Reappeared
The dragon released another magma ball toward the World Tree while the latter used its branches to catch it.
As expected, the magma melted and burned the branches, but due to the World Tree's Magic Power, the branches withstood the heat for a moment and took that chance to throw it away.
"There is nothing good that will happen if we fight here, Dragon." The World Tree was frustrated, knowing he couldn't escape. "If we continue fighting like this, it's the same as playing in the human's hands. Even if you defeat me, you will still die because he'll appear and kill the injured you."
The World Tree's words touched the essence of Theo's plan. However, the dragon didn't seem to buy it as he was completely unaware of Theo's wickedness.
The dragon kept attacking the World Tree, not caring about Theo anymore. In fact, it would be easier if Theo just came out after the World Tree died. He had enough confidence he would be able to escape from Theo.
