I Picked Up a Cultiv

Lin Chen was done. After absorbing another 100 points of qi energy, his strength surged by several thousand kilograms! His realm had reached the fifth level of Tempering.,What the heck kind of cultivation technique is this!,I've heard of breakthroughs through sudden enlightenment, absorbing heaven and earth treasures, or even self-harm cultivation. But I've never seen anyone break through their cultivation level just by wildly scratching at the air!。
