  The soldiers arrived 500 meters from Colosseum. The 1st group of soldiers threw grenades at the dragons. Dragons got injured, but none of them died. Then, it was the dragons' turn. The female dragons spit poison and attacked with their tails. After that, the male finished the job by burning them with fire.

Mike shouted "No!!", and shouted "Launch the rockets and fire the cannons!", and the 2nd,3rd, and 4th launched the rockets and cannons. However, the male dragon just emit fire, and they went down. The 5th and 6th tried to flee, but was captured and became special dinner course for the dragons. So, that is how all the soldiers died.  3 years later,the hiding place of humans was disturbed by the high-pitched scream of a woman. " They are coming! The Powerful, blood-thirsty dragons!" The six soldiers who stayed 3 years ago tried to fight the dragons, but got defeated by overwhelming number of dragons. The last survivors threw grenades at the dragons, but they were out of grenades before long. They knelt at the dragons and cried "Save us!Mercy!", but dragons were not able to speak or understand English. Humans tried to run away desperately, but got caught in less than 10 seconds. The dragons killed the humans with venom and fire, and that's how the entire humanity became extinct.
