An antiquities explorer accidentally picked up a jade broken into two pieces, but was involved in 520 rebirths with the Republic of China as the background - each time he brought complete memories with him, and had only one goal: to save the man he disliked when they first met, but who was engraved in his bones in the end.
...520 Reincarnations, he counted the frequency of his trembling, remembered the temperature of the tea he loved to drink, and melted and shattered the protective jade pendant again and again, just to make up for the "almost" regret. But every time, death arrived before the embrace.
In the end, he smiled at the ending in a pool of blood and used the last half of the jade to exchange for his lover's life. When he stood in front of the big screen of the ancient tomb and looked at the 520 failed rescues and the secrets of 520 rebirths of broken jade, he realized that behind those "almosts" was the paranoia of his lover who valued his life. Fireworks exploded on the big screen, reflecting the late confession, and he stretched out his hand, but only caught a piece of nothingness - it turned out that all the encounters and sacrifices were just a doomed redemption before the broken jade burned out.
