Seeing that Taishang Laojun finally appeared, Li Yunfei did not continue to hide his clumsiness, and showed his things well, so as to get greater benefits in the later exchange.

These days, I stay up all night with the dragon girl, of course, not only to study the formation enchantment and talk about love, but also to join forces with the sister to create two very good Mithril treasures in my spare time.

One is of course given to the dragon girl, it is an extremely exquisite bracelet jewelry, although it only adds an auxiliary small formation, a dust avoidance force field array and a glow array, although it is useless, it looks like it makes the bracelet more and more exquisite, it is definitely a good baby to please the girl, at least the dragon girl was excited for most of the night after getting this gift.

There is also a small flying knife left by Li Yunfei himself, borrowing some functions of the Ruyi bag, adding several formations to the flying knife, which can be controlled by the divine sense, and within the range of the divine sense, it can directly have the divine sense to control the attack on the enemy.

Reciting a spell silently in his heart, the Mithril flying knife suddenly flew out of the wishful bag, and under the control of the divine sense, it instantly rushed towards Li Yunfei, the silver light flashed, and the rope tied to the body was also broken, and after cutting the rope, the flying knife turned in the air and rushed towards the Bajie Sand Monk, and in an instant, it cut the rope on the two of them.

This sudden change made several people present stunned, even the Bajie Sha Seng was no exception, and it was the first time they had seen Li Yunfei use this thing.

“…… The thing forged by the silver is really extraordinary, and it can easily break the rope made of heavenly silk! Taishang Laojun saw the material of the flying knife at a glance, and sighed very emotionally.

"Let Lao Jun see it, but there are a few little monks' self-created magic circle on this knife, and it can be regarded as sharp when cutting a rope." Li Yunfei said quite modestly.

"The holy monk is too modest, not only sharp, I see that this flying knife also has a heroic righteousness, which can break a lot of dirt and obscurity on the rope, and the holy monk is indeed a good means."

"Lao Jun praised it falsely, compared to the righteous and awe-inspiring Tiangang knife forged by Lao Jun, it is not worth mentioning, Lao Jun, please sit down!" Like a master, Li Yunfei took out a set of tea-making utensils from the Ruyi bag, boiled the tea, and prepared to entertain this veteran who had come down from thirty-three days.

In other words, Li Yunfei didn't want to be an ascetic at all, there was no way to be hungry in the past, but since he had a Ruyi bag, he had replenished a large number of living materials in Baoxiang China, and he really didn't want to be disadvantaged by eating and wearing or something.

"Holy Monk, please!" Seeing that Li Yunfei invited himself to drink tea, Taishang Laojun did not refuse.

What he was thinking about was how to exchange things with this scripture learner, but he was bound to obtain the refining method of the creation silver, the small flying knife just now had already demonstrated the excellent attributes of the creation silver, maybe it was one less rule than those innate spiritual materials that could not be found, but it was a thing that could be mass-produced, which was too important for Lao Jun, who liked refining weapons.

"Tong'er, go and call your two junior brothers, so as not to really hurt the monkey's head." Suddenly felt a few stolen nether treasures moved, it should be the two little guys and the monkey head opposite, afraid that their little boy would suffer, and hurriedly gave an order to the golden horn king who had returned to normal next to him.

"It's Master!" The king of the golden horn hastened to take the order and went to stop it.

"Well, Wuneng Wujing, you should also go to find Wukong, his temper is big, and his shot is not serious, but don't really hurt Laojun's two fairy children." Li Yunfei also gave an order to the Bajie sand monk.

Of course, the two apprentices also left, and in the blink of an eye, only Li Yunfei and Taishang Laojun were left in this huge lotus cave, and as for some other little monsters, they ran out as early as when Laojun appeared.

……

“…… What does the holy monk want to exchange for from Lao Dao? After taking a sip of the slightly bitter tea, Taishang Laojun couldn't wait to ask.

"Well, it depends on what Lao Jun wants to exchange for the little monk, if it's just a simple method of creating silver refining, as long as Lao Jun uses some refining techniques to exchange it, he won't suffer a loss if he wants to come as Lao Jun. If you want the little monk to master the knowledge of the formation that is different from Lao Jun, Lao Jun has to exchange it for the formula of the Nine Turns Golden Pill, I don't know what Lao Jun wants? ”

“…… The holy monk may not know that the method of refining the weapon of the old way is not something that ordinary people can master, otherwise my children who are not successful in the instrument will not have learned for thousands of years and have not grown. ”

"Lao Jun is too worried, the little monk doesn't expect to master Lao Jun's ingenious refining alchemy skills, but just wants to learn from the knowledge that Lao Jun imparted, and by the way, increase the little monk's knowledge."

"This, as long as the holy monk agrees to Lao Dao's condition, it doesn't hurt to pass on your refining methods and pill recipes."

"What are the conditions?"

“…… That is, you must not pass on that knowledge to others without permission, especially the Nine Turns Golden Pill must not be passed on to others. "The Nine Turns Golden Pill is a good thing that Heavenly Court uses to buy all kinds of immortal gods, and if it is spread out, it will be extremely unfavorable to Heavenly Court.

"I think Lao Jun also knows that the little monk is just a hurried passerby in this world, and after the little monk completes this great cause of learning the scriptures, the little monk will leave...... The little monk can guarantee that in this world, it will never be spread outside! Li Yunfei didn't know what the situation would be in the future, and from some fragments of dreams, he found that he seemed to have many disciples, and he didn't know whether the dream was true or false, so he didn't dare to say that he wouldn't teach his disciples after he went back!

“…… In this way, you and I will exchange! Taishang Laojun hesitated, but still agreed, in fact, as long as the formula of the Nine Turns Golden Pill was actually really leaked, it would be difficult for others to find those precious materials, and only a legal institution like Heavenly Court that controlled the Three Realms would have the opportunity to find all those precious materials.

As for refining, this kind of thing requires excellent talent, and people who are not gifted can't learn no matter how they teach, and those who are gifted don't even need to be taught to learn refining techniques from the treasures they obtain.

……

Since the conditions have been negotiated, Taishang Laojun is also simply, the person floated up directly, unfolded his divine sense, and many techniques about refining weapons, and even the perception of refining tools were all shown to Li Yunfei, as for Li Yunfei can master the helmsman, it doesn't matter to him.

Li Yunfei also expanded his divine sense perception, to carefully experience the knowledge of refining weapons and alchemy, and memorize as much as possible, even if he can't comprehend it now, he forcibly recorded it, and kept it for later to comprehend it slowly.

The efficiency of imparting knowledge through divine consciousness is extremely high, it is like copying and pasting, and it is completed in a blink of an eye, of course, it takes a long time to understand these comprehensions, Li Yunfei has not yet mastered the efficient means of direct transmission of knowledge by divine consciousness, but usually he has a habit of recording knowledge, and even makes a few more backups, some are recorded on bamboo slips, some are recorded in a notebook, and even recorded on a piece of jade.

"Laojun, this is all the knowledge that the little monk has mastered, please take it!" Li Yunfei took out several bamboo slips and handed them out.

Although Lao Jun was a little surprised to see Li Yunfei actually use bamboo slips to record, it didn't matter, as long as the content was true, with his status, of course, he was not afraid that Li Yunfei would deceive him, so he didn't even look at it and accepted the bamboo slips.

“…… Since you and I are clear, the old way will leave first! "Now that the thing has been exchanged, of course I should go back early and try to refine the creation of Mithril.

"Lao Jun has gone all the way, I will not be far away!" Seeing that Lao Jun was leaving, Li Yunfei hurriedly got up and sent it off, as long as these bigwigs give enough face, many times there will be unexpected benefits, anyway, it doesn't cost money to give face to others, so as long as they can give face, they will give it.

"The holy monk is polite, I'll go!" Lao Jun returned the salute slightly, and the person disappeared.

After Lao Jun flew away, after a while, several apprentices also hurried over, and all the belongings in this lotus cave also became Li Yunfei's bag, and it seemed that he had made a small fortune.

The things I got this time were not gold and silver treasures, but all kinds of materials, the two brothers of the Golden Horn King and the Silver Horn King, had been secretly in the lower realm for several years, and they had been trying to refine the Immortal Pill here for some days, and almost all the genius treasures within a few hundred miles of the vicinity were looted by them into this lotus cave, but in the end, they were all cheaper Li Yunfei.
