What is the Two-Dimensional Foil?
It's a weapon of extremely powerful force, so powerful that it can effortlessly destroy an entire galaxy and civilization, to the extent that even the universe itself gradually perishes under the erosion of this weapon.
If such a weapon really exists, then unless cultivators wield a weapon that controls the law of causality, there is basically no possibility of resistance.
So when the Heavenly Dao says that technological civilization is superior to Immortal Dao civilization, in a sense, it's not wrong... if humanity can indeed develop the Two-Dimensional Foil.
But where did the Two-Dimensional Foil come from?
Lin Yuan knows, it's from a book...
This kind of weapon has never appeared in the real world.
So how does the Heavenly Dao know the name of this weapon that has never been created?
A terrifying thought suddenly crossed Lin Yuan's mind.
