So what if I have a few billion concubines while I'm cultivating immortality?

Yu Fengling quickly followed, and the Three Talents Bracelet on her wrist lit up faintly, illuminating the way ahead.

The stone steps descend for about ten feet, ending at a heavy bronze door.

The door is engraved with ancient cloud patterns, and there is a groove in the center, resembling some kind of token.

Qin Xiao glanced at it, then reached out and pressed his hand against the door, his nascent soul spiritual power flowing in and out.

"Buzz..."

The cloud patterns on the bronze door lit up one by one, and then opened inward.

Behind the door was a small stone chamber, about three zhang square.

The room was empty except for a stone platform in the center, on which sat a jade box covered in dust.

Qin Xiao walked to the stone platform and brushed the dust off the jade box. The box had no restrictions and opened easily with a gentle lift.

There were only two items inside the box.

A dull blue jade slip and a palm-sized black token.

Qin Xiao first picked up the jade slip and probed it with his divine sense.

The jade slip contained very little information, only a few words:

"I, Yu Canghai, the third-generation ancestor of the Yu clan, by chance inherited the legacy of my predecessors and glimpsed the basics of immortality. However, due to my limited aptitude, I only reached the third level of Qi Refining before my lifespan ended there. I leave behind this 'Miscellaneous Records of Qi Induction' and the 'Heavenly Craft Token' for future generations. If any of my descendants have the affinity for immortality, they may use this token to go to the 'Valley of Heavenly Craft' to give it a try. However, the spiritual energy of this world is declining day by day, and the path to immortality has been cut off. Be careful, be careful..."

Attached to the end is a rudimentary "Miscellaneous Records on Qi Induction," which is even more rudimentary than the "Qi Induction Techniques" obtained by Qingyang Daoist. It contains only the most basic methods of qi induction and contains many errors.

"Tiangong Valley?"

Qin Xiao muttered to himself as he picked up the black token.

The token felt cold to the touch, with the two ancient seal characters "Tiangong" engraved on the front.

"Husband, what is this?"

Yu Fengling curiously leaned over to take a look.

"Things left behind by your Yu family's third-generation ancestor."

Qin Xiao briefly explained the contents of the jade slip, saying, "This Heavenly Crafting Token might be a clue."

"Heavenly Craft Valley... I've never heard of this place."

Yu Fengling frowned in thought, "However, there might be records in the royal library. Many ancient books from before the founding of the Yu Kingdom are stored there."

Qin Xiao put away the jade slip and token: "Go take a look."

The two left the underground stone chamber, restored the entrance to its original state, and headed to the palace library.

At that moment, guards were stationed outside the building. Upon seeing Yu Fengling arrive, they quickly bowed.

"I need to consult ancient books and maps from before the founding of the People's Republic of China, especially records related to 'Tiangong Valley'."

Yu Fengling gave the instructions.

"Yes, Your Excellency, please follow me."

The old scholar in charge of the library quickly led the way.

The seventh floor of the library houses the oldest books and maps.

Many of them are already infested with insects and worms, so they need to be handled with care.

However, Qin Xiao didn't need to flip through them; he simply scanned them with his divine sense and quickly identified several scrolls of bamboo slips and animal skin illustrations related to geographical changes and ancient legends.

After an incense stick has burned.

"This is it!"

At Qin Xiao's signal, Yu Fengling pulled out a roll from a pile of yellowed animal hides and excitedly unfolded it.

This is an extremely old map of mountains and rivers, drawn in a crude manner, and many place names are quite different from those of today.

In the northwest corner of the map, next to a range of mountains, are two small characters: Tiangong (天工).

Below it is a smaller note: "Ancient sacred sites of craftsmanship, producing many ingenious works, which later disappeared without a trace."

"Look at this location..."

Yu Fengling gestured to the name, "It's probably deep in the 'Wanhe Mountains' where the three kingdoms of Yu, Dayong, and Xiliang meet. The mountains there are steep and dangerous, and few people venture there. Only some herb gatherers and outlaws occasionally venture there."

Qin Xiao's gaze fell on the map, lost in thought.

Tiangong Valley, a sacred place for craftsmen, the Heavenly Craft Order...

"Husband, are you going here?" Yu Fengling asked.

"It might be worth exploring."

Qin Xiao put away the map. "However, there's no rush right now."

He has just broken through to the Nascent Soul stage, and his realm still needs to be consolidated.

With the Yu Kingdom newly established, Yu Qingyi needed time to reorganize the court.

The women in the harem also need time to consolidate their Foundation Establishment cultivation.

Tiangong Valley is located in a dangerous place at the junction of three kingdoms, and it is ancient, so its existence is still unknown.

"Let's return to Dayong first. Qingyi can handle things here."

Qin Xiao made a decision.

"good!"

Yu Fengling nodded.

It was dusk.

Inside the main hall of the Yu Kingdom, the lights were on.

Yu Qingyi has initially stabilized the political situation, and all the core members of Li Tianxiong's faction have been imprisoned, with implicated officials currently under investigation.

The scattered rebels were also reorganized and brought under control.

Upon seeing Qin Xiao and Yu Fengling return, Yu Qingyi dismissed everyone around her and rose to greet them: "Husband, Fengling."

"How did it go?"

Qin Xiao asked.

"The overall situation is settled; all that remains is a matter of trivial investigation."

Yu Qingyi's eyes shone brightly. "I am very grateful to my husband for his help this time. Otherwise, the Yu Kingdom would have been in great danger."

There's no need for thanks between us.

Qin Xiao waved his hand and handed the Heavenly Crafting Token and the ancient map to Yu Qingyi. "This was found in a secret room next to the royal treasury. Keep it; it might be useful in the future."

Yu Qingyi took the book and quickly glanced through it, a look of surprise flashing in her phoenix eyes: "Heavenly Craft Valley, there are indeed scattered records in the ancient royal books, saying it was the place where ancient craftsmen lived in seclusion, it's actually related to cultivating immortality?"

"There may be some remnants of the tradition."

Qin Xiao said, "However, there is no need to pay attention to it for now. Feng Ling and I will return to Dayong tomorrow. You stay here to reorganize Yu Kingdom. It will not be too late to return to the capital after the situation has completely stabilized."

Yu Qingyi pursed her lips, a hint of reluctance flashing in her eyes, but then nodded and said, "Qingyi understands. Qingyi will handle everything as soon as possible and return to reunite with her husband and sisters."

Her current ambition is to cultivate immortality, and worldly affairs are now a burden to her.

But some things still need to be understood, so that one's time as emperor will not have been in vain.

"Oh, right."

Yu Qingyi seemed to recall something, "Grand Tutor Lin and several high-ranking officials jointly requested an audience with my husband to express their deep gratitude in person..."

"No need."

Qin Xiao interrupted, "I will leave first thing tomorrow morning. There's no need to disturb anyone. Just remember to cultivate diligently and reach the Core Formation stage as soon as possible. As for the affairs of the Yu Kingdom, you can gradually delegate authority to reliable ministers. You don't need to do everything yourself."

"Yes, Qingyi will remember."

Yu Qingyi nodded solemnly.

That night, Yu Qingyi hosted a simple family banquet in the palace.

There were only three of them: Qin Xiao, Yu Fengling, and her.

During the meal, Yu Fengling chattered about what she had seen and heard that day, while Yu Qingyi listened quietly and occasionally served food to Qin Xiao, creating a warm atmosphere.

At dawn the next day, five-colored light quietly rose, leaving the Yu Kingdom's palace and speeding towards the Dayong Kingdom.

Yu Qingyi stood alone on the high steps in front of the palace, gazing at the horizon where the disappearing light had vanished.

After a long while, she turned and entered the main hall, her face regaining the cold and resolute expression of the Empress of Yu.

……

Da Yong, Zi Chen Palace.

When Qin Xiao and Yu Fengling returned, Luo Qingluan and the others gathered in the hall to wait for them.

"Welcome back, Your Majesty!"

The women bowed in unison, their faces filled with joy.

"Get up, everyone."

Qin Xiao's gaze swept over them, and seeing that the women's auras were stable and their cultivation had all improved, he nodded in satisfaction, "How is the palace?"

"Everything is fine."

Luo Qingluan reported in a gentle voice, "The sisters are cultivating diligently without any slackening. News came from President Mu that the two newly discovered small spirit mines have begun mining, and the first batch of spirit materials will be transported to the capital in three days. The cabinet is also becoming more and more proficient in handling government affairs, and there have been no major oversights."
