For his gunbai you could have it stockpile kinetic energy and release it sort of like how vibranium in marvel works, but the higher his rank the more efficient and the larger the stockpile, also maybe later on giving him the ability to convert said kinetic energy into spirit energy, as Einstein says, energy can't be destroyed, just converted. This will help him when faced off against an opponent that is far above his physical capabilities and his sharingan can barely keep up with.

He should also learn Kamui. It's a very versatile power and very fun, because the enemies don't have any idea of what is going on.

Some sharingan ability can be classified as self made spirit skill you could go for making susanoo a self made spirit skill and the tskuyomi Amaterasu as upgrade spirit skill like Mubais white tiger vajra transformation witch is his third spirit ring and the withe tiger devil god transformation witch is his fifth spirit skill witch they share the same attribute that he stacks for greater effect as for the gumbai wind and reflect are great idea if you look a how madara uses the gumbai to reflect attack defend himself uses to empower his fire attacks create gust of wind to blow away his enemies cut and bludgeon them so his first ring could be like king Carlos said as for the second ring sometimes that increases the strength or defence of it depends on how you want to do it

The rinnegan has the ability to give the user control over the 5 elements, you could give that to your ninth spiritual ring.
You can also make a spiritual beast join voluntarily

Nice chapter, I would love to see Xiao Wu', Tang San's and the rest of the Shrek Devils' reaction when they see how Madara trains. If it's anything close to how Might Guy and Rock Lee trained, then it must be absolutely insane.

It was pretty good, and I see that you fixed the entire format for your speech xD

Tang San was a bit out of character there at the end, but it was pretty funny so I suppose it fit well.

I am also curious about how the Sharingan will progress with the progression of spirit rank and rings. Will Madara also only focus on one spirit? Or will he find a way to level both in a way that will give him an advantage rather than just waiting until he hits Titled Douluo level.
