Who taught him to practice swordsmanship like this?

The Yin Fu Sect's headquarters was a huge pavilion hidden within a large illusionary barrier.

This pavilion is located on the edge of a cliff in the strait and is built entirely of submerged wood.

Its size, based on Su Baichen's memories of his previous life, is similar to the main south gate of Xi'an...

However, the plaque above reads: Yinfeng Pass.

Su Baichen asked in surprise, "Why this plaque?"

As Xuan Yin Zhenren led Su Baichen inside, he said, "As the name suggests, this is Yin Feng Pass."

"It's just the Yinfeng Pass from ancient times. Back then, large numbers of ghosts often appeared in this Yinfeng Gorge, so the 'Yinfeng Pass' was built here to guard it."

"There are actually quite a few similar passes. Our Changchun Yin Sect has chosen this place as our base, which is actually an inheritance of the mission of our ancestors to guard Yinfeng Gorge."

Su Baichen was a little worried. Could it be that his small body would have to deal with the dirty things in Yinfeng Gorge?

Feng Linzi comforted him, "What are you afraid of? This Yin Feng Gorge was a disaster and a threat to our early ancestors. But for us, it is an important treasure trove of resources."

Su Baichen didn't quite understand.

They had already entered the gate tower.

Upon entering, one is greeted by a spacious, empty hall.

Two disciples approached and said, "Sect Master, Senior Brother, you're back."

It seems that the elder of the Yin Fu Sect is not just Xuan Yin Zhenren; these two disciples are someone else's disciples.

Master Xuanyin asked a couple of questions casually, and then led the way to the back of the main hall.

Feng Linzi explained, "Besides disciples like you who were assigned from Changchun Palace, the various senior uncles in the sect also bring back disciples they have their eye on from time to time."

"However, these disciples are different from you. Their names are only in the Yin Sect and not in the Changchun Palace, so they cannot be considered true disciples. Unlike you, who are already true disciples."

Su Baichen immediately understood Feng Linzi's unspoken meaning: These disciples whom the Yin Sect elders had taken in themselves might be hostile towards him, the junior brother who had become a true disciple without "doing anything"?

However, he didn't care too much. After all, in his opinion, as long as he could experience the wonders of cultivation, nothing else mattered.

They came to the back of the hall and saw a huge space that stretched vertically downwards.

A seemingly endless series of staircases surrounds this enormous space, and there are countless staircases both above and below them.

Seeing him looking up, Feng Linzi explained, "This staircase leads to a watchtower, which belongs to the Yin Feng Pass itself. As for down..."

Just as he was about to continue, Master Xuanyin suddenly interrupted him: "You and I should go down first. Let him climb the stairs by himself."

Su Baichen was taken aback.

Feng Linzi replied apologetically, "I'll wait for you downstairs."

As he spoke, Xuan Yin Zhenren had already leaped down into the huge void in the middle of the stairs.

Feng Linzi followed.

Su Baichen looked around at the dim light and swallowed hard.

He didn't think much of it; after all, he couldn't expect his master and senior brother to climb the stairs with him, could he?

However, the gap between these staircases is over a hundred square meters, and looking down, it's like a bottomless abyss of despair.

Su Baichen's legs were still trembling a little, but fortunately it was so dark that he couldn't see how deep it was, which relieved some of the fear brought by the height.

He walked down step by step.

The light is getting dimmer.

But he discovered that he wasn't as afraid of the dark as he had imagined.

And gradually it didn't seem so dark anymore.

Walking in the darkness, he suddenly felt that he himself was a source of light; he only felt darkness before him, while he himself was the light.

The true energy accumulated in the dantian for three months is a light source that can illuminate the darkness, and even the gradual chill in the surroundings is dispelled by this true energy.

As Su Baichen found himself in darkness, a vision suddenly appeared in his mind: he transformed into a bright little ball of light, surrounded by a huge black ball of light.

He himself represents Yang, while everything around him is Yin...

He felt that this scene was very mysterious, and it was subtly conveying some information to him, but he couldn't quite grasp it at the moment.

For a moment, he forgot where he was, mechanically walking downhill while scratching his head and racking his brains.

Suddenly, he remembered what Master Kaiyang had said to everyone today when introducing the Yin Sect: The characteristic of the Yin Sect is to generate Yang from Yin.

The description of "yin giving rise to yang" immediately connected him with his current environment.

In this sudden realization, he subconsciously stirred the 'yin' in the surrounding darkness, causing it to accumulate around him.

He actually managed to attract yin energy!

As he drew Yin energy to surround himself, the true Yang energy within his body reacted accordingly.

Under the pressure of the surrounding yin energy, it became purer, more solid, and more resilient.

What was originally a long and arduous process of going downstairs turned into a form of cultivation, and time flew by...

Finally, he felt the light again and smelled the fresh air.

However, he was completely absorbed in his cultivation at this moment and no longer cared about anything else...

……

Feng Linzi was waiting outside the "Stairway to Heaven".

He was somewhat worried that Su Baichen was still so young and might not be able to withstand the oppression of loneliness and the abyss in the darkness, causing some psychological trauma.

But there was nothing he could do; he knew this was a test given to him by the Mysterious Yin Immortal.

Master Xuan Yin was a very strict teacher. Since Su Baichen had become his disciple and a true disciple of the Yin Sect, he had to undergo the corresponding tests and bear the same responsibilities.

Feng Linzi was quite worried about Su Baichen, but fortunately he still heard footsteps coming from inside.

But he immediately sensed something was wrong. Why did he feel the yin energy in the area was abnormally accumulating as the footsteps approached?

Although Yin Feng Pass is inherently rich in Yin energy, but...

He suddenly saw Su Baichen's small figure break through the dense cloud of yin energy and step into the light, her body covered in a chilling frost.

"Phew~"

Su Baichen exhaled a breath, and the white mist formed a pillar, which was quite spectacular.

He felt his mind was frozen by the yin energy, and when he saw Feng Linzi's serious expression, he suddenly realized that he had probably acted recklessly again.

His somewhat rigid thinking immediately returned to normal, and he said shyly, "Senior brother, I was a bit bored on the way here, so I was thinking about it... I don't know how to absorb this yin energy, so it shouldn't be a bad thing, right?"

Feng Linzi's eyebrows twitched, and he felt a sense of powerlessness.

This junior brother hasn't even learned a single word of the Profound Yin Qi Technique, yet he's already mastered half of it!

He asked, "How did you come up with that idea?"

Su Baichen replied, "In the darkness, at first I felt very lonely and cold, but then I remembered what Palace Master Kaiyang mentioned this morning about the core tenet of our Yin Sect being 'Yin giving rise to Yang,' and I felt that the outside world was Yin and the inside was Yang... and that's how it was."

It was said lightly, but this statement really left Feng Linzi somewhat speechless.

However, given his own precedent of achieving enlightenment through swordsmanship, it's not entirely outrageous...

No way, that's absolutely outrageous!
