Pokémon: The Reemployment of the Retired Champion of Paldea

A year after transmigrating, Lucas Blade, forced by circumstances to become a trainer, accidentally passed the Champion Exam. Immediately afterward, he announced his retirement on the spot, stating that, having once suffered through the 996 grind, he now just wanted a leisurely and peaceful life. However, just as he invested a huge sum to buy land and planned to build his farm, his long-delayed golden finger (cheat ability) finally arrived. At this time, the Tera orb had not yet been developed, and Sada/Turo had not yet become completely obsessed with the research of Area Zero... On one hand, there’s a special hint system in his chat group secretly helping him grow stronger; on the other, there’s the increasingly bizarre farm, thanks to the random appearances of strange people and Pokémon. On top of that, he still has to deal with the various students with different personalities at Naranja Academy, where he works... From that moment on, Lucas’ peaceful life began to stir with new waves. — Description from novelcodex.org
