Fantasy: I have a return system with ten thousand times the effect of cultivation

"Clean the battlefield, I'll go to the underground world!"

After incinerating the eldest prince Zhao Han and other dignitaries of the empire into ashes, Yang Feng gave an order in the direction of Black Rock City, and with a movement of his body, he turned into a streamer and galloped towards the direction of the underground world.

The world of origin is vast and boundless, whether it is the ground, the underground, or the sky, there are a large number of intelligent life inhabited.

Among them, the human race and demon race mainly live in the ground world, the underground demon race mainly lives in the underground world, and the extraterritorial sky demon and angel race mainly live in the sky.

The aura of origin of the Dagan Empire is extremely thin, and the number of strong men is very rare, and the strongest have only the strength of cultivation base that has transformed into nine transformations.

As for the underground world corresponding to the Dagan Empire, the underground magic energy is also very thin, and the number of strong people is also very rare. The strength of the strongest is not very strong, but it is one level higher than the strongest of the Dagan Empire. Possesses the power of immortality.

And this is also the main reason why the Dagan Empire sealed the passage leading to the underground world.

If the strength of the Daqian Empire far exceeds the corresponding underground world, not only will it not seal the passage leading to the underground world, but will send a large number of strong men to enter the underground world to seize the minerals and other resources of the underground world.

After all, the underground world is extremely rich in minerals and other resources, which is a great fortune.

Of course, for the underground demons in the underground world, the people, monks, monsters, spiritual herbs, minerals and other resources in the territory of the Dagan Empire are also a great wealth, which can increase the cultivation of the underground demons Strength, not to be let go.

And this is also the motivation for the underground demons to invade the Dagan Empire.

While thinking about it, Yang Feng flew to the place where the passage between the Daqian Empire and the underground world was located. More than ten thousand powerful demon warriors and more than ten demon warriors in the mortal realm entered Yang Feng's field of vision.

"Kill that human kid!"

Seeing Yang Feng appearing near the passage, a demon powerhouse who had transformed into nine transformations, a fierce light flashed in his eyes, and he ordered loudly.

Immediately afterwards, more than a dozen powerful demon clansmen in the Mortal Transformation Realm flew away one after another, turned into streaks of light, and headed straight for Yang Feng.

During this process, strands of demonic energy gushed out from the bodies of more than a dozen strong demons in the Transmortal Realm, and condensed handfuls of terrifying demonic soldiers, bombarding Yang Feng's body, intending to kill him on the spot.

Facing the attacks of more than ten demon soldiers, Yang Feng's expression remained unchanged. With a wave of his hand, thunder and lightning took shape in the void. With destructive power, he met more than ten demon soldiers and collided with them. .

boom!boom!boom!

Amidst the violent roars, more than ten magic soldiers were destroyed by thunder and lightning.

Immediately afterwards, thunder and lightning flashed across the void quickly, bombarding more than a dozen strong demons in the Mortal Transformation Realm, killing them on the spot and turning them into charred corpses.

"Human Leixiu!"

Seeing the thunder and lightning that blasted and killed more than a dozen demon powerhouses in the metamorphosis realm, the face of the metamorphosis demon powerhouse changed drastically, and he couldn't help exclaiming.

When the Nine-Transformation powerhouse exclaimed in alarm, Yang Feng thought, and thunder and lightning condensed in front of him. With destructive power, they shot towards the Nine-Transformation powerhouse Bombarded away.

Seeing the thunder and lightning approaching rapidly, the transformed demon powerhouse hastily aroused the demonic energy in his body, condensed demonic energy shields one by one, made them stand in front of him, and quickly retreated, trying to Hide in the space channel.

However, the thunder and lightning were extremely fast and powerful, easily destroying the shields of demonic energy one by one, and bombarded the strong man of the Nine Transformations Demon Race with undiminished force, killing him on the spot.

"Destroy it all for me!"

At this time, Yang Feng cast his eyes on the thousands of demon warriors, and with a soft drink, thunder and lightning formed in the void, like a thunderstorm, and bombarded the thousands of demon warriors.

boom!boom!boom!

Amidst the violent roars, each demon warrior was killed by the thunder and lightning, and turned into pieces of fly ash.

In the blink of an eye, more than ten thousand demon warriors were killed by the thunder and lightning, and all of them turned into fly ash and scattered with the wind.

At this time, Yang Feng entered the space channel with a flicker.

After flying in the space passage for a while, Yang Feng came out of the space passage and came to the desolate, silent, vast and boundless underground world.

"It's amazing that there is a blood moon in the underground world!"

"It is said that the blood moon in the underground world is the source of power for the demons below, nourishing countless underground demons. I don't know if it is true or not!"

Looking up at the blood moon in the sky, Yang Feng muttered softly, and with a movement of his body, he flew towards a faintly visible palace in the distance.

According to Yang Feng's understanding, the territory of the underground world corresponding to the Dagan Empire is no smaller than that of the Dagan Empire, and even slightly larger than that of the Dagan Empire. The number of underground demons is hundreds of millions, far exceeding that of the Dagan Empire. s population.

At the same time, in the territory of the underground demons, there are a large number of mineral resources, as well as various special products of the underground world.

Therefore, Yang Feng is going to surrender the ruler of the underground demon clan, the demon king in the nearby area, and make him his slave, to provide the Yang family of the Dagan Empire with a large amount of minerals and specialties in the underground world, and increase the resource reserves of the Yang family of the Dagan Empire , to enhance the comprehensive strength and heritage of the Yang family.

When Yang Feng was flying in the underground world for a while, he met some demon warriors.

After seeing Yang Feng, these demon warriors immediately attacked Yang Feng without the slightest hesitation, intending to kill and devour him.

However, these demon warriors were easily suppressed and killed by Yang Feng as soon as they made a move.

In this way, Yang Feng easily killed the demon warriors blocking the way one by one, and easily arrived at the location of the demon king's palace.

At this time, the Demon King, who had already received the news, came out of the Demon King's Palace, looked at Yang Feng suspended in the void, and said in a cold tone: "Human monk, how did you enter the underground world?"

Hearing the Demon King's words, Yang Feng said in a flat tone: "I killed all of your underground Demon Race's army that entered the Dagan Empire, passed through the space passage, and killed countless Demon Race warriors blocking the way, all the way here!"

"Human boy, you actually killed our army of underground demons, you deserve to die!"

As soon as Yang Feng's voice fell, the devil's eyes flashed fiercely, and he roared loudly.

In the midst of the roar, the demon king incited the mana in his body, urged a long spear full of demonic energy, and stabbed at Yang Feng's body, trying to penetrate Yang Feng's body and make him die tragically.

Faced with the demon king's spear attack, Yang Feng's expression remained unchanged, his right hand was clawed, and he went straight to meet it.

Card wipe!

Accompanied by a crisp sound, Yang Feng grabbed the spear with his right hand, and easily smashed the spear into pieces, which splattered all around.

Immediately afterwards, with a flicker, Yang Feng approached the Demon King's side, stretched out his right hand, and grabbed the Demon King's neck. Terrifying power of thunder and lightning gushed out from Yang Feng's body and entered the Demon King's body. Destroying its body wantonly, causing it to make screams of incomparable misery.

"Don't kill me! I am willing to surrender to you, serve you, and become your slave!"

Feeling the cold murderous intent coming from Yang Feng's body, as well as the flesh and blood vessels in his body being constantly destroyed, the Demon King's face changed drastically, a flash of fear flashed in his eyes, and he immediately begged for mercy loudly.
