Recover unidentified free space after erase

I am having problem dealing with this situation: after I deleted a system that I don't want via eraseVolume, I don't have the access to this 119.4 GB space below. I have no idea how to recover it, even with disk drill. Now all I want it to be is at where the Macintosh HD is at and make it a part of the main partition. I have the diskutil list output below and the sudo gpt -r show disk0 output.
