The first level of absolute concealment - concealment.

As the name suggests, as soon as this technique is performed, the practitioner will immediately and completely hide his whereabouts. Not only is it invisible to the naked eye, but even Lin Feng's Tai Chi Reincarnation Blood Wheel Eye is also unrecognizable!

"Hidden!" Lin Feng repeatedly deduced the true meaning contained in that carved picture in his mind, and after a long time, he spoke softly.

"Buzz ......"

In an instant, a strange energy fluctuation enveloped Lin Feng. Under the cover of this energy fluctuation, Lin Feng's figure in the different space gradually disappeared, just like ice and snow under the scorching sun, and soon disappeared completely, and no trace was seen again.

This kind of scene is very weird, a big living person has completely disappeared like this, which is even more mysterious and terrifying than Lin Feng's "Shenwei" space technique!

"Is this the world-class mastery of the Thunder Mountain Holy Land - the Absolute Concealment Technique?" After a long time, Lin Feng's voice came from the air. "Although you can completely conceal your body, you can't eliminate your own aura, and it's useless to meet a powerful opponent."

"Sure enough, it's just the first level." Lin Feng sighed. He sat down cross-legged again, and set his gaze on the black iron sword again, landing on the second engraving.

His pair of Tai Chi Reincarnation Blood Wheel Eyes activated again, and mysterious rune patterns appeared alternately one after another, which was his natural ability to analyze and dissect the carvings.

This time, it lasted a very long time. Even the Tai Chi Reincarnation Blood Wheel Eye, which is as strong as Lin Feng, feels very tricky about this carving. Lin Feng's face changed, looking elated for a while, and sad for a while, as if he was watching a wonderful movie, constantly changing his mood with the development of the plot.

Three hours later.

"I caught it! I finally caught it! The second realm of absolute concealment - breathing! Suddenly, Lin Feng burst out laughing. He suddenly stood up from the ground and said loudly, "Absolute concealment technique!" Stealth! ”

A mysterious and strange power appeared in an instant, and Lin Feng's figure quickly disappeared.

"The Second Realm - Breathing!" There was another loud roar in the air.

Suddenly, all the aura in this alien space disappeared. Even Lin Feng himself couldn't feel his existence. The feeling was like Lin Feng incarnating as a part of the air, difficult to identify.

"The Absolute Concealment Technique is too powerful, even better than my 'Divine Might'." Lin Feng looked at himself in shock and said incredulously. In such a state, Lin Feng was almost certain that no one could sense his presence.

At the same time, Lin Feng also determined one thing, that is, Gu King Jiang Zheyu had not completely learned the Absolute Concealment Technique. Because, Lin Feng could clearly feel that Jiang Zheyu only needed to integrate the first layer realm and the second layer realm, which was enough to blind anyone's exploration.

During the last battle, Lin Feng sensed Jiang Zheyu's whereabouts one step ahead with Miaomu Mountain's immortal technique, and only then did he defeat Jiang Zheyu step by step. And all this is just because Jiang Zheyu has not even fully comprehended the second layer realm!

Lin Feng's heart was extremely shocked.

In the past, Lin Feng learned from Feng Xingtian that the Thunder Mountain Holy Land was the bloodline and inheritance left by the legendary God of War Chiyou, and he still had great doubts and disbelief. But now, he's convinced it thoroughly.

Perhaps, this Thunder Mountain Holy Land is really the bloodline left by the god of war Chiyou!

This set of absolute concealment techniques alone was far beyond Lin Feng's cognition. You must know that this Absolute Concealment Technique is not an ability, but a martial art that can be obtained through cultivation. However, this kind of martial art is far superior to those so-called abilities, and even spatial abilities cannot be compared to them.

What an amazing spell!

"Perhaps, this is not a martial art at all, but a legendary Tao. Or maybe it's a supernatural power! After recruiting, Lin Feng suddenly thought of the cultivation method that Gu Ling had taught him, and was shocked.

In ancient times, there were too many myths and legends about the god of war. Among them, the most famous is that he is a famous god of war in heaven and earth...... Others have called him a war demon. He is extremely powerful, and even the Yellow Emperor and the Yan Emperor are not opponents. Later, the Yellow Emperor got the Xuanyuan Sword from the Nine Heavens Xuannu, and completely defeated Chi You.

However, although the Yellow Emperor defeated Chiyou, he was unable to kill him. In desperation, I had to divide Chi You's body into nine and seal them in the land of Kyushu!

"Ancient mythology, there are so many mysteries, it's really incredible." Lin Feng muttered to himself.

Thinking of the Yellow Emperor, Emperor Yan, and Chi You, and thinking of the battle for the deer, he recalled the fairy Xin Lan who brought him into the Hokage world and changed his trajectory, and thought of the steps under his feet that were faster than the movement of space, and he was a little stupid for a while.

"What do you want to do so much? It's still too far away for me. After a long time, Lin Feng patted his head vigorously to sober himself up from his thoughts.

"The third engraving should be the highest level of absolute concealment - absolute concealment!" Lin Feng's gaze refocused on the black iron sword, and it became blazing again.

By now, Lin Feng had thoroughly figured out the three-layer realm of the Absolute Concealment Technique. The first level of realm, hidden. The second level of the realm is the accumulation of breath. The third level of the realm is absolutely hidden!

This is a secret technique that is almost against the sky, and it is even better than the "divine might" of the forest wind!

"There are still six hours left before the agreed time, and I don't know if I can fully grasp it." Lin Feng said to himself. His left and right eyes changed again, and one pattern after another was constantly being analyzed and dissected on top of his eyes, and all that remained was the most original thing of the carving.

……

In the blink of an eye, five hours passed.

"Sure enough, can't you perform the exercises at once and comprehend all of this absolute concealment technique?" Lin Feng slowly opened his eyes and said to himself. "However, I also seem to be a little too anxious. You must know that the Gu King Jiang Zheyu is also a rare genius in a hundred years, he has not completely learned it after cultivating for decades! ”

"And I, I've already peeked into the third layer of the realm - an absolutely hidden part of the mysteries, and it's enough to be proud!"

Lin Feng took a deep breath and stood up from the ground. He reached out with his right hand and held the black iron sword in his hand. He had already imprinted the three engravings in his mind, and there was no need to keep this iron sword anymore.

"This sword...... Although it looks like an iron sword from the outside, it is by no means an iron sword. Lin Feng said silently in his heart. He had a guess that this sword was most likely brought out by Jiang Zheyu from the Thunder Mountain Holy Land, and it was a supreme treasure.

However, although he had such a guess about the black sword, Lin Feng did not intend to swallow it privately. He has already gotten what he wants, and if he offends Jiang Zheyu because of this sword, it will be a bit more than worth the loss!
