Second Plan.
It refers to.
Penetrating hundreds of light-years into the "Cosmic Void," then initiating a Space-Time Retrospect to go back 870,000 years and firing a high-level "Akanon Light Energy Main Cannon" towards the "Nia Star System," so that over time, its power gradually increases until it reaches the "Nia Star System."
Delivering a devastating blow to the Nia Star System.
This is precisely the Foundation Level Killing Weapon of a Fourth-level Civilization.
Although it consumes resources quickly, in a war of life and death for a civilization, resources are no longer a concern.
This method does not require a wormhole to reach the Nia Star System directly; it is a long-distance, cross-time-space attack. By the time human civilization detects it, the attack is already about to arrive or has already impacted the past timeline.
They cannot achieve precise targeting for now; there is only a general timeline, and the exact arrival time is unknown.
