Eternal Thief

Ace exits the shop in his devil disguise and walks toward Devil Mountain while stealing some devils' memories to understand what is going on clearly. 

He spotted many guards patrolling the city while the once blustering streets of the All Devil City were now almost barren. After he read a devil guard's memories, he couldn't help but click his tongue in amusement. 

'Myriad Thieving Fox? She's really enjoying this, isn't she?' Ace thought with a faint smile as he felt proud of Winter. 

Nonetheless, Ace didn't look for her because of the mission she was undergoing, nor did he need her. 

"Halt!" At this moment, a heavy voice stopped him in his tracks, and when he turned around, he saw an ash-pale devil guard walking over. His aura was quite fierce, and he looked at him with clear suspicions. 

However, Ace merely glanced at him and said one word, "Leave!" and then he started walking again.

The next moment, the guard's fierce expression turned blank, and he didn't stop Ace either. In fact, he slowly turned around and walked away. 

'Hmm, Soul Words have finally started to become useful.' A content smile appeared on Ace's face as he continued to walk toward the devil mountain as if he were on a stroll. 

In fact, he could've just entered stealth, but he didn't want to, and for some reason, he just wanted to walk without any stealth for some time. 

As the humongous triangular mountain got closer and closer, Ace found more and more guards in the area. But whoever tried to stop him he would leave after a single word. 

But when Ace finally senses the powerful presence of Law Awareness Realm cultivators close to the foothold of the mountain, he uses soul stealth instantly and vanishes without a trace. 

Ace could clearly see the red area ahead of him in the fate map, and the formations there were all at least low-grade-7. 

But he didn't even flinch because he had already gone through far more terrifying formations, and he used the space step talisman without hesitation. 

The next moment, he was on the other side of the blockade, and a hint of understanding appeared in his eyes, 'Just now, when I used the space step talisman, I felt connected to space… is it because of my space law? I even felt like my staggering law increased a little bit.' 

Previously, Ace didn't have a deep understanding of space, so he never felt like this before. But now, he could more clearly feel the space around him and its profound mysteries.

Nonetheless, Ace knew it wasn't the time to mull over it for long, and he started to head toward the mountain peak while using grade-8 stealth formation. 

This place was nowhere near the Sun and Moon Secret Realm level, nor did they have an inheritance like the Sun and Moon Sword Union. Ace didn't know how they could build these seals and keys, but he knew someone else was pulling the strings, and those three were mere puppets. 

Ace mused that the true mastermind behind all of this might show up once he breaks this mysterious seal. 

The journey towards the peak was without any hitch as the entire mountain was empty, and formations protected it. It was pretty clear that the Devil Ancestor didn't want anyone near this place while he was undergoing a breakthrough.

It was common knowledge that when someone was undergoing a breakthrough, they were at their most fragile state, and many cultivators with malicious intentions took advantage of this situation to get rid of high-level threats. 

Since the Devil Ancestor was an old monster who cherished his life and was willing to live like a leech, it wasn't surprising that he wouldn't trust even his subordinates. 

Furthermore, he had no idea that Ace had snuck here following them, and now they were all in immense danger while being utterly clueless about it. 

Following his fate map, he reached a particular location a few hundred meters away from the peak. 

Looking at the plain rock surface, Ace narrowed his eyes, 'There should be a trap door here… since this is a grade-7 formation…' 

A devious smile rose on his face, and the next moment, dismantle Qi gushed out from his hands and started to cover the ground where the hidden door should be. 

He was already a Grade-7 Heaven's Stealer Dismantler, and now he could dismantle anything below grade-8! 

Ace used his dismantle Qi, but not another else because he wasn't interested in dismantling and gathering the materials used in this door. He just wanted to turn this trap door into dust. 

If he weren't focused enough, anything he was dismantling would turn to dust, and it was a considerable disadvantage and an advantage in situations like this. He doesn't even have to bother to find the formation's weak spots or keys. He can destroy it. 

The next moment, the dismantle Qi started to corrode the mountain's surface, and the rocky surface suddenly turned into a dark yellow door, which was slowly getting consumed by the dismantle Qi.

When Ace deemed it enough, he stopped supplying the dismantle Qi, and the moment the dismantle Qi lost its connection with the gloves, it instantly vanished. The door crumbled like a sand castle, revealing a spacious staircase. 

Without hesitation, Ace took the staircase and headed downwards while he didn't forget to use another illusion formation to cover the opening. 

This entire passage was dyed in red, so Ace remained on high alert because he was now only a few hundred meters away from the dark orb. 

Ace found a sealed black gate shimmering with golden symbols at the end of the staircase, and the dark orb was behind it!

Furthermore, Ace suddenly feels a deep familiarity behind that door, as if a part of him was right behind it. It was pretty strange. 

'This is a high grade-7 formation… but so what!' Ace sneered before he used the dismantle Qi against it, and the luster of the gate started to vanish as dark dismantle Qi corroded it. 

At this moment, Ace stopped supplying the dismantle Qi, and the next moment, the gate turned into dust, and the moment the passage opened, thick dark mist gushed out!
