In fact, this kind of thing is very normal.

For practitioners, the foundation is very important. Often times, the foundation is firmly established, and then some complicated things can be easily calculated through these foundations. This is the same as the single operation of addition, subtraction, multiplication and division and the later mixed operation.

Red blood grass is the most common medicinal material in the medicinal world, and its effect is also very common. Alchemy through the use of red blood grass can be said to be a very simple thing, or it can be said to be a very difficult thing, but all the alchemists who can use red blood grass to make alchemy are very solid alchemists.

The realm of the old man is already very high, and the level of refining pills is naturally very strong. But maybe because of his foundation, some are not very solid, or that the old man directly ignores some of these simple things, which he thinks he already knows.

But in fact, the old man still has a lot of unclear. If the old man could think of refining the pill through simple medicinal materials similar to red blood grass, then the things that the old man has encountered now that bother him will probably disappear!

"You... how did you think of refining pill from red blood grass?" After the old man got rid of some of the difficulties he encountered, his eyes widened suddenly, his eyes gleaming at Lu Chen, then It looked like he wanted to swallow Lu Chen directly.

"What's unexpected. Since red blood grass is a kind of medicinal material, and it has such a remarkable effect on healing wounds. Then adding some things will definitely be able to refine some medicines suitable for practitioners. .Unfortunately, the red blood grass is too common, and it is too wasteful to use it to refine the pill!" Lu Chen said, shaking his head.

"Then how did you think of using medicinal materials such as Yuhanye and Fenglongcao to assist in alchemy?" the old man asked again.

Hearing the old man’s question, Lu Chen was obviously a little impatient. The reason why Lu Chen used these two medicinal materials to assist in alchemy was completely because he used the most basic common sense in alchemy, Yin and Yang to reconcile. I don't understand the truth!

"Red blood grass needs fire element, which means he is masculine, while Yuhan Ye needs water element, he is yin. Adding the two will cause unpredictable consequences due to the repulsion of water and fire elements. , But Fenglongcao is something that can make the two become stable.

After adding red blood grass and feather cold leaves, when the two are completely refined and are about to merge together, immediately add the juice of Fenglongcao to calm the explosion of the two, and wait until the two slowly After fusion, add a little bit of Tianquan water, and that's it! "

"Huh! Wait, what are you doing with Tianquan Water?" the old man asked in a puzzled way.

"Red blood grass and Yuhan leaves, although they are fused together because of the sap of Fenglongcao, the repulsion of the two still allows the water in them to be repelled by each other, and then evaporated by the pill fire. Do you think such a thing is delicious when it becomes a pill?" Lu Chen said contemptuously.

Uh, in fact, to put it plainly, the reason why Lu Chen added Tianquan water was to make the red blood pill (the pill named by Lu Chen after refining with red blood grass, feather cold leaf and Fenglong grass!) taste, It becomes more refreshing. Hey! Lu Chen is indeed a foodie!

The old man naturally understood Lu Chen's purpose and rolled his eyes speechlessly, but in his heart, he agreed with the step that Lu Chen finally joined Tianquan Water. Actually speaking. Old man, no, it should be said that all alchemists are actually foodies.

Although the old man has learned a lot from Lu Chen about the red blood grass, after all, the red blood grass belongs to the most basic herbal medicine. Naturally, the old man cannot be because of what happened on the red blood grass. , Let Lu Chen pass the first test so easily.

"What is this again?" So, the red blood grass in the old man's hand changed again. However, the color is still red, but the appearance of the plant has slightly changed. The blood red grass just now looked like a red dog's tail grass, but the current plant looked a little weird.

The plants in the hands of the old man have countless roots, and each of these roots is bent. Although it looks very soft, it is actually very hard and very sharp. It is these sharp and hard ones. The roots are formed in a circle and are firmly rooted in the ground. This prevents accidents from happening to the huge plants that do not grow on the roots in harsh environments.

Although the plant on the upper part of the roots is huge, like the tail of a carp, starting from the roots, it becomes wider and wider, and when it comes to the second half, it separates from the middle and becomes a V-shape. At the top, there is a circle of small filaments like stamens.

This medicinal material, called fishtail grass, is named because its shape resembles the tail of a fish. The most important part of fishtail grass is the plant that resembles a fish tail. This part is not very smooth, but hairy.

If you have a magnifying glass, you can use a magnifying glass to see that these fluffy, piled-up things are actually similar to small flowers. Each of these small flowers has five fiery red petals. It is because of these that the fishtail grass looks so fiery red.

If red blood grass is very common, then fishtail grass is extremely rare.

Fishtail grass generally grows in deep water, at least 10,000 meters below. Another feature is that there must be an active volcano near the fishtail grass. And the day when the fishtail grass matures is the moment when the active volcano erupts!

It is for this reason that it is very difficult to get fishtail grass. Moreover, the growth of fishtail grass is very difficult. In addition to absorbing the huge fire element, it also absorbs various toxic substances. Those little flowers are actually equivalent to the poison sac of the fishtail grass. The toxins are all stored in those places.

There are two functions of fishtail grass. It can help people detox at a time and absorb the toxic substances in the human body cleanly. However, this requires time when the fishtail grass is alive, but the disadvantage is that if the person repairs poison , Then it is very likely that the poison that he has cultivated for many years will also be absorbed by the fishtail grass directly, making it a waste person!
