The Great Wall of Badaling, the historical crystallization of the ancient people of country Z, this dragon crawling on Badaling, at the beacon tower at the highest point of Badaling at 888 meters, there is a secret door switch, the secret door leads directly to the underground tunnel, and the end of the tunnel is a crypt blocked by a steel door.

This crypt is the general base of the dragon group entrenched in the capital, this secret base is the top secret of the country, only the core members of the dragon group know, and the secret door needs fingerprint identification to open, even if ordinary people inadvertently touch the secret door, they can't open the secret door.

There is a layer of steel doors behind the secret door that missiles can't open, this steel door is called 'Dragon Gate', if you want to pass the 'Dragon Gate', you must identify the retina of the members of the Dragon Group, after the identification is successful, the camera outside the steel door will scan your whole body, as long as a link does not match the information, the Dragon Gate will turn into a sharp spike door, and there will be countless muzzles on the walls of the surrounding tunnels, strafing the people who try to sneak into the Dragon Group base, until the target is confirmed to be dead.

At this moment, the Badaling Great Wall is in the tourist season, and the dense travelers are like swarming ants, and at the highest point of the Badaling Great Wall, two black shadows flashed, quickly burrowed into the beacon tower, and disappeared between the crowds.

At the bottom of Badaling, the underground base of the Dragon Group, there is an archive room in the deepest part, where a large number of confidential documents of country Z are stored, including the confidential documents of the 'strongest blade' YN experiment plan a year ago, and this archive room cannot even be entered by the core members of the Dragon Group, and must be a team leader and above with the authorization of the senior level before entering the information.

At this moment, a middle-aged man with gray hair was hurriedly flipping through the materials in the archives, he looked a little anxious, turning the cabinets into a mess, and the two large long tables in the archives were also covered with all kinds of messy materials, but the middle-aged man still didn't seem to have found what he was looking for.

This person's name is Tang Xiong, the number two person of the Tang family in the capital, the deputy director of the First Bureau of the Ministry of State Security, and now he is in charge of the dragon group, when Zheng Changfeng was still the leader of the dragon group, he was Zheng Changfeng's top boss, everything the dragon group did must be authorized by him, and now the leader of the dragon group has been replaced by Zheng Shuang, although everything has to be approved by him as before, but the actions of all the core members of the dragon group are under his control, including the team leader Zheng Shuang.

"Why didn't you mention the information of the "Strongest Blade" experimental base? Tang Xiong slapped the long table in front of him fiercely, he finally got the permission to enter this confidential archive, but he couldn't find what he wanted, how could he be willing?

The day of trading with that adult is approaching, but the sword demon has not contacted him for a long time, thinking that the plan has failed, and the rest of the mess can only be cleaned up by himself, although he is not worried that the sword demon will betray him, but the sword demon failed to complete the task, and the transaction with the adult cannot be carried out, so he had to enter the archives and personally look for confidential information about the 'strongest blade', but unfortunately he found nothing after looking for a morning.

Although there is some sensitive information about the YN project in this archive, what the adult really wants is the 'strongest blade' and the exact location of the laboratory, what should I do now? Tang Xiong's thoughts were racing.

At this moment, a figure was displayed on the display screen on the wall of the archive room, which was his most powerful henchman, the former deputy captain of the Dark Dragon Team of the Dragon Group, Xiao Feng, and now after Zheng Shuang took over as the leader of the Dragon Group, this Xiao Feng also successfully sat in the position of the Dark Dragon Captain, but he was still Tang Xiong's pawn in ambush in the Dragon Group, monitoring the every move of other Dragon Group members for Tang Xiong all the time.

"Director, it's not good." Xiao Feng's voice was very hurried.

"What's going on?" Tang Xiong asked unhurriedly, didn't he say don't let people disturb him?

"It's the team leader, she's back."

"What's so strange, let her wait for me in my office, I'll be over in a moment." Tang Xiong's face was full of unhappiness, so he made a fuss about it.

"No, it's not just the team leader, he also brought one person back." Xiao Feng's voice outside the door became strange, because he saw Zheng Shuang walking towards him, and Zheng Shuang was followed by a person, wasn't this person Ye Chen?

"Who?" Tang Xiong couldn't help frowning, although the leader of the dragon group had this authority, he couldn't just take people back to the base casually, after all, this was a confidential base directly under the Ministry of State Security.

"Ye Yechen." Xiao Feng's voice became trembling.

"What!" Tang Xiong's face changed, could it be that the Sword Demon betrayed him?

Listening to a bang, the iron door of the archive room seemed to have been hit by something terrible, and it collapsed with a bang, and the smoke and dust drifted everywhere, and the iron door was deeply imprinted with a humanoid mold, and the person in the mold was Xiao Feng, who had just stood at the door, and at this moment he had fallen into a coma.

The smoke and dust gradually dissipated, and two figures walked in from outside the door, one was graceful, and the other was slightly thin but extraordinary, weren't these two people Zheng Shuang and Ye Chen?

"Zheng Shuang, don't you want to do it, the leader of the dragon group? This is a confidential archive, how can outsiders be allowed to enter casually? Tang Xiong scolded angrily, although he said so, he had already guessed in his heart, but he couldn't have imagined that the Sword Demon would betray him.

"Tang Xiong, you used my trust in you to spy on Ye Chen's whereabouts, but I still regarded you as an upright person, but I didn't expect you to be so dirty." Zheng Shuang shouted angrily.

"Zheng Shuang, I don't know what you're talking about, do you want to commit the next crime? Do you know what happens to the following offenses in this dragon group? Tang Xiong threatened, even if he knew that the matter was exposed, as long as Zheng Shuang and the others had no evidence, he could still shirk all this cleanly.

"Wife, don't talk nonsense with him, just kill this kind of scum." Ye Chen said helplessly on the side, he slowly stepped forward, stepping over the unconscious Xiao Feng, his eyes red.

"Ye Chen, you wait, I'll convince him to die." Zheng Shuang took out his mobile phone and turned on the playback function of the mobile phone, only to see that the mobile phone was a somewhat noisy recording, but the speaker's voice could still be heard clearly.

This person's voice is the Sword Demon, and this paragraph is what the Sword Demon said after being hypnotized by Ye Chen before he died, in order to prevent Tang Xiong from denying it, Zheng Shuang specially recorded it, if Tang Xiong wanted to deny it, this was the best evidence.

"Haha, Zheng Shuang, what can you do if you get the evidence? You're not qualified enough to arrest me. Seeing that the matter was completely exposed, Tang Xiong no longer hid it, and finally tore his face, but before he finished speaking, he was slapped away by Ye Chen, and his fat body hit several rows of bookcases where confidential documents were placed in a row, lying on the fallen bookcases in the third row, with blood stains hanging from the corners of his mouth, and most of his teeth were lost, it seemed that Ye Chen's injuries were not light.

"Ye Chen, I know that you are powerful, and I also know that you are a black list killer, but you dare to come to the Dragon Group Base today, it is the biggest mistake you have made in your life, haha." Tang Xiong laughed again.

Ye Chen really couldn't help but want to go up and slap him again, but Ye Chen quickly realized a few murderous auras not far behind him, and the secret path was not good, so he hurriedly turned around and rushed towards Zheng Shuang, but unfortunately Ye Chen's reaction speed was still a little slower.

I saw two sharp darts-like things with four corners penetrating Ye Chen's body protection gas shield, one of which cut Ye Chen's cheek, but there was no poison on this dart, and Zheng Shuang was also successfully rescued by Ye Chen, Ye Chen helped Zheng Shuang up, and the secret way was still careless, I thought it would be okay to clean up those dragon group members outside, but I didn't expect that there was such a powerful master hidden in this base, who could break through the domineering shield, which showed that the other party was not a fuel-efficient lamp.

Two figures appeared in front of Tang Xiong and in front of Ye Chen, silent, like air, no wonder even Ye Chen didn't notice their existence, the outfits of these two figures are very similar, both are masked, headband forehead guards, half-length shirts, hand armor, palms tied with bandages, red brown pants, typical Japanese ninja attire.

"Ye Chen, there is a way in heaven, you don't go to hell, there is no door, you come to vote, although this sentence is old-fashioned, but it is best to describe your current situation, haha." Tang Xiong stood up from the ground, his eyes cold.

"It's a little devil again." Ye Chen pulled Zheng Shuang up to protect him, and his expression became tense, because the strength of these two Japanese ninjas was very strong, if there was only one person, Ye Chen's domineering sixty percent was enough to deal with it, but if the two joined forces, under that extremely high tacit understanding, the strength would more than double.
