Jiang Ling, a modern professional bodyguard, is attacked and killed. He transmigrates to the chaotic age of Yanzhou, where his own elder brother and fiancée frame him and have him sent to the border. Badly wounded and captured, he escapes with his life, then marries into Kaoshantun as a live-in son-in-law.
No System, no golden finger from the heavens. He relies solely on what he learned in his previous life. He hunts tigers and leopards in the mountains, forges goose-feather sabers at a blacksmith's shop, and trains hard in boxing.
The Tujue cavalry from the northern desert rides south to raid, leaving the borderlands devastated. He rises from the wilderness with a saber in hand, rallies the village's able-bodied men to resist the barbarian cavalry, and with nothing but his own hard-won skills, takes on ten thousand horsemen to protect the people of the borderlands!
There are too few articles that slowly pave the way, and it is rare to have unsystematic articles.
The protagonist in the article is real, grows step by step, and is not clichéd. Nice.
