Retired Swordsman Forced to Open Business

I was once the strongest sword god in the three realms, but now I just want to fish in my sect and retire. Until it was tied to the Kendo Promotion System, he was forced to promote the "Kendo Performance Examination" in the world of immortality. I will focus on the geniuses of the Immortal Sect, and give the Demon Lord five years of tribulation and three years of simulation. I thought it was just a formality, but unexpectedly, the sword manual I threw away became a must-memorize for the college entrance examination, and the junior I scolded became the elder who wrote the questions. At the Fairy Gate Competition, the sword dynamics I compiled was praised as a standard. And my sworn enemy, who was almost turned to pieces by my sword energy back then, is sitting in the audience as a special judge... He stared intently at the syllabus for the All-Immortal Kendo Level Examination in my hand, his eyes seeming to spit fire. This novel and its characters are purely fictitious.
