Upon seeing the system prompt, Song Jian was perplexed. He only used his dagger to kill two first-level mutated zombies, and his skill level rose a level, saving him one skill point in the process.
After some thought, Song Jian realized that he had practiced his dagger fighting technique in the real world for several hours.
"Could it be," Song Jian wondered, "that exercising in the real world can also improve my skill proficiency in the game? And if I strengthen my body in the real world, will it enhance my physique in the game?"
This possibility was substantial, and Song Jian couldn't wait. He wanted to leave the game right away to verify this in the real world.
