Divine Bow

An Indian boy died while eating samosa. Reborn in a ruthless cultivation world where fists talk and the strong prey on the weak. Luckily, a malfunctioning System showed up with an apology gift.
Gift One: [The Divine Kavach] - Absolute, 100% damage immunity. Physical, spiritual, soul-crushing? Null. Zero. I'm permanently stuck at age 17, unkillable, and your ultimate attacks feel like a gentle breeze. Try to hurt me? Congrats, you've just made a fool of yourself.
Gift Two: [The Divine Bow of Unparalleled Outcomes] - It unlocks one universe-altering Divine Arrow for every major realm I break through. Fire that vaporizes armies? Space that teleports your head off? Check. There's just one tiny problem...
I CAN'T CULTIVATE.
