People can have no food for seven days, and they cannot have no water for three days.From a well and a first-class river, human beings can reproduce magnificent cities and endless countries.Water means survival, hope, and myriad possibilities.As long as thirteen silver coins are used, even the Son of God can betrayed.When something like silver is excavated from rock formations and soil, it is engraved with our greed.This is an era of hope and greed, an era of water and silver, an era of poison.
