After being pregnant for eighteen years, I am a well-known waste in the whole continent. The Magic Academy said that my spiritual hub was blocked, and the Warriors Guild laughed at me that I had no vitality. Until that day, the system hit me in the back of the head: "The Goddess of War system has been activated." I was confused: "I am a pure man!" The system cried: "The signal is blocked by your muscles..." Novice task: wear women's clothing. I spent a thousand gold coins to take off a woman's robe from a female mage, hung it on my arm, and the system passed the judgment. Reward 10,000 blood experience cards, kill three men in black robes in three seconds. After using up the experience card, I discovered that as long as I wear women's clothing, my blood will increase on its own. You can become stronger even while lying down. From then on, I started trying on my sister's clothes. But now the problem is coming, my sister went home early. I have worn all of her 600 pieces of clothing and haven't washed any of them. I asked online how I can avoid being beaten to death by my sister. It's very urgent.
