A terrifying roar resounded, violently shaking the entire hall, a sound that seemed capable of collapsing the golden city.

Nie Yan looked towards the front of the hall and saw the mine slave Igrin in the distance had awakened. It slowly took a step forward, shaking off the stone dust covering its body. Each footstep caused the ground to tremble. A strange light flashed in its eyes, its gaze locked onto Nie Yan in the center of the hall.

"Damn human, you have trespassed into my territory!" the mine slave Igrin bellowed in Ancient Common Tongue.

The mine slave Igrin possessed a certain level of intelligence. These types of Bosses were the most difficult to deal with!

In a flash, its movements became fluid as it strode towards Nie Yan.

Nie Yan was startled by the awakening of the mine slave Igrin. He quickly commanded the four Demon Furnace Blacksmiths to block it, attempting to impede its advance.

Though the four Demon Furnace Blacksmiths were quite large, they were like children before the mine slave Igrin, their height only reaching Igrin’s chest. The mine slave Igrin swung its thick arms, wielding a scythe, towards the four Demon Furnace Blacksmiths. With a loud bang, the four Demon Furnace Blacksmiths were sent flying.

They staggered and fell to the ground, with damage numbers of seven to eight thousand floating above their heads. Such high attack power!

This kind of attack was enough to instantly kill any current Shield Warrior. No Shield Warrior currently had the defense and health to withstand the mine slave Igrin, let alone a Thief like Nie Yan.

The four Demon Furnace Blacksmiths struggled to their feet, attempting to block the mine slave Igrin, completely unaware that this was a suicidal action.

The mine slave Igrin took a large step and kicked one of the Demon Furnace Blacksmiths on the ground, sending it flying.

The Demon Furnace Blacksmiths were no match for the mine slave Igrin. Seeing the fierce demeanor of the mine slave Igrin, Nie Yan quickly summoned the Golden Land Dragon back and cast the Dark Dancer skill from the Shadow Walker's Cloak. His body slowly disappeared into the darkness.

The mine slave Igrin continued to hack and slash at the Demon Furnace Blacksmiths with its six enormous arms. After a short while, the four Demon Furnace Blacksmiths fell to the ground, turning into four corpses.

The mine slave Igrin looked around, but the hall was empty. Where was Nie Yan? It roared angrily and paced back and forth agitatedly, searching for Nie Yan.

At this moment, Nie Yan was about ten yards away from the mine slave Igrin. Seeing it walking this way, he quickly retreated.

He looked towards the front of the hall. On the wall at the front was a tightly shut golden door, which was the entrance to Igrin's Treasury.

Nie Yan carefully maintained a certain distance from the rampaging Igrin. After a while, Igrin suddenly made a move, walking towards Nie Yan's direction.

Nie Yan held his breath, shrinking into a dark corner, thinking about how to open the Treasury door without being discovered by Igrin. Discovering that the mine slave Igrin was coming over, he immediately became tense. If he were discovered by the mine slave Igrin now, his plan to open the Treasury would be completely ruined.

Watching the mine slave Igrin getting closer and closer, Nie Yan's heartstrings were stretched to the extreme. The Dark Dancer skill only greatly enhanced Nie Yan's concealment. It couldn't allow him to completely evade the mine slave Igrin's perception. If the mine slave Igrin's perception was high, and the level difference between them was so great, he would easily be discovered by the mine slave Igrin.

Nie Yan retreated to the corner of the hall until he had nowhere left to retreat. The distance between him and the mine slave Igrin was getting closer and closer, ten yards, eight yards, seven yards...

Nie Yan gripped a Random Teleport Scroll tightly. If he were discovered, he would randomly teleport away to escape.

According to his previous life's experience, once he teleported away, the Treasury key he had just obtained would become invalid. The mine slave Igrin would change the Treasury key and hide it in a new location.

Nie Yan could only take a gamble.

Seeing the mine slave Igrin getting closer and closer, Nie Yan gritted his teeth and swept to the side, passing not far from the mine slave Igrin.

The closest Nie Yan got to the mine slave Igrin was no more than five yards. This distance made his heart pound. Even during a PK battle, such a distance would easily be perceived, let alone against a Level 90 Lord!

Finally, the mine slave Igrin stopped about five yards from the corner of the wall. It looked around, its eyes still blank, and then walked towards another corner.

The mine slave Igrin patrolled to the other corner, stopping about five or six yards from the wall, and then walked in another direction. It turned out it was just on a routine patrol.

Nie Yan was somewhat surprised. Being approached to within nearly five yards of a Level 90 Lord without being discovered was truly an incredible thing. Nie Yan thought about it. This might be related to his extremely high concealment ability. Nie Yan's concealment stat was astonishing, even higher than Thieves at Level 80 or 90 in his previous life. In addition, the Dark Dancer skill provided a 300% bonus to concealment, making everything fall into place.

Now Nie Yan could confirm that as long as the distance between him and the mine slave Igrin was more than five yards, he would be safe and would not be discovered.

Relieved, Nie Yan walked towards the direction of the Treasury door.

The mine slave Igrin was still in a state of rampage, searching everywhere in the hall for Nie Yan's location. Nie Yan could easily approach the Treasury. He swiftly swept in front of the Treasury and examined the structure of the Treasury door.

This Treasury door was very peculiar. It was made of gold, but covered in cracks, as if made of many building blocks pieced together. In the middle was a keyhole, its size exactly matching the key in Nie Yan's hand.

Nie Yan looked back at the mine slave Igrin. The mine slave Igrin was patrolling back and forth, walking to a position quite far away from Nie Yan, about a hundred yards, with its back to him.

Nie Yan tentatively inserted the key into the keyhole of the Treasury door. He didn't expect that this would open Igrin's Treasury door. He just wanted to know how much time it would take to open the Treasury, so he could figure out a plan later.

Just as Nie Yan inserted the Treasury key into the keyhole, the keyhole swallowed the key, and the Treasury door slowly disassembled automatically, revealing a deep entrance, just about large enough for one person to enter.

The Treasury door continued to disassemble, and the entrance became larger and larger. At this time, the mine slave Igrin was startled by the noise. Seeing the Treasury door opening, it let out a sharp roar and pounced towards this side.

Nie Yan looked at the mine slave Igrin rapidly approaching him, and then at the ever-widening Treasury entrance. If he hesitated any longer, the mine slave Igrin would pounce on him, and that would be dangerous.

He didn't know if there were any unknown dangers inside the Treasury.

Never mind, Nie Yan gritted his teeth and charged into the Treasury.

The Treasury door was still very narrow, and the mine slave Igrin's huge body couldn't rush in. It roared repeatedly outside. Nie Yan quickly rushed towards the depths of the Treasury. He had to find the Aba Ke Destruction Cloak as quickly as possible. The mine slave Igrin was about to rush in!

Nie Yan took out the Holy Light Stone and placed it in his left hand. The Holy Light Stone emitted flickering light, guiding him into the distance.

The Aba Ke Destruction Cloak was nearby. The closer he got to the Aba Ke Destruction Cloak, the more Nie Yan could feel the surging energy transmitted from the Holy Light Stone.

Nie Yan checked the situation here. In the center of the Treasury was a corridor more than two hundred yards long, with stone chambers distributed on the sides. These stone chambers were filled with all kinds of valuable things, piles of gold coins and gems, which were very tempting. However, Nie Yan keenly felt that these gold coins and gems were emitting powerful dark auras.

Based on Nie Yan's keen sense of missions, he immediately thought that these gold coins and gems must not be touched.

There was a saying that greed was the original sin.

If other players opened the Treasury, disregarded the danger, and wanted to move these things away, they would not only fail to obtain wealth, but they might also lose their lives. Nie Yan watched piles and piles of gold coins and gems flash before his eyes. If it were his previous life, he might have gone crazy for this wealth, but in this life, Nie Yan had let go of many things.

Having been reborn, Nie Yan's state of mind was already different.

It was very foolish to risk one's life for money.

He didn't expect a windfall. His experience in his previous life was an inexhaustible treasure trove. He could earn much more money than here. Why should he jump into the trap set by the main brain for this money?

Under the guidance of the Holy Light Stone, Nie Yan reached a stone chamber at the end of the corridor. This stone chamber was about 5x5 yards in size. It was very empty, and a small treasure chest was placed in the corner.

The outside of this treasure chest was carved with some demon patterns, very exquisite, emitting red, blue, and green lights. The three-colored lights kept changing, sometimes brilliant and dazzling, sometimes dim and dull.

Seeing this treasure chest, Nie Yan's mood became extremely agitated. This was a sub-legendary chest!

He had only heard of sub-legendary chests, but he had never seen one. In his previous life, he heard that sub-legendary treasure chests would emit red, blue, and green lights, but that was just hearsay. He had some doubts about whether such a treasure chest existed, after all, he had never seen it with his own eyes. Seeing is believing.

He didn't expect that he would find a sub-legendary treasure chest here in this life!

Whether there was only the Destruction Cloak inside, or something else, he would have to open the treasure chest to find out.

Nie Yan squatted down and found that the treasure chest was locked. Fortunately, his lockpicking level was high enough. He had to hurry!
