Lu Yuan continued to stay in the hospital to protect Dong Haishan, and the Concession Patrol Office also sent additional manpower in the hospital, and in the next few days, Lu Yuan completely acted as a bystander, and No. 76 never found a chance to assassinate Dong Haishan again. Three days passed quickly, Dong Haishan's cargo finally arrived in Hong Kong, thanks to the close relationship with the Ministry of Industry and Bureau of the Concession, Dong Haishan, who left the hospital and rushed to the dock, was surrounded by a large number of concession patrols, and Lu Yuan also fell far behind them.

What Lu Yuan was worried about did not happen on the wharf, although there were many plainclothes spies on the wharf, but the concession patrols around Dong Haishan were very tightly guarded, and those plainclothes spies never had a chance to make a move. According to the plan designed by the underground party, after Dong Haishan received the goods at the wharf, he would quickly board the ship under the cover of the concession patrol, and then take an American merchant ship straight to Chongqing, and the goods would also be handed over to an American company to be transported to Chongqing.

Lu Yuan looked down at his watch, according to the plan, Dong Haishan should have boarded the ship, and seeing the concession patrol escorting Dong Haishan and waiting for the car to leave, Lu Yuan's face immediately showed a cruel smile. In the past few days in the hospital, Lu Yuan's injuries have almost healed, and after being depressed for these days, Lu Yuan has been thinking about dealing with the special high class, and now that he has nothing to do, it is time to implement the plan. Following the two plainclothes agents out of the dock, Lu Yuan, who pretended to be a passerby, looked leisurely, but his eyes never left the two plainclothes agents in front of him.

The two plainclothes agents who left the dock did not notice that anyone was watching behind them, and walked to a black car. The window of the sedan slowly rolled down, and Lu Yuan could see clearly that there was a middle-aged man with a cold face sitting in the back seat of the car. The two plainclothes agents standing next to the car nodded and talked to each other for a few words, then left the car and walked all the way east along the street. Lu Yuan didn't keep an eye on the two plainclothes spies this time, but focused on the black car, and in just a quarter of an hour, three waves of plainclothes spies walked to the sedan and made contact with the people inside.

Could it be a big fish? Lu Yuan's mind couldn't help but churn, looking at the appearance of those plainclothes spies, the person in the sedan was definitely not ordinary. Just when Lu Yuan was secretly pondering, the black sedan suddenly started to leave, Lu Yuan couldn't help but be in a hurry, even if the speed of the car in the city was not fast, it could be kept up with on foot. Just when Lu Yuan was in a hurry, a young man rode a bicycle to meet him, and Lu Yuan reached out and grabbed the front handle of the bicycle.

"Brother, I'm in a bit of a hurry to borrow your bike, and the money is enough for you to buy a new bike." Not surprisingly, the young man who was stopped by Lu Yuan immediately glared, but in the next second, the young man's expression softened. Lu Yuan stuffed a stack of banknotes to the young man, and before the other party could react, Lu Yuan had already changed his bicycle and chased after the black car in the direction where the black car had left.

The speed of the car was not very fast, Lu Yuan only crossed a street corner, and then caught up with the black sedan, and after checking the license plate, Lu Yuan followed far behind. The driver didn't notice that anyone was watching, just driving at the usual speed, Lu Yuan followed the car around the concession for a while, and finally waited for the black car to stop on the side of the street. "Huiyuan Commercial Bank!" Seeing the middle-aged man in the sedan enter a commercial house on the side of the street, Lu Yuan, who was also parked on the side of the street, immediately opened his full-view map.

Sure enough, just as Lu Yuan expected, in the display of the full-view map, there were at least 6 small red dots scattered in this Huiyuan trading house. It's just that there is one thing that is very strange, the middle-aged man who was locked by Lu Yuan showed half red and half blue on the full-view map. What's going on? Lu Yuan was also a little dumbfounded, this was the first time he had seen this situation in a full-view map, red represented hostility, blue represented alliances, but this item was half red and half blue.

After thinking about it for a while, a thought suddenly popped up in Lu Yuan's heart, could it be that this thing is a double agent? Lu Yuan never doubted that his full-view map would be wrong, but the other party's strange situation was really difficult to explain, and if he thought backwards, he could only explain this situation with a double agent. Cao Changhe, who goes by the pseudonym Song Chen, didn't know that he was being targeted, he lurked in the Shanghai Concession under a pseudonym, ostensibly to help the South Korean government-in-exile raise funds and seek intelligence, but in private, no one knew that Cao Changhe had actually been linked to the Japanese intelligence agencies.

Japan has occupied and controlled the Korean Peninsula for a long time, and at a time when some radical organizations and groups are actively resisting Japanese rule, there are many people like Cho Chang-hyuk on the Korean Peninsula who are secretly in contact with the Japanese army. In their view, no matter who is in power and controls the Korean Peninsula, as long as they can live a good life, the Japanese army is so powerful, and it can only be wishful thinking to defeat the Japanese army with a government-in-exile thousands of miles away from their homeland.

But Cho Chang-hyuk is still a North Korean in his bones, and he can hand over some information about the government-in-exile to the Japanese, but he doesn't want to be stained with the blood of any North Korean. After arriving in Shanghai, as the Japanese intelligence agencies were attacked by Lu Yuan one after another, Cao Changhe began to realize that the Japanese were not invincible. In this case, Cao Changhe began to pass on the information of the Japanese army to his connector, in a sense, Cao Changhe at this time was already a real double agent.

Passing on the information that both sides needed to their own advantage, Cho Chang-hyuk did not see anything wrong with doing so, and he was even less aware that danger was looming over him. Guessing that Cao Changhe was a double agent, Lu Yuan did not take action immediately, but launched a tracking of Cao Changhe. For three days in a row, Lu Yuan tracked Cao Changhe, and it was not until he was 100% sure that the other party was secretly in contact with the Japanese military intelligence agency, and then he began to equip Cao Changhe to eliminate Cao Changhe.

Huiyuan Trading House is just a tool used by Cao Changhyuk to hide his true identity, including those ordinary employees in the trading house, who don't know that their boss is actually a North Korean, and they don't know that there are Japanese spies among them. After some preparations, Lu Yuan asked Xu Huanshan to borrow a subordinate, and learned that Lu Yuan had lost the elimination of a double agent, Xu Huanshan couldn't help but become interested, and Lu Yuan had no choice but to temporarily decide to take Xu Huanshan.

Because of Lu Yuan's successive attacks on the special high school, the number of plainclothes agents in the concession has been greatly reduced, and the patrol officers in the concession who secretly collude with the Japanese military intelligence agencies on weekdays are also much more honest, Xu Huanshan said with a smile that all this is Lu Yuan's credit. Lu Yuan and the three of them drove straight to Huiyuan Commercial Bank, and when the car stopped on the side of the street, Lu Yuan immediately opened the full-view map and confirmed that Cao Changhe was in the commercial bank at the moment, and Lu Yuan said to Xu Huanshan and the others.

"There may be a shooting in a while, you better stay in the car and wait for me to come back, after all, this is a concession, and it will not end well when the matter is big." Lu Yuan wanted to persuade Xu Huanshan to stay and wait for him to come out, but Xu Huanshan said that he didn't agree, he still hoped to get information related to the Japanese army from the double agent Lu Yuan said. Seeing Xu Huanshan's resolute attitude, Lu Yuan couldn't continue to persevere, anyway, he also felt that there would be no danger in this operation.

Lu Yuan and Xu Huanshan got out of the car, each carrying a briefcase across the street, and walked into Huiyuan Commercial Bank. When the clerk in the firm saw two people in suits and leather shoes walking in, one of them immediately stepped forward to inquire about the intention, and learned that Lu Yuan and the two were here to talk to the boss about business, so they immediately took Lu Yuan and the two upstairs and went straight to Cao Changhe's manager's office. The staff of the firm mistakenly thought that Lu Yuan and his boss were familiar with each other, but Cao Changhe had no impression of Lu Yuan and the two, and it was only after learning that Lu Yuan and the two came to talk to him about business, Cao Changhe dispelled the doubts in his heart.

The clerk who led the way left immediately, and only Lu Yuan was left in Cao Changhe's office, not giving Cao Changhe time and opportunity to react at all, and the moment the departing staff closed the door, Lu Yuan took out a pistol from his briefcase and put it on Cao Changhe's head. "Don't panic, don't think you'll get out easily, we just want to ask you a few questions, if you want to live, we hope you can answer truthfully." Lu Yuan looked at Cao Changhe with a shocked face expressionlessly, and Xu Huanshan also got up and walked to the door to listen to the movement.

Cao Changhe was really frightened by Lu Yuan and the others, he didn't expect that these two guys with a full face would suddenly change their faces, especially the feeling of being held to the head by the muzzle of the gun is not very comfortable. "Who the hell are you? Why is there a connection with the Japanese military intelligence agency? Why did the special high class send someone to lurk in your trading house? The three questions asked by Lu Yuan in a row made Cao Changhe sweat like rain in an instant, because until now, Lu Yuan and the two have not revealed their respective identities.

Xu is seeing the doubts and struggles in Cao Changhe's heart, Lu Yuan smiled coldly at the other party, "Don't think about anything else, your only way out now is to answer my question just now." If you are not honest, I don't mind shooting you, I believe that the Japanese will not care if you live or die, after all, there are many people like you who grovel in the face of the Japanese. Lu Yuan's words made Cao Changhe, who was already terrified, feel a chill in his back even more, but he still felt that the other party did not dare to shoot, after all, this is a concession.

"Ha, don't you think I dare shoot you here? Do you think the gunfire will attract the patrol of the concession, and then we will not be able to escape? Lu Yuan immediately looked at the other party with a smile, and then took out an iron pipe from his briefcase and slowly screwed it on the barrel of the pistol. It's called *, and it doesn't completely eliminate the gunshots, but I guarantee that even if you stand in the hallway outside through this door, you can't tell if it's gunshots in this room. ”
