Wu Lang, who returned to his room, walked to the bathroom, took a shower, picked up the suitcase at the head of the bed, put it on the carpet, opened it, lifted the clothes on the upper layer, took out the small iron box inside, turned the small disc in the middle, and entered the password.

After an extremely slight but unusually crisp sound, the lid of the small tin box automatically stretched upward.

The No. 05 envelope inside was still a yellow cowhide envelope, and in the middle of the seal, there was a red fingerprint imprint, and then, Wu Lang used the little finger of his left hand to aim at the red fingerprint on the No. 05 envelope and pressed it deeply......

The red fingerprints on the yellow cowhide envelope then slowly spread, and gradually dyed the entire yellow cowhide envelope into a red color.

Suddenly, the crimson envelope turned into a red waterline, and it quickly sank into Wu Lang's little finger and the gap between his fingernails.

Wu Lang, who lowered his head, looked at the scene in front of him with no surprise, held his left hand, stretched, and repeated it a few times, feeling that there was nothing unusual, and then slowly opened the palm-sized white letterhead in his hand.

The palm-sized white letterhead, automatically without wind, slowly suspended in front of Wu Lang's eyes, and then, the letterhead disappeared, leaving only hundreds of golden characters in the air......

"There are seven mysteries in the world: one is Xuan, two is Lian, three is Tian, four is line, five is Nian, six is Yuan, and seven is extreme. Pole Yuan, Yuan Principal Thought, Nian Super Line, Line Boundless, Heaven Boundless, Xuandian ......"

"There is a mixture of forms, and it is born from nature. It has no present, its past has no past, its height has no cover, its low has no load, its big has no outside, its small has no inside, there is nothing outside, there is no one inside, there is no self near it, and there is no other ...... its distance."

Wu Lang stared blankly at the big golden characters in the void, and thought quickly in his mind: If it is interpreted according to its literal meaning, the universe is first chaotic, and the universe cannot be divided by mechanical theory, that is to say, the universe is in a holographic state, and space and time, macrocosm and microcosm, matter and spirit are all artificially divided. The dimension of the universe cannot be limited to the realm of matter, and we cannot only look at the world from the point of view of matter. First of all, people must draw a clear line between matter and antimatter, and photons, neutrinos, and antiparticles cannot be reduced to matter, because they transcend the properties of matter. It is necessary to use the philosophical point of view to guide the division between matter and antimatter, without the means of science and technology, with the perception of ordinary people, everything that can be seen, heard, and touched belongs to matter, and beyond this is immaterial, applied to physics, this boundary is light.

Light is the fourth dimension of the universe, and the first dimension of the universe is the point (i.e., "Xuan"). The second dimension is the line (i.e., "connection"), which includes curves, lines, and line segments. The third dimension is space (i.e., "heaven"), some people regard the plane as the third or second dimension, but it is actually a subjective cognition, there is no plane in nature, and the surface belongs to a sphere or a spherical thing. There is the existence of light in nature, and there is the yin and yang of heaven and earth.

Time is derived from light, so time is not included in the cosmic dimension. Those things that cannot be seen, heard, or touched, but are real, can be classified as antimatter, but can be divided into thoughts and spirits. The fifth-dimensional mind (i.e., "mind") and the sixth-dimensional spirit (i.e., "yuan", the primordial essence and the primordial spirit) of the universe also exist everywhere at all times. The meaning of the mind is not limited to the mind of the living body, but also includes the central axis of the movement of the stars and particles, and the origin of all things is the primordial essence and the original spirit, which derives all things in various forms, and finally returns to their origin.

In the chaotic universe, there is another dimension that is indispensable, that is, the "nothingness" in it, which is the foundation of the existence of all things. All things are hidden and looming, appearing and appearing, appearing with form or desire, disappearing and resting without a trace when hidden. This "void" should be nothingness, which means hidden, but it is different from the vacuum of space.

The hundreds of golden characters floating in the air gradually faded and disappeared. Wu Lang slowly got up from the carpet, walked to the balcony, sat on the sofa, drank the Scottish "Watergar" in his hand, took a puff of cigarette, and then looked up at the silent night sky......

If we look at the problem of the cosmic dimension, the "line" is light. In the void, there is the primordial essence and the primordial spirit, and the mind is dominated by the mind, and the activity of the mind can exceed the speed of light, and the spread of light is boundless (time also has this characteristic), the space is bound by various lines, and the points are scattered in the void like stars. The seven dimensions exist in the universe in a holographic state, which is irreplaceable and cannot be surpassed.

The vastness of space contains "poles", the atmosphere and water contain "poles", the compact core of the earth contains "poles", the mind contains "poles", and the mysterious cosmic black hole contains "poles". Black holes are the "elements" of the universe, and the "elements" contain poles, otherwise they cannot incarnate all things. Without poles, there would be no stillness, and without poles, other dimensions would not be transformed. "There is no infinite thought, there is no boundary, the meta pole is limited, the thought can be clear, and the thinker is wired. Three Xuan Fu world, the world is a little line, the line is pure Xuan, so the world is a point. The world that can be seen in the world belongs to the category of "heaven", supplemented by the three dimensions of primordial essence, spirit, mind, and light, so that there is a colorful world. All this is complemented by the "pole". Light is a pure dimension, and it is intertwined with nothingness.

Bursts of smoke drifted in the night sky, and then were blown away by the sea breeze, Wu Lang still looked up at the endless night sky stupidly, and the shock in his eyes was undoubtedly revealed: How did the ancients know and divide these dimensions? Nowadays, scientists speculate that there are 11 dimensions of space in the universe, in addition to length, width and height, there is also a four-dimensional space being studied, and the other 7 dimensions are hidden, just like human beings know the existence of ultrasonic and infrared rays, but they can't hear or see, and what can't be perceived is not necessarily non-existent, which is similar to the discussion of the ancients!

"The things that have happened and encountered me during this time are bizarre enough to be difficult to describe. The universe is so big that human beings can't imagine or predict how many things will there be? Who can explore them all?" Wu Lang muttered softly to himself.

In the depths of the sea, where the water and the sky meet, a piece of fish belly white gradually appeared, and the sky slowly brightened, and the shining moon and bright stars were gone. An orange ribbon appeared in the sky, thin and long, like a colorful river between the sky and water, and slowly, the clouds in the sky also burned, like a fiery red kapok......

"When" ...... "dang" ...... "dang......

A knock on the door interrupted Wu Lang's thoughts, and then, he turned around and went back to the room, quickly packed his suitcase, put on his clothes, and opened the door.

"I don't lock the door in my room, why are you a big man locking the door?" Yin Yuting looked at Wu Lang with disgust.

"I'm afraid that you will sneak into my bed in the middle of the night and plot against me, so I'd better be careful, so as not to lose my body, and then I will regret it, and it will be too late to regret it!" Wu Lang looked at her seriously. Said.

"Virtue, walk, run. Yin Yuting gave him a blank look, turned around and went downstairs.

The two of them ran around in the morning and returned to the villa, and saw that Yin Fatzi had already bought breakfast, Wu Lang immediately sat on the chair, ate some briefly, and hurriedly drove out and went to the hospital.

After arriving at the outpatient building, Wu Lang took an inspection report and walked towards the office of Section Chief Niu, but there was no one.

"Wu Lang, Section Chief Niu went to the inpatient building early in the morning and said that you can go there to find her when you come. An innocent little nurse ran over and looked at Wu Lang directly.

"Okay, Nurse Liu, thank you. Wu Lang nodded and smiled.

"Do you have time after work in the evening? I'll invite you to dinner. Nurse Liu looked at Wu Lang expectantly.

"I'm sorry, Nurse Liu, I have to work overtime these days, it may be very late, I just graduated and went to our hospital for an internship, I don't know anything, I have to seize all the time to learn more with my seniors, so that it is convenient to find a job in the future, now the price is so high, there is no stable source of income, there is no way to survive." Another day, I'll invite you another day, okay?" Wu Lang looked at her and said with a smile.

"Alright then, you get busy first, I'll go. Nurse Liu looked at Wu Lang with a slightly disappointed expression, nodded, and turned to leave.

Wu Lang looked at her distant back, shook his head and smiled, turned around and walked out of the outpatient building quickly, and walked in the direction of the inpatient building.
