Reborn as a girl, I will live forever in the world of immortality

Fortunately, He Ling has no shortage of spiritual medicines, so the routine matters of refining pills are handed over to Tu Lu. After piling up numerous spiritual medicines, Tu Lu is now considered a master of alchemy and He Ling's chief alchemist.

He Ling mentioned this specifically because she knew she was playful.

Tu Lu opened her mouth and was obviously reluctant, but she also knew the importance of the matter, so she agreed obediently.

He replied, "Oh."

After explaining the situation to the two, He Ling glanced at Xiao Hong, then said to the Tu Lu siblings, "Alright, these days are special, so you should be more careful. Go back."

After the two left, He Ling took Xiaohong to a room.

Compared with before, this place is much more luxurious. It has everything, including tables, chairs, benches, bookcases, and soft beds. Even the floor is covered with a thick gold-thread carpet.

With a spell, the carpet opened by itself, revealing a secret door underneath.

After walking down the secret door, there was a bright red spiritual field inside. The top was inlaid with gems of various colors, and there were several translucent formations guarding this place. It was the underground spiritual field that He Ling carefully made and purchased to be guarded by the formation.

He Ling had hardened the surrounding walls with magic, so it looked like they were made of stone.

When he arrived at the spiritual field, He Ling waved his hand, and a piece of soil in a corner of the spiritual field was lifted up. Then he cast a spell, and the ground there quickly hardened and turned into a red stone surface.

Coming to the stone surface, He Ling took out a cushion and a small stove, and then looked at Xiaohong.

"Xiaohong, I'll be in seclusion for a while. If anyone else comes to visit, you can ask Tuba and Tulu to refuse. If they really can't refuse, wait until someone breaks in. Then you can notify me. You're the only one who knows this place, so you don't need to tell Tuba and Tulu."

"Ying ying."

He Ling laughed, pulled Xiaohong over, and touched its head twice.

"Don't worry, it's not a big deal, just a little trouble. I'll take care of it when I return from my retreat."

After Xiaohong left, He Ling looked at her sleeves. You could say she was cautious or suspicious, but she liked to make preparations before doing anything.

"Qing'er, you just stand guard at the door for the time being. If anyone or anything other than Xiaohong comes in, just swallow it whole."

Qing'er nodded and turned into a green light, floating towards the entrance of the secret door. Then her body shrank and she turned into a tiny worm less than half an inch long. She hid in the cave entrance and disappeared.

After explaining everything, He Ling raised her hand and three storage bags flew into her palm. These were the storage bags full of elixirs that Qing'er had swallowed before.

There are no caves in Tianning Market, and there are many foundation-building cultivators there. It is naturally impossible for He Ling to refine the elixir in the room. After much thought, he decided that the spiritual field he created was in the best location. It was guarded by multiple formations, and no spiritual energy would leak out. There was also a formation to maintain it, and the concentration of spiritual energy in the air was much higher than outside.

More importantly, this place is hidden enough that even the Tulu Tuba siblings who live with He Ling day and night don’t know about the existence of this place.

As soon as the thought flashed through his mind, his spiritual thoughts penetrated into the storage bag, and spiritual medicines floated out of it one after another.

He Ling's mind moved and he cast a spell. The soil underground seemed to come alive, squirming and piling up the soil. In a moment, rows of shelves appeared out of thin air on the ground. Then a ray of light floated towards these shelves. The next moment, the shelves hardened in an instant and turned into rows of stone shelves.

Afterwards, He Ling took out these elixirs one by one and arranged them in order.

He Ling's spirit was powerful, and he could do things quickly and effectively. In a short while, all the spiritual medicines were arranged in order.

She opened the lids of the mature spiritual herbs and placed them on the shelf, while she closed the lids of the unripe spiritual herbs and placed them in storage bags.

Now she has enough spiritual medicines to refine the foundation-building pill, so there is no need to ripen them now. However, these seedlings are not useless. If she can't use them, she can give them to Tulutuba and others. He Ling plans to expand her power in the future. After she is promoted to the foundation-building stage, she will not have to be restricted like before. At that time, these seedlings will be of great use.

After counting the number of these mature spiritual medicines, He Ling was certain that these spiritual medicines were enough for her to refine about four or five furnaces of spiritual medicines. Even if she used the lowest success rate, with two foundation-building pills in one furnace, she would have at least eight foundation-building pills.

With these eight foundation-building pills, no matter how poor her aptitude is, no matter how much spiritual power the seven-colored lotus requires, she can build up her foundation by simply piling up the foundation-building pills!

However, after having an idea in mind, He Ling did not start refining the pill immediately. She first sat on the cushion and meditated, circulating the Qi several times until her mind was completely calm. Only then did she open her eyes.

She raised her hand and a thin piece of yellow paper appeared in her hand. On it were written a few large characters, which were - the recipe for the foundation-building pill.

Although she had read the recipe for the Foundation Establishment Pill countless times, she was still afraid that there might be some mistakes, so she had to read it again before refining the pill.

After reading it once, she sent a stream of spiritual power towards the small furnace. The small furnace turned around and flew in front of He Ling. Then He Ling stretched out her left hand and a ball of flame came out. When the furnace burned to golden color, she waved her hand and a spiritual medicine flew over and was thrown into the furnace.

As soon as the elixir entered the cauldron, the green stems and leaves of the elixir tumbled a few times in the furnace and turned into a white liquid. The white liquid looked like a pool of water at first, but after a blink of an eye, it boiled in an instant.

He Ling's expression remained unchanged. He waited for the white liquid to boil for a while before adding the next elixir. Then he saw the white liquid growing bigger and bigger until it turned into light yellow.

After burning for a long time, I saw that the light yellow color did not change at all.

He Ling frowned, and the spiritual fire in his hand also grew stronger, but this time no matter how He Ling urged the fire, the light yellow liquid did not change at all.

"What's going on? Is the recipe fake?"

He Ling's face looked a little ugly, and a surge of anger rushed to her head.

According to the recipe, the color of the medicinal liquid should become darker and darker in the fire. However, He Ling burned it for a long time, but the color did not change at all.
