The rest of the forest species are all similar to the graphics and descriptions of the spirit grass. "What is this?Compendium of Materia Medica in the Immortal Cultivation Realm?" Since what was recorded was not an exercise, Nie Fei was slightly disappointed. But after a while, Nie Fei thought about it, and suddenly his face was full of joy again. He suddenly realized that this "Hundred Herbs for Cultivating Immortals" is simply perfect for his current self.

He was new to this world, and he was not familiar with it. So far, the only skill he has been able to speed up his cultivation process is the various chemical methods he has mastered. These chemical methods need to be different according to the different materials and adopt different methods, which requires a very familiar understanding of the characteristics of the materials. Isn't such an illustrated book, with not only graphics but also descriptions, to provide oneself with regard to the characteristics of various plants?

Thinking of this, Nie Fei couldn't help but smile and firmly held the jade card in his hand. "Haha...... This illustrated book, perhaps, is not very useful to others. But for me, it's more useful than any exercises. Unexpectedly, I actually got such a treasure. The more Nie Fei thought about it, the happier he became, and he couldn't help but put the jade card to his mouth and kiss it.

......

Nie Fei began to read the illustrated book carefully. Each of the plants on the illustrated book has certain characteristics and effects, but many of them are not available to Nie Fei now. When he saw the seventh plant, his eyes suddenly lit up, and he couldn't help but look at it carefully many times. After reading it, he detached his consciousness from the jade plaque and thought about this plant.

This plant is called the sunflower, and the petals of the mature flower body are very large, ranging from seven to eleven petals, but they must be odd, that is, seven, nine, or eleven petals. The color of the flowers is mainly black, mixed with dark red, and it must be more black and less dark red, otherwise it is not a sunflower. This flower is often made into a cold pill and a cold flower pill by the Dan master to enhance the cold energy contained in the aura. It stands to reason that this flower itself is cold, and after making zuò out of the elixir, it should be able to greatly increase the cold of the user. But this is not the case, for some reason, the elixir made from the main material of the sunflower does not greatly improve the cold. Not only that, this kind of elixir can not be taken indefinitely, if it is taken too much in a short period of time, it will often cause the aura in the body of the immortal cultivator to be chaotic, and the aura will bump up and down in the body, which is a typical symptom of going mad. Although this elixir has all kinds of drawbacks, there are still people who take it for a long time to increase the cold in the body.

Others don't know why this elixir made from sunflowers has these drawbacks. But Nie Fei only looked at it once, and he already had a rough idea in his heart.

This is still far from the sunflower itself. To be exact, it should have a lot to do with the environment in which the sunflower grows. It is cold from the sunflower itself, but the environment in which this flower grows is extremely special, and it grows in a hot place all year round. If the temperature of the environment is a little colder, the flower will not survive, especially if it is located next to a volcano. Isn't it strange that a flower that is cold in itself, but grows in a very hot place, and its wonderful Cheng dù cannot be overstated.

Nie Fei didn't know why the growth environment of this flower was so harsh, but he knew that growing in a hot place, this kind of flower would inevitably absorb some heat, but this heat was cleverly hidden and could not be discovered. But this heat must be stored in zài.

This is a good explanation for why the elixir made from this flower has little effect on the cold after taking it. It's strange that there is heat and cold that clash with each other and merge with each other, and that the elevation is greater. This kind of heat and cold, when you take less food, the reaction is not obvious. Once taken in large quantities, in a short period of time, cold and heat cannot be fully integrated, and there will inevitably be conflicts, and the more you take, the more significant this conflict will be. It's no wonder that taking too much food will cause the aura in the body to be chaotic, too much cold and heat, and the body has become a battlefield for cold and heat conflicts, how can the aura not be chaotic?

"If you can separate the cold air in this flower, without a trace of heat, it is equivalent to pure cold. If you continue to take it, will the cold attribute in the aura be significantly improved?" Nie Fei thought.

In fact, the reason why Nie Fei had this kind of thought was from his Water Thousand Illusion Technique. Water Thousand Illusions is not a simple illusion, but has a certain degree of aggression and can turn fiction into reality. What is meant by turning the void into reality is to stimulate the aura and condense the illusion formed by water vaporization. In fact, it is a bit simple to say, why can the aura be stimulated, so that the water vapor can be condensed into solid? Just because of the cold in the aura, the water vapor can be condensed into ice, and the vapor into ice is to turn the void into reality.

Therefore, this cold qi has an extraordinary significance for the practice of water thousand illusions. The deeper the cold air, the more handy it is to use it, and the more it can give full play to the ever-changing characteristics of the water thousand illusions.

Since Nie Fei had this thought, he couldn't sit still anymore, and he couldn't wait to immediately find a sunflower to test it to see if he could separate the cold air.

However, he did not have any sunflowers on hand, and although there were many herbs planted in the yard, none of them were sunflowers. Since you don't have it in your hand, you have to look elsewhere.

Fortunately, this is not an uncommon thing from sunflowers, there is a shop in Tianling Fort that specializes in selling various herbs, Nie Fei decided to go to that shop pù to take a look, maybe there is sunflower tweed in that shop. In addition, he didn't have a single Xie Ling Grass on hand, so he happened to go to the store to buy it.

......

The shop that sells medicinal herbs in Tianling Castle is called Li Ji Old Shop, located in the heart of Tianling Castle, and is an old shop that has been passed down through generations.

Li Ji's old store is not big, there are only two bungalows, but he is the only one who sells medicinal herbs in the entire Tianling Fort, so the business is not bad. And because the shopkeeper Li Laoshi has been from Tianling Fort for generations, everyone in his hometown knows him, and the owner of the castle, Lu Bowen, treats him well, which makes Li Laoshi very satisfied.

After noon on this day, Li Laoshi, the owner of Li Ji's old shop, was sitting in the middle of the shop, when he suddenly saw two people coming in from outside the door. Seeing that these two were extremely thin, one tall and one short, and then looked at the faces of the two, Li Laoshi couldn't help but shiver. There was a hint of miserable green in the complexion of the two people's faces, and the two of them had expressionless faces, which suddenly looked gloomy.
