After a cascade of hundreds of data prompts, the display showed that the first challenge task was completed.
[Challenge Task 1 Completed: Killed 100 Abyss Demons.]
This was immediately followed by prompts for leveling up twice.
[Source Energy Level increased to Level 7, All Attributes +1, Agility Attribute additionally +0.3]
[Source Energy Level increased to Level 8, All Attributes +1, Agility Attribute additionally +0.3]
However.
Spirit noticed that there was no data prompt showing the completion of challenge task 3.
Challenge Task 3 was to kill the Horned Demon Commander.
The absence of a completion prompt for Challenge Task 3 indicated that...
At the same time.
The large spatial machinery of Quenching Castle operated at maximum power, beginning to detach from the Abyss World.
The very next second after Quenching Castle detached from the Abyss World, the nearby space underwent drastic changes.
Dark clouds in the sky gathered, condensing into an angry face of the Abyss Demon King.
In an instant, the colors of the sky and earth changed, the ground shook, and the mountains quivered.
"Quick, return!" Lu Heng shouted hastily.
Almost simultaneously as he shouted, a series of data prompts appeared.
[Suffered from Spiritual Pollution by an unknown existence, Spiritual Attribute -1]
[Suffered from Spiritual Pollution by an unknown existence, Spiritual Attribute -1]
...
In the blink of an eye, his Spiritual Attribute had dropped significantly.
And at this moment.
A loud "bang" erupted from the ruins of the building, and the Horned Demon Commander blasted the rocks away, emerging from the rubble and letting out a furious roar into the sky.
Lu Heng saw Su Muyu vanish on the spot and immediately chose to return.
Just before his spiritual power was about to hit rock bottom, his field of vision darkened.
The Spiritual Pollution prompts finally ceased, followed by the appearance of a completion prompt for the Abyss Battlefield.
[Abyss Battlefield ended, returning to the main world...]
[Main Quest 1 Completed: Opened the iron cage, escaped from the Horned Demon Commander's Hunting Ground. Reward: 100 points of Divine Energy.]
[Main Quest 2 Completed: Survived 3 days in the wasteland city. Reward: 100 points of Divine Energy.]
[Main Quest 3 Completed: Maintained sanity before time ended. Reward: 100 points of Divine Energy.]
[Challenge Task 1 Completed: Killed 100 Abyss Demons. Reward: 300 points of Divine Energy.]
[Challenge Task 2 Completed: Found the castle hidden in the wasteland city. Reward: 300 points of Divine Energy.]
The next second.
When Lu Heng opened his eyes, he found himself back in the room at the express hotel, sitting face to face with Su Muyu.
The clock on the wall had just struck 12:00:01 a.m., and the date was September 12.
As known, while they spent 3 days in the Abyss Battlefield, upon returning to the main world, the time was the same as when they entered.
Huff, huff, huff…
It was Su Muyu's first experience with the Abyss Battlefield, and she had just suffered continuous Spiritual Pollution, so upon returning, she was taking deep breaths.
"Are you okay?" Lu Heng asked.
Su Muyu's lips pursed as she hugged her knees, resting her head in Lu Heng's arms like a gacha egg, soothing her tumultuous emotions.
After a while, she lifted her head, feeling that something was amiss, and quickly lifted her right hand to shake it, exclaiming, "My Crystal Bracelet is gone!"
This Energy Crystal Bracelet was a reward for completing a series of hidden tasks, the added attributes were of great help to her, and its sudden disappearance threw her into a panic.
Lu Heng reminded, "Take a look at the item column on the data panel."
Su Muyu quickly checked the data panel, then saw an [Energy Crystal Bracelet] listed in the item column.
"Hey... there's a bracelet in the item column."
"This Crystal Bracelet belongs to the Abyss World and cannot be brought back to the real world before undergoing Law Integration. It's the same reason why weapons and equipment from the real world cannot be taken into the Abyss World," Lu Heng explained the reason.
Since Blue Star and the Abyss World are two different worlds, their fundamental World Laws are entirely different.
The laws of physics from Blue Star are not applicable in the Abyss World.
For example, the absolute zero on Blue Star is minus 273.15 degrees, the boiling point of water is 100 degrees, and the cosmic microwave background temperature is 2.7K, but this may not be the case in the Abyss World.
Because the World Laws are different, items from both worlds cannot freely move between them.
Of course, it is not completely impossible to carry items across the two worlds, but the items first need to undergo law assimilation.
It's not just Su Muyu's Energy Crystal Bracelet; Lu Heng's Aurora Blade was the same—it was stored in the item column but couldn't be taken out.
"So, I can't use this bracelet anymore?" Su Muyu frowned.
"You can take it out again the next time you enter the Abyss World. If you want to use this bracelet on Blue Star, you'll need to perform the Law Integration," Lu Heng continued to explain.
"How is the integration done?"
"You integrate it with Divine Energy. You can give it a try."
"Alright, I'll give it a try." Su Muyu attempted to retrieve the Energy Crystal Bracelet. A prompt appeared, stating that using Divine Energy was required to perform the integration: "It will cost 300 Divine Energy to retrieve. Should I take it out?"
"Take it out. The Divine Energy we obtained from this round at the Abyss Battlefield should be sufficient," Lu Heng nodded in agreement.
Su Muyu chose to perform the Law Integration and successfully retrieved the Energy Crystal Bracelet, put it on her wrist, and shook it, "Does it look good?"
Girls will be girls, putting on equipment without first asking if it's powerful, but rather if it looks good.
Lu Heng shook his head and smiled, then looked at the integration cost for the Aurora Blade. As expected, it was more expensive than Su Muyu's bracelet, requiring 600 Divine Energy to complete World Law Integration.
After all, the Item Level of the Energy Crystal Bracelet was D-Level, and the Aurora Blade was C-Level.
The hardness and Attack Power of the Aurora Blade were at the top of the C-Level weapons, and combined with the In-depth Level Seven Styles, it could decapitate demons of the same level with a single strike.
In this round at the Abyss Battlefield, they completed three Main Quests and two Challenge Tasks, obtaining a total of 900 Divine Energy, a pretty good haul.
So, Lu Heng chose to use 600 Divine Energy to perform the basic Law Integration, and then drew the Aurora Blade from the item column.
An advantage of items that undergo World Law Integration is that they can be stored in the item column, effectively having an invisible storage space.
With a thought, Su Muyu asked, "Since items from the Abyss World can be integrated, can the real world's items also be taken into the Abyss World after integration?"
Lu Heng smiled and nodded, "You're learning to extrapolate, yes, indeed they can."
Su Muyu continued to ponder, "Then is it possible to bring guns into the Abyss World?"
"Yes, and most Superpower Users share your sentiment," Lu Heng smiled.
"Firearms are indeed powerful. Wouldn't most people think that?" Su Muyu furrowed her brow, catching on that Lu Heng didn't seem very optimistic about firearms.
It wasn't that Lu Heng thought firearms were lousy; there was another reason: "Indeed, after one or two rounds in the Abyss Battlefield, the number of people bringing firearms will increase."
"Then those with guns would be very powerful, right?" Su Muyu suddenly felt that saving her Divine Energy to bring a gun to the Abyss World was a good idea.
"Firearms are indeed useful in the early stages, but there's one characteristic of firearms—they don't benefit from Strength enhancements. Unlike melee weapons, where the more Strength you have, the more powerful your attacks become…"
Lu Heng paused briefly then continued, "It's true that spending Divine Energy on firearms in the early stages has good effects, but in the mid to late stages, if your Skills, Talents, and firearms aren't related, the advantage disappears.
"And because you spent the Divine Energy on firearms, your own growth is too slow, which turns it into a disadvantage."
Su Muyu listened attentively, pondered, and slowly nodded, "So it means improving myself is most important, and if I want to upgrade my weapons and equipment, it should be related to my abilities."
"That's correct." Thinking of someone, Lu Heng added, "And sometimes, having bullets on you is not a good thing. Like running into that Chen Zihang…"
At the mention of this, Su Muyu's eyes widened in surprise, "That's true…"
Chen Zihang's ability was of the Metal Element, meaning he could snap his fingers, and all bullets within a certain range would automatically fire.
If the opponent had a lot of bullets on them, they might end up peppered with holes.
In fact, at the beginning of Abyss Descent, Superpower Users using firearms had decisive dominion. Only after the Class system emerged did the overwhelming force of firearms become less pronounced.
Of course, if a Superpower User possesses firearm enhancement Talents or Skills, they won't be at a disadvantage later on.
