"The normal Spiritual Energy Cannon operates like this."

"I see, Uncle, how many Spirit Stones does it take to activate this Spiritual Energy Cannon once?" Ji Yuan asked curiously.

Yun Wannian stroked his beard and laughed, "The Spiritual Energy Cannon has three levels of attack: the first level has the lowest attack, similar to a late-stage Foundation Establishment cultivator's full force strike. It estimates that one activation needs 80 Mid-grade Spirit Stones."

"The second level is equivalent to the peak of Foundation Establishment cultivator's full strike, and one activation requires 300 Spirit Stones."

"The third level is comparable to a full force strike from an early-stage Golden Core cultivator. Activating the third level... requires at least 900 Mid-grade Spirit Stones."

"Furthermore, this third level causes significant damage to the Spiritual Energy Cannon, like the one in front of us, if used at the third level, could at most be activated two more times before it ends up completely destroyed."

Yun Wannian provided detailed explanations, which matched Ji Yuan's internal speculation.

Take the second level for example, a peak Foundation Establishment full force strike is actually similar to the effect of a Celestial Thunder Seed.

But a single Celestial Thunder Seed's price is about 500 Mid-grade Spirit Stones, while the Spiritual Energy Cannon here requires 300 Mid-grade Spirit Stones for a single activation... cheaper, but it's immobile and less convenient to use.

Therefore, the price for a single activation being cheaper seems fair.

"In short, when you see the Array Pattern on the Spiritual Energy Cannon starting to blur, don't use it anymore," Yun Wannian advised.

"Alright, thank you..."

Before Ji Yuan could speak, a white shadow flashed before him, followed by a person appearing, with his back to Ji Yuan, slowly saying:

"What is difficult about this? I can fix it."

Yun Wannian listened with his eyes wide open, looking at his son, "You can repair the Spiritual Energy Cannon??"

"Heh."

Yun Qianzai waved his sleeve with a sneer, "What is difficult about this!"

Uncle Yun stood up as well, glaring, "Last time I sent you a message, you said you still couldn't do it. Now, you're not even helping with the family's affairs."

Yun Qianzai glanced at him with a slightly raised head and said flatly, "Please address me as Ancestor."

Ji Yuan listened to their family conversation, unable to stop himself from twitching his mouth... having Yun Qianzai in the family is truly a love-hate situation, talented yet temperamentally peculiar.

"Uncle Yun, how many Spirit Stones for this Spiritual Energy Cannon, I'll buy it."

Ji Yuan, fearing the argument between Uncle Yun and Yun Qianzai might escalate, quickly stood up to mediate.

"No need for Spirit Stones, since you need it, I will gift it to you," Yun Wannian replied with a chuckle.

"Indeed, it's just gathering dust in the treasury, take it with you," added Uncle Yun.

"That won't do, for something so valuable, let's do this, accept these goods... don't mind the quantity being small."

Ji Yuan took out a Storage Bag and handed it to Yun Wannian.

Inside were some Spirit Stones, a Mid-grade Spiritual Artifact, plus some Tier Two Elixirs and Talismans, and even one Tier One Foundation Establishment Pill, all totaling roughly 1500 Mid-grade Spirit Stones if converted.

A brand new Spiritual Energy Cannon is priced around 3000 Mid-grade Spirit Stones.

Now for this second-hand item, selling it for 1500 is actually on the higher side; the reason Ji Yuan offered this price was to avoid owing too many favors.

Owing too many favors is detrimental to Cultivation.

The reason for this price was fully concealed.

It showed that he had exhausted his assets to buy this Spiritual Energy Cannon; otherwise, casually taking out 1500 Mid-grade Spirit Stones... would be quite terrifying as well.

"No need for Spirit Stones, Junior Brother just take it back."

Yun Qianzai took back the Storage Bag from Yun Wannian and tossed it to Ji Yuan.

"Yes, exactly, Junior Brother just keep it," Yun Wannian hurriedly said.

Yet Ji Yuan still handed over the Storage Bag, then turned and stored away the Spiritual Energy Cannon, "Senior Brother need not persuade, without you accepting these Spirit Stones, I will not take the Spiritual Energy Cannon."

"You..."

Yun Qianzai frowned slightly, but he knew Ji Yuan's personality; ultimately, he did not insist.

The Yun Family gave freely, and Ji Yuan got what he needed; this meeting was somewhat satisfactory for everyone.

Just as Ji Yuan returned to his seat, he invaded the Storage Bag with his Divine Sense.

The Spiritual Energy Cannon... did not display the familiar text characters to him.

There was no line of white text.

Could it be that the Spiritual Energy Cannon does not count as a building?

Cannot be upgraded?

That shouldn't be; placing this here, why would it not count as a building; defensive buildings count as buildings too.

Before it wasn't mine, not being able to upgrade was normal, but now that I've taken possession of it... Ji Yuan thought, a flash of insight illuminated his mind, and suddenly he understood.

As he saw everyone had returned to their seats, he moved his Heart Thought and retrieved the Spiritual Energy Cannon he had just stored away and placed it in the middle of the venue.

"Hmm?"

Yun Wannian quickly looked over, slightly frowning, appearing puzzled.

The others had similar expressions.

Ji Yuan chuckled, "Just thrilled, couldn't resist taking another look."

"Haha, good, Junior Brother, look as much as you like." Yun Wannian chuckled while stroking his beard.

"No more looking, no more looking."

Ji Yuan made a gesture and stored the **Spiritual Energy Cannon** back into the Storage Bag.

Objective accomplished.

Because just moments ago, he had confirmed his guess and received the answer he wanted.

The Spiritual Energy Cannon became **Spiritual Energy Cannon**.

'It seems that this building inside the Storage Bag cannot exert effects nor be upgraded, similar to my portable **Cave Mansion**, all needing to be displayed to be useable.'
