I Pioneered Scientific Magic - Chapter 431: The Holy City Trembles

One morning, after being bound to the system, MC started his routine of always being captured/ attacked by the ML.

It doesn’t matter if he transmigrated into the ML’s little brother (TN: Here I think brother disciple) or master or opponent, but in the end he is still forcibly taken by the ML.

After transmigrating to many worlds:

MC: Come out system!!! The heck?! Why do these MLs not love their female goddesses, but insist on doing it with me! Aaaaahh!!!

System: …. __(:3」∠)_ Don’t ask me, I also don’t know.

Opening his eyes he finds himself in the unfamiliar ceiling scene.

After going through the body's memories he finds that he transmigrated into a cultivation world.

But there is a problem;

Why is everything around him look like a flag that he is the young master who gets killed by the child of the plane a.k.a. the MC?

How would he implement his try not to die plan?

There was once a hero.

Unique black hair. Excellent eyes. Contrary to his delicate features, he who had abnormal strength was called the Otherworldy Hero.

At the hero’s long adventure (up to the point where his wooden sword that had been kindly granted to him by the king was replaced by the holy sword blessed by the holy maiden) he saved the prince that had been kidnapped by the demon king, and so the kingdom was swept by worry.

The hero’s strength that could fell the demon king was deemed too dangerous to leave unrestrained.

One advisor spoke up. Why not marry him to royalty?

The king thought that was a viable option. Family, to an alien from another world would be the best of chains. There was one problem. The king was abundantly blessed with sons and had princes galore, but not a single daughter.

Ho, and it wasn’t like I could marry off two boys.

At a burst of inspiration the king slapped his knee.

That was it!

You just had to turn a prince into a princess!

And so the hero ended up in a position to be marrying a man.

This story, is a tale of the aforementioned otherworldly hero, and his bride, the former-prince-now-princess and their ridiculously hilarious marriage.
