Returning to Caution in the Last Days Makes Me Seem Invincible All the Way

Realistic Black Technology Explosive Soldier Flow Phobia of Insufficient Firepower When Chen Fan was reborn, he originally wanted to rely on the "prophecy" brought by the memory of his previous life. In this life, he had the upper hand, but found that the theory of "butterfly effect" had already targeted him. And the more you do, the greater the change in everything in the past. How could this allow him to face the scarlet alien race that had crushed hundreds of planes and launched an invasion of his world? Just relying on the national awakening, the lottery system that can only barely let the survivors see a glimmer of hope from beginning to end? Or is it the same as in the previous life, relying on the principle of being more cautious and cautious in everything, using cutting-edge materialistic technologies from multiple planes, and spiritual energy and elements to fight against unimaginable enemies such as the scarlet alien race, the resurrected ancient god, etc.? Chen Fan: Destroy it, I'm tired. World: Wait, I feel like I can still save it. PS: Are you tired of watching the apocalypse of zombies and catastrophic hoarding? Come on, let's increase the difficulty of survival. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
