MTL - Marshal, She Has Seven Appearances a Week - Chapter 4 you won't really

The story about a family's struggle to ensure that, above all else, their youngest escapes from the mines where he was born into slavery. Follow Alistar as he struggles through terror and tragedy, embarking on a road to discover himself and his heritage.

A massive underground labyrinth awaits in an alternate world of swords and magic. With a game-like system much more familiar than spells and magic circles, Beatrice has managed her magic and risen to the position of “strongest”, but she still has her worries.

“Bghohhh!! Bshrrrr…mumble mumble…”

“B-Boo Boo! Stop! Stooooooop!! I’ll…I’ll be crushed!? I-is my, ah, love being tested!?”

Who is the legendary man named Boo Boo who, just by taking a nap, can overpower the Level Cap Holy Swordswoman? A thousand meter dragons and a proud elf girl will also show up, so what exactly is going to happen with these residents of another world!?

The servant looked at the grieving princess. “Your Highness, the Regent Prince sent your scholar fiancé to the Western Butcher’s daughter!” 

The princess gritted her teeth, speaking to her servant that it matters not as she has other suitors in line. Many days later, much to her dismay, the servant ran in a hurry. “Your Highness, the Regent Prince expressed his intention of becoming your suitor! All other men in line were sold to Gou Lan Red District!”

The princess was distressed. She said to her servant it matters not. She’ll soon be married to Prince Fuma. Then the uneventful came. The servant once more ran to her, almost tripping in the process. “Your Highness, Prince Fuma was imprisoned at home! Meanwhile, there’s a red sedan chair waiting at your residence for your marriage! It was led by the Regent Prince!

The princess was stunned. For a day such as this to come, it seemed impossible. This nothing but a sad story of a female boss crossing back in time to hold the thick thighs of the big boss. But while raising him, she was eaten in the process.

“I beg you, please teach me how to pick up female angels!!!”
Pleaded the twelve-winged angel.

“Teacher!! How can I fool more people into my sect?”
Asked a devil in the devil world.

“Do you know how to save the family cat that died last night?”
Someone in the sky is too embarrassed and asks me quietly.

“All the angel, all the big deity, please I am not God, I am really just a summoner….”
I said painfully.

This is the story of a poor boy and how he becomes the greatest summoner who dominates the six worlds because of an accidental acquisition of Dimension.
