Fantasy: The system takes me to refine the magic formula

"Is this material very precious?"

"The host! On this planet, it is the most precious, but it is common in the fairy world! But there are many things in this person, including 190 heaven-level spiritual grasses, 225 top-level spiritual weapons, several spiritual stones, and fairy world materials. One..."

After listening to it for a long time, Long Tian found that they were all useless things, so he could only say: "I'm sorry, Master, you don't have anything I need! So I can't change it!"

Then Long Tian turned around and came in front of the next person!
The head of the Xianxia faction was a little annoyed, he brought everything by himself, but he didn't even have what this kid needed, this kid didn't even touch the ring, how could he assert that, so he said directly: "Young Master Long! You didn't even touch the ring, so why do you assert that I don't have what you need here?"

"This head, what's your name?"

"I'm sending Sun Yang to Xianxia!"

"Master Sun, in your ring there are 190 heaven-level spiritual grasses, 225 top-level spiritual weapons, and several spiritual stones..." Long Tian explained everything Sun Yang prepared verbatim, making Sun Yang sweat!

"Master Sun, I'm right!"

"Yes! I didn't expect Long Shaoxia to be able to see clearly the contents contained in the storage ring!"

"Yes, I have this ability, Master Sun, the previous ring of Master Hua contained three top-level spirit herbs that I needed, and the ring of Master Qingfeng has a spiritual core that can help me cultivate , so I replaced it, but your things, to be honest, I have all of them, so I didn't replace them with you!"

"So... so it is!" Sun Yang was sweating!
"Headmaster, I have owned your things before, so I can't replace them!"

Longtian began to filter one by one in this way. The things of the five major sects made Longtian happy and surprised. He was happy that among the nine martial arts elements, he collected the spiritual cores of the earth and water series again. Longtian thought that if Luoxi If you need it, you can give it to this girl. To my surprise, I found a dark-type spiritual core in Long Teng's ring besides the wind-type, wood-type, and gold-type cores, so Long Tian took it decisively. !
And in the storage space of casual cultivators, Long Tian actually got a fairy jade hairpin from the hands of a female monk named Juewuqing, this was absolutely unexpected by Long Tian!
"System, is this really a complete fairy artifact?"

"Yes! It's just a low-level fairy weapon, but even so, these human cultivators can't use it. They don't have fairy weapons! Take it!"

"Hehe! It must be taken!"

After a big circle, all 20 Tribulation Pills have been exchanged, and there are also some people who are happy and worried below the stage. The happy people are very excited. The pill in his hand!
"There are still 12 ninth-grade pills that I believe will be helpful to everyone. There is a way to use these 12 pills, that is, if you can't resist when you cross the catastrophe in the future, take them instantly, and you can also let yourself Recover most of your strength! So it is still useful for those who are about to cross the catastrophe and those who are about to cross the catastrophe!"

"Long Shaoxia! I don't know, if we add some more things into it now, if it can make you look good, can we still replace the Tribulation Pill?"

"It's natural, to be honest, there are quite a few of the Tribulation Pills I refined before, except for the 20 in front of me! It's just that everyone, if you don't have what I need, forget it!"

"Long Shaoxia! I don't know what kind of things you need. We really need the Transcending Tribulation Pill. This is life and hope for us!"

Long Tian also knew that it was not easy for these people to cultivate, so he thought about it and said!

"Well, I'll give you some time, everyone help me find these things!" Long Tian took out the spiritual cores of water and wood!

"This is something I collected recently. I don't know if you have seen this thing, but I am researching it. I just made some progress before, and it was broken, so I need a lot to study! I will be in Taoist Longde will stay here for two months. If you find this thing with aura in the outside world, you can come to me to exchange for the Tribulation Pill! This spiritual core is not limited to the wood element, the five elements of the water element , if you have the light system, the dark system is the best, just now I found the spirit core of the wind system in the ring of this master! So I exchanged it decisively!"

"So that's it! Young Master Long asked me to look at this thing again, what exactly is it?"

"I don't know, I'm also researching, but I can feel that there seems to be a very powerful force inside, but I can't use it!"

"Long Shaoxia is right. I also feel the power in it, but there is really no way to mine and use it! If Long Shaoxia can research and achieve results, then we must work hard to search for our own hope of ascension!"

"Okay! Then these 12 pills, do you want to continue to replace them?" Long Tian asked!
"Long Shaoxia! How about we come back after February!"
