Han Li scanned the opening lines of text in the jade slip back and forth several times with his spiritual sense, then carefully scanned the restriction covering the content behind it before quickly withdrawing his spiritual sense.

Although he didn't know what this restriction was, based on his years of research into various restrictions, he could sense that this restriction was definitely not simple. If he ever had the idea of forcibly breaking it, the jade slip would probably collapse on its own before he could crack it, and his own spiritual sense would probably be affected and damaged.

Han Li waved his hand and sent the gray jade slip back to Jiao San's side, saying, "Fellow Daoist Jiao San, since we are all understanding people, please speak frankly. What conditions do you want in exchange for telling me this cultivation method?"

Jiao San seemed to smile beneath his mask, placing the jade slip on the stone table beside him, and asked, "Fellow Daoist He Shiyi, before we discuss this matter, I have one more thing I would like to ask you."

"Fellow Daoist, please feel free to ask," Han Li said, slightly surprised.

"How much do you know about the Refining Spirit Technique?" Jiao San asked calmly.

Jiao San's question was completely beyond Han Li's expectations. He was stunned for a moment, pondered slightly, and then said, "As far as I know, the Refining Spirit Technique is a forbidden technique in the Immortal World. Although it can enhance spiritual power, most people who practice this technique become mad and bloodthirsty, causing harm to the world and leading to great chaos in the Immortal World. Therefore, it is not tolerated by the major immortal domains, and each immortal palace strictly prohibits anyone from practicing it."

"Oh, is that all?" Jiao San asked slowly.

"That's roughly all I know. Is there anything wrong with what I said?" Han Li thought for a moment and asked.

"These are all the most basic understandings of the Refining Spirit Technique. If I'm not mistaken, Fellow Daoist He Shiyi's Refining Spirit Technique has already reached the third level, right? I wonder who taught it to you? Did that person not tell you about the Refining Spirit Technique in detail at the time?" Jiao San shook his head and asked again.

"I accidentally obtained the first half of the Refining Spirit Technique's secret formula by chance many years ago. At that time, I didn't know this technique had so many taboos, so I groped my way to cultivating it to this day," Han Li said, the figure of He Kang from the Spirit World appearing in his mind, but naturally he wouldn't mention this matter, only replying.

He wasn't exactly lying, He Kang didn't tell him anything about the Refining Spirit Technique at the time, he only taught him the third level secret formula of the Refining Spirit Technique.

"Fellow Daoist cultivated the Refining Spirit Technique to its current state without any guidance, relying solely on independent exploration!" Jiao San's body seemed to shake slightly, and a strange light flashed in his eyes.

"Is there a problem?" Han Li asked, frowning.

"No, Fellow Daoist is truly a genius, I admire you," Jiao San looked Han Li up and down again, took a light breath, and said, word by word.

"You flatter me, it's just a coincidence," Han Li said lightly.

"Since Fellow Daoist doesn't know much about the Refining Spirit Technique, then I'll start from the beginning, otherwise the subsequent matters will be difficult to discuss," Jiao San said again.

"I'm all ears," Han Li said, his eyes flashing with a hint of curiosity.

He was indeed very interested in the origin of the Refining Spirit Technique.

"What Fellow Daoist He Shiyi just said is basically true. Although the Refining Spirit Technique has great drawbacks, its power is also extremely great, and it was once very famous in the Immortal World. However, the reason why this technique is listed as a forbidden technique, in addition to the fact that this technique is difficult to cultivate, and most practitioners eventually become mad and bloodthirsty, is also because the Refining Spirit Technique is a cultivation method that was spread from the Reincarnation Hall." Jiao San spoke eloquently, his tone clearly emphasizing the three words "Reincarnation Hall."

"Reincarnation Hall!" Han Li was taken aback.

"Oh, it seems Fellow Daoist He Shiyi knows about the Reincarnation Hall, that's good," Jiao San said, somewhat surprised, then smiled.

"I dare not say, I have only heard some things about the Reincarnation Hall, Fellow Daoist Jiao San, please continue," Han Li waved his hand and said.

"Since Fellow Daoist has heard of the Reincarnation Hall, you should also know that it is an adversarial relationship with the major immortal palaces. Nowadays, anyone who practices the Refining Spirit Technique is more or less related to the Reincarnation Hall, which is why they are being so strictly hunted down," Jiao San nodded and continued.

"That's right, I have indeed heard of it," Han Li nodded slowly upon hearing this, and the figures of Baili Yan, the First Dao Lord of the Candle Dragon Dao, and Old Taoist Huyan flashed in his mind.

"The Refining Spirit Technique is rumored to have been created by the founding ancestor of the Reincarnation Hall, and has always been a symbol of the Reincarnation Hall in the Immortal World. However, for some reason many thousands of years ago, the first half of this cultivation method was spread out, and the second half of the Refining Spirit Technique is now only in the hands of the Reincarnation Hall. Moreover, because the first half of the cultivation method was spread out, the Reincarnation Hall is extremely strict in guarding the second half of the cultivation method, and it is not allowed to be taught to anyone who is not a member of the Reincarnation Hall," Jiao San said slowly, looking at Han Li with profound meaning in his eyes.

Han Li and Jiao San looked at each other, and asked, "Fellow Daoist Jiao San holds the Refining Spirit Technique, could it be that you are also a member of the Reincarnation Hall?"

"That's right," Jiao San nodded.

Han Li raised his eyebrows, somewhat surprised in his heart.

He knew Jiao San's identity very well, he should be an important figure in the Everchanging Alliance, but he didn't expect that he would now transform into a member of the Reincarnation Hall.

Although it was common for people from major sects to join the Everchanging Alliance, they would only become ordinary members at most, just like him.

Jiao San held a high position in the Everchanging Alliance, and was still a member of the Reincarnation Hall, which was a bit intriguing.

"Fellow Daoist He Shiyi, if you want the second half of the Refining Spirit Technique, if it is difficult, it is indeed very difficult, but if it is easy, it is also very easy," Jiao San continued.

"You are..." Han Li was slightly stunned.

"That's right, as long as you are willing to join my Reincarnation Hall, I will immediately offer this jade slip with both hands," Jiao San said directly.

Han Li tapped the tea table beside him lightly with his fingers, and fell silent.

Jiao San didn't urge him, and sat quietly on the side.

At this moment, a sound of footsteps came, and it was a servant, holding a tray in his hand with two cups of spiritual tea on it.

The teacups were crystal clear, made of some unknown material. The spiritual tea in the cups was also extremely extraordinary. Although not much tea fragrance was emitted, wisps of white mist constantly overflowed from the teacups, and condensed into the shape of several cranes, hovering around the teacups for a week before slowly dissipating.

"Hehe, Fellow Daoist He Shiyi has been here for so long, but I haven't served you tea, it's really rude. This is a special White Mist Spiritual Tea unique to our Reincarnation Hall, it's quite good, please have a taste," Jiao San glanced at the spiritual tea on the tray and said with a smile.

The servant placed the teacups beside the two of them and quickly retreated.

Han Li was thinking about things and didn't pay attention to the spiritual tea beside him. Hearing Jiao San's words, he looked at the teacup beside him, a look of surprise on his face.

These white mists were not ordinary water vapor, but immortal spiritual energy that was extremely rich, and could actually condense into a shape automatically, this kind of spiritual tea was really extraordinary.

Han Li's eyes flickered, the immortal spiritual power contained in this cup of spiritual tea was probably equivalent to a month of his cultivation.

Such spiritual tea could be called a celestial product.

However, he didn't have the habit of drinking tea casually in unfamiliar places. Although he was quite tempted, he didn't touch the teacup.

Seeing Han Li so cautious, Jiao San smiled faintly, and picked up the teacup and tasted it on his own.

Han Li sat silently on the side, his face looked calm, but his heart was turbulent.

The matter of the Candle Dragon Dao had left a very deep impression in his heart. The First Dao Lord Baili Yan had already reached the half-step Grand Yi realm, and his status and prestige in the Candle Dragon Dao were extremely high, but because he was a member of the Reincarnation Hall, he was immediately betrayed by most of the Golden Immortal Dao Lords, and jointly strangled by the Northern Cold Immortal Palace.

Old Taoist Huyan was also obviously involved with this Reincarnation Hall, and in order to protect Baili Yan, his life and death were now unknown.

Han Li didn't know much about this mysterious organization of the Reincarnation Hall, but he was very clear that the Northern Cold Immortal Palace, and even the so-called "Court," were very hostile to this force.

Although he was now being hunted down by the people of the Northern Cold Immortal Palace because of Tao Yu's matter, he was actually unwilling to join this Reincarnation Hall and completely stand on the opposite side of the various immortal palaces.

This was tantamount to asking for trouble for him, who was not very powerful at the moment.

But if he didn't join the Reincarnation Hall, he wouldn't be able to obtain the follow-up cultivation methods of the Refining Spirit Technique, and he would face the risk of falling into madness in the future.

Han Li hesitated in his heart, and didn't speak for a long time.

Seeing that Han Li hadn't spoken for a long time, Jiao San's eyes flickered, and he put down the teacup and said, "Is Fellow Daoist worried that after joining my Reincarnation Hall, you will have to directly become enemies with the Northern Cold Immortal Palace?"

"That's right," Han Li didn't shy away and said directly.

"Haha, Fellow Daoist He Shiyi must have lived in the Black Wind Sea for a long time and doesn't know much about the outside world. Although the Northern Cold Immortal Palace is powerful, it can't dominate the world alone. The forces that can compete with it are not just my Reincarnation Hall alone, they just haven't stood up until the critical moment. Moreover, my Reincarnation Hall is in the dark, and the Northern Cold Immortal Palace is in the light. It's not easy to find us," Jiao San said with a chuckle.

"You've said so much, but what proof do you have? I can't just completely believe you because of what you said!" Han Li asked solemnly.

"You will eventually find out whether what I said is true in the future. Moreover, you are carrying the three levels of the Refining Spirit Technique. Once it is detected by the immortal palace, you will be treated as a member of the Reincarnation Hall anyway. And according to my observation, Fellow Daoist probably had a backlash crisis not long ago, right? If you can't cultivate the follow-up Refining Spirit Technique in time, I'm afraid the next time..." Jiao San said meaningfully.

Han Li's heart trembled upon hearing this.

He had already tried his best to restrain the power of his spiritual sense in his mind, but he didn't expect that the other party would still detect the abnormality of his spiritual sense.

Han Li continued to tap the tea table with his fingers, the various thoughts in his mind were spinning non-stop, and his eyes gradually became firm.

Seeing this scene, Jiao San knew that Han Li was gradually being moved by him, and continued, "Fellow Daoist He Shiyi, it's not that I'm boasting, our Reincarnation Hall has a profound foundation. In addition to the fact that our power is not inferior to the Northern Cold Immortal Palace, we have all kinds of elixirs, materials, secret techniques and cultivation methods, which will definitely help Fellow Daoist's cultivation. Moreover, our invitation to Fellow Daoist He Shiyi to join the Reincarnation Hall is not to let you be a member of the Reincarnation Hall, but to invite you to serve as the 'Child of Reincarnation' of my Reincarnation Hall."
