Beizhou,

in the third month of the underground cave in the far north, the area covered by the formation was already full of flowers. The colorful flowers competed with each other, adding a touch of color to the cave.

A year later, 30% of the spiritual medicines Lin Jiang brought in survived. Lin Jiang's retreat was still intermittent, three to five days, or half a month. After waking up, Lin Jiang would take care of the flowers and spiritual medicines.

Then he drew talismans and read books. Lin Jiang brought a whole storage bag of books on alchemy, talismans, and formations, enough for him to read for a long time.

In the fifth year, Lin Jiang could refine the second-level formation by himself. He found several spiritual veins in the underground cave and attracted spiritual energy. The concentration of spiritual energy in the formation was raised to another level, and daily practice could be guaranteed.

In the tenth year, Lin Jiang raised his talisman drawing level to the extreme of the third-level upper grade. The talismans he drew filled the corners, and the third-level materials he brought were also used up.

In the twentieth year, Lin Jiang finished reading all the alchemy notes he brought, but Lin Jiang did not bring the alchemy furnace or materials, so he could not be sure of his level. In

the 30th year, Lin Jiang finished reading all the refining notes, and took out some low-level refining materials from the storage bag, and refined some daily necessities. Lin Jiang was reluctant to give up those rare refining materials.

In the 50th year, Lin Jiang's cultivation finally reached the perfection of the Golden Core. When he left Xuanmiao City, Lin Jiang had no human pills on him, so he could only practice hard. After

the perfection of the Golden Core, Lin Jiang did not rush to break through the Nascent Soul. He knew his qualifications too well. With only one Purple Heart Pill, Lin Jiang would never waste it.

In the 80th year, Lin Jiang had read all the information he brought for the third time, and he had already memorized it by heart. Lin Jiang began to practice various secret techniques.

In the 150th year, Lin Jiang tried to break through the Nascent Soul for the first time, and forced the breakthrough without elixirs. In theory, immortal cultivators do not need elixirs to break through any major realm.

But theory is theory, and reality is reality. Without the elixir, the success rate is around 1%, and the probability of breakthrough is very small. The environment of the immortal cultivation world does not allow you to achieve success so naturally. For example, the expectations of the elders of the sect, the competition for resources and status, the oppression of competitors and even enemies, all force the immortal cultivators to break through as quickly as possible, and the higher the probability of breakthrough, the better.

This is why there are breakthrough elixirs such as the Foundation Building Pill, the Five Elements Golden Fruit Pill, and the Infant Pill. Because of the huge demand, the price is extremely expensive, far exceeding the value of the elixir itself.

In today's immortal cultivation world, except for the poor casual cultivators, no one will break through without elixirs. The conditions do not allow it.

Lin Jiang failed in his first breakthrough as a matter of course. Fortunately, without the powerful impact of the elixir, the damage to the body was minimal, and he recovered after three months of recuperation.

As early as the 80th year after he came in, Xiao Sha Diao had woken up. Most of his injuries were healed, but there was something wrong with his wings. His wings were crushed by Zhou Huaiying, and Lin Jiang had to perform an operation on him.

Without anesthesia, his wings were cut open, the bones inside were broken again, and then pieced together bit by bit, which made the little sand sculpture curse in pain. After

recuperation for many years, the little sand sculpture finally recovered completely. Lin Jiang did not bring many beast spirit pills, and they were gone after eating them. Lin Jiang asked the little sand sculpture to practice on his own.

The demon race itself also has its inheritance. They are inherited by blood and are born with it. They devour the spiritual energy of heaven and earth and can also advance slowly.

The little sand sculpture is like other demons. Most of the practice of the little sand sculpture is based on sleeping. Once asleep, the demon body will actively absorb the spiritual energy around it and increase its cultivation, but it is extremely slow. The little sand sculpture does not like this method of practice.

Because he is also a bird that is used to wandering. The outside world is so fun, there are a lot of delicious food, and there are beautiful fairies to talk to, but here, Lin Jiang does not allow him to go out, so he can only sleep and practice.

In the 200th year, Lin Jiang failed again in his second attempt to break through without elixirs. Lin Jiang began to concentrate on practicing secret arts, which took a hundred years. During this hundred years, Lin Jiang practiced many secret arts such as the Lighting Technique and the Hidden God Technique to the extreme.

In the 350th year, Xiao Sha Diao finally broke through the middle stage of the fourth order, but Xiao Sha Diao also admitted that if there were no treasures or opportunities, he basically had no hope of breaking through the fifth order, and might break through the late fourth order in his later years.

The lifespan of the demon race is not fixed, and different demon races have different lifespans. The lifespan of the Aurora Falcon is only medium among the demon races. The middle stage of the fourth order can live about 2,000 to 3,000 years. Xiao Sha Diao is several dozen years younger than Lin Jiang and can live for a long time.

In the 360th year, Lin Jiang broke through the Nascent Soul for the third time without spiritual medicine. This time was the closest to success. He had already broken the pill and condensed the Nascent Soul. He just stopped at the last step, which greatly boosted Lin Jiang's confidence.

"Even if I used the top-level jade box, the efficacy of the Purple Heart Pill has lost 20% in nearly 400 years. I can't wait any longer. I must break through within 20 years."

Lin Jiang opened the Purple Heart Pill and took a look. The Purple Heart Pill had been successfully refined for hundreds of years. Lin Jiang used the top-level jade box to preserve it, but it was still slowly losing its efficacy.

"Dad, when did we get out? We have been here for tens of thousands of years, right?"

"What the hell, you can still live for tens of thousands of years, do you think you are me?"

Lin Jiang said. He had a system that could record the years. He had only been here for 380 years. The little idiot was really stupid.

But it was not his fault. The range of activities was only the size of the ten acres of this formation. He had already counted the stones on the ground. It was really boring. There was no sun or moon in the mountains. It was normal to forget the passage of time.

"Dad, I miss my wife."

"Don't act innocent in front of me. You have a wife, but you still go to the Zongmiao Tower."

"Dad, my wife won't run away with someone, will she?"

"Think positively. What if she's dead?"

"..."

"Go and practice, and try to live for 10,000 years."

Lin Jiang waved his hand, and the little sand sculpture got out of the way. It found that it couldn't compare to someone even if it was cheap, so it's better not to make trouble for itself.

In the 420th year, Lin Jiang finally decided to use the Purple Heart Pill. His cultivation had already been perfect. He had broken through three times without the pill, and this time he would definitely succeed.

"Take these spirit stones. Once the spirit stones of the spirit gathering array are used up, you will make up for it for me. Don't let the spirit power of the spirit gathering array run out, understand?"

Lin Jiang woke up the little sand sculpture and asked it to protect the law. He took out all the accumulated spirit stones. The spirit gathering array brought by Lin Jiang was not big, and could only hold a few thousand spirit stones at a time. This amount of spiritual energy was not enough, so the little sand sculpture needed to make up for it temporarily.

"Dad, do you have enough spiritual stones?"

"Enough, the spirit formation has been adjusted. Except for the necessary formation and spiritual medicine, all other parts are closed to fully support my breakthrough."

Lin Jiang nodded. He now had only medium and high-grade spiritual stones in his hands. The others were used up, but he had accumulated the spiritual energy of the spiritual vein for many years, and the spiritual energy was almost turning into mist. After

giving instructions, Lin Jiang directly closed the formation, placed the purple heart pill and auxiliary pills in front of him one by one, and started to break through again.

After many breakthroughs, Lin Jiang was already familiar with it. He broke the golden pill that was finally condensed again, and then filled the dantian with spiritual power.

Using the divine consciousness to condense the spiritual power and outline the prototype of the Nascent Soul, this step took Lin Jiang three years. After the Nascent Soul was formed, things were not over yet. The most important next step was to attach the spirit.

Using the spiritual consciousness as the trigger and the spirit as the foundation, the Nascent Soul is born into a new spirit. This is a brand new Nascent Soul. Theoretically, after the Nascent Soul, even if the physical body is broken, the Nascent Soul can survive independently without being hurt, because the Nascent Soul is semi-independent from the body.

This process is long and complicated, and requires persistent efforts. It is not enough to rely solely on spiritual power to restore the consumed spirit, so the Purple Heart Pill comes in handy. The auxiliary pills taken with the Purple Heart Pill can protect the meridians in Lin Jiang's body from being damaged by the powerful drug power.

In the 440th year, with a burst of powerful pressure, the Nascent Soul in Lin Jiang's body opened his eyes, bright and energetic, successfully attached to the spirit, and successfully broke through.

"After nearly 900 years of hard practice, the Nascent Soul is finally here."

Lin Jiang let out a long roar, relieved the depression in his heart, and felt quite comfortable. At this time, he had been in the cave for 440 years. In another two years, he would be 900 years old. If it were someone else, they would almost die in the Nascent Soul stage.

At this time, the Nascent Soul was still extremely fragile, and Lin Jiang had no intention of coming out of retreat. He continued to retreat and consolidate his cultivation realm.

The little sand sculpture was counting the remaining spirit stones outside the formation in boredom. It already felt that the bird's life was boring. If it didn't go out for a walk, the bird would be depressed.
