[Kill decisively] [It's so easy to make money from dead people] Su Zang traveled to a world where spiritual energy was revived. Fortunately, there was a trading system around him. As long as you trade with ghosts, you can get system rewards and the wealth left behind by the dead. The results of the college entrance examination are out, and there are still two months of vacation before school starts. The next thing to do is naturally to work during the summer vacation to earn some pocket money. Other students were either working as waiters or delivering food or working in factories, but Su Zang was different. He only makes deals with ghosts and makes money from dead people! "Boss, I haven't kissed a woman on the mouth for a long time!" "Looking at how wretched you are, I have to add more money! After adding more money, I will cook Japanese, Korean, European and American food for you, and you will be able to enjoy it every day." "Boss, help me move the grave. When it gets windy and rainy in my place, the bones will almost disappear!" "It's easy to talk to! If the money is enough, I promise to move you to a beautiful place."
