The reason why Nie Fei's strength has increased by a hundred times is also because of his ice ball-like aura. From the Qi refining period to the foundation building period, it is a process of spiritual energy condensation, but no matter how condensed it is, ordinary people are still gaseous aura. Nie Fei's solid-state aura was originally the result of condensation, and after the foundation was built, it was condensed again, and the aura after this condensation was naturally smaller than before, but this was the result of several compressions of the aura.

This kind of compressed solid aura, the aura contained in it, is unimaginable to others. It can be said that a small piece of the solid aura, less than one-tenth, has the amount of aura when the qi refining was completed before. In addition, this aura is purer than during the qi refining period, and the aura of various attributes that it can carry is also much enhanced.

The current Nie Fei, although he has only only completed the foundation building, it is no exaggeration to say that with the ice hockey ball formed by the aura, he is already equivalent to the level of ordinary people in the middle stage of foundation building.

In addition, Nie Fei's Ice Spirit changed into a cold attribute aura, which was previously limited by cultivation and could not fully exert its power. At this time, the aura is more condensed, and the ice spirit transformation is also beginning to take shape, at this time, Nie Fei can really exert the power of the ice spirit to become seventy.

......

Then, Nie Fei spent another day conditioning to stabilize the aura after building the foundation. Then, Nie Fei slowly stood up from his meditating state, and a majestic aura rippled around him, and soon spread throughout the cave.

Bai Qingxuan, who was sitting on the cobblestone, felt another wave of spiritual energy. He opened his eyes again, trying to detect the source of the fluctuations. However, the fluctuation soon disappeared, and he was vigilant for a long time, until there was no more movement, and then he gradually closed his eyes again.

Nie Fei took a deep breath and stabilized the aura that was still rippling in the sea of qi, and it was only at this time that Nie Fei could truly become a foundation building stage monk.

Nie Fei opened his eyes and looked down at his hands, the skin of his hands, which were as crystal as jade, exuding a halo. He touched his face again, and it became smoother. And the sense of smell, sight, hearing, every sense, has become extremely acute, and it seems that everything that can be felt has been magnified countless times more than before.

"It seems that the foundation has not only improved the aura internally, but also changed a lot physically. Nie Fei thought secretly.

At this time, Nie Fei stared in the direction of the cave entrance for a while. He sensed that at the entrance of the cave, there was an unusually powerful aura fluctuation. He immediately remembered the person who chased him into the cave, the person who beat the rain without knowing anyone in one move, and the monk who was in the foundation building period.

A sneer appeared on Nie Fei's face. At this time, he already had a deeper understanding of his own strength. The person at the entrance of the cave was only in the early stage of foundation building, and although the aura was also very strong, what was that?

Nie Fei slowly raised one foot and stepped towards the entrance of the cave. Almost in the blink of an eye, the entrance to the cave was reached. Nearly 30 zhang distance, one step to reach, this is the strength of the foundation building period.

Nie Fei raised a hand and waved it lightly, and a stream of spiritual energy surged straight towards the entrance of the cave. The aura was like a puff of green smoke, gradually blending into the formation at the entrance of the cave, and the formation at the entrance of the cave was slowly lifted at a speed visible to the naked eye.

Bai Qingxuan, who was sitting on the cobblestone, suddenly felt a strange feeling coming from where he was sitting. He immediately rose into the air and turned to look at the cobblestone he was sitting on. I saw that the cobblestone, like ice in the sun, gradually melted, and in less than a moment, it was completely dissolved.

Bai Qingxuan's eyes widened, looking at the scene in front of him. At this point, he completely understood that the cobblestone, where was the real cobblestone, but a part of a formation. It's ridiculous that I've been sitting here for half a year, and I haven't even noticed it.

As the cobblestone dissipated, the opening of a black hole was revealed, and from the mouth of the cave, there was a peaceful and extremely majestic aura fluctuation. Bai Qingxuan squinted his eyes slightly, staring at the entrance of the cave.

A figure slowly appeared at the entrance of the cave. At first, he could only see the outline of a human figure, but after a while, the person broke through the light, like a golden-armored god of war who had come out of the dark hell, bathed in golden sunlight, and the whole appeared in Bai Qingxuan's eyes.

Bai Qingxuan squinted his eyes vigorously, and he realized that the aura on this person's body was very majestic, and his cultivation was at least a foundation building period. But how could there be a monk in such a cave?

The man took a few steps forward, and Bai Qingxuan finally saw clearly that the man was looking at him with a sneer on his face, his eyes flashing. As soon as he saw the person's appearance, Bai Qingxuan was suddenly stunned, "You...... ...... are you" Bai Qingxuan recognized it, this person was the kid in the Qi refining period that he hunted down, and he disappeared here, it turned out that he was hiding in this cave, thinking about it, there was a formation before that cave that prevented Bai Qingxuan's exploration, so he never noticed the trace of that kid. These, Bai Qingxuan's mind turned, and he guessed it with a guess.

What Bai Qingxuan never expected was that before this person disappeared, he was only a seventh- or eighth-level cultivator of qi refining. However, when he reappeared, how could it already be the foundation building period? Yes, it was the foundation building period, yes, the majestic aura could not deceive people. But how is this possible? Half a year, only half a year. If you cultivate quickly, you may improve by a level, from seven or eight layers to the ** layer, which is possible. But how can people believe that they have raised a level?

"Do you recognize me?" Nie Fei said word by word to Bai Qingxuan, who had an expression of disbelief on his face.

Bai Qingxuan nodded desperately, "Are you ...... How could you ......"

Nie Fei waved his hand lightly, "Okay, since you recognize me, then, take it." With that, Nie Fei raised his left hand lightly and shouted softly: "Snow falls." A gust of cold wind whistled past Nie Fei's hand and flew towards Bai Qingxuan. As the wind rose, a cloud of gray snowflakes, wrapped in the cold wind, rushed towards Bai Qingxuan together. Nie Fei's move is also a move in the "Ice and Snow Technique", although the exercise is an exercise in the Qi refining period, but the cold qi in it is extracted from the ice spirit, this is the ice spirit in the foundation building period, and the power is no longer comparable to the Qi refining period.

Bai Qingxuan hurriedly carried the Dead Earth Technique to resist. Earth Aura is the best at defense, although this Dead Earth Exercise is an attack-based exercise, but defense is the innate advantage of Earth Spirit, this Dead Earth Exercise has its own defensive attributes, and its defense power is equivalent to the defense power of other attributes of specialized defensive exercises.
