Naruto: The Wind Calamity - Chapter 856: Hiruzen’s concern

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Jiang Mianmian crossed over,

Arrived in a different world full of giant dragons, became a nobleman disguised as a man, accepted the entrustment of the territory, and began to become a noble lord in a different world to make a fortune and start a petty bourgeois life.

Until one day, drinking water stuck between her teeth, two giant dragons rolled all the way, no, fought, and hit her door.

After a big move, the main city she worked so hard to upgrade and build was knocked back to its original form, and as compensation…

She only picked up a dragon egg? !

Ma Dan! You shitty dragon, are you demolishing the house? ! After dismantling, lay eggs!

Just like this, farming, hatching eggs and pulling the dragon cub until one day the dragon cub grows into a big black gold dragon. How does this dragon look so similar to the one that demolished her house back then? !

In the land of the Xia Kingdom, every human being is born with what is known as a ‘resonance’, either to a specific element or a powerful, mythical beast. Unfortunately, Li Luo was born with an incredibly rare condition known as a blank resonance – as the name suggests, he doesn’t have one! Normally, this would be utterly crippling, but at least he has the advantage of being the young master of the mighty House Loulan, one of the five Great Houses of Xia. Unfortunately, his parents, the powerful masters of House Loulan, have gone missing for many years, and the other Great Houses are beginning to eye their holdings quite hungrily. For that matter, plenty are also eyeing his talented, beautiful childhood friend and fiancee Jiang Qing’e, who has been leading House Loulan in his parents’ stead! Li Luo would much rather keep a low profile and wants to call off the engagement – but Jiang Qing’e has flatly refused. What’s a ‘useless young master’ to do?
