The stairwell was very cold, relying on the warm current from the white jade ring, Han Wei could insist, it was strange to say, constantly touching the white jade ring, in addition to the warm current, even the original sleepiness disappeared.

I waited for an hour or so, and the hard work paid off, and there was a sound of footsteps downstairs, the sound was not very loud, and the sound should be on the lower two floors. Li Hua had already instructed the security guards that there was no need to patrol the stairwell at night, and the sound that appeared at this time could naturally eliminate them.

The footsteps are getting louder and louder, knock, knock, knock, in the quiet space, it seems so crisp, as if the rhythm of a heartbeat. Han Wei and Li Hua both held their breath, for fear of making a noise and alarming each other.

Suddenly, the footsteps faded away, and it was supposed that the other party had stopped walking. Was it discovered? Han Wei looked at Li Hua, the other party was much more experienced, and he was the backbone of the present. However, you can only see the black face, and you can't judge it from the look.

After waiting for about a few dozen seconds, the footsteps sounded again, judging from the sound, it continued to come up. Li Hua suddenly pulled up Han Wei, quickly flashed into the corridor on the fifth floor, hid behind the staircase door, and then closed the door. The footsteps were getting closer and closer, and soon I could feel that I had reached my side, but through a door, no one could see each other. Who is coming? Is it Lin Xue, or the mysterious doctor, or someone else?

The person who came did not stop, and continued to walk up, Han Wei and Li Hua both counted silently in their hearts, every footstep was a step, and after about a minute, the person who came should have gone up to the next level. Li Hua and Han Wei walked out at this time, but they still didn't turn on the lights, and slowly followed with the guardrail. Probably followed the second floor or so, and there was a sound of footsteps downstairs, still the kind that was very careful, and occasionally the sound of a few steps was heavy before Li Hua heard it. The people who came after him also went up, who would this person be? Compared with the previous person, this person deliberately hidden, and it was obviously much more suspicious.

This person has already reached the top floor, and when he goes out, he is on the rooftop, and if he goes back, he is likely to be discovered by someone who comes later. After hesitating for a moment, Li Hua simply pushed open the door and went to the rooftop, Han Wei naturally followed, both of them were ready to attack, but strangely, the rooftop was empty. Although the moonlight outside is not very bright, you can still clearly see people more than ten meters away, and now they are gone, which is really strange.

Han Wei and Li Hua hurriedly stepped forward and looked around carefully, there were few places where they could hide, and they quickly searched for each other, but they still didn't find each other. Could it be that the footsteps just now were just an illusion? However, Han Wei and Li Hua both heard it clearly, if it was an illusion, they were both sure that it would be impossible. Or, the footsteps are the mysterious black shadow, there is no body at all, as if invisible, how can they find each other. If this is the case, perhaps, the mysterious black shadow is standing in front of them at this time, thinking of this, Han Wei and Li Hua immediately become nervous.

At this moment, there was a sound of footsteps behind the door of the rooftop, and the other party seemed to not want to hide when they reached the roof. Han Wei and Li Hua immediately hid next to the equipment room, where there was a corner, as long as the other party didn't come, they could barely hide.

The footsteps quickly stopped, and the two of them breathed a sigh of relief, and were about to go out to see who it was. Suddenly, a voice sounded: "Come out." ”

It was the later people who spoke, has it been discovered? Han Wei looked at Li Hua with a puzzled expression, how did the other party find out, could it be that there was some kind of special induction, just by the residue of the breath in the air, he could know if there was anyone there?

Li Hua gestured to Han Wei and motioned for him to go out slowly, Li Hua clenched his baton, took a deep breath, and prepared to go out. Before the person moved, there was another sound of footsteps, and from the direction of the sound, it can be known that it was not made by a later person, because the sound came from the side of the parapet. You must know that the parapet wall is already the most edge of the rooftop, and there is no hiding place at all, is the other party flying in the air? It is now certain that he was the one who started with him, which may explain why his existence could not be discovered. Li Hua naturally wouldn't go out at this time, clinging to the wall, and didn't even dare to come out.

"Where's the stuff?"

"You throw it over."

The voice was from the same person, the voice of a middle-aged man, and the location where it came from should be the person who came later. After speaking, I heard a soft "bang", which should be the impact of something. Immediately after a while, the middle-aged man did not speak, and after waiting for a few seconds, there was a slight sound of paper rubbing.

"What's wrong with the numbers?" The middle-aged man's voice sounded again, but no one answered, and it felt like a person was talking to himself.

Li Hua had already walked to the very edge of the wall, slowly probed out, and saw a middle-aged man in a fur coat, holding an envelope with a certain thickness and a piece of red on it, which should be money. Opposite the middle-aged man was a man in a white coat, could it be the mysterious doctor?

The middle-aged man slowly approached the doctor, because he couldn't see the doctor's face, and he didn't know what the other party's reaction was, he was a little excited to see the action, and as the middle-aged man got closer and closer, the doctor finally began to step back. Soon retreated to the position of the parapet wall, and there was no way to retreat.

Suddenly, the middle-aged man still held the envelope in his hand on the ground, his expression became hideous, like a hungry wolf, and pounced on the doctor, first punching the doctor in the stomach, just a punch, immediately knocked the doctor to the ground, bent like a shrimp. Immediately afterwards, the middle-aged man tightly pinched the doctor's neck and pressed the doctor's body with his legs, making it difficult to struggle. The doctor whined so little that he couldn't even scream, and it didn't take long for him to be strangled to death.

Who the hell is the doctor, is it the person you see in the surveillance? Who is the middle-aged man, and why did he kill the doctor?

There are too many doubts, and the parties need to solve the mystery, Li Hua and Han Wei hurriedly rushed out, and did not hide their voices at this time, and were found by the middle-aged man before they ran out, looking at them with a look of doubt and horror. Li Hua was a step faster, and in the blink of an eye, he was in front of the middle-aged man, and the baton smashed down. Li Hua was not sure of the identity of the other party, and did not attack the dangerous part, but only hit the back.

By the time the middle-aged man reacted from his shock, it was too late, and as soon as he wanted to get up, the baton hit his left shoulder. It is not a key part of the body, Li Hua's strength is not small, at least eight points of strength, but the middle-aged man is in pain, but he didn't shout, which shows that he is not an ordinary person. The middle-aged man came back to his senses, his speed was not slow, a fish rolled, and then he turned over, without any hesitation or dodging, and kicked Li Hua violently, directly attacking Li Hua's lower body.

Li Hua dodged to the side, and after a certain distance, the opponent's attack power was reduced a lot, and then he raised his right leg to block, and the moment he collided, he only heard a "bang", but it was extremely loud on the quiet rooftop. The two retreated at the same time, and Li Hua shook his right leg to relieve the pain. It's just an instantaneous confrontation, and he has a certain understanding of the middle-aged man, he is agile, and he is definitely professionally trained, looking at the attack action, there is a certain difference between it and the army, but it is like a police officer and an armed policeman.

It has been a long time since he met a powerful person, Li Hua not only did not worry, but instead had a strong desire to fight and chose to take the initiative. As soon as he approached the other party, the middle-aged man had already stepped back, in the direction of the door. Obviously, the other party had no intention of fighting, and looked at the doctor not far away from time to time, his expression changed, and he should be hesitating to leave immediately. How could Li Hua let him leave, immediately threw the baton in his hand over, and while the other party was dodging, he stepped forward in a few steps and blocked the front of the door, wanting to leave, he could only defeat him.

Seeing that the retreat was sealed, the middle-aged man went directly towards Han Wei, and casually took out a knife from his pocket. Li Hua only thought about blocking the other party's way, forgetting that there were still Han Wei and the doctor, and hurriedly stepped forward at this time, but he was already a step too slow.

When Han Wei was confronting Li Hua and the middle-aged man, he helped the doctor aside, the doctor was very thin and didn't need to work too hard. The doctor's face had turned purple, and if he was a step too late, he might have lost his breath. At a close distance, Han Wei could already see the other party's face clearly, it was the person he saw in the surveillance. At this time, seeing the middle-aged man coming, he hurriedly got up and held a baton, protecting the doctor behind him, whether he can figure out the truth of the matter, the doctor is the key, and he must not be allowed to die.

The middle-aged man's knife stabbed over, Han Wei did not panic, stared at the opponent's knife, and when he was about to reach his side, he retreated, and then slammed down the baton. The knife cut through the clothes on Han Wei's abdomen, and the thick coat couldn't resist the knife, and a blood mark appeared on the abdomen, but fortunately, it was not very deep. Before the middle-aged man could issue the second blow, the baton had already smashed on the knife, and he immediately shot the knife down. Han Wei's move is very dangerous, but the effect is very good, the other party has lost his weapon, and he can't kill him with his fists and kicks alone, and he can completely drag it until Li Hua's arrival.

The middle-aged man naturally knew this, and instead of chasing Han Wei, he went to pick up the knife, and the doctor was on the side, and he could kill him if he picked up the knife. After all, he was still a step slower, and as soon as the middle-aged man's hand touched the handle of the knife, a gust of wind hit his ears, and he subconsciously dodged to the side. Li Hua's foot flew past the middle-aged man's ear, and although he didn't kick it, the other party couldn't get the knife. Li Hua kicked the knife away, and it just landed at Han Wei's feet, where would Han Wei be polite, picked up the knife, and then surrounded the middle-aged man with Li Hua. Behind him was the daughter wall, with Han Wei on the left and Li Hua on the right, and the middle-aged man knew that it would be difficult to escape, so he simply put on an attack posture.

Now it's not a one-on-one fight, Han Wei unceremoniously smashed the baton at the middle-aged man, there was not much room to dodge, and when he barely dodged, Li Hua's attack had arrived, and he couldn't dodge it, he was kicked in the thigh, and his body lost his balance for a short time, and then leaned forward. Li Hua's attack came again, and the elbow of his right hand came to the top of Mount Tai, and the middle-aged man's reaction was not unpleasant, and his body lost his balance and was stunned sideways, which could be dodged.

Taking advantage of his illness to kill him, Han Wei saw the opportunity to fly and kick it, but at this time there was no way to avoid it, the middle-aged man was kicked in the chest, hit his daughter's wall hard, and immediately vomited blood. Without any respite, Li Hua kicked his right calf, and there was a sound of broken bones, and he was afraid that it would be difficult to stand up.
