This young man is none other than Nie Fei, who has been imprisoned for seventeen days. In the past seventeen days, Nie Fei has not stepped out of the cave for a single step, and most of the time, he has been absorbing the spiritual energy in Xie Ling's herbal liquid. Finally, on this day, he absorbed all the Xie Ling herbal liquid in more than a dozen jade bottles, and then walked out of the cave.

More than a dozen bottles of Xie Ling Herbal Liquid made his aura level jump from the first layer of the Qi Refining Period to the fourth layer of the Qi Refining Period, and only a little bit closer, he could reach the fifth layer, and the effect of these dozen bottles of Xie Ling Herbal Liquid was completely beyond Nie Fei's expectations. He really didn't expect that in less than twenty days, his aura level had actually increased so much.

However, he also felt that the higher the level of aura, the more aura was needed, which meant that the more Xie Ling herbal liquid was needed. For example, when he took the first bottle of liquid, the aura level went directly to the second layer. But after reaching the fourth layer, he took four bottles of liquid medicine in a row, and the level did not break through the fourth layer. "That's it for this time, just prepare some more liquid next time. Nie Fei thought secretly.

In the past ten days, he has only eaten very little, and until now, he has not felt any discomfort or hunger. He knew that after the Qi refining period reached the second layer, he could open the valley, although he could not achieve absolute valley cultivation, but it was enough to eat a little.

The most uncomfortable thing for him now is that he hasn't bathed for seventeen days. To tell the truth, his body was nourished by the aura every day, and he didn't produce any filth at all, so he couldn't smell a trace of odor on his body. But he hadn't taken a shower for more than ten days, and he felt uncomfortable anywhere.

Nie Fei remembered that on the way here, there was a mountain spring, not far from here, so with the help of memory, he found the mountain spring and washed it there, which made him feel better.

Although the aura of more than a dozen bottles of medicinal liquid had already been incorporated into the sea of qi, Nie Fei had no intention of going back. His aura level had been raised to four layers and close to five layers, and it was time to practice some exercises.

So far, the exercises he has learned are only one palm fire, and he plans to consolidate this palm fire practice a little more. In addition, in his storage bag, he found that there was an exercise called "Water Thousand Illusions" inside, which could only be cultivated after the fourth layer of the Qi refining period. He is now at the fourth layer, and he can completely cultivate this Water Thousand Illusions Technique.

Therefore, after he washed it clean, he immediately returned to the cave and began to cultivate the palm fire and water thousand illusions.

The palm fire exercises, he would have been, and he did not hesitate to move the exercises immediately. A cluster of flames burst into flames from the palm of his hand, and as Nie Fei couldn't stop urging the aura, the cluster of flames burned higher and higher, and the more vigorous they burned, until the entire palm of his hand burned into flames, and the flames no longer spread. Nie Fei continued to urge the aura, and although the flames no longer spread, the color changed, the color became lighter and lighter, and the brightness became brighter and brighter. Nie Fei knew that the lighter the color of the flame and the higher the temperature, he wanted to try to see how far he could control the flame.

So, he kept urging the aura, and finally forced all the aura in his body out, until this time, the color of the flame no longer changed, and it was stable in a color with a hint of blue.

This state of urging the aura with all his strength could not last, as Nie Fei slowly withdrew the aura, the color of the flame gradually deepened, and the red color became more and more obvious. "When the flame color turns white under the pressure of all your strength, it should be the time when this exercise is completed. Nie Fei thought secretly.

In order to verify how high the temperature of this flame was, Nie Fei once again urged all the aura, and the flame burned vigorously from the palm of his hand, with a slightly strange blue color, which looked extremely magnificent. Nie Fei looked around, it was either rocks or trees, so he walked quickly to a tree with the thickness of a bowl, and pressed his palm on the trunk. I could only hear a "sizzling" sound, and Nie Fei's eyes were black smoke and white fog, and when the smoke cleared, Nie Fei found that the tree in front of him had already turned into a pile of ashes, and the whole thing was scattered on the ground. In the midst of the ashes, there were faint embers, emitting a dark red light.

Nie Fei was dumbfounded. He never imagined that under the fourth-layer aura of this Qi refining period, the palm fire would be so powerful that it could turn a big tree into ashes in an instant. He smacked his tongue, this is only the introductory stage of immortal cultivation, if those immortal cultivators who are in the Dan stage of building the foundation use this palm fire and go down with one palm, won't they set the entire forest on fire?

He couldn't have thought the right thing about this. Palm Fire is just a low-level exercise, and it can also be regarded as an introductory exercise for immortal cultivators, with the improvement of the realm, it has its own more powerful exercises, who would still use such a low-level thing as palm fire? Unless those people are bored, or want to relive the scene of entering the Immortal Dao for the first time, they will never use this low-level exercise.

Nie Fei saw that the power of the palm fire was so shocking, he didn't dare to use trees to test it again, if he was not careful, he wouldn't make another forest fire. He turned and focused his gaze on the stone wall in front of him. With a burst of "hehe" laughter, he slapped one palm after another at the stone wall. The stone wall couldn't withstand the high temperature of the palm fire, and it melted and softened, so that Nie Fei could shoot a palm print as deep as two inches with every palm.

Nie Fei was very interested, and he took a total of half an hour before he slowly put away his aura, and the fire in his palm was extinguished. He raised his eyes to look at the stone wall, and saw that there were about 100 palm prints on the stone wall, which were arranged in order and connected into a traditional Chinese character "飛". Looking at the majestic flying word, Nie Fei couldn't help but smile and was very satisfied with his masterpiece.

......

In the next few days, Nie Fei never came out of the cave, hiding in the cave to learn and practice the Water Thousand Illusion Technique.

As soon as he came into contact with this exercise, he deeply liked it. Just because this exercise is the ever-changing characteristics of water vapor, it can be transformed into all kinds of things, and it can be transformed as long as you can imagine it, which can really be described as ever-changing. Of course, in order to make the illusion of something vivid and look the same as the real thing, it is necessary not only to practice this technique diligently, but also to fully understand the thing, which varies from person to person.

Nie Fei didn't expect that in the practice of cultivating immortals, there was such an interesting thing, which did not have a trace of domineering, but was very artistic. "Right...... Artistry. Nie Fei nodded, thinking that these three words could very well reflect the characteristics of this exercise. The only fly in the ointment is that the things conjured up by this exercise are just monotonous water vapor white, thick or light, even if the conjured things are similar to the original things, people can see the authenticity at a glance.

This is his understanding of this exercise, if it is known by the predecessors who first created this exercise, he will definitely be angry to death. What kind of artistry, Lao Tzu will come up with those boring things? The original intention of the predecessors to create the water thousand illusion technique was purely to use it as an illusion to confuse the opponent. But if you think that this is just a simple illusion, but you also look at the water thousand illusions as simple, the wonder of this exercise is that it is imaginary and real, and it is difficult to fathom. When this exercise transforms things, as long as the realm is profound, and the aura is continuously injected into the illusion, the virtual can be turned into reality, which is difficult to prevent. For example, if you use this water to conjure up a sharp blade, you think it is an illusion and ignore the sharp blade that stabs you. How do you know that the blade can turn the virtual into reality, and it can pierce your chest in one click. Therefore, when fighting against people who use this exercise, no one dares to be careless, in case the other party comes to turn the virtual into reality, it is not a joke. Therefore, when this technique is facing the enemy, it is very able to distract the opponent's energy.

After a few days, Nie Fei's love for this exercise far exceeded that of the palm fire exercise. He hid in the cave and happily conjured up something he could imagine. First conjure up a "two yellow orioles singing green willows", and then conjure up a "line of egrets in the sky". What God, Jesus, Buddha, he conjured one after another, he didn't know if there was any charm, it was estimated that there was no charm, because these great gods all had his face.

One day, he felt that there was really nothing to distort, and suddenly a flash of inspiration flashed in his mind, as if he had been struck by lightning. He gradually put away the smile on his face, his expression became solemn, and he was silent for a while, and then he sighed, containing infinite sadness. He slowly stood up, waved his palms together, and two mist flew out of his palms and gathered in front of him. Nie Fei closed his eyes, he couldn't bear to look at it, but the movement of his hands did not stop, and the fog became thicker and thicker, converging into a ball. Gradually, the fog began to change, and it took on a head and face. This time, Nie Fei conjured two humanoids.

After a long time, Nie Fei opened his eyes, and at this time, his eyes were full of tears. "Dad, Mommy......" He trembled his lips and called out these two words, and finally he couldn't stop crying and fell to the ground.

The two people who were conjured up by the mist seemed to be unable to bear to see him like this, and the faces of the two mist were full of love. Nie Fei looked at the two phantoms in front of him obsessively, and he didn't know how long it took, when suddenly he stood up with a bang, wiped away his tears, and waved his arms one after another. The two clouds of mist dispersed, and in a matter of moments, they disappeared without a trace.
