Graduate Yang Jian signed a life-and-death contract to guard Candeng's ancient house in order to pay for his mother's surgery. The ancient house is a parallel secret realm where ferocious beasts are suppressed, and the sand table in the house is related to the safety of Jiangcheng. The seal was loosened and the ferocious beast damaged the sand table, causing disaster. He relied on cultural relic restoration skills to repair the sand table. Yang Jian has the power of devouring and can reproduce the ability of strange beasts. He later joined the Demon Suppression Division, met Cheng Nian, and killed the nine-tailed fox. The former housekeeper, Wang Laosan, took Qiongqi to take revenge on Jiangcheng, and Yang Jian's grandfather and grandmother died. Yang Jian fused the power of the divine beast to devour Qiongqi and defeated Wang Laosan. When the other party was about to reveal the Zhongzhou sacrifice plan, he was silenced by a mysterious golden arrow. Yang Jian held a red umbrella and shouldered the heavy responsibility of guarding Jiangcheng.
