Eternal Thief

After discussing their course of action, Winter left the small shop and headed toward the Blood City instead of starting with the All-Devil City. She chose to target the city of hunters because it would divert the attention from Ace in All Devil City. 

As for Ace, he closed the shop and used his Qi to dig an underground chamber before sealing it with all sorts of formations. Once he was done, he opened the system shop and bought the Elixir of Darkness for 50 million TP, which he was putting up on hold up until now. 

He didn't dare to use it before because its effect was unknown, and he still needed to chase after his target. He was waiting for this kind of opportunity to arise, and now that his targets were literally immobilized, he didn't need to worry about anything. 

Furthermore, he didn't want to underestimate his targets just because they weren't as strong as the Union Lord. In fact, those guys were living legends, and to go against them, he needed everything he had. 

The Elixir of Darkness was a special reward he got that could help him in Heaven's Stealer Mission, so not using it was nothing but idiocy. 

The moment he bought the Elixir of Darkness system's voice sounded, 

=====

[Elixir of Darkness (Grade???) has been successfully purchased!]

[Description: Enter Darkness to Experience Darkness] 

[Caution: Because of [Natural Order], the Elixir of Darkness cannot be revealed in Mortal Sky Heaven!]

[Do you want to consume it directly?]

[Proceed/Later]

---

[Thief Point(s): 569,450,100]

=====

Ace was startled by this unexpected notification. He knew about the [Natural Order] because of Eva's special case. But it was his first time seeing something that could make the [Natural Order] react. Not to mention, he was supposed to consume it. 

"System, just what is this Elixir of Darkness and its effect? Is it safe for me to consume it here?" Ace questioned sternly. If before he was only thinking about this thing as an extraordinary medicine, now that notification changed it all. 

"[Host will naturally know once host consumes it. All system can guarantee that it is completely safe.]"

Ace frowned a little, but since the system gave its words, he ought to believe it. He always does. So, taking a deep, calm breath, he solemnly commanded, "Proceed!"

The very next moment, Ace suddenly felt something icy injected directly into his heart before it started to course through his entire body, making him feel like nothing but ice. 

The next moment, Ace's widened eyes turned pitch black before the darkness started to spread on his skin. 

Right at this moment, out of nowhere, a dark blue cubic barrier appeared around Ace, and just as Ace was completely enshrouded in darkness, inky smoke rose from his body and filled the entire cube, but none of it was leaked. 

The chamber was deadly silent, and in its center was a three cubic meter corporeal dark blue cube that was filled with inky darkness, which appeared to be like an endless abyss. 

At this moment, the system's voice rang in Ace's blank mind. 

=====

[Host's soul has successfully entered the B.E.D]

[First Codex of Eternal Thief System has been successfully awakened!]

[System restart/upgrade required!]

[System restart/upgrade will start after the retrieval!]

=====

Ace has no idea about any of it; right now, all he can see is darkness and nothingness. Even though he didn't feel his body, he still felt icy and eerie as he was in the middle of endless emptiness without any clue what was happening.

Right at this moment, an ethereal voice rang, "You've finally come to me, Child of Darkness…" 

The voice was speaking in the language of Ancient Gods, and it was impossible to tell the gender. Furthermore, the voice was extremely gentle and gave Ace the feeling of warmth in that eerie darkness, but he still couldn't see or speak anything. 

"Let me have a good look at you…"The voice gently proclaimed. 

The very next moment thereafter, Ace found himself standing on an infinitely large dark platform while the surrounding was infinitely white. Ace, at this moment, was a completely dark figure in the hood, like his martial soul. 

Then Ace finally saw the only other thing except for black and white; it was a pitch-black throne, and its size was insurmountable, and Ace was like a speck of dust in front of it. Furthermore, despite feeling close, Ace, for some reason, knew he was too far away from that throne and would never be able to reach it. 

Furthermore, the throne was empty, and for some strange reason, Ace could feel strange closeness towards it and also indescribable loneliness that made his heartache. 

"You have grown so much. I've seen your birth, your suffering, your grief, your warmth, your love, your conviction, your resolve, your anger, your hatred, your joy… I've been seeing you from the moment your pitiful fate was decided." 

Ace started when he discovered that the gentle voice was coming from the throne itself! 

He tried to speak, "W-who are you?" 

"Child of Darkness, I'm your eternal fate, but I can be your enteral doom if you're not careful, just like your doomed brothers and sisters." The voice replied as it was filled with grief and pain. 

Ace had no idea what the voice meant, but he was feeling sadness unknowingly, which was a terrible feeling. 

Then he suddenly thought of something and exclaimed, "Are you the system?" This was the only explanation he could think of. 

"I am but a defeated throne. We don't have much time here since you were able to come here. Let me help you, for that is my purpose."The gentle voice replied.

Ace was extremely confused since he couldn't fathom just what that voice was trying to imply, and it clearly did not sound like the system. 

"What is this place, and how can you help me?" He asked for more information. 

"The former is not for you to learn yet, while the latter I can tell you. I'll construct the [1st Order of Darkness] into your soul. I just hope it won't return to me; instead, it will be you, Child of Darkness!"

Ace was startled. But suddenly, the next moment, he let loose a blood-curdling shrill before it vanished because his entire soul suddenly shredded into countless dark particles!

However, the next moment, unknown symbols from the throne started to fly toward those dark particles and started to interweave together!

Thus, the construction begins!
