Chapter 645: Chapter 284: Golden Core Stage Core Structure—[Grotto Heaven] (3)

Compared to using other magical treasures, using this Lifebound Magical Treasure consumes less.

Since that’s the case, what are we waiting for?

Sell everything off for scrap and upgrade this Grotto Heaven Magical Treasure first.

When it comes to housing buildings, special attention is required because even its Spirit Effect has a dedicated ”annotation.”

The more buildings it houses, the greater the power.

Not to mention building new constructions, just accommodating all existing buildings into the Grotto Heaven requires an unknown amount of Void Nether Stone.

Is one mine enough?

Hard to say.

Then Ji Yuan started pondering how to sell everything for scrap to first upgrade this level 1 Grotto Heaven.

30,000 Mid-grade Spirit Stones... if it wasn’t for that one time of scraping by without the panel.

Ji Yuan would now upgrade with ease.

But after scraping, Ji Yuan looked back at the empty Spirit Vein and couldn’t even consider it a Spirit Vein anymore.

Because there wasn’t a single Spirit Stone inside.

Without enough Spirit Stones as support, the building effects of Spirit Stones can’t even be initiated.

’Damn it, this Lifebound Magical Treasure has really taken me back to the starting line.’

Ji Yuan thought as he took a few steps out of the underground cave.

Returning to the surface Cave Mansion, he called for Tu Yue.

What do you do when the master runs out of money?

Naturally, you go find the little maid.

”What’s the production like these months... well, these past few days?”

Ji Yuan originally intended to say months, but then remembered he had already collected from Tu Yue once a few days ago when he came back from outside.

Tu Yue said nothing, only obediently handed over her Storage Bag with both hands.

Ji Yuan took a look.

There wasn’t a single Spirit Stone, just a bit of Blood Essence and Spiritual Soil, the low-grade backup.

Ji Yuan hadn’t thought much of those things for countless years.

But now... he relished them.

He picked them up one by one, placing them into his own Storage Bag, then returned the now-empty Storage Bag to Tu Yue.

After collecting from the little maid, Ji Yuan pondered how much he had that could be sold.

First, some inconsequential Immortal Material, and Elixirs and Spiritual Artifacts he created while guarding the Alchemy Square.

If all of these were sold... it could be about 3,000 Mid-grade Spirit Stones.

And this is already Ji Yuan being extremely diligent, and with some help from Celestial Craft Square.

If it was a common cultivator, it would be less.

Other items, frequently used Spiritual Artifacts definitely couldn’t be sold; can’t overlook one’s fundamentals, affecting one’s combat power.

Thousand-year-old Spirit Milk couldn’t be sold, and Talisman Treasures certainly couldn’t be sold.

Thinking over this, there weren’t many things that could be sold... mostly because what could be sold had already been sold before.

”Damn!”

Unable to hold back, Ji Yuan cursed in his heart again.

As for other things, those cultivation techniques could actually be copied and sold, but that would have to be far away, not in the Water Dragon Sect.

Firstly, most of Ji Yuan’s cultivation techniques actually came from the Water Dragon Sect.

Secondly, selling cultivation techniques is something that’s frowned upon by the Immortal Sect, and Ji Yuan is worried about unnecessary trouble.

Later, he could go to Medicine King Valley, find a place and see if he could sell some.

Right!

Dong Qian has left, but the shop she left is still there, and I had previously consigned quite a bit there, there should be some income there.

Can take a look soon.

If that’s still not enough, Ji Yuan can only wait to head to the Alchemy Square later to borrow a bit from Li Changhe.

Going to Hua Yaoyue for a favor certainly would work.

But Ji Yuan couldn’t bring himself to ask.

Actually, the best method is to sell the Fountain of Eternal Youth, but right now, it’s indeed not a good time to sell.

He’s worried that selling this will prompt the Six Immortal Sects to act; if they mobilize connections directly and come for him, that would be hard to explain.

After finishing his contemplation, Ji Yuan gathered his belongings and headed straight for All Things Island.

There were fewer sect disciples; naturally, the originally bustling All Things Island was now much quieter.

Upon landing, Ji Yuan released his Divine Sense, sweeping over most of the island, only to find many shops already closed.

It truly was desolate now.

But fortunately, Dong Qian’s shop was still there, and it seemed business was decent; even now, there were still four or five customers inside the shop.

Ji Yuan quietly arrived at the door of ”Miraculous Medicine Shop,” where the sharp-eyed Shi Xiuer immediately spotted him.

”Senior Brother Ji!”

Shi Xiuer greeted him with a trace of excitement, causing the other disciples to also pay their respects to Ji Yuan.

Before long, those Qi Cultivation cultivators completed their purchases, and unlike usual, they didn’t even bargain this time, paid spirit stones, and hurriedly left.

”Senior Brother Ji, you’re finally back!”

Seeing there were no outsiders, Shi Xiuer spoke somewhat emotionally.

”What’s up? Is there a problem with the shop?”

”No... it’s just that Senior Sister Dong came back once not long ago. She said... she said...”

”What did she say?”

Ji Yuan’s tone became heavier.

”She said that after this, the shop is yours, and she also left a Storage Bag with me saying it’s for you.”

As Shi Xiuer spoke, her voice became smaller, finally obediently handing over a Storage Bag.

Ji Yuan didn’t question it. Upon receiving it, he swept it with his Divine Sense and was immediately stunned.

His expression became vacant and bewildered, even feeling somewhat disoriented.

Indeed, his feelings for Dong Qian were not very deep, so when he saw her farewell letter recently, he did not feel too sad.

He merely thought Dong Qian had gone to a land abundant with Demon Pills.

But now, upon seeing the contents of this Storage Bag.

He realized that Dong Qian’s feelings for him... were indeed deep.

For a moment, Ji Yuan felt a sourness in his chest.

He clutched his chest and sat down on the ground.

”Senior Brother Ji... Brother Ji?” Shi Xiuer became somewhat panicked and quickly called out.

”I’m fine, you go out first. I just need a moment alone.”

Ji Yuan waved his hand, speaking without lifting his head.

”Alright.”

Shi Xiuer quickly responded, then tip-toed out of the shop, thoughtfully closing the door.

With no outsiders left, Ji Yuan let out a long sigh, and his whole being seemed lost.

He lowered his head, staring blankly at the ground.

The Storage Bag contained not letters, nor Jade Scrolls, and certainly no Treasures of Heaven and Earth or Spirit Pills.

Just simple Spirit Stones.

Spirit Stones were what Ji Yuan most needed at present.

All spread out on the ground, so Ji Yuan knew the exact count with a sweep of his Divine Sense.

8,232 Mid-grade Spirit Stones, 234 Low-grade Spirit Stones, plus 9 Broken Spirits left.

She could’ve given 9,000 Mid-grade Spirit Stones or 8,000 Mid-grade Spirit Stones.

But she just had to give exactly 8,232 Mid-grade Spirit Stones!

Even took out the last 9 Broken Spirits.

Ji Yuan leaned back, lying on the ground, his mind filled with scenes from his time with Dong Qian...

”Senior Sister Dong...”

Ji Yuan murmured softly.

The only response was the lamenting evening wind outside the door and the yellowing autumn leaves outside the window.
