All People Travel Across the World to Purify All Realms

Negative energy surges, infecting countless living beings. The universe loses balance and reaches the edge of destruction. Li Zhengdao was fortunate enough to be spotted by the consciousness of the universe and became the savior. His mission was to eliminate infected bodies, purify the universe, and maintain balance. The workload is huge and one person can't finish it. What should I do? It doesn't matter, he can create a body that allows fellow earthlings to pass through the possession and become purifiers, traveling to various planets in the universe, upgrading and destroying infected bodies at the same time. The universe is very big, with civilizations of cultivating immortals, science and technology civilizations, magic civilizations... With mechas, battleships, spaceships, and magic, the Purifiers are omnipotent. Wherever they go, infected bodies have nowhere to hide.
