As soon as the Hundred Treasures Sack was taken out, the scene around Su Yun suddenly changed, layers of red and white mist rippled in all directions, especially gorgeous, like a dream.

Before Su Yun could react to what exactly happened, a large number of light pillars shot up around him. These light pillars were especially dazzling, and their colors were different. The light pillars continued for a long time before they slowly disappeared. Su Yun looked over again, only to discover that each light pillar was an exquisite box the size of a palm.

“They’re all treasures. Su Yun, you’re rich.”

At this moment, a voice suddenly sounded from beside him.

Su Yun was shocked and looked sideways, only to see Ling Qing Yu standing beside him at some unknown time.

“Qing Yu… When did you come out?”

“You dragged a statue into the sword box. How could I not know?”

Ling Qing Yu rolled his eyes at him and said, “I have comprehended something during this period of time, so I have been cultivating inside. It’s rare for me to be quiet. Something happened to you again.”

“The situation is urgent. I have no choice.”

Su Yun said apologetically.

“You bastard, I haven’t seen you stop since I met you.” Ling Qing Yu snorted, then looked around and asked, “Where are you now?”

“The forbidden area of the True Devil Sect’s ancient tomb, the garment grave of the previous Great Devil of the True Devil Sect.”

Su Yun laughed.

“No wonder the demonic energy here is so dense.”

Ling Qing Yu frowned and his gaze fell on the treasure boxes in the surroundings. He said, “Open these boxes quickly and see what kind of treasures are inside.”

“Yes.”

Su Yun did not hesitate and opened the treasure box inside.

Inside the first box was a small piece of iron the size of a round copper coin. The iron piece was stained with rust, and there was nothing remarkable about it. Su Yun pinched it up, carefully examining it for a while, there was no profound energy, no energy fluctuations, not even the slightest bit of halo…

“Is this also a treasure?”

He was puzzled.

“The quality of an item is not based on its surface, but on the energy contained within it. It depends on its nature. However, this item should not be a magic treasure, or perhaps it is just a material.”

“Keep it for now. Perhaps my current cultivation is low, so I can’t tell how powerful it is.”

Su Yun put the iron sheet into the box and threw it into his space bag.

Open the second box.

The box was empty, but it spat out a ray of light, sprinkling all around. In an instant, a large number of golden words appeared on the light screen around Su Yun.

He looked sideways and carefully read it. He discovered that it was actually a mental art.

“When I smell it, the devil leans towards my heart. Both the real and the real are dreamy, burning in the light and darkness.”

“Both static and dynamic are one. Yin and Yang seem to be one. There is no space between heaven and earth. The sun and moon seem to be connected.”

“Only one’s heart can accommodate it, not an inch from one’s soul. Fu Hui has nothing to ask for, and calamity and evil have nothing to fear.”

“The Void Soul Body is at ease. It has hidden itself from the crowd. It flicks its finger and surpasses the Beginning. Chaos dawns in all living beings. It will forever exist in the shadows.”

…

Su Yun stared at the words and read them carefully.

After a round, the two of them both had their own insights.

“This seems to be a profound technique about illusions.”

Said Su Yunchen.

“En … and it’s very exquisite. I wonder which expert created it. These words and phrases are all three souls and seven souls of Ling Xuan. It’s truly admirable.” Ling Qing Yu stared at the words and said, “Su Yun, sit down cross-legged and start practicing.”

“Practice?” Su Yun was stunned, “What? Do you want me to cultivate this mental art now?” The practice of martial arts can’t be accomplished in a day, let alone in a hurry. Besides, the conditions here also don’t allow it. ”

“Idiot.”

Ling Qing Yu cursed and pointed at the treasure box, “Don’t you understand? You only have one chance.”

“What chance?”

Su Yun felt puzzled, his gaze shifted to the treasure box, but with just a single glance, he was stunned.

At this moment, the treasure box was slowly cracking and decaying. Previously, it was dazzling, but now, it had become ordinary…

“The treasure box is self-destructing?”

Su Yun said with a solemn brow.

“That’s right.”

Ling Qing Yu nodded.

“Self-destruct, self-destruct. These words are only three hundred words and can be memorized with a single glance. I have already memorized them in my chest. So what if I destroy them?”

“Three hundred words of mental energy isn’t much. Not to mention spiritual cultivators, even ordinary mortals can probably remember all of them in a short period of time. If that’s the case and destroy the box that contains the mental energy, don’t you think it would be too much?”

Ling Qing Yu approached the box. She closed her eyes slightly. He seemed to be feeling it, A moment later, he opened his eyes and said, “However, the owner of the box would not do such a useless thing, “Su Yun, this box is self-destructing while emitting a wondrous energy. This energy seems to be a prerequisite for cultivating this mental art. Su Yun, if you don’t start cultivating quickly and wait for this box to self-destruct, then you will miss out on this peerless mental art.”

Hearing Ling Qing Yu’s words, Su Yun suddenly realized, how dare he hesitate? He immediately sat cross-legged in front of the treasure box, closed his eyes, and began to circulate his Qi according to the descriptions in the surrounding mental arts.

The speed at which the treasure box self-destructed was not very fast. According to preliminary estimates, Su Yun had at least eight hours to cultivate.

However, what kind of mental technique could be learned within eight hours? If he were to learn it like this, there wouldn’t be any mysteries to this mental art, right?

Everything is cyclical and gradual, haste makes waste. Is it really powerful for this mental art to require people to cultivate so quickly?

He thought so, but after carefully comprehending it, Su Yun realized that he was wrong.

There was Yang in Yin, reality in Void, Sun and Moon connected, Heaven and Earth were inseparable. This mental technique was clearly the illusion technique that the Great Demon Shadow Guard had used to deal with him! !

To tell the truth, the previous test Su Yun did not actually defeat the Shadow Guard. Instead, he took advantage of the opportunity and controlled the statue. Only then did he complete the test. If he only fought against the Shadow Guard head-on, relying on that strange attack method, it would be very difficult for Su Yun to win.

He hadn’t expected that he would have the chance to learn such a mental technique.

Su Yun sighed in his heart, but at the same time, he was overjoyed.

This Mysterious Technique Heart Technique had a very domineering name, called the Yin Yang Wanxiang Art. There was only one layer of the entire Mysterious Technique, and one could only learn it. It was the purest illusion technique, but it was also the most complex one. The most important thing about this Mysterious Technique Heart Technique was that it could be collected freely as one wished. Once this illusion spell was born, it was equivalent to forming an absolute domain around him. Anyone who approached this domain could forcefully drag in and enter the illusion realm. And the so-called illusion realm was Su Yun’s own world. He easily disguised his offensive, causing the extremely ferocious killing move to become completely useless. The clouds were light and the wind was gentle, making people unable to defend against it.

Who wouldn’t love such a profound technique? Su Yun earnestly comprehended every word in his heart technique, his eyes focused and concentrated.

It took eight hours to practice a profound technique, and one could imagine how difficult it was. At this moment, Su Yun not only needed to comprehend them, he also needed to practice according to the meaning above and master them. According to what Ling Qing Yu said, this treasure box was self-destructing while emitting a unique energy. This energy was a primer for Su Yun. Only its traction could allow Su Yun to successfully learn the Yin Yang Myriad Symbols Technique.

Illusion was the most common mental spell. However, illusions were also extremely varied. Some illusions could change one’s image, while others could submerge the earth, mountains, and rivers. Some powerful illusions could make a Spirit Cultivator forever immersed in illusions and unable to extricate himself. This was a spell that used spiritual fluctuations as a carrier to spread out in all directions, thus affecting the consciousness and spirit of others. As the saying goes, attacking the heart was the most important, while illusion was a method of attacking the heart. If one controlled the consciousness and spirit of a spirit cultivator, how difficult would it be to defeat that spirit cultivator?

Su Yun raised his hand and gently shook it. His eyes were closed, and his not-so-powerful mental fluctuations began to tremble.

According to the description in the Wanxiang Art, he began to try to spread out his spiritual energy.

This wasn’t a difficult matter. Not long after, Su Yun successfully spread his spiritual energy. Although it wasn’t strong, it was still enough. After all, this was the first time he had practiced such a profound spiritual spell.

Of course, it was far from enough to learn how to release spiritual fluctuations. This Yin Yang Myriad Symbols Art was between the real and the real. It was between the Yin Yang and the world. What it pursued was not the pure illusion in the illusion, but the real within the illusion, the real within the real, the real and the virtual, making it impossible for people to distinguish between them.

If it was just an illusion, how powerful would it be? Just like the Void Spirit Sage back then, he had clearly controlled Su Yun, but it was difficult to destroy his spirit and make him take advantage of it.

However, the Wanxiang Art was too exquisite, and the requirements for controlling mental fluctuations were extremely high.

Its activation is not an incantation, To be able to cast an incantation, what it required was to be able to unleash a profound technique at any time, quietly come, quietly leave, so that the opponent would not be able to sense that he had been dragged into an illusion. This was not a requirement for speed, but for reactivity and proficiency. Of course, it also required extremely high and stringent control of mental fluctuations.

Fortunately, although Su Yun did not understand spirit magic, his spirit was strong enough. After experiencing so much, his spirit was especially firm and strong. It was not difficult to learn this Yin Yang Myriad Symbols Art.

Ling Qing Yu stood at the side and looked at Su Yun without blinking.

As the treasure box slowly self-destructed, the surrounding Heart Technique fonts gradually lost their luster.

Su Yun looked over word by word, experiencing it word by word. At first glance, he thought that three hundred words were very simple, but now he saw that three hundred words were too many. Time was tight, and he couldn’t waste a single second.

Time slowly passed.

“Three hours have passed.” Ling Qing Yu was rather anxious and murmured, “Can this fellow Su Yun succeed?”

Su Yun’s calm appearance made her a little anxious.
