[Dean, the number of those Night Demons is increasing, now within my sensing range, the number has exceeded 200,000, and more than 90% of them are at Life Forms level above Divine Cultivator!]

"How can there be so many?" Zhang Menglong’s scalp tingled upon hearing this magnitude.

If it were the normal Night Demons, he carried a transformation device for Ultraman with him, just by emitting light, the Night Demons would perish no matter how many came; even if it’s 2 million, 200 million, or 20 billion, there’s nothing to fear.

But now it’s obviously daytime, yet the Night Demons can still operate normally. Given their indestructible nature, even if Zhang Menglong exerted all his strength, dealing with just dozens or hundreds would be his limit; there’s simply no way to protect himself against a siege of 200,000 Night Demons.

Of course, he could use the power of the Super God Academy teachers, but those indestructible beings, even for the teachers of Super God Academy, at most they could help Zhang Menglong carve a bloody path, whereas now Zhang Menglong wants to explore this area thoroughly and uncover its hidden secrets.

He has just arrived here, hasn’t even studied the area carefully, letting him leave now is really unsatisfying.

[Dean, I sense that these Night Demons seem to be coming with an intent, perhaps there’s some force manipulating them to gather here.]

"Oh? Is there such a thing?" Zhang Menglong seemed to find some key insights, "Could it be that I have entered some special place? Is something attracting them here?"

[Dean, it’s not something attracting them, but something guiding them.]

"Guiding? Is it human-made?"

[Exactly, I’ve sensed an extremely strong energy in the vicinity of this area. This energy is somewhat similar to Soul Power and spiritual power, but slightly different from those, its radiation range coincides with the gathering radius of those Night Demons, it seems under this force’s drive, the Night Demons are coming in droves.]

"Looks like someone wants to harm me," Zhang Menglong looked around, though it was empty all around, Gou Dan told Zhang Menglong that even though he is surrounded now, the nearest Night Demons would take about 10 minutes to reach him.

[Dean, should we leave here first and think long-term?]

"No," Zhang Menglong shook his head, "We’ve come this far; we can’t just give up halfway. I have to uncover the secrets of this Ancient Cave Heaven."

[How do you plan to proceed?]

"Can you locate the source of that force?"

[Give me a minute, the master of this spiritual power has done some tricks in manipulation, for normal people there seem to be tens of thousands of sources, but if I tweak it a bit, I should find the correct location.]

Gou Dan immediately began precise calculations. This complex calculation method and process would challenge even the world’s most powerful Artificial Intelligence.

"Done!" In less than a minute, Gou Dan completed the precise calculation.

[Dean, underground at this position, there should be something there!]

"It’s not far from me!" Zhang Menglong immediately flew towards the location calculated by Gou Dan, in this direction, the nearest Night Demons would likely make contact with Zhang Menglong in less than three minutes.

"Here!" Zhang Menglong took barely 30 seconds to locate the position found by Gou Dan, but it was still a vast, barren wasteland, with nothing in sight.

[Underneath!]

"Got it!"

Zhang Menglong directly pulled out a high-end excavator, starting to dig underground.

"Sure enough, at an underground depth of nearly 20,000 meters, a massive underground space appeared here, this space is even two to three times larger than the empty cavity at Sword God Manor.

As the excavator’s anti-gravity system gradually shut down, it settled firmly in this space, with nothing here except a structure resembling a Bell Tower.

This building is about 15 meters tall, entirely blood-red, looking more like a tombstone.

[Dean, this is the source of the energy summoning those Night Demons, and it’s also the core position of this energy void region!]

"Looks like there’s definitely a haunting here," Zhang Menglong walked toward that tombstone.

"Kid, if I were you, I’d suggest leaving here quickly, this isn’t a place you should be!" At this moment, a sinister voice emitted from the tombstone.

A semi-transparent blood-colored phantom emerged from the tombstone, blocking Zhang Menglong’s way.

"Oh? There really is a ghost?" Zhang Menglong looked at the translucent phantom, "I didn’t expect a Soul Body hidden here, quite interesting. Did you bring those Night Demons here?"

"Night Demons?" The phantom paused, "Is that the name you gave my treasures?"

"Your treasures?" Zhang Menglong noticed these words, judging by his tone, those Night Demons are indeed related to him, seems he came to the right place, "Did you create those Night Demons?"

"Kid, knowing too much isn’t a good thing," the phantom said, "Since you’ve found this place, to prevent unnecessary troubles, I’ll have to keep you here."

"So it was you!" The Night Demons are very close to Zhang Menglong now; he can even sense their presence.

These Night Demons are significantly different from those Zhang Menglong encountered before; they not only fearless the sunlight, Zhang Menglong even feels a completely different life aura from them.

This feeling is difficult to describe; if judged by Life Levels, most of these Night Demons are at the Super Life Form level, but they still differ somewhat from the Super Life Forms known to Zhang Menglong, as if they’re one level higher, yet tens of thousands of miles from Ultimate Lifeform.

This feeling is like that of a semi-finished product of a higher life.

"Since you can control those Night Demons to come here, shouldn’t you be able to make them leave too?" Zhang Menglong smiled, "Why don’t you have your minions step back first?"

"Hahaha, I haven’t seen a living person for so long, didn’t expect such an arrogant kid. You’re now surrounded by my Blood Demons, what right do you have to negotiate with me?"

"Hehe," Zhang Menglong smirked, "Let me guess why you’re so eager to drive me away, it must be you’re afraid I’ll discover something."

"Why don’t you handle it yourself and instead use those Night Demons?"

"It shows you’re currently very weak, unable to deal with me yourself."

As soon as Zhang Menglong finished these sentences, the Soul Body’s expression became extremely grim.

"I seem to feel something beneath the tower, what could it be?"

"Oh, it’s a corpse, whose could it be? This thing wouldn’t be your grave, right? I’m quite curious, should I dig it up to check?"
