If he were a bit more hot-tempered, he might have resorted to violence. But before taking action, he would have to consider whether it was worth it—to clash over some Crystal Coins or suffer losses and make a mortal enemy of an Awakener certainly wasn't wise... Of course, if an Awakener consistently broke contracts, then perhaps no one would want to work with him in the future.
So for these Awakeners, fulfilling contracts essentially depended on their conscience.
Still, Wang Tao took the contract seriously and inspected it carefully—he was quite conscientious by nature.
Moreover, this was probably the highest-paying job he had ever gotten in his life.
The purchasing power of Crystal Coins at Changhe Base could be simply understood to be ten times what it was before the apocalypse. His monthly salary of over forty thousand Crystal Coins, if converted to the pre-apocalypse standard, would be over four hundred thousand a month—certainly a high income.
