"High-class!"

The Crocodile stopped in the passage, no longer moving forward; they had reached the deepest part of the passage.

In Weiwei's lair, deep within the Cave lies a massive Cave, filled with Weiwei 'Weiwei toys and bed.

It remains the same here.

The overall structure looks almost identical to Weiwei's lair.

The only truly astonishing thing was how enormous the Cave was, and how there was this damn Cave inside.

"Fall?"

A look of disbelief flashed in Chen Fan's eyes. He stood there, stunned, staring blankly at the scene before him.

He never imagined that one day he would find a waterfall deep underground.

He didn't know how many meters underground they were, but he was certain of one thing: they were definitely deep underground.

He frowned, carefully observing the scene before him. A large amount of groundwater was seeping from the wall, forming a waterfall at a protrusion in the rock face.

The waterfall is narrow, not particularly wide. Below it is a pool of water, on which grows a Blood Lotus. The scene inside the Cave is rather simple, with nothing else besides the waterfall and the lotus below it.

There was also a simple bed, not like a human bed, but more like a Weiwei bed, made of Withered Grass and fur, but it had obviously been abandoned for a long time.

Just then...

Weiwei let out a whimpering sound, climbed onto the bed next to it, and sniffed it gently.

"Could the lotus flowers beneath that waterfall be some Heavenly Materials and Earthly Treasures?"

Following behind Chen Fan, Zhou Mo asked tentatively, his eyes scanning the entire Cave interior.

Chen Fan remained silent, but strode to the waterfall and looked at the lotus flower below it. A panel slowly appeared in front of him.

Name of the Exotic Treasure: Snow Lotus (mature).

"Exotic Treasure Grade": Green Grade.

"Exotic Treasure Effect": A special kind of Heavenly Materials and Earthly Treasures that requires a hundred years of nurturing in a special environment to mature. It is a product of Heaven and Earth and can be used for Alchemy, Artifact Refining, and array formation.

P. S.: If picked before it is fully ripe, it will release an extremely strong poison that will affect an area within a mile.

After ripening and harvesting, the fruit should be placed in a low-temperature environment for proper storage within one hour, otherwise its medicinal properties will be lost.

The information on the panel is extremely simple, with no other information.

This is indeed a rare and Heavenly Materials and Earthly Treasures, but unlike the Mountain-Skeleton Embryo, it can be used for Alchemy, Artifact Refining, and more.

Aside from its use in formations, it serves no other purpose. Unlike the Mountain-Skeleton Embryo, which can be used to maintain the stability of underground cavity structures.

Chen Fan stood in front of the waterfall, quietly observing the scene, without immediately going forward to pick any fruit.

A continuous roar echoed from the depths of the Cave, as a massive waterfall cascaded down like a silver river into a deep pool, creating a mist that filled the air.

This Snow Lotus grows in the pond, floating on the surface of the water.

Completely white, without a speck of dust, its nine petals unfolded, their tips gleaming with a cool, serene light.

It looks exceptionally appealing, giving the impression that it would taste great when used to stew chicken.

"Station Master."

Zhou Mo held the Great Knife in his hand, carefully surveying the Cave, and hesitantly asked, "Wasn't it said that a great person once lived here? Why haven't I seen any signs of habitation? There should at least be a bed or a meditation cushion or something like that, right?"

Chen Fan shook his head. "What I know is only the message conveyed by the Wraith King. Since even the Wraith King doesn't dare to address him by name, he must be a very important person. Such an important person might usually cultivate in the air, sitting cross-legged and detached from worldly affairs."

Actually, it might not be a person, for example... it could be someone Weiwei parents.

But he felt that this was unlikely.

After all, it's unlikely that a Crocodile could carry such a large Hammer and smash a crater into the mountain.

The That One the Wraith King mentioned is very likely a powerful Cultivator, while Weiwei's parents are their pets.

Although he didn't know what use this Snow Lotus could have for the time being, it was still a Heavenly Materials and Earthly Treasures and precious herb, and having it was better than not having it. Moreover, his Warehouse was just big enough to store the Snow Lotus, so he didn't have to worry about losing its medicinal properties.

But his biggest goal on this trip wasn't the Snow Lotus, but the Mountain-Skeleton Embryo. So far, he hadn't seen a trace of Mountain-Skeleton Embryo. And the Cave was completely empty, almost entirely exposed. If there was any possibility of finding Snow Lotus, it would only be in this pool of water.

"Weiwei."

Chen Fan turned his head to look at Weiwei, who was lying to the side, and called out softly. Since entering this Cave, Weiwei had been feeling a little down, which he could understand.

After Weiwei out another whimper, it plunged into the pool and disappeared, splashing water everywhere. It emerged again after a while, this time with a Mountain-Skeleton Embryo in its mouth.

"Weiwei, did you grab the wrong one?"

Chen Fan frowned and looked at the thing Weiwei was holding in her mouth.

He had seen the Mountain-Skeleton Embryo, which was placed in the Eerie Fire. The Mountain-Skeleton Embryo was a slowly pulsating, Dark Red tumor, about the size of a human brain, and looked like a tumor that had been peeled off.

The Mountain-Skeleton Embryo in Weiwei's mouth was not Dark Red, but a Brown color, like mountain soil.

It wasn't a ball of flesh at all; instead, it was a bamboo shoot.

Weiwei released its mouth, placed the bamboo shoot in its mouth on the ground beside the pond, and let out a whimper, as if to say, "This is the same taste as the others; I don't know why the shape is different."

Chen Fan stepped forward and looked at the panel that had emerged from the bamboo shoot.

One "Exotic Treasure name": Mountain Embryo.

"Exotic Treasure Grade": Yellow Grade.

"Exotic Treasure Effect": A special kind of Heavenly Materials and Earthly Treasures of Heaven and Earth absorbed by the sun and moon in the mountains. It can be used for Alchemy, Artifact Refining, and array formation.

It is extremely fragile during its growth period. If it suffers from violent earthquakes, major wars, or other upheavals, it will perish prematurely and turn into Mountain-Skeleton Embryo.

Chen Fan's expression was complicated as he silently stared at the panel in front of him.

Weiwei, you're right, this thing really is the same as the Mountain-Skeleton Embryo.

However, this grade is higher, a full Yellow Grade, the same grade as his Vehicle Workshop. A mature one is Mountain Embryo, and one that dies prematurely is Mountain-Skeleton Embryo.

But...

He was on the verge of tears. He admitted it was a good product and that he could definitely sell it for a good price after the Rainy Season, if he found someone who needed it.

The problem is, this isn't what he needs right now.

All he needs now is a dead Mountain-Skeleton Embryo, one dead one is enough, to use the dead Mountain-Skeleton Embryo to obtain the direction for Qualitative Transformation upgrade of the Training Room.

He ended up finding a better Mountain Embryo, which was more valuable, but it was no longer useful.

This is like someone exploring in the wild, starving for three or four days, finally finding an abandoned human settlement, only to find no food or water, but instead a bunch of Eerie Stone —what good are they?

But...

Chen Fan hesitated. Perhaps this thing could be used. He would try it when he got home. If it didn't work, he would see if he could smash it to death with a stick and then turn it back into Mountain-Skeleton Embryo.

If something dies halfway through its growth stage, it will become Mountain-Skeleton Embryo. I wonder what it will become if it is killed after it has matured.

He then glanced around and prepared to return.

In this Cave, which was also the old lair of Weiwei's parents, he obtained two Heavenly Materials and Earthly Treasures.

Both of these Heavenly Materials and Earthly Treasures are quite Rare, but they don't have any practical use, unlike the Mountain-Skeleton Embryo, which has the function of stabilizing Cave.

Before leaving, he squinted slightly, gazing at the waterfall above the pool.

This waterfall isn't very wide, but it has a considerable volume of water.

If nothing unexpected happens, this water is likely rainwater absorbed by the mountain, filtered underground, and then seeping here.

This further proves his guess that the rainwater during the Rainy Season is not just water, but more like a tonic, which greatly helps the growth of Heavenly Materials and Earthly Treasures and the cultivation of Strange Entities.

But it doesn't seem to offer any benefit to humans.

The Snow Lotus growing on the pond continuously absorb rainwater until they mature.

Is there anything else at the bottom of the pool?

Chen Fan looked at the Crocodile, only to see Crocodile shake its head, as if to say there was nothing underwater.

They didn't linger and headed home.

The way back was a little faster than the way we came.

In less than half an hour, they crawled out of the Cave deep underground.

Chen Fan climbed off the Crocodile's back, looked around, and saw that the rainwater was still being absorbed by the mountainside, which made him breathe a slight sigh of relief.

All the rainwater that falls on this mountain collects in a pool to cultivate Snow Lotus.

He was actually a little worried that if the Snow Lotus was removed, the mountain would no longer absorb rainwater, and his Rear Base in the Sinkhole might face the risk of flooding.

Now there's no need to worry, but he's more curious: since this rainwater can nurture Snow Lotus, then in a way, this pool is also a treasure.

However, since there was no display panel showing the specific composition of the rainwater, he didn't know how much Weiwei liked the pool of water. Perhaps he would be able to find out the specific purpose of the pool later when he had more information.

So what's next...?

He glanced around, then climbed back onto the Crocodile's back, ready to go home.

The Snow Lotus has been picked and must be placed in a suitable storage environment within an hour, otherwise its medicinal properties will be lost. After settling the Snow Lotus, he plans to come back again.

He admitted that these two Heavenly Materials and Earthly Treasures were indeed a very good harvest.

However, at this time his foundation was too weak and his base too poor.

These two Heavenly Materials and Earthly Treasures didn't have a particularly good effect on him. He actually wanted some more mundane gains, like Eerie Stone or 50,000 Eerie Stone.

With these Eerie Stones, he could push his Meat Grinder plan even further.

Weiwei, you've been here all these years and you've created two latrines. Weiwei parents must have created countless latrines. If we could find all of them, wouldn't we be rich?

After settling the Snow Lotus, he would come over to find the latrine.

Soon.

Chen Fan rushed back to the Camp without stopping, flipped off the Crocodile's back, handed the Snow Lotus in his hand directly to Wang Kui, and quickly gave him instructions.

Store in a cool environment and keep it in Warehouse.

Then he strode into the depths of the Cave.

After consuming 32 Eerie Stone, a phantom image of a building composed of white lines slowly appeared before me and quickly solidified.

A three-story Stone House rose out of thin air.

Now comes the moment to witness a miracle.

Chen Fan took a deep breath, and somewhat nervously took out the brownish -Yellow Grade clay from his pocket, carefully placing it in the corner of the room before preparing to continue upgrading.

Even Mountain Embryo is still an embryo.

Hopefully, this will be helpful. His main concern is that he's genuinely unsure whether killing the Mountain Embryo will turn it into Mountain-Skeleton Embryo.

It might even end up stillborn.

After consuming another 50 Eerie Stone, the level 3 Wooden Hut in front of me was upgraded to level 4, and a panel appeared.

The Wooden Hut has been upgraded to Level 4, becoming Stone House and much more sturdy.

Please select an upgrade direction.

"1: The Artifact Workshop allows you to forge magical Spirit Treasure using Forging Ghost Material. Artifact Refiner is required to oversee the workshop."

"2: The Alchemy Workshop allows you to refine Pills using Ghost Material. Alchemist must be present to oversee it."

"3: Qualitative Transformation (Spirit-Nurturing Pavilion): Allows Cultivator to quickly cultivate and learn Martial Technique here. (Rare)"

Without the slightest hesitation, Chen Fan instantly chose the third upgrade option. He could take his time looking at the panel; he'd choose first.

"Call..."

Chen Fan took a deep breath, looked at the upgraded "Spirit-Nurturing Pavilion" in front of him, and couldn't help but grin. If he weren't a little concerned about his image, he would have wanted to burst into laughter right now!

Without the Mountain-Skeleton Embryo, it is indeed impossible to obtain the upgrade path for the "Training Room".

However, it can provide upgrade options for the "Spirit-Nurturing Pavilion"!

Although both are "Rare" qualitative Qualitative Transformation.

However, there are differences between Rare. Putting everything else aside, just looking at the names tells you that these two are not in the same league. The Spirit-Nurturing Pavilion sounds much better than that Training Room.

And...

It is worth mentioning.

This Stone House was built deep inside the Cave. After it was upgraded to the "Spirit-Nurturing Pavilion", it was obviously too small to fit inside. The white lines carved a hole in the Cave wall on their own and squeezed the enlarged Spirit-Nurturing Pavilion inside. This is different from other buildings. Other buildings simply cannot fit the space if they are not large enough, and they will not dig a hole on their own.

The upgraded Spirit-Nurturing Pavilion occupies a much larger area than the old Wooden Hut.

The entire structure is almost perfectly embedded in the mountain, with only one door visible on the inner wall of the Cave.

Push the door open and enter.

What comes into view is an extremely smooth, continuous Black Jade Stone Communal Sleeping Platform.

"Advanced!"

Chen Fan gave his assessment with a sigh, "Floor... what a strange word! His Headquarters is still just clods of earth, only compacted by the Crocodile running around. His Headquarters doesn't even have a floor. The Spirit-Nurturing Pavilion has a floor."

I reached out and touched the floor; it was quite cold. It must be some kind of jade. If I dug it up and sold it, I should be able to make some money.

There were no rooms inside.

It was a vast, empty space.

It is tens of meters high and covers an area of several thousand square meters.

It's obvious that there's more to it than meets the Heaven and Earth. The building's silhouette isn't nearly as big as it appears from the outside. It's Heaven and Earth like a "Mustard-Seed Room"—the interior is much larger than it looks from the outside.

It's a bit foggy; it hasn't started yet.

He connected the Spirit-Nurturing Pavilion and the Eerie Fire with Copper Pipe and activated them.

The next moment -

The entire Spirit-Nurturing Pavilion suddenly lit up!
