The Third Layer!

Ning Luo had no time to discuss the fusion of Heavenly Flames with Huo Zhi. Seeing that the two had both summoned their Heavenly Flames, he stepped forward a few paces and stopped before the crystal wall. In a deep voice, he said, "Stay close behind me. Don't fall behind!"

As his voice fell, the Heavenly Flames in Ning Luo's palm suddenly surged. Then, amid an earth-shaking dragon roar, they blazed fiercely. A purple-brown fire dragon shot out from the flames and slammed viciously into the thick crystal wall. Its sharp dragon claws tore through the surface, instantly blasting a huge crater into the crystal wall.

"Follow me!"

The fire dragon's tail was connected to Ning Luo's arm. With a fierce shout, he stomped hard on the ground and charged forward. Behind him, Gu Qingyang and the others followed closely.

"We should be able to break through the light barrier in another half hour," the silver-robed man said after pondering for a moment.

Gu Qingyang nodded slightly. Now, they could only hope that Ning Luo would hold on. A barrage of relentless bombardment continued, thunderous explosions ringing without end. Yet the atmosphere among the group was incredibly tense. Every time they saw Ning Luo absorb one Energy Core after another, their hearts jolted violently. This rate of consumption was simply too terrifying. Boom!

The fire dragon howled as it crashed heavily into the crystal wall. Crystal fragments flew in all directions, but Ning Luo's steps slowed slightly. In a low voice, he said, "I'm out of Energy Cores."

Hearing this, quite a few people's faces twitched. Gu Qingyang hesitated briefly before swiftly taking out a dazzling Energy Core and handing it to Ning Luo. "This is a nine-star Energy Core. We only have one."

"Not enough!"

"I have one too."
