Entering Another World with the Dragon Balls

After the protagonist traveled through time, a Dragon Jewel Book appeared on his body, from which he could redeem everything that had ever appeared in the Dragon Ball world, including various martial arts, moves, black technology, etc... Shenlong cannot be redeemed! But you can exchange for Dragon Balls, and you can summon a dragon by gathering seven of them. You can even exchange for Namek blood and make the Dragon Balls yourself. Haha, it's really hard to be invincible.
