Without thinking too much, Su Yehan asked again: "System, how can I use the Scarlet Divine Sword to increase the power of the Silent Void Yuan Slash?"

"The host only needs to refine the blood-colored divine sword and integrate it into itself, which can increase the power of the Void Void Slash, however, given that the host's strength is too weak now, it only needs to consume 10 million energy points, and the system can help the host increase the power of the Void Void Slash!"

"Then consume 10 million energy points!" Su Yehan said without hesitation.

10 million energy points, that is, the energy value consumed by releasing a Netherworld Destruction Light, is nothing to Su Yehan now.

Of course, let alone 10 million points, it is 100 million points, 1 billion points, 10 billion points, Su Yehan will agree without hesitation.

Because as he hunted more and more tenth-level giant beasts, he found that the strength of the tenth-level giant beasts he encountered was also improving little by little.

Just like the previous Baqi Snake, if it weren't for Su Yehan's extremely strong physique, he might have fallen at this time.

The next moment, the blood-colored divine sword floating in front of Su Yehan suddenly disappeared, and Su Yehan knew that this must have been taken away by the system.

Sure enough, just a few breaths later, the system's prompt sounded in Su Yehan's mind.

"Ding! Congratulations to the host, the power of the Void Element of Silence has been greatly improved, please check the detailed attributes of the host!"

Then, Su Yehan's attribute panel appeared in front of him, Su Yehan's eyes fell on the skill column, and the Void Yuan of Silence was slashed, and the next moment, the detailed information of the skill appeared in front of him.

Silent Void Slash, the host can send out wolf-shaped blades through his eyes, and every time he uses this skill, he needs to consume 50 million energy points!

Now the details of the Void Void Slash are basically the same as before, but the difference is that the energy value consumed per use has risen from one million to fifty million points!

"Compared to before, the power of the Silent Void Yuan Slash has increased by fifty times!" Su Yehan was very surprised, he didn't expect that the blood-colored divine sword could actually increase the power of the Silent Void Yuan Slash so much.

"Even compared to the Light of Nether Destruction, it's five times stronger!"

Su Yehan was very excited, and then, the wolf body left the underwater cave and headed upward.

A few minutes later, Su Yehan had already reached the air, without the slightest hesitation, his eyes flashed, and then he only heard two clanging sounds, and two wolf-shaped blades came out.

However, unlike before, the wolf-shaped blades that were issued by using the Silent Void Yuan Slash before were all black, and now, these two wolf-shaped blades became blood-red, just like the blood-colored wolf shadow in Su Yehan's scale armor.

"Boom!"

In the next moment, two wolf-shaped blades crossed together in the air, forming a cross shape, slashing at the void in front of them.

There was a bang, and the next moment, the space began to shatter.

Then a spatial crack appeared that was nearly a meter wide.

"Haha, the Silent Void Yuan Slash after the ascension is really powerful!" Su Yehan looked at the spatial crack in front of him that was beginning to heal slowly, and was very satisfied.

"If you meet the Yaqi Great Snake now, you can easily kill it by relying on the Silent Void Yuan Slash!" Su Yehan thought.

"My current energy value has reached 85.5 billion points, and I am only 14.5 billion points away from evolution, and I can get it by killing two level 10 giant beasts!" Su Yehan looked at his energy value and thought.

The next moment, the speed exploded, and the wolf's body turned into a black light, and it quickly disappeared.

Half a month later, Su Yehan flew in the area of the Dongzhou Alliance.

In the past half month, he had not encountered a single rank 10 giant beast.

In the past half month, the world's environment has further deteriorated, according to Su Yehan's estimates, the original 10 billion population has been reduced by one-fifth, that is, 2 billion, and this is still the least.

Of course, Su Yehan didn't care much about these, but he didn't take the initiative to attack the human race.

On this day, Su Yehan flew to the sky above the endless mountain range, and when he looked at it, the mountain range below was full of plane trees.

"Fengluo Wutong, here, is there a phoenix!" Su Yehan looked at the plane trees all over the mountain, thinking in his heart, the next moment, the powerful perception ability spread, and sure enough, two hundred miles ahead, there was a powerful existence, it was a blood-red fire phoenix!

"Chirp!"

At this moment, a phoenix roared, and the fire phoenix rose into the sky, also towards Su Yehan.

"The phoenix has appeared, I don't know, will I meet the legendary dragon next time!" Su Yehan's speed exploded, and the wolf body rushed forward.

A few minutes later, in Su Yehan's sight, the figure of the fire phoenix appeared.

The body shape of the fire phoenix is the same as that of Su Yehan, it is all in the kilometer, and the whole body is fiery red, and on the surface of the body, blazing flames keep appearing.

"Chirp!" The fire phoenix looked at Su Yehan, let out a chirp, its huge mouth opened, and a blazing flame came towards Su Yehan.

Everywhere the flames passed, the space rippled.

When Su Yehan saw this scene, he could be sure that the strength of this fire phoenix would definitely not be weaker than the Baqi Great Snake, or even stronger.

Of course, Su Yehan was not afraid of her, because of his skills, the power of the Silent Void Yuan Slash had been greatly improved.

"Netherworld Destruction Light!" Su Yehan's killing eyes flickered, and the dark matter in it instantly communicated with the Netherworld, and then a terrifying black light emitted, heading towards the blazing flames that came quickly.

"Boom!"

In the next moment, the Netherworld Destruction Light collided with the blazing flames, erupting with a loud bang, and then, the two energies were annihilated.

"Let you see the power of the Silent Void Yuan Slash!" Su Ye laughed coldly, his eyes flashed, and he only heard two clanging sounds, and two wolf-shaped blades sent out, slashing towards the fiery phoenix.

The blood-red wolf-shaped blade was terrifyingly powerful, and everywhere it passed, the space was cut into a crack of nearly one meter.

"Chirp!" The fire phoenix's eyes felt the power of the Silent Void Element, and let out a chirp, and then, two red rays suddenly erupted from its eyes, slashing towards the Silent Void Element.

"The strength of this fire phoenix is really stronger than that of the Baqi Great Snake!" Su Yehan looked at the two red rays in the eyes of the fire phoenix, and even bombarded the space with a crack of nearly a meter or so.

"Boom!"

In the next moment, the two wolf blades and the two red rays collided together, erupting with a deafening sound, and at the center of the collision of the two energies, the space shattered into a crack of nearly ten meters.

"Spear of Destruction!" At this moment, Su Yehan's heart moved, and the Spear of Destruction in the system warehouse suddenly appeared above the head of the Fire Phoenix, and then stabbed violently.
