Full-Time Mage: the Jade Seal of the Country Recognizes Me as the Master

When he woke up, Qin Xuan, a student from the Department of Archeology, not only traveled through the world of full-time mage and became a little transparent of the Qin family in the imperial capital, but he also had an extra jade seal in his hand that no one could see - the imperial seal! Inside the jade seal, there is hidden the remnant soul of Li Si, who has been the same for thousands of years, bringing shocking news: the Holy Plane is glaring, the Dark Plane is staring at the abyss, multiple planes are about to collide, and the magical world is in danger! "You are destined to live a long and prosperous life after being ordered by heaven? Then I... Well, I will reluctantly bear the burden of saving the world." Jiuding controls mountains and rivers, Kongtong seals the palms of life and death, and Xuanyuan sword cuts through the void. The lost artifacts are scattered everywhere: hidden in the top-secret realm in the legend of "Peach Blossom Spring", the Chaka Salt Lake reflects the otherworldly generals' platform, the wizard whispers deep in the Amazon rainforest, the mastermind behind the Sahara desert emerges, the Antarctic emperor is frozen for thousands of miles... Is all this a coincidence or a shocking premeditation? What kind of characters are hidden under the glory of the Holy City? Qin Xuan: "Prime Minister Li, stop nagging, hand over the inheritance of Great Qin first... Oh no, help me find it first!" Li Si's residual soul: "Shu Zi! It's disrespectful to call me that! Also, find Ding first! Don't flirt with girls! Especially the ice type one!" Mu Ningxue: "..." (I always feel that someone is thinking about it, but I can't find any evidence)
