Who taught him to practice swordsmanship like this?

Su Baichen also temporarily stayed at that villa.

In theory, the elders of Changchun Palace should be discussing how to deal with the demonic forces, while Su Baichen should be heading to the capital.

but……

What could be more important than finding the bad guys inside your own organization?

A group of elders from Changchun Palace gathered together to begin 'scientific research'.

Based on the information they currently possess, they plan to work together to develop skills targeting those supernatural beings and spirits.

Of course, these discussions were conducted separately by each sect, since different sects have different traditions and therefore different methods.

Su Baichen was the first to propose his idea: "Since they are not afraid of the black cage, could we use the black cage to identify them?"

Good grief, so anyone who isn't controlled by the black cage is a bad guy, right?

The requirements for the Black Cage are much lower than those for the Illusion Realm.

Master Xuan Yin praised, "Indeed, all we need to do is design a screening mechanism, and it will be immediately clear whether someone is under the control of the Black Cage."

"However, this technique can only be used on a single target; it would be quite difficult to use it over a large area."

Su Baichen started talking, and Shui Yinji, who had come with him, said softly, "Senior Brother saw through soul searching that those strange souls came from a dark and chaotic place. Could we recreate that scene using illusion magic to expose the strange beings?"

Master Xuanyin said, "There's a problem. They clearly possess a different sensory ability, or rather, a spiritual awareness, than ordinary living beings. Ordinary darkness is probably useless..."

Su Baichen pondered for a moment and said, "Master, I think Uncle Shuiyin's statement makes a lot of sense... Assuming the key to the other party breaking through the black cage's confinement lies in their spiritual perception, why not try to use our understanding of darkness to suppress their spiritual perception?"

The old fisherman clapped his hands and said, "This idea is correct; it's at least very effective against beings weaker than us."

Master Xuan Yin stroked his beard and said, "In that case, in recent years, when I cultivate, I have been able to sense a void of darkness more and more, and that feeling is somewhat similar to the source of the strange souls obtained through soul searching."

"Let me try..."

Master Xuanyin pondered for a moment and then had an idea, asking, "Who will give it a try?"

Shuiyin Ji and the fisherman both looked at Su Baichen...

Goodness, you all know that being in a black cage is no fun, right?

Su Baichen could only bite the bullet and say, "Then let this disciple do it..."

Master Xuanyin smiled and said, "Don't worry, it will only be for a short while. But you should carefully observe the details here and look for any mistakes or omissions."

A moment later, Su Baichen personally experienced the taste of the 'Black Cage'.

All five senses are sealed off; self-awareness, sensitivity to qi, and perception of divine thoughts are all lost.

These are the eight kinds of "awareness" targeted by the Eight Transformations of Illusion. Theoretically, if all eight of these awarenesses are stripped away, a person will completely lose their perception of the outside world.

However, Su Baichen had a different feeling at this moment.

When all eight senses are taken away, his spiritual awareness becomes deeper and clearer.

He even saw a more vibrant world...

Under his spiritual vision, what he "saw" was not an unchanging reality, but rather that everything around him seemed to be "moving".

Just like the person in front of him, he could sense that his master, Xuan Yin Zhenren, was a sphere interwoven with black and white.

It is white inside, but has some black spots.

The black exterior is constantly intertwined and transformed with the white exterior, like the yin and yang symbol.

He further noticed that the white part was constantly releasing the black part during this interweaving and transformation process, as if it were being purified...

The next moment, this strange spiritual perspective disappeared, but it didn't completely disappear; it was just covered by a 'black veil'.

He guessed that this might be the "Black Cage" that his master had modified?

This 'black veil' did indeed cover his last window to the world, but it was clearly not completely covered.

He could still vaguely sense the outside world...

A moment later, all his senses returned.

"how?"

Xuan Yin Zhenren immediately inquired after unlocking the "black cage".

The fisherman said dismissively, "What could you possibly feel in such a short time?"

Shuiyin Ji asked with concern, "Bai Chen, are you feeling unwell?"

Master Xuanyin also explained, "The 'Black Cage' is terrifying in itself. Even if it only imprisons a person's consciousness for a short while, the inability to see anything will drive a person insane."

The fisherman chuckled and said, "How could I not know about the 'Black Cage'? I also know Bai Chen's abilities; the mere 'Black Cage' shouldn't be able to hold him."

As soon as he finished speaking, Su Baichen came to his senses. He first thanked Shuiyin Ji: "Uncle-Master, I'm fine. Thank you for your concern."

He then said to Master Xuanyin, "Master, it has some effect, but it can't completely block out the spiritual senses."

Xuan Yin Zhenren was intrigued and said, "Let me experience it too."

The fisherman said, "Alright, I'll perform the spell on you."

As he spoke, he used the same improved version of the "Black Cage" on Xuan Yin Zhenren.

A moment later, Master Xuanyin broke free of the illusion and realized what was going on, saying, "I understand what you mean. Spiritual perception is a realm that the Eight Transformations of Illusionary Yin does not touch. We try to make up for it with our own understanding of the darkness through spiritual perception, but we are ultimately just missing the mark."

"It seems almost impossible to deceive the senses of living beings."

Master Xuanyin said regretfully, as if he felt that this line of thinking was not working.

Princess Mizukage was somewhat disappointed.

However, Su Baichen changed his mind and came up with another idea.

"Master, think about it from another perspective. Most of these superhumans don't have much cultivation. At least our initial target should have been those superhumans with little cultivation."

"We don't need to use such a high-level illusion as 'Black Cage' to deal with them."

"Since they can see through many illusions because of their abnormal spiritual senses, why don't we try deceiving their spiritual senses instead of completely shutting them down?"

Master Xuan Yin asked solemnly, "Tell me your thoughts in detail?"

Su Baichen first shared his feelings about being in the "Black Cage": "In the Black Cage, my eight senses were taken away, but my spiritual senses became clearer."

"Therefore, I believe that the eight senses do not necessarily need to be taken away completely; keeping them can actually interfere with spiritual senses."

Master Xuan Yin's eyes lit up upon hearing this: "That makes sense, this line of thinking is very correct!"

He paced back and forth, then exclaimed excitedly, "I have another idea!"

"The seven senses can be retained, except for sight and spiritual sense... or the senses of hearing, touch, and smell can be weakened and adjusted to create a feeling similar to the edge of nothingness."

He found his direction: Xuan Yin Zhenren, who had already begun cultivating to the upper realm of the Nascent Soul stage, had his own genuine understanding of this level, so creating illusions based on this would naturally be twice as effective.
