God of Thunder

The Tree was located in a lifeless desert so nothing for many kilometers around would prevent it from creating new Constructs and growing energy crystals. 

More accurately, it was the other cities that were protected from the Tree. Since like any Tree, this one had roots, and they were massive, spreading across most of the desert.

Though it was partially made of metal, the Tree was possibly the tallest plant of all the worlds, even in Plant World, there were no trees as massive as this one.

"Hehehehe, not bad." Alucard smirked as a long flash from Liang's sweep traveled across the desert.

Then, the desert split in two as the slash quickly reached the barrier around the Tree.

Tremble. Tremble. Tremble.

Several layers of the barrier were easily destroyed, but the more powerful ones were still able to stop Liang's attack.

"Shit... It was just an amplified sweep, wasn't it?" Marlis muttered in disbelief.
