The medicinal materials written by Lu Yu are naturally the materials needed to refine the Innate Spirit Pill and the Guyuan Pill, although most of the medicinal materials required by Lu Yu have been obtained in the treasure house of Aotian, but there are still some medicinal materials that I don't know if they are common or not, and Lu Yu does not have enough time to find them, and now it is undoubtedly the best choice to buy them directly at the Supreme Auction House.

Of course, Lu Yu also wanted some other medicinal materials, not because Lu Yu was afraid that his own pills would be leaked, but because Lu Yu also had to collect some for other pills, and when the time came, he would have to look for them everywhere like now.

"By the way, Elder Li, I don't know if you know where the Danfang appears?" Lu Yu asked again after handing over the written list of medicinal materials to Elder Li.

Elder Li took the Dan Fang handed over to him by Lu Yu, and looked at Lu Yu with some doubts, "Dan Fang, what do you want Dan Fang to do? Although I have some in the Supreme Auction House, they are all some broken Dan Fang, which don't play a big role!"

Regarding Elder Li's question, Lu Yu definitely didn't answer truthfully, "Elder Li, isn't this the kid's master?" Let me come out and try my luck and see if I can get some Dan Fang, the family master is quite good at studying this aspect!"

Lu Yu directly used his unwarranted master to fool this question.

"Quite researched!?" Li Lao was a little shocked when he heard Lu Yu's words, usually people only specialize in alchemy or refining, not only that, but just cultivating alchemy or refining will take decades, and this Lu Yu's master will choose to cultivate with alchemy and refining tools, if Lu Yu's master is not a fool, he will definitely be a peerless genius.

And genius is exactly the talent that the Supreme Auction House lacks now, not to mention that it may be a peerless genius, which makes the Supreme Auction House start to win over for a year.

"Since it is what Lu Yu Xiaoyou and your master need, then you wait for a while, I will go and ask the governor for instructions, and then I will send all the medicinal materials you need!" Li Lao glanced at the list of medicinal materials written by Lu Yu and said to Lu Yu, and then walked out and went to prepare medicinal materials.

After Li Lao left, Lu Yu breathed a sigh of relief, needless to say about the many excuses he had prepared before, all of which Lu Yu had to thank them for creating an unwarranted master for himself, so Li Lao saw what Lu Yu needed and didn't ask Lu Yu why he needed to prepare directly, not only that, but he could also get a few more Dan Fang from the Supreme Auction House, and this trip was already worth it.

As for why Lu Yu needed the pill, although Lu Yu already had too many pills on the Medicine Emperor's decision, there were only a few that he needed or could use now, and there were many of the pills on the pills that were extremely cherished, and they were not simply available.

Lu Yu also thought that his current alchemy technique could only be learned from scratch, so Lu Yu still wanted to refine some other pills and practice his hands first, saving himself from wasting all these cherished medicinal materials.

After Li Lao went out, Lu Yu felt bored, no matter where it was, he just sat cross-legged and began to cultivate, Lu Yu's cultivation method is too much, there are also twelve emperor decisions, each of which is the top level of exercises, and each cultivation method is still a little different, but fortunately, the mixed yuan method can completely control the twelve emperor decisions, so Lu Yu's cultivation world has not been affected by anything.

Just when Lu Yu was practicing, Li Lao also returned to the room with the pill and the medicinal materials written by Lu Yu.

As soon as Li Lao entered the room, he saw Lu Yu cultivating cross-legged, so he didn't disturb Lu Yu, but he had some more praise for Lu Yu in his heart.

Time passed minute by minute, and although Lu Yu only felt that he had been cultivating for a while, it had already been a full hour and a half.

And Li Lao also waited in this room for more than an hour.

After Lu Yu opened his eyes, he saw Li Lao with his eyes slightly closed on the side, Lu Yu was a little embarrassed, but he didn't expect to let Li Lao cultivate the Dharma for himself.

"Boy, thank you Elder Li!" Lu Yu got up and bowed to Elder Li after seeing Elder Li, and after Elder Li heard Lu Yu's voice, he opened his eyes, "You kid, it's okay, let's talk about business first!"

Li Lao said, with a wave of his hand, a soft force helped Lu Yu up, although, Li Lao continued to say to Lu Yu, "Lu Yu Xiaoyou, although I have some Dan Fang in the Supreme Auction House, I can't just hand it over to others at will." ”

Lu Yu also knew that he would not get the Danfang so easily, so he asked Li Lao, "I don't know if Li Lao has any rules, if it is suitable, I can come down for my master first." ”

"Okay! Then since that's the case, then I'll say it!" Li Lao paused for a moment, and then said to Lu Yusuo, "I hope that your master can join the Supreme Auction House and become the guest of my Supreme Auction House!"

"This!?" Lu Yu's face was a little embarrassed, he didn't have a master at all, where could he get one to join the Supreme Auction House!

Li Lao looked at Lu Yu's somewhat embarrassed face, and knew that this might not be possible, but Li Lao's purpose was not Lu Yu's mysterious master, but Lu Yu himself!

Lu Yu's mysterious master, it is excellent to be able to win over nature, but as long as he is a cultivator who lives in seclusion, how can he be willing to go out of the mountain easily, so Li Lao's goal was locked on Lu Yu from the beginning, he believed that as long as Lu Yu was tied to his side, when Lu Yu was in trouble in the future, how could his master stand by and watch.

"This ...... Old Li, let's wait for me to go back and ask the tutor, before I decide!" Lu Yu replied for a long time.

And Lu Yu's answer was also expected by Li Lao, "Since Lu Yu Xiaoyou wants to go back and ask the master, then let's take our sincerity with us!"

Li Lao said, took out three Dan Fang and a storage ring and handed them to Lu Yu, "These are three Dan Fang, two of them are not rare, and one of them is broken and can't be cracked, but it must be a peerless Dan Fang If Xiaoyou doesn't dislike it, bring it over!"

"That kid thanked Elder Li on behalf of the family teacher!" After Lu Yu took the Danfang and the storage ring, his heart was full of joy, and then Li Lao continued to say to Lu Yu, "Lu Yu Xiaoyou, this storage ring contains the medicinal materials you need, and we have also prepared some of the medicinal materials in these three Danfangs, I hope Xiaoyou will talk to your master when the time comes!"

Although Li Lao didn't have much hope for Lu Yu's master, he still had to give it a try, what if he succeeded?

For Li Lao's enthusiasm, Lu Yu also knew that everything was due to his unwarranted master, Lu Yu was too lazy to be hypocritical, he didn't have much of it, and now that someone sent him so many good things, how could he not accept it? Anyway, when the time came, he directly told Li Lao that his master was unwilling to go out of the mountain.

"Everything has already been received, Elder Li, the kid will go back to see the master first, if the master is willing, the kid will definitely bring back this good news earlier!" After Lu Yu got what he wanted, it was time to leave, otherwise there would be a lot of time wasted on this meaningless matter.

"Lu Yu Xiaoyou, go slowly!" After Li Lao finished speaking, he walked out with Lu Yu, and after arriving at the door, Li Lao pointed to a tall building in the city, "Lu Yu Xiaoyou, there is Juyun Tower, and next to it is the registration office of the Deserted City Billboard, if you plan to hit the top ten of the Deserted City Billboard, you have to go there to sign up first!"

Lu Yu looked at the place where Li Lao pointed and saw the tall building, "The kid thanked Li Lao for his guidance and said goodbye!"

After Lu Yu finished speaking, he walked towards Juyun Tower, and after Lu Yu left, Lu Yu saw the black-robed man in the room before suddenly appeared beside Li Lao.

"Elder Li, do you think his master might resolve the crisis of my Supreme Auction House?" But this time, the voice of the black-robed man changed to a woman's voice.

"Miss, we can only gamble now, and we can only do our best to find some talented alchemists or refiners in five years, if we can't find it, it may be that the sky is going to destroy my Yun family!" Li Lao looked at the sky and his face was a little sad.

"That's it!!" A wry smile appeared on the corner of the mouth of the person who was called the eldest lady by Li Lao, "Li Lao, you don't have to deliberately look for an alchemist or a refiner in the future, and it will save them harm, if you can't help it, I will follow that person!"

"Miss......" Li Lao wanted to say something more, but the black-robed man disappeared from Li Lao's side.

Li Lao looked at the place where the black-robed man disappeared, and showed a helpless wry smile, "Even if you are called a peerless genius, in the end, you can only make wedding dresses for others...... Miss, life!"

After Li Lao finished speaking, he turned around and walked into the Supreme Auction House.

After Lu Yu left the Supreme Auction House, he walked towards Juyun Tower, fortunately, the Supreme Auction House was not too far from Juyun Tower, and after a quarter of an hour's kung fu Lu Yu arrived next to Juyun Tower, and after seeing the registration office of the Deserted City Billboard, Lu Yu walked over directly.

There are not many people in the registration office of the Deserted City Billboard now, and now that the competition is approaching, those who want to participate have already registered and gone back to step up their cultivation.

"I want to sign up!" Lu Yu went straight to the registration office of the Deserted City Billboard to register, but the people at the registration office of the Deserted City Billboard were all lazy and had no vitality!

"Ao, sign up, what sect?" "There is no sect!" Lu Yu replied truthfully, "Ao, loose cultivation!" The people at the registration office didn't bother to pay attention to Lu Yu.

"The registration fee is three lower grade spirit stones! If not, get out!" The attitude of the registration office made Lu Yu hot, but it was not okay not to sign up, so Lu Yu took out three lower grade spirit stones and smashed them on the table at the registration office.
