When the two men saw Hu Feng, they called Hu Shao respectfully, then took out the walkie-talkie around their waists and said a few words. Suddenly, the iron door slowly opened from the inside. Seeing this, Leng Xuan couldn't help but feel a little weird. This iron door seems to be able to be opened only from the inside, but cannot be opened from the outside. What is behind this iron gate? Leng Xuan's heart suddenly filled with strong curiosity.

After the iron door was opened, I saw a staircase leading to the underground. Hu Feng led Leng Xuan down the stairs, and then passed a passage more than ten meters long. At the end of the passage, there was also a gate. On both sides of the gate, there are seven or eight people guarding there. After Leng Xuan approached, although he hadn't entered the door yet, he had already heard the clamor from the other side of the door. When the door was pushed open and Leng Xuan entered, he saw a huge underground boxing ring inside. In the center, there is a protective net of iron wire, and around, it is full of seats. At this moment, those seats were filled with spectators, each and everyone shouting excitedly towards the boxing ring. Seeing this, Leng Xuan's heart suddenly understood, it turned out that this is the place to fight black boxing.

   At this moment, Hu Feng said with a smile: "Brother Leng, let's go up, someone has already prepared the private room for us to watch." Leng Xuan nodded and followed Hu Feng up the stairs. Above those ordinary seats, there are more than a dozen luxury private rooms, which are specially reserved for the rich or those with status to watch the game. Immediately after the two entered the private room, someone brought drinks and some fruit, and another brought a small laptop. On the screen of the computer, the information of several people is displayed. Hu Feng explained with a smile: "The information in this computer is about each boxer. We can understand the boxer and make bets based on these materials. Of course, there are also boxers here because they are confidential and will not provide personal information, so only You can gamble by luck."

Leng Xuan asked, "You guys aren't legal, right?" Hu Feng smiled and said, "If it was legal, it wouldn't be built underground. However, although gambling on black boxing is prohibited, my friend's house is a bit of a mess. Identity and status, so even if someone knows about it, they don’t dare to do anything, there are unspoken rules at every level.” Leng Xuan nodded understandingly: “Then you come here often?” Hu Feng replied: “Only occasionally Come and bet two, the stakes here are not small, although my family has some money, but it is not rich enough that I can spend it casually. Brother Leng, how about it, do you want to bet two small?"

Leng Xuan glanced at the still empty boxing ring and asked, "How much is the bet here?" Hu Feng smiled and said, "The minimum bet is two million, and there is no cap." Leng Xuan was a little surprised. The backstage boss who came to this black fist is not only bold, but also very rich. After thinking about it for a while, Leng Xuan turned his eyes to the computer screen, and saw that there were six boxers' information on it, three of them were foreigners, and the other three were natives. Leng Xuan asked, "Are there any rules for fighters participating in boxing competitions?" Hu Feng shook his head and explained: "There are not too many rules, but you can participate if your strength reaches a certain level. And there are no rules for the competition, as long as you can beat your opponents. Knock down is fine, even killing the opponent is fine, every fighter who participates in the competition must sign a life and death certificate before going on the field.”
