended in the center.

And then when I was still in Thousand Snow City before, the mysterious stone seal I got at the auction, it only reacted once, and it was completely dimmed.

Until now, that stone seal is still stored in his spatial ring.

After that, it was the election of the Xuanyun Sect, when he was in the Yunze Treasure Land, and there was a riot on the edge of the Burial Demon Mountain Range outside, so he was forced to stop.

However, at that time, he didn't choose to leave immediately, but wanted to further explore the secrets of Yunze Treasure Land, so he inadvertently triggered something unknown. An inexplicable stream of light hit his head, and he immediately passed out.

"Except for the paper symbol that the sloppy old man said, this is the fourth time, but the paper charm belongs to the Lord, so don't worry. It's just that now in my mind, four streams of light have accumulated, and the worst thing is that I don't even know what they are!"

"Oh my God, my dignified young man in his prime, shouldn't he die in the end of his head bursting?" Dong Tu Nan grumbled in fear in his heart.

Thinking of this, his face could no longer calm down, and a worried look immediately appeared.

Four completely different energies converge in such a narrow space without exclusivity.

Among them, the golden light of the "Ten Thousand Thousand Sources Record" occupies the largest space, almost the entire central space, while the other two energies are hovering around it, as if satellites are circulating, very harmonious and balanced.

Now, another black glare is squeezing in, and the magic is that it not only does not break the original equilibrium, but is slowly blending into it.

This really shocked Dong Tunan.

"What is that?" As soon as the thought moved, Dong Tu Nan manipulated his consciousness to probe into the black stream of dazzling light.

Shout!

With a loud sound, the light swirled around in his mind, and then suddenly burst out, turning into small black droplets, suspended in various places in his mind.

呲呲呲......

The droplets trembled, and finally they formed clear words, densely arranged in a large area.

"Paper and ink swordsmanship. ”

A small piece of floating characters has gathered into four big characters as black as ink at this time, and it is faintly covered with a thin layer of light, which is very mysterious.

"Paper and ink, what kind of strange swordsmanship is this?" Dong Tu Nan just felt strange, that is, when he saw his entire upper body, he suddenly felt a sense of numbness.

Immediately, an inexplicable stream of ink bloomed......
