MTL - How Come These Monsters Have Health Bars - Chapter 41 confusing

[*Ding*

Jiang Shang travels through the Zongman world, but the first world is Fuyuki City?

Joan of Arc, who was not supposed to be alive, came to her door and begged him to participate in the Holy Grail War?

I thought it was the beginning of hell.

At the critical moment, the system awakens!

Just make choices, or rewrite the plot, to get amazing rewards!

“Ally with Joan, get: Top Heroic Spirit Template!”

“Choose to save Matou Sakura, get: Imaginary Space!”

“Summon a mad-ranked servant, get: the holy gun of the end!”

The Holy Grail War begins!

Facing the arrogant King of Heroes, Jiang Shang showed his magic whip under the dull gaze of all the heroes!

“Arrogant tyrants should be beaten constantly.”

“I won’t stop until you admit your mistake.”
