What is the best to earn gold( star coupon)?

[Ildun]

The cost of leveling is so high, since I cannot lack of material to evolve or awaken, I have to depend on my level to beat main quest, is there anyway to earn money faster?

Leveling up the hero's level will be less and less helpful for improving your CP. You can try to upgrade equipment and elves, or unlock the God and the artifact. Or use some commander items in a combat.
