[Dean, I just did a test. The energy concentration in this place is about 1083 times that of the outside world, and there are many elements that do not exist in the external world. It is truly a geomantic treasure land.]

"That intense?" Zhang Menglong hurried along, even though he was flying quickly, he did not feel the consumption of energy in his body at all. With just a slight use, as long as he took a breath, he could almost immediately recover.

[From this place, I sense an aura similar to that of the Heavenly Prides list. This place seems to have some connection with the list, or perhaps the list is the entrance to this Ancient Cave Heaven.]

"It seems that this place is worth studying. We have one month of time, right?"

[This one month is external time. The time flow rate in this Ancient Cave Heaven is not synchronized with the outside world, with a difference of about several dozen times. You will need to spend roughly 3 years here.]

"Damn, why is it so long again?" Zhang Menglong rolled his eyes, "But the time is more than enough, and it allows me to explore more. If I can find some good things, it would be well worth it."

[Dean, let's go in that direction.]

Gou Dan pointed out a direction for Zhang Menglong. This Ancient Cave Heaven was indeed too vast, and finding a place with treasures in such a huge space was not an easy task, even for Gou Dan.

It had to narrow down the range first, then conduct precise searches within a certain area.

[The energy throughout the space is gradually increasing in that direction. I think that direction is likely the origin of this Ancient Cave Heaven.]

"Oh, there's a warcraft!" Zhang Menglong saw a huge creature slowly moving in the distance. Its height was about 8 meters, but its life level was not very high, probably only the degree of Divine Breath fifth or sixth-grade.

This level of warcraft poses almost no threat to those Heavenly Prides.

Such warcraft held little interest for Zhang Menglong, who just casually passed by it and headed towards a dense forest ahead.

"Hmm?" Zhang Menglong suddenly noticed a group of creatures resembling tigers and wolves rushing toward the forest, seemingly afraid of something.

"What is happening?" Zhang Menglong looked in the direction they were fleeing but saw nothing pursuing them. Moreover, there were hundreds of warcrafts, close to Divine Cultivator-level life forms. What could make them so afraid?

[Dean, it seems because the black night has arrived.]

"Ah?" Zhang Menglong gazed at the distant horizon and observed a Twilight Line moving in this direction.

This made Zhang Menglong even more puzzled. Night is known to be a warcraft paradise. By their habits, they usually hide during the day and come out at night. He had heard of warcraft fearing sunlight, but never fearing the night.

"What is going on?"

More strange things happened; the Twilight Line moved halfway and then went back, like time suddenly reversing.

Not only that, he carefully observed that the movement direction was not entirely the same but had a certain angle, as if under a constant light source, this world continued to move non-routinely.

"This place has some problems!" Zhang Menglong suddenly stopped and pondered. This world's phenomena instinctively reminded him of Liu's Three-Body world, a world where you never know if the sun will rise tomorrow.

Of course, even if he were truly in the so-called Three-Body world, Zhang Menglong would not be afraid. His body strength wouldn't be greatly affected even if he rushed into a black hole. High and low temperatures were not scary to him.

But for some reason, Zhang Menglong vaguely felt that entering the black night would lead to some dangerous events. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

Beasts' instincts are often very accurate; the Twilight Line lingered at its original position several times before finally surging towards where Zhang Menglong was, covering everything in darkness within seconds.

This world had no other light sources, and once plunged into darkness, even Zhang Menglong was completely lost.

"It's so weird, my night vision abilities are useless." Zhang Menglong's eyes were far more powerful than any advanced night vision device, but in this darkness, he was nearly blind, as if something in the night swallowed the light.

"Roar!"

A beast's wail came from the forest, followed by chaotic sounds as if many warcraft were frantically charging around the forest.

[Dean, something is slaughtering that group of warcraft!]

"Is it another warcraft?" Zhang Menglong asked.

[I don't know what it is, but those things' life structures are very similar to those of humans.]

"Humans? There are humans here?" Zhang Menglong was surprised, as according to what he knew, there should be no living humans in this Ancient Cave Heaven.

And even if there were, why would they slaughter warcraft in such a terrifying night?

"Hold on!" Zhang Menglong suddenly recalled something.

Those warcraft weren't afraid of the night! They feared these Slaughterers appearing in the night!

Suddenly, Zhang Menglong felt chills down his spine. What were those things slaughtering the warcraft?

[Dean, life forms are approaching!]

"I feel it!" Without Gou Dan's reminder, he felt the life forms closing in on him.

"So fast!"

These things approaching were incredibly swift, even surpassing the speed of ordinary First-grade Divine Cultivators, with a speed leaving 99.9% of Heavenly Prides in the dust.

"Ultra Instinct!"

Zhang Menglong completely couldn't see the creature, couldn't even sense its presence, relying solely on an instinct for avoiding danger to evade its pursuit.

He only felt a cold sensation on his neck, just a slight delay, and his head would be immediately chopped off.

For Martial Artists, they don't need to use their eyes to determine their surroundings; their divine perception acts like a radar, detecting everything around.

But this ability was completely ineffective on this eerie creature, just like a stealth fighter absorbing radar waves, Zhang Menglong's divine perception felt only a void.

He activated the lighting system on his wrist, but weirdly, the ordinary light seemed to be swallowed by the darkness, giving him no visibility.

"Sharingan!"

"...Can't see?"

"Rinnegan... Byakugan... Eyes of Golden Flame!"

Zhang Menglong tried several pupil skills, yet none helped him see anything. Though they had some effect, it felt like being in a cinema, seeing just faint outlines, which were indeed human outlines.

With two flames appearing in Zhang Menglong's eyes, "You're forcing me to play with fire again, huh..."
