I Traveled Through Time and Became a Dragon

Xia Tian traveled through time and became a dragon, a bad-tempered dragon, a genius dragon in the history of the dragon clan. But fate played a huge joke on him... When he saw 30 days of health remaining on the system panel, he felt that his blood pressure was a little high and he couldn't help feeling dizzy. When he saw the main mission again, he suddenly woke up, his head didn't feel dizzy, his legs didn't hurt, and his waist... Wasn't sore anymore. He just couldn't help but want to... Run away. The person who installed the system is so wicked, even smoking. Xia Tian shouted, "It's too difficult for me."
