The Strongest Delivery System

Fang Xiang brought a brick down on the head in front of him, then staggered to his feet. A sharp pain throbbed in the back of his head. He reached up to touch it and found his hand covered in blood.

Ding! You have accepted an order!

Damn it, who wants to make trouble for me? Did that lousy phone get smashed? Why did it accept an order on its own?

Wincing in pain, Fang Xiang picked up his phone and glanced at the screen: Buy a bottle of Zhenshiming eye drops and deliver it to Qi Tian Dasheng at Withered Pine Ravine within five minutes!

Successful completion reward: one Mighty Immortal Pill!

Failure penalty: Earth will be destroyed!
