The light and shadow spirit floated in the air three feet high, silently motionless. Xu Fei was a little dumbfounded at this moment, but his body did not stop, and immediately pointed his toes on the ground, making a "crane soaring to the sky" rise from the ground three feet high, and directly take the light and shadow.

And this time, the light and shadow elves didn't have any fancy, but just flew upwards again. And Xu Fei's strength for this leap has reached the limit, and he can't help but fall. The light and shadow spirit stopped in place and did not move, but it was more than a foot taller.

With Xu Fei's martial arts, even if he doesn't have the strength, he can jump on the wall more than two zhang high, and now he has the blessing of strength, and the height of four zhang is not in his eyes, and he immediately rises from the ground and rushes straight to the target. Unexpectedly, the light and shadow elf flew upwards for more than a foot almost at the same time, almost reaching the top of the tower.

The height of the fourth floor is a superposition of two layers of tall towers, and the space of the spire adds up to nearly ten zhang high. And even if Xu Fei pushed his strength to the extreme, he could only reach a height of about five zhang. In the face of the light and shadow elves, they are really helpless to improve higher and higher each time.

If you fly and jump like this again, as long as this light and shadow continues to rise, you can make yourself helpless, and you must understand the purpose of Dugu's predecessor to set up such a mechanism. Only in this way can you find the direction to improve your abilities.

Since the two tests were solved by improving the "condensation qi", this time it must be solved with this kind of energy. Can he raise his body again by bursting into air bombs in mid-air? Xu Fei has no other way to retreat, but to try hard!

I saw Xu Fei's body squatting deeply, the muscles of his thighs bulging, and they became hard like iron and stone. I only heard a loud roar, and my body rushed into the air like a cannonstone, and this leap was more than five feet high.

And the light and shadow elves really flew to the top of the tower again, and Xu Fei's strength of this leap reached the end of the strong crossbow, but he violently erupted at his feet. The body seemed to have gained a huge momentum, and it flew upwards again, and before the body could descend, it burst out again with an air bomb counterattack.

Xu Fei's body was like an accelerating cannon that shot upward, even the top of the tower could reach it with this method. It's just that in the process, because of the frequent urging of energy, the breath began to be insufficient, Xu Fei's breath changed his breath, but he felt that his body fell from the air as soon as he sank.

The light and shadow elves were so far out of reach in the sunlight at the top of the tower. Because it was too high off the ground, Xu Fei hurriedly reversed the momentum when his body fell, so as to stabilize the sharp falling momentum of his body.

Just now, he continuously urged his energy to attack upward, and he was about to succeed, but his body fell because he breathed in the air. With this, Xu Fei understood the characteristics of "condensing qi" to urge the body, that is, in one breath, the user can go back and forth freely in the air.

But as long as this breath is not enough, it will lose this advantage of being able to change direction freely in the air. If it weren't for Dugu's defeat predecessors using this kind of light and shadow elf mechanism to induce, just relying on his own little bit of exploration, I don't know what chance it would be to find out.

If it is when you are fighting against the master that your breath is sluggish and your body is uncontrollable, I am afraid that it will be more than lucky. It seems that each of the organs of Dugu's predecessors has its deep meaning.

As long as he understands the joints, the height of ten zhang is still difficult for Xu Fei, and when he was about to take a deep breath and jump up again, the group of light and shadow elves seemed to understand that this kind of height was difficult for Xu Fei, and he had already lowered the height and suspended at a height of about two zhang.

But despite the reduced altitude, the trajectory of the flight is complex and unpredictable, as if provoking an opponent. If you jump up and can't hit it, it will fall, and you can see from the movement of this light and shadow in the air that it is difficult to hit it with one hit.

The so-called drum does not need a heavy hammer, but Xu Fei saw the main point of this.

Dugu's predecessors are really well-intentioned, and the test on the third floor is used to test the basic application of "condensation". Then do a flat chase, so that he can realize the impact of condensation on his body when facing strong enemies.

Finally, through the space of this ten-zhang tall tower, he realized the limitations of the "condensation" method. Remove the hidden dangers that may be exposed in the future. Now that this light and shadow elf is doing such a flight trajectory in the sky, it is natural to let himself capture it in this space.

And using "condensation" in the air to change the position of the body can only be breathed in one breath, and there must be no exchange of breath in the breath, otherwise the body will immediately stagnate and fall. Therefore, capturing the light and shadow spirits in the air tests the length of the breath and the control of changing directions in the air.

After thinking about all this thoroughly, Xu Fei took a deep breath, and all the limbs of his body relaxed, and he no longer used other strength as an aid. In this way, the energy condensed is not hindered in the body.

The body seemed to be light and nothing, only the toes touched the ground slightly, as if it was about to fly in the sky. Suddenly, Xu Fei's body flew up sharply, and he took the little light and shadow elf.

The light and shadow elf immediately changed its direction in the air, flying in this huge space, only to see a figure like a sword fairy chasing that small light and shadow in this empty space, in this void, one after the other unpredictable.

With the sound of air bombs, Xu Fei volleyed in the air, and in this space, it was like a swimming fish swimming as he pleased. After a while, Xu Fei's breath had reached its limit, and as soon as he breathed a little, his body sank extremely quickly and landed on the floor.

Although it is only a short chase, this kind of volley of urging "condensation" is extremely expensive. Xu Fei is not in a hurry now, because he knows that these are all necessary steps, and this is the path that Dugu's predecessors gave him.

The two people, who have spanned hundreds of years, are like a pair of master and apprentice, and there is a collision of hearts.

Again and again deep breaths, again and again in the air, again and again in the air, again and again and again failed. Xu Fei's sweat had soaked through his clothes, and his breath began to gradually become faster.

But even if his aura was not as abundant as when he first stepped on the fourth floor, he was getting closer and closer to the light and shadow spirits, and he was becoming more and more proficient in using "condensation" to turn the direction in the air.

Where is the air hole bursting out, how powerful is the air bomb countershock, how can the surrounding air flow be used for one's own use, how can the body be turned into an almost nothingness state, so that the energy can be more smoothly urged. Little by little, these problems are being overcome and solved.

Xu Fei's body turned in the air, as if the sky was his home, as if he had become a child of the wind. The change of light and shadow in the air was not arbitrary, but also moved according to the principle of the control method of the top master of "Qi Condensation".

With this discovery, the confusing target has become a rule-based one, and even the changing path of light and shadow can be predicted in advance. The distance between myself and the goal is getting closer and closer, and the chase after each cross-knee meditation is one step closer to success.

This light and shadow is like the figure of Dugu's predecessors, guiding himself on how to use the changes in his body method, and the flight trajectory that every light and shadow elf can make can be done by relying on the "condensation" method. That light and shadow is like a teacher showing all the mysteries of energy.

Xu Fei's body flying in the air gradually ceased to be a straight line, but showed a beautiful trajectory, and the explosion sound of those air bombs became smaller and smaller, turning into an extremely slight air flow sound.

Slowly, the body and the light and shadow gradually synchronized, from chasing to dancing in the air hand in hand. Xu Fei had long forgotten that his goal was to capture the light and shadow spirits, but subconsciously followed them and danced in the air.

This kind of dancing is like a dream, and there is no sound in this empty tower, like the body of an immortal and the light and shadow like an elf have a perfect resonance and harmony.

Suddenly, the light and shadow soared upwards and flew towards the beam of light at the top of the tower, and Xu Fei involuntarily flew upward, his hand already gently holding the light and shadow. At this moment, this light and shadow changed into the appearance of Dugu seeking defeat.

The two leaped out of the tower hand in hand.
