Family heirloom, then turned into a demon girl

Chapter 67 Mission: 11-1 The End of Destruction
In the deepest part of the cave, Li Xiang finally met the demon king named "Pavoni".

It had a blank face without any facial features, and on its head was a golden crown, wedged between two horns, which grew from its body and were stained with blood.

It crawled on all fours, its body covered in emerald green feathers, its wings draped like peacock feathers, gorgeous yet gaudy.

It was surrounded by a pitch-black demonic energy that constantly corroded everyone's bodies, making them upset and wanting to roar and destroy—

So, before they could actually start doing that, Sphinx released her Noble Phantasm.

"In the morning it walks on four legs, at noon it walks on two legs, and in the evening it walks on three legs. What kind of creature is this? Come, answer me!"

She declared loudly: "If not, then become my rations—'Mystery of the Sphinx'!"

Since the other party was a mindless beast, incapable of answering, the riddle's nature was irrelevant. The Sphinx therefore chose the question that had made her famous, maximizing the power of her Noble Phantasm. These words became invisible chains, trapping Pavone within them.

The Sphinx stepped forward alone, waving her hands and manifesting a pair of swords, each bladed with lion's fangs and guarded with feathers. Protected by the pact she had made with Hera, even a young beast like Pavoni could not inflict fatal damage on the Sphinx without solving the riddle. So, she stepped forward alone and swung her swords.

Then a crack appeared on Pavone's blank face, and saw-like teeth were arranged in it. She bared her teeth and let out a terrifying roar at the Sphinx.

The longsword fell. Pavone, who could see the future, naturally tried to dodge, but she was entangled in the chains transformed from the Sphinx's Noble Phantasm, unable to completely avoid it. Its emerald green feathers were torn apart by the lion's fangs, and a dark demonic energy surged out.

As a berserker, Kriemhild was naturally unwilling to just stand there and watch. She brandished the Holy Sword of God's Wrath, igniting poisonous black flames, and chopped it down on Pavone's head.

"Be careful!" Sphinx warned quickly. Her Noble Phantasm's effect was only directed at her. If it was against someone else, Pavone could launch a normal counterattack!
But Kriemhild could no longer hear. As a berserker, she lacked resistance to magic and sorcery, and was the first to be eroded. The undying fire within her would not allow her to lose her will to defy fate, and under the influence of the demonic energy, she could no longer hear the voices of others.

Ignoring the advice of others and insisting on having your own way - this is arrogance.

Pavoni immediately pounced like a wild beast, its sharp teeth biting the sword blade, extinguishing Kriemhildr's poisonous fire. Its claws tore through Kriemhildr's black dress, leaving deep gashes on her shoulders and waist.

At this moment, Ritsuka had borrowed Perseus's invisibility helmet and was quietly lurking in a corner of the cave. Perseus himself had reached into a leather bag that served as his Noble Phantasm, as if trying to take something out.

"Don't be impatient, the time has not come to use that Noble Phantasm yet!"

The Sphinx quickly pushed Kriemhild away, blocking Pavone's further pursuit and at the same time preventing Perseus from using "that Noble Phantasm": "Don't forget, it can't see anything now!"

So Perseus had to put the thing down, stepped on his flying shoes and rose into the air, swinging his sickle far away.

Her class is an assassin. With the aid of several Noble Phantasms, Perseus silently slew the sleeping serpent Medusa, one of the most successful assassinations in mythology. As the Heroic Spirit of the Assassin, Perseus possesses not only the class skill "Breath Severance," which obliterates his own presence, but also Noble Phantasms such as flying boots, a helmet of invisibility, and the scythe of the Undead, making him the most feared assassin in the world. However, while these Noble Phantasms are suitable for Perseus's assassination, none of them possess the ability to release his True Name. Her true trump card is the seemingly insignificant bronze mirror shield.

This Noble Phantasm could only be used once during a Holy Grail War, a pledge she had made when she returned the shield. Therefore, its release could not be lost.

Now, Perseus must wait for his opportunity.

The wounded Kriemhild calmed down a bit. Recalling her pre-battle arrangements, she retreated behind the Sphinx, attacking with only poisonous fire. However, the flames that had always been invincible against Heroic Spirits and demons, refusing to dissipate until their enemies were reduced to dust, quickly faded after leaving her body.

Kriemhild was confused at first, then suddenly realized, and then she was filled with even more intense rage - the power that suppressed her poisonous fire was undoubtedly Pavone's great barrier "Anti-Prophecy". Therefore, the poisonous fire she used to resist fate was, in this ability's judgment, the power of fate.

She finally understood one thing: the true nature of the fire of revenge that had ignited after she obtained the Ring of the Nibelung.

It was a fire destined to consume Asgard and plunge the world into twilight.

Her revenge turned out to be a part of fate.

What is this, a farce?

Ritsuka noticed her abnormality and tried to awaken her through the magical connection between them. However, the deafness caused by the demonic energy affected the mind rather than the body. Filled with arrogance, Kriemhild was unable to listen to anyone.

Ritsuka could only watch as Kriemhild took off the ring in a state of collapse, tilted her head back and swallowed it into her stomach.

According to legend, the fog demon Alberich stole the Rhinegold, kept by the water nymphs, and used this magical metal to forge the Ring of the Nibelung. Whoever holds this ring can control the hearts of others and gain the power to rule the world.

When the gods heard about this, they plotted to steal the ring, so Albelici cursed it, making anyone who held it end up in tragedy. Two giants received the ring from the gods as a reward, and as expected, one died from betrayal, while the other turned into a dragon out of fear of the curse.

The giant's name was "Fafnir".

This is the ring's true curse—just as the opera concludes, the conflict surrounding the ring ends in Ragnarok. Whoever possesses it will be cursed to transform into an evil dragon, heralding the end of the world.

However, if the world is really destined to be destroyed by her hands, it would be a good thing.

Kriemhild's eyes turned into vertical pupils, with golden light shining deep in them. Before she lost the hearts of the people, she could only wish for this: I hope that an unrestrained future will be born at the end of fate.
