Start by logging into the Old Man's Ring at Hogwarts

He rushed over to investigate the situation.

Perhaps I can take this opportunity to descend to the human world and cause trouble for Zicomo.

With this in mind, Thanatos arrived at the location of the spatial passage.

Thanatos then discovered that Zikomo, whom He wished He could tear to pieces, was standing in front of the spatial passage.

And it was even smiling and waving at Him.

After crossing the stone gate, Zicomo did not wander around, but stood still and waited.

He knew Thanatos would definitely sense the commotion here and come to investigate.

Sure enough, Zicomo met Him not long after.

Hi! Good evening, I've come to find you.

Zicomo smiled and waved to Thanatos as a greeting.

However, Thanatos was not buying it.

"Mortal, how dare you come to the Underworld! You're practically courting death!" Thanatos roared furiously. "I don't know who gave you the courage!"

Zicomo waved his hand and said, "It's just that you killed one of your avatars in the human world, is it really necessary to be so angry?"

Thanatos almost laughed out of anger at Zicomo's words.

Is this a problem with incarnation?

For an incarnation like Voldemort, he wouldn't care how many Thanatos die.

What he cared about was that Zicomo had stolen his authority.

Thanatos said no more and raised his scythe to strike Zicomo.

"Hey, hey, don't be so angry!" Zicomo quickly stopped him. "At worst, I'll just give the power back to you."

Thanatos paused, his scythe momentarily halting.

He asked with some skepticism, "Really? You would be so kind?"

Zicomo nodded repeatedly and said, "Of course, I didn't want this in the first place."

Thanatos said, "I don't believe it."

Thanatos did not trust Zikomo's words.

This is something that, if fully mastered, can become the authority of a god.

Thanatos did not believe that Zicomo would not be tempted at all.

“I’m serious,” Zicomo said. “I just had some power over death, and this thing just suddenly appeared on me.”

"Moreover, it also conveyed a message to me that as long as I fully grasp this power, I will have the opportunity to become the Grim Reaper."

"But all I want in this life is a happy and harmonious family. I have no desire to become a god."

Thanatos remained skeptical; Zikomo's reasons failed to convince him.

Seeing that Thanatos still did not believe him, Zicomo added, "If you don't believe me, I can swear an oath of my soul."

Soul oath is an ancient form of magic that requires the user to swear an oath with their soul.

If the user fails to fulfill the oath, their soul will be scattered.

Due to the severe punishment and the extremely high difficulty of casting the spell, this magic has long been obsolete.

Few people in the wizarding world know about this magic anymore.

Zicomo also found this magic in the Malfoy family's library.

However, a god like Thanatos, who has lived for countless years, would naturally have some understanding of oaths of the soul.

Thanatos said, “In that case, swear an oath.”

Zicomo nodded and, after chanting an extremely long incantation, began to take an oath.

“I, Zicomo, swear by my soul that if Thanatos answers three questions to me, I will return the power of death to Him.”

Thanatos frowned upon hearing this and said, "You didn't say before that I would answer your questions."

Zicomo said, "I'm the kind of person who prefers equal exchange. And this isn't just to make you believe me; I genuinely want to return the power to you!"

Thanatos thought Zicomo made sense.

Indeed, if Zicomo's oath was to unconditionally return authority to himself...

Then He should consider whether Zikomo is truly sincere.

Thanatos said, "In that case, go ahead and ask whatever questions you have."

Thanatos decided, based on Zikomo's next questions, whether or not to let Zikomo die a little easier.

Yes, even if Zicomo made a vow in his soul to return the power to himself.

Thanatos still did not give up his murderous intent toward Zicomo.

This is what Zicomo taught Him: all's fair in war.

Zicomo asked, "My first question is, are your gods born this tall?"

At this time, Thanatos is depicted wearing a black robe, with wings on his back, and holding a scythe.

His body was over a hundred feet tall.

Zicomo was not even as big as a finger joint compared to Him.

Thanatos thought Zikomo would ask some tricky questions, but to his surprise, he asked this one.

He replied, “No, this form is merely my physical manifestation as a deity.”

"Can you transform into a human form?" Zicomo asked. "To be honest, it's quite tiring talking to you while looking up at me."

Thanatos's lips curled slightly beneath his black robe.

He said, “Okay, this is your second 4.5th question.”

Before Zikomo could refute, Thanatos transformed into a normal human-sized form.

This is what a soul oath is like: as long as the actions meet the conditions, then it is equivalent to fulfilling the requirements of the oath.

There were too many loopholes to exploit, which is one of the reasons why this ancient magic was abandoned.

Zicomo frowned slightly, seemingly not expecting Thanatos to resort to such a trick.

Thanatos reminded him, "Hurry up, you have one last question."

Zicomo remained silent for a long time before finally speaking slowly: "You should still remember the last few words I said to you during the day, right?"

"Of course I remember, is there a problem?"

Thanatos didn't know why Zikomo had suddenly asked that question.

Chapter 318 Death Meets His End, the Truth is Exposed

Thanatos naturally remembered what Zicomo had said during the day.

He clearly remembered that Zicomo said he would fight his way to the underworld and that he would pierce His heart.

In the end, he still had to obediently return the authority to himself under the influence of the soul oath!

Thanatos suddenly realized something was wrong.

Zicomo's transformation was so drastic that he not only made a soul oath that was detrimental to him.

Moreover, the questions asked were mostly irrelevant.

Realizing this, Thanatos knew something was wrong, but it was too late.

Zicomo nodded in satisfaction at Thanatos's answer.

“Good that you remember,” Zicomo chuckled. “So, are you ready to face the blade piercing your heart?”

As Zicomo finished speaking, a double-helix scimitar pierced Thanatos's chest from behind.

This knife is the 'Hunter's Finger Knife', and the person wielding it is Lani.

Zicomo had already discussed this with Lani back in the "Zen Garden".

He himself entered the underworld openly, while Lani hid herself using an invisibility cloak.

The two acted in the open, one in the shadows. Zicomo attracted Thanatos's attention in the open, while Lani hid in the shadows, waiting for her chance to strike.

This is Zicomo's plan against Thanatos.

Thanks to their mutual understanding, Zicomo successfully created an opportunity for Lani to assassinate Thanatos.

Thanatos lowered his head, staring blankly at the blade that had pierced his heart, his eyes filled with disbelief.

Thanatos, residing in the underworld, is like Zicomo in his own "Zen Garden."

They were practically invincible and omnipotent.

Even when he suffers a fatal injury, Thanatos can recover from it using the rich death power and soul energy of the underworld.

It can be said that as long as the underworld exists, He will not die.
