I, the Dragon King of the East, Strayed into the Fantasy of the West

I, the Eastern Dragon King who controls clouds and rain, accidentally fell into a two-sided world filled with swords, magic and lizard-like dragons. The dragons here breathe fire and fight, and are chased and slaughtered by humans. I wanted to keep a low profile until a red dragon breathed fire at me. I could have summoned the real fire of Samadhi and burned it into a bald chicken. The human brave wanted to make a contract with me, so I directly summoned the Nine Heavens Divine Thunder. Now, they kneel down and call me "Dragon God", and I look at this dry land and think about a serious question: to make rain here, should I use the original version of "Rain Making Technique", or should I use a localized version?
