My Engagement Was Broken Off at the Beginning, but I Relied on the Xuanyuan Necklace to Counterattack

"According to the Changliujie practice system, you should first mix Bai Linglang blood with Wugu Jade powder and Bixian dew, and take it to generate qi and blood and condense the muscles and bones."
