Once upon a time, three travelers arrived in the Lapis Lazuli Pure Light Realm, the private domain of the Medicine Buddha, a secret realm constructed early on by the Buddhist sect.
In the Lapis Lazuli Pure Light Realm, there was neither suffering nor disaster; all its inhabitants were affluent. Whatever food one wished for would manifest itself at a mere thought. This was the supreme Great Divine Power, blessed with the destiny of the Future Buddha Medicine Tathagata upon this secret realm, making it extraordinarily powerful.
Now, the real Medicine Tathagata was about to be born into the Pure Light Realm, but the current state of the Buddhist sect was bleak. If no one went to guide him, he might very well be strangled in his cradle.
