Prehistoric: at the Beginning, Guang Chengzi Opened a Blind Box

Lu Yu traveled through the prehistoric times, became a disciple of Jiejiao, and obtained the Blind Box Mall. After I opened hundreds of thousands of blind boxes but nothing good came out, I gave up completely and started selling blind boxes! The first blind box was sold to Guang Chengzi. [Ding, good news, congratulations to Guangchengzi for opening the holy blind box and winning a top-notch innate spiritual treasure Fantian Seal. Guangchengzi: "Thank you, senior, thank you very much, senior." Lu Yu: "... One shot into the soul?" Nuwa looked at Buzhou Mountain: "Buzhou Mountain is not broken, why did the Heavenly Seal appear?" Taishang Taoist: "Second brother, how did you get the Fantian Seal?" Tongtian: "Second brother... Fantianyin?" Yuan Yuan looked at Buzhou Shan: "... I really want to practice, but I don't have the materials!" Lu Yu: "Humph, damn Ou Huang... Your name is Zhao Gongming, right? Want to try a blind box?" [Ding, good news, congratulations to Zhao Gongming for opening the Immortal Level Blind Box and receiving a Yuanhui True Immortal Mana. Zhao Gongming: "Is there really something? Thank you, senior." Lu Yu: "... Can the Immortal Blind Box produce true Immortal mana?"
