At that time, every city would initially receive one, helping them eliminate filth and toxins.

Then Wu Shuangge would collect them regularly.

"Are you planning to build a toilet in every city?" Yang looked shocked, wondering what had rattled Yu Ziqing.

"You know nothing. This is called a sewage treatment plant, a great benefit to the country and its people. Besides, I don't have the time to build so many public toilets," Yu Ziqing sternly corrected Yang.

To be more precise, it was a sewage treatment station.

"The core of this sewage treatment plant is the kind of magical treasure I mentioned that can collect filth and harmful toxins from the sewage.

One per city would suffice.

Do you know how many diseases, even plagues, are caused by poor sanitary conditions?

After wars and epidemics, burning corpses is common knowledge.

I hold a rigorous attitude toward this simulation, and it is absolutely effective.

In the end, it's unknown how many people will benefit, how many will die less, and how many will become less ill.

This is definitely a great thing."

Yang looked at Yu Ziqing's solemn face, with eyes serious and focused, immediately realizing that Yu Ziqing wasn't crazy.

This truly was a great thing for anyone.

Additionally, it allowed Wu Shuangge's magical treasure to quickly advance, a small side benefit.

"If it's just that requirement, not even needing to help with detoxification, it isn't actually difficult."

Yang nodded solemnly and left with Wu Shuangge.

He only needed to let Wu Shuangge understand which runes on the magical treasure are inherently designed to absorb filth and toxins.

Yu Ziqing was not joking at all.

He needed Jinlan Mountain to have its own, sufficiently intimidating Mountain Guardian Treasure.

Every major force had one.

Even though it was just a toilet bucket, once this magical treasure advanced, its deterrent power would be immense.

Ignoring the initial disdain, once they reached the next level, no one would remember what it originally was, only the renowned name it would obtain.

Respectfully, it was called the Mixed Yuan Gold Bowl.

Yes, that was its name, renamed now, and no one should call it a toilet bucket.

Yu Ziqing was brimming with confidence. The almsgiving of hungry ghosts couldn't be spread among ordinary people immediately, and he still needed the sweet rain to assist in expelling devil thoughts through almsgiving hungry ghosts.

He truly couldn't lower the requirements any further, not for lack of trying.

However, now there was another way to infiltrate the lives of ordinary people.

Someday, people like Wu Shuangge and those hungry ghosts could appear openly in the Imperial City of a Divine Dynasty, and Yu Ziqing could openly demonstrate the Hungry Ghost Dao cultivation without any worries.

Yang worked quickly, and with Wu Shuangge's cooperation, even without using the Mixed Yuan Gold Bowl, they were able to separate some runes.

A few days later, the rudimentary version of the sewage treatment core was ready.

Pointing it at the village's composting site for fertilization, with a slight activation, they instantly witnessed the absorption of filth and accumulated toxins by the trial replica.

Unexpectedly for Yu Ziqing, the stench also dissipated.

What remained was completely decomposed fertilizer with no smell, equivalent to a sterilization process.

It appeared as a heap of fluffy, fertile black soil, piled there.

Yu Ziqing approached, observed for a long time, and the more he looked, the more it resembled the organic fertilizer he had spent money buying in his last life, decomposed and sterilized, appearing like fertile black soil without any odor.

Yang walked forward as well, gazing at the organic fertilizer with a hint of astonishment.

Previously a mortal, and even now a Dao cultivator, he was still a mortal, having worked in fields, doing farmwork.

He understood the saying, "fertilizer and water should not be left to outsiders"; decomposed fertilizer was a precious resource for farmers.

The quality of fertilizer directly affected crop yields.

Higher or lower yields, after paying rent or taxes, could sometimes mean the difference between starvation and satiety.

"Ziqing, I think I misunderstood you a few days ago."

Yang was filled with enthusiasm, even pausing the construction of Jinlan Mountain's protective big array to focus on researching the simplest version of the Mixed Yuan Gold Bowl.

Such an item would be irresistible to farmers, city lords, and anyone in power.

Absorbing filth and toxins, reducing disease occurrence, preventing epidemics, and producing the best fertilizer.

These were all positive effects.

These influences were positive representations of Jinlan Mountain and the hungry ghosts to the outside world.

Any farsighted ruler would recognize the benefits.

Once these benefits accumulated and radiated over time, they would enhance the national fortune for those significant Divine Dynasties.

Any of the three Great Divine Dynasties couldn't refuse.

A month later, Yu Ziqing left again, embarking on his Mountain Guardian Treasure cultivation plan.

Of course, the official narrative was about enhancing national fortune.

Uncle Fu in Almsgiving Town received the news again.

He looked at the metal toilet bucket Yu Ziqing placed on the ground, his expression somewhat complex.

"First, take a look at my proposal."

Seeing the bold title, Uncle Fu was at a loss for words.

Blunt and direct: A Way to Enhance the Overall National Fortune.

The title was exceedingly grand.

After reading the contents, Uncle Fu took it more seriously. Though not entirely comprehensible to him, it seemed not to exaggerate or make baseless claims.

In some sections, it explicitly mentioned unknown factors regarding how much special organic fertilizer could increase yields, suggesting comparative experiments.

Uncle Fu was momentarily unsure of how to proceed.

"Uncle Fu, we've been old friends. With this beneficial, state-serving, and people-serving affair, the first person that came to mind was you, of course.

Otherwise, being in Almsgiving Town, I could easily approach Duke Lin."

Upon hearing this, Uncle Fu immediately responded.

"Alright, I'll take this... proposal, and also this sewage treatment magical treasure."

"Don't rush, don't rush."

Yu Ziqing waved his hand, placing nine more on the ground.

"Ten in total, a gift for experimenting freely. Remember to replace them when they're almost full. Otherwise, the filth and toxins accumulated inside can be quite dangerous."

With a cheery send-off, Yu Ziqing promptly said to Cece.

"The first one is sent. Now, deliver a few to Duke Lin Mansion, explaining how to use them and the benefits."

"Now we must cultivate good relationships. In the future, you might have a status akin to the Posthouse Tribe, respected and protected by the Law Code."

Cece covered her mouth, chuckling lightly, unable to comprehend how the young master elevated this matter so high yet made it sensible enough to convince people.

...

Several days later, in Dali Eastern Palace.

The Crown Prince frowned slightly, looking at Yu Ziqing's grandiose proposal, and then at the clean, toilet-shaped magical treasure.

It left him at a loss.

"This..."

"Your Highness, Young Master Qing has always been reliable, and I find his reasoning and evidence plausible, not idle talk. If true, this indeed is a great, state-serving, and people-serving deed."

While Fu didn't disclose his thoughts at Yu Ziqing's end, bringing it here meant only good words.

The Crown Prince naturally didn't understand it, never having tended fields.

"Go, deliver this magical treasure and proposal to Lihuo Institute and have them try it."

She, indeed, didn't grasp these concepts, but knowing who did was enough.

Previously, the addition of sweet rain in almsgiving hungry ghosts proved effective in removing devil thoughts, creating a precedent, and making her confident now.

The magical treasure and proposal were sent to Lihuo Institute.

Arriving from the Crown Prince, it was treated differently than those pleading for funds.

Whether credible or implausible, someone dedicated to implementing it would be found instantly.

Three days later, listening to the explanation from Lihuo Institute, the Crown Prince showed some surprise.

"Do you mean to say, currently, there is no apparent exaggeration?"

"Your Highness, based on the current simulation, indeed so, and even those special fertilizers can be used to cultivate low-level Spirit Plant Jade Rice."
