In the cave full of dark aura, on top of a dark altar, there are dark runes with different spirits. A long sword was inserted in the center, and a layer of fine patterns had emerged on the sword surface, which originally looked a little ordinary.

The pattern is four, one side of two complex long patterns completely cover the sword blade outside the sword body, although these patterns are all black, but they exude a kind of soul-attracting atmosphere, like a whirlpool, involuntarily, attracting people's hearts to it.

The hilt of the sword is straight, black ink like jade, and the texture is concave and convex. The sword lattice and the hilt of the sword body are integrated, and on the three-inch sword body above the sword lattice, two ancient seal characters suddenly appeared, "Dark Annihilation", if Mu Lin saw it, he would definitely be very surprised.

However, Mu Lin couldn't see it at this time, because his eyes had already been closed, and the immortal consciousness had already been suppressed here, and he didn't have the extra energy to perceive the things around him.

Because the tadpole-like dark spell on the magic robe around him at this time has left his body, and he no longer looks like a fairy clothes, and the magic trick has become somewhat similar to the square dark runes on the altar, and it has a dark aura that he didn't have before.

However, not all the runes on the altar have an effect on the spell, and the eastern part outside has the greatest influence on the spell. The formula became somewhat similar to that part of the formula, and then out of thin air, a line of Dao rules appeared, connecting all the formulas. There are many threads of rules, and in the end they are connected and become clothes and shoes again.

This time, however, the Magic Clothes are becoming a little translucent, from being completely black before.

At this moment, a purple book seemed to "jump out" from the ink snow, and the name of the book that emitted a dazzling purple light had changed. After the original Shadow Ancient Characters, four more words appeared, the Nine Realms True Scripture.

"The Law of Shadows is beginning to appear, the interweaving of light and darkness, the second level of the Nine Realms of Shadows True Scripture. It's like it's real and it's not real, it's everywhere. Shadow, darkness descends, shadow, mastery of darkness. ”

Although Mu Lin had abandoned his distracting thoughts at this time, a purple book also appeared in his soul, and its appearance was the same as that of books in the outside world.

"Is this the Shadow Exercise? Why is it a little different? The name seems to be different?" Just when Mu Lin's brows were furrowed and he couldn't figure out the situation, the purple book automatically opened, and although the artistic conception of the heart method and mantra was similar to the previous Shadow Exercise, the content was completely different.

"It's better to give it a try. Mu Lin followed the new recipe in the book, and typed out the trick in his hand that seemed familiar but completely unfamiliar. One spell after another hit the dark void inside this cave, and instead of dissipating immediately as before, they gathered together very quickly. It turned into an hourglass, and the top half of the hourglass had black grains. In the lower part of the hourglass, there are transparent grains with no color.

"Shadow is the other side of the world, the shadow of darkness, the darkness of shadow. Mu Lin read this exercise and realized something, and countless magic tricks appeared on top of the translucent magic clothes, and one after another were printed on Mu Lin's skin.

Mu Lin felt that these tricks he had played seemed to have appeared on his body after being tempered.

As soon as his eyes opened, although this place was still the same as before, Mu Lin no longer felt that the cave in front of him was so dark, and the things he saw became very clear.

"Is this the Shadow Technique?" Mu Lin took the purple book that floated in the air, and found that the content inside was exactly the same as the one that appeared in his soul, and the previous font was no longer there for some reason.

Looking at the things in his ink snow again, Mu Lin found that the three exercises that he had originally put together had become two.

"Will the exercise books change themselves?" Mu Lin looked at this very special book and had some doubts. Although his absence has not improved much, his swordsmanship has improved, but the swordsmanship book has not changed, but this shadow technique has changed.

"Shadow Nine Realms, is this the full name of the exercises?Second level?How many are there?Nine?Ten?" Mu Lin was not very sure, the hourglass in his hand disappeared suddenly, and the clothes of the magic method instantly melted on the skin.

At this moment, Mu Lin's eyes flashed violently, his body retreated sharply, and his body also lit up, and a layer of shield instantly formed in front of him.

Because at this time, on the altar of darkness, the dark energy seems to be about to be exhausted, and it is all injected into the darkness. Therefore, the altar just now was already extremely unstable, and the dark runes had begun to shake violently, and at the moment when the wood forest retreated, the altar finally erupted, and a black light erupted from the altar, causing a huge impact.

Mu Lin felt that he couldn't control his body, and although he tried his best to control the speed of retreat, he kept retreating sharply. The black air flow was so powerful that he couldn't stop at all.

The sword in Mu Lin's hand plunged into the stone wall next to him, and on the mountain wall, two extremely deep scratches were made, but he still couldn't stop.

Suddenly, Mu Lin heard a sound of wind behind him, his face changed violently, and when he looked back, he had actually arrived at the entrance of the cave he had just come to. And then there is the dark abyss.

If it drops, it won't turn out too well.

As soon as the sword in Mu Lin's hand turned, the resistance received by Mu Lin suddenly rose, and the speed finally slowed down, but at this speed, it was still not safe.

Stomping on the ground under his feet, Mu Lin's body was already tilted and almost clinging to the ground, trying to slow down his speed as much as possible.

"Whew!" There were four long marks on the ground and walls, but when they reached the entrance of the cave, these traces finally disappeared, and Mu Lin's figure stopped dangerously at the entrance of the cave, and almost fell.

"Fortunately!" Mu Lin exhaled and said happily.

But in the next moment, his smile completely disappeared.

Because a more ferocious black aura surged again, Mu Lin's foothold was unstable, his body was blown up directly, and his two legs had reached the cliff outside the cave, but fortunately, the sword and sword were on the stone wall at this time. So Mu Lin hadn't fallen yet, but he was already in danger when he was blown up, so Mu Lin tried to keep his balance as much as possible, and moved his two hands on the sword, trying to stand in the cave again.

However, the surge of dark aura caused the impact on the wood forest too great, and the speed of the wood forest was severely restricted.

"Whew!"

Mu Lin's pupils shrank, and he found that the long sword that pierced into the stone wall had slowly broken away from a part, and he was anxious, Mu Lin wanted to return to the cave as soon as possible, but the impact of the air flow did not weaken in the slightest, so his speed was still like a snail, and it was slow.

"I'll go!"

The long sword suddenly detached, causing the wood forest to stumble, leaving only a wolf knife still on the stone wall, and his body was already beyond the cliff.

"It's a big game. Mu Lin watched as the wolf knife that was left slowly fell off, but there was nothing he could do.

Looking at the endless cliff, there was a trace of fear in his heart.
