Awakening the Strongest Lightning Powers, I Dominate from the Start

[Lightning] + [System] + [Tang Dao] + [Warden] + [No Female Lead] + [Decisive Killing] + [Territory Building] (The rating has just come in, and it should keep rising...) Su Chen transmigrated into a high-martial world teeming with vicious beasts and has lived there for eighteen years. Naturally, no transmigrator would be complete without a System, but he'd been waiting for it to activate all this time! At last, it activated during his awakening ceremony. [Abnormal energy detected in Host. System activating.] The System not only granted him an S-rank lightning ability, but also gave him the chance to level it up by hunting monsters and keep growing stronger! There's just one problem: the protagonist's choice of fighting style seems a little off. Everyone else with lightning abilities keeps their distance and rains down attacks, or uses a spear. Su Chen insists on charging into close combat with a Tang Dao! Even the System can't take it anymore: Lightning users deal huge burst damage but are fragile. Why charge in with a blade? Are you tired of living? Su Chen gently brushed the blade and sneered. “What do you know? Casting spells from a distance is for cowards hiding in their shells. One slash at close range, one kill. That's what it means to be bold, cool, and badass!” Lightning accelerated him to the utmost, unleashing explosive power. A blue-striped wolf charged with a roar, and before the crisp sound of his Tang Dao leaving its sheath had faded... Violet lightning streaked across the sky. His blade flashed, and the wolf's head hit the ground. Su Chen sheathed his blade, not a drop of blood on his clothes. With this extreme, knife-edge style of killing, he carved his way up from a village-level border Warden to the Warden defending an entire national border! Years later, standing at the pinnacle of the Warden Bureau with the corpses of countless Beast Kings beneath his feet, he finally remarked: “So lightning and a Tang Dao are the path to invincibility!”
