"Bang!"

With 30% of his power circulating, Qin Feng used this opportunity to smash his zhenqi heavily on the box.

Strangely, there was no change in the box. Even on its surface, the protruding scales were not damaged in the slightest.

Currently, Qin Feng's strength had greatly increased. Even if he only used thirty percent of his power, it was still sufficient to create an incomparably powerful destructive might. He could even shatter a small mountain. It was as terrifying as shattering jade.

"So hard!"

"This box doesn't even have a key …"

"Wait …"

Just as Qin Feng was about to use the [Tyrant Profound Dragon Sword] to give it a try, he suddenly realized that the opening location of this box seemed a little familiar.

Qin Feng's brows twitched as he closed his eyes. He began to ponder unceasingly.

"Heavenly Serpent Sword!"

He suddenly thought of something, the Heaven Serpent Sword!

The Heaven Serpent Sword was the Celestial Snake Palace's most precious treasure. When he killed Lin Kai and seized his dragon aura, he also took away his Heaven Serpent Sword.

As he pondered, Qin Feng swiftly identified the Heavenly Serpent Sword.

"Pah!"

Following the movement of Qin Feng's palm, the hilt of the sword slowly drilled in, followed by a crisp sound.

When the box was opened, a book with strange undulations was inside.

"Sky Snake Clone?"

"What a terrifying aura …"

Such a powerful aura, it could be seen that the person who wrote this book had extraordinary strength. An ancient expert, with a single word, could shake the world and destroy a divine mountain with a single word.

This was because these words contained the will of a powerhouse from the other party. Unfortunately, because of the pa.s.sage of time, these will had gradually dissipated.

Unless there was a mysterious cave like the Lunar Cave of the Buddha peak, the conscients would dissipate sooner or later. However, in this book called Sky Snake Clone, this aura was still as powerful as before, which made Qin Feng somewhat apprehensive.

"I never thought that this Celestial Snake Palace and I were really 'fated' …"

Carefully opening the book, Qin Feng slowly started to read. As he read the contents, Qin Feng's expression gradually became more and more solemn …

Roughly a quarter of an hour later, Qin Feng exerted a little more strength on the book.

Accompanied by a burst of light popping sounds, this scroll had already been grinded into fine powder by his Zhen Qi.

"Phew …"

"What a brilliant martial skill. No, this should already be considered a secret skill …" The Sky Snake Clone could actually use its own strength to create a clone! In addition, this clone is not an illusion, nor is it an illusion.

As he thought of this, Qin Feng's countenance turned extremely heavy.

Such a brilliant Secret Skill would absolutely not be known to anyone else. Creating a clone was not unique in the Heavenly Continent, but every single one of these Secret Skills were enough to make countless experts go crazy for.

After all, with the addition of a clone, whether it was in terms of combat ability or other aspects, it was enough to increase the combat strength of a martial cultivation by multiple times.

The more Qin Feng thought about it, the more astonished he felt.

When placed in this box, one would need to rely on the Heaven Serpent Sword to activate the Sky Snake Clone. The Heaven Serpent Sword is the treasure of the Celestial Snake Palace.

He had actually obtained such a tight item, it was likely that he would be entangled with this Celestial Snake Palace in the future.

"Celestial Snake Palace, let's put that aside for now. I have already memorized the cultivation method on it. Cultivate it for a moment and give it a try!"
