Urban Divine Doctor Descends the Mountain

On the other side, under the guidance of the Sovereign Witch, Lin Dong arrived at the edge of a cliff.

This cliff was very special. Above it, a waterfall cascaded down.

The waterfall was grand, just like those depicted in the poems of the celestial poet.

A torrent plunges three thousand feet straight down, one wonders if the Milky Way falls from the ninth heaven!

At the moment, the sky was still drizzling, and a layer of mist enveloped the surroundings.

The waterfall floated amidst clouds and fog, like a mortal fairyland.

Arriving at the foot of the waterfall, the voice of the Sovereign Witch resounded: "The cave of my alchemy grandmaster senior is right here."

"He was slain personally by my master, and it was I who sent his skeleton here back then."

"All his lifetime's accumulation of alchemical recipes was placed in this cave. However, back then, I practiced the Martial Way, and those recipes were useless to me. So, at that time, I didn't take them."

"It seems that in the invisible, there is heavenly intent. It was meant for me to lead you here to take those recipes."

Lin Dong raised his eyes to look at the waterfall; the environment here reminded him of the Water Curtain Cave in 'Journey to the West'.

Of course, this place was even more hidden than the Water Curtain Cave.

How could ordinary people imagine that behind that waterfall, a spirit cave was hidden?

Moreover, even if they knew, common people could not enter.

Unless one reached the level of Earth Realm martial artists, able to withstand the counterflow of the waterfall and move upstream—otherwise, entry was impossible.

At this moment, Lin Dong gathered his Inner Qi, forming a pair of wings behind him by utilizing it.

Then, at a speed akin to the speed of sound, he ascended against the current of the waterfall.

After advancing hundreds of meters like this, Lin Dong finally entered the waterfall and arrived inside a cave.

He turned his head and could see that this cave used the waterfall's flow as a door, the surrounding mist as the veil, concealed by lush trees.

Standing inside, one could not see the outside.

And standing outside, one could not see inside.

The environment inside the cave was extremely spacious.

Lin Dong could clearly feel that the spiritual energy inside the cave was very rich. Perfect for martial artists to cultivate!

Besides that, the negative oxygen ions here exceeded those of any therapeutic holy land by dozens of times. For those suffering from respiratory diseases, living here was like undergoing constant oxygen therapy.

Moreover, the temperature in this cave was also extremely suitable. If the outer world was cold, inside would be warm. If the outer world was hot, inside would be cool. Truly an excellent place of warm winters and cool summers.

"You ancient martial artists indeed knew how to choose spirit caves. Whether for martial artists or common people, this is undoubtedly a mortal fairyland." Lin Dong said using mental power to the Sovereign Witch.

The Sovereign Witch laughably said: "Indeed, in our ancient times, there wasn't such overdevelopment as in your modern times."

"Though there are countless more houses in your modern times than in our ancient times, and they are incomparably more beautiful. But when it comes to health preservation, how could your modern high-rise buildings compare to our ancient ones?"

"Any spirit cave from our time is better by countless times than your modern society's therapeutic holy lands."

"Everything in heaven and earth is fair; your modern society, by consuming the heaven and earth's resources, has elevated energy, economy, and technology to the peak in human history… But at the same time, this era of yours is the one with the thinnest spiritual energy."

"Perhaps, the Age of Dharma End, with increasingly thin spiritual energy, wasn't solely due to the slow evolution of heaven and earth, but more so due to humans gradually causing it themselves…"

Hearing the words of the Sovereign Witch, Lin Dong couldn't help but fall into contemplation.

Could it really be as the Sovereign Witch said, that the thinning spiritual energy and the current Age of Dharma End resulted from human overdevelopment?

Could it really be that simple?

Lin Dong didn't dwell excessively on this matter.

He shook his head, not thinking much about this kind of thing anymore.

This is a major issue for humanity; what use would it be no matter how much he thought about it?

At this moment, he walked deeper into the cave.

"Senior Sovereign Witch, is there any danger inside the spirit cave of your alchemy senior?" Lin Dong asked.

The Sovereign Witch shook her head, "Rest assured, for you, there is absolutely no danger."

"Within the spirit cave, there must be some formations guarding it. Otherwise, wouldn't any tomb raider be able to come and disturb the deceased?"

"However, these formations, given your current mastery of formations, can be easily broken."

"Besides, I am here. I came here during my lifetime, naturally knowing the ins and outs of this place."

"That's good, this way, we should be able to return sooner, right?" Lin Dong asked.

The Sovereign Witch did not respond. If it was just about obtaining the recipes, then they could indeed return quickly.

But having come this far, how could they leave so easily?

The Sovereign Witch smiled and asked: "Don't you want to directly refine the Thunder Tribulation Pill here? Don't you want to take the Medicine King and breakthrough your cultivation here?"

"This place is very secluded. Even if you refine the Thunder Tribulation Pill here, take the Medicine King, and cause a breakthrough, drawing heavenly tribulations, it won't cause much trouble."

"If you return to Dan Alliance and go through a breakthrough there, such a commotion will definitely attract huge attention. By then, it's very likely to draw in some Heavenly Realm martial artists. Then, it will bring you endless trouble."

Lin Dong nodded, feeling that the Sovereign Witch made sense.

This place was indeed very secluded.

If he could get ahold of the Thunder Tribulation Pill recipe, he might as well refine it here, then take the Medicine King and seek a breakthrough!

If he could break through to the tenth stage grandmaster here, it would be the best scenario!

However, doing so might take many days.

If Qin Feng of the Dan Alliance returned, it might arouse his suspicion.

But clearly, there was no other choice at the moment.

"Let's go, do you see that tree ahead? A formation is set there, and only by breaking it can the hidden door be opened." The Sovereign Witch's voice echoed again.

Lin Dong shook his head, clearing the concerns from his mind, and proceeded to the tree at the center of the spirit cave as the Sovereign Witch had instructed.

"Circle around this tree three times to the left, three times to the right, then bow to it three times, and you will open the hidden door and see the tomb of my alchemy senior!" The Sovereign Witch said.

This formation belonged to a 'footwork formation'; as long as you followed the required 'footwork,' you could break it.

Many people liked to set such formations within spirit caves.

Because this sort of formation was simple and practical.

Lin Dong then circled around that tree, first turning left three times, then turning right three times.

Next, he stood in front of the big tree and bowed to it three times.

"Boom!"

Sure enough, just as the Sovereign Witch said, a booming sound emitted from the tree root.

Subsequently, a hidden door appeared there, revealing another passage.

It turned out there was more than met the eye inside this spirit cave.

One couldn't help but admire these ancient big shots, designing a spirit cave so intricately.

If anyone recklessly trespassed, they would likely encounter deadly peril.

Lin Dong stepped into that dark passage and soon saw a tombstone.

On the tombstone was inscribed five large characters:

"Tomb of the Pill Emperor Win!"
