Welcome to the Innocent World - Chapter 27: I am Nuclear

Son of a bitch! I just finished this godawful fantasy novel, and now I'm knee-deep in it – as David, the disgraced son of the Solarian Empire's top general! Talk about some twisted cosmic joke. But hold on a damn minute... maybe this isn't all bad. Armed with the knowledge of that trashy plot, I can become the ultimate shadow player, an overlord perhaps. Screw the damsel-in-distress harem too – it's time to pull the strings and become the real power behind the throne. This isekai might be a steaming pile, but I'm rewriting the ending with a little more... Debauchery (wink wink).

Childhood sweethearts.
The most popular person in school is my childhood sweetheart.

After transmigrating, medical expert Gu Qingxue became a widow with three small babies waiting to be fed.

Armed with a Miracle Doctor System, she used the needles in her hands to snatch people from the god of hell, raised the craziest children possible, and abused the scum of all scums!

But, no one could have expected her to accidentally provoke a famous war god from the frontier region!

The man had looks, money, and status. He pulled her back to his place to become his regent consort.

Gu Qingxue told him frankly that she was already married and had children, so it was a no! But then…

Who can tell her why all her children looked like him?!

Her second baby, Xiao Daimao, faced his father and said to everyone, “My mommy is very knowledgeable, so why would we need a father?!” Her third baby, Xiao Mian’ao, would boast whenever he saw people, “My mommy has a beautiful, sweet voice. It’s enough that I have my mommy!”

Only her eldest child was mature, remaining calm and unaffected. Then, her fourth child shouted, “Brother! Dad is climbing the walls again!”

Her eldest child, who had been unruffled a moment ago, picked up a big stick and rushed out immediately.

He would guard his mother till the end!
