In Konoha, I Directly Summon the Holy Lord

Xia Yan transmigrates into the world of Hokage, and into the Uchiha Clan, which is on the verge of being wiped out. Just as he's racking his brains over how to deal with the clan's impending extermination, he unexpectedly awakens the Summoning Evolution System:

Ordinary frog sealed. Wind Demon Xiao Feng's evolution complete.

Ordinary water snake sealed. Water Demon Basha's evolution complete.

Madara Uchiha's hair sealed. Fire Demon Shenzhu's evolution complete.

During the Shinobi World War many years later, Madara Uchiha looks at the Uchiha descendant with the Eight Demons standing behind him, then can't help turning to Obito:

"Hey, what kind of Susanoo is that supposed to be?"
