【National Destiny + Centenarian + System + Brain Hole + Science Fiction】 The National Destiny battlefield is opened on Blue Star. Each country will randomly select a player to enter the National Destiny battlefield. Players from various countries will guard a city to resist the attacks of monsters. For each wave of attacks, the players and their countries can get a lot of rewards! If the defense of the city fails, for every monster that enters the city, 10,000 identical monsters will appear in the country represented by the player! Chu Feng, who is over 100 years old, finally successfully activated the "Hundred Years System", which allows him to be one year younger every day and receive corresponding rewards! However, just after the system was activated, he was successfully selected and entered the National Destiny battlefield! On the first day, Chu Feng guarded the city gate alone and received an SSS-level evaluation, and the resources in the Dragon Country were +50%! On the fifth day, Chu Feng fought the beast tide alone, killing 72 lord-level monsters alone, and the life expectancy of all citizens of the Dragon Country was +20 years! The 100th day... When players from various countries were still guarding the city, Chu Feng had already been alone, killing into the dark restricted area, overturning the entire battlefield of all races, with 3,000 white hairs floating behind him! "I am willing to guard the country's borders with my 100-year-old body!" "Whoever offends China will be punished no matter how far away they are!"
