Resurrection of Spiritual Energy: Summon the Fourth Natural Disaster at the Beginning

Traveling to a parallel world where spiritual energy is revived, I encounter cruel beasts attacking the city as soon as I arrive. Once the city is destroyed, everyone will surely die. At this moment, Chen Yun suddenly bound to the summoning system. "Ding! Congratulations to the host for successfully summoning the Fourth Scourge Legion and completing the novice mission!" "Task Reward: Natural Disaster Level War Fortress and Supporting Facilities Construction Drawings and Materials" "Ding! Congratulations to the host for completing the task of defending the city. The maximum number of summons has been increased to one million people!" "Ding! Congratulations to the host for pushing back the ferocious beast's lair and being rewarded with a starry sky gate." Chen Yun led the undead army behind him, getting stronger and stronger as he fought, and finally pushed back the beast's lair and conquered the heavens! The name of the legion is: The fourth disaster! PS: A new book from an experienced driver, with perfect settings and 10,000+ updates per day, so you're done!
