Ever since experiencing Jiang Ke's jailbreak, and later on the incident with Cheng Lingfei, Zhao Yu had unconsciously become interested in the type of tasers they had used.
First of all, the tasers had been mounted to their wrists, hidden in their sleeves. This made them very concealed.
Second, when shooting you only needed to raise your wrists, like Spiderman shooting his webs. Zhao Yu could shoot out electrified bullets that were able to achieve unexpected results.
Lastly, these electrified bullets were so powerful that as long as they touched the opponent, they would instantly lose their combat abilities but would not kill them.
Thus, to Zhao Yu, who often came in contact with danger while catching criminals, this taser was indeed the perfect weapon.
