Capítulo 914: Chapter 391 Summoning Sky-base Breath, Dominating the Battlefield

```

Just as Jack Clark activated the Time-Space Summoning Altar, the Thunderflame Demon Dragon that had already flown out of the Ice Crystal Divine Palace and stood atop the ten thousand meter mountain peak suddenly let out a roar.

Roar!

The terrifying roar shook heaven and earth, as sonic booms thundered and generated rolling airwaves.

Behind the giant beast covered in thick scale armor, streaks of electricity sparkled between its dark-blue Dorsal Fins, turning into invisible electro-magnetic forces that spread across a hundred kilometers.

Boom!

The already cold and humid mountain peak's surroundings began to churn with clouds, as streaks of blue arcs thundered within them, and a raging wind howled, rotating around the summit of the mountain as its center.

Yi ya yi ya!?

The sudden change startled the purple little dragon on the head of the Thunderflame Demon Dragon, making it think an enemy had appeared.
