The hindmost stride.

There was the same sign as they had but in a large size.

There was an instruction written"Do the spell 'Threshold openito'Holding each other's hand."

"Threshold openito!!!"

They casted the spell and the door opened.

It led directly to the last chamber of the temple.

"Look,the infinity stone!!!It's there."Saying this Sia was going to move but then Anthony stopped her holding her hand.

"Wait!!Look down there are few structures drawn and there are bow with arrows in the corner probably there is some difficulty here."Anthony said.

He threw a stone near him to the circle and arrows started coming continuously.

"How do we get there then!!!"Sia said.

"No idea.Let's search if there is some solution."Anthony said.

Sia stepped on something and was about to fall down but Anthony saved her.

"Look this stone looks exactly fit for that space in the structure.Let's try fitting it there."Sia said.

Anthony nodded and they put it in the structure there.

The stone dissappeared and a switch came up.

They clicked it.

"Let's try it again!!"Anthony said and threw thenext stone.

And...

The arrow didn't show up.

Feeling calm they moved to the infinity stone.

"Anthony pick it up I will bring that solution here."Saying this Sia went to take the solution which could change the infinity stone into an evil defeating stone.

"So...You finally picked it up!!!Perfect hand it to me!!"Grandfather aka the royal minister said.
