Gods and Ghosts Descend: I Become a Martial Venerable by Selling My Blood

(No harem, no cringe power fantasy, no dumbing down, no System, no invincibility) A global phenomenon called the "Mental Storm" swept across the world, robbing everyone of their ability to sleep. An ordinary wage earner, Xun Jian accidentally transmigrated into a world of illusions. After being struck by lightning for no apparent reason, Xun Jian fell into a coma. When he woke up, he had returned to his master's courtyard. The world of illusions was baffling and mysterious, but Xun Jian only wanted to save his sole blood relative. "I just want to go back to living an ordinary life. I just want to save my little aunt..." By chance, he discovered that his blood had turned black and white. Another calamity forced Xun Jian to press on. Martial Envoys, Martial Emperors, Martial Venerables... There is always someone stronger, and a greater world beyond. A mere Martial Apprentice grows stronger by selling his blood, and from then on, becomes invincible beneath the heavens. "I really don't want things to be like this... Forget it, I'll find someone to deal with you right now." (The author promises the story won't be exciting, so feel free to tear it apart!)
