At this time, the old man interrupted his thoughts by speaking.

"Master, I would like to ask you why the substance made from lead and mercury has the effect of heaven and earth spiritual beings?"

Huang Laodao's main practice is to eat mica and Ganoderma lucidum, which is a school imitating the practice of Qi practitioners in the pre-Qin Dynasty.

Due to lack of resources, they developed a method of taking mica, crystal, and Ganoderma together.

But these are just one-plus-one methods.

When they followed the scent of medicine and came here, they accidentally saw Song Lin using gold, stone, animals and plants to make elixirs, and exerted one plus one to be greater than two medicinal properties, and they were immediately shocked.

From then on, they came here every day to ask for advice, but unfortunately they never saw him.

"So you want to know this...it doesn't hurt to tell you." Song Lin was in a good mood today.

Moreover, these people are not bad in intelligence. Telling these people the method of alchemy may help you in the future.

Xuan Ke Guan is not a sect that specializes in alchemy, and Huang Bai Shu is not advanced, it is just basic at best.

"Thank you, Immortal!"

These Huang Lao Taoists, like students, pricked up their ears and held their breaths for fear of missing something.

Some even tore off their fine clothes in an attempt to record Song Lin's words and deeds.

"This is Huangbaizhu, which is a method of extracting medicinal properties from gold, stone, and spiritual plants using fire. Gold, silver, lead, mercury, realgar, and cinnabar contain the essence of yin, yang, and five elements of heaven and earth, but it is toxic in itself. The dross must be removed by using fire.

Essence.”

"That's it!" Everyone suddenly realized.

The veteran leader couldn't help but sigh.

It is truly a miraculous feat that towers over heaven and earth.

This technique does not rely on nature, but uses your own hands to turn decay into magic and create treasures from heaven and earth.

Thinking of this, he asked: "Immortal, may I ask how to use fire to remove the residue? What's the trick?"

"It's very simple..."

Wow!

At this time, Song Lin's eyebrows flashed with white light.

Guanyue Cha appeared at his feet.

It turns out that the great witch left a secret to activate it.

Guanyuecha disappeared into the horizon with Song Lin.

"Immortal! Immortal!"

Everyone looked annoyed. It was obvious that the opportunity was right in front of them, but in the end they were still one step away.

"Perhaps the immortal is testing us on purpose."

"Yes, spells cannot be passed lightly. These are enough. Let's go back and study them first."

Huang Laodao and everyone dispersed.

After that, they will record in the classics what happened today when they met the immortal and received the elixir.

They called Song Lin who disappeared in the moonlight the Taixu Immortal.
