Yu Xiu stared at the manual, his eyes were full of joy, he hesitated slightly, and did not open the manual first, but picked up the envelope that fell on the ground.

"A little friend of a break to start ......"

The envelope was unfolded, and inside was a folded piece of stationery, the handwriting on the paper was rather sloppy, apparently written at random, most likely by the four-eyebrow Taoist priest.

Yu Xiu lowered his eyes, and read the words on the letter paper in a few breaths, he held the letter paper, and his eyes were full of emotion for a while.

According to the four-eyebrow Taoist priest, the "Three Turns of the Fire Method" in the saddle is the prescription and technique of refining gunpowder, and with this method, three grades of gunpowder can be refined, and the fire talisman or fire pill can be used by the ninth, eighth, and seventh-grade Taoists to quench the Yin God.

"There is nowhere to find the iron shoes, and it takes no effort to get them. Yu Xiu sighed lightly in his heart.

However, this method was not given to Yu Xiu by the Simei Taoist priest for free, and the letter said:

"And use this technique as the capital for the purchase of goods, and buy a Xiucai scholar...... Money and goods are not owed!"

Yu Xiu stared at this sentence and smiled dumbly in his heart, "What's the difference between this and giving it to me?"

According to the Simei Taoist priest, he took the scholar as a slave without telling him, and the "Three Turns of the Fire Method" was used as money to buy the scholar.

It is said that although the scholar was brought into the ghost market by Yu Xiu, he is not his slave, and Yu Xiu will not be a human trafficker who buys and sells readers, so it naturally has nothing to do with him if the scholar stays.

Upon closer examination, the words of the four-eyed Taoist priest should be half a joke, half a thank you to him for saving the scholar once.

"That scholar is lucky, it seems that the four-eyed Taoist priest has decided to accept him as an apprentice. Yu Xiu pondered for a long time, silently folded the letter, put it in the envelope, and thought to himself: "If there is a fate to meet again, I will definitely repay the Taoist priest." ”

This technique came at a timely time, and it was related to the practice of the rest of the rest. If the four-eyebrow Taoist priest does not give this technique, most of the rest of the rest will be wasted for three months, or even half a year, and at the same time, the foundation may also be affected.

He secretly wrote down the kindness of the four-eyebrow Taoist priest, and then pinched the "Three Turns of the Fire Method" and looked at it roughly.

The number of words on the booklet is small, but thousands, but the sentences are concise, the content is detailed, there are pictures and words, and there are ink on some pages, which should have just been written.

Then read it carefully. Yu Xiu looked through it and closed the book. At this time, he had already retired from the guest room, and it was less than three hours before the end of the ghost market, so it was obviously not a good time to study the secret method.

Yu Xiu put away the manual, put the saddle on the thin horse, and walked out of the inn as usual.

When I came to the street, the pedestrians around me were much sparser again, and they had become sporadic again.

Yu Xiu led the horse away, thinking back to what he had read in the manual just now, and thought to himself: "The ghost market is not over yet, so I should hurry up and purchase it, so that it is convenient to refine gunpowder later." ”

Gunpowder was researched by Taoist priests when they were refining Dan, and if they wanted to refine gunpowder, they naturally needed Dan furnaces and other things.

If Yu Xiu was outside the ghost market, he would probably only be able to make do with ordinary things such as copper furnaces and iron furnaces, but now that he is still in the ghost market, he naturally has to buy high-grade utensils.

It is said that the division of weapons and magic weapons in the world is the same, and they are all divided into nine products and twenty-seven according to the number of meridians in the utensils.

The more meridians, the stronger the spirituality and power of the artifact, and the easier it is to be manipulated by the thoughts of Taoist priests and the blood and qi of warriors.

Among them, the utensils of the lower three grades, the number of meridians is between one and nine, and the martial arts are called "treasure soldiers", and the fairy road has no special title, only the product.

The number of meridians reaches more than nine in the three products, and the martial arts are called "secret soldiers", and the immortal road is called a magic weapon.

This grade of magic weapon is the real magic weapon in the immortal path, and its spirituality has increased greatly, and it has all kinds of miracles.

The utensils of the upper three grades, the number of meridians reaches more than eighteen, the martial arts are called "divine soldiers", and the immortal road is called "magic weapons".

Among them, there are 27 meridians, which are the same as the number of meridians in the human body, which is regarded as a "half-human", which is the existence of suppressing luck, and can be refined by Taoists as an incarnation outside the body, and resides in the Yin God.

It is even rumored that there are magic weapons to create 28 meridians, which should be with the 28 stars in the sky, and the utensils become gods by themselves, known as "artifacts" and "immortal weapons......

"I don't know what grade of artifact the jade cicada belongs to...... Yu Xiu thought suddenly, remembering that the cicada was fine and dense, like the silk threads of the meridians, and his heart tightened.

Putting aside this idea, Yu Xiu hurried to wander around the ghost market, and finally bought a copper stove in an elixir shop.

This stove is not big, only a few inches, and the inside is divided into two layers, shaped like a gourd, which is quite delicate and just convenient for Yu Xiu to carry.

According to the shopkeeper, although this furnace is small, it is suitable for burning a small amount of pills, even if it is not used for alchemy, it can also be used as an incense burner for burning incense and burning money, and it will definitely not be wasted.

Yu Xiu was noncommittal to the shopkeeper's words.

If he hadn't seen a meridian in the copper furnace, and tested it with the blood gas furnace to confirm that the copper furnace was a grade artifact, I'm afraid he would have hesitated for a long time in the ghost market.

The copper furnace costs 100,000 yuan, which is twice as expensive as the talisman pen that also has only one meridian, but this is already one of the cheapest in-grade Dan furnaces in the ghost market. Others, more expensive!

After buying the Dan furnace, Yu Xiu hurried up and bought yellow paper, ink blocks, corpse gas and other things to draw talismans from all over the ghost market.

It wasn't until the end that all the silver money on his body was replaced with materials for painting talismans and cultivating the Dao, and Yu Xiu led the thin horse and had to go outside the ghost market.

Crashing into the thick fog, Yu Xiu walked for a long time, and when he came back to his senses, Yu Xiu looked around and found that he was in a dense forest, surrounded by silence and no sound, and quite far away from the valley where the ghost city was located.

"There are really masters in the ghost market. After a little thought, he knew that this was the function of the formation, which could help the people who left the ghost city to hide their tracks.

Yu Xiu turned over and thought of his harvest in the ghost market, and his heart was quite comfortable, "Next, it is to refine gunpowder, burn the Yin God, and even break through to the realm of day travel!"

He looked at the dense forest, drank lightly, and immediately galloped on his horse.

As for the direction he was heading, Yu Xiu had already had a plan in his heart.

Refining gunpowder requires a variety of materials, especially sulfur, charcoal, and other materials, which are in great demand, and it is impossible for him to buy them all in the ghost market.

Therefore, Yu Xiu's next goal is to go to a certain mountain, collect sulfur and other materials, and refine gunpowder at the same time.
