The world we live in is seen as an interface, a uniquely closed state of existence. To live or to die, that's a question.

For thousands of years, human beings have been working hard to break through the boundaries of this plane. Or Qu Yuan's nine questions, or the construction of the Hanging Garden, or the soul meditation of Sakyamuni, or the self-cultivation of immortals and demons......

Humanity as a whole has really taken this step, and it is the development of quantum mechanics that has broken the interface ceiling. People have gone from observing the fluctuation and particle duality of photoions to discovering the quantization of energy. Humans have discovered that quantum, as a physical concept, is a state of being, not existence itself.

In the microcosm, space, time, matter, and energy are all discontinuous, with the smallest unit quantum. Perhaps insignificant in the macrocosm. If the universe Chinese is not equal, the lower civilization is a stage and a running program in the operation of the higher civilization. Then we in the lower civilizations have weapons against the higher civilizations.

Relying on the quantum coefficient of force and density, and the strength coding, human beings have developed energy warships suitable for interstellar navigation. A language that matches the energy has been discovered - a magical language system. Humanity relies on this power to march into the universe, to fight against the darkness of the void, and to defend its homeland.

When we are still struggling with this kind of problem in the microcosm:

1. Q: Is there a sound in the universe?

Answer: According to the laws of physics, sound travels through the air in the form of waves. For example, when we speak, the vibrations of the vocal cords compress the air around us. The compressed air makes the surrounding air move and carries sound waves. Eventually, this compressed air reaches the listener's ear, and the brain interprets this activity as sound.

If this compression is high-frequency and fast-moving, the signal received by the ear is interpreted by the brain as a whistle or a scream. If they have a lower frequency and move slower, the brain interprets it as a drum, rumble, or muffled sound. Without anything that can be compressed, sound waves cannot be propagated.

There is no "medium" in the vacuum of space to transmit sound waves. It is possible that sound waves can pass through and compress clouds of gas and dust, but we cannot hear this sound. This sound will be too low or too high for our ears to perceive.

2. Q: So is space vacuum?

A: Although space is very "empty", infinitely close to a vacuum. But it is not an absolute vacuum, and space is filled with countless particles of all kinds. In near-Earth space, there are less than half a proton per cubic meter of space. Jumping out of the solar system, in the planetary system, in the nebula, various particles are compressed, more dense and can transmit sound.

3. Q: How can we hear sounds in space?

A: Sounds in space are inaudible beyond human hearing, but can be measured into sounds that we can hear. Through the technical means of radio frequency conversion, we can hear the lightning on Jupiter and the ebb tide of Neptune.

Hankai Ship Mound leaves a new surprise for interstellar physicists.

As Qin Hao escaped in the space-time tunnel, the green pattern joined the battle, and the black-patterned cracked leaves sprinkled seeds, breaking through time and space from time to time to attack the battleship, Copperfield retreated to the edge of the battleship to defend with a cold ice pointed pyramid.

Qin Hao ran out of the cave, the black-green pattern trembled violently, and he gave up attacking Tiemu and Minas. hovered and rushed towards Qin Hao. Qin Hao stared at the flying patterns, thought of the power of the space-time tunnel, stretched out his hands to seal, and recited the "Holy Light Punishment and Revenge Decision" in his mouth and quickly retreated to the cave. The divine brilliance enveloped the whole body, and the intricate ornaments of golden light were thrown and swirled on the body. The black-green pattern is sandwiched left and right, and the black pattern slaps on the light cluster, making a clanging sound. The green pattern enveloped the brilliance and was pierced by the sword qi.

Seeing Qin Hao's body exuding holy light and sword qi, the iron wood in the edge area was bathed in a golden aura.

"Light quantum entanglement," Zhuge Nantian looked at Guangxun and opened his mouth wide.

"Echoes of the Light: Legion Thrust!" Zhegui ordered the sword body to circulate with the mysteries of holy light, the purple-red pattern spread, and the 5-meter-high sword qi wrapped the iron wood. Tiemu leaped forward with both hands in his hands, and the purple-red sword qi slashed at the black-green pattern body in the center.

The black-green pattern that attacked Qin Hao urgently returned to defense, and layers of green covered the black pattern, and the black pattern brush shook and trembled, turning from a whip into a sharp sword, facing the ironwood sword qi.

"Boom!" The starry sky tore a crack, and the dense particles in the crack erupted with a loud sound. Ironwood was shaken back sharply, and the glittering golden-red armor slammed into the huge starstone behind the flagship's side, and with a click, the starstone was shattered by Ironwood. Tiemu leaned forward, holding his sword in both hands, and stopped his body.

The black pattern on the opposite side was shaken away, and the body turned into a long strip, and the pattern flapped, twisted, and rolled wildly.

Qin Hao fled back to the cave, the holy light emitted from his body restrained. Sitting on the star stone, Qin Hao carefully thought about all the attack skills, in the Holy Light Crusader battleship, there was only this book "Holy Light Imperial Sword and Sword Refining Talk" that looked like an attack skill,

Qin Hao recalled the essence of this book. "Hey! If you want to forge your own weapons, you must first have weapons. Qin Hao flipped over his upper and lower bodies, and there was nothing that could be called a weapon. Borrowing it from the opposing fleet, the distance is too far, enough for the black pattern to hit dozens of times, and it will be troublesome to avoid the green pattern capture, and be imprisoned in the space-time tunnel.

Qin Hao rubbed his hands together and looked at the other side.

Brother Tiemu straightened his clothes and rushed back again, and the great sword of Zhegui Ling was wrapped in purple-red light, and he slashed at the black-green pattern and launched an attack. Uncle Minas held the Fang Tian Battle Halberd in both hands, exuding holy light and battle qi all over his body, assisting in the defense.

The black and green patterns are around, the green patterns resist, and the black patterns attack.

Qin Hao took out the red cross in his pocket and looked at it, as a young man with atheism in the Chinese region, he was not very interested in the Holy Light Order. Qin Hao played with the cross, and the cross flashed with streamers. "Buzzing", two-dimensional three-dimensional, three-dimensional four-dimensional. Countless crystal swords flew out of the cross, at first they were points of light, but they slowly grew larger, turning into sesame seeds, into willow leaves, into daggers, and finally into three-foot long swords, surrounded by countless long swords, surrounding Qin Hao to form a sword formation.

Qin Hao stared at all this silently. Tie Mu, who was facing the black pattern attack, was surprised when he saw the flying sword surrounding Qin Hao. The green pattern strikes, blocked by Minas wielding his halberd.

Qin Hao stretched out his hand to touch the crystal sword beside him, the crystal sword turned and dodged, and Qin Hao laughed. Silently closed his eyes, thinking back to the record of "Talking about the Holy Light Imperial Sword and Sword Refining".

It turned out that these crystal swords were summoned to the three-dimensional space by the holy light, and each crystal sword contained a soul, and the noble soul crossed the wall of life and death to be inspired by faith..... The thing that hosts the soul on the wall is called a divine machine. Qin Hao touched the blood-red cross in his hand and muttered to himself. "It turns out that this is the Divine Machine, the Holy Light Divine Machine of the Crystal Sword Array."

"Crossing the interface barrier violates the laws of time and space. The flying sword that hosts the soul will be affected by the outside world and will continue to dissipate until the soul disappears. During the boarding period, it will continue to suck the life force around the divine machine. When the divine machine is threatened, it will passively protect the master, and the more souls it devours the host of the divine machine, the more powerful it will be......" Qin Hao muttered, and was frightened into a cold sweat at this wall-breaking thing, and then woke up in shock.

Qin Hao passed through the crack in the star stone, turned around and returned to the Holy Light Crusader battleship, and saw the "Holy Light Imperial Sword and Sword Refining Talk" on the bookshelf. Light up the garnet, read it carefully line by line, chewing on every word.

"I see, it can be like this". Qin Hao looked at it with a smile.

The Soul Crystal Sword is indeed a cross-border thing, using the soul state to achieve spiritual survival and physical annihilation, similar to the Schrödinger cat state fact that after humans were infected with the virus in the Earth era, the spirit lost its physical existence. Due to the laws of time and space, objects across the plane cannot exist for a long time, and the cost of existence is extremely harsh. The fact that the spirits are bound to die will not change anything.

It is recorded in the book "A Brief Discussion on the Holy Light Imperial Sword and Sword Refining" of the Holy Light Cross Legion that because it can exercise the soul and care about the kingdom of heaven. Because only pure and noble souls can cross the plane barrier, the Holy Light Crusaders, one of the ascetic groups in the Order of Light, have preserved their true colors as ascetics with love for the Light.

In the interstellar era, the Holy Light Crusader fleet discovered that the Soul Crystal could preserve the soul for a long time, especially suitable for interstellar voyages. After dying on the battlefield, you can turn into a sharp blade and be blessed by the Holy Light, or you can return to the Cathedral of the Holy Light, where your soul can return. The priests of the Holy Light Cross Legion fought bravely in defiance of death, turning into the Fist of the Iron-Blooded Cross of Light and joining the Glory of the Federation.

"The Light is above! My brother! Each other's bodies also return to the void, holding this blade to kill the enemy with glory, incarnating the streamer fearlessly, and returning to his hometown in the dream of soul staying......" Qin Hao read with tears in his eyes.

"Brother! I will take your souls back to the Holy Light Cathedral of Earth in a moment, please help me", Qin Hao said with a clenched fist after reading it. Crystal swords flew around, bowing their heads and whimpering.

At the edge of the blood-colored crosssword area, the ironwood hand dances the laurel order and the black pattern attacks, and Minas holds the halberd to defend the green pattern. Katie stood on the deck, chanting restoration magic to Ironwood and Minas, the energy quantum entangled, and the energy that exuded vitality was transmitted from the Silverleaf City Origin Guardian to Ironwood and Minas.

Zhou Yi was placed on the deck to treat abrasions, and Mo Xiaobei, Nangong Jun, Zhuge Nantian, and Lu Yu piloted No. 02 and No. 03 high-speed planes to remotely block the green pattern to reduce the pressure on the melee Minas.

The Minas flagship unleashed layers of defensive magic, rows of long-range overhanging cannons roared from the gun bay, and armor-piercing neutron flashbangs formed a rain of bullets that covered the center of the black-and-green patterned body.

Qin Hao walked out of the stone cave, with a blood-red cross hanging around his neck, and the golden runes on the cross flashed regularly as soon as they lit up and disappeared. Surrounded by golden and silver holy light, layers of countless soul crystal swords rotated rapidly. Qin Hao walked out of the cave and walked towards the central blood red cross giant sword and the black-green pattern body.
