I Handed Over a Two-Way Portal from the Start and Built a Ten-Thousand-Mile Dragon City

Lin Yi obtained a twin-world portal that let him travel between two worlds. As a veteran web-novel reader, he decided to hand it over to the authorities!

Just then, a Divine Choice appeared.

Choice 1: Become a star traveler! Reward: Zerg genes, immunity to any hostile environment, and the freedom to wander the universe.

Choice 2: Change history and fight to the death! Reward: blueprints for a ten-thousand-mile Dragon Wall, a comprehensive upgrade to his physical abilities, and the power to fight the Zerg alongside humanity.

Lin Yi chose option 2.

The Ten-Thousand-Mile Dragon Wall project began, to hold back the Zerg.

The electromagnetic railgun project began, to annihilate the riffraff.

The Xuanyuan mecha project began, to strike at aerial targets.

The Tiangong mothership project began, to wage war in outer space and take out the Zerg fleet.

The moment the Ten-Thousand-Mile Dragon Wall was built, the moment the electromagnetic railgun fired, the moment the Tiangong mothership took off...

The truth is, anything outside the Tiangong mothership's range doesn't matter.

From then on, the Zerg and humanity switched roles, and hunter and prey exchanged places.

Standing aboard the Tiangong mothership and gazing at the endless Zerg fleet, Lin Yi said in a grave voice, "From this day forth, the tables have turned."
