Su Yun continued to walk forward with Xiao Zi, the light of the moon shadow flowers above his head was no longer visible, but patches of light began to appear on the ground, and when he leaned over carefully, he could find that these spots of light were some glowing bryophytes, these mosses emitted a faint white pure light, and a fresh and pure feeling slowly rose in Su Yun's heart, and these mosses seemed to have a will to purify everything.

The deeper you go, the more moss beneath your feet, and the faint glow on the moss dispels the darkness around you.

Walking out of this place full of light moss, Su Yun saw a spectacular scene.

This is a basin, and the high places around the basin are growing thick and tall moon shadow flower stems, these stems extend to the heights, grow towards the center, and finally gather together, becoming the "top cover" of the basin, floating above the basin one after another wonderful runes, these runes gather and scatter, time and minute, rotation and splicing, and repeat, each rune exudes a strong pure white light, as if all things were born as pure.

Looking down at the basin, the bottom of the circular basin is a regular Tai Chi Liangyi Sixiang Bagua pattern, which seems to have some connection with the floating runes above.

"Hey, what are you doing in a daze, come down." Xiao Zi took advantage of Su Yun's distraction and had already climbed under the basin alone.

After Su Yun climbed down the basin along Xiao Zi's path, he found that the gray walls around the basin were engraved with words.

The surrounding walls of the basin have become like stone and not stone, like jade and not jade, it looks like a surrounding jade wall, and the gray jade wall is engraved with white words, fortunately, this white is relatively bright, and it does not look difficult on the gray background.

"Brother can watch what he wants." Xiao Zi waved his finger and pointed to the surrounding jade bi, then took Su Yun's hand and ran over.

Su Yun suddenly realized, no wonder Xiao Zi read so many miscellaneous books, it turned out that these books were all recorded on the jade bi.

Su Yun looked along the jade bi for a while, but soon gave up, and watched speechlessly Xiao Zi beside him fly into the air easily, reading the words on the jade bi, Xiao Zi is currently a half-spirit, and he can fly at will if he wants to, but Su Yun can't fly.

The jade here is as high as more than ten zhang, and he can't see the words at the top, he can only see the words at the bottom of the jade, and the most important thing is that the words here are written vertically from top to bottom, so just looking at the text at the bottom, I really can't understand it at all.

Su Yun wandered around the huge basin.

This basin is not only the text on the surrounding jade, but also a large altar-like building in the middle of the basin.

There was a large area of lilac light streaks around the altar, and Su Yun walked near the light streaks and quietly stared at the swirling light streaks in the air.

Su Yun walked towards the altar, and the light patterns around the altar would automatically converge towards him, and then form a solid wall of light, making him unable to move forward.

Su Yun suddenly became interested in these light patterns.

From the moment he obtained the primary spirituality, he had a faint feeling that he seemed to be able to see through these runes, formations, prohibitions and the like, as if he was very familiar with these things, but in fact he couldn't tell the result, it was like a bunch of plausible, hazy handwriting, knowing that he could understand it, but he couldn't see it clearly.

Looking at the light streak in front of him now, he felt the same way.

He stretched out his hand to touch one of the flying light lines, which were blocked by his fingers and stopped in the air, Su Yun held this light pattern with his fingers, and looked at it carefully close to his eyes.

It can be seen that this light pattern is composed of one fine ray after another, the small light light forms the large light, the large light is woven into the light pattern, and the small light is connected by one fine rune after another, and the fine small rune can be broken into one fine line after another......

Seeing this, Su Yun's head suddenly dizzy and fell directly to the spot.

When he woke up, he was lying on Xiao Zi's bed again.

He sat up from the bed suddenly, thinking that he had triggered the traceback, but when he saw Xiao Zi standing by the bedside, looking at him worriedly, he suddenly understood that it was he who fainted by looking at those light lines, not the traceback.

He looked at the sweat on Xiao Zi's cheeks, and knew that he hadn't passed out for long, and that Xiao Zi had carried him back here.

Thinking of such a long road between the immortal tomb and the wooden house, Su Yun suddenly felt a sense of guilt in his heart.

"I'm sorry, Xiaozi, I'm tired of you." Su Yun reached out to help Xiao Zi wipe the sweat off her forehead.

"It's okay, big brother, you're fine." Xiao Zi showed an innocent smile.

Su Yun sighed and ate a few moon fruits placed next to the bed.

His brain was a little groggy, which made him realize that the consumption he had just seen the light pattern was too great, he looked at his spiritual power and found that the spiritual power was still full, which meant that what he had just consumed was not spiritual power, it should be a deeper and more original thing.

To be precise, it should belong to mental strength, and his current state is a bit close to mental haggardness.

Su Yun thought back to what he had seen before, dissecting a light pattern from a microscopic level, and then microscopicly, it may be that this process of analysis exhausted his mental strength, but one thing he was sure of was that he had an almost innate sensitivity and familiarity with this kind of rune-like thing, he didn't know where this familiarity came from, but he knew that this familiarity had a lot of potential to be explored.

But the cost of this excavation process should be very high, because this process consumes mental energy, and the state of mental emaciation will continue forever, even if it is backtracked, it cannot be directly removed, which is different from material exhaustion.

This also means that he can't use the way of reincarnation to spend his mental energy to study the runes over and over again, and every time his mental strength is haggard, he has to spend time to recover, but fortunately, after regression, he can use nine times as long to recover his mental strength, which is also a time saving.

Thinking of this, Su Yun's heart couldn't help but itch, looking forward to his mental strength recovering as soon as possible, and then continuing to study that piece of light.

Su Yun lay on the bed for a whole day before he recovered his spirit, and after he chose to go back, he immediately rushed to the immortal tomb and continued to study the light patterns near the altar.

Soon, he passed out again, but this time it was different, he discussed it with Xiao Zi, after he passed out, Xiao Zi didn't need to move him, because he had already taken the bedding to the fairy tomb, and when he passed out, he covered the futon and slept for a while, and calculated the time node of the backtrack, so that Xiao Zi could wake himself up at that time.

Although Xiao Zi felt that it was strange for Su Yun to do this, she didn't ask any questions, and did as Su Yun said.

And as Su Yun analyzed the light pattern again and again, finally when he analyzed the light pattern for the eleventh time, he felt that he had seen the most root thing.

It was one line after another, and it was certain that the lines he saw were beyond his horizon, and this was not what he saw with his naked eye, at most he could only see clearly the lines that made up the light lines, and further down, it was what he saw with his consciousness, although his eyes were still staring at the light lines, but in fact, there were other things that felt the light lines.

He didn't know what it was, but he saw it as if it were all clearly unfolding before his eyes, even though he knew it was something that had gone on a myriad of microscopic levels.

These thin lines are dense and endless, but they are extremely familiar in Su Yun's eyes.

But familiar is familiar, Su Yun still can't comprehend the principle, but he can see according to these dense thin lines, the runes composed of these thin lines have three effects: luminescence, levitation, defense, and three.

His horizon rose from the thin line level to the top of the line, and he began to observe the effect of multiple rune combinations, and amazingly, he understood the principle of multiple rune combinations at a glance:

The energy links that these runes communicate with each other are in the form of light, so these runes can emit light.

In terms of rune structure, these runes are able to convert the received light energy into a self-magnetic field, resisting the gravitational magnetic field between heaven and earth, so they can levitate in the air.

When multiple runes are placed in close proximity, energy bonds are created between the runes, forming a tight and strong rune array, creating a strong defensive effect, but consuming additional energy.

Just like the carbon element in chemistry, when it is loose, it is coal, which can be used to burn fire, and when closely packed under high pressure, it will form hard diamonds, or even diamonds, the same element, demining is different, and the properties are very different.

These seemingly glow-only levitating light streaks can also be a strong defensive shield if properly arranged.

After understanding its principle clearly, Su Yun instantly understood how to crack these light pattern shields.

He picked up a light pattern, then stretched out his hand and walked towards the altar, the light patterns around him quickly gathered over, Su Yun drew the light pattern in his hand on the light mask that had not yet formed, and suddenly the massive light pattern seemed to stick to his hand, and it was connected with the light pattern in his hand.

Before the light mask was formed, it fell apart under Su Yun's hand.

This cracking method seems simple, in fact, there are infinite mysteries inside, first of all, you can see through the efficacy and principle of these runes, and then you need to think clearly about the weaknesses between the structures of these runes, and finally you need to grasp the time to crack.

Of course, a violent attack mask is also a way to crack it, but Su Yun believes that the defensive shield left by an immortal, with his own ability, should not be able to break through.

After Su Yun walked into the light mask, the light patterns around the altar suddenly rotated, and then gathered towards the middle of the altar, and the dense light patterns were spliced together on the altar, forming a ball, and the rune ball glowing with light purple light slowly rotated in the air, with gilt golden words on it.

A figure sat in the middle of the rune orb.
