What Lin Chen spoke was a harsh reality.
Even though my life is controlled by you, if I just instantly killed you in a fraction of a second, wouldn't that make you unable to manipulate me? Wouldn't everything be okay then?
Even though you hold my True Soul in your hands and can kill me with a mere thought, what happens if you don't even get a chance to think before you're killed instantly?
Nangong Night had considered this tactic. After all, he was at the second realm of the Great Luo, whereas Lin Chen was only at the Fairy stage. His strength, if used for a surprise attack, could kill a Fairy in an instant, couldn't it?
However, the more he came to understand, especially after witnessing the power of the Linglong Tower and the tactics of Lin Chen, Nangong Night completely abandoned this idea.
Lin Chen had the audacity to promise himself, instead of forcing Nangong Night to submit to his wife or disciples. This meant he must have a firm grip on the situation.
