Breastfeeding late at night and taking care of the baby during the day, Lin Wan thought this was what life was all about, until she was bound by a mysterious system and became a "preparatory guardian" traveling across all realms.
She must travel through the dangerous film and television world to perform tasks every month - outwit a third party in "Only Thirty", struggle to survive in "The Legend of the Queen", and protect others in the zombie craze in "Train to Busan"... If the task is successful, she will receive realistic rewards: life-saving money, a shelter, and strange skills to help the poor family survive; if the task fails, misfortune will befall her beloved family.
On one side is the thrilling world of life and death, and on the other side is the milk powder, diapers, daily necessities, and daily necessities. Lin Wan clenched the weapon of self-protection with her left hand and patted the crying baby gently with her right hand. She fights for protection, and during time travels, she transforms from a tired and desperate housewife into a mentally tough warrior.
This is an extraordinary epic about an ordinary mother. Watch her struggle between the worlds to earn a future for her children, and to regain the light and strength that have been eroded by life for herself.
