Resurrection of Spiritual Energy: the Formation I Rubbed with My Hands to Defeat the Mecha

Three thousand years ago, I was the number one formation master in the world of immortality, and all things could enter the formation. Three thousand years later, I woke up and found that the world had entered the era of "psionic organs". The ancient method of cultivating immortals is gone, replaced by huge "psionic battleships", "rune mechas" and "spiritual guns". It looks grand and spectacular, but in fact it is extremely rough! In order to drive a mecha, they actually need to burn an entire spiritual vein? It takes three days and three nights to recharge their so-called "forbidden curse-level" main gun? Looking at this era of profligacy and inefficiency, I have an obsessive-compulsive disorder. "Who is that? Stop filling the furnace with spirit stones and carve a spirit gathering array for me!" "Who designed the spiritual power circuit of this mecha? Don't you know if it's short-circuited? Use the Five Elements cycle instead!" When foreigners invaded, the human race's psychic fleet was retreating steadily. I stood at the top of the city, threw a few copper coins casually, and set up the [Zhou Tian Xing Dou Formation]. That night, the stars fell and thousands of ships were wiped out. Only then did the world know that the most powerful weapon was not the mecha, but the formation.
