Purple Gemstone from Another World, Bound to a Demented Girl at the Beginning

[Non-invincible style + Survival in another world + No intelligence + Sword and magic + Two-way redemption + Single female protagonist] If it doesn't meet your expectations, please take a detour! The protagonist will not be very cold-blooded at the beginning! It is unreasonable in itself! Traveling through another world, Dai Yi did not become Long Aotian, but turned into a stone! Or a purple gem hanging around the neck of a silly girl? ! Fortunately, gems are useful. They can peek into the innermost thoughts of people and chat with silly girls. It's just that this partner is really unreliable - apart from eating and sleeping stupidly, he will hold a broken jar and cry out when he's hungry. But this world is even more outrageous! Cults are rampant, villains are in power, and even drinking water can kill you. Seeing that the silly girl was about to be bullied to death, Dai Yi became angry: Are you really a stone and has no temper? Peep into privacy? Get it you! Demagogue? I'm familiar with this! Command the silly girl to repeat the reading, slap her in the face and counterattack, and find a way out of a desperate situation! It's just that the look in his backer's eyes is getting weirder and weirder, the pursuit in the dark is getting more and more fierce, and the silly girl's ignorant life experience seems to hide a shocking secret... Dai Yi: "Stop staring! I'm really just a stone trying to make her fat!" A jewel with a broken mouth, and a girl who relies on him wholeheartedly, they are each other's armor and survive together in this cruel world.
