Genshin Impact's Incense Burner Of Liyue.

After leaving Wangsheng Funeral Parlor, Gu Sanqiu bought a large assortment of street snacks. Then, ensuring no one was paying attention, he leaped onto a rooftop, spreading his mental energy in all directions.

"Medicine Furnace Adeptus… Medicine Furnace Adeptus…"

The telepathic call was quickly interrupted by the sharp meow of a cat.

"Come meet me here."

"Guess that worked," Gu Sanqiu muttered with a smirk as he made his way toward the source of the mental signal.

"I have to say, kid, pulling stunts like this in Liyue Harbor is a good way to land yourself in trouble," the Medicine Furnace Adeptus grumbled, hands clasped behind his back, as he eyed the bags of food Gu Sanqiu carried.

"If this were the old days, you'd already be locked up and thoroughly interrogated."

"Times have changed, Senior Medicine Furnace," Gu Sanqiu replied with a smile. "These days, very few people in Liyue Harbor have the capacity to do something like this. And I know all of them—they know me too. No one's going to make a fuss."

"Do you even understand the weight of being Liyue Harbor's 'Crown Prince'?"

The Adeptus let out a sigh. "Crown Prince? Since when did the Crown Prince have to handle so much? Why not let the Qixing take care of it?"

"As if they'd know what to do," Gu Sanqiu scoffed. "Besides, I'm doing all of this for Xiao."

"You're no Crown Prince—you're a Liyue Warlord. The other day you practically led a royal campaign," the Adeptus remarked as he sat down on the ground. "So, what do you want from this old man?"

"I came to ask about the Battle Soul of Killing Intent."

Gu Sanqiu hesitated before continuing, "I looked through my family's records, but it seems anything about that technique was removed. The text suggested that if the Gu family mastered it, we might… misuse it."

"Today, I wanted to ask about the details—like how to enhance it after forming a Battle Soul, or whether it's possible to fuse multiple Battle Souls together."

"Erased from the records, huh?"

The Adeptus frowned slightly, then shot Gu Sanqiu an odd look.

"I see now. Your ancestors were quite wise."

Thanks, I'll take that as a backhanded compliment.

"Still, since the Battle Soul has already resurfaced in this era, I suppose it wouldn't hurt to tell you a few things."

The Adeptus continued, "Forming it requires complete unity of mind and spirit, as well as robust qi and blood. Otherwise, success is unlikely."

"Even in those days, only a select few in the Millelith could use the Battle Soul—and that was after consuming high-grade spiritual materials."

"Some could even amplify their Battle Souls by absorbing elemental crystals or relics like Eternal Embers, which contain pure elemental energy."

He paused before adding, "I'll tell you this: the Battle Soul is versatile. It can even be fused with others. Most of those wild ideas in your head? Entirely possible."

"It's a power built on the concept of an External Domain, allowing each user to retain their unique attributes while acting as one. That's its defining feature."

So, it really can produce humanoid constructs akin to Gundams.

Gu Sanqiu latched onto the key point. "But from what you're saying, it sounds like the energy cost is enormous."

"Did you bring any pills with you?"

"I did."

Gu Sanqiu handed over a pill.

"Hmm, the quality's even better than the last batch I saw. Your talent is frightening," the Adeptus said, genuinely impressed.

"But let's stay on topic. Even with this type of pill dissolved in water, it could only sustain a small squad of Millelith for a single battle back in the day."

"A single battle?!"

Gu Sanqiu's eyes widened. "I understand how intense those fights must have been, but these pills have gone through generations of improvement. That seems… excessive."

Take Xingqiu, for instance—this guy could spam his ultimate like it was a normal attack after taking one of these pills. The enhanced energy and strengthened meridians made it so there was no risk of overloading his body.

And it's still not enough?

"That's just how much energy it consumes," the Adeptus said, tossing the pill back to him. "If not for the blessings of Liyue Harbor and Qingce Village compensating for the energy costs last time, none of those kids would have been able to stand after the fight."

"The sudden surge of power can turn the tide of battle, but the aftermath is brutal."

"Back then, the only way to replenish that kind of energy was with shards of gods or special derivatives imbued with 'authority.'"

The Adeptus sighed. "In an era without gods or wars, the fact that your pills can achieve this much is something to be proud of."

"So, should I be smiling right now?"

Gu Sanqiu's mouth twitched. "It doesn't matter how impressive you guys were back then. People today still need to rely on modern recovery items to fuel this power. Got any solutions, Senior?"

"That's why my advice is simple: don't reveal it."

The Adeptus calmly snacked on the offerings Gu Sanqiu had brought.

"The Battle Soul's power is too overwhelming. Who do you plan to use it against if you awaken it now?"

"Who else? The Fatui running around Liyue, of course. They're perfect punching bags."

The Adeptus gave him a long look. "You don't sound serious."

"Oh, as long as my friends don't get hurt, I couldn't care less."

"This is power from the Archon War—every nation likely has some record of it. If you make this a military standard, you'll scare your neighbors to death."

"Really?" Gu Sanqiu scoffed. "Aside from Mondstadt, why should I care what my neighbors think? If they've got a problem, let them come at me. I'll just head back to Minlin and call reinforcements to teach them some manners."

"That's not the point," the Adeptus muttered, wiping his hands. Finding them unsatisfactory, he licked them clean.

"You're not stupid. Liyue isn't what it used to be."

"Back then, the Battle Soul was under the Geo Archon's direct command. Your family led the charge, acting as his personal guards."

"But now? Frankly, neither the Geo Archon nor your family holds that level of power anymore. Ever heard of 'a treasure invites trouble'?"

Gu Sanqiu scratched his head. "I thought Adepti weren't supposed to understand these kinds of things. You're surprisingly sharp, Senior."

"Dealing with your family long enough would teach even a pig a few lessons."

"Comparing yourself to a pig doesn't seem flattering."

"I said even a pig. Listen carefully."
