The middle-aged man burst out laughing, "Haha, look at you, beauty, you're so good-looking, how can you have such a bad temper? What's with the violence?"

  He said that and stretched out his hand to Li Yulan's shoulder, Li Yulan looked at him with disgust, turned her head away and ignored him, slapping the man in the face.

  Li Yulan was also a master from outside the region, with a palm power much stronger than that of ordinary people. The man was hit and let out a loud cry of pain, looking back at Li Yulan in disbelief, then angrily shouted, "Hey! You think you can just say no to our toast and get away with it? Do you know who I am?"

  Li Yulan snorted coldly, "Oh, someone as powerless and low-ranking as you, why should I care who you are?"

  "That man shouted, 'How dare you! Come here!'"

  That man shouted loudly, and immediately several thugs rushed over, wanting to seize Li Yulan.

  Li Yulan's eyes turned cold, and with a swift movement, she dodged the first person who pounced on her. She kicked him in the abdomen, then turned around and punched another person, followed by a vicious knee strike to the third person's chin. Next, she chopped down at the fourth person's neck with her palm, and finally, she gave the middle-aged man another resounding slap.

  The middle-aged man let out another miserable cry.

  The underground casino was always extremely chaotic, and over here Li Yulan had gotten into an argument with several middle-aged men, which hadn't drawn too much attention, but still many people turned to look this way.

  Those middle-aged men were lying on the ground, one of them shouted, "You little girl! Do you know who we are? Dare to say what you are? We will find you and teach you a lesson!"

  "Oh, really?" Li Yulan raised an eyebrow and smiled slightly, leaning forward and saying, "Me? My name is Li Yulan, I'm the eldest daughter of the Li family. Who exactly wants to teach me a lesson?"

  Those middle-aged men heard Li Yulan's words, and they widened their eyes in shock. "Wh-what?! You're the young mistress of the Li family! I...I was wrong, Miss Li! We were wrong! Please forgive us!"

  Li Yulan hummed and kicked one of the men with a look of disgust, then turned around and left.

  Li Yulan said that today was originally intended for investigation, but who would have thought that they encountered a few abnormal old men, disrupting their own plans.

  Li Yulan's original plan was to casually play a few rounds of gambling, secretly observing the environment and staff of the underground casino. Now that things have escalated into a fight, she might as well not bother with the gambling and just use brute force to solve the problem.

  Thinking of this, Li Yulan beat the several henchmen and those middle-aged men to the ground, swept away the chips on the table, and walked out the door.

  Several waiters hurriedly tried to stop Li Yulan, "Hey! Miss! Miss! Don't be angry, stay and play for a while..."

  However, they couldn't stop Li Yulan. With a few quick movements, she dodged them and walked out of the underground casino's door.

  Not far from walking out, Li Yulan turned back again, took a sneak peek at the underground casino, tidied up her clothes, brought several pieces of equipment, and quietly walked back.

  Just made a round in the casino, Li Yulan has roughly understood the overall structure of the casino, this time sneaking in from the back door.

  There is a staircase near the back door leading to the second floor of the underground casino.

  Li Yulan climbed up the stairs and reached the second floor where the managers and staff of the underground casino were waiting.

  Li Yulan walked around the second floor, found the manager's office of the underground casino, and quietly and quickly walked to the door of the office. She stuck her ear to the door and listened, but there was no sound inside.

  Li Yulan smiled and produced a delicate silver needle from her hand, manipulated it in the keyhole of the door for two times, opened the lock on the door, and pushed open the door.

  The office was empty except for a pair of furniture decorations placed in great disorder.

  Li Yulan observed for a while and then approached the table inside, carefully searching for evidence related to Luo Hui's case.

  Suddenly, Li Yulan heard footsteps outside, furrowed her brow, stood up, and stuck to the door to take a look.

  The footsteps outside were chaotic, Li Yulan furrowed her brow, wanting to dodge into the room, but she noticed they were rushing towards the office where she was.

  Li Yulan let out a sigh of relief and with one swift motion, she burst out of the office and knocked down the first thug who was running towards her.

  The thugs behind him were stunned for a moment, then they all shouted together, "It's her! It's her! Catch her quickly!"

  Li Yulan kicked one of the thugs with a swift and decisive motion, then clenched her fist and continued to attack, quickly knocking down many people.

  The thugs cried out in pain, and someone shouted, "How can this little girl be so fierce!"

  "She's quite a fighter!"

  "Grab her! Take her away!"

  Although Li Yulan kept knocking down the thugs around her, new ones kept rushing up.

  Li Yulan was tough, but after entangling with these people for a long time, she couldn't help feeling tired and lacking in physical strength.

  At this time, two people suddenly emerged from the crowd of thugs. Li Yulan threw a punch at one of them, but instead of falling to the ground like the other thugs, he stretched out his hand and caught Li Yulan's fist.

  Li Yulan was taken aback, since returning to the country, except for Du Ming, no one had been able to withstand her punch.

  The man caught Li Yulan's fist and kicked out with his leg towards her abdomen. Li Yulan gritted her teeth, shook off the opponent's hand, dodged to the side, and took a step back.

  Another person also stretched out his fist and slammed towards Li Yulan. Li Yulan stretched out her arm to block it, and took another step back.

  Li Yulan and her opponent exchanged two moves before she immediately realized that the other party was not an ordinary fighter, and it was very likely that they were also from outside the country.

  Du Ming had previously told Li Yulan that this casino and Luo Rui might be related, so it's normal to have high-level players from outside the country. Li Yulan gritted her teeth and thought to herself that she was too careless this time.

  Li Yulan and these two people joined hands after that, the rest of the fighters were unable to intervene, silently flashing to one side.

  Three people kept exchanging blows, Li Yulan was originally one against two not difficult, but before that had fought with so many thugs and lost a lot of physical strength, now these people around her were constantly harassing her, interfering with her movements, and eventually fell into a disadvantage.

  Li Yulan became tense, if things continued like this, she would end up losing in the end!
