My Broken Phone Connects to a Warlord's World

My lazy brother doomed me to a broken, twenty-yuan junk phone. But this wasn't just any cheap relic! It instantly repaired itself, becoming an indestructible, infinitely charged marvel. Inside? A mysterious \"Mystic Store\" offering impossible power-ups like Quick Thinking Pills and Beauty Elixirs. The catch? Points are earned by chatting, calling, or video-chatting with Qin Yuchuan, an ancient general from a war-torn parallel world who thinks \"tanks\" are chariots. Now, this ordinary college student is accidentally becoming the most influential person in another dimension, one text at a time. Can I level up myself and save his world without him discovering I'm just a girl with a magical phone?
