"Hmph, just Lei Jiao, go to death for me!!"

The Black-winged Bone Demon King snorted coldly, took out a piece of the upper artifact [Thunder-sucking Box] engraved with countless thunder and lightning spell seals and opened it directly, crazily activate the power of the upper demon king.

A terrifying suction force surged out of the [Thunder Box], forming an extremely huge vortex that floated in the void.

The lightning streaks that struck from the sky were directly sucked in by the [Thunder Box].

The body of the thunder dragons emitting the aura of terrifying power in the median demon level in the thunder clouds trembled slightly, and turned into thunder lightning and directly penetrated into the [Thunder-absorbing box] and was directly absorbed.

Originally, the dozens of median demon-level thunder and lightning dragons could join forces to deal with a slightly weaker upper demon like the scale-armored Demon King. However, the Black-winged Bone Demon King specially prepared the [Thunder Box] to restrain their artifacts so that they could easily suppress them.

A hint of joy appeared in the eyes of the Black-winged Bone Demon King: "Good harvest!"

After absorbing dozens of thunder and lightning dragons, as long as the power of the demon king is consumed for a certain period of time, it can exert a thunder and lightning attack comparable to that of the upper demon king. This will give the Black-winged Bone Demon King another powerful attack method.

In order to obtain this superior artifact [Thunder Box], the Black-winged Bone Demon King paid a considerable price.

A series of terrifying auras of the Void Demon King level came from all over the world.

"Who are you? This is the world of His Majesty the Thunder Demon God of Huangtianye!! Only His Majesty the Thunder Demon God of Huangtianye and His Heirs can enter here! You should leave this place quickly, otherwise there will be only a dead end!!"

A strong man with mysterious thunder patterns engraved all over his body, tall and handsome, with a thunder pattern on his forehead. A pair of thunder wings behind him walked out of the void with a thunder trident in his hand, and looked at the Black-winged Bone Demon King and shouted loudly.

"The Wilderness Thunder Demon Clan! The powerful race that once dominated the Wilderness Thunder Demon Region! Unfortunately, the Wilderness Thunder Demon God has fallen! The Wilderness Thunder Demon Clan outside has also been exterminated. I didn't expect that I could even see you remnants here!!"

"It just so happened that I killed them all!! The Black Resentful Demon God offered a high reward to the heads of you, the Demon Clan, and even I was moved by those bounties!"

"Do you do it and kill them all!"

The black-winged bone demon king had a fierce light flashed in his eyes and shouted sternly.

Behind the Black-winged Bone Demon King, a king of the Void Demon used the great demons of the Void Demon to use various secret attacks and killing techniques to fight with the powerful men of the Wild Thunder Demon Clan.

Countless sharp bone blades appeared all over the body of the Black-winged Bone Demon King. Holding the bone sword, he was like the most fierce and vicious peerless swordsman, using his peerless sword technique to attack the leader of the Wild Thunder Demon clan holding a trident of lightning.

Boom! Boom! Boom! Boom!

The terrifying explosion sounded shaking in this area.

The Black-winged Bone Demon King was originally slightly stronger than the leader of the Wild Thunder Demon Clan. He also owned the top-level artifact [Thunder Box], which tightly restrained the leader of the Wild Thunder Demon Clan who held the power of thunder. When the two sides fought, he completely gained the upper hand.

The combat power of the other Thunder Demon Clan is also amazing, but their thunder power is completely restrained by the Black-winged Bone Demon King's [Thunder Box], and the ten-cost thing is not exerted by the strong men brought by the Black-winged Bone Demon King.

"What a fool! He actually fought with those Demons of Demons! I'll take one step first!"

A sarcastic look flashed in the eyes of the Black Flame Demon King, and his breath was hidden, like a ghost, passing through the thunder clouds and coming to the holy castle that was 10,000 meters high.

The sacred castle, which was 10,000 meters high, was integrated into one, exuding a sacred and great aura of terror without a trace of flaws.

"Display it for me!!"

The Black Flame Demon King appeared at the top of the sacred castle, his eyes flashed with fierce light, and he held a black flame demon sword in his hand. The power of the Demon King was boiling, and he slashed on the sacred castle with a crazy sword.

The Black Flame Demon King also obtained many treasures, many of which were forcibly split by him and plundered the wealth inside.

Boom!!

A earth-shaking loud noise sounded, and countless mysterious thunder patterns emerged in the sacred castle carved with Thunder God Jade.

Thunder patterns shine, forming an extremely terrifying thunder barrier.

The Black Flame Demon King slashed the thunder barrier with one sword, causing ripples.

Boom!!!

The lightning light shone in the thunder barrier, and a white lightning as thick as a bucket contained a trace of terrifying power fluctuations of the demon level, instantly slammed on the body of the Black Flame Demon King.

"No!!"

The Black Flame Demon King screamed, his body retreated suddenly, and the film of the Demon King protecting his body collapsed, and his lower body was directly qinized under the bombardment of white lightning. His soul vibrated violently and his breath plummeted.

The Black Flame Demon King did not hesitate to directly use the secret technique, turned into a black flame, and fled to the distance. He was backfired by the sacred castle and was seriously injured. If he continued to stay, he would have only one way to die.

"Reckless idiot!!"

A joke flashed in the eyes of the Black-winged Bone Demon King, and he suddenly waved his hand.

A bone spur shrouded in a layer of black vortex directly hit the black flame transformed by the Black Flame Demon King like lightning.

The black flame collapsed directly, turned into flames and continued to flee outside.

The Black Flame Demon King was once again severely injured.

"The impact of the Nether Water!"

A middle-level demon king who held the power of water, the Demon King of Mingshui smiled and activated the power of the demon king. A terrifying dark water that could erode everything directly brushed into the sky.

The black flames transformed by the Black Flame Demon King were wiped out by the dark water and then extinguished in groups.

When the last ball of black flame was extinguished, the Black Flame Demon King lost two-thirds of his body and appeared in the ball of dark water, struggling shrillly.

"Stop it!! Black-winged Bone Demon King, spare my life!! I can serve you for thousands of years!! Please spare me and never die!!"

The Black Flame Demon King struggled wildly in the dark water and screamed shrillly.

"Black Flame Demon King, you kill my subordinates. The crime is extremely evil, there is only one way to die!! Go and die!"

The Black-winged Bone Demon King smiled, and the Demon King's power was boiling. A black bone spur pierced through the dark water like lightning, and penetrated through the Black Flame Demon King's head.

"Source energy is 15 billion, powerful divine power 20, and divine soul 20."

As soon as the Black Flame Demon King died, a line of prompt messages suddenly appeared in Shu Feng's eyes.
