Lin Shijie is the most embarrassing loser in the mortal business world - his store closed down, he was in debt, and when he couldn't even make the last bowl of instant noodles, a golden light took him to the ninth heaven.
In the Lingxiao Palace, the Jade Emperor handed over an immortal casket: "The Heavenly Palace's Tianwen Treasury has accumulated thousands of years of destiny data, and manual calculations are full of errors and omissions. Many good people are robbed and evil people are free in the mortal world. You are specially awarded the 'Procurement Envoy of the Three Realms' to bring immortal magic to the mortal world to purchase computers to help digitize the Heavenly Palace and correct the order of the universe."
Since then, Lin Shijie has become the only "cross-border migrant worker" in the three worlds with the magic spell of the Immortal Family in his left hand and the purchase list in his right hand. Not only do they have to deal with difficult suppliers and debt-collecting creditors in the mortal world, use the shrinking technique to catch up on contracts, use the invisibility method to check accounts, and settle the mess one by one; they also have to go back and forth to the heavenly palace to debug equipment, reconnect the wrongly judged red line of marriage, and replenish the mistakenly deducted fortune value back to the accounts of good people.
When the computer screen lights up, the joys and sorrows of the mortal world flow clearly in the data. The once failed businessman is holding the key to correcting the fate of the three realms in the most unexpected way.
