Martial Venerable Behind Enemy Lines

The Lin family is massacred, and young master Lin Hanguang is left a cripple. After three years in hiding, he returns with four beautiful companions and makes his start in Yun City. He outwits a Japanese plot, executes traitors, reclaims his family estate, and fires the first shot of the War of Resistance. Moving behind enemy lines, he grows from a lone martial artist into a commander of three armies, builds a base area, forms a special forces unit, and repeatedly defeats powerful foes.
