He put a lunchbox into his delivery bag, and it disappeared.
The delivery bag could send something through only once a day, with a combined weight limit of twenty kilograms between the modern and ancient worlds. Living people couldn’t pass through either. Chen Li had to earn money making deliveries while sending food, water, medicine, and tools to his family in the ancient world.

In ninety days, the passage would reopen.
Before then, Chen Li had to keep his whole family fed and figure out how to get them home.
