While Night Demon was busy looking for a spirit gathering formation, Gu Ding and the others had already stepped into the entrance of the secret realm.

This arcane realm was formed from the corpse of a gigantic beast. That beast had not rotted into a pile of bones. Only a small part of its head was exposed on the ground, but it was already several hundred meters tall. The rest of its body was completely buried in sand.

At the entrance was a mouth that looked like it had been petrified. If Neptune had not pointed it out, Gu Ding and the others would have thought it was just an ordinary cave even if they were standing under the giant mouth.

Gu Ding and the others followed the entrance and walked down. If the giant beast was still alive, Gu Ding and the others would have been walking down its esophagus.

The esophagus was extremely deep, like a huge tunnel. Gu Ding and the others reached out to touch the ground under their feet. It did not feel like meat. Instead, it felt like hard rock, smooth and cold.

The group walked along the esophagus for more than two hours before they entered the abdominal cavity.

Looking around, the space that was supposed to be the stomach was so big that there was no end to it.

"This is a Meltdown Beast that the Martial Hunter Beasts keep. The Molten Beast was a very special kind of lifeform. It had an extremely strong defense and an independent stomach. Their stomachs could digest most items with energy fluctuations. Anything they swallowed would be completely melted into a kind of honey milk, which would then be secreted out of their nostrils. This honey milk contains extremely pure energy. It is the favorite food of the Martial Hunter Beasts. "

After listening to Neptune's explanation, Gu Ding and the others looked at the ground under their feet.

The ground here was completely different from the esophagus. It was milky white.

"The milky white stone under our feet, could it be …"

"That's right, it's the petrified honey milk." Neptune knew what Gu Ding was going to say and immediately gave the answer.

"It's already petrified. Is it still useful?" Lilliath was skeptical.

"Of course it's useful. Its stomach is an independent space. There is almost no energy escaping. Although the shape of this honey milk has changed, it will still have the same effect as long as it's processed. I'll teach Gu Ding how to process it. What you need to do now is to cut the petrified honey milk and put it into the Inventory. "

"However, because there are many living beings that died in this space, there are also some vengeful spirits hidden in this space. Elsa, you have to be careful. Don't leave their line of sight. "

Elsa frowned when she heard that. Ever since she entered the ruins, she had been restrained in all kinds of ways, and this feeling of not being able to use her strength was very depressing. However, she also knew that this was not the time to throw a tantrum. She held the giant ax with both hands and started digging less than twenty meters away from Gu Ding.

Gu Ding and the others picked up their own tools and started digging.

The 'ding ding' sound of metal hitting the ground reverberated into the distance. Some of the Wraiths that had been sleeping in the distance were quickly awakened. After identifying the source of the sound, they rushed toward Gu Ding and the others in a frenzy.

"Pay attention. Those wraiths have been awakened by you. They're quickly approaching," Neptune reminded everyone.

Gu Ding and the others slowed down their digging and diverted half of their attention to be on guard.

Not long after, ear-piercing screams echoed into Gu Ding and the others' ears. Soon, they finally saw the legendary Wraiths.

The so-called Wraiths were black mist-like creatures floating in the air. They came in different shapes. Some walked upright, some crawled on all fours, some even had multiple legs and some had wings … The only thing they had in common was that they seemed to be wearing strange masks on their faces. If one looked closely, one could actually see that although their masks were somewhat similar, there were still many subtle differences.

"Are these guys the Wraiths?"

It was the first time Gu Ding and the others had seen this kind of life form. They were a little curious, but they did not show the slightest fear.

Just as Gu Ding and the others were sizing up the creatures, a reptilian Wraiths suddenly moved. Its target was Elsa, who had the weakest soul strength. Obviously, they had a way to determine the strength of their opponent's soul.

Gu Ding raised his hand and shot a finger force toward the Vengeful Spirit. Unexpectedly, the finger force penetrated the Vengeful Spirit's body without causing the slightest bit of harm to the Vengeful Spirit.

"It's useless. You have to use a soul-type attack," Neptune reminded. "Or use Purple Thunderfire. Thunderfire has a dispelling effect on Wraiths, so it will be effective on Wraiths as well."

Hearing Neptune's reminder, Gu Ding's purple flame spewed out of his hand and swept toward the Wraiths. The Wraiths suddenly let out a shrill scream that was extremely ear-piercing.

A moment later, the Wraiths' mask that had attacked Elsa disintegrated and turned into a black mist that dissipated.

The remaining Wraiths seemed to have been agitated by the scream. They changed their previous attitude of watching and rushed toward Gu Ding and the others in a frenzy.

Gu Ding stood in front of Elsa. Purple Thunderfire spewed out of his palm and formed a giant flame python that intercepted all the attacks that rushed toward Elsa.

On the other hand, Liliath's Soul Power had mostly recovered after being replenished with Soul Potions and a few hours of traveling. Hellfire, which was dominated by Soul Power, gushed out like a black torrent, surging in all directions.

Dockett covered the surface of the flying daggers with a layer of soul power. Hundreds of flying daggers spewed out and shot out beams of silver light in the large space.

Hundreds of wraiths screamed in agony. Dozens of them fled while the rest were killed by Gu Ding and the others and turned into nothingness.

Looking at the fleeing Wraiths, Liliath chased after them. She had just felt that her Hellfire was devouring these Wraiths and feeding them back to her soul. As a result, not only did she not consume any of her soul power during the ten-minute battle, but she had also recovered all of her soul power.

Seeing Liliath chasing after them, Gu Ding was about to stop her when Neptune called out to her.

"Let her go. There's no danger over there. Instead, there are great opportunities."

Liliath chased all the way and found that the twenty or so fleeing Wraiths had fled to the top of a statue and stopped running. Instead, they hovered and roared threateningly at Liliath.

Lilliath glanced at the statue. It looked like some kind of beast. Although she was a little curious as to why there was a statue in this space, she did not think too much about it. Black Purgatory immediately spewed out and engulfed the twenty or so Wraiths.

In just a moment, all the Wraiths were absorbed by Purgatory. Liliath felt that her soul seemed to be slightly stronger. Only then did her gaze fall on the statue.

"This thing in front of you is the Spirit Crystal of this Molten Beast. A beast's spirit is the same as a human's soul. This Molten Beast probably placed its spirit here to devour the souls of the dead to make its spirit stronger. However, when its consciousness died, its spirit was probably still in this space. That's why the spirit without consciousness has been trapped in this space. As time passed, it turned into a crystal. "

"You can put it away first. After you've become a deity, you can find time to use Purgatory to slowly melt it down. This Molten Beast's cultivation level is almost comparable to a True God. This spirit crystal will be of great benefit to you, but with your current soul strength, you won't be able to absorb it. "

"This spirit crystal can only be used by one person. However, other than that, the crystal in the Molten Beast's brain is very nourishing for everyone's soul. Once we've collected all the honey milk, we'll go to the brain. "

Liliath nodded and put the spirit crystal into her Inventory. Then, she ran toward where Gu Ding and the others were. After returning to the original excavation site, Liliath smiled. "Besides killing those Wraiths, we also obtained the spirit crystal of this Molten Beast. It's a big harvest."

"It's good stuff indeed. Logically speaking, this guy's soul should have dissipated long ago after such a long time. It's probably because this independent, sealed space allowed its soul to survive." Gu Ding felt that this was an unexpected gain.

"Now that there's nothing to disturb us, let's dig with all our might. This space is so big, I don't know how long it'll take to finish digging." Ayesha looked up at her surroundings. She felt that it would take at least twenty to thirty days for the honey milk to be mined.

"Gu Ding, I remember that you left behind a few sets of multifunctional robots that Robert gave you, right?" Neptune suddenly remembered. However, Gu Ding had placed the items in Robert's Inventory, so Neptune could not see them.

Gu Ding slapped his head. "I did. How could I have forgotten about that? Originally, it was to prevent digging and the like, but this isn't land, so I forgot about it. However, looking at the hardness of these honey milk stones, it's not much different from ordinary soil. It should be usable. "

As Gu Ding spoke, he took out five small multifunctional robots and set up the digging function.

After the five arm-length robots detected the hardness of the ground, they quickly began to dig.

In a few seconds, hundreds of tons of honey milk were dug out. Their efficiency was a hundred times faster than Gu Ding and the others.

Gu Ding and the others followed behind the robots and put the honey milk into the Inventory.

More than three hours later, when Phaser and Miko appeared at the entrance of the stomach, Gu Ding and the others were already finishing up their work. The ground level in the stomach was nearly a hundred meters lower than it was before.

Seeing that Phaser and the others had returned, Gu Ding and the others waved at them, and the two immediately jumped down.

"Looks like Night Charm fell for it?" Gu Ding asked the two of them with a grin.
