Profound Sun Dao cultivation emphasizes inner cultivation of Yang Spirit, external pure Yin, and focusing on Yin Yang balance.

This Yin and Yang does not refer to male and female, but rather to Yin Yang Qi. However, many cultivators, in seeking shortcuts, often prefer Yin Yang dual cultivation between men and women.

If it is a mutual complement between men and women, it can be considered the righteous path of cultivation. However, if one party acts as a furnace for spirit refinement, it is a lower and minor path.

Most people prefer shortcuts. Especially those among the nobility and wealthy, who cannot endure loneliness. The art of Yin Yang harvesting that drains oneself while benefiting others, yet also offers pleasure, is practically tailor-made for them as a cultivation method.

Yuan Buyin recognized this and vigorously promoted the method of dual cultivation, immediately attracting a large number of noble followers.

Yuan Buyin himself does not care much about it. His success as a Spirit Immortal relied on personal talent, not on taking such opportunistic shortcuts.

However, after passing the Eight Tribulations, Yuan Buyin found it challenging to improve his Dao practice, no matter how he cultivated.

He also understood that his innate talent had reached its limit, making it nearly impossible to break through using his own power.

Passing the Nine Tribulations would make one a Human Immortal, an entirely different level from a Spirit Immortal.

Yuan Buyin was just one step away, and he was certainly unwilling to be stuck at the threshold of the Nine Tribulations.

Moreover, passing Tier Nine would greatly extend one's lifespan. Employing various methods for avoiding the tribulation, living an additional two to three thousand years would not be difficult.

Even if it were just for immortality, all means must be used to pass the Nine Tribulations.

Limited by his own innate talent, Yuan Buyin could only rely on external forces for cultivation. Although harvesting Yin and replenishing Yang is a minor path, as long as it works, it suffices.

However, for a Spirit Immortal, the choice of target for harvesting Yin and replenishing Yang is critical. It's not enough to find just any young girl.

Profound Sun Dao is a legitimate Daoist sect and wouldn't stoop to kidnapping women.

Under his tacit approval, Qingyi Tower's influence grew unchecked and ever more brazen. Its power spread across Great Wind Country, conspiring with various gangs and factions to build a vast network.

Such a massive scale allowed Yuan Buyin to find several high-quality furnaces. Consuming the ultimate Yin Qi from thousands of women, his cultivation greatly increased.

Once these thousands of women had their ultimate Yin Qi drained, their life force was completely extracted. Even if they didn't die immediately, they would rapidly age into elders and die of old age within days. 𝐟𝕣𝗲𝕖𝕨𝗲𝐛𝗻𝗼𝐯𝗲𝚕.𝗰𝚘𝐦

Yuan Buyin didn't care about the women's lives, but at his cultivation bottleneck, he needed even higher-quality furnaces.

While many women possess ultimate Yin Qi, their quality varies in multiple levels. The highest quality is the Pure Yin Body.

Yuan Buyin now sought a Pure Yin Body as a furnace to break through his cultivation bottleneck.

Thus, upon hearing Boss Huang mention a Pure Yin Body, Yuan Buyin's interest was immediately piqued.

He didn't care who the other party was; as long as it was a Pure Yin Body, he wouldn't miss it.

Moreover, the strongest in Great Wind Country is Xuan Xiang. Celestial Dragon Temple clearly does not have female cultivators. As long as they aren't from Celestial Dragon Temple, Yuan Buyin couldn't care less.

Note that the entire Northern Province has merely a dozen Human Immortal level experts. According to Boss Huang, this pair of young men and women didn't match any known Human Immortal powers.

Of course, they could be disciples of a Human Immortal. However, in Great Wind Country, a disciple of a Human Immortal is nothing. Even if a Human Immortal personally arrived, they wouldn't dare act recklessly in Yong'an City.

Yong'an City has a heritage of tens of thousands of years, and its city defense array has been fortified and strengthened over a long time, capable of restraining Human Immortals with ease.

Yuan Buyin had ample confidence, caring little about anyone's identity. Waving a duster, he stood up, "Let's go find those two juniors. I, the humble Daoist, will avenge you."

Boss Huang's fuzzy face showed a gleam of joy. With Yuan Buyin taking action, the adulterous couple had nowhere to escape. Once in his grasp, he'd make them suffer.

As man and demon were about to exit, a flash of azure light at the door revealed a Daoist.

The Daoist had a handsome look, dressed in a golden dragon-embroidered Daoist robe, resembling the dragon robe of an emperor. This luxurious and extravagant robe suited him well.

Boss Huang hastily cupped his hands in salute, "Greetings, Imperial Tutor."

This Daoist named Li Yuncang is from the royal family of Great Wind Country and is a Six Tribulation Spirit Immortal. Nearing four thousand years old, he is also the guardian of the royal family and tutor to each emperor, respectfully addressed as Imperial Tutor.

However, this Imperial Tutor's character, charitably described as romantic, is frankly lecherous. Abusing his divine techniques, he corrupted the palace, filling it with debauchery.

Given Li Yuncang's power, acquiring beauties was effortless. Yet, his nature was innately evil, delighting in nefarious deeds. Qingyi Tower was likely his creation, later handed to Boss Huang and Qing Xiaoyi for management.

After all, as an Imperial Tutor, even in wickedness, discretion was necessary.

Li Yuncang suddenly appeared, sensing the strong agitation of primordial Qi within Yong'an City, coming over to inquire about the situation from Yuan Buyin.

Li Yuncang ignored Boss Huang and instead greeted Yuan Buyin with a bow, "Dao Brother, I, the humble Daoist, arrived rudely."

Curiously he asked, "Where is Dao Brother heading? What has happened?"

"Someone has destroyed Qingyi Tower, and Qing Xiaoyi has been killed."

Yuan Buyin replied indifferently, "I'm going to see what happened."

Yuan Buyin didn't think much of Li Yuncang, as he did wicked deeds for progressing his Dao practice, whereas Li Yuncang did them purely out of malice.

However, this figure wielded significant influence both within the court and had considerable cultivation power, so Yuan Buyin remained courteous to him.

"Qing Xiaoyi has been killed?"

Li Yuncang's handsome face showed a hint of regret, "That snake demoness's slender waist was quite entertaining, a unique delight, a pity."

He pondered and then added, "A snake demon that's lived for thousands of years would make a very nutritious broth."
