From MC's Perspective:
The Black Raven Aircraft is flying in the night skies. I'm monitoring the terrain from the cockpit. Just as I was paying more attention to it.
I suddenly felt the mana in the surroundings have changed. It's a phenomenon related to the terrain. The next second, I stopped the black raven aircraft.
Swoosh!
Then I appeared outside. I looked down at the ground below. I could see a lot of buildings and lights. It reminds me of the cities down below.
The mana in the surroundings related to different types of earth magic. For a second, I thought of practising here.
Then I entered the Black Raven Aircraft and turned on the stealth mode. I appeared at the cabin and sat crosslegged on the ground.
I closed my eyes and started running the Gravity Ark Mental Method. As the time passed, the Gravity mana from the surroundings entered my body.
