Multiverse Great Qin: Father, You Hid Your Secrets Deep!

[Technology] + [Cultivation] + [Myriad Worlds] + [First Emperor] + [Great Qin]

After the First Emperor unified the six kingdoms and performed the Fengshan sacrifice at Mount Tai, he gained a chance at immortality. He built a bronze gate that could instantly open doors to other worlds.

In pursuit of eternal life and to make every citizen of Great Qin as powerful as a dragon, he led the empire down a path of plundering resources from other worlds.

That year, a soul transmigrated from the modern era, bringing with it a bronze technology tree, and became Hu Hai, the First Emperor's eighteenth son.

The First Emperor had assumed that he would lead Great Qin to become an Immortal Qin...

But many years later, looking back, he saw that

A multiverse-spanning Great Qin where Cultivation and technology coexist had risen above the Myriad Worlds.
