From Riding a Bird to Riding a Phoenix? How Did You Become a Cultivator?

[Survival at High Altitude] [No Female Protagonist] [System] Why did we say we would ride a bird to survive instead of riding a phoenix to become immortal? And becoming stronger still depends on eating the soft rice of the Phoenix at your feet? Do you think Qin Shihuang was like this too? That won't work! Not only do I want to cultivate immortality, but I also want to sell arms. I want both technology and immortality cultivation!
