Ou Haoyun looked at several other books. "Detailed Explanation of the Five Elements Spells" records the five elements of spells and the use of the five elements spells, which is very concise and clear, just suitable for Ou Haoyun.

The things recorded in it are: fireball, water ball, wind blade and other simple spells. There are also some more advanced spells such as tornadoes, meteor fire clouds, meteorite skyfall, etc.

The things explained in "The Initial Solution of the Dan Dao" and "The Initial Solution of the Array Dao" seem to be relatively incisive, but it is a pity that Ou Haoyun has just come into contact with these things and has not conducted in-depth research on these things.

"Old Dao, these things are good, I want them." Ou Haoyun was also generous, and casually threw 5 immortal stones to Lao Dao, and snatched the five books in Lao Dao's hand.

"Uncle, look at the things on my stall, if you want it, only 50 immortal stones." Seeing Ou Haoyun so cool, Lao Dao suddenly smiled.

Now that he has ascended to the immortal realm, he is also a rich man. You must know that the immortal stones used in the plane trading center are the best immortal stones, even in the immortal world, they are precious things, and I didn't expect that the garbage in my eyes could be sold for 5 immortal stones.

"Okay, wrap it all up for me!" Ou Haoyun waved his hand and threw out fifty immortal stones, looking like a local tyrant, and the old Taoist who only looked at it jumped wildly.

Lao Dao took away the 50 immortal stones given by Ou Haoyun, wrapped the things on the stall, handed them to Ou Haoyun and said a lot, and the whole person disappeared in place.

"What's going on, how did this old way run." Seeing the place where Lao Dao disappeared, Ou Haoyun was stunned, but then he didn't think much about it when he thought that he didn't suffer any losses.

But then the words of a stall owner next to him made Ou Haoyun suddenly have an urge to vomit blood.

"Young man, you were deceived just now, that old Taoist has so many things that are worth at most one immortal stone."

"Why?"

Then the stall owner began to explain to Ou Haoyun.

Originally, in the plane trading center, there were five types of trading currencies. The lowest level is the spirit stone, and then there are the immortal stones, the divine stones, and the holy stones. and very special plane coins.

In the official exchange center of the plane trading center, in addition to plane currency, low-level currencies cannot be exchanged for high-level currencies, and the ratio of high-level currencies to low-level currencies is 1:1.

After a walk around the plane trading center again, especially after learning about the market situation, Ou Haoyun returned. However, although he lost more than fifty immortal stones this time, which made Ou Haoyun depressed, he soon stopped paying attention to it, after all, these immortal stones were not his own after all, and he didn't feel distressed if he spent them.

The day's work time ended quickly, and Ou Haoyun was in his room at night, looking at the "Mixed Yuan Jue" in his hand.

"There is a mixture of things, it is made for nature...... The essence of heaven and earth is turned into elixir......"

In the following days, Ou Haoyun has been cultivating the "Mixed Yuan Jue", but unfortunately, Ou Haoyun has not made any progress so far. He felt that this might be related to the end of the Dharma era, after all, the current society was seriously polluted, and the essence of heaven and earth collapsed, making it difficult for the human body to absorb it, which was the reason why Ou Haoyun did not make progress.

But fortunately, Ou Haoyun has "The Beginning of the Dan Dao", although the "The First Solution of the Dan Dao" tells how to make alchemy, but it also records some decoctions that can help people who have not yet entered the cultivation to cultivate.

"Ten Perfection Tonic Soup: It can speed up the cultivation speed and replenish the essence of the human body. Formula: Ginseng, Polygonatum polygonatum (Polygonatum polygonatum vulgaris), Angelica dahurica, Grass Ridge Seed ......"

"Fortunately, only ginseng is a more precious medicinal material in this Ten Perfection Tonic Soup, and the others are some ordinary medicinal materials, otherwise I can't afford this thing."

A pair of perfect tonic soup was purchased, and it cost Ou Haoyun more than 1,000. The main thing is that ginseng is more expensive, which cost Ou Haoyun more than 700.

As Ou Haoyun took the Ten Perfection Tonic Soup, Ou Haoyun only felt a blazing heat constantly colliding in his body, and then integrated into his cytoplasm. Seeing this, Ou Haoyun hurriedly ran the "Mixed Yuan Decision", and as Ou Haoyun continued to run the "Mixed Yuan Jue", the blazing heat turned into a stream of air, running in Ou Haoyun's meridians, and finally rushed into the Purple Mansion Dantian.

I don't know how long it took, Ou Haoyun finally absorbed the medicinal power of the Ten Perfection Tonic Soup, and at this time, he only felt that in the Purple Mansion Dantian, a stream of air was constantly circulating.

"I didn't expect that a pair of Ten Perfect Tonic Soup would have such an effect, although it did not break through to the first level of Qi training, but it also had a sense of qi, and the whole body was full of strength."

Ou Haoyun felt that his 1,000 yuan was worth it, but it was a pity that his savings could only buy two more pairs of Ten Perfect Tonic Soup.

In the next three days, Ou Haoyun worked hard to cultivate the "Mixed Yuan Jue" to consolidate the cultivation in his body, and on the fourth day, Ou Haoyun took another pair of Ten Perfect Tonic Soup. I felt that the true qi in the Purple Mansion Dantian had doubled.

On the eighth day, Ou Haoyun took the third pair of the Ten Perfection Tonic Soup, and as the operation of the "Mixed Yuan Jue" continuously refined the medicinal power of the Ten Perfect Tonic Soup, Ou Haoyun only felt that the true element in his body was constantly tumbling, and he was no longer under his control, but continued to run along the running route of the "Mixed Yuan Jue".

With a loud bang, Ou Haoyun felt that a pass in his body was opened, and the surging True Yuan poured for thousands of miles, and then flowed into Ou Haoyun's Purple Mansion.

Then the true yuan in Ou Haoyun's Purple Mansion Dantian flowed out again, and finally merged into the dantian, forming a perfect cycle.

"The first layer of Qi training"

Feeling the surging true element in his body, Ou Haoyun was overjoyed. After opening up Xiao Zhou Tian in his body, he finally stepped into the first layer of qi training.

However, Ou Haoyun did not end his cultivation, but continued to run the "Mixed Yuan Jue". With the opening of Xiao Zhoutian and stepping into the first layer of qi training, Ou Haoyun felt that there was no aura in the air, and with the operation of "Mixed Yuan Jue", a trace of aura continued to pour into Ou Haoyun's body.

When the operation of Xiao Zhou Tian was twelve weeks, Ou Haoyun finally stopped cultivating. There are more than ten times more true yuan in the dantian, and he is full of strength all over his body, and at this time, he feels that he can kill a cow.

"Well, why does it stink so much." Ou Haoyun, who had stopped cultivating, smelled the stench in the air, and only then did he realize that there was a layer of black dirty oil on his body, and the stench was emanating from his body.

"Cutting the scriptures and washing the marrow, I didn't expect that the cultivation of the "Mixed Yuan Jue" opened up Xiao Zhoutian, and I not only became a cultivator of the first layer of Qi cultivation, but also completed the cutting of the scriptures and the marrow, it seems that today's harvest is very big."

"Ah, Brother Yun, why did your skin become so white." Ou Haoyun, who had just washed himself white, came out of the bathroom and ran into Li Xueying.

"Yes, why didn't I find out, it was your dazzle, sister." Ou Haoyun hurriedly said. How dare he say that he became white because of his cultivation of the exercises, which led to the cutting of the scriptures and the washing of the marrow, otherwise, Li Xueying would definitely regard himself as a madman.
