The office building was pitch black, almost reaching the point where you couldn't see your fingers, only the street lamps left a little invisible light through the windows, but fortunately, Du Yufan's strength was amazing, and after a little adaptation, he found the stairs and went straight to the sixth floor of the topmost place.

This building is just an empty shell, there is nothing but the walls, during the period of being Qinglongzi, Du Yufan has carried out countless tasks, experienced many such situations, and with extremely rich experience, he quickly found a hurried room, which was chaotic, just enough to hide people.

"Yitong, you hide here first, try not to make a sound."

Du Yufan found a secret place, put Yang Yitong down, and spoke softly.

"Well, I'll wait for you to come back."

Yang Yitong didn't say anything, although she was scared to death, she didn't show it, she kissed Du Yufan on the mouth, and then quietly retreated to the hiding place, she believed that Du Yufan could come back to save her.

Under the office building, everyone in the Blood Wolf Mercenary Group already felt that the leader was giving orders: "Leave four detachments to surround the entire building, and the other six detachments will go in and search, each detachment will search one floor, if you find their whereabouts, you must not entangle, you must report it as soon as possible." ”

"Yes, boss."

All the mercenaries received the order in unison, and when the four detachments left behind were scattered and hidden, the remaining six detachments rushed into the building and began to conduct a carpet search, although the building was extremely dark and could not see anything, but they had night vision devices, and darkness was not a problem at all.

The Blood Wolf Mercenary Group is outnumbered, although it has suffered a lot of losses in the woods, but there are still one hundred and ten people, ten people form a small team, when Du Yufan left Yang Yitong's hiding place, the ten-person team that searched the sixth floor had arrived, and was carefully searching, not letting go of any place.

Du Yufan approached these mercenaries silently, his eyes flashed with cold light, gloomy and cruel, he dared to assassinate him, he had to have the consciousness of death, at this moment, without the burden of Yang Yitong, he didn't have to be as timid as before, he could completely kill him.

"Pedal Pedal Pedal T

The building was dark and silent, and the mercenaries' boots made a screeching sound on the floor, which was extremely unfavorable for searching, and they took off their shoes and searched barefoot, because the building was empty, and they could see it at a glance when they entered the room.

Therefore, the mercenaries' search speed was very fast, and in less than five minutes, they were already close to the warehouse where Yang Yitong was hiding.

In the darkness, Du Yufan was like a ghost, silent, hunched over to approach a mercenary, appeared behind him like a ghost, a cold light flashed in his eyes, and suddenly stretched out his hands, holding his chin with one hand, holding the back of his head with the other, and twisting it hard.

"Click!"

The sound of bone cracking came out, and the mercenary didn't even scream, staring at him, Du Yufan gently put him to the ground, and then hid in the corner.

Although the sound of bone cracking was not loud, in this silent environment, there was still a slight sound, and the other mercenary moved his ears, slowly turned around, clenched the submachine gun in his hand, and walked towards Du Yufan step by step, cautiously.

When he walked to the corner where Du Yufan was hiding, a dagger shot out like lightning, not giving him the slightest chance to react, and pierced deep into his heart, at the same time, Du Yufan flashed out, stretched out his palm, and held the mercenary's mouth tightly, not letting him scream.

Du Yufan held the dagger in his hand, turned it hard, and directly smashed the mercenary's heart, and at the same time, covering his mouth to prevent him from making the slightest sound, the mercenary's eyes widened, and he didn't expect death to come so quickly.

Easily eliminating the two mercenaries, Du Yufan continued to sneak, silently like a ghost, slowly approaching the two mercenaries in front of him.

Du Yufan pounced like a civet cat, and suddenly appeared behind a person, his palm suddenly poked out, covering his mouth tightly, and at the same time, the other hand held the dagger tightly, and slashed through the mercenary's throat, the major artery was immediately cut, and blood gushed out like a tide.

After solving him, Du Yufan put it on the ground, this person opened his mouth, but he couldn't make any sound, and the vitality dissipated, and the vitality quickly dissipated.

The other mercenary turned his head, his expression was suddenly stunned, he couldn't see the figure of his companion, suddenly, raised his submachine gun, scanned his eyes around, opened his mouth to call, and suddenly, Du Yufan pounced like lightning and appeared in front of the mercenary like a devil.

A black shadow appeared coldly in front of him, even if the mercenary's psychological quality was extremely strong, he couldn't help but want to exclaim, however, the speed at which he opened his mouth was not as fast as Du Yufan's attack, and before the sound was made, the sword light shot out.

The sharp dagger was like a bolt of lightning, shooting at the mercenary's jaw, directly piercing his jaw, passing through his mouth, and piercing his head, blood splattered, vitality dissipated, and his strength dissipated invisibly, staring at a pair of big eyes and dying miserably.

In just a few moments, Du Yufan easily dealt with the four mercenaries, and then, using the same method, the dagger was like a death scythe, and the lives of the three were harvested again.

However, this time there was some small accidents, although Du Yufan killed the mercenaries, but they made some noise, although it was extremely slight, but in this silent floor, it was still a little obvious, and it was heard by the other three mercenaries.

The three mercenaries were back to back, looking slightly nervous, and slowly walked towards the place where the voice sounded, put their fingers on the trigger of the submachine gun, and would shoot without hesitation if there was a situation.

Suddenly, they saw the corpses of their companions at the sound of the voice, their expressions changed, and they were slightly stunned, it was at this moment of lightning that Du Yufan pounced out, his body twisted, and his iron legs swept fiercely, hitting the back of one of them in the neck.

"Click!"

With a penetrating sound of bone cracking, the mercenary's neck was directly broken, his head leaned forward, his nose was almost close to his chest, and he couldn't die anymore.

At the same time, the dagger slashed through the throat of another person, the force was so fierce that the throat was broken, blood gushed wildly, and the entire head was almost cut off, and he fell to the ground with his hands around his neck.

There was still the last person left, it was the captain of this team, who reacted a little faster and immediately took out the walkie-talkie to report the situation, but he was still a beat slower, and before he could speak, the two companions had already died miserably, and he, almost at the same moment, followed in the footsteps of his companions.

After ensuring the safety of the sixth floor, Du Yufan came to the fifth floor and showed his fangs again......
