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

There was a curtain hanging at the door, so Qi Wan couldn't see what was going on inside.

He Ling responded and walked out quickly. When she pulled aside the curtain, she saw Qi Wan with an apologetic look on her face.

"Sister Ling'er, it's my fault that I'm not good at alchemy and I've wasted some of your best elixirs."

It turned out that Qi Wan had been preparing for several days and had even picked an auspicious day to start refining the elixir. However, she didn't expect that the elixir would be ruined after the first batch.

After listening to Qi Wan's explanation, He Ling didn't care much. She had no shortage of elixirs, and she gave Qi Wan the elixirs mostly for future considerations. Failure was understandable. Moreover, even some experienced alchemists would not dare to guarantee a 100% success rate in refining elixirs.

However, seeing Qi Wan's apologetic expression, He Ling still comforted her, "It's okay, Sister Qi Wan. It's common for alchemists to fail a few times. I still have a spiritual medicine for He Qi Dan here. Sister Qi Wan, you can try again."

As he spoke, he took out seven or eight wooden boxes from the storage bag and handed them to Qi Wan. Qi Wan wanted to refuse, but He Ling repeatedly assured her that it didn't matter even if she failed, so Qi Wan finally accepted the elixir.

After Qi Wan left, He Ling returned to the room, "Qing'er." After feeding a pill to Qing'er, He Ling sat cross-legged on the stone bed again, but instead of practicing, he started thinking.

The spiritual medicines needed for the Thunder Body Tempering Technique were not many. She already had four or five kinds. As for the few spiritual medicines that were missing, the others were okay and not precious. She estimated that she could collect them all by visiting the street of casual cultivators in a year. However, there was one kind that was a bit troublesome.

Bone-dissolving grass is a magical medicine that only grows on piles of bones, and it can only be born on the skeletons of a large number of monsters or monks with spiritual energy.

To find this elixir, besides going deep into the Yuxian Mountains, He Ling could think of another place: the lake where the Mysterious Ice Toads lived! The Mysterious Ice Toads would certainly not let go of the onlookers that day, and with only two of them at most, they definitely couldn't devour so many cultivators. There must be a large number of cultivator bones piled up around the lake, making the chance of Bone-Dissolving Grass appearing there extremely high. However, the danger was equally significant, so He Ling could only imagine it; he definitely wouldn't go.

As for the depths of the Yuxian Mountains, He Ling was a little hesitant. She was now endowed with multiple spiritual weapons. Although she could not win, if she wanted to escape, as long as she did not encounter speed-type monsters, she would probably have no problem.

However, after careful consideration for a while, He Ling decided to stay in the cave. She had endless time. Even if the success rate was 90%, there was still a 10% chance of death, a full 10%. What was the difference between that and committing suicide?

From then on, He Ling lived a life of going back and forth between two points, giving spiritual medicine drops from the treasure spring, practicing, feeding the two dogs, feeding Qing'er spiritual beast pills, and then practicing.

Qi Wan came to the door again a few days later, and this time she was successful, but the pill yield rate was disappointing. Only two pills were produced from a furnace, and the rest were wasted as usual.

However, He Ling still said she didn't care, and took out a few boxes of elixirs and gave them to Qi Wan, asking her to keep up the good work.

Qi Wan was very grateful to He Ling, who was trying every possible way to help her improve her alchemy skills, and she didn't ask for any reward. Qi Wan was so moved that she almost cried. At this time, He Ling also proposed to learn alchemy from Qi Wan. She had had this idea for a long time, but the Qi Dan in the storage bag gave her a glimmer of hope. However, after a few days, her cultivation level was still the same, which discouraged He Ling. It would be more realistic for her to learn alchemy from Qi Wan.

Qi Wan was naturally very willing to do so, and she even gave He Ling a brand new alchemy furnace. This surprised He Ling very much, as an alchemy furnace would cost at least one or two hundred spirit stones, but Qi Wan actually gave it to her directly. However, after thinking about what she had done these days, although it was just a matter of convenience for her, from Qi Wan's perspective, He Ling was like her half-sister, and even her biological sister would probably not be any more so.

He Ling pretended to be polite, but Qi Wan was still a little unhappy. In the end, she had no choice but to accept the furnace.

When He Ling first started learning alchemy, she had a lot of ideas in her mind. She always wanted to do something fancy and practice alchemy according to modern standards. However, when she really came into contact with it, she gave up this idea.

The pill formula and operation process are similar, but the real difficulty in alchemy is that the spiritual energy content of each spiritual medicine is different due to its age, and alchemy is extremely particular about details and temperature. Sometimes, with the same pill formula and the same spiritual medicine, the timing of adding the medicine will be different because the spiritual energy content of the spiritual medicine is a little less this time. This is almost impossible to quantify. Even experienced old alchemists have failed in this process many times, so alchemy depends entirely on the alchemist's experience and control of the temperature.

There is also the spiritual fire used for alchemy, which is also ignited by the cultivator himself with his spiritual power, and the temperature can be precisely controlled. Therefore, when refining the alchemy, one must consider the temperature as well as the timing of the spiritual medicine. The addition of all the big and small things in between leads to the low success rate of alchemy.

But sometimes He Ling thought, it would be great if she could find a way to uniformly control the age, spiritual energy content, and size of the spiritual medicine. She tried her own treasure spring as soon as possible, but in the end she found that even if she accurately controlled the age of the spiritual medicine to within one year, the maturity of the herbs would still be completely different.

He Ling experimented for a long time before discovering that the mere difference in ripening time had already resulted in completely different spiritual energy contents in the two spiritual herbs. If she wanted to precisely control it, she was afraid she would have to find a place devoid of spiritual energy. However, without spiritual energy, spiritual plants could not grow...

He Ling almost fell into a vicious circle. In the end, he thought about it until his head bald but still couldn't figure it out. In the end, he simply gave up and obediently followed Qi Wan to learn alchemy.

Following Qi Wan's suggestion, He Ling decided to start refining the Spirit Beast Pill. Firstly, she had almost all the spiritual medicinal seeds for the Spirit Beast Pill. Secondly, it was not complicated to refine and could also meet Qing'er's daily needs.

In a stone chamber, Qi Wan was explaining to He Ling the difficulties and precautions of refining spirit beast pills.

"After you see the spiritual medicine dissolve into spiritual liquid, turn slightly white, and form some bubbles, you can add the next spiritual medicine. Remember the order must not be wrong, and then just repeat. Sister Ling'er, these are the difficulties. The Spirit Beast Pill is just an initial pill recipe. Sister Ling'er, you are very smart, don't be discouraged, it's just a failure, one, two, three, four, five, six, seven times, right? This time there will be no problem."

He Ling's face turned slightly red when he heard this, but he immediately cleared his throat and nodded seriously. Then he used his spiritual power, and a furnace the size of a rice cooker floated in front of He Ling. He Ling chanted a spell and made hand gestures, and a wisp of orange-red flame rose from his fingertips.

"Hot stove, hot stove off, add the elixir, turn white! Right now."

"Sister Ling'er, the heat is on!"

As a burst of black smoke rose, a furnace of liquid medicine turned into waste liquid again.
