Thunder Ninja Dragon Emperor

Long Chen traveled through time and became the orphan of Lei Ninja Village, Ryunosuke. Others: I want to practice hard! Ryunosuke: Sorry, the amount of chakra is tailed beast level, the five attributes are balanced, and the apprenticeship of Raikage is through the back door. He became a chuunin at the age of twelve, a jounin at the age of fourteen, and became a god in three battles. Personality: He looks cold but is actually sinister. He is good at ninjutsu fusion. He also has a bad taste and likes to prank bosses. Harem: Raikage's secretary, Kirigakure Queen, Tsunade's mother-in-law, Konan, Ye Cang... The goddesses are in a group, and everyone is chasing after them. Main plot: While collecting the harem, conducting scientific research, and by the way, the four wars were tied. Ryunosuke: "I just want to be quiet and strong, why does the world revolve around me?" All the heroines/friends: "Because you are so strong and so good!"
