For the era of Swallowing Sun, Ye Li could often hear it from Swallowing Sun, and he also outlined an incomparably gorgeous world of spirit runes for him from the side.

At that time, there were many capable people, large sects dominated the world, and there were many strong people like carp crossing the river, which also made Ye Li yearn for it.

When talking to Tunri, Mu Rongxuan was already beckoning everyone to enter the stone room, and there was a sign hanging at the door of the stone room, and the attributes of each room were marked on it.

After taking a closer look, everyone chose the corresponding attribute to enter the stone room, and Ye Li naturally chose the fire attribute that he was best at.

Although each attribute can show different effects in boxing, after all, Ye Li's purest talisman root is still Huoxing, and it should be easier for him to start with this attribute first.

Together with several other disciples who also chose the fire attribute, they entered the stone room, and the rectangular rune frames on the ground that were two meters square met Ye Li's eyes.

These boxes are indeed made entirely of runes, each of which is carved with a special material that produces very strange powers.

When the door of the stone chamber was closed, the entire stone chamber became a strange space without the slightest aura.

Ye Li and the others felt very strange in this stone room, he felt as if something important was suddenly missing from the world around him, which made him feel uncomfortable.

It's like eating a plate of unsalted dishes, although the dishes are still vegetables, but they are difficult to swallow.

Holding back the discomfort in his heart, Ye Li and the others walked quickly to one of the rune boxes and stood still.

Just as they entered the frame, a layer of light rose from the frame, enveloping Ye Li in it, and then an extremely faint trace of fire aura was injected into the light mask.

When the Fire Movement Aura first appeared, Ye Li could still faintly feel its existence, but after it was completely integrated into the surrounding space, Ye Li could no longer feel this trace of Fire Spirit.

This extremely thin wisp of fire aura was like a small drop of ink dripping into a huge pond, and it disappeared without a trace except for what could be seen when it first entered.

At this time, Ye Li's task is to find and gather that little drop of "ink" in this huge "pool".

Ye Li, who was standing in the middle of the frame, had already closed his eyes, completely exuding his perception, and fully feeling the space within the entire light mask.

There has been no movement in the trace of fire aura in the space, and Ye Li has not seen even the slightest trace under his search.

"Senior Sun Swallower, is there really a trace of fire aura in this light mask?"

After some searching, Ye Li couldn't help but be suspicious, and secretly asked about Swallowing Sun.

Swallowing Sun smacked his lips, sat in the void, and said lazily: "Of course, there is a trace of fire aura, I can feel it, you can't feel it because your perception is too weak." ”

Hearing Swallow Ri's words, Ye Li couldn't help but be stunned, Swallow Sun wouldn't lie to him, it could feel it but he couldn't feel it, so it was obviously indeed his own problem.

"Ye Li, let me ask you, how do you think you can find a thin needle in a large pool of water?"

Squatting on the ground, Swallow Ri, who seemed to be smiling but not smiling, asked about it.

Ye Li was stunned and said, "How else can I find it, of course it's looking inch by inch......"

Speaking of this, he paused slightly, and then said: "Senior Swallowing Sun, do you mean that I didn't find it carefully enough, and I should look for it inch by inch in this space?"

Swallowing Sun shook his head, and continued, "If you replace that needle with a few fine pieces of iron filings, how will you find it?"

Hearing the second question of swallowing the sun, Ye Li was about to answer the question of looking for it inch by inch, but he opened his mouth but was suddenly stunned.

Because it was obvious that even if he searched inch by inch, it would be difficult to find these iron filings, after all, their volume was too small, inconspicuous in the water, and the slightest fluctuation would be washed away by the current, and it was difficult to find them at all.

Ye Li, who didn't know how to answer, couldn't help but be stunned in place.

Seeing that Ye Li didn't seem to be able to answer, Swallow Sun shook his head and said, "Because you are still a human being, your thinking flexibility is not as good as a demon beast like me."

I don't know if you've ever heard of a thing called a magnet?"

Swallowing Sun's words made Ye Li's eyes light up, and then an embarrassed look appeared on his face, and said, "Yes, why didn't I think that we could indeed use magnets to find these iron filings."

Even if you can't see their presence clearly, if you sweep the magnet in the water, the iron filings will come out of the hidden place and attach themselves to the magnet. ”

Swallowing Sun nodded, and said, "The wisp of Fire Spiritual Qi you are facing now is also in the same situation, like an iron needle or a few iron filings, which is very difficult to find.

Even if you search the space inch by inch with your senses, you will probably not be aware of its existence.

But there is a way to make them appear automatically, and that is to draw a spell, as long as you draw a fire walking charm, the fire spirit energy of this space will automatically appear and gather in accordance with the rules of heaven and earth to gather where your spell is activated.

Although this method does not help you in the slightest with your ability to gather the Fire Spirit, it can allow you to see how the Fire Spirit is hidden in this space.

As you use this method more, you will become more sensitive to the hidden fire aura, and it will be easy to tell the difference between them and the surrounding space.

After all, every time the spell is activated, as long as this wisp of fire aura moves, you will notice them, and you will be able to immediately compare the difference between them and the surrounding space.

After getting used to this difference, your observation will also improve, and even if you don't use this method, you will be able to quickly perceive the fire aura in the surrounding space. ”

Hearing Swallowing Sun's words, although Ye Li was somewhat skeptical in his heart, he immediately accepted this proposal.

He scattered his senses around, constantly scanning the empty space that seemed to be nothing special.

As his spirit yuan gathered, with a flick of his hand, the simplest fire charm appeared in his hand.

In the nearby space, in an inconspicuous hidden place, a wisp of pale red aura that was not much different from the surrounding space quickly converged towards the spell in Ye Li's hand.

However, this wisp of aura was too thin, and even after entering the spell, it could not activate the spell, and the spell quickly dissipated directly.

This wisp of fire aura that was captured once again disappeared into the void.
