He Just Became Super 5 and Was Regarded as a Super Saiyan God by Beerus.

Ten years ago, Lu Yu traveled to the future time and space of the Dragon Ball world and awakened the mission system at the beginning. After unremitting training and systematic rewards, Lu Yu has exceeded his own limits in ten years and became the first Super Saiyan 5 warrior. And on this day, Beerus, the God of Destruction from the seventh universe, came to Earth because of a precognitive dream! "Yes, this guy is the Super Saiyan God of my dreams!" Looking at Rikuyu Beerus, who was dressed in silver-white hair and his silver hair hung straight down his waist, he said with certainty. It's just... Why is he stronger than in the prophetic dream? Lu Yu: "Super Saiyan God? Sorry, how can that so-called god be compared with Super Five?" … Super Dimension Son Goku, Vegeta: "What kind of transformation is this? He can't even defeat the Ultimate Intention Kung Fu!!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
