Burial Furnace

At noon, Hua Nongying warmly entertained Zhang Yuan at the cave dwelling.

Various spiritual fruits were laid out on the table, including bright red vermilion fruits, glistening purple grapes, and golden peaches, each one containing rich spiritual energy.

The beverage is also a spiritual fruit juice; drinking it makes your mouth feel refreshed, and spiritual energy flows through your body.

Fine wine is also a spirit wine, mellow and long-lasting, with an endless aftertaste.

Zhang Yuan ate to his heart's content and drank to his heart's content.

He finally gained a deep understanding of the Hehuan Sect.

They certainly wouldn't intentionally harm anyone.

But if targeted, they will retaliate without hesitation and show no mercy.

After a satisfying meal, it was already afternoon.

Zhang Yuan stood up and bid farewell to Hua Nongying.

Hua Nongying did not try to stop her, but instead summoned the white crane.

"Little White, take him back." She gently patted the white crane's head.

Bai He nodded, walked up to Zhang Yuan, squatted down, and gestured for him to sit down.

Zhang Yuan hesitated for a moment, then climbed onto the crane's back and hugged the white crane's neck.

The white crane stood up, spread its wings, and took flight.

Zhang Yuan looked back and saw Hua Nongying standing in the valley, watching him leave. She looked somewhat lonely and forlorn.

The white crane flies very fast, but very steadily.

Zhang Yuan hugged its neck, feeling the whistling wind in his ears, but his heart remained unsettled for a long time.

Hua Nongying did not harm him.

She really just invited him over, had a philosophical discussion with him, and then safely sent him back.

She is a good person.

A strange impulse welled up in Zhang Yuan's heart.

He patted the white crane's neck and shouted, "Little White, go back! Rejoin Huan Sect!"

The white crane paused for a moment, then let out a clear cry, turned around, and flew towards the Hehuan Sect.

When the white crane landed in front of Baihua Residence, Hua Nongying was standing at the door, preparing to return to her cave.

She saw Zhang Yuan return, and a hint of surprise flashed in her eyes.

"Why are you back?"

Zhang Yuan jumped off the crane's back, walked up to her, took a deep breath, and said, "Senior, I would like to try cultivating with you."

Hua Nongying was stunned.

She looked into Zhang Yuan's earnest eyes, remained silent for a moment, and then a smile slowly appeared on her lips.

That smile was like spring flowers in bloom, like the moon shining brightly.

"it is good."

She took Zhang Yuan's hand and led him into the secret cultivation chamber of the cave.

The secret room was not large, and its four walls were as smooth as a mirror, gleaming with a faint bluish light.

The floor was covered with a soft carpet that emitted a faint scent of grass and wood.

The walls were inlaid with some luminous pearls, which provided a soft light.

It was extremely quiet.

"I have indeed mastered the Yin-Yang Rejuvenation Technique," Zhang Yuan said, looking at Hua Nongying. "But I still want to see the Yin-Yang Harmony Technique."

Hua Nongying's eyes lit up instantly, like two stars suddenly ignited in the night sky.

Without asking any further questions or hesitating, she took out a jade slip from her spatial ring and handed it to Zhang Yuan.

"You go out first, I need to think about it carefully," Zhang Yuan said.

Without saying a word, Hua Nongying turned and walked out.

Zhang Yuan sat down cross-legged.

With a thought, he tossed the jade slip into the Immortal Transformation Furnace in his dantian. The dark golden flames gently swirled around it and engulfed it.

There was no smoke, no ash, only a wisp of pure primordial power overflowing from the furnace and merging into Zhang Yuan's limbs and bones.

His lifespan was extended by three days.

At the same time, a massive amount of information flooded into his mind like a tidal wave—the entire contents of the Yin-Yang Harmony Technique, from Qi Refining to Foundation Establishment, from Foundation Establishment to Golden Core, from Golden Core to Nascent Soul, and even higher realms. The cultivation methods, true essence circulation paths, and precautions for each stage were clearly imprinted in his mind.

He closed his eyes, carefully processing this information.

It's much simpler than the "Yin Yang Rejuvenation Technique".

It is indeed a water-attribute cultivation technique suitable for female practitioners, especially those with water-elemental roots. Its core lies in the flow and circulation of yin-attribute true essence.

The creator of this cultivation method was a female predecessor from more than two thousand years ago, who was also a genius with exceptional talent. She cultivated all the way to the Mahayana stage using this method and ascended to heaven.

The foundation of the technique is very solid, and the flow path of true essence is also designed in an extremely ingenious way.

However, the problem is that this exercise has a fatal flaw—isolated yin cannot grow.

Although a woman can make progress by practicing alone, the speed is extremely slow.

Like a small river, if the flow is too small, no matter how much you dig the channel deeper, it will be difficult to become a great river.

To solve this problem, the senior left a shortcut in the technique—to use the power of a man to harmonize yin and yang.

Specifically, it involves the man and woman placing their hands together, allowing their vital energy to circulate within their bodies.

When a man's yang energy and a woman's yin energy intertwine, forming a yin-yang convergence, the speed of cultivation will greatly accelerate.

That sounds beautiful.

But the drawbacks are too great.

When the two types of true energy circulate in the body, they will inevitably mix together.

After cultivation, the true essence returns to the dantian, but the amount may not be the same as before cultivation.

Sometimes there are more women, sometimes there are more men.

If both sides are selfish, they will inevitably clash over this small gain or loss.

Moreover, the technique also records a secret method of absorbing male essence and vital energy—it can forcibly devour a man's yang energy and true essence at an extremely fast speed with astonishing effects.

But the cost is equally staggering.

The true essence obtained through sexual intercourse is impure and unstable.

Moreover, this method is too insidious and cannot be tolerated by Heaven. When undergoing the Heavenly Tribulation, the lightning tribulation will be several times more terrifying than that of ordinary cultivators, almost guaranteeing their survival.

In comparison, the Yin-Yang Rejuvenation Manual is simply flawless.

This cultivation method is based on the Five Elements and is suitable for cultivators with Five Elements spiritual roots.

Moreover, it is a dual cultivation technique, completely integrating yin and yang for mutual benefit and complementarity.

It must be guided by a cultivator with the five elements spiritual roots, so that the true essence circulates within the male and female bodies.

During cultivation, true qi will become pure.

The speed of converting spiritual energy will be greatly increased.

After each cultivation session, each person's true essence will automatically separate and return to their respective dantian, and each essence will be strengthened.

More importantly, this practice does not involve any concept of "replenishing the body through sustenance."

Open and aboveboard, upright and honorable.

Zhang Yuan tapped his fingers lightly on his knees as his mind raced.

If I and they cultivate the "Yin Yang Rejuvenation Technique" together, helping them purify their true essence, and then they cultivate the "Yin Yang Harmony Technique" separately, their progress will be much faster.

Each time they break through a new realm, I will help them refine their cultivation once more, so that their cultivation speed will be no less than that of the disciples of those major sects.

With this in mind, Zhang Yuan made a plan.

He got up and opened the stone door. He waved to Hua Nongying, who was waiting outside.

Hua Nongying entered, bringing with her a rich fragrance.

"I can cultivate the Yin-Yang Rejuvenation Technique with you," Zhang Yuan said bluntly, "but I have a few conditions."

"First, from now on, the Yin-Yang Harmony Technique will be renamed the Jade Maiden Heart Sutra, and the Harmony Sect will be renamed the Jade Maiden Sect."

Hua Nongying paused slightly, then nodded: "Okay."
