In the end, Tong Meng picked up the exercise, which is called "Flame Duel", which is a kind of exercise that uses the vitality to manipulate the fire to attack.

Since he was a pseudo-spiritual root, in the past four years, he had basically not spent much time cultivating his Yuan Qi except for cultivating the "Ju Yuan Decision" he had bought every day, so he had never spent time studying the exercises of Gong Attack.

What he didn't expect was that this time he went out on a mission and inadvertently advanced to the consummation of the Qi Refining Realm, which made his heart ripple like a stone being thrown into the calm water, and he decided to divide some time on it, but fortunately, after becoming a formal disciple, he didn't have to do a lot of chores, except for tasks, he could use it to concentrate on cultivation.

Tong Meng has five kinds of spiritual roots, so he can practice exercises with that kind of attribute, but no matter which kind of exercises, the strength is much weaker than those with excellent spiritual roots.

put the things on the bed into his original storage bag, and took out the "Wu Gui Fa Yuan Decision" from "Go to Youhu".

He had advanced to the Bone Forging Mirror, and now he had to cultivate the fourth-level exercises.

Find the fourth layer of exercises, read it carefully, although it is more esoteric and difficult to understand than the previous three layers, but through the foreshadowing of the past four years, you can basically understand it.

After reading it, Tong Meng's brows furrowed.

The cultivation of the fourth to sixth layers of this "Witch Return Law Yuan Decision" requires the "Witch Law Condensing Yuan Pill", which has a lot of this pill in his "Go to Youhu", but this soaking medicine is no longer clear water, but a formation called "Gathering Stars".

In the Western Witch Classics, there is a detailed introduction to this formation and the method of arrangement, this formation is mainly to gather the light emitted by the stars in the sky in the array, and he will absorb the gathered starlight for calcining.

What makes him embarrassed is that there are a lot of materials needed to lay out this formation, and he is not good at arranging it all the way, and according to the complexity of the formation diagram, he must need a large number of hidden yuan stones, with his current six hidden yuan stones per month, not to mention cultivation, even if the resources required for this formation are enough to be saved, he doesn't know how many hundred years to be saved, not to mention that the formation is not successful with one cloth.

----------

"Reading Tianfeng" is the library of Kunwu Mountain, the reason why this name is taken is to imply that there is nothing in this library that you can't find, it is divided into the outer library and the inner library.

The outer pavilion is for those who have joined Kunwu Mountain but are not official disciples, just like in the early days, when Tong Meng did not become an official disciple, he could only consult materials here, and the materials here are all but not deeply involved, and they do not involve exercises.

The inner hall is a place for those formal disciples to use, and the materials here are more and more complete than those in the outer hall, and the depth involved is also different, and there are all kinds of exercises.

There are a lot of people in the outer hall, and there are relatively few people in the inner hall, and the person in charge is a thin old man, who looks very obscene, wearing a piece of clothing that has not been washed for a long time, and while reading a book, he also holds a small wine jug to drink there.

At this time, a little fat man with an ordinary appearance and a pair of small eyes walked over, and this person was Tong Meng.

He is not good at the formation method, although there is a method of setting up the formation in the Western Witch classics, he can't understand it, and the classics do not introduce the basic knowledge of the formation, so he came here to prepare to consult the relevant information.

"If you want to enter the inner hall, hand over ten hidden yuan stones and show the token" Seeing him approach, the thin old man was still immersed in reading.

"Ten pieces! so much, only one piece for the outer pavilion" As soon as he heard the ten Yin Yuan Stones, his heart ached, and he only had forty pieces in total.

"If you can't afford it, go away!" the old man was impatient.

Tong Meng had no choice but to put ten hidden yuan stones and identity tokens on the stage, the old man glanced at Tong Meng, picked up the token and checked it in his hand, and waved his hand without speaking, a law was played, and the door of the inner hall opened.

He didn't care about the old man's attitude, picked up the token and walked inside.

"Ten Hidden Yuan Stones can only stay for three hours, and then come and hand over ten yuan, if there is a rubbing book for ten yuan" The old man finished speaking and continued to read his book.

When Tong Meng heard that ten pieces of hidden yuan stones could only stay for three hours, it was a row, and even rubbing had to receive ten hidden yuan stones, and he thought to himself, "This inner hall is really a place to eat people."

Complaining is complaining, this is a stipulation that he has no way to change, or it is better to quickly find information.

The inner hall is tall and large, and there is a huge transparent crystal stone suspended in the sky, which shows the distribution of the inner hall and the location of various classifications.

The purpose of this trip was to find the information of the formation, thinking that he would go straight to the formation class according to the place shown on the crystal.

There are not only many books in Reading Tianfeng, but also very complete, divided into categories, and neatly placed.

Three hours passed in a blink of an eye, and when he came out of the inner hall, there were only ten hidden yuan stones left on his body.

Jia Gufeng is full of people every day, this is the place where Kunwu Mountain is sold and bought, not only there are many merchants, but also many people who swing on the beach, and they can also exchange for extra things here.

"Wanfeng Xuan" is one of Jia Gufeng's five major merchants, and the categories it operates are very complete, not only all kinds of runes, elixirs, exercises, etc., but also high-level ones such as hidden treasures are sold.

At noon, there was no one in the shop, and several shopkeepers were dozing, when a man and a woman came in, the man was twenty-five or six years old, dressed in white, tall and thin, and although he was handsome, he had a haughty expression;

The woman is seventeen or eighteen years old, wearing a purple Confucian skirt, with a graceful figure and a very good-looking appearance.

"Xiao Er, bring me the "Silver Jiao Sword" that I fancied last time," the white man shouted at the shopkeeper who was dozing off.

The second shopkeeper woke up when he heard the shout, wiped his eyes with his hands, and hurriedly greeted him with a smile.

"Hello two guest officers, please wait a moment, the kid will bring it to you immediately" The shopkeeper said as he led the two to sit down and offered two glasses of water.

After a short time, the shopkeeper walked over with a rectangular box and handed it to the man in white.

The man in white took the box and opened it, and took out a long sword from it, the sword was all silver and white, and there was a silver Jiao on the blade of the sword faintly shining with silver light, and a large piece of green jade inlaid on the hilt of the sword was a good hidden weapon.

"I don't know if the guest officer brought six thousand hidden yuan stones this time" Seeing that the man in white couldn't put it down, the guest Xiaoer knew that this time it must have been sold.

"Xiao Er, I wonder if this sword can be a little less?" asked the woman in purple next to her.

"Miss, this hidden weapon was originally going to be sold for eight thousand hidden yuan stones, if it weren't for the relationship between the master of Gong Feng and the shopkeeper, we wouldn't have been able to sell six thousand to the son, this is a high-grade hidden weapon, you can refer to the price of the hidden weapon of the same grade" The shopkeeper is a veteran, and he spread his hands with a helpless face.

"Senior sister, six thousand is six thousand, and I will definitely return it to the master when I have it" The man in white looked uncomfortable when he heard the counteroffer.

"Senior brother, that's not what I mean, it's just that six thousand is not a small number for Half Moon Peak, and the other senior brothers on the peak also need the Yin Yuan Stone," the purple-clothed girl quickly explained when she heard what the man said.
