What is the big bubble and force field that surrounds Tatarasuna?
Backstory, Shogunate of Inazuma is currently is at war with Sangonomiya Resistance. When at war the troop needs powerful weapons and munitions. The best current material for making weapons in Inazuma is high-quality Jade Steel. The Jade steel can later be processed into making a very strong and sharp blade.
As the war goes on Shogunate needs much Jade Steel to be produced as many as possible. So Shogunate contracted the scientists from Fountaine to make a powerful Forge and Furnace to produce a large amount of Jade Steel. The name of Forge is Mikage Furnace. Mikage furnace needs a large amount of energy to operate. Fortunately for Shogunate, The previous Electro Archon slew the Orobaxi.
