Li Muran was stunned and said, "If the senior brother gives me instructions, I will do my best. But my cultivation is shallow, and I am afraid I won't be able to help me."

"This is not necessarily the case." said the old man Tianjian: "Senior brother wants to ask his junior brother to understand a piece of painting paper full of runes, and this painting paper was left by the master before his disappearance."

"The runes left by Master Xuanguang?" Li Muran was shocked and showed a curious look.

The old man Tianjian carefully took out the jade box from his arms and handed it to Li Muran.

The old man Tianjian said seriously: "The runes on this drawing paper have been understood for many years, and even searched all kinds of rune classics, and there are no traces. The junior brother was able to make the Sky Sword Talisman, which shows that he is a genius in this field, and he may find something. The senior brother suspected that the runes on this drawing paper may be related to the clues of the master's disappearance.

Li Muran carefully opened the jade box and indeed saw an ordinary piece of silk paper, but there were dense runes on the silk paper, twisting like countless earthworms.

"These runes are messy, like children's graffiti. However, after all, they were left by the master, so they must have a deep meaning," said the old man Tianjian.

After Li Muran saw these runes, a hint of surprise flashed in his eyes.

"Why, can my junior brother recognize the mystery of this rune?" Seeing this, the old man Tianjian hurriedly asked.

Li Muran shook his head: "These strange runes seem to have been seen somewhere below, and they feel familiar. But they can't say it for a while, so it may take more time to carefully comprehend it."

The old man Tianjian nodded. Li Muran could not see through the runes that he had spent a lot of effort to comprehend.

"Okay, let's leave this drawing paper for the time being for the time being. Please understand it carefully. If you can really find clues from it and find out the whereabouts of your master, that would be a great achievement," said the old man Tianjian with hope.

"Yes," Li Muran agreed.

The old man Tianjian said goodbye and left. He turned into a sword light and sank into the void.

Li Muran looked blankly at the runes on the drawing paper, frowned.

At this time, a huge uproar had already occurred in his heart

At the first glance of seeing these runes, Li Muran immediately recognized that this was the Mirror Light Rune

Li Muran drew too many mirror runes, most of which were like this, like countless earthworms twisting, and they couldn't understand their meaning at all.

"The treasure mirror that Master Xuanguang once obtained was the other treasure mirror. The runes he left behind were the mirror light runes from the other treasure mirror."

"The two treasure mirrors are almost exactly the same, obviously they are complete sets of treasures. Although I only have one of them, I accidentally got part of the mirror-light runes of the other treasure mirror. Can I find some mystery from it?"

Li Muran was quite excited when he thought about this. He put away the drawing paper and entered the quiet room where he meditated, then opened the cave ban, and entered the Langyan Cave Heaven again.

Then he took out the mirror light rune he drew and carefully compared it with the rune left by Master Xuanguang.

Li Muran drew more than a hundred mirror light runes, each one was different, and none of these more than a hundred runes were the same as those left by Master Xuanguang.

Li Muran was not surprised by this. Over the years, the mirror light runes have been changing. The runes reflected by the same mirror are not consistent at different times, let alone the two different treasure mirrors.

"I wonder what the difference is between the runes reflected in the two mirrors?" Li Muran said in his heart. He compared the runes left by Master Xuanguang with the runes of his treasure mirror one by one, but except for finding that they were very similar, he did not see any rules.

"It was through these runes that Master Xuanguang realized the "Rebel Immortal Art" technique? What is the connection between this messy rune and a masterpiece of martial arts?

Li Muran studied it for a long time but still had no clue.

Not long after, Li Muran left Langyan Cave Heaven and his cave.

It was already night, and Li Muran was walking in the moonlight, but his mind was filled with the chaos of runes.

Although it was late at night, there were still many hard-working sword cultivators practicing swords in the Tianjian Valley. When they saw Li Mu, they saluted respectfully. When they saw Li Muran, they ignored them, so they did not dare to disturb them and continued practicing swords.

The figures of these sword cultivators in the air cast a faint shadow under the reflection of the moonlight and fell into the Sky Sword Valley.

Li Muran suddenly saw two shadows competing swords in front of him, and it seemed that the battle was very fierce, but there was no sound of swords fighting each other.

Li Muran looked up and saw a sword cultivator practicing swords in the air and in the sky. They were actually far apart and were practicing swords independently from each other, but the shadows happened to be leaning against each other. Only looking at the shadows, they thought the two were fighting swords.

"I took my preconceptions and made a mistake." Li Muran smiled slightly.

"Wait" Li Muran suddenly froze in the original place, a flash of inspiration in his mind, and suddenly something came to his mind.

Li Muran immediately turned into a ray of inspiration, flew back to the cave, and quickly opened the cave ban, inspiring Langyan Cave Heaven and entering it.

Li Muran took out the runes painted paper again and compared them with the runes left by Master Xuanguang again.

But this time, Li Muran overlapped the two painting papers, and then looked at a night pearl that shone with brilliant light, and saw whether the runes on the two painting papers could overlap.

As a result, he found that a small number of runes could overlap, but most of them intersect or do not contact each other. Overall, there seemed to be no mystery.

Li Muran changed another piece of drawing paper and continued to try to overlap with Master Xuan Guang's runes, but the result was still similar.

Li Muran tried one by one, and when he tried more than fifty, he was suddenly stunned.

He found that the runes on this drawing paper had no overlap or interlacing with the runes left by Master Xuanguang. However, the runes on the two drawing papers were exactly connected to the end, forming a complete figure.

This complete picture made Li Muran feel extremely familiar. After a moment of thinking, he immediately realized it.

"Ah, isn't this the meridian diagram of cultivation?"

Li Muran subconsciously tried to operate the true energy according to this meridian diagram. He took a deep breath and inhaled a large amount of heaven and earth vital energy. Then he slowly moved this vital energy according to the lines of the meridian diagram along the corresponding meridians.

However, after one cycle of heaven and earth was running, the vital energy of these heaven and earth was not trapped in the body at all.

"Strange" Li Muran was stunned. The more skilled he practiced, the more he could keep the more heaven and earth vital energy in his body, and refine it into the cultivator's own magic power. If the exercises were poor, the heaven and earth vital energy that could be refined every time he breathed was relatively less.

Of course, this is also closely related to the surrounding cultivation environment and the abundance of the heaven and earth's vital energy, but the amount of heaven and earth vital energy that each small Zhoutian can refine directly reflects the advantages and disadvantages of the exercises. This is the consensus in the world of immortal cultivation.

"Is this meridian diagram a little wrong?" Li Muran said in his heart: "Even if the skills are bad, they can at least be kept. Refining a little bit of heaven and earth's vitality will never be able to keep it at all."

Li Muran thought about it, and then used his magic power again according to the meridian diagram.

This time, he did not use the energy of heaven and earth to activate, but used his true energy and magic power to flow in the meridians.

A small Zhoutian, this true magic power was actually dispersed from Li Muran's body and integrated into the surrounding heaven and earth energy.

"Spread the merit?"

Li Muran was shocked. Isn’t this the exercise in the scattered part of the “North Immortal Art”? The exercise is also the biggest difference between the “North Immortal Art” and other exercises.

But Li Muran soon discovered that the two were somewhat different. According to this meridian diagram, the speed and effect of the scattering exercises were much more efficient than the scattering exercises in "The Unexpected Immortal Art"

"The "Reverse Immortal Art" is indeed learned from these runes," Li Muran said in his heart, "but, only half of the runes of Master Xuanguang can actually understand a set of martial arts. It's really a genius who is a genius, but I would never be able to do it."

Li Muran's knowledge and cultivation are completely incomparable to Master Xuanguang's back then. Master Xuanguang was able to rely on only half of the runes and half-information to establish the "Rebel Immortal Art" technique. Although it is only part of the true body period or below, it is already extremely valuable.

Li Muran immediately took out another blank piece of drawing paper and drew this complete meridian diagram on the paper.

He looked at the meridian diagram intently, and suddenly had an idea and turned the entire drawing paper backwards.

Because this rune is reflected by the light of a mirror, the real rune in the mirror should be the opposite of it, just like a person watching a flower in the mirror, but in fact the left and right sides are the opposite.

After turning the meridian diagram backwards, Li Muran then breathes in the vital energy of heaven and earth according to the lines of the meridian diagram.

This time, he had just started to operate a small Zhoutian and immediately felt something unusual.

All the heaven and earth vital energy he sucked into his body remained in his body, transformed into his true energy and magic power, without wasting at all; and, more than that, the heaven and earth vital energy around him was still rushing towards him quickly

His body instantly turned into a bottomless abyss, madly absorbing the vital energy of heaven and earth around him, and at an extremely efficient speed, it transformed into his true magic power

"Extremely Wonderful" Li Muran was shocked. This feeling of extreme speed of cultivation was just like the situation when he practiced the Nine Turns of the Immortals and Re-education after practicing the Nine-Turn Dispersion of the Immortals - even more efficient than that time

"The combination of two mirror runes is a truly brilliant practice method. This is a hundred times more brilliant than the "Reverse Immortal Art" that Master Xuanguang learned with half the runes."

Thinking of this, Li Muran became extremely excited.
