An inexplicable time travel and an inexplicable system. Is it a blessing or a curse? See how Lin Xuan unified the ancient world and wrote a legend in this vast universe.

When mankind was in crisis again, he stepped forward again, only to be reviled by thousands of people, and he created an immortal empire from then on!

I will marry into your Feng clan!" ... Lin Xuan stood in the vast universe, looking at the battleships in the sky, slowly raising his left hand and making some virtual pressure.

The only person in the world who dares to mobilize me is Commander Lin Xuan! Look at me, drink!" … "Huh? Demon refining pot? Not bad, not bad. The Donghuang Bell is all good. Oh, it's going well... Haha——" System: "What's so good about this? A cosmic quantum decomposition cannon in this system is directly turned into ashes!"
