This is the story of the whole martial arts world fighting for a sword and finally finding out that everyone has been fooled.
Male protagonist: A miracle doctor whose poison skills are better than his medical skills. Delicate appearance, lazy, cold, and mean-tongued (please note that this is not a vicious tongue out of bad taste in the general sense, but a real mean-mouthed person). Don't know martial arts.
The heroine: a little beggar with unknown origins and a gangster spirit, tops the "never mess with" list. Smart, cunning, undisciplined, a good drinker, and carries a dagger with him. He looks free and easy, but in reality he is ruthless (he is really sinister, but he is also really ruthless).
P. S. Although the writing is a bit coquettish, this is actually an ancient, serious and orthodox piece of martial arts + battle of wits + romance. Conspiracies, swords and swords, in the end, the word "love" cannot be escaped.
P. S. Don't forget to wear an IQ, not too many. Anyway, the author's isn't quite enough.
