In the year 2031 of the Earth calendar, peace has enveloped the planet for more than ten years. Sun Wutian's son, Sun Xiaowu, a four-year-old boy with dual blood of Saiyans and Earthlings, grew up quietly in the greenhouse. He inherited the talent of his grandfather Sun Wukong and the gentleness of his father Sun Wuten, but in an accident, he awakened the ancient blood power of the Saiyans - a more primitive and mysterious energy that is different from the Super Saiyans.
When the mysterious cosmic gene reapers invade the earth with the intention of collecting the genes of the strongest warriors, the guardians of the earth gather again. But this time, the purple force field suppressed the power of all the warriors. In the desperate situation, the star bloodline in Sun Xiaowu's body unexpectedly awakened, and the golden flame ignited, breaking the deadlock.
However, this is only the beginning of the storm. The emergence of "primitive species" attracted more greedy eyes from the depths of the universe. On one side is the call and control of the ancient power in his bloodline, on the other side are the crises and powerful enemies that are coming one after another. Under the guidance of his father Sun Wutian, uncle Trunks and other seniors, Sun Xiaowu embarks on an unprecedented path of practice. What he has to face is not only the external enemy, but also the truth of his own power and the full weight of the word "guard".
This is the intersection of old and new eras, the continuation of the blood legend, and the story of how a child grows into a true warrior.
