Zhou Wen's Chaos Egg had been put to the test. It didn't explode back when it was used as a ping pong ball between Calamity-grade existences.
However, the sword beam from Perfect Sword Immortal was truly indomitable. The might of the strike caused many solid Essence Energy Crystals to form in the Chaos Egg, but it failed to shatter it.
At the bottom of the deep pit, Zhou Wen unsummoned the Chaos Egg and summoned the Earth Elemental Beast. He wanted to use its Earth Escape powers to escape.
However, the Earth Elemental Beast didn't escape far before it suddenly let out a tragic cry. Its body seemed to have been penetrated by invisible swords.
Zhou Wen was alarmed as he immediately knew that it wasn't safe underground. He was still in the Calamity Zone, so the Earth Elemental Beast probably couldn't escape.
However, this allowed Zhou Wen to roughly determine the range of Perfect Sword Immortal's domain and gain some confidence.
