A mortal cultivating immortality can nurture spirit beasts.

Time flies like water, and more than a year has passed in the blink of an eye.

Lin He stepped out of his cave and looked at the completely different scene outside, and couldn't help but smile.

Biling Island has changed dramatically and is no longer the desolate place it was a year or so ago.

Nangong Wan and Xin Ruyin had been here before, but firstly, their time here was short, and secondly, they lacked manpower. Nangong Wan was not good at these mundane matters, so the development of Biling Island was far from sufficient.

But now, under Lin He's guidance, all the basic facilities on Biling Island have been built.

Not only did he open up cave dwellings for everyone, but he also created the prototype of a sect, which Lin He named Tianyi Pavilion. He also built buildings such as the Refining Hall, the Treasure Pavilion, the Spirit Beast House, the Scripture Pavilion, the Talisman Hall, the Array Hall, and the Martial Arts Hall.

Lin He killed so many Foundation Establishment cultivators and more than a dozen Core Formation cultivators. His collection alone is equivalent to that of a small to medium-sized sect.

He no longer valued these things much, and since Biling Island had no shortage of spirit stones, he took them out to replenish his treasury.

His current identity is the Pavilion Master of Tianyi Pavilion. Nangong Wan, as the Deputy Pavilion Master, doesn't manage much affairs, so he has the final say on everything in Tianyi Pavilion.

Seeing this, Nangong Wan and the others also took out their collections. Of course, all of their collections combined were not as rich as Lin He's. But in this way, Tianyi Pavilion's foundation from the very beginning far surpassed that of ordinary sects, because it was not short of spirit stones at all. As long as it spent some time, everything that could be bought with spirit stones could be used to fill its treasury.

At this moment, various puppets can be seen everywhere on the entire Biling Island. Most of them are controlled by Lin He. The Qi Refining puppets are responsible for mining, transportation, and errands, while the Foundation Establishment puppets are deployed around the island to guard it.

Although there were only a few people on the entire Biling Island, Lin He couldn't help but nod in satisfaction at the unusually busy scene before him.

At this moment, a pretty figure walked over; it was Senior Sister Chen. She approached with a smile.

"Junior brother!"

Lin He couldn't help but remind him, "You should use your job title when you're working!"

Senior Sister Chen smiled and said, "Understood, Sect Leader!"

Lin He nodded. A year ago, when everyone proposed to establish a sect, Lin He made the decision on his own and named it Tianyi Pavilion. The name was indeed very imposing, and no one objected.

Lin He glanced at Senior Sister Chen and congratulated her, "Senior Sister, congratulations on advancing to the mid-Foundation Establishment stage."

"Honestly, I fought several Foundation Establishment demonic beasts to advance to the mid-stage, just to give you a surprise. I didn't expect you to see through it at a glance."

Lin He smiled, put his arm around her slender waist, and asked, "How is everyone's cultivation of the Great Evolution Technique going?"

Senior Sister Chen replied obediently, "Senior Sister Ruyan has exceptional talent. She was the first to complete the first level. Junior Sister Ruyin established her foundation later, so it will take her some time to complete the first level. Xiaomei has not yet established her foundation and cannot use the Divided Spirit Technique, nor can she control the puppet. As for me, I have now completed the first level."

More than a year ago, Lin He began to cultivate level seven egret fish demons. He borrowed eighteen pill corpses from Nangong Wan, refined them again, and was able to control them. He easily killed them and successively obtained more than a dozen level seven egret fish demon demon cores.

Using the seventh-level demon core and many materials purchased from the Miaoyin Sect, Lin He successively refined seventy or eighty Yin Spirit Pills.

This Yinling Pill is taken once every five years, three pills each time. It is equivalent to a Nascent Soul cultivator suppressing it with magic power. In this way, Xin Ruyin no longer had any worries. After Nangong Wan refined a batch of Foundation Establishment Pills, she finally succeeded in establishing her foundation by spending three Foundation Establishment Pills.

Speaking of Xin Ruyin, the latter had just emerged from seclusion.

"Sect Master!"

Xin Ruyin walked to Lin He's side, took a piece of his clothes, and said, "Ruyin has lived up to your expectations and has developed three formations that can resist Core Formation stage cultivators."

The array formations currently set up on Biling Island are very rudimentary. Apart from the improved version of the Inverted Five Elements Array that can temporarily withstand Core Formation stage cultivators, the other array formations can only withstand Foundation Establishment stage cultivators and their defensive capabilities are not very good. Lin He has always been dissatisfied with this. After Xin Ruyin found out, she studied it day and night, working overtime, and finally made some progress.

Lin He took the jade slip she handed him, and sure enough, it contained three different formations.

Of course, it was impossible for Xin Ruyin to have researched three formations in just one year. In the past few years, she would bury herself in research whenever she had free time. However, due to her limited Qi cultivation, her understanding of formations was always a little lacking. But since she reached the Foundation Establishment stage, her research efficiency has increased significantly, which is why she has achieved the results she has today.

However, setting up these three formations is not easy and requires purchasing a lot of valuable materials. Naturally, Lin He was given the task of purchasing these materials, as their cultivation levels were too low to go out at the moment.

Lin He kept this in mind, patted Xin Ruyin's head, and said, "Ruyin, thank you for your hard work!"

Xin Ruyin shook her head and said, "Young Master used countless rare materials to refine the Yin Spirit Pill for me. It is only right that I do these things. I only regret that my cultivation is too low to be of any help."

"How could that be? If you all complete the second level of the Great Evolution Technique, you will be able to control hundreds of puppets. At that time, you can replace me, and I can go into seclusion to cultivate in peace."

"Young master, Ruyin will try her best."

Lin He held them in his arms, one on each side, with unusual intimacy. Just then, Yan Ruyan, dressed in white, happened to pass by. Seeing this, Yan Ruyan said somewhat awkwardly,

"I'm sorry, Master, it seems I've arrived at an inopportune time."

"No, you've come at the perfect time!"

Lin He beckoned, and Yan Ruyan walked over. He said, "I was just discussing the Great Evolution Technique with them."

"I understand. I will master the second level as soon as possible, then the Sect Master can focus all his attention on preparing for Core Formation."

Lin He nodded. Among these people, Yan Ruyan was the most intelligent, Xin Ruyin was the most considerate, and Senior Sister Chen was the most innocent.

"Ruyan, it looks like you'll be advancing to the mid-Foundation Establishment stage soon too."

Yan Ruyan smiled and said, "Thanks to my senior brother for bringing me to this Biling Island, my cultivation speed is advancing by leaps and bounds. In a few more years, I will be able to advance to the late stage of Foundation Establishment. After taking the Spirit Ascension Pill, I will be able to advance to the late stage of Foundation Establishment."

Upon hearing this, both Senior Sister Chen and Xin Ruyin felt a pang of envy. With their Heavenly Spiritual Root aptitude and the Spirit-Ascending Pill, their cultivation speed was far beyond what they could achieve.

After chatting for a while, everyone went back to their own work. Tianyi Pavilion had just been established and was short-staffed, so everyone was very busy.

Eight years later, Yan Ruyan, Senior Sister Chen, and Xin Ruyin successively completed the second level of the Great Evolution Technique. Lin He also stopped controlling the puppets, handed over all these matters to them, and began to cultivate in seclusion.

Time flies like water, and thirty years have passed in the blink of an eye. On a deserted island tens of thousands of miles away from Biling Island, the once clear sky suddenly turned into a dark cloud cover, and the sky and earth changed color.
