Traveling to ancient times, Su Yunnian's ultimate goal is only to go home! Treating the princes as power banks, swindling token pledges and absorbing dragon breath, she just counts on the immortal peaches maturing to run away in one click. Thinking the third prince was just a discarded, unfavored good-for-nothing, who knew he would be the forbearing and scheming future emperor. Gathering the immortal peaches and about to escape, a system bug knocks her right back to square one. She puts on an act to humor him in seizing the empire, but after life and death, when the passage home opens once more, should she choose air conditioning and Wi-Fi, or the mad emperor willing to lavish the realm upon her?
