Cultivator in the Last Days-Chapter 45: Pharmacy

Chapter 45: Pharmacy
"Meow." <Where are we going now, Master?>
Xiao Mao peeked out slightly from Yu Shi Lan’s pocket. After getting further away from the temporary shelter, there was no need for Yu Shi Lan to worry so much about the others waking up from her sneaking around.
But years of staying in the cultivation world still made her wary and her steps were extremely light.
"To the pharmacy," Yu Shi Lan replied.
"Meow?" <Are you sick, Master?>
Xiao Mao was dumbfounded and quickly checked their soul connection through the soul contract. He found that Yu Shi Lan seemed to be perfectly fine, but if it was just a small injuries, it would be impossible to detect through this contract.
"What are you thinking, Xiao Mao?" Yu Shi Lan was speechless and poked the little cat’s forehead. "I’m going there to find some raw medicine and also supplies that I might need for the sake of my health."
The common medicine such as cold medicine and fever medicine would be important too, so Yu Shi Lan planned to stock them up.
While she might not need them, she could trade them with the official shelters in the future.
Well, this is basically taking advantage of the situation.
But Yu Shi Lan didn’t care too much.
Each took what they needed and Yu Shi Lan didn’t believe that these people would have time to take over these resources in the next few days. Because of the weather in the near future, it would be hard to keep most of these supplies in good condition.
"And most importantly, I need to keep alum, chlorine dioxide, and sodium hypochlorite that are used to purify water."
"Meow?" <Water?>
Yu Shi Lan nodded.
"I’m sure you have seen through my memory and even though I might not plan to stay in this world for such a long time, the water resources will be exhausted sooner or later. At that time, these materials used to purify water will be even more precious."
Alum precipitates the debris, bacteria and parasite eggs in the water, and the latter two are then disinfected, sterilized and virus-killed, which can solve the drinking water problem to a large extent.
This was the knowledge that Yu Shi Lan learned in her first life when some people managed to find one of these three materials and handed it over to the base only to receive a large number of contribution points.
It was then they explained the science to her.
She also had some understanding of this matter.
"Meow?" <How about food and other resources?>
Xiao Mao had never understood these things because they didn’t exist in the cultivation world. Besides, food problems were basically something that only mortal cared for. After they stepped on the cultivation world, they would slowly but surely forgo eating.
Because it was really unnecessary.
Of course, the Qi Refinement Stage still couldn’t stand not eating at all. They still needed the energy contained in food for them to practice.
After they advanced later, the food they consumed would be food contained Qi that was beneficial for their practice. Those were more useful compared to ordinary food that could only be used for taste on their mouth but had no other function.
Many cultivators even didn’t want to eat because they felt that it would waste their time purifying it after eating.
Well...
Yu Shi Lan felt that it was indeed rather extreme.
"Hmm? I’ll collect some rice, sesame, soybeans, and probably sugars," Yu Shi Lan explained her plan.
"Meow?" <Why?>
"Because under normal circumstances, rice can be stored for five to ten years without going bad, soybeans can be stored for twenty years, sesame can be stored for sixty years, and sugar is even more terrifying, it can be stored for thousands of years without deteriorating."
It was also for this reason that the bases chose to store them back then.
Yu Shi Lan managed to gain this information through asking around when she was in the base at that time because she was curious.
Thanks to this, she still has some basic knowledge of what resources are important.
"Well, I can also collect instant noodles. They’ll be hard currency later along with wine and cigarettes."
But considering that her space was limited, Yu Shi Lan had no interest to take on some things that were too hard to carry.
Human’s survival was not of her concern.
She cared more for herself.
It was precisely because of this that Yu Shi Lan could stay calm when she saw other people suffered in front of her.
She had seen too much.
And the ending of those who were soft hearted has never been good.
If she became momentarily soft hearted because of what she had seen, she would only repeat the tragedy in her past and this rebirth would have no meaning.
