Virtual Reality (VR) is a high-tech technology that has emerged in recent years, also known as spiritual technology or artificial environment. Virtual reality is the use of computer simulation to generate a three-dimensional virtual world, providing users with visual, auditory, tactile and other senses of simulation, so that users can observe things in three-dimensional space in a timely and unlimited manner as if they were in the scene.

Multi-Sensory

The so-called multi-perception refers to the auditory perception, force perception, tactile perception, motor perception, and even taste perception and olfactory perception in addition to the visual perception possessed by general computer technology. The ideal virtual reality technology should have all the perceptual functions that all humans have.

Immersion

Also known as presence, it refers to the degree to which the user feels real as the protagonist in a simulated environment. The ideal simulation environment should make it difficult for the user to distinguish between the real and the fake, so that the user can immerse himself in a computer-created three-dimensional virtual environment where everything looks real, sounds real, moves real, and even smells and tastes real, just like what it feels like in the real world.

Interactivity

Refers to the degree to which the user is operable with the objects in the simulated environment and the degree of naturalness (including real-time) that receives feedback from the environment. For example, the user can directly grasp a virtual object in the simulated environment with his hand, and the hand can feel the weight of the object, and the object in the field of vision can also move immediately with the movement of the hand.

Imagination

It is emphasized that virtual reality technology should have a broad imaginable space and broaden the scope of human cognition, not only to reproduce the real environment, but also to imagine the environment that objectively does not exist or even impossible.

Since the first letter of the English word for immersion, interactivity, and conception is all I, these three characteristics are often collectively referred to as the 3I characteristics. Generally speaking, a complete virtual reality system is composed of a virtual environment, a virtual environment processor with a high-performance computer as the core, a vision system with a head-mounted display as the core, an auditory system with speech recognition, sound synthesis and sound localization as the core, a body orientation and posture tracking device with an orientation tracker, a data glove and a data suit as the main body, as well as functional units such as taste, smell, touch and force feedback systems.

The next day.

After Qingyi finished washing and dressing neatly, he looked in the mirror again, and then picked up his briefcase and went to work. Today is his first day at work since he took sick leave.

The company he works for is "Little Bee Express", and the name may sound related to children, but it is actually a food delivery company, responsible for bridging the gap between restaurants and customers. Qingyi worked here as a marketing executive after graduating from university, and his job was quite smooth, if you didn't count the fact that he was shot by a former colleague a week ago.

Winters in Cambridge are getting colder. Pedestrians on the street wore overcoats and scarves, like clumsy brown bears.

Why don't you go to McDonald's and buy a hot drink? Qingyi thought so, stepped on the pedal vigorously in the cold wind, and came to the downstairs of the company. He locked his bike, went up to the second floor, and as soon as he appeared at the door, he shouted, "Hey, guys! I am back! ”

Everyone in the office was stunned for a moment, and then immediately boiled: "Oh, Zhang, it's so good to see you!" "Does it still hurt?" "How does it feel to be hit? Did you pee your pants at the time? ”

I finally know why Lucy was the representative of the patient at that time, and asked you to visit me, and you didn't tear down the roof of my house?! Qingyi was so easy to deal with everyone's gossip.

"You don't seem to have slept well, do you?" Edward pointed to his eyes.

Qingyi subconsciously touched the bags under his eyes, and said with a smile: "I was so excited last night, I couldn't sleep with joy at the thought of seeing everyone." ”

Lucy got up in disgust: "Zhang, your sentence is obviously a lie!" Looks like you're going to grow into a man too, hehe. I'll make you a cup of coffee. ”

"Thank you." Qingyi smiled awkwardly, and then walked to his desk. He stroked the back of the swivel chair, looked at the special phone, and sighed for a while: I haven't seen them for a week, and I am actually a little unfamiliar with them.

Edward wore new clothes, but still a plaid shirt; He smeared mud in his hair, a bit like Elvis. And Lucy is still wearing a monotonous and old-fashioned sweater, and people who don't know will think that she is a well-maintained aunt. And Todd is still very wrong with Qingyi, even if Qingyi came back, he didn't come up to say hello, but put his feet on the desk to play PSP.

"Hey, it's cold, it's better to wear more clothes." Qingyi said to Todd, who was wearing only a jacket.

Todd glared: "I want you to care!" Qingyi smiled instead.

Today's work is as plain as water, but for Qingyi, life is finally back on track. For some reason, he had a faint sense of security in the company, which made him not afraid of some illusion that suddenly flashed in front of him. At lunchtime, Edward took the initiative to pack one for Qingyi, and the two talked about the recent market situation and marketing environment, and there was nothing special besides.

————————————————————————————————————

At the end of the day's work, Qingyi went home and couldn't wait to start the game.

After appearing in the room, Qingyi didn't dare to move, first felt the soul wavelength transmitted in the air, and after feeling calm, he dared to walk out of the room. Two extremely intense wavelengths were coming from two locations, the Tree of Withered and the Pool of Blood. So he walked out of the City Lord's Mansion and came to the blood pool first.

A misty gray mist escaped from the gate of the blood pool, and as soon as you stepped inside, the mist was so thick that you couldn't see your fingers. These mist are essentially dead qi rich in dark elements, which is equivalent to man-made dead qi clouds, which have a great nourishing effect on necromantic creatures. In addition to the generals present, there was probably Grande.

A voice came from the mist: "Hey, the apprentice is here?" ”

"yes, I'm not here to visit you, teacher." Qingyi opened the [Soul Eye] so that he would not step into the pool of blood with one foot.

The other party only exposed his naked upper body to the surface of the water (his clothes were scattered on the side), and sat against the wall of the pool, his long hair rising and falling in the blood like aquatic plants; They rested their arms on the floor with a refreshed expression; His topaz-like body is muscular and powerful, with smooth and eye-catching muscles. The blood turned into wisps of blood smoke around him, giving people the illusion that he was soaking in a hot spring. Blood is a great tonic for zombies, not to mention the effect of blood pools.

"Little, little white!" And Grande sat on the edge of the blood pool, waving happily to Qingyi. His feet were soaked in blood, and he kicked small splashes. In the gray mist, the coral beads were kicked up by the young man's white and tender toes, and the music of tinkling and ding dong was struck on the water surface, which was luxurious and chaotic.

"Come on, come on, come and sit." The general greeted.

"No, I'm going to find Mr. Dever." Qingyi said goodbye leisurely, immediately walked back, and then silently recited "three, two, one" in his heart. Before he could pronounce the word "one", the general shouted "Slow", jumped out of the blood, and his clothes flew up spiritually, and he was automatically dressed neatly.

"What are you looking for him?" The general had a straight face, and his voice was faint.

Just know you're going to take the bait! Qingyi smiled secretly, but quickened his pace, and said seriously: "Ask him for some trivial things." ”

"Ah, don't you go to find the broken gong now? Boy dare to hear! The general was in a hurry, grabbed Grande with his hand, and strode after him.

The blood pool was not far from the Wandering Soul Square, and Qingyi soon came to the center of the square. Under the Tree of Withering, the Grand Lich Dev Brie sits leaning against a tombstone. He is surrounded by dark elements and death, making it impossible to see his true face. The soul fire in the tree turned into a blue waterfall, which flowed down with a roar and fell on his head, and he absorbed it cleanly. Being tossed by him like this, there will definitely be fewer ghosts to recruit in the "City of Waiting" this month.

"Teacher Dever!" Awakening the gloomy Defu, Qingyi said to the generals who rushed over and stretched their faces: "Teacher generals! I'd like to talk to both of you. As the saying goes, 'the country has its laws, and the family has its own rules', and this is the territory of the students, and there is a daily work order. The student dared to ask the two teachers to make an appointment with the three chapters of the law, and not to do it again—not even to compete with soul power! What do you think? ”

The general tilted his head and showed a gesture of complete contempt: "Since the good apprentice has spoken, I will give you a face." ”

"Is your face worth anything?" Dever sneered.

"What a dog's mouth!" The minister's face cracked and exploded. He snapped his knuckles (making a thunderous rolling sound): "Don't be ashamed of your face, you brought it on yourself!" ”

"Looking for what? Looking for guilt? To face an idiot like you day and night is indeed to find guilt. Defer's skin turned purple all over his body, his lips were shattered and his gums were exposed, and his eyes lit up with blue soul fire, showing the terrifying posture of the Great Lich: "I knew I would meet such a strange thing as you, so I wouldn't have come to the 'gospel'." ”

Qingyi hurriedly stood between the two and stretched out his arms: "Calm down!" Fight again, I'm ...... I don't want this city anymore! You two...... Are you here to be a teacher, or are you a ...... Demolition team?! ”

Under the momentum of the two peak hero-level NPCs, Qingyi almost didn't kneel, and even spoke intermittently. He endured tremendous pressure and insisted: "All in all, no...... Do it again. If you want to be superior, you can only use academics and knowledge to compete......"

"The avenue is nameless, how can you tell the true meaning in words?"

As soon as the general retorted, Defu laughed: "It turns out that you are also inferior to me!" ”

"your 180 ancestors! Although I am a zombie, it is a trivial matter to learn from those bulls' noses and sit and talk about the Tao! Come on, who's afraid of whom?! The general put away his coercion and shouted.

"A barbarian is a barbarian, and there is nothing but howling and posturing." Defu also slowly regained his momentum, changed back to his human form, and smiled suspiciously: "What do you want to talk about?" ”

"Whatever you want!" The generals raised the sleeves of their robes, and there was a great taste of "soldiers coming to block, water coming to cover the earth".

As soon as Qingyi saw that the situation had improved, he sat on the Shadow Throne and prepared to listen to the lecture. He dragged Grande to the side—the boy was hungry and was about to dig up some corpses in the small cemetery.

"Well, let's start with the formation of the universe. The predecessor of the universe was Endless Chaos, and you can accept that. ”

"Why not? The "Yellow Court Inner Scene Sutra" is clearly written on white paper and black letters, the clear air rises to the sky, and the turbid gas sinks to the ground. The general snorted.

"And in the chaos there are elements such as light, darkness, ice, wind, fire, water, thunder, earth, etc., they-"

"Wait! What mess? There are only five elements of gossip between heaven and earth, where does the bird element come from? ”

Devo shrugged his shoulders at Qingyi, who was listening: "Look, there's no way to communicate." ”

Qingyi couldn't help but smile bitterly. From the very beginning, there has been a huge gap between Chinese and Western cultures, which is caused by the different perceptions of nature by our ancestors.

Seeing that the apprentice smiled, the general's face turned red and shouted: "Then let's not talk about this for now, let's talk about Taoism and magic." ”

"It's fine. In my dealings with you, I roughly understand that Taoism is used in accordance with the Five Elements and Bagua, and magic also needs elements to be activated. Not to mention chanting, even the Eastern Formation is much the same as the Western Magic Formation. Although Deffer sneered, his expression was much more solemn. He frowned and said, "It's just that there is one thing I don't understand, why is the beginning of Taoism generally 'Mrs. Laojun is as anxious as the law'?" Who is Taishang Laojun? The gods who created Taoism? ”

"Anyway, I haven't read this sentence, so it doesn't count."

"And it's too strange for a Taoist priest to use a sword as a spell casting prop, right?"

"Your wands are weird! In our 'Huaxia', only the Wu clan uses a staff to cast spells! ”

"Witches? Is it a witch? ”

"There are men and women in the witches, and not all of them are witches."

"The witch and the man?!"

Listening to the two chickens and ducks, Qingyi was overjoyed, but he didn't dare to laugh, so he covered his mouth. Grande rested his head on the armrest of the throne and fell into a deep sleep.

————————————————————————————————————

In the same night......

In an ordinary house in New Jersey, USA, a teenager with albinism is sitting on a chair, playing with a mouse and eating potato chips. His cheeks moved, but his eyes didn't move. The thick myopia lenses could not separate his cold and indifferent eyes. The screen shows a report of the Tyrant of Bones taking Orquila.

"If you don't have a 'chess player' to play against you, you'll be arrogant, June!"

The albinistic boy was in good spirits and smiled very brightly: "You know, the reason why I didn't do my best in the last game is to deceive you!" All kinds of methods that I have not used before, this time they will all be used on you, and you will be completely sunk! Is war fun? It's fun, of course, but only the winner can enjoy it! Since you want to start a war, I'm going to make you dare not do it again! ”
