You want to get to level 5 invention immediately. Take any extra barrows pieces you get to this place here.

Scrap barrows items obtained from barrows to gain invention expierence do this untill you are lvl 5 invention.

Base Solrot

Right next to Scrap-man is the invention workbench

Clicking it you can see all the tiers of Solrot gear available, and a summary of whats required to upgrade each piece.

Clicking in on any piece of gear we can see which ITEMS are required.

Ensouled Lanterns will come from killing the Solrot boss, which can be found inside the Barrows Crypt here.

You will need an enchanted key from barrows chests to get a 5 minute respawnable instance of Solrot the Sinful. It will require prayer, he attacks with multiple styles.

Strategy

My strategy would be to keep grinding zones and scrap ingredients at Yes-man.

When you are at the unknown underworld zone i would keep staying as long as you could at each unknown monster to get as much ingredients to scrap for invention exp.

This would be the fastest way to get 99 invention.
