After Sun Shi explained the characteristics of all the attribute exercises, he didn't hesitate and directly chose the "Pure Heart Technique", the fastest cultivation method. After all, his spiritual root is not very good, if he chooses a simpler one, maybe his cultivation speed will be faster, and the water system exercise, although it is the weakest one among the five systems, its cultivation speed is the fastest one.

The other children are different, their talents are better than Sun Yunhao, and they naturally choose the powerful fire-based exercise "Agni Jue", and those who do not have a fire-based spiritual root either choose powerful or choose a defensive exercise.

After choosing the exercises, there were mortals of the Sun family who took out a brush and a piece of paper from their bosoms and handed them to these monks.

Then Sun Shi made a seal with both hands, and lightly touched his fingers on the five books, only to see that the five books suddenly emitted a colorful glow, and five light clusters with a diameter of about one meter wrapped the five books, and then one by one the light characters quickly flew out of the light cluster and floated above the light cluster. This colorful brilliance even attracts the attention of children more than the previous fireball.

"This is the mantra of the first five layers. Old man Sun's voice was not high, but it fell on the ears of a group of children, as if it was a wake-up call, one by one shivering, holding a brush and recording quickly.

Sun Yunhao copied quickly, and didn't think much about it, anyway, it will be a long time coming. After transcribing the first five layers of "Pure Heart Formula", Sun Yunhao felt that he still had plenty of time, so he simply copied "Longevity Formula" as well.

In less than a stick of incense, the children copied all of them, and Old Man Sun put away the five books, leaving a sentence of "practice hard, practice to the first level and come to me again", and walked away.

Sun Yunhao originally thought that this was a very Sun Dan exercise, but now it seems that it is a little different.

He saw the exercises of the first layer clearly, and then slowly inhaled the surrounding spiritual energy into his body according to the method mentioned in the exercises, and then operated according to a certain law, and finally formed a small cycle in the dantian. The result was very Sun Dan, but the aura he could collect every time was so insignificant, compared to those children who had just begun to cultivate, Sun Zhi was a world of difference.

Although he only had four hours of sleep every day, and the rest of the time he was constantly absorbing the aura of heaven and earth, and the use of the aura of heaven and earth became more and more handy, shortening day by day, but it still took nearly a year to finally bring all the aura of heaven and earth in the dantian together, breaking through some key acupoints in the body, and making it smoothly advance to the second level of qi refining.

You know, five or six-year-old children, at most, two or three months can reach the first level.

He cultivated so hard, and he was not as good as a five or six-year-old child, which made Sun Yunhao feel helpless for his inferior spiritual root.

As soon as Sun Yunhao arrived at the first floor of Qi refining, he went straight to the "Library Pavilion".

After confirming that Sun Yunhao was at the first level of Qi refining, Sun Shi handed a black bottle to Sun Yunhao, and then said with a disdainful expression.

"This is a great tonic for a low-level monk, give you this kind of garbage of the five spirit roots, Sun Zhi is a tyrannical thing!"

Sun Shi muttered to himself in his heart, but he didn't say anything annoying, but memorized the medicinal effects of practicing qi dispersion and the method of taking it, and left.

After taking the pill and returning to his room, Sun Yunhao pulled out the cork and flipped the vial into the palm of his hand, which was crystal clear, blue-yellow, about half an inch in size, exuding a refreshing medicinal fragrance, Sun Yunhao just sniffed it, and felt refreshed.

"Is this the legendary Qi Practice? Good stuff. I don't know what the effect will be if I eat it. ”

Sun Yunhao immediately sat cross-legged, took three deep breaths, and calmed himself down before swallowing Lian Qi in one gulp. It didn't take long for Sun Yunhao to feel a surging aura gushing out of his lower abdomen, he knew that this was the effect of practicing qi dispersion, so according to the method Sun Shi said, this surging aura swam around in his lower abdomen, and swam nine hundred and eighty-one circles, and this surging aura returned to Sun Yunhao's dantian.

"Just taking a pill has made my cultivation a little better!" Sun Yunhao said in surprise.

"If I could eat one every day, I wouldn't need a year, I would only need a month!" Sun Yunhao muttered to himself: "If there are enough heavenly and earthly treasures, in half a year, I can break through to the third layer of the Qi Refining Period!" ”

But Sun Yunhao had also heard that in the world of cultivating immortals, elixirs and elixirs were extremely precious things, and they could not be obtained anytime and anywhere. The Nanhua Sun family will only give it to a low-level monk once every six months.

If there are more than three layers of Qi refining, then every two months, there will be one grain, and if there are more than four layers of Qi refining, there will be one grain per month. Above the fifth layer, the effect of practicing qi dispersion will be greatly reduced, and at this time, immortal cultivators will begin to look for some more rare and effective mid- and high-level elixirs.

You must know that if a monk wants to quickly improve his cultivation, in addition to relying on excellent spiritual roots, there are two most important methods.

The first is to find a good spiritual vein. The spiritual vein is a special kind of place with rich aura.

In this world, the distribution of aura is not even, some are rich, and some are thin. Generally speaking, a place with a lot of people is a place where the spiritual energy is thin, just like a mortal city, which is why not many monks are willing to enter the mortal world, because it means that it is difficult for their cultivation to make any further progress.

Under normal circumstances, the more dangerous the place, the richer the aura, and the large and small spiritual veins will be formed. According to the intensity of the aura contained in the spiritual vein, it can be divided into three types, one is the lower grade, one is the middle grade, and the other is the upper grade. Thinking about it, those top-grade spiritual veins with extremely rich spiritual energy have been occupied by the major immortal cultivation sects. As for those low-grade spiritual veins, they were divided up by a few small and medium-sized sects.

The Nanhua Mountain Valley, where Nanhua Sun's house is located, is a low-level spiritual vein, and the spiritual energy here is much richer than that of the mortal world.

Because cultivating in this spiritual vein, the purity and quality of the spiritual energy absorbed are naturally much higher than in other places, so these monks will generally hide in some hidden place and will not go out easily.

The second way is to take things like Qi Cultivation and Cultivation.

These elixirs and elixirs are all made from a lot of rare medicinal materials and spirit trees that are old for a long time, and can only be refined through a tedious refining process. Not only are the materials extremely rare, but the success rate is also extremely low.
