I’m Building an Immortal Line of Defense in Another World

Who could have imagined that after staying up all night to beat the highest difficulty in a tower defense game, Lin Yue would be struck by lightning and flung into a medieval age of chaos before he could even uncork the celebratory champagne?

Luckily, the tower defense game came with him when he transmigrated, becoming his personal System.

No need to recruit craftsmen: towers rise from the ground. No need to stockpile provisions: a battle-hardened legion is ready at a moment’s notice.
