How can I reach the chest at the top of the Towers of Twin Dragons?

At the top of the Towers of Twin Dragons, there's a pair of chests at the very top.

map at the marked spot

After gaining Invert, I was able to get the first. But the second one I can't see a way to reach it.

the chest can be seen at the right look to the far right underneath the spikes

So far I haven't seen any breakable walls and this area appears to be completely inaccessible.

How do I get to this chest?

Solution 1:

You have to go near the left exit at the bottom of this zone ;
