The daughter-in-law's son-in-law

"Okay, things are done well, let's take them in first."

Liu Feng nodded. There are many spare rooms in the villa, so there is no need to worry about no place to put things.

He found a remote utility room and put all these messy things in it.

Du Dachuan was very knowledgeable and took the initiative to say:
"I'll wait for you in the front house, if you need anything else, please let me know."

"Need not."

Liu Feng waved his hand and said lightly:

"It's just refining some simple medicines, and it's not really a secret. During this period of time, you've been doing things for me, so stay and have a look."

"Thank you Brother Liu Feng!"

Du Dachuan never expected that there would be such a good opportunity, and tears of excitement almost flowed down his cheeks. The art of alchemy has been lost for many years, and being able to see it with his own eyes is definitely a golden opportunity that can only be met but not sought after.

Liu Feng shook his head, frowned and said displeasedly:

"It doesn't need to be like this between you and me, don't do it in the future. Bring me the things."

It can be said that Du Dachuan spared no expense in buying things. This copper furnace is about half a person's height, and the whole body is bright golden yellow, which is obviously very valuable.

The other medicinal materials are also of the highest quality, almost the best that can be bought on the market.

But these are all artificially bred after all, and the color is very average, Liu Feng is not picky, after all, this time is just a test of the water.

After he put the copper furnace in place, he put the medicinal materials in order.

Time passed by every minute and every second, the flames in the small room were beating, and a vague fragrance gradually permeated.

Du Dachuan's expression revealed excitement, his eyes were wide open, for fear of missing any details.

About an hour later, Liu Feng's slightly closed eyes suddenly opened, he patted the copper stove in front of him lightly, and said lightly:

"The next step is the most critical step."

He didn't expect Du Dachuan to see any tricks, but he felt a little sorry for this hard-working person who almost lost his life because of him.

Du Dachuan nodded like a chicken pecking at rice.

Liu Feng took a deep breath, the light in his eyes soared, wisps of powerful true energy gushed out from his palm, there was a tinkling sound from the small copper furnace, and the lid trembled faintly, as if Something is about to jump out of it.

Oops, true Qi hasn't recovered yet!

Liu Feng's complexion changed slightly, the true energy needed for alchemy was somewhat beyond his imagination, and he couldn't control it for a while.

Usually when this happens, it is the so-called fryer, and the alchemy person will be seriously injured, and if it is serious, it will explode on the spot, leaving no bones left.

Fortunately, Liu Feng has lived for countless years, and the most important thing he lacks is experience. Although this situation is extremely endangered, his expression is still calm as usual. He slapped it up with a slap.

Ding!
With a crisp sound, the stove suddenly subsided, followed by a burnt smell.

Du Dachuan didn't dare to catch his breath while watching from the sidelines, swallowed his saliva, and asked nervously:
"Brother Liu Feng, is this a failure? How about I prepare another raw material?"

"Need not."

Liu Feng opened the stove cover, although more than half of them showed an ugly black color, but there were still a few grains at the bottom, exuding a delicate smell:
He put two fingers together on the tip of his nose and sniffed, nodded and said:

"Although the quality is average, it's enough for you to use."

Du Dachuan took it respectfully, put it in his mouth without hesitation, and swallowed it with a gulp.

As soon as the elixir entered his stomach, a flush of red appeared on his wrinkled cheeks, as if there was a small stove in his internal organs, emitting a burning sensation.

"Brother Liu Feng, this elixir is so hot in the stomach"

Before Du Dachuan finished his sentence, his throat suddenly started to itch. He couldn't help but bent over and coughed violently, accompanied by a burst of tearing pain, "cough, cough, cough!" He spit out a big mouthful of thick black phlegm.

This mouthful of phlegm gave off a stench, but after spitting it out, he felt much refreshed all over his body, with an indescribable sense of comfort.

It seems that the vitality of youth has returned to this middle-aged body again, and even the wrinkles on the skin have been significantly reduced by the naked eye!

This, this must be the longevity mentioned in the book!Amazing!

Du Dachuan couldn't restrain the excitement in his heart, he knelt down and said respectfully:
"Thank you, brother Liu Feng, for your kindness in rebuilding, I will definitely remember it in my heart."

"No, this is what you deserve. As long as you concentrate on doing things for me, you won't be treated badly."

Liu Feng helped him up and said indifferently.

There are not many finished products out of this stove, only four are usable, Du Dachuan used one, and then Liu Feng pinched one and put it in his mouth, and immediately showed disappointment.

"Sure enough, the effect of the Shengdan is too weak this time, and it's useless to me at all." Liu Feng thought to himself.

Du Dachuan noticed the change in his expression, his heart moved slightly, and he said in a low voice:
"Brother Liu Feng, what other medicinal materials do you need, let me help you collect some?"

"Forget it, all I can use are not available in the market, I will find a way to get it myself later."

Liu Feng shook his head.

Du Dachuan's expression showed disappointment, he hesitated for a moment, and asked tentatively:

"Brother Liu Feng, this elixir should be quite precious, right?"

"expensive?"

Liu Feng couldn't laugh or cry. Before alchemy was lost, it could only be regarded as a basic medicine. After all, there was no advanced modern medical treatment at that time, and princes relied on these things to continue their lives.

After hearing this, Du Dachuan suddenly realized, and said excitedly:

"If it is not expensive, can the formula be adjusted properly for mass production, and the effect on the market must be very good."

Businessmen chasing profits!

After all, Du Dachuan is used to working hard with caravans. When he saw this elixir, he immediately thought of buying and selling, and this elixir really can prolong life as the ancient books said. Couldn't he?
After a little thought, this is a good idea. It is not troublesome to refine the Huisheng Pill. If it is improved, even ordinary people can operate it.

Although the effect may be greatly reduced and the effect of prolonging life cannot be achieved, it should be enough to put it on the market for sale.

The Fuyuan family is now powerful and has secretly controlled several big families. It is inevitable that there will be mistakes by one person alone. If they can cultivate their own power, the difficulty will naturally decrease sharply.

After thinking about it, he handed the remaining two elixirs to Du Dachuan: "I will give you the remaining two. But what I want to tell you is that the elixirs refined by ordinary means cannot be made Life extension, and if you take too much of this pill, the effect will be greatly reduced. So if you really want to sell pills, you must be aware that this pill can only strengthen your body."

Du Dachuan had just received the elixir with a happy face, and he was a little disappointed when he heard the 'bad news' again.
