After a long period of training and getting along, I have an inexplicable affection for He. One day, Fan Tian Lei was leading the recruits in training when the radio rang. He asked Fan Tian Lei to choose the best team to perform an urgent task. The novices are all eager to try. Fan Tian Lei decided to take them on a mission, and at the same time, he also took Tang Xinyi with him. In the briefing room, He Zhijun, the battalion chief, introduced the octopus and the target of this operation. The operation code is a black box. This time, we will make use of the beauty of Tang Xinyi to conduct a personal survey on octopus to get information. He and Chen Guang and his party questioned this action and thought it was against the regulations, but Fan Tian Lei still put all his eggs in one basket. The black fist was completely annihilated, and everyone realized that it was another test after the end. However, in this test, Chen Guang and Tang Xinyi were alienated.

The "red blood cell" team was finally established, with five members, and took a week off after the Black Boxing operation. After the holiday, they actually faced the first formal challenge in their lives: the confrontation with the international killer organization headed by Scorpion. The first encounter with Scorpion ended in failure because undercover Hong fell in love with Scorpion, but it was also because of this action that Scorpion's subordinates took refuge in the police and worked undercover beside Scorpion.

In a mission, Tang Xinyi was poisoned by poison gas and became a vegetable! But He Chengguang didn't give up on her. He thought about changing jobs to take care of her, but he was stopped! In the finale, He Chengguang successfully killed the scorpion. After Tang Xinyi brought the ring He Chengguang gave her, her finger suddenly moved, and the story was over!

The end result is that the scorpion was killed, and the tea committed suicide. The Golden Eagle was killed by a Grenade to save his ex-wife, and the immortal bird was killed by the class assistant after becoming the undercover of the police. Tang Xinyi woke up and lived a happy life with him!
