I don't know how long I meditated like this, but the slight flush on Su Yuan's face slowly faded, revealing a beautiful face that was originally expressionless. Her figure is still motionless, but her light sleeves rise and fall among the green mountains and green waters.

The breeze is blowing, the mountain stream is like a belt, and the blue waves are surging.

A large skirt fish descended from the upstream and jumped up in the middle of the stream. But before the fish could react, a dazzling silver light flew towards it at a lightning speed, and the next moment it stabbed into it steadily. The silver light flashed, and the original form appeared in the belly of the flower skirt fish that jumped into the void, and it was a small sword with an inch of silver.

The fish was struck, staggered into the stream, and then flicked its tail a few times and made a few splashes, and for a moment it lost its breath and stopped moving at the bottom of the stream.

A chuckle came low, and followed the direction of the voice, it turned out that it was Su Yuan's trick.

She let out a long breath of turbid air before slowly opening her eyes. His bright eyes flickered a few times, and after looking around, he saw that there was no movement, and Su Yuan was happy.

"Finally broke through the fourth layer of qi refining!" she murmured, the corners of her mouth curled slightly, and her chin looked at her slender and white hands.

In order to break through the fourth floor, Su Yuan had been preparing for more than two months. Now that my cultivation is one step closer, I am naturally quite satisfied with myself. The fourth layer of qi refining can fly at a low altitude with magic weapons, and this escape technique alone is far from being comparable to the third layer, and its strength has greatly increased in the fighting method.

Su Yuan pondered silently for a while, and then gradually put away his mind and focused his gaze on the bottom of the stream.

After meditating and practicing by the stream for several months, this kind of flower skirt fish has really caught a lot. Fortunately, I have never been tired of eating, and I have always been interested. She got up and straightened her dress, pinched the trick again, and used the dust removal technique, and the yellow dress that was originally a little wrinkled and dull suddenly took on a new look.

This dust-removing spell is recorded in the book of the gray-faced old man's storage bag. Su Yuan has lived in the mountains and forests for a long time all the year round, and his cultivation is not profound, so he will inevitably suffer from wind, frost and rain. Although she is not squeamish, she is also a girl after all, and naturally she also wants to be fresh and clean. The dust removal technique happened to have the characteristics of driving away dust and eliminating pollution, so I carefully studied and cultivated.

Now that the dust technique has been used by her to the extreme, Su Yuan felt that her body was refreshed, her heart was happy, and she smiled lightly. I couldn't help but spin in place a few times, and the skirt swayed like a flower blooming, and then I stopped quite satisfied.

Look at the bottom of the stream again, the flower skirt fish is lying quietly in it, Su Yuan stepped forward and pinched the trick with one hand, her body did not move, and the other palm stretched out in the void, and a thin water column slowly rose from the bottom of the stream, holding the flower skirt fish to rise into the air, and then quietly fell into Su Yuan's palm, and the water column slowly retreated into the stream.

This is another spell that Su Yuan practiced - Water Wave Technique, and Yu Dust Removal Technique came from the same book.

She was originally a water and wood spirit root, although she had cultivated other low-level spells such as the Fireball Technique and the Wind Blade Technique. But it's not fast, and it's not too powerful. Now that there are spells of the same attribute, it is naturally more convenient to use.

The small silver sword was retracted and put back into the storage bag. Su Yuan rinsed the fish with scales and distractions, stuffed a small handful of spirit grass into its abdominal cavity, and pierced it with a bamboo pointed handle. These steps seem troublesome, but for Su Yuan, they are simple and abnormal, and her movements are so skillful that she doesn't need to think about it at all as if she is instinctive.

Su Yuan rubbed his fingers, and a ball of fiery red light appeared on his fingertips out of thin air.

The effort was not great, and the fragrance of the fish slowly came, Su Yuan did not hurry to turn it over and look at it, then nodded secretly, and sprinkled seasoning powder around the fish.

Although Qi refining period cultivators do not need to sleep all day long with three meals a day like mortals. However, if you want to completely open up the valley, you must build a foundation and cultivate the above to do it. Su Yuan can go without eating or drinking for two days, but once the time passes, he will feel hungry and slack.

The smell of the grilled fish became more and more fragrant, and Su Yuan looked again to confirm that it was time for the fire. He put away the fireball, and his eyes did not leave the head of the fish's jaw and drooled.

The days of eating fish like this lasted for several days, during which Su Yuan was not idle except for cultivation, and studied the array books that he had exchanged for at Aunt Fang City.

In the world of cultivating immortals, the magic circle is divided into auxiliary type, defensive type and offensive type.

Among them, the auxiliary type includes water dividing array, spirit gathering array, sound insulation array, dust removal array, etc. It is used to assist monks in their cultivation or to play a role in specific situations.

The defensive forbidden magic circle is to use the power of the five elements in a certain area, and complement each other through the way of balance to achieve the defensive strength of the formation. Once an external force breaks the balance and violates the prohibition, it will be resisted or punished by the formation. These two types of circles are also the most widely used among monks.

Offensive circles are used for defensive purposes, and as the name suggests, they are mainly used to attack and knock back. This kind of formation is limited by geography and has a lot of anger, and if you break into it, you must follow the rules of the formation. It is generally used among monks above the foundation.

In addition to the above three, there are also powerful magic circles such as seals and psychics. This kind of circle has a lot of consumables and is very powerful. Generally, the sealing circle can only be operated in the hands of monks above the knot stage, but if it is a giant sealing circle, it can even be controlled by a Yuan Infant monk. As for the psychic array, Su Yuan's book was only mentioned in one stroke, and he didn't explain it too much.

In addition to the above circles, there are also teleportation circles that can teleport people to another location or space.

Although the above formations have different functions, they all need to consume spirit stones as power to trigger the opening.

When Su Yuanpan sat on the stone bed of the cave and looked at it intently, he remembered all these in his heart.

With what she knew now, she could only barely comprehend some defensive and auxiliary formations, after all, there were many profound things that she could not comprehend with this kind of cultivation.

Despite this, Su Yuan was already satisfied, the fat man could not eat it in a day, and if he wanted to go further in the cultivation realm, he had to accumulate little by little, and laying a good foundation was the safest way.

After looking through for a few hours, Su Yuan flipped through it with one hand and took out several array flags from the storage bag.

She waved in the void, and the small flags in her hands fell in several directions, and disappeared in the blink of an eye. Su Yuan then placed four spirit stones in the eyes of the formation in all directions. In an instant, a series of criss-crossing chaotic aura faintly appeared, shuttling between several small flags.

The Dharma in her mouth did not stop, and the aura gradually soothed under the guidance of the mantra, with Su Yuan as the center, a virtual image of the spiritual aura circulating around the cave was formed. As soon as Su Yuan's mantra stopped, the spell casting guidance had just been completed, and the image of the magic circle slowly rose from the center, faintly forming a spiritual aura light mask, and the light mask emitted a blue and faint light until it enveloped the entire cave, and the light mask gradually disappeared when it stopped.

Su Yuan got up and looked around. Confirm that the magic circle is set up, and nod lightly secretly.

There were not many spirit stones before, for fear of wasting spirit stones, Su Yuan didn't dare to practice in vain, and after several speculations in his heart, after simulating practice, he finally tried to set up the formation, and finally succeeded in one fell swoop.

It's a basic formation, but it's enough for her. With this layer of protection, when cultivating the exercise in the future, if someone breaks in and disturbs you, you can barely buy some time, so that you will not be too passive.

In this way, when he noticed that the aura by the stream was strong and strong, Su Yuan took the opportunity to quickly meditate on his luck. Sometimes a sitting cross-legged for half a day, after the aura is evacuated and gone, only then do you leave to go to the cave to rest, and then eat something to replenish your strength, or go to the nearby to collect elixir and spiritual grass.

Finally, another two months passed, and Su Yuan's cultivation advanced to the fifth level of qi refining again.
