using his blood

The Blood Pill was refined by condensing a large amount of life essence. It could strengthen one's Qi and blood. It was a shortcut for a Rank-4 to quickly advance to Rank-3. However, there was a prerequisite: one had to have great luck to have a chance of withstanding the backlash. Otherwise, ordinary Rank-4 would almost certainly die if they consumed the Blood Pill.

I recommend a few ancient romance novels. "Dislike Wife and Good Mother," written by asking for medicine and seeing a doctor, through strange feelings. The female protagonist was submissive but not her husband's heart. She was abandoned by her family and took the initiative to take a concubine for her husband. After rebirth, she had to protect her child and fight back against the concubine. The author's new book,'Wife's Power,' has been updated continuously. Purple Bamboo Fragrance's " Promise of a Thousand Gold Doctor " was a classical genre. The female protagonist tried her best for her sister, but she was schemed to kill her. After rebirth, she wanted to make the person who harmed her pay the price and take back her son to find a good match. Shu Shu's " The Beauty of a Woman " was a classical genre. The female protagonist had to live a hard life, and her family was in a lot of trouble. She didn't want to be a person with her tail between her legs. She wanted to overthrow the original owner's misdeeds, help her biological mother to rise up and punish her family, and have an interesting interaction with a certain man. Lady Thirteen's " Reborn Daughter " was a classical genre. In her previous life, she had retreated and was miserable. After her rebirth, her daughter had to fight with her sister to get rid of her aunt to collect debts and protect her lover to show her peerless beauty. Ruffian House's << Noble Clan's Direct Murder >> was a classical genre. The female protagonist endured for her family and love, but was deceived. She was reborn only for revenge. She wanted to throw her family, husband, and emperor who had hurt her into hell. Everyone, please support the newcomer's new book. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

One reason could be to gain power. In fanfiction, the author might want to show Harry in a situation where he needs a significant boost in power and blood magic seems like a way to achieve that. Another reason could be for revenge. If he's been wronged greatly, he might turn to blood magic as a more extreme form of retaliation.

No, it's not true. This is just an unfounded rumor.

I recommend Blood Jade: A Suspense-mystery Detective novel, which tells a mysterious story about blood jade. The male protagonist's parents lost their lives because of this piece of blood jade. The male protagonist began to pursue the truth and encountered many dangers. The plot of this novel was complicated and exciting. It was a mystery novel worth reading. I hope you like this fairy's recommendation. Muah ~😗
