I Have an Invincible City

This is a world where cultivators can soar through the skies, burrow through the earth, move mountains, and fill seas.

In a dilapidated cottage, village boy Lin Yan obtains the Invincible City System, and from then on begins his path to invincibility!

Invincible House, Invincible Village, Invincible Town, Invincible City...

As long as he is within his invincible territory, he is invincible beneath the heavens!

Faced with the armies of the Ten Great Sects of the Myriad Laws Domain, who have come to lay siege to him, Lin Yan remains unfazed and says calmly,

"Those who attack my city shall be put to death!"
