Chapter 733: Preparing for the Lightning Tribulation

"It's right here." As soon as he reached above the entrance, he immediately struck the ground as hard as possible, destroying the ground and entering the tunnel.

Knowing that Alex was on the verge of a breakthrough, she immediately helped him floating as they descended to the ground gently. "Your foundation is rock-solid, and with the assistance of Undying Fire Body, you are getting a terrifying boost from this power… I have realized that it's not the power of quenching that is the main boost to your cultivation. Instead, it's the Spiritual Energy around. Have you noticed that the Spiritual Energy became denser as we killed more monsters?"

"Yeah." Alex gritted his teeth, answering Firia's question. He didn't forget to check around the area with his Spirit Eyes, not finding any suspicious energy around. "I think it's safe to break through here… I need to adjust that power and cultivate a little bit more before I can trigger Lightning Tribulation."
