Traveling Through the World of Cultivating Immortals Begins with the Son-In-Law

[Cultivation of Immortality + Son-in-law + Funny + System] Lu Renjia, who failed on a blind date, was struck by lightning and was transported to the world of immortality. At the beginning, he became a son-in-law with a system, and began a life of cultivating immortality (you can't lie flat on your back, and you need to be beaten to level up. How do you lie down)? He randomly picked up two children, one was a swordsman genius, and the other was a reincarnated master.
