The Brain in a Vat is actually called Du Zhong, which is also the name of a certain medicinal herb.
Perhaps because he only had one brain left, his mind was very active. He spent the whole time reading comics, novels, and watching movies, and would occasionally pull Hu Jiu aside to discuss the plot.
According to him, he lost all his bodily senses and needed to constantly receive new external information in order to feel that he was still alive.
Hu Jiu had no interest in discussing plot points; he only loved absolute selfishness, complete self-interest, and the ruthless killing of anyone who disagreed. If he couldn't win, he would quietly develop his strength and then continue killing once he became powerful enough...
Du Zhong, however, spent his days immersed in all sorts of supernatural and melodramatic novels about rebirth, being born with supernatural powers, and defying the heavens.
The environment of the Ghost World is complex and ever-changing, much like a patchwork of various open Ghost Domains. You might only take a few steps before the surrounding scenery changes, and there may even be certain patterns of killing. Once triggered, you will be attacked by wandering Fierce Ghosts.
Fortunately, Hu Jiu is quite powerful. He is skilled in Phantom, mirror images, dreams, Disasters, charm, Supernatural suppression, Supernatural Games, rule making, and mind visualization, making him an Omnipotence all-rounder.
So far, apart from the enormous Red Moon in the sky that made him feel uneasy, he had been as relaxed as if he were taking a walk at home.
Hu Jiu did not exchange information about Du Zhong's abilities, but through observation, he could discern several abilities Du Zhong possessed, including intelligence reduction, reverting to a past state, and information perception.
Restoring oneself to a normal state is probably a kind of time Rollback or downgrade. Du Zhong gets mentally fatigued from reading too many novels and comics, he refreshes himself and then continues reading.
Information perception means that Du Zhong can collect information from extremely far away and avoid dangerous or troublesome places in advance.
Hu Jiu was fairly satisfied with Du Zhong as his pet.
At least it actually works.
"Your current appearance is somewhat bizarre. Do you want me to sculpt a body for you?" Hu Jiu asked.
"Huh?" Du Zhong snapped out of his comic book world and asked, "You can even shape people with your bare hands?"
"Of course!" Hu Jiu snapped his fingers, and Phantom of a human youth appeared in front of him.
The Phantom gradually solidified, transforming from illusion into reality, becoming a real body—tall, strong, with delicate features, except for slightly small eyes, a bun hairstyle, and a strange long fringe...
Hu Jiu ripped open the body's skull and beckoned to Du Zhong, "Come on, shove your brain back in."
Du Zhong: "..."
"This look won't do; she looks too miserable. Find someone else!"
"Okay." Hu Jiu then conjured up the image of a boy with blond hair, blue eyes, and a few strange fox whiskers on his face.
Du Zhong: "This person seems to have had an unhappy childhood."
Hu Jiu: "You're so pretentious. Just draw one that you're satisfied with."
Du Zhong drew a pink starfish wearing underwear.
Hu Jiu: "... I'm glad you like it."
"Anomaly detected ahead!"
Du Zhong, who was engrossed in playing the Miracle Little Du dress-up game and completely absorbed in it, suddenly gave a serious reminder.
"What happened?" Hu Jiu asked, looking ahead.
His field of vision quickly extended, and then he saw a vast expanse of white.
"It looks like sunlight?"
The sky above the Ghost World was dominated by Red Moon, making the sun a mere backdrop. They hadn't seen such bright and dazzling sunlight in a long time.
"Should we avoid this place?" Hu Jiu asked Du Zhong.
Du Zhong replied, "It's too late; there's no way to avoid it."
Hu Jiu looked around and found that he could see a white light in all directions, which seemed to be some kind of moving Ghost Domain that happened to be passing by this place.
The Red Moon in the sky gradually disappeared, replaced by a bright, clear blue sky.
"Look over there!" Du Zhong pointed in a direction.
Hu Jiu turned his head and saw what appeared to be a dividing line in the distant sky.
On one side of the dividing line is the bright sunshine of spring, while on the other side is a gloomy, ominous red.
Hu Jiu grabbed Du Zhong and was about to teleport there, but found that the dividing line seemed both close at hand and far away, seemingly within reach yet unattainable.
"It seems we've been swept into a massive Ghost Domain realm," Du Zhong calmly assessed the situation.
Hu Jiu dared not let his guard down and immediately observed the surrounding environment.
This place seems to be a primeval forest, untouched by human hands. The unknown trees grow very tall, but there is not a sound around, not even the wind or the chirping of insects; it is eerily quiet.
"A place where even the radiance of the Red Moon cannot penetrate is definitely not simple. Be careful," Du Zhong warned.
Hu Jiu nodded, and a ball of dark, chaotic Supernatural condensed in his palm, which he then smashed onto the ground.
Countless vicious curses spread rapidly in all directions from him.
"Holy crap, did you have to be so reckless?" Du Zhong was startled.
Hu Jiu sneered. Did they really think he was a pushover? He was one of the main culprits responsible for the destruction of the world!
His Supernatural were rapidly transforming the environment; the once bright and sunny primeval forest instantly became gloomy and terrifying, as if countless demons and monsters were lurking within.
The trees in the forest were affected; their bark sprouted hideous human faces, their branches twisted, and their twigs resembled menacing Ghost Hands.
Soon, a rotting corpse dressed in a burial shroud emerged from the roots of each tree, as if the people buried in the trees had become walking corpses. They stared with empty, lifeless eyes at Hu Jiu and Du Zhong.
However, the next second, these zombies were corrupted by Hu Jiu's Supernatural and collapsed, seemingly turning into real corpses.
"These things crawling out from under the tree roots are all Fierce Ghosts!" Hu Jiu said calmly.
Du Zhong's tone also became serious; his observations were more detailed than Hu Jiu's.
"Each corpse contained at least one Fierce Ghost. The burial clothes they wore, the land and trees, and the sunlight worked together to effectively suppress the resurgence of these Fierce Ghost."
"This place looks more like a graveyard where Fierce Ghosts are buried; the signs of human intervention are very obvious."
Hu Jiu: "You mean there might be living people here? Have you ever encountered living people in the Ghost World?"
Du Zhong: "Of course there are living people in the Ghost World. I've met them before, but most of them have the same personality as you. They're very difficult to approach, and they'll start fighting and killing each other at the slightest disagreement. They're extremely violent."
Hearing this, Hu Jiu rolled his eyes. "Don't think I didn't realize you were talking about me. Anyone who can survive in an environment like the Ghost World would be long gone if they weren't ruthless."
Du Zhong said, "You've disrupted the balance here. Who knows what will happen later? Anyone who can set up such an area in the Ghost World is probably not someone to be trifled with."
Hu Jiu: "Let's provoke them first, and if we can't handle it, we'll run away. Besides, we didn't start it; they just walked right into our path."
