But this netherworld is not terrifying, but has a dome as bright as day, full of strange flowers and plants, very different from the natural landscape of the world, and even a large black ocean - Qin Muye named it the Heart of the Earth Sea.

Li Longqi witnessed all kinds of strange animals—the huge unicorn like a hill, the divine dragon flying in the air, the nirvana phoenix that threw itself into the sea of fire and did not die, and the ancient monsters that flickered in the ocean.

He also saw the same divine deer as the nine colors, all of which were several times taller than the nine colors, and they were all adult divine deer, shaped like moving three-story buildings. In another three thousand years, when the nine colors grow up, it will probably be so huge.

Qin Muye knew that this day was coming sooner or later, and he told Li Longqi a secret, a secret that the ancestors of the Qin clan had inherited for two thousand years-

In ancient times, it was an era of coexistence between man and God. The so-called gods are divine beasts. The ancestor of China, Fuxi Nuwa, is a human head and a snake body. The green dragon, white tiger, vermilion bird, and Xuanwu representing the four directions are also ancient mythical beasts. What's more, the dragon gave birth to nine sons. There are also ancient books such as "The Classic of Mountains and Seas" and "The Book of Divine Differences", such as Kui, gluttony, chaos, Bai Ze, Qiqi, Hanqi, nine-headed bird, and three-legged black......

Man learned the skills of conquering nature from the beasts, and used these skills to defeat the beasts.

Because human beings have a power that divine beasts do not possess - conspiracy.

This power has helped human beings to gradually grow from being as weak as ants to dominating all species in nature, becoming the primate of all things and the master of heaven and earth. Human beings have changed the direction of the river, leveled the hills and forests, made the Tong Mountain wet, the Yellow River accumulated sand, reclaimed the Qianmo vertical and horizontal, and built the city wall palace, high-rise buildings.

The greatest buildings and monuments of mankind are mausoleums.

At the beginning of the Yin Shang era, all kinds of mythical beasts were sent into the mausoleum by humans and directly domesticated and transformed into tomb beasts. Not only to protect the monarch's mausoleum, but also to permanently control the mythical beasts underground, so that they no longer become gods on earth. The craftsman who was responsible for domesticating and transforming the tomb beast back then was the ancestor of the Qin tombsmith clan today.

In the Spring and Autumn Period and the Warring States Period, the mythical beasts gradually became extinct on the surface of the earth due to the expansion of human living space. The Gravesmith Clan and the Divine Beast exchanged souls, and on the back of each generation of the Gravesmith Clan, a red birthmark in the shape of antlers appeared, which was a seal given to them by the Divine Beast. Therefore, the Gravesmith Clan has inherited the power of the Divine Beast for generations, and only the bloodline of this clan can build the Tomb Beast.

The Gravesmith clan was not satisfied with the power of the divine beasts, they worshiped under the Mozi Sect, became a member of the "Ink Maker", and learned many superb skills. When the casting technology of bronze and iron tools was popularized, people found mysterious spirit stones in Taihang Mountain, and the tombsmith clan integrated the skills of the mythical beasts and humans to create a completely mechanized tomb beast, which was dedicated to the monarchs of the Spring and Autumn Period and the Warring States Period, and there was no need to domesticate the mythical beasts.

Qin Shi Huang unified the world, and the tombsmith clan built the magnificent Mausoleum of Qin Shi Huang, and built a tomb beast for the first emperor, so he was given the surname Qin.

Legend has it that the mythical beast is not completely extinct, and there is an endless world thousands of feet underground. It is the last paradise of the mythical beasts, undisturbed by humans, and they live freely. But no human being has ever seen this world.

It is said that there are also some divine beasts left in the mortal world, hidden in the Qinling Mountains and Ba Mountain, inaccessible places - such as the Nine Colors ......

Li Longqi and Qin Muye withdrew from the underground world, closed the entrance to the deep well, and forbade anyone to dig any further.

However, it was no longer Li Longqi who was in charge of supervising the mausoleum project, but his half-brother Li Longji. In order to carry out Empress Wu Zetian's order, Li Longji ordered the construction period to be stepped up, and all lazy people were to be whipped, and the following year's forced labor was increased. Everyone didn't dare to slack off, some people couldn't bear it, and it would be a death to dig like this, so it was better to follow Chen Sheng and Wu Guang to rise up - all of them were suppressed by force by the Praetorian Guards, and those who participated in the rebellion against the rebels were either divided into five horses, or lit sky lanterns, and even the nine clans.

Li Longji is a few years older than his younger brother, and he is jealous of Li Longqi for getting the favor of the empress. When he heard that Li Longqi had escaped from Luoyang and infiltrated the construction site of the Bailuyuan Tomb, he ordered the Praetorian Guards to pursue him.

With the help of Qin Muye's death, Li Longqi escaped from Bailu Plain by luck, took the nine-colored deer through the pass, and came to the Qianling Tomb where his grandfather Gaozong Li Zhi was buried.

On this day, Wu Zetian led hundreds of civil and military officials to worship Gaozong Li Zhi and set up an unprecedented wordless monument. Li Longqi immediately appeared, but was stopped by the Praetorian Guards. Seeing this, Di Renjie and Li Chunfeng ordered Li Longqi to be sent to the empress and begged Wu Zetian to forgive the child.

Li Longqi bluntly admonished Wu Zetian and strongly persuaded Wu Zetian to give up the Bailuyuan project. He quoted Mencius as saying to King Qi Xuan –

"The king regards the minister as a sibling, and the minister regards the king as the heart; The monarch regards the minister as a dog and a horse, and the minister regards the monarch as a countryman; The king regards his ministers as mustard, and the ministers regard him as an enemy. ”

The empress was furious that "the children cannot be taught", and ordered Li Longqi to think about it behind closed doors in the Luoyang Palace.

Seeing that persuasion was hopeless, Li Longqi stood in front of the wordless monument, pulled out the dagger that had been prepared for a long time, and stabbed himself in the chest.

The fifteen-year-old little prince pierced his heart on the spot, and blood splattered five steps. The bright blood of the young man, the Kunlun warm jade that stained the chest red, and the wordless tablet were also dyed red.

This unexpected scene actually made Empress Wu Zetian faint on the spot. The ministers were also shocked, and when Di Renjie and Li Chunfeng rushed closer, Li Longqi, the king of Zhongnan County, had returned to the sky.

The boy's last words - Chaowen said, it is okay to die at night.

The moment the blood smeared the wordless tablet, it radiated a thousand feet of golden light, and the wordless tablet was already covered with words. Wu Zetian woke up from a coma, hugged his dead grandson, looked at the words on the wordless tablet, and the old tears were all over the place, and she was the only one who could see every word on the wordless tablet.

A moment later, the sky rained rain, lightning and thunder, and the weeping raindrops swept across the Guanzhong Plain like the arrows of the Tang Army Formation, and also washed away the words on the wordless stele, and never left a word in history.

Empress Wu Zetian ordered the construction of the Bailuyuan Tomb to be suspended, allowing hundreds of thousands of Li people to return home, pardoning three years of forced labor, and compensating them for the hardships of the past few years.

The underground palace that has been completed in Bailu will bury Wu Zetian's most beloved grandson, the most outstanding son of the Li clan in Longxi - Li Longqi, the king of Zhongnan County.

The nine colors of the deer voluntarily accompany the owner permanently. Qin Muye transformed it into a living tomb beast. It will guard the underground palace for thousands of years. When Li Longqi was buried, Li Chunfeng stuffed a pill into his mouth and accompanied him to enjoy eternal glory. The Kunlun warm jade, soaked in the blood of the little prince, turned into a warm blood jade, and was buried under the nine springs, waiting for the next destined person to arrive.

In the second year, the Shenlong coup d'état, Wu Zetian's first Zhang Yizhi and Zhang Changzong were killed by the ministers. The Empress Zen throne was given to Li Xian, which was for the revival of Tang Zhongzong and the Tang Dynasty. In the winter of this year, the eighty-two-year-old Wu Zetian collapsed in the Xianju Hall of Shangyang Palace. She issued an edict, removing the emperor's title and changing it to "Zetian Great Sage Empress". In May of the following year, Wu Zetian was buried in the Qianling Tomb and finally slept next to Tang Gaozong Li Zhi.

The above is the origin of the Tang Dynasty tomb in Bailuyuan.
