Smog City is located in a deep pit in Zu'an with a lower terrain, named for being perennially enveloped in smog and toxic miasma.
The lowest class of people live here; dirt, dilapidation, disarray, and decay are its synonyms.
Therefore, this is the favorite place for Wanted Criminals of the Order Heavenly Kingdom.
Xia Port District is the 'rich area' of Smog City, with rows of unique detached villas, each different.
Kong You and Bu Zhihuo Yunsheng, clad in black hooded robes and wearing reusable inner filters over their mouths, walked through the alleys where the air was filled with a faint green smog.
"This broken place doesn't even have villa numbers."
"How long will it take to find it?"
In a nearby corner, a scrawny beggar in rags, with festering sores on his exposed skin, huddled.
Bu Zhihuo Yunsheng approached him and pulled out a fifty-order coins bill from his pocket.
"Do you know where Villa 23 is?"
"I know, I know!"
The beggar's eyes lit up, and he reached out with both hands to grab the money.
Bu Zhihuo Yunsheng raised his hand, holding the bill higher, making him grab at empty air.
"Hey! Lead the way first."
...
In front of a dark green villa, the beggar stopped. He took the bill from Bu Zhihuo Yunsheng's hand, went to the nearest bakery, bought five slices of the cheapest black bread, and began to gnaw on it right there.
"It was quite hard to find."
Bu Zhihuo Yunsheng raised his hand and knocked on the door. A man who looked like a butler opened a small side window and looked at the newcomers.
"You—"
Before he could finish the word, the butler's eyes closed, and he fell straight backward.
Bu Zhihuo Yunsheng appeared behind him just in time and supported him.
After dragging the butler to a corner and hiding him, the two walked through a long corridor lined with purple campanula flowers on both sides and arrived at the main hall.
"Who are you?! How did you get in here?!"
The two guards stationed there saw the intruders. Before they could sound the alarm, Bu Zhihuo Yunsheng knocked them unconscious.
The two took off their inner filters and threw them on the ground.
Because the villa was equipped with air filters and oxygen generators, coupled with an excellent ventilation system, it was possible to breathe normally without wearing reusable inner filters.
"This big villa, this decoration, it's clear they've made a lot of money!"
Bu Zhihuo Yunsheng picked up a croissant from the dining table and praised it while eating.
At this moment, Kong You had already ascended the spiral staircase to the second floor.
They found Jin Xuanya sleeping soundly in the bedroom. Kong You's gun was pressed against her forehead, and she said softly:
"My question is very simple: the method for making the 'key'."
Jin Xuanya's body trembled uncontrollably. Bu Zhihuo Yunsheng took a nightgown and gently draped it over her.
"Don't lie. We were able to find you; you should know what that means."
Bu Zhihuo Yunsheng smiled at Jin Xuanya.
"I don't kill women, but that doesn't mean she won't."
"Oh, by the way, I forgot to introduce her. Her name is Kong You."
Kong You!
Jin Xuanya suddenly looked up, Kong You of the Free Organization!
The main instigator who caused the destruction of the Order Heavenly Kingdom's headquarters, Dream Palace, two days ago, a first-class Wanted Criminal with a bounty of six thousand train coins!
No wonder, no wonder the security downstairs didn't work.
Jin Xuanya recognized the situation before her and took a deep breath.
"One condition: you must release me after you know the manufacturing method."
"Don't worry, beauty, neither of us likes to kill. Everything is negotiable as long as you cooperate."
Jin Xuanya calmed down, put on her nightgown, got up from the waterbed, put on her slippers, and pulled open the gauze curtain behind the bed.
Behind the red gauze curtain, accompanied by the clacking sound of gears, a secret door slowly opened.
"Goodness, there's even a secret room."
Kong You conjured a silver chain out of thin air and locked a collar around Jin Xuanya's neck.
"Behave yourself. This is an extraordinary item. As soon as I have a thought, your head will appear somewhere else."
Jin Xuanya felt the coldness on her neck, daring not to be angry but unable to speak.
And so, the three of them walked in together, and the door closed again.
Behind the door was a pool, and in the center of the pool was a grand altar.
On the altar was a silver greed holy grail, inlaid with various exquisite gems.
"This is the greed holy grail."
"By offering four different hearts, you can obtain the 'key' to open the treasure chest."
"That simple?"
Bu Zhihuo Yunsheng leaned forward and looked at the greed holy grail.
The greed holy grail contained more than half a cup of blood, and Bu Zhihuo Yunsheng's face was reflected in the blood's surface.
Jin Xuanya showed a look of disdain and continued:
"These four hearts are the Heart of Love, the Heart of Hate, the Heart of Love-Hate, and the most difficult one, the Heart of Love-Hate-Love."
Bu Zhihuo Yunsheng turned around and looked at Jin Xuanya.
"What does that mean? It sounds so abstract."
"Feeding blood to the holy grail will bind you to it, forming a contract."
"The Heart of Love is the heart of someone who truly loves me, and the others are similar."
"So the Heart of Love-Hate is someone who both loves and hates you?"
"It's first love, then hate," Jin Xuanya corrected.
"Oh ~ So Love-Hate-Love is, first they love you, then they hate you, and then they still love you? This is too complicated."
"As expected of a key that can open an eighth-level treasure chest, it is indeed very difficult to make."
Listening to Jin Xuanya explain the method for making the 'key', Kong You couldn't help but frown.
She tightened the chain in her hand, dragging Jin Xuanya closer, her beautiful eyes fixed on her.
"How do you prove what you're saying?"
Jin Xuanya's face turned red from being choked.
"Cough! Cough cough! How do you want me to prove it? I've already said everything I can!"
"Make a 'key' now."
