In 1765, the Burmese army came to the city of Ayutthaya. Baser, the seemingly cowardly guardian of the royal tombs, is actually a descendant of the "Dragon Guardian Clan". He possesses the secret method of connecting to underground spiritual veins and the [Dragon Vein Resonance System] that can sense historical fragments. He met Tavi, who claimed to be the daughter of a down-and-out noble, a 21st century war correspondent whose memory was sealed. She secretly mapped spiritual nodes and city defense loopholes with her surveying and mapping skills that transcended the times.
The two formed a secret alliance when the city was destroyed: he manipulated formations to create "miracles" deep in the tomb, and she used modern military knowledge to build a survival network. They discovered that the real enemy was not the enemy outside the city, but the royal prince inside the city who had colluded with the evil cultivator "Spirit Devouring Cult" in the Western Regions and intended to sacrifice all the creatures in the city to swallow the dragon's veins. When the final altar was activated, Tawei regained all her memories - she was originally a recorder for the Time and Space Restoration Bureau, and her mission was originally to observe history. Now she must make a choice between "faithfully recording the collapse of the dynasty" and "defying the laws of time and space to save the common people"; and Baser also faces the ultimate price of blood inheritance: to protect the dragon vein, he must sacrifice his body.
This is a guardianship with an undercurrent in the historical destiny - it is impossible to reverse the overthrow of the dynasty, but can it preserve an immortal aura for this land?
