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

The next moment, He Ling felt heavy-hearted. If every time he was promoted, there would be no hiding or retreating like this time, wouldn't there be great danger in the future?

However, He Ling only thought about it for a few seconds and threw the idea away. She hadn't even established her foundation yet, but she was already thinking about the future after the Golden Core and Nascent Soul stages. She didn't know how many years would pass before she really reached the Golden Core stage. Besides, no matter how impatient she was, it would be of no use dealing with the future now.

Once this thought came to mind, He Ling's thoughts became clear again.

This treasure spring is related to her life and property, and she will never give it up. Besides, cultivating immortals is against the will of heaven, and there are countless hardships. Without the treasure spring, she might just be a mortal and starve to death early in the mountains behind the village.

With determination in his mind, He Ling exited the Baoquan space the next moment and began to concentrate on recovering his spiritual power.

So on the next day, He Ling repeated the previous steps and let the Fire-Swallowing Pearl absorb the firepower of the Yangyan Sword.

Just like this, half a month passed in the blink of an eye.

On a cushion, a girl-like woman in a white robe exhaled a breath of foul air.

She looked at the small orange-yellow bead in her hand that was already glowing slightly, and a smile appeared on her face.

This Fire-Swallowing Pearl can absorb the power of the fire veins in the Earth Lung for decades and store it inside. Although the flame of the Yangyan Sword is powerful, it cannot fill up the Fire-Swallowing Pearl in such a short time. However, for He Ling, as long as this flame is enough to refine the pill, it will be fine. For this reason, He Ling added several times more flames. Now, there is enough in this Fire-Swallowing Pearl for He Ling to refine more than a hundred pills.

Seeing that everything was ready, He Ling finally started refining the elixir again.

She closed her eyes and first recalled the foundation-building pill formula in her mind. Then she opened her eyes and raised her hand. The three-foot-high and two-foot-wide bronze pill furnace spun and floated into the air, reaching the same height as He Ling's chest.

He Ling cast a spell at the Fire-Swallowing Pearl in his hand. The Fire-Swallowing Pearl flashed with yellow light and came to the bottom of the alchemy furnace. Then a red flame emerged from the Fire-Swallowing Pearl. This foundation-building fire was indeed much stronger than He Ling's spiritual fire. As soon as the flame emerged, the bottom of the alchemy furnace was burned red.

He Ling frowned and cast another spell, and the flames emitted by the Fire-Swallowing Pearl became less.

Although this Fire-Swallowing Bead is easier to control than the Yangyan Sword, it is essentially also a killing magic weapon. He Ling still needs to constantly adjust it during the alchemy process.

Soon, a burst of white smoke came out of the furnace, and after waiting for a while, the furnace was heated up.

He Ling controlled the Fire-Swallowing Pearl with one hand, and raised the other hand, and several spiritual medicines floated to He Ling's hand.

With a move of her white hands, a spiritual medicine was put into the furnace. After a while, it turned into a pool of boiling white liquid. He Ling's face was serious at this moment, and she put in other spiritual medicines in an orderly manner.

Ten more elixirs were added, and the medicinal liquid in the furnace turned light yellow again.

He Ling looked nervous, knowing that the next moment was the moment to verify whether his guess was correct.

She didn't dare to be careless at all. She carefully controlled the Fire-Swallowing Bead with her left hand, increasing the fire power little by little.

Finally, the color in the furnace changed. The light yellow spiritual liquid boiled for a while, then calmed down. Then the color of the liquid became darker and darker, from light yellow to dark yellow.

A gleam of light flashed in He Ling's eyes, and he knew it was now!

She waved her right hand and threw dozens of spiritual herbs into the furnace. The color of the medicinal liquid became a little lighter.

Then He Ling repeated the steps several times. Whenever the medicinal liquid turned dark yellow, He Ling threw in a batch of spiritual medicine. He repeated this three times until the last three main medicines were also put into the furnace. He Ling then waved to call for the lid of the furnace and closed it.

Then He Ling focused all his attention on controlling the firepower of the Fire-Swallowing Pearl.

The temperature for refining the foundation-building pill is extremely critical, requiring three slow and three fast steps. If any one of the steps is not done well, it may ultimately affect the quality of the final pill.

He Ling knew that it was now the last two stages and he did not dare to be careless at this moment.

First, use a steady low fire. After burning for a while, immediately start a high fire. Burn it for a while and then switch back to a low fire. Repeat this about 10 to 20 times.

He Ling was not happy until he smelled the fragrance of medicine wafting from the furnace. However, he knew that this was not the time to open the furnace. He still needed to bake the pill on a small fire to make the pill into pills. Only then could it be considered successful.

But the next step is much simpler. You just need to control the fire-swallowing bead to keep it burning at a low flame.

This last step was quite time-consuming. He Ling baked it over a low fire for five days before a burnt aroma came from the furnace.

When He Ling smelled the burnt aroma, there was no smile on his face, but a hint of nervousness and uneasiness.

After waiting for a long time, until most of the fire in the furnace had dissipated, He Ling opened the lid.

As soon as the bronze dome furnace lid was opened, a white mist came out, and two dark brown pills were seen lying in the furnace, but around these pills, there were also a lot of black pill residue floating.

He Ling knew that it was because she had made a mistake before and had wasted the pills, but she was very happy that she was able to produce two foundation-building pills.

She didn't even use any object control skills, she just reached out and picked up the two pills.

The two pills were dark brown in color and round in shape. They emitted a medicinal fragrance. Just by smelling it, He Ling felt a coolness in her head and saliva welled up in her mouth, which made her swallow a lot of saliva.

He Ling resisted the urge to swallow the pill immediately and said with some regret, "It's a pity that I didn't control the temperature well, causing the fire to burn a little too strong. Otherwise, the quality of this foundation-building pill would be much better."
