After Achieving Immortality, My Junior Sister Says I'm So Cautious I'm Practically a Coward

【Everyday life + longevity + cautious schemer + calculating + nurturing + devoted to his junior sister + lighthearted comedy】 Lin Changsheng became immortal. Born in the Western Zhou dynasty, he lived into the modern era. He survived wars, assisted wise rulers, launched rebellions, and witnessed a series of massacres, including the Upheaval of the Five Barbarians. He was once passionate about immortality, but now finds it dull and tedious. He once pursued the path to immortality, too, only to discover that all those gods and Buddhas in the heavens were nothing more than spiritual beliefs invented by people. Now the earth is cracking apart, the whole world is frozen, and oxygen is running out. No one will survive. So Lin Changsheng buried himself in his ancestral grave. 【Turtle-Breathing Art: Activated.】 "What the hell..." One day, his stone coffin was pried open, and a gleaming flying sword was pointed at his neck. An immortal? An immortal maiden? Neither! They were two cultivators from the Tianjian Sect who had stumbled upon him by chance. Standing on flying swords, the two took Lin Changsheng to their sect to test his spiritual roots. In a secret realm. The Daoist and Buddhist sects formed a temporary team, while the demonic sect and the demonic cultivators each formed their own. A fake monk had seized a female disciple of the Tianxuan Sect and was about to assault her. Lin Changsheng happened to see. Should he save her or not? When he saw Mo Lan's breathtaking beauty, and her body beneath clothes torn to rags, Lin Changsheng gave an evil grin and pulled out a thick stack of spirit talismans. "Explode!" In Gourd Valley, five demonic cultivators fought until two were dead and one had fled. Lin Changsheng thought no one had spotted him, but a demoness saw through his hiding place and called him out. Demoness: "Help me kill him, and I'll give you an Earth-grade cultivation manual!" Man: "Kid, I advise you not to stick your nose into this. You won't even know how you died!" Lin Changsheng rolled his eyes and said disdainfully, "You two carry on. I'm not getting involved!"
