The World Was Reshaped and I Started a Magical Adventure

Overnight, the world changed. Various geological and climatic disasters occurred frequently. Countless alien continents descended on the earth. The blue planet was shattered and reshaped into a chaotic world. Countless civilizations shared the space. The civilization knockout competition officially began. But on the day the earth was reshaped, I got the system! Contest rules: Each civilization selects seven people to participate in the civilization knockout competition. The winning civilization will randomly descend on the habitable zone with its territory, and the remaining civilizations will randomly descend on the world, possibly in the magma sea, or in a void without oxygen. All civilizations can only be forced to fight for the right to survive.
