Shi Xuan watched his movements, initially wary.

The more she looked at it, the less aggressive the shadow seemed. It appeared to be demonstrating the spell to her, showing her how to unleash the attack, and that the attack struck the wall opposite Shi Xuan from behind.

Moreover, when that wave of energy was unleashed, Shi Xuan did not sense any fluctuation of spiritual power. It struck the wall behind him silently and without any reaction.

It seems that this is just a demonstration of the technique to the public.

Shi Xuan immediately recalled the years she and her senior brother spent in the illusion, when there was always a similar image in front of them demonstrating various skills. She figured the principle must be the same.

Shi Xuan quickly figured out the reason behind it; it was probably a test given by the nine-story pagoda, meant to teach her this technique.

Having figured this out, Shi Xuan looked specifically at the shadow in front of her. As she expected, after pausing for a while, the shadow quickly resumed its movements and began practicing the same routine again.

Shi Xuan observed the shadow's movements, deducing the flow of spiritual energy within him and the point of final exertion. Judging from the way he unleashed the shockwave, the grade of this technique must be quite high.

This is already the eighth floor of the nine-story pagoda, so it's impossible to give out ordinary third or fourth-tier cultivation techniques here.

Shi Xuan calmed down and carefully observed the shadow's movements. The movements were simple, just a few gestures: hand seals, waving, and turning around. But the difficulty lay in the flow of spiritual energy within the shadow—how it circulated, where it was concentrated, and how it was released…

These are not things that can be seen on the surface.

Therefore, this level is quite difficult to explain.

When they practice a cultivation technique, they usually place the book in front of them and study it, breaking down every path of spiritual energy within it and comparing it with the text.

Even so, many people still cannot master the techniques, and many advanced techniques can only be practiced by disciples with high comprehension.

But here, there's nothing but a shadowy figure, which is really baffling.

This wasn't the first time Shi Xuan had faced such a situation. She didn't move, staring at the shadow again, memorizing every detail it used.

But even if you remember all the details, it's not enough. It's just a set of movements. Who can see the flow of spiritual energy in someone else's meridians?

Shi Xuan frowned. Since this shadow appeared here, it meant that this technique could definitely be learned.

So, what are the key points to learning this set of exercises?

She reflected on the time she entered the nine-story tower, and it seemed that the tower had been training them all along, from the basics to spiritual power, and then to divine sense.

Moreover, from the fourth floor to the eighth floor, the training of spiritual consciousness progresses progressively. Especially on the eighth floor, the conditions for ascending the stairs are so stringent that ordinary people simply cannot perceive them.

Even after Shi Xuan discovered the method from above and told the four people who were already on the seventh floor, they still seemed completely confused and couldn't find a clue at all.

Therefore, Shi Xuan boldly speculates that the key here may indeed be related to divine consciousness.

She simply sat down, closed her eyes, and released her spiritual sense to feel all the movements of the shadow, using her spiritual sense to "see" the shadow's inner self.

Shi Xuan originally wanted to probe the shadow's body with his divine sense, just like he used to do when treating patients, to directly explore the internal situation, but the shadow was just a phantom and there was no such thing as "internal body".

There is no interior, only the exterior, and even that exterior is merely an illusion.

Shi Xuan's divine sense passed through nothing, but when it passed through that shadow, it seemed that it could sense something different about that shadow.

The feeling flashed by so quickly that Xuan couldn't quite grasp it.

But since there was this difference, Shi Xuan boldly explored in this direction.

She released all the divine sense she could muster, repeatedly passing it through the shadow's entire body. She quickly discovered that each time, the different parts were different; it seemed that the direction of the spiritual energy flow and the areas where it was concentrated would all show different characteristics.

So, is this the spiritual energy flow of this cultivation method?

Shi Xuan thought that if he continued to slowly experience it, he would eventually be able to figure out all the operating rules of this set of techniques.

But if that's the case, I don't know if the remaining ten days or so inside the tower will be enough to keep things going.

Fortunately, she still has the power of life.

Regarding the direction of spiritual energy, Shi Xuan guessed that the person who created this shadow must have hidden the direction of spiritual energy within the shadow, so that as long as a cultivator's divine sense is sensitive enough, they can sense it.

Shi Xuan sensed it, but at this speed, it was too slow and not intuitive.

Therefore, Shi Xuan decisively surrounded the shadow with the power of all things.

The fact that this shadow can automatically practice over and over again must be due to the support of spiritual power. In that case, the power of all things can certainly help Shi Xuan grasp the key points.

As soon as all things came into being, Shi Xuan quickly entered that profound state of meditation, just like when he was searching for the entrance on the seventh floor not long ago.

Everything on this floor seemed to grow larger and clearer, including the shadow's movements, which seemed to slow down.

While Shi Xuan was circulating the power of all things, he focused his divine sense back into the body of that shadow.

With the help of all living things, at this moment, everything about that shadow has nowhere to hide.

Sure enough, a very faint power existed within his body. As the shadow moved, that tiny power circulated throughout its entire body.

It really is the direction of spiritual energy!

If Shi Xuan had previously focused all his divine sense on the shadow to collect some "points" that would eventually be gathered into a surface and pieced together into a complete spiritual energy flow diagram, then now, this diagram was directly displayed in front of him, clear and easy to understand!

Looking at it this way, it really is quite complicated.

The flow of spiritual energy within the shadow's body is probably the most complex of all the cultivation techniques Shi Xuan has ever seen.

Shi Xuan couldn't help but gasp. If he hadn't seen the trend chart and relied on brute force to deduce it, even someone with the best comprehension wouldn't have been able to figure it out in just two or three years.

This nine-story pagoda is only open for a total of thirty days. Even if you spend all your time on the eighth floor, you still won't be able to learn this kind of technique!

No wonder that in all the previous nine-story tower records, there have been quite a few people who have made it to the eighth floor, but very few who have made it to the ninth floor.

Without the blessing of the All Things Grow, Shi Xuan didn't know if she would have had enough time to organize and learn this technique in the last fifteen days.
