"Bigu Dan?" The old man stopped the movement of his hand, he turned his head to look at Zhou Ran, then touched his chin, and after a deep groan, he began to think.

And Zhou Ran didn't continue to ask the old man, now the changes in this room have completely attracted her attention, although it has only been about 10 days since she left, but the changes in the old man's room are still very big, a large number of various new types of pills are all placed by him, Zhou Ran picked up a bottle casually on the shelf, opened the cork and could smell the rich fragrance inside, just a few sips and felt that his spirit seemed to become more and more invigorated, I have to say, The old man's talent in this area is still quite amazing, in addition to cultivation, his mastery of the pill can be regarded as quite strong, even in the Beacon Fire Era, I am afraid that no alchemist can reach the level of the old man.

But it's a pity that the old man himself didn't master the corresponding skill of alchemy, so his alchemy ability was completely limited, which is also what he is worried about now, it doesn't matter if the words of the primitive era, even if it is the level of the so-called pills that witches can refine, it is not the same grade as the old man at all.

In the Beacon Era, even if someone has mastered alchemy, but the level that can be played is most likely to be a tie with the old man, and it has to be those highest-level pill masters, but when it comes to the era of qi training, it is not necessarily, if the old man's alchemy is thrown into the era of qi refining, it is estimated that it is the level of the real younger brother, and it is not so difficult to solve this problem, as long as you find a way to keep opening the treasure chest, it will be over, and you can always give the old man a alchemy technique, The treasure of the skill learning path, this thing can be regarded as one of the props that Zhou Ran must get now.

Scratching the back of his head, Zhou Ran looked at the light green powder contained in this stone bottle, it seems that it must be imperative to open a treasure chest in large quantities, and he can only get what he wants through this method, whether it is high-level wood materials, or being able to obtain generals' props, or alchemy, or skill books in the forging book, etc., are very important.

But now we still have to vacate the warehouse to be able to continue this task, so things are back to Bigu Dan, thinking of this, Zhou Ran turned his head to look at the old man, the old man was holding a broken fan in his hand that he didn't know where to find it, and he was facing the pill furnace in front of him, constantly fanning the wind, he didn't even notice that Zhou Ran turned his head to look at him, his eyes stared into the distance, as if he was thinking about something, Zhou Ran didn't bother him rashly, just thinking about it for more than ten minutes, The old man came back to his senses

"There is no problem with the simple Bigu Dan, but I guess that the most basic Bigu Dan will not be of much use to you, "The pill of the Gugu Pill can be regarded as a relatively basic ability in alchemy, even if it is an old man who has not mastered the alchemy skills, in fact, he has a little bit of research on the Gudan, and it is not so difficult to make it."

But as I said before, Bigu Dan, like other things, are all graded, high-grade is naturally more useful than low-grade, and at the same time more rare, more importantly, after the high-grade Bigu Dan is refined, eating one can extend the Bigu time, each practice to one will consume more materials, free up more inventory, and even some of the side effects contained in it will be weaker.

That is to say, taking this into account, if there are conditions, it would be better to refine this kind of high-grade Bigu Dan, whether it is the old man or Zhou Ran, both the old man and Zhou Ran thought of this, the old man stopped, and then shouted outside, and soon a primitive man walked in, he ordered the primitive man, and after a while, the primitive man pushed a small cart and walked over, with a cart full of food.

Zhou Ran turned his head and took a look, all the piles on the top of this cart are meat, fresh meat, is one of the most difficult things to preserve in the territory, if you want to make fresh meat into air-dried bacon, or smoked meat, it takes a lot of time, and it is also a very serious loss of fuel, and if you want to make cured meat, it will consume a lot of salt.

In the primitive era, salt was still relatively scarce, and Zhou Ran only found a natural salt field not far away when he was extremely lucky, which contained a large number of stone-like rocks, which could be successfully used as salt after being smashed and filtered several times, but this road took at least 4~5 hours to walk every day, even if hundreds of primitive people were assigned to be responsible for producing salt, it could only produce more than ten kilograms a day.

It sounds like a lot, but if it is used to make cured meat or eaten separately, it will actually be consumed in a short time, and no matter how Zhou Ran's current territory can be responsible for carrying out various tasks, it is not the number of primitive people who are not warriors, in fact, there are only more than 400, and if more than 100 are divided to collect stone rocks, it is really too exaggerated.

And the entire territory adds up to thousands of people, the daily consumption of salt is not a small number, the only bit that is freed up is all used to make cured meat, so the processing of fresh meat has always been a very difficult problem in the territory, in addition to the daily production of air-dried bacon and bacon, the remaining fresh meat will basically be after hunting, and they are made, and all of them are thrown into the stomach of primitive people within two or three days.

Therefore, it seems to be a bit extravagant and wasteful to use fresh meat to practice Bigu Dan, but in fact, it just satisfies Zhou Ran's thoughts, and the old man doesn't care so much, he gestures a few times in front of the pill furnace, and then pushes forward with his hands together, the golden flame in the top of the furnace twists slightly, and it turns into azure blue in a few clicks, and the azure flame burns for about a quarter of an hour, the old man's hands float on the edge of the pill furnace, and he flies out with a hard slap of the furnace lid, and then a burst of cyan mist emanates from it.

The old man stretched out his hand with satisfaction, and with the support of the internal qi, the pill furnace flew out, about a dozen, only a little thumb-sized cyan pill, and the surface of these pills had white lines one by one.

"That's right, the Qingling Pill has been practiced, but it has consumed quite a lot of materials, if there is this thing, the internal qi cultivation level of the other little guys can be further improved."
