[Alternate Continent + Immortal Cultivation + Gu + Otherworldly Continent + Transmigration + Self-Interest]
A friendly warning: The protagonist has a morally chaotic, neutral outlook. He judges right and wrong, good and evil, solely by whether they benefit him. Anyone who benefits him is a “good person”; everyone else is branded a heretic.
After weathering a little over two thousand years of hardships, he transmigrated and was reborn as Tian Du Qing Cheng.
With the memories of two lifetimes, he became one of the Deva, the highest caste.
He also belonged to one of the four oldest families in that caste.
At the end of the dynasty, cultivators and technology coexist... See how he makes the most of this otherworld.
A protagonist who is so upright he veers into evil.
