Stack the Thickest Armor and Take the Hardest Hits [Infinite]

Every newcomer gets one chance to draw a prize the first time they enter the Infinite World. The top-tier prizes include dragon bloodlines and demon servants. The next tier includes twin fire blades and frost bows. Even if your luck is terrible, you can still draw a few bottles of magic potions. But Yun Xiaotang... She drew a dull gray tortoiseshell??? Watching the other newcomers celebrate, Yun Xiaotang held the tortoiseshell, with no idea what it was for, and fell into thought. She stayed weak, pitiful, and helpless in the Infinite World, until the first time she got hit. She discovered that every 1,000 points of damage she took increased her tortoiseshell's defense by 1 point. And for some unknown reason, whenever her tortoiseshell was about to shatter, some inexplicable force would repair it. Yun Xiaotang stopped playing it safe! She got back on her feet! She fearlessly challenged bosses again and again, taking the most brutal beatings and going down more than three hundred times. The onlookers couldn't bear to watch: This is too cruel. The boss is utterly inhuman! The boss was then killed by her, one slash after another, while enduring the weakest attacks and getting hit more than three thousand times. The onlookers stared in shock: This is insane, Yun Xiaotang! You're downright ruthless! Please leave the boss with a whole corpse!!! Ji Wang was one of the first veteran players to enter the Infinite World. He had never lost and had an impeccable record. After completing yet another dungeon mission flawlessly, he acquired an egg belonging to the divine beast Xuanwu. He invested plenty of resources into it, and finally managed to hatch Xuanwu. Then the very next day, Xuanwu's shell vanished. All that remained was its limp body, which tearfully told him that it could sense its shell outside, on the verge of breaking, and that it needed healing potions to nourish it. Ji Wang: ... What the hell, the shell flew away. Where's my enormous turtle??? *The title comes from an internet slang term. *All in all, it's probably a story about a little turtle looking for its shell (...) Theme: Never give up. Keep fighting after every defeat.
