Spare parts, and spare parts for the spare parts—that counted as one approach as well, but according to Senior Brother's advice, with this kind of method, I should have prepared more than ten of them. Unfortunately, I didn't have that much suitable raw material…Lei Jun let out a long sigh.
Ever since Lei Jun had reached the Sixth Heavenly Realm in his cultivation, he had rarely expended such a massive amount of mana as just now.
Firing three cannons at once nearly drained every bit of his mana.
Especially the metallic rails and Fine Gold Sword Pellets used to deal with Lin Likong—they had all been specially crafted by him, large-caliber…
The situation was complicated and time was tight, so besides drawing from his own Yin Yang Sacred Body and Breathing Soil Banner, Lei Jun activated a page of the Celestial Book again to circulate Spiritual Energy, letting Yin and Yang reinforce each other, doing his best to recover his depleted mana swiftly.
