In the third year of Yongle, the human world was hanging at the critical point of the collapse of the Three Realms.
When Pangu created heaven and earth, the clear air rose to become the sky, and the turbid air sank to become the earth. Only the southeast corner of the sea cracked open an eternal gap - the Guixu Sea Eye. This eye connects the Netherworld Blood Sea and the Nine Heavens Galaxy. In ancient times, Dayu used the Sea-Dinging Needle to seal it. The body of the needle was engraved with a large formation of stars all over the sky. Half of the tortoise shell was anchored at the end of the needle. The other half was taken by Sakyamuni Buddha to the Buddhist Kingdom of the West, forming a "double lock of heaven and earth".
However, during the war at the end of the Yuan Dynasty, in order to subvert the Dragon Vein of the Central Plains, the remaining forces of the Meng Yuan secretly colluded with the Black Sea Old Demon to pollute the eyes of the sea with the blood of 100,000 prisoners of war. The moment the seal was loosened, seven demon stars fell from the Ziwei Yuan and turned into seven black energy that entangled the emperor star. The Qin Tian Jian classics record: "The Demon Star Chain Emperor, after seven calamities, the dragon energy is exhausted, the eyes of the sea are opened, and the world is ruins."
After Zhu Di ascended the throne, he dreamed of huge waves of blood every night. It wasn't until three years ago when the imperial mausoleum was being renovated that craftsmen dug out a gold coffin inscribed with Sanskrit under Zhu Yuanzhang's coffin, which contained Buddha bone relics and half a tortoise shell. At that time, a vision came from the sky, and a huge Buddha's shadow appeared in the western sky, leaving behind a prophecy: "The golden wings will return eastward and cross the ocean seven times. If the needles are connected, they will be safe. If the needles are broken, they will perish."
This was the true mission of Zheng He's seven voyages - not to "turn Xuande into a distant man" as recorded in history books, but to cross thousands of miles of sea, collect two halves of tortoise shells, and recast the Dinghai Needle before the night of the seventh full moon. The countries along the way are actually the relics of gods and Buddhas scattered in the three realms: the Guli Kingdom contains the relics of the Buddha Tooth Relic Temple, the Khrumos is the ruins of the alchemy furnace of the God of Fire Zhurong, and the Tianfang Kingdom suppresses the fallen angels under the black stone of the Kaaba.
