I Was Reincarnated in a Modern Day Onmyoji Family

We got in Momi-san's car again and proceeded down the mountain road. The training site was located beyond the Goken family's mansion, further down the mountain.

"What is this?"

There was a vast flatland created by leveling the mountains.

It was much larger than I had imagined, as if it was designed for training for a large group of people.

And there were several huge blue tarps covering the vast land.

My father and Momi-san begin to carefully remove the blue tarp.

Momi-san finished folding the blue tarp and came back next to me, waiting near the car.

Momi-san explained everything to me without me having to ask.

"The type of formation that we draw directly on the ground is less effective when it gets wet. We had to put down blue tarps to keep them dry. The weather in the mountains is very unpredictable. Do you know that? It can be sunny like today, and then all of a sudden it starts raining."
