I Have An Impenetrable Fortress

Zhang Dongyun passed through with an invincible city system.

As the city owner, as long as he is within the range of Invincible City, he is invincible.

No existence can harm Zhang Dongyun, and he can dominate the life and death of all the creatures in the city.

Moreover, the city will continue to upgrade and expand.

One city covers one country, one city encompasses one world, until one city encompasses all heavens and all worlds…

From then on, this world ushered in its own sole supreme, supreme ruler, the father of all people, forever God.
