A Century of Ascetic Cultivation, Better Than a Day of My Recharging

Zhang Xiao, a PhD in electrical engineering, transmigrates to another world with zero cultivation, zero background, and zero resources. But he discovers that spirit stones are essentially batteries. Others rely on talent for cultivation; he relies on physics. Others fight over spirit stones; he manufactures them. Others practice martial arts; he industrializes. When the cold-weapon battlefield is transformed into a spiritual energy arsenal, and when spiritual martial artist legions sweep across the battlefield, those once-arrogant enemies finally realize they are not facing a single cultivator, but the crushing force of an entire era. When the enemy descends, thinking they can easily trample the Yan Kingdom, they are met with a grand army of spiritual venerable realm soldiers sweeping the battlefield. Zhang Xiao stands atop the city wall: "It's time for the world order to change." — Description from novelcodex.org
