Looking at the empty space in front of him, Gu Ding guessed that he had been transported to the twenty-first floor. According to his previous experience, the sixteenth floor should be similar to the previous floors. However, the environment in front of him had no gravel, weeds, or dead trees. There was only a gray stone floor.

"We're in luck!" Neptune quickly confirmed Gu Ding's guess. "This is the twenty-first floor."

"How do we go?" Gu Ding looked around and felt that any direction seemed to be the same.

"I don't know," Neptune gave a strange answer. Neptune gave a strange answer. "Before we arrived at this layer, the result of the exploration was like a cloud of fog. We could faintly see something glowing in the middle of the fog. However, now that I've entered it, it's like entering a fog. I can only see white all around me. If it weren't for your eyes, I wouldn't even be able to explore this floor. There must be some special rules here that can avoid my coveting and exploration. "

"There are no secrets in any of the other places in this ruin except for this area. Therefore, Helen's inheritance can only be hidden on this floor. It can't be hidden anywhere else." Neptune gave his own speculation.

"Then I'll choose a direction at random!" Gu Ding turned around again and found that any direction was the same. This place made it hard to tell north, south, east, and west. He had no choice but to choose a direction at random and run.

The day passed quickly. Along the way, Gu Ding did not see anything other than the gray stone floor.

"Neptune, did you find anything unusual along the way?" Gu Ding could not help but ask.

"My exploration is useless, but I've been using your eyes to observe the surroundings. I didn't find anything unusual. I just found that every gray stone brick on this floor is exactly the same. Their shape, size, color, and even the size of the gap between two bricks are exactly the same," Neptune told him the results of his exploration. "It feels like I'm walking in an illusory array …"

"Wait, an illusory array … This is probably an illusory array. It's because an illusory array is useless to you that you can't see the gray stone floor. It's very likely that the fog you see is the real scene on this floor, "Gu Ding said and stopped in his tracks.

"But I can't detect any signs of an array." Neptune voiced his doubts.

"I can't find anything. Maybe it's because your clearance isn't high enough." "Tell me, which direction in the fog am I in right now, and how do I get to the center of the fog?" Gu Ding gave his own guess.

"You've always been in the center. No matter how you move, the mist seems to move with you." Neptune had noticed from the beginning that Gu Ding was teleported to the center of the mist.

"I understand!" Gu Ding immediately stopped and sat down cross-legged.

"What do you understand?" Neptune was confused.

"I only have a guess. Time will tell us if I'm right or wrong." Gu Ding did not say what he understood. Instead, he sat cross-legged on the ground and took out the one-star monster carcasses that were piled up like a mountain. He used the devouring flame to engulf the carcasses and began to refine them.

Seeing that Gu Ding had gone straight into cultivation mode, Neptune did not ask any more questions. What he did not understand was why he could not figure out what Gu Ding had figured out, even though he was much smarter than Gu Ding. However, he kept an eye on his surroundings, as well as Liliath and the others' movements.

Time passed, and the day of the site's closure drew closer. Gu Ding sat where he was and refined the monster carcasses. The vitality energy kept pouring in.

Gu Ding sat where he was and cultivated for three days and three nights. He refined tens of millions of monster carcasses, but the effect of Emperor Body of Nature only increased from 3,000 times to 3,100 times.

On this day, Neptune finally noticed that the fog within his detection range was slowly thinning. He quickly notified Gu Ding. "Gu Ding, the fog seems to be slowly thinning."

Gu Ding opened his eyes and put away the monster carcasses that were piled up beside him. However, he still sat cross-legged and waited patiently.

Under the Sea King's probing, the fog finally dissipated completely. He finally found a palace not far away.

At this time, a golden palace suddenly appeared in front of Gu Ding. The steps of the palace were less than fifty meters away from where he was sitting cross-legged.

Only then did Gu Ding stand up. He finally knew that his guess was right.

"What did you find?" Neptune could not help but ask.

"If you were the one who set up this site and you wanted to hide a treasure in the maze, where would you hide the treasure in the maze?" Gu Ding asked.

"Of course it would be hidden in the deepest part of the maze! That's because the deeper you go, the less likely it is for outsiders to escape the maze, and the less likely it is for them to get the treasure, "Neptune gave his answer. The Sea Emperor gave his answer, and he quickly understood. "I understand now. If the area covered by this fog is like a maze, then the center of the fog is the deepest part of the maze, so the treasure is hidden in the center of the fog!"

"Because the treasure is in the center of the fog, and the place I was teleported to was also in the center of the fog. That means the treasure has always been in my hand. Moreover, no matter how I moved, the center of the fog kept changing. This means that the position of the treasure and I are actually in the position of a person and a shadow. There's no need to waste energy chasing my own shadow. So, I chose to wait. "Gu Ding gave his answer.

"Now that the palace has appeared, let's go in and take a look!" Neptune also looked a little excited. Although he could detect the existence of the palace, he still had no idea what was inside. His detection was blocked by a strange rule outside the palace, and he could not detect anything inside.

Gu Ding also stepped up the steps of the palace and walked toward the main hall.

Above the main hall's main door, there was a golden plaque with the words "Demon Suppression" clearly written on it.

When Gu Ding reached the door, the door creaked open automatically before he could reach out to push it.

Gu Ding was stunned for a moment, but he immediately stepped through the door.

As soon as he stepped through the door, a beam of light shot toward him. Gu Ding quickly dodged, but he could not avoid it. After being hit by the beam, Gu Ding did not feel anything unusual. "What's going on?"

Suddenly, a mechanical female voice was heard.

Gu Ding did not expect that a beam of light would sweep over him, and his details would be revealed. Generally speaking, only an intelligent wristwatch that had acknowledged its owner could detect one's physical data. Other methods would not work. Therefore, the other party's detection made Gu Ding a little annoyed.

"Hello, young man. It was just a routine detection. I didn't mean to offend you." A woman stepped out of the darkness. She was dressed in red armor and had a slender figure.

Gu Ding was shocked. He did not notice that there was someone else in the main hall from the beginning. Moreover, he still could not detect the other party's presence after she walked out.

"I can't detect her presence!" Neptune suddenly felt a little uneasy. It was the first time he encountered a situation where he could clearly see the other party standing there, but he could not detect anyone.

"It's normal that you can't detect my presence because I'm just a projection." The woman continued to walk toward Gu Ding.

Gu Ding finally saw her clearly. She was a beautiful short-haired woman with a heroic air. After looking her up and down, he suddenly felt that she looked familiar.

"She's Helen!" Neptune recognized her immediately.

"My name is Helen. You should have heard of me before entering the ruins." The woman introduced herself in a free and easy manner. "I fell more than two hundred thousand years ago. This is just a projection. The one who is talking to you is a fragment of my consciousness."

"Hello, my name is Gu Ding." Gu Ding was slightly relieved. "What is this place?"

"This is the Ancient Demon Temple, a place where demon-suppressing powerhouses are trained," Helen explained.

"Although the Demon Tribe and humans are no longer allies, there's no need to suppress them. The biggest enemy of humans now should be the Bug Tribe. "Gu Ding did not understand.

"The demons we're talking about are different from what you're talking about. You're talking about the local Demon Tribe, but the demons I'm talking about are invaders from other dimensions. Invaders from other dimensions, no matter what race they are, can be called demons. For example, the Bug Tribe, the Abyssal Tribe, the Nether Tribe, the Protoss … and many other races. Helen explained very seriously, "These invaders from other planes are the enemies of all of us humans. The Demon Temple is also trained to fight against these fellows. "

"In other words, the main mission is still to kill the Bug Tribe?" Gu Ding roughly understood what she meant.

"The Bug Tribe is powerful now. You can think of it that way." Helen nodded.

"I don't quite understand. Do you mean that I need to join this organization called Demon Temple?" Gu Ding asked with a slight frown. He did not want to join any organization. This was the main reason why he chose to become an Interstellar Pirate.

"Demon Temple is not an organization. It's actually just a special heritage palace with teleportation and reward functions. Only those who are recognized can get the key to this palace and gain the right to enter this palace. In this palace, you can accept the corresponding challenges and obtain rewards to improve your strength. In short, it's a platform that allows you to obtain more high-quality cultivation resources. "

"When I was alive, the reason I was able to become the strongest person in the shallow sea region and kill the Galactic Beast with the strength of a Higher Deity was because I've always obtained the best cultivation resources from Demon Temple, far surpassing the other powerhouses in the shallow sea region."

Helen said as she took out a golden key. "There are a total of nine keys to Demon Temple, and they're in the hands of nine different people. This is one of them. Most of my wealth is stored in the warehouse of Demon Temple, and this key is needed to open the warehouse. There are also my memories and inheritance, as well as the inheritance and memories of the powerhouses who have used this key before me. I'm giving it to you now. From now on, you're the owner of this key. "
