Xu Sa only reacted for two seconds, and then rushed in the direction of the roof.

The roof of the city bureau is usually locked by a large lock, and no one usually goes up at all.

When Xu Sa climbed to the top of the building, the door that was usually locked was wide open, and he saw He Xingchen standing in front of the railing from a distance.

He Xingchen stood on the edge of the rooftop, as long as he took one more step forward, the whole person would fall directly.

He stared straight ahead, with no focus in front of him, and a smile on the corner of his mouth, as if he had seen something that made him happy.

"He Xingchen!" Xu Sa calmed down and shouted, but He Xingchen did not react.

Xu Sa was not surprised, on the way back, he had already thought about Wang Hao's problems. Then, He Xingchen and Wang Hao disappeared together, and finally he reappeared on the rooftop.

He Xingchen's idea of being drugged by Wang Hao, he can be even more sure.

Now that Su Tong is not here, Wen Yan is downstairs again, even if he calls someone up now, he won't have time to do it.

And what happened to Wang Hao who was hypnotized by Su Tong before, in case He Xingchen was given heavier drugs, it would be troublesome.

Thinking like this, Xu Sa didn't hesitate and returned to the corridor just now.

There was a fire window in the hallway, and he remembered that there was a section of water pipe in that window, which was used to extinguish the fire by people who fled to the roof of the building in case of a life.

Xu Sa wrapped his coat around his arm, smashed open the fire window, and withdrew the water pipe from inside.

The water pipes are about 10 meters long and somewhat heavy. Xu Sa didn't care so much, he wrapped the fire hose around his body indiscriminately, tied the other end to the protective fence on the rooftop, and then rushed directly towards He Xingchen......

In the serious crime team, Wen Yan stood at the window, frowning and looking at the crowd at the gathering place below.

"Officer Wen, how's the situation going?" Chen Hui locked Shen Ming in the interrogation room, and after putting all the locks on inside and out, he hurried over and stretched out his head to look up.

However, the air-conditioned platform upstairs blocked all his vision.

"It should be fine." Wen Yan looked at the people below who were still nervous just now, all of them showed a relieved expression, and guessed the answer.

"Really?" Chen Hui was still a little uneasy, and stretched out his head vigorously.

Wen Yan was just about to nod when he heard movement at the door.

A group of people carried He Xingchen in, and Xu Sa followed behind, his coat casually on his shoulders, mixed with glass slag in the middle.

"Boss!" Chen Hui's spirit was shocked, and he immediately responded, but when he saw He Xingchen, who was placed unconscious on the sofa, he frowned again, "He Xingchen, what's wrong?" ”

"Scopolamine has been drugged." Xu Sa turned his arm, pulled the muscle he had just strained, and gasped in pain.

He really didn't expect that kid looked quite thin, but in fact he was so heavy, he almost had his hand torn off just now.

"What! That Wang Hao was really bold, and he dared to do something to the police. Chen Hui became anxious when he heard this, "Boss, how do you get this medicine?" Also, that Wang Hao doesn't know where he ran to, should we apply for a wanted warrant? ”

Chen Hui usually doesn't see any easy-going personality, but when he really encounters something that touches his scales, his temper is even more explosive than Xu Sa.

"Calm down first!" Xu Sa pulled a chair aside and sat down, "I called an ambulance and also called Zheng Lao, Zheng Lao said that as long as the dose is not large, it will not be life-threatening for the time being, and at most there will be some sequelae." As for Wang Hao, I've already asked someone to call up the surveillance, but I can roughly guess where he fled to. ”

If Wang Hao didn't mess up and make a move on He Xingchen, they might have to go around in circles this time.

But as soon as he did these things, he had a good guess about Wang Hao's actions.

On the other side, Su Tong was collecting useful evidence in the living room, and Zhou Li was still in the bedroom.

At the open door, another footstep came slowly, from far and near.

Su Tong's movements did not pause at all, and he said without looking back, "Li Hua, the living room and bedroom are almost the same, I remember that Xu Sa mentioned before that Shen Ming had a dark room, which he specially used to wash photos." Look and see if you can find the darkroom. ”

The person behind her didn't answer her, Su Tong paused slightly, and the hand holding the photo stretched out towards an ornament on the table without moving, ready to be used for self-defense.

At the moment when her fingers touched the ornament, a strong wind hit behind her, Su Tong bent down slightly, and quickly dodged to the side.

The face of the person behind her appeared in her field of vision, Wang Hao was dressed in black, with a peaked cap on his head, and a small transparent bottle in his hand hanging by his side, unable to see what was inside.

"Is that you?" Su Tong got up slowly, "You really ran out." ”

Wang Hao tugged at the corners of his mouth, "You idiots, I killed so many people and revealed so many clues to you, and you didn't even know my existence." ”

"So you can't hold back, pretend to be drugged, and then run to the rooftop to get our attention?" Su Tong looked at him indifferently, ignoring a shadow that flashed quickly at the gate.

Zhou Li heard the movement, came out of the bedroom, scolded as soon as she saw Wang Hao, and then pulled out her gun, "Wang Hao, put down the things in your hands, and then raise your hands to your head, do you hear it!" ”

Wang Hao didn't seem to hear Zhou Li's voice, and only continued to say to Su Tong, "That's right, look at how incompetent you are, I have been unscrupulous in this city for so many years and killed so many people. You don't know until now, and you don't dare to expose my affairs. But it doesn't matter, I've already done it for you, and soon, the news about me will be a sensation in the whole city of B. ”

"Wang Hao, ...... you" Zhou Li frowned, seeing that Wang Hao had no weapons on his body, she wanted to rush over and arrest the person directly.

Just before she could move, Wang Hao's words stopped her, "If you dare to take another step, that good colleague of yours who plays with computers will lose his life!" ”

Zhou Li's face changed, "He Xingchen! ”

"What did you do to He Xingchen?" Su Tong took a deep breath and glanced at the bottle in Wang Hao's hand, "You drugged him." ”

Wang Hao's attention was diverted by Su Tong again, "It's still Officer Su who is smart." By the way, the hypnotic prowess you showed on the rooftop that day really impressed me, it's so condescending for a smart person like you to stay in the police station, haven't you thought about doing something else? ”
