For example, a prescription called "Yangqi Decoction" is written in the book: decoction and decoction of medicinal materials such as ginseng, Polygonum multiflorum, Poria cocos, cinnamon, decoction, violet flowers, and Yang leaves in a certain proportion.

But the mysterious reminder shows that if you add "Cordyceps" and "Fire Yang Stone" to this prescription, the efficacy of the medicine will double.

After reading the "Medicine and Food Collection", all the prescriptions in it are prompted to be improved. If you add medicinal materials based on the prescription, or change the proportion of medicinal materials, it will be more effective than the original medicine.

"Your golden finger looks very difficult!"

The ability of this mysterious prompt seems to be very powerful. It seems that you know the information about everything in this world, and can scan everything you see in a popular science scan or even perform some optimizations.

It feels like in the game, running a special script.

Then, Chen Chang'an picked up the "Yu Fei's Record of Cultivation" and read it. The book records Yu Fei's many experiences in the cultivation world, as well as his various insights and precautions on cultivation.

The mysterious prompt affirmed that some of Yu Fei's insights were correct, and also pointed out that some of the insights were wrong.

Chen Chang'an decided to take the prescription and test it after going back, and make several original and improved versions of the medicine to test the effect.

If the same medicine has better effect in an improved version, it means that your gold finger does have an incredible "optimization" function.

If this is true, then the improved version will definitely be better, whether it is the prescription or the exercises.

…………

A few days later.

There were several kinds of medicines placed in front of Chen Chang'an, including medicinal soup, medicinal powder, and pills.

There are two servings of each medicine, one is made according to the prescription in the "Medicine and Food Collection", and the other is made according to the mysterious prompts.

After thinking about it, I was safe, I would like to find some animals to test the medicine.

So he locked the door and headed straight to the market.

There are chickens, ducks, fish, sheep and geese at the market, and there are all kinds of animals to eat. In the end, Chen Chang'an planned to buy a few rabbits to go back for experiments.

When he looked at a rabbit, he was stunned-

[Hareal Spirit. A white rabbit that has just started to recognize but has not yet transformed.]

Yu Fei mentioned in his book "Yu Fei's Cultivation Record" that there are actually many types of monsters, such as monsters, monsters, monsters, monsters, etc. The first step for them to become monsters is to gain a human-like mind consciousness. This step is called "opening consciousness", and then you can become a human through practice. This is called "transformation".

Ordinary birds and beasts like rabbits, chickens, dogs, and cows will open their wisdom because of some opportunities. At this time, they are already considered as monsters. However, before transformation, such monsters are usually not dangerous.

Chen Chang'an squatted beside the cage and carefully observed the demon rabbit. He found more than a dozen rabbits, and only one rabbit was crying, looking very pitiful.

At first the rabbit only cared about himself and cried. When it found that Chen Chang'an had been looking at it, his eyes suddenly showed a look of fear and quickly shrank into the corner.

"Boss, I want this rabbit!"

Chen Chang'an pointed at the rabbit spirit and said.

"Okay!"

The rabbit seller was a middle-aged hunter. He pulled out the rabbit spirit from the cage, tied it with a rope and handed it over to Chen Chang'an.

After paying, Chen Chang'an took the rabbit and left.

The rabbit, bound limbs, struggled all the way, with a look of pleading in his eyes. It knew that humans wanted to eat it, but it already had the intelligence and would be afraid of death. It was afraid of death and was unwilling to die just like this.

Shortly after Chen Chang'an left, a young woman wearing a white cloak and a hat rushed over.

Her eyes were searching around, and her nose was slightly shaking, as if she was discerning the smell, and then chased in the direction Chen Chang'an left.

PS: This passage is added later. Let me give you some popular science on the realm of this book. The current outline sets from small to large: practicing qi, nourishing elixirs, transforming infants, entering the spirit, returning to the emptiness, and peeping into the sky... Each realm is divided into one to nine grades.
