When Mr. Fei heard this, he smiled and said, "If you don't like my elixir, you can pick the spiritual medicine on my medicine peak if you need it. I won't say anything, how about it? I'm generous enough, right?"

Hearing this, Tang Ning's heart moved, glanced at him, and smiled and said, "Document!"

Follow her to his alchemy room, and as soon as he entered, he saw a huge alchemy furnace, and a medicine boy was helping him look at the fire, looking at his alchemy furnace with various runes engraved on it, Tang Ning was slightly surprised.

"So big? And you are practicing the elixir in this furnace, and you can still run out? Just let a little medicine boy watch you? Is this too big a heart?"

When he heard this, Old Fei looked at him in surprise: "Did you have no medicine for your elixir to help you see the fire?"

Tang Ning shook her head: "No, I'm all done by myself." She was used to controlling it herself, and she used the natal heavenly fire to refine the alchemy, but what he saw here was the fire from the center of the earth. The two were also different.

"Master." When Yao Tong saw him coming in, he quickly bowed.

"Okay, you go out!"

Mr. Fei waved his hand and asked the medicine boy to go out first. He went up to look at the fire, then looked at Tang Ning and said, "I have tried this elixir several times, but it will fail when adding Xingtiancao. What is the reason?"

Tang Ning stepped forward and smelled the fragrance of medicine emitted from the furnace, glanced at him, and said, "Did you refine the foundation-building pill?"

"Hehe, it smells it? Not bad, it's the Foundation Building Pill." He only put less than half of the spiritual medicine he wanted to put in this furnace of elixir, and he could also smell it was the medicine for the Foundation Building Pill, which shows that he was asking the right person.

"I have also refined the foundation-building pill, mainly using medicine and heat control. For example, this Tianxing Grass cannot be put too early or slow down. I will help you refine this furnace of pills here. You can watch it and understand how much." Tang Ning said, walking to the medicine table placed aside and looking at the spiritual medicine he prepared.

"Okay, you practice! I'll watch from the side."

He said, coughing lightly, as if he was afraid that he would not even be able to refine the foundation-building pill, and explained: "Actually, I have successfully refined it, but at most one furnace in ten furnaces can be successful. The success rate is too low, and there is only one finished pill in one furnace, so I want to exchange experience with you."

"Yeah." Tang Ning responded, opened the cover of the stove, picked up one of the spiritual medicines, and threw it into the stove. He picked up another spiritual medicine to take its rhizomes as medicine.

Fei, who was watching from the side, picked his leaves when he saw him a hundred-year-old spiritual medicine, and he didn't want anything else. The other plant only took the rhizome and threw it into the furnace at will, and he didn't worry about adding more or less, so he stared at him.

Can this foundation-building pill be refined like this?

He couldn't help asking, "Why did you take only the leaves of that elixir? I usually use the whole plant, and there are the rhizomes of the other plant, don't you want the ones on it? You put it in casually, and didn't ask me about the proportion of the ingredients of the other medicines in the furnace. In this way, will the elixir of this furnace be ruined?"
