As soon as he walked out of the fire room, Yu Xiao bumped into Zou Lao head-on.

At this time, the latter frowned slightly, with a strange expression, as if he had encountered something tricky, and he was a little surprised to see Yu Xiao actually come out of the lowest level of the Earth Fire Secret Room.

It's not that he doesn't think that Yu Xiao is a little ignorant of not listening to his advice, but he thinks that this guy should be a novice who is new to the way of refining weapons, and he doesn't know that it is best to choose a more stable earth fire when injecting spirit into magic weapons.

The ground fire secret room of the Wufang Building, the area near the upper floor, the general ground fire is relatively stable, and the closer to the ground fire area, because the closer to the surface of the ground fire, the temperature will be higher, and the flame will be more irritable, difficult to guide, and there is a high test of the technique and technique of the soul.

He saw that Yu Xiao was just a cultivator in the late stage of Qi refining, and he bought some fire essence qi needed for spiritual injection, thinking that it should only enhance the power of his magic weapon, and he didn't need any complicated operations, so he kindly reminded him.

Now it seems that most of Yu Xiao's spiritual injection results have failed, and it just so happens that he can also take the opportunity to earn another spirit stone from the other party.

Just as Zou Lao was about to ask if the other party still needed the fire spirit qi, Yu Xiao suddenly explained: "Well, the junior just felt that the flame temperature in the secret room above was not enough, so he came to the lowest fire secret room. ”

Hearing this, Zou Lao didn't suspect anything, but the strange expression on his face was even worse, and he muttered again and again: "It's really unlucky, how can many people today reflect that the flame temperature of the earth fire is much smaller than before, and they have run away with many guests in vain." ”

When he said this, there was still a trace of flesh pain on his face, and when he saw that Yu Xiao was still standing in place, he didn't mean to leave, and he didn't associate him with this matter in his heart, but casually found an excuse to prevaricate with a straight face:

"Ahem, I can only say that you are unlucky, recently the ground fire under the Wufang Building has entered the dormant stage, and the firepower has dropped significantly, and there is no way to carry out various refining and alchemy operations, you can come back after a while."

Yu Xiao naturally wouldn't say that the reason why Earth Fire became like this was all related to his practice in the Earth Fire Secret Room, otherwise Zou Lao Tie would definitely ask him to compensate for his losses.

Thinking in his heart, he said before that there were a lot of Dan Fang for sale in Wufang Building, so he planned to try his luck, so he said: "The junior has actually completed the infusion of magic weapons, and I want to find something to do when I have nothing to do recently, I want to ask Zou Lao, what Dan Fang is for sale in Wufang Building." ”

At this time, Zou Lao was still feeling depressed because he had lost a lot of guests today, but now after hearing these words, he suddenly felt like he had been beaten with chicken blood, his eyes lit up, and he felt more and more that Yu Xiao was a little rich man, and immediately changed his smiling face; "I can't see it, Xiaoyou can actually do alchemy, so what kind of pill do you want?"

"The juniors have some research on alchemy, and they want to find some pills that test their skills to practice their hands, so I plan to see what pills the seniors have here before making a decision." Yu Xiao didn't say it clearly, pretending to be an ordinary alchemist.

"So that's the case, then Xiaoyou has to choose carefully, some pills look completely different from the actual refining, and generally not very experienced alchemists will fall behind." Zou Lao's eyes narrowed slightly, and his face was full of money.

He didn't doubt the truth of Yu Xiao's words at all, only when he met a fat sheep again, he led him towards the top of the passage: "This is not the place to talk, go up first and talk about it." ”

"The essence of the way of alchemy is that practice makes perfect, as long as you refine more, you are not afraid that you will not be able to refine the finished pill, oh yes, who did Xiaoyou's alchemy learn from?"

"The juniors are self-taught, and after studying some alchemists' notes, I feel that it is not as complicated as I imagined."

"Xiaoyou, if you think so, you are wrong, the way of alchemy is actually a great test of the monk's experience, the old man has a lot of alchemy masters' codexes here, and they have recorded what they have learned all their lives, which is very suitable for alchemists at various stages, and it is guaranteed to benefit you a lot."

After a while, Zou Lao took Yu Xiao to a library pavilion.

In the small space in front of me, the corners and sides of the wall are full of jars and jars and all kinds of sundries, and the whole ground has not been taken care of for a long time, not to mention a lot of dust, and there are some insects crawling.

In the southeast corner of the room, there are three somewhat moldy bookshelves.

The first two shelves are lined with broken bamboo slips and yellowed paper books, while the last shelf contains jade slips and two ancient scrolls of unknown material.

With such a scene, Yu Xiao couldn't help frowning, and his heart was devastated, if he hadn't seen it with his own eyes, he even thought that he had come to the wrong place.

This is completely a room stacked with miscellaneous items, what a library pavilion, the ghost will believe it.

He felt that Zou Lao must have regarded him as the kind of novice alchemy who didn't know anything, so he was ready to find something useless to take the opportunity to blackmail him with a spirit stone.

If the other party thinks so, then it is completely fooling Yu Xiao.

Besides, Yu Xiao is just pretending to be stupid, he is not really stupid, if there is really anything good here, then he can pick up Tsukidan on the road when he goes out.

He hesitated for only a moment, said nothing, and turned to leave.

At this time, Zou Lao hurriedly stopped him, and explained without blushing and heartbeat: "Ahem, don't panic, Xiaoyou, although it looks a little shabby here, it's actually okay, except for those sundries, the rest of the things are guaranteed to be treasures."

To tell you the truth, this is the secret pavilion of the Wufang Building, and the things on those bookshelves are definitely related to alchemy, the old man does not lie, since Xiaoyou is here, why not take a look at it first? ”

"Anyway, I can stay in the Great Wilderness City for a day, but I'm not in a hurry to go back."

Thinking like this, Yu Xiao still approached the bookshelf, picked up a book on it and flipped through it.

When he saw the contents inside, he was stunned.

"Jinghe Dan, a quenching pill during the Qi refining period, has the effect of strengthening the body and bones, refining formula, Huanglong grass...... Well? Why is it gone? ”

Yu Xiao was dumbfounded, the recipe for an elixir was indeed recorded in this book, but ...... It's mutilated, except for the first page, which is relatively complete, the rest of the parts are either torn off or shattered into slag, and nothing can be seen at all, isn't this a pit man.

"Old Zou, how is this book incomplete?" He asked, a little dissatisfied.

However, Zou Lao had a straightforward expression and explained: "These books have been handed down a long time ago, and some of them are naturally missing after a long time, but they are all genuine Dan books, and experienced alchemists can infer the complete content based on the missing parts.

However, it is not all mutilated, and there are many complete existences, of course, if you are troublesome, go to the jade slip on the last bookshelf to find it, where all the records are complete Danfang. ”

As soon as these words came out, Yu Xiao couldn't find any reason to refute for a while, that's right, the crippled Dan Fang is also a Dan Fang, which must be admitted.

Just as he was about to pick up another bamboo slip, Zou Lao said unhurriedly: "I forgot to tell you that the collection of books here needs two spirit stones for every time you browse an incense stick, and the rubbing cost is calculated separately." ”

"It's so dark!"

Yu Xiao gritted his teeth and cursed in his heart, but he didn't leave, but took out two spirit stones and threw them over.

It does seem to be buried here, but it is undeniable that Zou Lao is not lying, these books and bamboo slips are all related to alchemy, but most of the content is incomplete or has no practical meaning.

There may be little real value, or it may be difficult to find out.

He wasn't in a hurry, anyway, he had a stick of incense, maybe he could find something valuable in these humble books and bamboo slips.

As soon as time turned, a stick of incense passed.

Yu Xiao was still holding a roll of bamboo slips and browsing carefully at the moment, the contents of it were incomplete, but the recorded pills all made him smack his tongue in amazement, and he couldn't help but feel pity in his heart, if these contents were complete, they would be worth a lot.

"Hey, the time for a stick of incense has come, have you picked it, if not, hehe......" Zou Lao didn't say it explicitly, just rubbed his hands, and the meaning was very clear.

"Damn, this old guy mixed so many broken contents into it, if he looked for them one by one, he didn't know it would be the Year of the Monkey." Yu Xiao muttered in his heart, and simply gave up the idea of rummaging through the garbage to find the baby, and decided to go straight to his goal, the Zhuji Dandanfang.

Then, he took out two spirit stones from the storage bag and threw them over very reluctantly, while Zou Lao had a greedy expression on his face and completely enjoyed it.

This time, Yu Xiao walked directly to the last bookshelf and began to pick up the jade slip to probe into his divine sense and check the contents inside.

His movements were so fast that some of them even looked at them and put them down, looking completely uninterested.

In less than half a pillar of incense, he looked through all the jade slips on the last bookshelf, and found nothing.

At this point, Yu Xiao couldn't help but be a little disappointed, he spent time and not to mention the spirit stone, and in the end he didn't get anything useful, and he was extremely depressed.

At this moment, he suddenly set his eyes on the two strange scrolls.

According to Zou Lao, if the complete content is recorded in the jade slips, then most of these two scrolls are useless garbage.

The spirit stones that were spent couldn't be recovered, and the time for a stick of incense hadn't come yet, Yu Xiao was a little unwilling, so he simply took advantage of the last bit of time to pick up one of the scrolls and read it.

After a cursory glance, he found that the contents recorded in this scroll were very mixed, and there were five kinds of pills, and the distinction between them was not very clear.

And these pills are very strange, the spiritual herbs required for refining are more and more strange than the other, which makes people feel unbelievable when they look at it, and even the annotations of the pharmacological effects are incomprehensible, as if they are reading a book from heaven.

Yu Xiao studied for a long time, and he could only roughly see that the Danfang was complete, and as for the other things, he was confused, and it was difficult to judge their value.
