Even if they lose everything now, as long as they win the final battle, everything lost can be reclaimed anew.
Even using the words of Emperor Taizu, without these religious sects and noble families blocking the way, even if the battle smoke rises everywhere, it would be no big deal for me to once again wield a three-foot green blade and sweep across the universe, reclaiming the world all over again.
This is the confidence of a pioneer. He believes that without external influences, even if he has to start over, he can still win and become the ultimate victor.
Many powerhouses have such confidence. Although they value their foundations, they are not overly concerned about them, confident that even if they smash these bottles and jars, they can still acquire something better.
