Longevity: Starting with The Heaven Sword and Dragon Saber

[No System + Multiple Heroines + Decisive and Ruthless + No Saintly Savior] Lu Feng was born in the twenty-second century. By a stroke of chance, he uncovered the mystery behind his family heirloom and discovered that it could let him transmigrate through time and space. After entering the world of The Heaven Sword and Dragon Saber, he became a disciple of Zhang Sanfeng of the Wudang Sect. Everyone knew of the Seven Swords of Wudang, but few knew that Wudang had an eighth sword. It was only when Zhang Sanfeng celebrated his hundredth birthday and Zhang Cuishan returned with his family, prompting the various sects to show up and stir up trouble, that Lu Feng's eighth sword was finally drawn. Lu Feng: "Hmph. You've got some nerve. It's my master's hundredth birthday, and you think you can do whatever you please? If you don't give us an explanation today, there's no reason for your Six Great Sects to exist anymore." Zhang Sanfeng: "Hmph. How could I let you decide whether my disciple lives or dies? Do you really think this old Taoist can't wield a blade anymore?" Cheng Kun: "It's all because of you, you villain! Years of my plans have been ruined!" Zhou Zhiruo: "Brother Xiaofeng, I think I'm sick. Could you take a look at me?"
