After the death of the Entropy Beast, a massive explosion occurred, scattering nearly all matter, yet some materials were left behind at the explosion site.
Due to Lu Chen's prior use of the Gravity Black Hole to attack the Entropy Beast, he accidentally observed the properties of the Entropy Beast Core's matter and felt that it somewhat resembled the Gravity Stone he possessed. Thus, after the explosion subsided, he promptly ordered the Earth Civilization's Cosmic Battleship to check the battlefield.
The other two civilizations within the Entropy Alliance also knew what might be left behind by the Entropy Beast. If they could acquire it and unlock the secrets of the unified force, they might have the chance to become a Level 4 Civilization, so they immediately dispatched their Cosmic Battleships to search the explosion site.
