Su Wen traveled by car with his parents when he was a child. His father had a car accident while driving, and his parents were killed in the car accident. Su Wen grew up with his grandparents.
The grown-up Su Wen and his classmates went to a well-known noodle shop to eat noodles. The noodle shop owner is called Ha Na, and her craftsmanship is extraordinary. Customers who have eaten the noodles she made will often come back to patronize them.
Su Wen and his classmates came to line up outside the noodle shop. There were too many people coming to eat noodles. The shop was full, and the people in line had to wait for a long time to eat noodles.
Ha Na received a message from Brother Tie Zhong, and quickly closed the sub-noodle shop with her friends. The customers who were queuing expressed their dissatisfaction when they saw that Ha Na suddenly closed the store and stopped business. Ha-neul was out in a hurry and didn't have time to explain to the customers.
Tiezhong found the fleeing man in black, and quickly contacted Ha Na and the others. Ha Neul and her partner have super powers, and some of them are different from ordinary people. The man in black also has super powers, he can jump from the top of two buildings that are very wide apart.
Ha-neul chased up to the roof and saw the man in black jump to the opposite roof. It is impossible for ordinary people to have amazing jumping power, so Ha Na also jumped over from the roof and continued to chase the man in black.
The man in black appeared behind Ha Neul and guessed that Ha Neul was not a police officer. Ha-neul turned to fight with the man in black. The man in black had amazing arm strength and knocked Ha-na to the ground. Ha Neul's partner rushed over and was also knocked to the ground by the man in black. Ha Na stood up from the ground and attacked the man in black. She joined forces with her partner, and they were still no match for the man in black.
The man in black fled into a construction site and encountered Tiezhong. The two fought fiercely, Tie Zhong died in the hands of the man in black, and his soul flew into the air. Ha Na rushed over, and the man in black had left.
Ha-neul burst into tears when she saw the blood in the iron die on the ground.
The soul in the iron walked through the city and got into Su Wen's body. Su Wen fell to the ground and woke up amidst the shouts of his companions. Recalling the scene when he passed out before, Su Wen groaned in his heart.
Su Wen returned home and celebrated his birthday accompanied by his grandparents. Before going to bed at night, Su Wen went to the toilet and washed his palms. He found that small black holes appeared in several fingers. No matter how he cleaned, the black holes could not be washed away.
The next day, Su Wen went to school, and Ha Na led Su Wen into the car and returned to the noodle shop. Under the guidance of Ha Na and her party, Su Wen entered the intersection of Yin and Yang, and the messenger of the gods, Wigan, fell in love with Su Wen and reminded Su Wen that he could specifically arrest evil spirits.
Su Wen was reluctant to catch the devil, and Wigan reminded him to meet again next week. After Su Wen woke up, he told Ha Na and the others about his journey into the world of Yin and Yang. Before the meeting next week, Su Wen went to school to help a fellow student get ahead and deal with a few bad students.
