I Have Great Dharma, But My Elder Sister Persuades Me To Return To Secular Life?

Lu Xuan traveled to the ancient world, became a Taoist priest, and activated the "Eight Wonderful Skills" System.
As long as he slays demons, he can gain merit points, which can be used to unlock eight magical skills!
[Unlock the Liuku Immortal Thief, just eat the treasures of heaven and earth, and your mana will soar? 】
【Unlock the Tongtian Rui, draw the talisman with bare hands, and throw the talisman away in a fight for no money? 】
【Unlock both hands, Pindao also knows some medical skills, he can cure those who are missing arms or legs! 】
【Unlock the Divine Machine Hundred Refiners...】
Soon, Lu Xuan, who has mastered the eight magical skills, has mastered the magic of the heavens and suppresses all evil spirits in the world!
But one thing gave him a headache. His sister tried hard to persuade him to return to secular life all day long.
"My good brother, you are the only one left in our family. The incense must not be cut off! Just listen to my sister's advice and return to the secular world!"
"Master Lu in the city loves his daughter, a virtuous and polite woman. The other party said that if you nod in agreement, she will immediately take 200 acres of fertile land with her. Get started with dowry!"
"The girl that my sister rescued is also pretty, gentle and beautiful!"
Lu Xuan raised his head helplessly, "Sister, can you see clearly? She is clearly a thousand-year-old snake demon!"
