Doudou was still too young, so she couldn't express herself very clearly.
But Shen Siyuan still picked up on something wrong from her fragmented words.
So he said to Yin Xingyue, "Xiaoyue, you and Doudou go take a look and see what the situation is."
Yin Xingyue nodded obediently, then looked at Doudou.
"Oh?"
Doudou was clueless, not yet knowing what was happening.
"Where did you see the big bad guy before, do you remember?" Shen Siyuan asked.
"Of course I remember."
Hearing this, Doudou put her hands on her hips and puffed out her tummy, seeming very proud.
"If you remember, then take Elder Sister to have a look."
"Oh~"
Doudou had a moment of realization, seemingly only just understanding.
Then she turned into a gust of Yin Wind, circled the room once, and flew out the window with Yin Xingyue.
Watching them leave, Shen Siyuan took out Embracing Wind Slumber and started flipping through it, mainly looking at the introductory explanations about wind and clouds.
Combining this with the Nine Nether Demon Lord's past knowledge, he felt a spark of understanding.
Back in The Great Wilderness, the Nine Nether Demon Lord had a movement technique called Rolling Clouds Unfurl.
Despite his title as the Nine Nether Demon Lord, the names of the techniques he practiced were all grand and magnificent, without a trace of ghostly aura. But they were Demonic Path techniques, after all.
Their cultivation methods were mostly unconventional, allowing for extremely fast progress, contrary to orthodox cultivation methods.
Take this Rolling Clouds Unfurl, for example.
It sounded like it had the detached elegance of watching clouds gather and disperse, but it was actually a technique to Control Yin Wind. Its speed was incredibly fast, and it was accompanied by the sound of ghostly wails that could sway a person's mind, capable of pulling a person's soul right out of their body just by hearing it.
It was quite terrifying.
However, Yin Wind was still wind, which gave Shen Siyuan a flash of inspiration by analogy.
Although this world had completely lost its Spiritual Qi, cutting off all methods of Cultivation Practice.
But he could use Underworld Qi to replace Spiritual Qi.
Although the Ten Thousand Souls Banner was damaged, it was more than enough for his own use. Once he repaired the Ten Thousand Souls Banner, the Netherworld Energy would be inexhaustible and could fully support his Cultivation Practice.
And as the Banner Master of the Ten Thousand Souls Banner, he wasn't afraid of being corroded by Underworld Qi and completely losing his sanity.
Of course, there would definitely be some effects on his body, but compared to the benefits, these effects were completely negligible.
However, Shen Siyuan didn't plan to try it right now.
Instead, with a thought, he summoned the Ten Thousand Souls Banner.
Then he formed a Hand Seal, and instantly, his vision shifted from his own body to Yin Xingyue's, seeing what she saw and hearing what she heard.
This was a basic ability of the Banner Master of the Ten Thousand Souls Banner: to be able to share the vision of the ghosts under his control.
Never mind Doudou next to her, who didn't notice Shen Siyuan's arrival; even Yin Xingyue herself was unaware of Shen Siyuan's presence.
The two of them rode the Yin Wind, spiraling and speeding through the air at an extremely fast pace.
Given the size of Binhai City, they should have arrived long ago.
Shen Siyuan was puzzled, but he quickly understood.
He saw Doudou flying in circles, muttering in the air, "It's right here, isn't it? How could I not remember…"
'Good grief, this little thing just swore up and down that she remembered the way. She's completely unreliable, only good for being a mascot.
'
But Shen Siyuan didn't say anything. He wanted to see how the two of them would handle it.
After all, if he was going to keep them around, they had to be useful for something.
Just then, Yin Xingyue took the initiative to ask, "Doudou, where is your Home?"
She knew this one.
Doudou immediately changed direction.
"There."
She pointed forward.
"Then let's go over there and have a look first."
Yin Xingyue rode the Yin Wind, heading forward.
"Elder Sister, wait for me."
Doudou hurriedly chased after her.
The sight of the two controlling Yin Wind and streaking across the sky was naturally seen by countless ghosts on the ground, leaving them stunned.
Some ghosts even tried leaping off buildings to ride the wind, but the result was that they were thinking too much. They simply floated lightly to the ground, completely unable to fly into the air, let alone ride the wind.
"I remember now, I remember now…"
The buildings on the ground finally looked familiar to Doudou.
Soon, the two of them landed on an Unfinished Building.
Through Yin Xingyue's vision, Shen Siyuan realized it was Peninsula Sunshine, Binhai's largest cluster of unfinished buildings.
Construction had only started for three years before it was halted due to a broken capital chain.
That halt lasted for over a decade, with no one ever taking over, eventually becoming Binhai's biggest eyesore.
The two Little Ones landed on the roof of an arc-shaped Unfinished Building.
This part was probably meant to be a shopping mall, as the entire structure seemed exceptionally large. He had no idea why Doudou would have come here before and seen the "big bad guy."
Yin Xingyue had the same question.
"Because of Chirpy," Doudou said.
"Who's Chirpy?" Yin Xingyue asked, confused.
"Chirpy is a little bird I found in the sky."
Yin Xingyue: …
It turned out she was worried Shen Siyuan would be lonely at home by himself, so she had left Home to look for her Sweet Potato Bwother.
But while she was in the air, she encountered a bird. She thought the bird was cute and unconsciously followed behind it, and then the bird led her here.
Although the process was a bit roundabout, the Little One was truly kind. A tiny little person with her Mom and Dad to accompany her, yet she still managed to think of Shen Siyuan.
"Where did you see the big bad guy?" Yin Xingyue asked."You come with me."
The Little One beckoned with her hand and walked forward with the air of a little boss.
The two of them made their way down from the rooftop, eventually reaching the fifth floor.
"Why didn't we just fly straight down?" Yin Xingyue asked.
Doudou froze for a moment, then gave a silly smile.
"Hehe, I forgot."
Yin Xingyue didn't know what to do with this little sister.
She looked around; it was deathly quiet and frightening.
Yin Xingyue was still a child, after all.
She instinctively shrank back.
Doudou, on the other hand, didn't seem to know what fear was.
She swung her arms and strode forward, and Yin Xingyue hurriedly followed.
Then, in a corner, they discovered a woman, naked from the waist up, tied to a chair.
The woman's head was bowed, her entire body a bloody mess. It looked like she was no longer breathing.
Doudou, who hadn't been the least bit scared just moments ago, immediately hid behind Yin Xingyue.
Yin Xingyue was also frightened into backing away repeatedly, but she still kept Doudou shielded behind her.
"I'm here, don't be afraid."
Just then, Shen Siyuan's voice suddenly rang out in Yin Xingyue's mind.
Yin Xingyue froze, then was instantly no longer afraid.
"Have Doudou stay to the side.
You go up and take a look," Shen Siyuan said again.
So Yin Xingyue turned her head and gave Doudou an instruction.
After hearing this, Doudou immediately scurried off on her short little legs, turned and ran, hiding in a corner and acting all sneaky.
"Banner Master."
"Call me brother."
"Brother."
"I'm here."
Hearing this, a calm and composed smile appeared on Yin Xingyue's face as she strode toward the woman in the corner.
Through Yin Xingyue's eyes, Shen Siyuan observed that the woman was likely already dead. Her body was covered in whip marks, a bloody mess, and on her chest, there was a Y-shaped burn.
This woman must have been tortured to death. The murderer was extremely vicious.
Yin Xingyue, who had originally mustered her courage with Shen Siyuan backing her up, couldn't help but feel a wave of fear, an emotion that was even transmitted to Shen Siyuan.
"It's alright, don't be afraid. Look around some more."
Shen Siyuan comforted her in her mind.
Hearing this, Yin Xingyue finally gathered her courage again and looked around.
Shen Siyuan then noticed an oil drum nearby.
Inside the drum were burnt ashes, and among the ashes was a fire poker. The burn on the female corpse's chest likely came from this.
Seeing that no one was around, not even the Ghost of the female corpse, Shen Siyuan had the two of them return.
