The Strongest Mechanic in the World of Immortality

[Hot-blooded + Mecha + Cultivation + Time Travel + Funny + Technology + Military Series] In the world of cultivating immortals, have you ever thought that when you are fighting against the kingdom of God, everyone on the other side is riding a strange beast and holding a magic weapon in their hand, but your side only has tens of thousands of Tiger tanks, thousands of giant Titans, hundreds of combat aircraft, ten mechanized combat infantry divisions, five B26 fighter bomber groups, and one Gatling with blue fire per capita. Will you be afraid? When you besiege someone's sect, everyone on the other side is flying swords and holding sharp blades, but you can only stand on your Star Destroyer and watch your thousands of J-20 fighter jets sigh. Alas, we all convince others with virtue.
