There are also two leader-level demons among the Hell Demons, one is a mage-type Hell Witch, who single-handedly killed all of Wu Yi's skeleton mages, and her firepower is really powerful.

The other is the Abyss Flame Demon, this demon with a body composed of hell flames and the six-armed snake demon are inseparable, and his hand-to-hand combat ability is actually no less than that of the six-armed snake demon, and he is definitely an extremely strong enemy.

However, Wu Yi's transformation effect in the current Thunder Roar state has not been lifted, and he can still hold on for a short time by relying on the Five Fowl Opera, and he cooperates with the control skills of many summons to surround the Hell Witch.

This witch has a lot of life-saving skills, but under the siege of everyone, she can't escape back to hell, it can be said that there is no way to escape, and after the escape skills are forced out, she was seized by the two-headed snake vine and used a joint strangulation.

The strength of the Two-Headed Snake Vine is much higher than that of the Hellwitch, and the Witch has no hope of breaking free under the bondage of the Two-Headed Snake Vine.

After Wu Yi put a demon slayer mark on the Hell Witch, each of his attacks would make the Hell Witch wail in pain, and the divine damage triggered by the demon slaying mark on her body burned a pitch-black wound, causing damage and subsequent effects far more than ordinary 100 damage.

Under the mark of the demon slayer, the Witch of Hell became extremely vulnerable, and after being ravaged by the roar of thunder, she was quickly smashed into a pile of rotten flesh, and she could no longer die.

Seeing that the Hell Witch had also died, the Abyss Flame Demon knew that his death was not far off, which also inspired the demon's ruthlessness, and he began to burn himself and turn into the state of the Chaos Flame Demon. The infernal flames that enveloped the whole body were simply unapproachable.

However, Wu Yi had just experienced the purgatory body of the Fallen Purgatory Flame, and his resistance to the flames had been greatly improved, and the survivability of the Thunder Roar was extremely strong, so he simply carried the Flame Giant Sword of the Abyss Flame Demon and fought against him.

After activating the Thunder Shield again, the Abyss Flame Demon couldn't even break Wu Yi's Thunder Shield, but instead frequently triggered forked lightning, which was splashed with flames by continuous lightning, and the energy was rapidly consumed.

The divine damage triggered can quickly cancel out the flames on the Chaos Fire Demon's body, which is simply harming the Fire Demon's origin.

Finally, after the ground of the Burning Valley was scorched to earth, the Abyssal Flame Demon was finally besieged to death. The fire demon's tall body fell to the ground with a heavy blow. The corpses that lost their lives turned into countless flying ashes, and disappeared with the wind.

After the death of the Abyss Flame Demon, Wu Yi finally killed all the hell demons, and the eighth layer of the ladder challenge was also broken by Wu Yi.

This time, because he wanted to prevent the formation of the Gate of Hell, Wu Yi could be said to have seized the time to clear the Hell Demon. It took less time to fight than it did before against the Zerg Hive. Less than two hours. This thrilling battle is complete.

Because the powerhouses of the Demon Lord's level have all made a move, Wu Yi also successfully retreated from the other party's hands, and the main god has a high opinion of Wu Yi's battle this time. Wu Yi has once again obtained a Legendary-level treasure chest!

Wu Yi was very excited to open this treasure chest, and found that there was a blue jade Tongtian card and a black crystal inside, and there were demon words flashing out in the crystal, and they disappeared quickly, it seemed to be an item or prop related to demons.

Fragments of Hell's Gate: Legendary Grade. The Hell's Gate Fragment has the ability to communicate with Hell, and Dark Summoners can consume this Fragment to summon powerful Hellish Demons and even Demon Legions to help Summoners sweep away their enemies. You can also cultivate the fragments of the Hell Gate into a real Hell Gate, which can make the Hell Gate a gateway to Hell and completely communicate the two worlds, but be careful that the demons are extremely cunning, and after opening the Hell's Gate, you may encounter the fate of being killed by a pit.

Note: The Hell Gate Fragment was originally a Hell Gate seed, and after the Hell Gate was shattered, it left behind the most complete Hell Gate Fragment, and it also has a certain spatial power, and it is no problem to temporarily open a space-time rift leading to Hell.

After Wu Yi saw this fragment of the Gate of Hell, he was stunned in his heart, this fragment may be the reward he received for breaking the Gate of Hell, after all, he paid a lot of price for breaking the Gate of Hell, and it is understandable for the Lord God to compensate him.

However, Wu Yi held this fragment of the Gate of Hell, but he didn't know how to use this legendary-level prop.

If you take the pieces of the Gate of Hell to auction in the Tower of Babel, I believe that they can be sold for a good price, and the pieces of the Gates of Hell can be used to summon the demons of hell, like any dark sacrifice, the reincarnation of the dark summoner and other professions can exert a strong effect.

Even if it falls into the hands of some ambitious reincarnation, he can use it to cultivate into a real hell gate, opening a portal to the world for the hell demons, and a world may be ruined because of this, which can be regarded as a killer level prop.

Wu Yi himself could barely use this fragment normally, he provoked the demon lord, making the demon lord hold a grudge against him, and even left cruel words, sooner or later, Wu Yi would be killed.

Because there are countless hells, different hell gates are also connected to different hells, and the fragments of this hell gate are probably connected to the hell where the demon lord is located, if Wu Yi rashly opens the space-time rift, it is likely to be an act of seeking death.

Just as Wu Yi was considering whether to return to the Tower of Babel and sell this piece of Hell Gate, the elf seemed to know what he was thinking, and appeared beside him and said, "Young man, this piece of Hell Gate is very useful to you." ”

Wu Yi glanced at it and said, "Yes, even if I can summon some hell demons, it may also attract the revenge of the demon lord, I don't want to be hunted down by the demon lord because of a small loss." ”

The elf smiled and said, "What I said is not a normal usage, you have obtained a miniature space-time wormhole before, plus this fragment of the hell gate, if you are willing to consume soul crystals, you can fuse these two items into the death passage attached to your death graveyard, so that the death passage is upgraded to the door of the dead." ”

Wu Yi said with some doubts: "Can you still use it like this?" But what is the difference between the door of the dead and the passage of death, they are only used to connect the two worlds, and the passage of death is enough. ”

The elf replied: "I have already said before, the upgrade system is omnipotent, as your strength increases, the functions of the upgrade system will also increase, only you can't think of it, there is no upgrade system that can't be done." ”

Wu Yi: "......"

The elf didn't bother to comprehend Wu Yi's surprised expression, and it continued: "Let's not talk about this for a while, I'll introduce to you the advantages of the Gate of the Dead compared to the Death Passage." ”

"You've already used the Death Passage before, and you know that it can hold for half an hour, which is enough to drown an enemy in the endless sea of skeletons."

"But the duration of the death passage is still too short, the buffer time is too long, and the usefulness is limited, but the door of the dead is different. The Gate of the Dead is similar to the Gate of Hell, it is a formal gateway to communicate directly between the two worlds, it is very stable and strong, and the duration far exceeds that of the Death Passage, and the buffer time will be greatly reduced. ”

"You can also understand the difference between the Gate of the Undead and the Passage of the Dead from the point of hell and the passage of hell, the demon lord can cross the border from the gate of hell, while the passage of hell can only teleport demons with the highest level of leader."

Wu Yi interrupted the elf's words and said, "In other words, the door of the undead can make more powerful undead be summoned?" But my Skeleton Soldier and Skeleton Mage are only Boss or Genius level summons, and the strongest Skeleton Shooter and Skeleton Warrior have only reached the hero level, so what's the use of me needing the strong endurance of the Gate of the Dead. ”

The elf explained unhurriedly: "This is the second benefit of the Gate of the Dead that I want to say, after establishing the Gate of the Dead, the Gate of the Dead will automatically absorb the breath of the surrounding undead, whether it is the concentration or the number is far beyond the previous level, your Graveyard of the Dead can grow greatly, and even your Graveyard Rune of the Graveyard will evolve into the Rune of the Realm of the Dead." ”

Wu Yi: "! ”

Elf: "Don't be surprised, Rune Language is not only upgraded by adding more runes, but if the effect of the skill you inlay Rune Language increases, Rune Language will also be fed back and improved." ”

"Before, you devoured the energy of the Thunder Crystal, and the effect of transforming into the Thunder Roar skill increased, and your Thunder Fury Rune also increased, which is also the reason!"

Wu Yi nodded and said, "So that's the case, what are the benefits of the Death Cemetery after it grows into a realm of the undead." ”

The elf sold a pass and said, "This can only be seen when you really make it evolve into the realm of the undead, but what I can tell you is that there are all kinds of powerful undead in the realm of the undead, and your skeleton summon is just one of them." ”

"You have to compete and fight to survive in that world, so your skeleton summons will definitely grow faster than they do now."

"When you open the door of the undead and summon helpers, many undead in the realm of the undead will respond to your call and cross over to help you fight, and even form an army of the undead."

Wu Yi's eyes lit up: "All kinds of powerful undead creatures!" I like this. ”

The elf said with some taste of successful conspiracy: "Since you like the undead legion very much, just leave the fragments of this hell gate, it is also essential to consume a large number of soul crystals, you have to be mentally prepared." ”

Any operation of the upgrade system is inseparable from soul energy and soul crystals, these two are the power source of the upgrade system, in the battle on the first eight floors of the ladder, Wu Yi obtained enough soul energy and soul crystals to do some big moves as he imagined!
