Wonder Boy in Monster Land/Round 7

The first door you see is a shop that sells boots.

The building past the market contains a miniboss that behaves like Death in the first round, although he is stronger and has extra minions to protect him. Defeat him to get a more powerful sword.

Enter the building to the right to activate a lift. Head back to the left and jump onto the elevator to rach the clouds. The second cloud you see has a bag of gold, as does the third.

Once you are past the bricks, you can jump down to reach the final southern island.

The Blue Knight has the key to the exit, and is locates to the right of the gate. He behaves similarly to the Red Knight.
