Cheat Simulation: After I Died, the Empress Went Berserk

[Multiple heroines + love triangle + simulator + empress + multiple worlds + mature woman + loli + young girl] Spiritual energy is reviving, myths are descending, parents are dead, and he's terminally ill. Lu Ming, with all his buffs stacked up, finally sees the system arrive, but something seems off about this system. [Ding! Congratulations, host, you have awakened the cheat code simulator] This system allows you to freely travel between different worlds. You will act as the heroines' cheat code, accompanying them as they grow and experience wonderful lives. [Please note, host, that this system only provides the ability to experience different worlds and does not benefit your health.] Looking at the system introduction that seemed like a joke, Lu Ming was utterly desperate and let himself go. In my first simulation, I became the remnant soul of an ancient demon god in the female-oriented cultivation world. Having personally raised Fairy Luo Chen into a Demon Lord, she died with her life extinguished. As she crushed the skulls of gods, her face contorted with madness, she cried out, "Senior, once I cleave this Heavenly Dao, I will come to find you!" The second simulation: becoming the mentor of a useless summoner in a magical world. He nurtured Elodia into a prodigy who wielded several top-tier summoned beasts. When he turned into starlight to save her, she went completely mad: "Teacher, even if the whole world turns into wasteland, I want you back!" Through repeated simulations, Lu Ming experienced different lives, and his life came to an end without regrets. Finally, in the last moment of her life, time and space shattered, and the girl tore through the sky and descended into the void. The Empress, adorned in her phoenix coronet and wedding robes, reigned supreme over the world: "Senior, I have finally found you!" A blonde girl stood on the dragon's back, everything frozen in ice: "Teacher, you promised to stay by my side through thick and thin. If you dare to die, I'll destroy this world!"
