After Lin Feng is brutally dumped by his girlfriend, he awakens a portal to another world.
He discovers that it leads to an apocalyptic world.
Even worse, it's crawling with countless zombies!
Huddled in a corner and trembling, Lin Feng realizes that on his own, he's as good as dead.
So Lin Feng turns the portal over to the state!
With the country's support, Lin Feng begins exploring the apocalyptic world to his heart's content!
To his surprise, this world has technology far more advanced than Huaxia's!
With resources from the other world, Huaxia's technology advances by leaps and bounds, changing by the day!
Huaxia becomes the world's unrivaled superpower!
The apocalyptic world, too, becomes Huaxia's backyard: come and go as it pleases.
Then Lin Feng discovers that the portal doesn't just lead to the apocalyptic world.
It can also take him to cultivation worlds, fantasy worlds, high-martial worlds, and more!
With Huaxia backing him, Lin Feng gradually conquers every world!
Gazing at the countless other worlds, Lin Feng says slowly:
“Fine wine in a luminous cup at night, you and your bunker can take to the sky!”
“Laugh not at me drunk upon the battlefield, behold the wheeled self-propelled rocket launcher!”
“All fear stems from insufficient firepower!”
“If you have a problem, take it up with my nuclear warhead!”
“We in the British Empire once thought we'd conquered time. Now we realize we only conquered time zones, while Huaxia defined the era long ago!”
Uncle Sam: “We once thought we could bend the world's rules to our will, until we saw the ones who make the rules in the East.”
The little neighbor: “We once used aircraft carriers to set the rules of the world, until we saw Huaxia... Big brother! From now on, you set the rules of the galaxy!”
Good, keep it up. No obvious flaws.
It's well written and very good.
