Du Ming and Jin Ling'er carefully studied the materials of Qi Changrui and others, and finally discussed a countermeasure plan. Du Ming left Jin Ling'er's home.

  Du Ming returned to Yun Cai's home, thinking that if he went undercover, no one would be responsible for Yun Cai's safety during this time. After some thought, he called Li Yu Lan.

  Li Yulan picked up quickly, "Hello, Mr. Du? What's the instruction?"

  Du Ming said, "I have another task here, do you want to accept it?"

  "Of course, but..." She hesitated for a moment before continuing, "I messed up the last mission, will Mr. Du still let me complete tasks on my own in the future?"

  Du Ming smiled and said, "This doesn't matter, I've already said it last time, just let it go, but this time you must take it seriously, this task must be completed."

  Li Yulan said firmly, "Of course, I will definitely try my best to complete the task. What is the task?"

  "Because I have something on during this period of time, so I might be busy for a while. During this time, you need to take my place and protect the safety of Yun Jia's young mistress, Yun Cai."

  "Alright Mr. Du, I guarantee this task will be completed."

  Du Ming felt slightly relieved, but then Li Yulan curiously asked, "Mr. Du, may I ask if you've had anything happen recently?"

  Du Ming thought for a moment and said, "We recently investigated the power organization of Luoye within our borders. Since Luoye is so mysterious outside our borders and we can't find any intelligence clues about it anywhere, we have to start investigating from within our borders. I want to go undercover in one of its subordinate organizations within our borders."

  "Undercover?" Li Yulan exclaimed, "Isn't that very dangerous?"

  Du Ming said, "What? You still don't trust me?"

  "It's also," Li Yulan said with a smile, "after all, it's Mr. Du, what can't be done?"

  Du Ming again reminded Li Yulan a few words and hung up the phone.

  That night, Du Ming went to the underground boxing arena that he almost smashed last time. This time, as soon as he walked to the entrance, the two security guards widened their eyes in horror and shouted, "How did you come back!"

  Du Ming said casually, "Want to play a game of Arena Fist today, huh? What's wrong, won't let me in?"

  The two security guards looked at each other, and one of them said, "Alright, I'll take you to see our manager."

  The security guard led Du Ming down the steps and into the boxing arena just like last time.

  As two people passed by the boxing ring, a regular audience member in the field recognized Du Ming and shouted loudly, "That's No. 12! He's here again!"

  This immediately attracted the attention of the audience, and people looked at Du Ming, and many people cheered after a moment of surprise.

  Du Ming's last match left a deep impression on everyone, as if it were a performance in a movie. Some people even suspected that the boxing arena had arranged it itself. Afterwards, many people came to watch Du Ming's matches, but he never returned again.

  Today, Du Ming finally appeared again. Everyone who had heard of Du Ming's "exploits" cheered and screamed, with someone shouting, "Let him go on stage!"

  This was the first time in a boxing arena that someone passing by under the ring attracted more attention from the audience than the boxers competing on the ring, and even the two contestants and the referee on the ring couldn't help but look down at him.

  Du Ming took a look and was delighted to find that the two people on the boxing ring were actually familiar faces, both of whom he had fought before. One was No. 23 and the other was No. 19, except that today they were wearing different number plates than last time.

  Du Mingchong and the other person smiled, both of them were nervous for a moment, thinking back to Du Ming's performance last time he came, they suddenly became dispirited, couldn't even play this game well, made mistake after mistake, finally just punched each other a few times and that was it.

  The security guard took Du Ming directly to the manager's office, knocked on the door and walked in.

  The office desk in front of the manager's office was broken by Du Ming before, and now a new one has been replaced. The manager is smoking and playing with his mobile phone behind the office desk.

  The security guard rushed to the manager and said, "Manager, that number twelve came again last time. He said he wants to come and fight today."

  The manager finally looked up and saw Du Ming seemingly startled, shouting "Is that you?!"

  Du Ming smiled normally, and the manager shouted towards the outside, "Where's Little Sun? Come over quickly!"

  The staff member who gave Du Ming the number plate last time walked in, and the manager pointed at Du Ming and shouted, "Quick! Arrange for him to go on stage right away for the next match!"

  Xiao Sun responded with a sound and took Du Ming out of the office.

  Du Ming said, "Why is your manager so excited when he sees you?"

  Xiao Sun replied, "You were too sensational last time you were here, and afterwards our customer flow suddenly surged. We all made money thanks to you. The manager dreams of having you come back and hopes you can always compete here."

  Du Ming said, "That's not possible, I'm busy, coming here to play games is occasional relaxation, won't be coming all the time."

  Xiao Sun's face twitched, this was the first time he had heard someone say that coming to a boxing arena to participate in a tournament was to relax, but after seeing Du Ming's strength last time, he felt that what he said seemed quite normal.

  Xiao Sun first took Du Ming into the boxer's rest room and let him rest here for a while, then went to make arrangements and would soon let him go on stage.

  Du Ming nodded in agreement and pushed open the door into the rest room.

  The rest room was the same as last time, with several boxers resting inside. Hearing the sound of the door opening, a few people raised their heads to take a look and found it was Du Ming, then exclaimed, "Is that you?!"

  Everyone looked up and curiously looked over.

  Du Ming took a glance at the inside of the rest room, where many people had been beaten by him last time. He gave everyone a slight smile and found that his seat from last time was still empty, so he walked over and sat down directly.

  The whole rest room suddenly boiled over, with some people amazed, others nervous, some terrified and others annoyed, all shouting at once.

  "Isn't this number twelve?!"

  "Yes, how did he come back?"

  "He won't be playing tonight, will he?"

  "Whoever gets him will be unlucky soon?"

  Some people who were not present last time and did not know Du Ming curiously asked, "What's going on? Who is this person? Why is everyone so excited?"

  Another person explained to him, "This is the twelfth number who knocked down a dozen people at once in our boxing arena! The legendary Twelfth Number!"
