Seeing Lin Hao not in a hurry to go back, Wang Sisheng and Li Ya didn't ask too much. They just nodded and arranged for someone to escort Yu Yuchen back. Yu Yuchen, who was sitting in the car, was already drowsy. Looking at Yu Yuchen's pretty red face, Lin Hao's lips showed a smile.

"It seems that the development of drugs is really a good thing for Yu."

As night fell, a motorcycle with a fast electric switch drove out from the far end of the road and finally stopped in the parking lot opposite Tianyu group.

Because the gate of Tianyu group is still some distance away from the parking lot, the security guards have not found any trace of the motorcycle. Even if they do, they will not care too much. After all, they have not touched the fundamental interests of Tianyu group, so they will not start.

A slender woman in black tights stepped down from the motorcycle and took off her helmet. The golden mask glowed with cold light in the moonlight. The cold bird looked at the building not far away, and there were still several lighted rooms in the building. She said to herself coldly.

"It seems that the joy of victory has really dazzled the minds of this group of people. It is sad that they do not even have the basic idea of thinking about danger in times of peace."

When lengniao was about to take out and sneak into the Tianyu group's instrument, suddenly his hand was held by others. Lengniao looked up and saw four ruffian young men standing in front of him and surrounded himself.

The head of a man with yellow hair enjoyed the cool feeling from the palm of his hand. His face was full of pride and greedily said, "beauty, is it too unsafe for you to dress like this in the middle of the night? If Cosplay is really true, I think you should choose in the daytime, so as to match your figure from a distance. I believe that many people will come to appreciate your appearance

With that, Huang Mao put out his hand freely and was ready to take off the mask on Leng Niao's face. When he got hold of it immediately, Leng bird suddenly put out his hand and punched Huang Mao's back corner to force him to stop.

Huang Mao was angry at first, but soon began to laugh. Looking at the three people around him, he said, "I like to be friends with such a woman with a temper like this."

With that, Huang Mao continued to stretch out his hand if he did not change his mind. This time, Leng Niao suddenly took back his arm, which was contained by yellow hair, and immediately launched a counterattack. How could Huang Mao, a rogue, be an opponent of cold bird after strict training? The body simply can't bear its strong impulse and falls directly on the ground.

The remaining three people looked at each other, did not think that the seemingly weak woman in front of her should have such power.

With the help of three people, Huang Mao slapped the dust off his body and got angry: "Damn it, it's really a toast. Don't eat or drink. Brothers, give it to me!"

Under the command of Huang Mao, three people coax forward, not realizing that they have been in danger.

The cold bird's merciless attack knocked all three people to the ground, and they began to howl.

Huang Mao was also shocked by the scene. His legs trembled, and his teeth trembled. He begged for mercy: "Auntie, I have no eyes, and I have unintentionally offended you. Please forgive me for being young and unreasonable."

Cold bird did not listen to yellow hair's words, looking at the security guard standing in front of the door not far away, seemed to be planning something.

Seeing that lengniao didn't answer, Huang Mao thought lengniao was angry and refused to forgive himself. He knelt down on the ground and kowtowed: "Auntie, I really know I'm wrong. Please give me another chance. I swear I won't do such a thing again!"

Cold bird mouth showed a smile, it seems to think of a safe sneak into the Tianyu group, then squat down, looking at the yellow hair white face said: "I can let you go, but you have to do something for me."

Listening to the cold bird's reply, Huang Mao said excitedly, "don't say one thing. Even if my aunt asks me to do 100 things, I won't have any hesitation, as long as I can do it."

Lengniao pointed to the gate of Tianyu group and said, "I need you four to attract the attention of the security guard."

Huang Mao suddenly raised his eyebrows and said, "Auntie, that's Yujia's Tianyu group. The whole Binjiang city is well-known. If we look for AIDS and pick things up, we may also be implicated."

The cold bird snorted coldly and took out a stack of money from the motorcycle: "if you can do as I said, these money is your hard work, and I will never let you do things in vain."

Looking at the new cash in cold bird's hand, Huang Mao's four people looked at each other and nodded: "give it to us."

Cold bird handed the money to Huang Mao's hand: "that's settled. You go first and I'll come later. If you let me know what tricks you're playing, don't blame me for being rude."

Huang Mao swallowed hard and took three people to Tianyu group.

Looking at the back of Huang Mao's four men, lengniao presses the button and sees a platform extending from the inside of the motorcycle. Lengniao takes out a backpack from the rear of the motorcycle, puts the instruments on the platform into the bag, ties the cool stick on the motorcycle to the side of his legs, holds a steel crossbow and suspends a grenade at his waist. After confirming that there is nothing missing, he sets out behind Huang Mao and others.Huang Mao and other four people slowly walk to the door. Huang Mao looks back cautiously. Seeing that there is no cold bird, he is relieved. He wanted to retreat quietly. However, he still has a sense of panic in his heart when he thinks that the cold bird can easily knock himself to the ground. He can only bear to go forward.

As soon as the plan was about to be implemented, a man behind Huang Mao said, "brother, you won't really agree with that woman's request, will you? Although that woman seems not simple, we have to face the whole Yu family, which is also very shocking. I hope you can think about it carefully

After listening to the words of the people under his hand, Huang Mao's mind was broken up and he didn't know what to do.

The cold bird was staring at the hesitant four people not far away, and then guessed their thoughts. With a sly smile, he raised the steel crossbow, put it on his shoulder, and directed his pen in the direction of the gate. Because the cold bird didn't want to hurt people, the arrow shot directly on the wall, which quickly attracted the attention of the patrol guards in front of the door.

Seeing that it was a powerful steel crossbow, the security guards instinctively felt that something was wrong, so they called out all the guards stationed in front of the gate, and the yellow hair not far away became their primary suspect.

Seeing that the security guards rushed fiercely, Huang Mao began to run away without even thinking about it. Huang Mao and others' running made the security guards more sure that the crossbow and arrow were related to it, so they began to hunt in all directions. Only two guards were left in front of the door.

Two security guards and their helpless look at each other and smile bitterly. They can only stand in front of the door silently, waiting for the return of their companions.

Seeing that the time was ripe, the cold bird in ambush suddenly launched an attack. Before the two security guards came to their senses, they directly took them down and knocked them unconscious. The cold bird was unhurt and did not cause any disturbance.

Relying on the cover of the night, the cold bird carefully pastes on the wall and moves slowly. As far as he can see, there are two teams of security guards on patrol, which makes Leng bird sigh for the protection measures of Tianyu group.

In order to avoid causing unnecessary disturbance, lengniao took off his backpack, took out the equipment from the motorcycle again, turned on the switch, and began to shoot in front of himself. He saw several figures on the screen, and the colors were different.

After knowing the number of security guards, Leng Niao quickly tackled one group of security guards who came to him first. Another group of security guards who heard the sound also came. Their attention was attracted by the equipment on the ground and the injured colleagues, forgetting the existence of the murderer.

A security guard looked at the instrument and said, "this is a heat detector. Call minister Lin quickly. The people coming are not what we can deal with."

Seeing no response, the security guard turned his head slowly and saw the cold bird standing straight in front of him.

"It seems that you are very good. You know the heat detector, but it's too late. I have a question to ask you. Where is your laboratory?"

The guard's eyes subconsciously turned around and said, "I don't know."

As soon as the voice fell, cold bird punched the security guard's abdomen with a strong blow. The security guard couldn't help covering the pain. He gasped and asked, "who are you in the end? Why do you want to join the Tianyu group?"

Cold bird also does not answer, a knife will be its stun on the ground, pick up the heat detector on the ground.

"If you don't want to tell me, I'll find it myself."

Cold bird continued to move forward, went to the front of the building, and took off the scope of the monitor, hidden in the corner.

Lengniao thought: "Yu Yuchen's ability to develop this kind of drug must not be carried out in a conspicuous place, but must be carried out in a relatively hidden place. But there are only a few rooms with lights on, which can not be them at all. Now that the drug research has just made progress, Yu Yuchen will certainly strike while the iron is hot and increase the progress of drug manufacturing So the lab must still be working. "

Cold bird thought while looking at the towering building, fell into deep thinking, and finally decided to enter the building first to make a decision.

The security guard on duty in the monitoring room saw a figure passing by on the monitoring screen, so he called up his colleagues and cautiously went out with a rubber baton in his hand to look for the characters on the screen.

As soon as they opened the door of the building, they were knocked unconscious by the cold bird. The cold bird dragged the two people in and continued to go deep into it. They began to investigate the direction of the research room.
