Shen Gongbao: My Senior Brother Is Way Too Driven

Zhou Qing transmigrates into the Investiture of the Gods world as a green bamboo plant. He becomes a disciple of Shen Zhengdao and the senior fellow apprentice of the young Shen Gongbao.

The demon race is weak and treated like ants and weeds, fit only to be made into pills!

Fortunately, Zhou Qing awakens a proficiency panel. Once his proficiency is maxed out, his techniques transform into extraordinary arts:

Breathing Technique → Heaven-Swallowing Earth-Devouring Scripture

Fire Control Technique → Great Sun World-Burning, World-Purifying Divine Flame

Heavenly Dipper Steps → Wandering the Void Cosmos

…

Many years later,

Shen Zhengdao: “Leopard, if only you were half as disciplined as your senior fellow apprentice Zhou Qing, why would you have any trouble safely surviving your tribulation?”

Shen Gongbao nods in agreement, while shrieking inwardly: Good grief, you old man! You call someone who crafts time treasures just to get twelve extra hours of meditation every day, tastes every herb to forge an indestructible poison body, swallows tribulation lightning to strengthen his guts, and jumps into lava to temper his physique… disciplined???

Zhou Qing: “Ah, the prejudice in people's hearts is a mountain…”
