A mortal cultivating immortality can nurture spirit beasts.

Upon returning to Huangfeng Valley Market, Lin He summoned two people, one of whom immediately arranged for Xin Ruyin and Xiao Mei to stay.

Dong Xuan'er looked at Xin Ruyin and Xiao Mei with some curiosity, guessing their relationship with Lin Hedi. However, she noticed that although Xin Ruyin had a good temperament, her appearance was ordinary, so she didn't care.

The other person took the materials list given by Hong Fu and went to help collect the materials. Soon, only Lin He, Dong Xuan'er and Hong Fu were left.

Hong Fu casually conjured a soundproof barrier before saying, "Alright, now that there's no one else around, take that thing out."

Lin He naturally did not hesitate and took out two 500-year-old Jade Spirit Flowers. He had very few spiritual herbs left in his hands because he had used them to refine Foundation Establishment Pills and Youth Preservation Pills. Apart from the Thousand-Year Ice Spirit Flower that he had reserved, he only had two 500-year-old spiritual herbs left. Now, in order to exchange for cultivation techniques, he took them out.

"There are actually two Jade Spirit Flowers!"

Hong Fu, who usually had a cold expression, couldn't help but show joy when she saw two five-hundred-year-old spiritual herbs. She needed two seven- or eight-hundred-year-old spiritual herbs to refine pills. She had been searching for them for a long time without success. Although these two were only five hundred years old and their medicinal effects were somewhat weaker, they were still usable.

"To be honest, my nephew got himself into trouble because of these two spiritual herbs and almost didn't make it back. He spent most of his spirit stones on them to buy them."

Seeing Lin He's pitiful appearance, Hong Fu understood his meaning perfectly and quickly said, "I need these two spiritual herbs. Please feel free to ask for anything, my junior brother."

"My junior disciple has been searching for a cultivation method for a long time, but to no avail, so..."

"What kind of spiritual root does my junior disciple possess?"

"Dual spiritual roots of metal and fire."

"I see. Wait a minute." Hearing the words "cultivation technique," Hong Fu showed no surprise. She swept her hand across the table, and five or six jade slips appeared. "Choose one yourself. We can discuss the transaction after you've chosen one."

Lin He was excited upon seeing this. He wasn't faking it; the Golden Light Technique he was currently cultivating was far too ordinary, and he had long wanted to change his cultivation method.

"The Gilded Gold Technique? The Taiyang Technique?"

Lin He flipped through several jade slips, but he wasn't very satisfied with any of them. It wasn't that these cultivation techniques were bad, but rather that they were either good at fighting but slow to cultivate, or they were fast to cultivate but didn't have any powerful spells. In short, they couldn't do both.

Lin He flipped through the jade slips for a while without finding one. When it came to the fifth slip, he had already given up hope, thinking he'd just pick one to use as a temporary measure. However, after seeing the contents of the jade slip, his heart trembled with immense joy, but his face displayed an extremely ugly expression.

"Senior Uncle, isn't the cultivation technique recorded on this jade slip far too difficult to practice?"

Hong Fu also noticed the jade slip and sighed, "This cultivation technique was actually quite famous hundreds of years ago. Have you ever heard of the name Jin Yuan Sanren, my junior disciple?"

"Jin Yuan Sanren?" Lin He's heart skipped a beat upon hearing this, but he shook his head.

"This Golden Essence Hermit is a mid-Nascent Soul cultivator. He appeared out of nowhere, seemingly out of nowhere, and is said to be unlike any cultivator from our Southern Continent. The reason he is so famous is because of his extraordinary age. It is said that he successfully condensed his Nascent Soul at the age of two hundred. Such talent is truly rare in the world. The cultivation technique he practices is this Star Refining Golden Essence Technique!"

"To reach the Nascent Soul stage at two hundred years old?" Dong Xuan'er, standing to the side, was taken aback upon hearing this, clearly quite surprised.

At this point, Hong Fu put on a strange expression and said, "It is said that he was very handsome, but he was extremely lustful. The reason he disappeared without a trace is because of this. It is said that after he formed his Nascent Soul, he still tried to find female Nascent Soul cultivators, which angered several large sects. These large sects joined forces and sent seven or eight Nascent Soul cultivators to severely injure him. After that, he disappeared without a trace and has probably already passed away."

After hearing this story, Dong Xuan'er blushed slightly, never expecting that a high and mighty Nascent Soul cultivator could be so eager.

Lin He, however, sensed a different meaning and thought to himself,

"It seems that this Jin Yuan Sanren knows the secret technique of dual cultivation. He hoped to break through the bottleneck and enter the late stage of the Nascent Soul stage through dual cultivation, but the result was the opposite and brought disaster upon himself."

Thinking of this, Lin He subconsciously touched his storage bag. He still had a token in his storage bag, which was said to be able to obtain additional treasures after entering the remains of this Jin Yuan Sanren.

Lin He suddenly said, "I understand the story of Jin Yuan Sanren, but isn't the Star Refining Golden Yuan Technique a bit too difficult to cultivate?"

This jade slip contains an incomplete cultivation technique, which can only be cultivated up to the seventh level, which is the early stage of Core Formation.

That's not all. The key is that, apart from the first three levels being easy to cultivate, the fourth level requires drawing upon star power to temper the body. Not only that, but it also requires preparing a corresponding body-tempering elixir to assist in cultivation. And the main ingredient of this body-tempering elixir is actually a level-five demon core.

Hong Fu nodded and said, "This technique is not only good for killing, but it is also said that practitioners can temper their spiritual power, cleanse their bodies, and strengthen their physique. However, when cultivating by drawing upon the power of the stars, one cannot set up any arrays or restrictions, because this will hinder the tempering of the body by the star power. This is like being a sitting duck. If one encounters someone with ulterior motives, there may be big trouble."

"How did Jin Yuan Sanren cultivate?" Dong Xuan'er, who was standing to the side, seized on the key point, and Hong Fu had no choice but to explain.

"Jin Yuan Sanren had another extraordinary encounter. It is said that he obtained a star map in his early years. He did not need to rely on the power of the stars in the sky to cultivate. As long as he carried the star map, he could cultivate even in his cave."

"So that's how it is."

Dong Xuan'er felt a pang of envy; the Star Chart was clearly an extraordinary treasure.

Lin He was thrilled to hear this. Although he did not have a star map, his personal space was filled with starlight, and the place was very safe, so he was not afraid of being ambushed while cultivating.

As for the level-five demon core, it is extremely rare for others, especially for cultivators from Tiannan, but it is not a problem for Lin He.

It can be said that this technique was tailor-made for him and is the most suitable technique for him to cultivate. Moreover, this technique is a metal-element technique, and metal energy is associated with killing and destruction, which adds to its power.

Lin He was already trying to figure out how to get his hands on the cultivation technique, while Hong Fu was trying to persuade him to give up. But how could Lin He listen? He shook his head and said...

"Thank you for the reminder, Senior Uncle. However, I am somewhat interested in this body-strengthening technique. Although I cannot cultivate it, I can still use it as a reference, which is of some value to me."

Seeing Lin He's insistence, Hong Fu didn't say anything more. This cultivation technique had been in her possession for a long time, and she had never been able to exchange it. Now that Lin He wanted it, she naturally wouldn't refuse.

However, the value of this incomplete cultivation technique was certainly not enough to exchange for two spirit herbs. After thinking for a moment, Hong Fu still took out seven or eight items. "This cultivation technique is indeed not worth that many spirit stones. I will not let my junior nephew suffer a loss. You can choose three items from these."

Although this Senior Sister Hong Fu had a bad temper, she wasn't as stingy as Li Huayuan. Lin He nodded to himself in approval. He began to examine these items, and one of them actually contained records of various strange spirit beast formations. When Lin He examined the other two items, he couldn't help but be surprised.

"This is... a pill formula? Or a formula for Foundation Establishment stage cultivators?"
