"Black Haze!"

In Lin Feng's hand, the Heavenly Saint Soldier Black Yan danced.

Every time the knife is swung, it will emit a strong black haze, mixed with coldness and fear, unconsciously changing the environment, unconsciously emitting, the fine black spars on the black knife are scattered, and the black haze is getting thicker and thicker.

"Single, group battles, all are used." The black in Lin Feng's hand waved rapidly.

"The effect of the black haze is good, destroying the enemy's defenses, it will infiltrate the body unconsciously, and the effect on the enemy who is not strong enough will have an immediate effect. As the battle lasts, the black haze effect will get better and better, even obscuring sight and breath. ”

Drink!

Lin Feng's dark aura erupted violently.

The terrifying rotating centrifugal force took itself as the origin, and the surrounding earth shook violently, like a dark dragon infiltrating the ground under its feet, straight in all directions, the earth undulated and changed, the dark aura tornado and remnant clouds instantly unfolded, and the huge whirlpool blasted from the outermost to the sky.

Huh! Huh! Huh!

The strong centrifugal force will crush the entire space.

"Intermediate Aoyi, Eight Hundred Nightmare Ghost Swirl." Lin Feng kept swinging the knife in his hand, and even the black haze was also violently moving, the two whirlpools, one inside and one outside, formed an incomparable tacit understanding, and the auxiliary attack effect of the black haze whirlpools was good.

The earth shook continuously, and the black Yan in Lin Feng's hand trembled violently.

"The first form of the seven limits, breaking the sea!" Lin Feng slashed violently, declaring absolute power.

However, there is always a lack of true essence.

…

"Seven limits, it's really difficult." Lin Feng closed the knife.

Seven days of retreat, six of which were spent pondering the knife technique, so far the first type of sea breaking has barely mastered a trace of the prototype, and this is still the situation of the 'teacher', the figure of the primordial heavenly demon in his mind, and the feeling of practicing the knife on weekdays is extremely clear.

The battle with the enemy shows the true meaning of the sea-breaking knife.

"It's not that I don't have enough understanding, it's mainly ... The realm of sword art is not enough. Lin Feng was well aware of his shortcomings. It's as if the eyes are fast enough to see the enemy's moves, but the body doesn't listen to the command, and the sword technique realm is not enough, making it extremely difficult for him to cultivate the Seven Limits.

Knife technique, the tenth realm is complete.

In the tenth realm of the Blood Mist Forest, after encountering the Blood Sword Method, the cultivation stagnated.

"The first form of the Seven Limits 'Breaking the Sea', if you want to fully comprehend, you probably need to step into the eleventh realm." Lin Feng had a very clear understanding of the Seven Limits, after all, there was a ready-made teacher in his mind, and the cultivation of the Primordial Heavenly Demon Xuan's sword technique was quite terrifying.

Harvest. Not for nothing.

In just six days, the realm of sword art has been upgraded from the tenth realm of small success to great completion.

Every time you break through the sea, it is the most direct understanding of the essence and true meaning of the knife. Lin Feng was not in a hurry, although his sword technique could not be improved for the time being, but the comprehension of the mystery of darkness and the strength of the Heavenly Saint Soldier Heiyan had made his strength take a big step forward.

"The power of the Heavenly Saint Soldier Black Yan and the Mystery of Darkness can complement each other."

"The same is true of the second type of power, 'Dragon'."

"It's just that the dragon is different from the black haze. The dragon is an absolute enhancement and explosion of strength, which is completely inconsistent with the Eight Hundred Nightmare Ghost Spiral, but it is very compatible with another intermediate arcane meaning, but it is ......" Lin Feng hesitated. It was immediately vetoed.

It is difficult to comprehend the intermediate mysteries.

Combining the power of the Intermediate Arcane Meaning with the Celestial Saint Soldier's power is only a little less difficult than the Fusion of Sword Techniques, and it is also not easy.

"Vortex Aoyi!"

"Find a vortex that is similar to the Eight Hundred Nightmare Ghost Spiral."

Lin Feng quickly made a decision.

But the mystery of the whirlpool. I can always comprehend it very easily, and the intermediate meaning of the Eight Hundred Nightmare Ghost Spiral, although it is not the first time to understand it. But it only took three casts to master the trick, and it took less than half an hour to cast it perfectly, even if it was fused with the power of the Heavenly Saint Soldier 'Black Haze', it only took a day.

Vortex body, strong terror.

"Cultivation, support, extremely powerful bloodline, and ......"

"Defense."

※※※

Temple of Blood Mist, Exchange Hall.

Different from the hall where the acquisition task was issued, the exchange hall was obviously much larger and more spacious, after all, it was one of the facades of the Blood Building, the blood killing point, and the circulation of Nemo coins were all here, and the three Seven Blood Killers and one Eight Blood Killer who were responsible for managing the exchange hall were the three Seven Blood Killers who had retreated.

Three supervisors, one chief manager.

Being in the Blood Building, Lin Feng knew everything about the Blood Mist Land.

"Hello, Director He." Lin Feng said respectfully.

The man with pale temples in front of him was one of the three supervisors, Director He Huhe.

"Blood Tower 30." He Hu's spicy eyes glanced at Lin Feng's battle armor, and his eyes narrowed: "You are the newcomer Lin Feng?" ”

"The director, good eyesight." Lin Feng smiled, and the instant inference of clues was indeed worthy of being a seasoned seven-blood killer, and he went straight to the point: "I wonder if the director can help select the classics about Aoyi?" ”

The classics of Austria and Italy are varied and quite complicated.

Although the exchange office is clearly listed, it is difficult to deduce from just a few words, such as the Eight Hundred Nightmare Ghost Whirlpool is quite clear, but many of the mystical meanings are actually only part of it. Moreover, there are too many classics, and there are more than 10,000 books of various mystical classics alone, many of which are duplicates.

For example, the Eight Hundred Nightmare Ghost Spiral can depict the use of mysteries from shallow to deep, or it can be directly told like a knife, and even some are just a description of words.

The supervisor who manages the exchange hall all the year round is different, and he has a lot of expertise, just like the library on the earth, which book is in which location, and the experienced librarian can know which book is in which place.

"Yes." He Hu was quite kind to Lin Feng: "What type do you want?" ”

Lin Feng said directly: "Light system, dark system, and thunder system, all the mysteries mixed with the vortex type, the higher the better. ”

"Vortex type?" He Hu sighed softly, glanced at Lin Feng thoughtfully, didn't pay too much attention, and bowed his head slightly, "Wait a minute." ”

Immediately, the pot turned around and entered the side door, selecting the matching classics.

It's normal to have a request.

Some martial artists are good at attacking, some are good at defense, and some are good at formations, but when it comes to the vortex type, it's still a little peculiar. However, for the director who has managed the exchange office for decades, it is only a gesture.

Soon—

"It's all here." He Hu placed five books on the table.

"Four intermediate Austrians and one advanced Austria."

He Hu looked at Lin Feng: "However, this high-level Aoyi "Vortex Change" is not described in detail, and the price is expensive, whether you need to weigh it yourself." After a pause, He Hu added: "The highest grade in the exchange office is the high-grade Arcane, except for a few books, most of the high-grade Arcane are very general and not described in detail. ”

"You're lucky, you just happen to have this vortex type of advanced arcane of light."

"Vortex".

Lin Feng's eyes lit up.

Then look at the other four intermediate mysteries, for themselves, these are all treasures that can directly improve their combat power!

Because, it can be mastered very quickly.
