Pan Yue arranged for three people (Song Zhuowen, Tian Xiaojiang, and Ding Peng) to interrogate the acupuncture doctor Dr. Shi on the pretext of training new people. He judged that if there was an underground party, they would definitely use this opportunity to contact Dr. Shi. Song Zhuowen almost fell into the trap., fortunately, it was judged in time that this was a trap, and finally the trick was used without any flaws.

Tian Xiaojiang was quickly taken away by the Japanese, and Song Zhuowen's suspicion was lifted., and also gained further trust from Guan Xue.Guan Xue invited Song Zhuowen to eat at home. Although Zhuowen had not had time to complete the memory puzzle, he had to go.

Sure enough, at the dinner table, Guan Xue said mysteriously that the dish cooked today was Zhuo Wen's favorite dish. Song Zhuowen did not answer this question perfectly, and Guan Xue was surprised.

Song Zhuowen knew that similar problems would follow in the future.Song Zhuowen conveyed the news to Dr. Shi in the interrogation room that Dr. Shi's wife and children had been safely transferred. Dr. Shi was deeply comforted after learning the news. He knew that it would be difficult to get out of the Special Service Department alive. In order to avoid involving other comrades, he prepared toSacrificing himself, he told Song Zhuowen before he died that there might be another person (a man in a suit) who took the information at the train station. Song Zhuowen could only roughly recall the image of that person through his memories.

Episode 5

Song Zhuowen began to search for clues to find the person who might have obtained the information that day, a man in a suit. Pan Yue, the head of the Intelligence Unit of the Special Service Division, was also searching for clues to investigate. The two followed the clues and raced all the way to find them. They found them almost simultaneously..But Song Zhuowen was finally one step ahead and tracked down the traitor first, and shot him to death after negotiations failed.

He was injured and admitted to the hospital. Asano Daigo told Guan Xue that this killer may have been in many places many times.One of his assassins was an anti-Japanese activist nicknamed “Manchurian Robin Hood”.

Guan Xue suggested to Asano Daigo that he should release the news that Asano Daigo was going to be discharged from the hospital, so as to lure the anti-Japanese element to show up again and set up an ambush to arrest him. Asano Daigo agreed to this suggestion.Guan Xue also reported the film negatives to Asano Daigo, and Asano Daigo asked Guan Xue to show it to him quickly.

As expected, the assassin who had already disguised himself appeared again, preparing to snipe Asano Daigo from a nearby tall building.Just when Guan Xue and others locked the target and prepared to arrest, Song Zhuowen gave the assassin some hints through mirror reflection. After the assassin discovered that there was an ambush, he knew it was a trap, ended the operation early, and successfully left the scene.The Secret Service came up short.

Song Zhuowen felt that this assassin was somewhat familiar, and began to look for clues to analyze the assassin's whereabouts. Finally, he found an uninhabited villa late at night, and sure enough, the assassin was hiding here.

The Secret Service also quickly found this place based on Zhuo Wen's report. When they broke into the villa, they saw Song Zhuowen who had just been attacked and was in a panic. Song Zhuowen told them how he found this place, but it was a pity that the assassin escaped.Guan Xue didn't pursue the matter further, she just asked him not to act rashly and dangerously in the future.

Hu Bin expressed strong dissatisfaction with Song Zhuowen's unauthorized actions, complained that Song Zhuowen had done something bad, and blurted out all kinds of sarcastic remarks, but when he saw that Guan Xue had no other expression, he had to give up, but he once again asked to have a duel with Song Zhuowen..

Song Zhuowen, knowing that he could no longer avoid it, agreed this time.Early the next morning, the two began to compete on the street.To the surprise of everyone present, Song Zhuowen, who had previously seemed incompetent in martial arts, beat Hu Bin until he was unable to parry, and was finally stopped by everyone.

After investigation, the Secret Service found that the stall owner had met the assassin, Song Zhuowu.

Guan Xue took Song Zhuowen and others there. When Guan Xue asked the stall owner to describe the assassin's face and appearance, the stall owner subconsciously stared at Song Zhuowen, who was standing next to Guan Xue before he could dodge. Everyone also looked at him.Song Zhuowen couldn't help but break out in a cold sweat, but the stall owner's description was completely different from Zhuowen's.​

After returning home, the two brothers began to take stock of all the details of what happened. Song Zhuowu said that on the way back, a young man greeted him and seemed to know him. Song Zhuowen judged that this person was Guan Kai.Song Zhuowu had met Guan Kai when he was a child, but now he no longer recognizes him.Song Zhuowen remembered that if Guan Kai mentioned this matter after returning home, the brothers would reveal their secrets, because Zhuowen was with Guan Xue at that time.

Song Zhuowen went to find Guan Kai urgently. Unexpectedly, Guan Kai also didn't want Guan Xue to know his whereabouts because of some secret, and asked Song Zhuowen not to mention the matter. Song Zhuowen just agreed, and they agreed that the two of them would pretend they had never met.The consensus is that Zhuo Wen is also curious about what Guan Kai's secret is.Song Zhuowu decided to assassinate Guan Xue alone, but after shooting, he missed.

Another Japanese officer was shot dead in Harbin. Guan Xue realized that it might have been done by Guan Kai, because Guan Kai had a special pistol that happened to fire the kind of warhead that killed the Japanese.

Guan Xue returned home and asked Guan Kai to hand over the pistol. Guan Kai bit the pistol and lost it.Guan Xue was very angry but helpless.

Episode 12

Hu Bin came to Guan Kai's house early in the morning and forced Guan Kai to hand over the pistol and bullets.Then he brought the ballistic analysis report and told Guan Xue that it was not Guan Kai's pistol that fired the gun. Guan Xue felt relieved this time.​

The traitor described to her that he saw the pursuer, Song Zhuowu (who failed to leave the city).He came back), who looked like Puke, etc. Just as everyone was staring at Song Zhuowen, gunshots were heard on the phone.

When Guan Xue and others rushed to rescue the traitor, they arrived at the scene and found that the man had been killed and the murderer had already left.It turned out that fortunately Song Zhuowu returned in time and solved the traitor.

Lao Qian asked Song Zhuowen to find a way to send the liaison officer and the film out of the city immediately. However, at this time, the Secret Service had laid a dragnet at all exits in the city and set up numerous barriers. It was very difficult to send people out of the city.

After Song Zhuowen looked at Zhuowu for a while, he came up with a way. He took advantage of the loopholes in the shift change time of the checkpoint personnel, and finally asked Song Zhuowu to drive out of the city with the liaison officer and the film.

However, Cui Anping, the shift leader, discovered that the vehicles leaving the city did not return to the city on time. He discovered that something was fishy and did not change with the next shift.Because he discovered that there were two Song Zhuowen, one was in the city and the other was out of the city, he vaguely guessed that Song Zhuowen might have twin brothers.

Realizing that he was deceived, Guan Kai was in great pain, but he also thought that this might be an opportunity for relief. He got into Guan Xue's car and decided to die with his sister.

Song Zhuowen, who had been in the hospital, found that Guan Kai was very unusual today. At first, he followed and observed for a while but found nothing unusual. But in the end, from the look in Guan Kai's eyes and the words he said to him when he got in the car, he quickly flashed back and sorted out various clues from the past.Realized the bomb under Guan Xue's car.

Song Zhuowen's task was to contact him after he arrived in Harbin and hand him the tools needed to complete the task.But this man was timid in the face of battle and did not dare to go.

Song Zhuowen decided to go to Dongning in place of the special envoy, so he asked Guan Xue to quickly injure the envoy (Guan Xue agreed in order for the Secret Service to intervene in this mission), and went to the fortress instead of the envoy.

Asano Daigo and Guan Xue agreed to this plan for their own interests.After Song Zhuowen arrived in Dongning, he began to carry out the mission. Although it was difficult and dangerous, the progress was relatively smooth, and he discovered Japan's even greater ulterior secrets hidden in the fortress.​

Liaison officer He Shan provided the time and place where Xia Tao and Lao Qian were going to meet. Guan Xue began to arrange the arrest and reported the operation to Asano Daigo. Asano Daigo took it very seriously and sent the Japanese military police to assist in the blockade and support.

Song Zhuowen wanted to tell Lao Qian the news, but it was too late. Lao Qian had already gone to his residence to meet Xia Tao.

Zhuo Wu, who learned Zhuo Wen's information, knew that Lao Qian was in great danger at this moment, so regardless of the risk that Zhuo Wen might appear at the same time, at the critical moment, Zhuo Wu fired a warning shot and allowed Lao Qian to leave the roundup area safely, but XiaThao died.
