Miraculous Ladder: Destroy One of the Divine Realms at the Beginning

A magical ladder has descended on the world, and all countries have to fight in the ladder. The winner will survive, and the loser will suffer natural disasters for the country. All the gods of Yao and Xia lost contact a thousand years ago, and history also had a gap in inheritance at that time. Thousands of years later, no one knows the gods and history of Yao and Xia. In the Ladder of Miracles, Yao Xia had no god to summon, so there was a Achilles' heel in the Ladder of the Five Realms. God's realm, Taixu, mortal world, demon spirits, foreign races, the other four realms all have the power to fight. Only the "God Realm" is empty. As long as the spiritual summoner is drawn to the battlefield of this world's ladder, he can only die. From then on, every country in the world had a 20% chance of winning as long as they were drawn to fight against Yao Xia. All this changed when the spiritual summoner Xiao Nanyu was reborn...
