A Mortal Girl Cultivates Immortality, from a Peasant Girl to the First Swordsman

[Ordinary female cultivating immortals + no CP + strong female + no system + hard core and slow heat + supporting characters with brains + steady development + non-cool writing] Dressed as a peasant girl, Yan Hua doesn't want to get married, she just wants to become an immortal. No strength? Practice! No master? Try to find! No resources? Rob! After five years of chopping firewood and carrying water, I developed enough strength to climb a mountain gate until I vomited blood and fainted. After waking up, she became an outer disciple, learning medicine from the widow, and learning breathing from Senior Sister Bingshan. Others practice Kung Fu to live forever, but she practices Kung Fu to stay alive. But she wanted to try—— Mortals, can you defy this world? Later, everyone knew—— That crazy girl from Kongwu Sect who didn't want her life became an immortal. The early upgrade of the protagonist is very painful and can even be said to be cruel. It is not poisonous, such as betraying the bottom line of dignity, but it may be unexpected.
