Lin Feng took the paper and pen, and wrote down the pill formula for the Pei-Yuan Dan:

"This is the pill formula, hurry up and gather all the required ingredients. Once all the ingredients have been gathered, get Luo Zicheng to send them over to me."

When the Luo Family members received the pill formula, they couldn't help but gasp.

"A hundred years old ginseng, a thousand years old chief Wu …"

The ingredients required for the recipe were mostly the rarer and rarer herbs. A few of them were even rarer. Even with the strength of the Luo Family, they would probably need a lot of time to find these herbs.

"Master Lin, it's very difficult to collect most of the herbs here, and there are a few that are even more difficult. It's almost impossible to collect all of them in a short period of time …"

They didn't know how long it would take to collect all the ingredients, or if they delayed it too long, it might affect the old man's body.

Although the old man had already recovered quite a bit, no one could guarantee whether he would relapse and have enough time to wait for the pill to be successfully refined.

Lin Feng knew the rarity of these medicinal ingredients on the pill formulas, and naturally saw the worry in the Luo Family clansmen's hearts.

"That's good, that's good!"

After the worries in their hearts were dispelled, the people of the Luo Family let out a sigh of relief, and immediately gave out orders. Even though they already knew from Lin Feng that it would take much more time to gather the herbs before the Yin energy disappeared, they still wanted to complete the collection as fast as possible.

One day, he would complete the herb collection, another day, he would complete the pill concocting, and another day, he would recover completely. Only then would he be able to completely breathe out in relief.

The gazes of the Luo Family clansmen continued to fall on Lin Feng's body as they asked respectfully.

Lin Feng waved his hand casually, "It's alright, in this world, other than me, even if others have the pill formulas, they would be of no use."

"Pill Refining. Although pill formulas are important, they are more important than pill formulas. All of these pill formulas require the cooperation of my exclusive method. Otherwise, even if I had the pill formulas, I would not be able to successfully refine them." Lin Feng continued.

"So that's how it is."

"Master is indeed worthy of being called a master!"

"A unique forging technique..."

"Presumably, even among alchemists, the Master Lin is one of the best."

Before his rebirth, Lin Feng was the one and only strongest Medical Saint in the Ninth Heaven.

Lin Feng knew that his grandfather's illness was actually not that serious. The most important reason why he was in such a state and had fainted today was because of the corrosion of the Yin energy.

To avoid corrosion, there were only two options. To avoid it, one had to consume the Essence Nurturing Pill, and at the peak of his inner strength, he could ignore that kind of corrosion, or break through the Yin Energy.

"Furthermore, not to mention the Luo Lao, everyone who continues to stay here before the Yin energy is broken, will slowly be affected by it. Even if this is a land filled with wind and water, spiritual energy can cancel out the Yin energy, so it's impossible for them to stay here for a long time."

"Once the Yin energy has invaded to a certain extent, it will cause the body to be affected. If it is serious, it could endanger one's life."

The villa was located in a land of good Feng Shui. In an environment like Earth, the spiritual qi in the villa was quite dense.

A calamity came and went, and he died a horrible death!

Or perhaps, it was a narrow escape from death.

"Baleful Yin Force? Master Lin, why would there be baleful qi here? "

As cultivators, they were well aware of the feng shui situation here. The best Feng Shui Treasures were places that produced spiritual energy. They definitely should not have Baleful Yin Force.

"I'm curious about this as well."

Lin Feng slowly squinted his eyes. There was a possibility that the insides of such a villa would continuously produce Baleful Yin Force.

"Let's go, take me to the bas.e.m.e.nt to take a look."

"Master Lin, this way, please." Luo Zicheng and his family greeted him respectfully.

Before he could open the door to the bas.e.m.e.nt, he felt a bone-piercing chill.

Upon entering, even under the illumination of the lamp, one could still feel a ghastly aura. This eerie aura also carried a hint of coldness, revealing an unspeakable eeriness everywhere.

Lin Feng concentrated on scanning around, and quickly found the source of the problem. In that moment, his entire body could not help but tremble:

"I didn't expect to see the blood burial technique of the Witch Clan on this earth."
