Fiend-Star Lightning Sword!
A star suddenly appeared in Luo Cheng's eyes, and a terrifying aura surged out. His sword slashed out at the stone pillar.
The three Earth-Ranked genius were appalled to see Luo Cheng's sword somehow manage to send that terrifying stone pillar flying.
Those stone pillars were made of an unknown material that was shockingly hard and heavy. Anyone who was struck by them had been crushed to paste.
In fact, it was a stone pillar that had smashed apart the outer coffin, the outer coffin that had been so tough that even hammers had been unable to cause any damage to it.
Such a tremendous pillar had been sent flying by Luo Cheng's sword. But since Luo Cheng had knocked it back, it ended up impacting the other pillars, causing a chain reaction, and all the stone pillars quickly collapsed.
Once the stone pilars toppled, the ceiling was unable to endure anymore and completely collapsed.
