In the middle of the night, the cold wind blew. Dark clouds formed by pure dark energy blocked the already bleak moonlight, making the silent mountain even darker.
Luo Kai floated to the bottom of the mountain. There was an endless deep mountain stream, or more accurately, an abyss.
Humans designed astronomical telescopes that could use the naked eye to spy on the secrets of the universe. However, human eyes could not penetrate the ground, so some places that could penetrate the ground were named abyss.
Compared to the visible starry sky, people had a much more limited understanding of the underground world. In all kinds of legends, if heaven was in the starry sky, then hell was underground.
Now, Luo Kai already understood that the so-called Gate of Abyss should be a stable anti-space entrance. The visible universe that people were in was physical, called "reality". It was the carrier of the virtual universe, which was the virtual space.
In other words, the physical space was the medium, and the virtual space was the data.
Of course, space expanded infinitely, time did not stagnate, and things developed eternally. Everything was infinite. Perhaps the physical space was just the data of another world.
The Gate of Abyss was not the concept of a door in the conventional understanding. It was a long and narrow crack between the virtual world and the real world. The small world he was in now was the gray area between the crack, and it was the intersection of the two worlds.
To enter the virtual world of the underworld, it was like using a USB drive to upload data. Only data could be uploaded, which meant that only the soul or other microscopic medium could enter.
This was the rule, and also an established basic program. However, any program that ran for a long time would always have bugs, and it would also be interfered with by other small programs.
Now, there was a big loophole in this program. Not only could the creatures of the underworld enter the physical world, but the existence of the physical world could also enter the underworld with their bodies.
Luo Kai stopped in front of the mountain stream and looked at the peach wood sword in his hand. As the saying goes, when things reach an extreme, they will move in the opposite direction. When the dark energy condensed and compressed, the light energy would appear. This peach wood sword was a product of extreme Yin transforming into extreme Yang. It was an extreme Yang weapon.
The Taoist technique recorded on the handkerchief that Xiao Ling gave was not ordinary. It was called the Da Luo Spell.
The handkerchief was densely packed with strange symbols. If it was before, Luo Kai might not have been able to understand it. However, with the four-dimensional cognition, anything in the three-dimensional world could be summarized with a program.
To put it simply, these symbols were codes that formed a small program according to a certain pattern.
Don't underestimate this small program. In the programmed world, it was a cleaning program or an antivirus program that could remove other programs and remnants.
In the real world, the effect was obliteration, or rather, destruction.
"Daluo" was a supreme existence in Daoism. It was a powerful spell that could shake the rules of the mind. In other words, it was a method of program invasion.
This could be the real magic of the gods. Unfortunately, the spell on the handkerchief was obviously incomplete, or rather, only a small part of it. This kind of magic should have a complete set of cultivation and casting system, just like how a programmer would learn, practice, and finally create.
Luo Kai took one last look at the stars in the sky, and then quickly fell into the mountain stream.
He knew that once he entered the Dark World of the Underworld, the energy of the stars would no longer be of any help. Other than a powerful soul, he would be useless.
Now, as their understanding of the four-dimensional world deepened, it was obvious that there was another level of existence above this world. They were gods, immortals, Buddhas, and the Creator. They were existences that transcended the three-dimensional universe. The stars and the universe were just toys in their hands. Even the powerful Evil God could only barely touch them.
After falling for an hour, there was still no end to the mountain stream. Other than the increasing density of the dark energy, there were no abnormal changes.
The soul was of the Yin attribute, and the body was of the Yang attribute. It was very comfortable for the soul to wander in the dark energy. He even felt a little sleepy.
After an unknown period of time, Luo Kai's expression suddenly changed. He stopped falling and arrived at a gourd-shaped cave.
Numerous black shadows climbed up the walls of the cave and quietly surrounded them.
Without the Saint Blood Worm, Luo Kai had lost his ability to sense the darkness. He could only slightly concentrate and strengthen his ability to see through the darkness. He saw the faces of the shadows clearly. They were wild cats that had rotted to the point where only their skin and bones were left.
The fur of these wild cats had almost completely rotted, revealing their blood-red skin and pale white bones. Their sharp claws were tightly clasped on the walls. Their eyes were filled with a bloodthirsty glow, and they were constantly growling.
Luo Kai looked into the depths of the cave and muttered to himself. It was a good opportunity to test the power of the peach wood sword on these dark creatures.
At this moment, a few of the corpsecats seemed to have received some kind of order. They growled and rushed over.
Luo Kai waved his hand, and the peach wood sword faintly lit up with spots of white light. The sword light flickered like a white rainbow, illuminating the pitch-black underground cave. The corpsecats in front of him were instantly cut in half.
It was as if a hornet's nest had been poked open. All kinds of mournful howls shook the entire cave. The densely packed shadows on the cliff attacked. Not only were there humanoid ghouls, there were also all kinds of rotting animals.
They still retained their corporeal bodies, and their consciousness had not dissipated. However, they were indeed dead creatures. They were a kind of strange life form that existed between life and death. They were also a unique product of the chaotic zone between the two realms of Yin and Yang.
Whether it was erasing their consciousness or destroying their bodies, or even doing both, it was impossible to truly kill them. Their consciousness would reassemble after it dissipated, and their bodies would reform after it was destroyed. Strictly speaking, they were an undying existence.
This made Luo Kai very curious. He slowed down his killing speed and carefully studied it.
Regardless of whether it was the body or consciousness, they were all constructed from energy. He might have entered an independent space where everything was in an independent cycle and was not affected by the law of conservation of energy.
Gradually, he descended to the bottom of the cave. When he saw the scene before him, Luo Kai couldn't help but be stunned.
In front of him was actually a slightly dilapidated courtyard. Dense Yin Qi surged above the courtyard, and the surroundings were full of withered vines. It was extremely desolate and bleak.
Three blood-red words were very conspicuous on the gate: "Lishan Courtyard".
Just as Luo Kai was greatly astonished, a bright red lantern constantly flashed in the courtyard. A clear and melodious voice rang out: "Welcome, esteemed guest, to Lishan Courtyard."
At the same time, flickering candlelight continuously lit up the courtyard. Shadows appeared one after another, and a woman dressed in ancient Han clothing appeared at the gate.
The woman was very beautiful, but her body was not corporeal. It was like a shadow. Like Luo Kai, she was also a soul.
"Hmph, stinking brat, come in if you have the ability!"
On one of the walls of the courtyard, the little girl Yaksha evil spirit appeared. Her body was clearly much thinner, and her pair of large eyes were filled with hatred.
Luo Kai was even more astonished. He was sure that he had directly erased this Yaksha evil spirit. It was that kind of disintegration on the level of particles. But now, she was actually alive again?
The woman at the gate had a cold expression. She sternly shouted at the little girl: "Zhu 'er, you didn't listen to your mother's words and secretly led the ghosts to seek revenge. You have already committed a great crime. Why haven't you returned yet?"
The little girl seemed to be somewhat afraid of her. She glared hatefully at Luo Kai, and her body slowly disappeared.
