Which one did Qin Shihuang choose for the old man who lit the lamp?

I met an old man with a lamp on the bridge. He will ask you what to give up, choose to give up your position, and you can get the heart lamp and cross the bridge of fairyland ahead. Through the cave on the bridge, you finally found the Peach Blossom Garden. Go back to Zhaocun directly from the cave behind Taohuayuan hut, report to the village chief, and the task is completed.
