This is not a troublesome job, the two of them only tossed for more than ten minutes to complete this task, the old man patted his hand that was still a little fishy, and nodded with satisfaction, the quality of these tiger bones, he had already checked them when he went out just now, and they were worthy of the bones on the body of the quasi-hero unit, compared to the tiger bones of ordinary saber-toothed tigers, but they were quite much stronger.

If you compare it with the medicinal materials prescribed in the blind box, then the quality of these tiger bones is at least a purple light level medicinal material, and after it is air-dried, with some other auxiliary medicinal materials, you can even practice a gold-level pill, that is, a red-level pill.

In addition to the relatively large bamboo shed that he usually used to sleep, the old man also expanded a small bamboo shed in the back, all of which he built himself, which can be called ingenious.

In terms of the level of the old man's carpentry work, it must not be as good as Zhou Ran, whose carpentry ability is basically close to the mastery level, but it is also much stronger than ordinary people, and there are a large number of shelves in this small bamboo shed behind him, and there are a lot of bamboo tubes on the shelves, and there are some small porcelain bottles.

The bamboo tubes are all made by themselves, and the small porcelain vases are sometimes from the treasure chest, and some drugs are opened, and the effect of the drugs is not very much, or the drugs inside are used up, and these small porcelain vases will be collected again.

After all, this thing was very difficult to refine in the primordial era, so people who usually used up the pill would still subconsciously collect these used porcelain bottles.

The porcelain vase and the bamboo tube have the handwriting left by the old man with charcoal, he picked up a bamboo tube and threw it to Zhou Ran, Zhou Ran unscrewed the lid on it, poked his head and looked inside, it contained a large amount of light blue powder.

The old man stretched out his finger and pointed at the wound on Zhou Ran's shoulder, at this time, the wound on his shoulder because of the saber-toothed tiger had basically scabbed, when he activated the characteristics of the dead wood in spring, most of the healing power was used to heal the meridians in the body, ensuring that the meridians would not leave any injuries, and the external injuries were subconsciously ignored by him, so there were still some residues.

Zhou Ran lowered his head and looked at the most corner of the wound on his shoulder, although it was scabbed, there were some traces of slight cracking, and he could see the bright red wound inside, and the old man pointed to the blue medicine powder in the bamboo tube, and he didn't say anything.

But Zhou Ran already understood what he meant, he turned over the lid on the bamboo tube, the old man could be said to be very careful when he made it, and there was a circle of linen under the lid of the bamboo tube.

All of this was opened from the treasure chest before, but the amount of this batch of linen cloth was too small, and it only added up to a few feet, so it was not used to make clothes, but all of them were given to the old man, after all, some medicines need to use these things.

It seems that the old man also made good use of these linen cloths, Zhou Ran tore off a small strip of linen, took some of this light blue powder, and put it on his wound, when the powder touched the wound, there was immediately a cool feeling.

"It's a pity that your wound is almost healed now, so most of the effects can't be shown, this special potion is what I figured out after studying the effect of the healing powder for a long time, as well as the prescription. Basically, the effect is similar to that of healing powder, but there are some subtle differences, its ability to stop bleeding is stronger, but the follow-up healing ability is slightly weaker, and it also has a slight analgesic and cooling effect, which can be regarded as an emergency drug. ”

Zhou Ran nodded clearly, the newly developed medicine of the old man is indeed an emergency supply in a sense, that is, the feeling of a little red medicine drunk during the battle.

It can have a greater effect during combat, and the follow-up healing ability of Healing Powder is stronger, it is more like the kind of special medicine in the game that cannot be used during battle, and must be used in a non-combat state to continuously restore HP.

There are no advantages or disadvantages between the two, it can only be said that they are suitable for different situations, as far as Zhou Ran is concerned, he prefers this special healing powder developed by the old man, after all, as long as he pours a bunch of medicinal powder on his hand during the battle, and pats it on the wound, it can not only stop the bleeding immediately, but even cool and relieve pain.

It is important to know that the effect of cooling and analgesic is very important, even if it is a warrior with a will like steel, it is very likely that the pain will cause deformation of movement.

This is not because their will is not strong enough, but purely physiological reasons, pain can cause a series of side effects such as muscle spasms, so there is no way to avoid deformation of movements, and the special effect of cooling and analgesia can play a role at this critical moment.

"Sir, what is this drug called? Is the yield high? Do I need any special production methods or anything? Zhou Ran was also quite curious, after all, generally speaking, most of the medicines that could be refined by the clay medicine furnace were pills, and no matter how bad they were, they were also ointments.

Powders or powders like these, as well as medicines such as granules, are usually of the crude type, where the sun-dried herbs are put in a small stone bowl, crushed into powder with a pestle, and then mixed together.

"It's called hemostatic analgesic powder, or simply called hemostatic powder, it didn't take me much time to research, and it wasn't too difficult to make, but it was very troublesome in terms of drug proportioning. It needs to use a total of 6 kinds of medicinal materials, two of which are the main drugs, 4 are excipients, and the ratio between each needs to be accurate to half a dollar. ”

One dollar is 5 grams, half a dollar is 2.5 grams, Zhou Ran now admires the old man's pharmaceutical technology, 2.5 grams in the absence of accurate weighing tools, the old man can accurately compare, and according to this ratio made so many hemostatic powder, I have to say that his ability to control drugs is too strong.

That is to say, the old man has no talent in this area, and at the same time, he has no adventures, and he has not been able to learn the pharmaceutical ability that can be recognized by the system, otherwise his skills would at least have to be evaluated as an expert.

"As for the types of medicinal materials needed, it's not very rare, and the medicinal materials that come out of the treasure chest are barely enough for the old man to use for a while, if all of them are made, the weight of your bamboo tube can probably make about 15 to 16 tubes, which is not too much."

Zhou Ran weighed the bamboo tube in his hand, the weight was about 100 grams to 120 grams, 15 to 16 bamboo tubes, in fact, it was really not much, after all, there were so many wild stone spearmen in the territory, most of them would be a little injured when they went out to fight, and everyone had to prepare some, and it was estimated that all these hemostatic scatters would be used up in three or two battles.
