Doomsday? The Cyber Ancestors Arrive to Save the Day!

[Parallel universes + high-tech Qin/Han/Tang/Song/Ming dynasties + ensemble cast + battles among the stars] In the Great Ming Empire, Year Nine of the Zhaoxi reign, visitors came from beyond the heavens. The alien fleet was so powerful that hope seemed lost. Foreign nations one after another became their lackeys. If you intend to destroy our country and exterminate our people, then even if we die, we’ll take some of you down with us! The “Sumeru Seed,” able to grow or shrink at will, burst onto the scene and destroyed the capitals of two great powers in succession. Sadly, even after the Great Ming warriors had shed their last drop of blood, they still could not defend their homeland. Just as everyone was sinking into despair, scientist Song Kun developed a program that could make contact with parallel universes. And so The emperors of parallel worlds crossed the stars and arrived in all their domineering glory! Qin Shi Huang: “Seeking common ground while setting aside differences? Nothing more than an empty theory.” “The universe is vast, yet it does not belong to Great Qin. What a pity.” “In this world, there is only Great Qin!” Emperor Taizong of Tang: “Silla, Baekje, the Japanese, Tianzhu, Jiaozhi... Back then, you were all tiny states that bowed at my feet. And now, a thousand years later, you dare show disrespect?” “In those days, my Ninth Son could help you establish your countries. Now, I can still destroy them!” Emperor Guangwu of Han: “Xiaobai, I told you not to relieve yourself wherever you please. See? Did you hit the flowers and plants? Oh, those were just the first shoots. Never mind, then.”
