"I'll go, I'm fine anyway, Ah Jin and I are a little taller, and we will be faster along the way, and my storage space is a little bigger, maybe I can travel lightly."

Hearing Wan Qiyun's shallow finish, Ling Yulin's eyes lit up, and his frowning brows stretched a little.

"Okay, Yun Qian, this matter will be handed over to you, I will let people collect supplies now, do you have any opinions?"

In the past, when Wan Qian Yunqian was still a gentleman, Ling Yulin never looked down on Wan Qian Yunqian, or ignored her, and would ask her opinion if there was anything, not to mention that Wan Qian Yunqian was out of the country now.

In his heart, Wan Qian Yunqian was even more reliable than Ling Qinghan.

After all, after so many years of forbearance, his temperament was far from being comparable to Ling Qinghan's.

"Yes, I can refine the elixir and exchange it with those who have supplies in the Imperial City, and those outside the Imperial City can also do it. Bartering, pills are generally the most basic to improve cultivation, and there are also those that can repair wounds, if there are other requirements, you have to increase the chips. There is also your storage bag, I also want to borrow it, so that Ah Jin and I can travel lightly and do not need someone to escort the supplies, which can also save a lot of manpower and material resources."

Wan Qian Yunqian had already thought about a lot of things on the way here, so she waited for Ling Yulin to ask her, and now she came out in one go.

Except for Gong Chenjin, everyone else was contemplative, and what they didn't agree with was the previous proposal.

"Yun Qian, we all know the effect of your elixir, if you want to barter for things, do you have to ask for more, and if you can ask for it, the standard can't be lower."

Wan Qi Jingqiu frowned and said, they have all used Wan Qi Yunqian's elixir, and they were all surprised by the good effect, so how many materials to exchange for a pill is also a difficult problem.

"Let's talk about it, I'll go around the city later, by the way, do you know what this thing is up and down?"

Wan Qian Yunqian doesn't care too much about those, there is no shortage of herbs or anything, and what is wasted is just time and mental power.

Ling Yulin nodded, and then came up with a lot of technical terms that surprised Wan Qian Yunqian.

"It's called snow, and this is what the Great Elder found in an ancient book. In the book, snow is a natural phenomenon, which is conducive to the growth and development of crops, and has a good thermal insulation effect, which can protect plants from frostbite in the cold winter, and can also provide a good water supply for vegetation. In addition, because the heat conductivity of snow is very poor, the soil surface is covered with a layer of snow cover, which can reduce the transmission of soil heat and block the invasion of cold air on the snow surface, so the crops protected by snow can safely survive the winter. In addition, snow cover stores water for crops and enhances soil fertility."

At this point, Ling Yulin paused, "It also says in that book that there was snow thousands of years ago, normally in December, almost every year, but a big event happened a thousand years ago, and it hasn't snowed since then."

Listening to this, Wan Qiyun inexplicably felt a little familiar, a sense of déjà vu, but he couldn't think of anything, and in the end, it came down to the fact that the previous words were too professional.

"It's good to know, we have to get this news out quickly, so that everyone has a bottom in their hearts, so that people's hearts will not be turbulent, and then there will be trouble."
