Luo Kai walked to the window and gazed at the full moon and stars in the sky. He was certain that this place did not belong to the original Earth, but the universe, the environment, and the matter were all the same as Earth.
The only difference from Earth was that this place was abnormally rich in dark energy, or in other words, Yin energy.
Unfortunately, after leaving his body, Luo Kai lost the dark perception brought by the Sacred Blood Worm. He could not research, mobilize, or use it.
However, he had a deep understanding of the nature of dark energy.
Everything in the world was born from something, and something was born from nothing. If light energy was the product of material transformation, it belonged to "something".
Then dark energy belonged to "nothing", or the power of "nothingness".
Most of the things in the world could not be seen or touched. Everything that could be seen and felt came from this "nothingness" and was controlled by the dark energy of this "nothingness".
In other words, to a certain extent, what was nothingness determined what was real, and what could not be seen determined what could not be seen. This was the truth of the world.
This world was formed by the power of nothingness. Everything was constructed by dark energy.
The universe was constructed by the six major energies of time, space, light, darkness, elements, and chaos. Without any of these, it could not be considered a real world. Due to the lack of the other foundations of the world, this world did not really exist. However, the distinction between nothingness and reality was meaningless.
In the macroscopic world, when one looked at computer games, one would naturally think that they did not exist and were just computer programs.
In the microscopic world, if an individual could enter a computer game, then the computer game was real.
In short, Luo Kai might have really entered a virtual world. Humans could use technology to create a game world and store it in a hard drive. Naturally, there would be higher-level existences that could simulate a world based on Earth.
However, the simulation was not perfect. Due to the lack of other energies, there might not be any light energy here. The flow of time was also different from the outside world. It was like a dream.
Dong … Dong … Dong.
A deep sound of a wooden fish interrupted his thoughts.
The sound of the wooden fish contained a mysterious rhythm. Luo Kai's soul was slightly agitated and became unstable. The rhythm of the wooden fish seemed to be targeted at souls.
Curious, he gently pushed open the door and walked towards the direction of the sound.
Not long after, they arrived at a small courtyard in the back hall. An old woman sat cross-legged in the main hall of the courtyard. Her white hair and slightly withered body could only be seen. The old woman was muttering to herself as she tapped the wooden fish in her hand rhythmically.
Luo Kai quietly retreated. At this moment, the old woman turned her head and looked at him with bright eyes.
"Young man, don't you think it's impolite to barge into the master's house?"
Although the old woman looked old, her face was very delicate. There were no wrinkles on her face. If it wasn't for her white hair and slightly thin figure, people would think that she was a young girl.
Luo Kai lowered his head slightly. "I'm really sorry. I didn't do it on purpose. I heard the sound of Old Madam's wooden fish and couldn't help but come over."
The old woman stared at Luo Kai for a while. Suddenly, a smile appeared on her face. "Not bad, young man. How did you find my house?"
"It's just a coincidence. I'm really sorry to disturb Old Madam's cultivation."
The old woman nodded and smiled. "Very good. What do you think of my house?"
Luo Kai looked around. The dark night couldn't block his vision at all. The whole mountain and river entered his mind. He praised, "This place is very beautiful. It's a good place to live in seclusion."
The old woman was even more satisfied. She continued, "Then are you interested in living here?"
Luo Kai shook his head and said, "Thank you for your kindness, Old Madam. I have something important to do. I have to leave now."
Before he finished speaking, his expression suddenly changed. Although he didn't have any sense of smell, he could feel any subtle energy fluctuations. At this moment, the space around him suddenly became unstable.
He turned his head and looked outside the courtyard. On the walls around him, ripples appeared in the void. One after another, strange creatures appeared.
They had a monstrous ape-like face. Rows of fine teeth were exposed outside of their mouths. Their lower limbs were tightly grasping the walls. Pairs of eyes that only had the whites of their eyes left stared at him.
These things looked like dark creatures. However, the dark creatures in the outside world were far inferior to this world built of dark energy. They held steel forks in their hands. Bone spurs grew out of their backs. Their hair flickered with green flames. One of their noses pointed to the sky and the other pointed to the ground. They were deformed and ferocious. They were like the legendary Yaksha evil spirits!
The old woman sighed and said, "Young man, you really came at the wrong time. My house has been besieged by Yaksha these days."
The Yaksha evil spirits were neatly squatting on the walls. They didn't attack. They seemed to be waiting for something.
A slender figure ran into the small courtyard. When she saw Luo Kai, she first glared at him angrily. Obviously, she was angry that he didn't listen to her and barged in. Then, she anxiously said to the old woman, "Grandma, these things are coming again!"
The old woman waved her hand and said in a cold voice, "Don't be afraid. Kill as many as come!"
She slowly stood up and shouted into the night, "Zhu 'er, since you are here, show yourself."
"Hehe … Big Sister is so awesome!
I am always discovered by you. I am so bored. Big Sister, come and play with me, okay? "
A voice that sounded like a young girl's rang out. The voice was pleasant and crisp. However, in the pitch-black night, it sounded abnormally sinister.
Luo Kai looked at a big tree in the corner. On one of the branches of the big tree stood a little girl with a ponytail. The little girl was wearing bright red clothes. She had bright eyes and white teeth. Her smile was as beautiful as a flower. Her big eyes were staring straight at him.
"Eh, there is a big brother today. Big Brother, come and play games with me." The little girl grinned at him.
Luo Kai frowned. The little girl was clearly standing there, but he couldn't sense her at all. She was obviously not ordinary.
By now, as long as he wanted to, he could see everything in the world. Nothing could escape his Eye of the Soul. However, the things in this world couldn't be judged by common sense.
"Little Sister, you have surrounded my Peach Blossom Garden for several days. On account of our past relationship, how about you let this young man and Xiao Ling go?"
The little girl chuckled and said, "Hehe, Big Sister, don't worry. This big brother has such a strong fiendish aura. After he dies, he will definitely become a top-grade evil spirit. I can't beat him!"
The old woman looked at Luo Kai with some doubts. She muttered to herself for a while and said, "Little Sister, you have already become a Void Yaksha. You should have recovered your memories from when you were alive. You should know that the one who killed you was Ghost Mother of Mount Li, not me."
The little girl stopped smiling. Her little face turned gloomy as if she was thinking about the old woman's words.
After a while, she suddenly smiled and said to Luo Kai, "Big Brother, do you think I am pretty?"
Luo Kai looked at her obediently and saw that her figure was slowly growing. In a short while, she had turned into a delicate and charming young girl. The blood-red clothes on her body had also changed into a set of light blue Han Chinese clothes. She was elegant and graceful, and her beautiful face was slightly red. She looked shy and timid.
Just as Luo Kai seemed to be in a daze, the young girl suddenly smiled sinisterly. Her delicate face began to turn green and quickly rotted. Sticky yellow liquid flowed out from her sunken eye sockets. Her entire body was instantly covered in corpse fluid. A strong stench assailed his nose. The beautiful young girl had turned into a pink skeleton in an instant.
At that moment, the skeleton opened its mouth and spat out a black mist at him.
Luo Kai didn't move. It was as if he had fallen into a maze and was about to be hit by the black fog.
At this moment, a slender figure flashed to his side. With a light wave of the wooden sword in her hand, a white light flashed and dispersed the black fog.
The figure was the young girl who had received him in front. After dispersing the black fog, she angrily said to Luo Kai, "Humph, I told you not to go out. Why are you so disobedient!"
Luo Kai seemed to come back to his senses. He smiled at her and then looked at the little girl indifferently. He didn't look angry because he had been plotted against just now.
The little girl returned to her original appearance. She stroked her little chin and said in confusion, "Little brother, I just wanted to test you. Oh, you're so strange. Normally, when humans see me, they either like me to death or are scared to death. But why are you … Why aren't you scared or like me?"
The old woman frowned and said, "Little sister, my peach blossom garden is built with thousand year old peach trees. Ten thousand ghosts will avoid them. It is impossible for these low-level yakshas to break in. If you have any other evil techniques, just use them."
The little girl giggled and said, "Big Sister is so smart. This time, I got some corpse fluid from the Undead King. But I grew up in the peach blossom garden. I really can't bear to destroy it."
The old woman's expression changed. She turned to Luo Kai and said, "Young man, I can see that you are also a cultivator. Those on the wall are earth yakshas. My little sister has cultivated into a sky yaksha. Earth yakshas have infinite strength. Sky yakshas are shapeless and intangible. It is difficult for humans to fight against them. I will block them. You and Xiao Ling should leave."
Luo Kai didn't reply to her. Instead, he silently observed the things and things in this world from the perspective of the fourth dimension. Similarly, in the perspective of the fourth dimension, this world was also presented as data. Everything, things, and even living things were built by codes or programs. If one could find and modify the original codes, they could change and control this world.
