A mortal cultivating immortality can nurture spirit beasts.

Lin He was not surprised at all. He activated his divine sense, and a jade mantis at the peak of level one flew over. Immediately afterwards, a system notification appeared.

"A level one peak-level demonic beast, the Jade Mantis, has been detected. Do you wish to consume a mid-grade spirit stone to cultivate it to level two?"

Lin He took out the three mid-grade spirit stones he had just obtained and selected a mid-grade earth-attribute spirit stone to embed into the groove.

The next moment, the Jade Mantis was sucked into the sky by a tremendous force. A drop of spiritual liquid dripped down the funnel onto the Jade Mantis's body. The spiritual liquid, containing immense spiritual power, began to seep into its body. Soon, the Jade Mantis's aura surged, climbing from the peak of level one to level two.

The suction force in the air disappeared, and the Jade Mantis moved in a flash, flying more than ten feet away in the blink of an eye, its speed was unbelievable.

"As expected of the Jade Mantis, it's incredibly fast."

Lin He's current specialty is manipulating spirit beasts to overwhelm the few with the many. Naturally, he has read many books about demonic beasts and consulted some fellow disciples who are skilled at manipulating spirit beasts, thus gaining a lot of information that he did not know before.

For example, monsters like the Icefire Wolf, the Three-Eyed Fire Wolf, and the Azure Water Crocodile rank quite high among low-level monsters and are very powerful.

However, once it was promoted to level two, there was no dramatic change; instead, its overall evaluation dropped considerably.

Among the level two to four demonic beasts, Lin He selected three of the most promising ones to serve as his bodyguards and henchmen: the Golden Python, the Jade Mantis, and the Jade-Eyed Toad.

At this moment, he was preparing to continue nurturing the Jade Mantis. Looking at the two remaining drops of spiritual liquid at the top of the funnel, he took out another mid-grade spirit stone and embedded it in. After doing this twice, he finally managed to advance the Jade Mantis to level four, and its strength was equivalent to that of a late-stage Foundation Establishment cultivator.

The system notification sounded again at this moment.

"Friendly reminder: It takes ten mid-grade spirit stones to nurture a level five spirit beast?"

"A level four demonic beast, the Jade Mantis, has been detected. Should we consume ten mid-grade spirit stones to upgrade it to level five?"

"Ten mid-grade spirit stones?"

Lin He was stunned for a moment before his brows furrowed. "One induction session costs ten mid-grade spirit stones? At this rate, I won't have enough spirit stones to last."

Lin He's original idea was simple: with his nurturing system, he didn't need spirit herbs that were three or four hundred years old. He could use level five demon cores as the main material to refine pills that could improve his Foundation Establishment cultivation.

However, the system's price now exceeds his expectations.

"Without a large number of level 5 demon cores, I cannot refine a large number of pills to improve my cultivation, nor can I advance quickly. It seems that I need to obtain a large number of mid-grade spirit stones."

"It's a pity that there's no Biling Island in Tiannan. There are plenty of high-grade spirit stones there, not to mention mid-grade spirit stones. However, materials from level 5 demon beasts should be very valuable in Tiannan, so it's not impossible to earn a lot of mid-grade spirit stones."

With this in mind, Lin He's thinking broadened even further. "That's right, as long as we can find stable sales channels, we won't have to worry about not having mid-grade spirit stones."

With this in mind, ideas began to pop into Lin He's head.

Three days later

Lin He had just gotten up when he heard a series of crackling sounds outside his cave. He quickly ran out of the cave and saw a beautiful figure next to his cave directing a high-grade blue flying sword to open up the cave. It was Senior Sister Chen.

"Oh, you're back. Did you finish your business so quickly?"

Seeing that Senior Sister Chen was busy controlling the flying sword magic weapon, Lin He naturally couldn't let Senior Sister Chen do the work alone, so he also took out a top-grade flying sword from his storage bag to help open up the cave.

This top-tier flying sword, obtained from Feng Yue, was indeed formidable, far surpassing Senior Sister Chen's superior-grade flying sword. With Lin He's assistance, the speed of opening the cave dwelling increased significantly. Senior Sister Chen, drenched in sweat, was extremely excited and exclaimed...

"I was lucky, things went very smoothly, and I just happened to arrive in time. When I arrived, my elder brother hadn't left home yet. He was overjoyed to hear that I had Foundation Establishment Pills. He has now gone into seclusion again, and according to him, the chances of success this time are at least 80%."

After finishing speaking, Senior Sister Chen handed him two exquisite storage bags, smiling brightly as she said, "These are filled with quite a few mid-grade spirit stones, including that pill, as well as the income from selling various magical artifacts before."

Lin He took it and probed it with his divine sense. He was overjoyed to find that there were a total of 110 mid-grade spirit stones inside. This was the first time Lin He had ever received such a large sum of money, and he felt like he had become rich overnight.

With his cultivation level at the early stage of Foundation Establishment, having this kind of wealth already makes him a small-time tycoon.

In high spirits, the two worked together and successfully carved out a cave dwelling in just half a day.

After reaching the Foundation Establishment stage, Senior Sister Chen clearly became much more proactive. She directly pulled Lin He into the cave, and the two sat down on the bed.

Before Lin He could even ask, Senior Sister Chen proactively informed him, "Those high-grade, mid-grade, and low-grade magic artifacts sold for over ten thousand spirit stones. After deducting the 20% handling fee, there were still eight thousand spirit stones left. The price of the Foundation Establishment Pill was a matter of much debate; some said two thousand, some said three thousand. I negotiated with my elder brother at three thousand, and to my surprise, he didn't even try to bargain and agreed immediately."

Lin He smiled. As the eldest son of the Chen family, Chen Qiaoshan had always wanted to establish his foundation. Being able to buy a Foundation Establishment Pill for three thousand spirit stones, this senior brother Chen was probably still grinning from ear to ear. He wouldn't be bothered to haggle over the price.

Lin He stopped thinking about it and instead looked at the two exceptionally exquisite storage bags, then asked,

"This storage bag has at least thirty times the capacity, it must be expensive."

Senior Sister Chen smiled and said, "I noticed you usually carry around the ten-times storage bag that was given to you when you first entered the sect. How can that be? My older brother really likes these two storage bags. He only took them out because I insisted."

"Senior Brother Chen is still your elder brother, isn't this considered siding with outsiders?"

Hearing this, Lin He couldn't help but tease her, and Senior Sister Chen, upon hearing this, couldn't help but puff out her cheeks in annoyance.

"What do you mean! We've already gone through that, what kind of outsider are you? My father and my six older brothers all know, yet they still laugh at me for siding with outsiders. It makes me so angry!"

"Hehe, calm down first, have some fruit to cool down."

Senior Sister Chen shook her head, her gaze fixed intently on Lin He. "I don't eat fruit, I want to eat..."

……

……

More than a month later, Lin He successfully bred two more level-four spirit beasts. He then took on a mission to guard the market in Huangfeng Valley and left the sect.
