Roommates Travel Through Time to Search and Defeat? I Am the Demon King Protector!

From a certain day, people around Han Dong disappeared one after another. They traveled to an interstellar search and rescue game called "Hunting Star" and tried their best to survive. Every dangerous action was a bloody fight. However, Han Dong, the top player of "Hunter Star", has not been able to travel through time. He sat in the Internet cafe with mediocre equipment and became what people call the Demon King Protector. No one of his teammates under his protection has been injured or killed so far. Perhaps, before he travels through the "Hunting Star", the "Hunting Star" will come to this world first.
