The night before he went down the mountain, Master said he would go and fix the leak and would be back in three days. Lin Du waited for three years.
He was picked up as a disciple by the old Taoist priest He Shouzhuo at the gate of the Taoist temple. He learned the skills of talismans, fortune-seeking, and requieming souls by the stove since he was a child. The master never came back, leaving only a notebook full of old events in the city. The second half of the notebook was missing, and the remaining page contained an address: Linjiang.
Lin Du entered Linjiang with this half notebook and became a delivery rider. During the day, he mingled in the traffic to grab orders, worrying about the rent like everyone else; late at night, something was wrong with the orders he delivered - the person who ordered the order disappeared thirty years ago; the delivery address was a ruin that had been demolished long ago; under the lunch box, there was a yellow paper written for the living person to read. Taking the order is a contract, so he has to come.
Master once said: If you can give away, don't accept; if you can persuade, don't fight. But some orders will come to you if you don't take them.
As each order was delivered, Lin Du gradually discovered that the last "leak" that the master had to fill before disappearing was under the city, and a pair of hands was digging it out again - some wanted to borrow the life of the entire street, some were releasing things underground in exchange for money, and some were waiting for the master's apprentice to walk into the trap.
After delivering this order, there is still another order. Every order brings me one step closer to Master.
