(Ask for recommendation votes, ask for collections!)

The alloy door of the armory slowly opened, and the Nie family left Shi Kong with a waiting look and walked in with a sword.

The woman stepped forward, this time very resolutely, without looking back, Shi Kong watched the withered back disappear into the alloy door, and wanted to speak several times, her fists clenched, but she held back.

In fact, he had already noticed the abnormality, and the woman did not take the initiative to speak, and the mother and son finally chose to remain silent tacitly.

It didn't take long, and when the alloy door of the armory opened again, only the Nie family was left in front of Shi Kong.

The heart trembled almost uncontrollably, the fingertips pierced the palm, and a red overflowed from the five fingers, and then dripped to the ground, drop after drop, like an hourglass of time, never ending.

The first thing handed to Shi Kong was his sword, which was wrapped in a black cloth and served as a scabbard, and the long sword seemed to be nearly a kilogram heavier than before, and it felt a little more flesh and blood.

After being silent for a long time, the Nie family handed over the second thing, which was a folded piece of rice paper, the paper was dim in color, obviously an old paper that had gone through the years, and a little ink had penetrated the back of the paper, and it had not completely dried up.

I almost trembled and opened the page, but I saw that the pen was very beautiful, and it was even more golden, and there were only two sentences.

The first column from the right hand: "Ten years of life and death, without thinking, unforgettable." ”

The second column: "Bone and blood become a sword, and the bright moon is geometric, this sword and bright moon, he, owes me a sword." ”

......

"Bone and blood become a sword, this sword is ...... Mingyue," Shi Kong muttered, his hand holding the rice paper hard, slowly crumpling into a ball.

The bloody hand grasped the hilt of the sword, and the sword body was pulled out inch by inch, and the ink-like sword body had turned dark purple, as if it had been soaked in blood, and had dried up for another ten thousand years.

"This sword bright moon!"

He said word by word, and he laughed loudly, like a madman, and tears flowed down his eyes.

In front of the armory, the Nie family looked at the young man in front of him, fighting for more than ten years, strategizing, and couldn't help but feel a little sad.

After a long stick of incense, Shi Kong's laughter gradually stopped, wiping away the last tear, he raised his head, there was no sadness on his face, but in the depths of his pupils, there seemed to be a thundercloud burning.

"General Nie, please take me to the space-time corridor. ”

He looked at the Nie family in front of him, spoke solemnly, and bowed deeply.

Looking at the young man in front of him steadily, the Nie family sighed for a long time, sighed, and said, "Come with me." ”

In the cold alloy corridor, two figures, one large and one small, gradually faded away, and under the light, the shadows of the two were stretched and spread into the dark distance.

......

I don't know how long I walked, how many bifurcated roads I walked into, and the long alloy corridor finally came to an end, and a strong smell of decay came to my face.

Shikong frowned, looking at the ancient stone walls around him, although uneven, but more moist than seed jade, there is a faint glow floating, illuminating the road ahead.

The Nie family stopped and did not continue to move forward, the two stood side by side, and for a while, no one spoke.

"Do you know what spacetime is?"

Suddenly, Nie Jiaqi spoke, his tone calm, but Shi Kong keenly captured the endless memories.

What is time and space? The upper and lower four directions are called the universe, and the past and present are called the universe?

Shi Kong suddenly found that he had never thought about such a question, what is time, what is space, and what is time and space?

"I don't understand. After a moment, Ishiku shook his head.

"I don't understand either. Nie Jiaqi smiled, he took a deep breath, and said, "The understanding of space and time has always been closely related to the understanding of the universe, and modern cosmology is based on the principles of cosmology and Einstein's gravitational field equations. The cosmological principle holds that the universe as a whole is evolutionary in time, that is, there are arrows of time, and it is uniformly isotropic in space. In the middle of the 20th century, the Big Bang model of the universe was proposed, which explained the redshift of galaxies outside the river, predicted the cosmic microwave background radiation, gave an explanation that was basically consistent with astronomical observations for the evolution of the universe and the formation of galaxies, and also solved the problem that the Newtonian system could not establish a picture of the universe, which was just the beginning. ”

After a pause, Nie Jiaqi continued: "More than a hundred years ago, in Taizhou City, Jiangsu Province, China, the Ancient Dragon Cave, a third-level ultra-ancient ruin, was discovered, and at the same time, there was a disappearance of people. ”

"Time and Space Tunnel. Shi Kong muttered, the so-called space-time corridor, is it the same?

"The space-time tunnel is a passage from one place at one time to another place at another time, and it is a paranormal phenomenon that the scientific community is keen to explore. In the eyes of those who step into the space-time tunnel, it seems that only a moment has passed, but in our three-dimensional space, a long time, even years, or even more time has passed. Nie Jiaqi looked at Shi Kong, "Do you understand? Or, it can be regarded as a trip, but you don't know the way forward, you don't know the way back." ”

"I don't regret it. ”

Shi Kong said in a deep voice, about the time and space tunnel, he also recalled some classical codexes he had read, among which the "Wuling Ji" said that in the twenty-sixth year of Emperor Yuanjia of Song Wen of the Southern Dynasty of ancient China, Wen Guangtong of Teng Village, Chenxi County, Chenzhou, saw a wild boar eating the crops in his field, so he raised an arrow to shoot the wild boar. After the boar was hit by an arrow, it bled and fled. Wen Guangtong followed the bloodstains and chased more than ten miles, entered a hole, walked more than 300 steps, suddenly opened up, hundreds of houses suddenly appeared in front of him, but he didn't know what place it was, and then look at the pig he shot, it had run into the pigsty of the villagers, and after a while, an old man came out of the house and asked him: "Did you shoot my pig with an arrow?"

Wen Guangtong replied: "I didn't shoot it intentionally, it was it that ate my crops, so I shot it." ”

The old man said: "That is the sin of this pig's life in the previous life, and you deserve such retribution in this life, so you don't have to apologize." ”

When Wen Guangtong returned to the previous entrance of the cave, he found that the bow and arrow used to shoot the wild boar had rotted and broken. Later, when he arrived home, he realized that he had only been in the cave for a while, and that twelve years had passed in the world, and that his family thought that he had already passed away and had done a funeral for him, and now that he had returned, the whole village was shocked and puzzled. However, the next day, he and the villagers found the entrance to the cave, only to see that a huge stone had blocked the entrance of the cave, and no matter how much they burned and chiseled, the hole could not be opened, and the boulder and the mountain had become one.

Obviously, in this legend, the original Wen Guangtong walked into a time and space tunnel, but after reading this story, Shi Kong at the beginning also wondered that two different time and space, two pigs with the same head, really have reincarnation in this world, is there a past life and this life?

"What exactly is space-time, where is the other end of the space-time tunnel, who in the world can tell, only those who really enter it know. Nie Jiaqi sighed, "It's a pity that the development of science and technology has made it possible to cover every corner of the solar system, but for the proposition of time and space, I still don't know anything, a space-time corridor, how many people have been buried in the past fifteen years, and it is finally time to end." ”

What the?

Shi Kong captured another layer of meaning from the words of the Nie family.

"Let's go. ”

Nie Jiaqi didn't explain, and took another step, the ancient road was not very long, just walked for a while and reached the end, and soon, Shikong saw a familiar land.

The vast earth, which does not look like a mountain belly at all, has the sound of the wind whimpering, and the sand and dust dancing, blocking the view.

But even though his vision was blurred, Shi Kong still locked on to the corridor engraved in his memory for the first time.

It seems that the cloister of the ancient Chinese royal garden, the blue brick tile, the vermilion column, the quaint bluestone pier, the eaves are high pecked, extremely elegant, but compared with four years ago, it is more dilapidated here, whether it is the column or the bluestone pier, it is full of cracks, as if the ice cracks of Longquan celadon, revealing a strange beauty.

If it weren't for the devouring and burial of too many people, in the eyes of many archaeologists, this place was probably a rare underground ancient city, which sank into the ground due to many unknown reasons such as crustal movement, and has been sealed to this day, but unfortunately, in the eyes of the Nie family now, it is like an ancient beast that is better than all. (There is also the last chapter, the first volume is coming to an end, the vast ancient land is about to kick off, everyone is looking forward to it, finally, please help the Heavenly Emperor of the Terran Race, please believe that although the purple pole is slow to heat, it is absolutely wonderful.) ）
