Zhang Menglong diligently labored in the nursery, collecting countless exotic flowers and herbs that had slept for ages into the Super God Academy, even taking the soil along.

It’s important to note that because of the passage of time, many exotic flowers and herbs had reached the end of their lifespan and withered away. As the saying goes, "fallen petals are not heartless things; they transform into spring mud to protect flowers." These plants had entered the soil, becoming nourishment for the medicinal herbs that grew afterward.

After batch upon batch of floral essence irrigating the soil, it was impossible to describe the land’s fertility. Even sowing an ordinary seed would sprout into a piece of spiritual medicine! Naturally, this soil became a priceless treasure—one that even Zhang Menglong’s Super God Academy’s medicinal fields could not compare to.

"I’ve struck it rich, struck it rich!" Zhang Menglong roughly counted his harvest this time, with at least hundreds of thousands of medicinal herbs, over ninety percent of which were divine grade with simply beautiful ages!

Generally, medicinal herbs are hoped to be older, but here, Zhang Menglong is afraid they’ll grow too old and wither away even if he planted for another two years!

"Really envious!" The martial artists outside the nursery showed an expression of envy as they watched Zhang Menglong’s figure.

A lingering odor surrounded Zhang Menglong’s feet outside the nursery. Though much thinner than before, they had seen the potency of that odor earlier, which couldn’t even be compared to poison mist, even managing to suffocate the very woods that emitted those toxic gases!

Moreover, even Han Xu, the universally acknowledged King of Poison, vomited for over thirty minutes after smelling it, and his face remains an iron blue. As for those martial artists who were knocked out by the stench, they’re still unconscious now, possibly dead.

So now, who dares to approach there?

Waiting for Zhang Menglong to come out and ambush him?

Isn’t that tantamount to seeking death?

To date, historical experiences have bloodily proven that provoking Zhang Menglong is absolutely a suicidal endeavor. If one can be friends with him, never become enemies. They almost shouldn’t dream of those medicinal herbs.

"Hope not to encounter this guy next time!"

Understanding this point, everyone—even if they felt unwilling—could only leave gradually.

[Dean, today’s harvest was impressive!]

"Indeed," Zhang Menglong replied with a smile, "With these medicinal herbs, I’ll find some time to refine elixirs, speeding up the enhancement of life levels significantly."

Gu Xiao’s body has now reached a Level Six spiritual body; Zhang Menglong’s own life level has reached Level Seven perfect life form. With these elixirs, he could break through to super life form in a short time, eventually finding a way to revive Gu Xiao.

...

"The energy around here is getting denser and denser."

Flying in the direction Gou Dan pointed, Zhang Menglong traveled for quite a while. In this place, a casual grab from Zhang Menglong condensed a third-grade divine crystal, indicating the energy concentration here had reached nearly ten thousand times that of the outside!

"At this point, even a pig could cultivate into immortality! Even if many people failed to join those superpowers this time, merely cultivating here for three months could recoup the value of the Heavenly Pride Order and travel expenses!"

"It’s unclear why people gave up on this treasure land back then," Zhang Menglong mused, feeling that the rumors might not be quite accurate.

Even if this place seems like a prison, its energy density is incomprehensible. When one improves sufficiently, they could leave anytime, right?

Alternatively, it could serve as a secret realm for cultivating disciples with powerful gifts.

In any case, leaving it neglected is unthinkably wasteful; without major brain hemorrhaging, one wouldn’t make such a decision.

The urgency in which those people left the Ancient Cave Heaven bannered some mysterious reason, and Zhang Menglong suspected that the Night Demons had intertwined with all these events.

[Dean, we’ve nearly reached the core area of the Ancient Cave Heaven. I’ll start narrowing the search range now, which should yield some findings. Since detailed exploration is needed, it might take some time.]

"Hmm, thank you." Zhang Menglong nodded, precisely during the refinement timing—processing the freshly harvested medicinal herbs into elixirs. Coupled with the dense energy here, there’s a chance he’ll breakthrough two minor levels in three months.

He took out several herbs that had developed spiritual intelligence, which began to complain noisily.

"Oh no, the Stinky Foot King is here again!"

"Stinky brat, let go of me!"

"Hey, hey, hey, why are you setting a fire?"

"The Stinky Foot King is killing...ginseng!"

...

The quality of these medicinal herbs was high, and despite some noise, the entire refining process went smoothly. Even higher-level elixirs didn’t attract tribulation thunder, as if this place was a blind spot for the world force, puzzling Zhang Menglong even further.

He casually tossed an elixir into his mouth, chewed a couple times, then swallowed it, "How about it, Gou Dan, did you discover anything?"

[Nearly everything in the surrounding area is scanned, with bountiful gains!]

Using holographic imaging, Gou Dan displayed the nearby terrain. Zhang Menglong was currently positioned in the southeastern direction of this region, and within a half-day’s journey, Gou Dan marked 27 points. Gou Dan believed these points had unique properties, likely signifying lands of inheritance.

However, the nearest location carried a black mark—the sole such marked spot.

"Gou Dan, what does this mark mean?" Zhang Menglong asked in confusion.

[Dean, this is the situation: the 27 locations all have high energy concentrations, resembling 27 peaks on a plain. But this black dot represents an energy-null area.]

"Explain in ways I can understand."

[That is, those 27 spots have extremely high energy concentrations, components likely formed artificially similar to formations, and could very well be the sites where ancient era powers settled down, offering potential gains.]

"I understand that, but what does an energy-null area mean?"

[It means there’s a vacuum energy zone there, seemingly deliberately concealed by someone. I suspect it might be even more unique than those 27 points, potentially tied to the history of the Ancient Cave Heaven. If we go explore it, we might find some surprises, but it could also be dangerous.]

"Alright, let’s first try one of those 27 spots," Zhang Menglong considered for a moment, "Each location likely shares common characteristics—checking one would give us insights. Then we can explore that energy-null spot. Can you find the location with the highest energy concentration among those 27?"

[Sure, it’s precisely at the center of this area.] Gou Dan immediately marked a red spot.

"Okay, let’s head there first!"
