At this time, it was already dark early, and when Lin Su and the others left the laboratory, it was already dark outside.

Today, Lin Su and Dean Wen had a few words in his office, and when they came out, it was already completely dark outside.

"Xiao Lin, Professor Wu's house is still some distance from us. You wait here for a while, I'll go and borrow you a bike. After a while, the two of us rode over together. ”

Dean Wen handed his bicycle to Lin Su and asked Lin Su to wait for him not far from the research institute.

Hearing Dean Wen's words, Lin Su nodded obediently.

After Dean Wen left, Lin Su was still there reminiscing about the experiments they did during the day today.

At this moment, Lin Su suddenly heard a voice in the distance, "Help!", and then, there was no sound.

Hearing this voice, Lin Su chuckled in his heart.

After she took a look, she parked Dean Wen's bicycle directly in place.

Then, while walking in the direction of the voice that had just come out, he secretly called out to the system in his heart.

"System, I want to make a wish!"

"Ding, the wishing system is at your service, may I ask ......"

Before the system's words were finished, Belin Su interrupted.

"Help me locate people in danger nearby, and then I need good skills. It's that when I encounter danger, I can protect myself and others. ”

"Positioning requires a primary wish! The host pays a primary wish and can get fifteen minutes of self-defense experience. The host pays an intermediate wish to gain three days of self-defense experience, and the host pays an advanced wish to gain a lifelong self-defense skill. Which one do you want to choose?"

"Locate first!"

"Ding, the host meets the conditions for making a wish, and the host makes a wish successfully. The host will consume a primary wish to locate the person in the vicinity where danger is occurring. At the same time, the system will help the host plan the shortest path. Ask the host to pay attention to the green scissors around them and act according to the green scissors. ”

As soon as the system's voice fell, a green arrow appeared around Lin Su, which was not very obvious, but could be seen by Lin Su.

Lin Su didn't expect the system to be so humane. I also provide a route.

Lin Su didn't delay, and ran over briskly in the direction pointed by the arrow.

As Lin Su got closer and closer to the person who was in danger, Lin Su was transformed by the system to have relatively sensitive ears. At this time, some whimpering cries for help can also be heard intermittently.

After hearing the cry for help, Lin Su sped up his running.

After changing a detour, what appeared in front of Lin Su was a dim alley.

Because at this time, it was completely dark, and there were no lights in the alley. Therefore, even if Lin Su was standing at the mouth of the alley, he couldn't see what it looked like inside the alley.

Moreover, because Lin Su's hearing is more sensitive, he can hear the sound coming out of the alley. If you are an ordinary person, even if you walk through this alley, you will not find that at this time, something is happening in the alley.

Probably hearing Lin Su's footsteps, the sound in the alley suddenly stopped.

Lin Su could faintly hear the voices of struggling business and asking for help, but the other voices could not be heard.

"System, exchange fifteen minutes of self-defense!"

"Ding, the host has made a successful wish, and the host ......"

At this time, Lin Su didn't care about the voice coming from the system in his head at all.

She stood at the mouth of the alley, raised her voice, and said deliberately: "Comrade Sheriff, there is a voice here, and the voice I heard came from here." ”

Lin Su could hear that after his words fell, the struggle of the people in the alley became even stronger.

But soon, the alley was quiet again.

found that no one came out inside, and Lin Su was not ready to wait for him here longer.

She relied on her self-defense skills and walked boldly towards the alley.

As she walked, she consciously accentuated the sound of her footsteps. Let the people in the alley be able to hear clearly.

Lin Su had just walked halfway when he heard a voice coming from inside the alley.

It was the voice of a girl shouting for help, and the sound of a approaching footsteps.

Hearing the sound of footsteps, Lin Su secretly raised his vigilance.

In a few seconds, the person in the alley had already come to Lin Su. From a distance, it was a tall man.

As the distance between him and Lin Su got closer and closer, the man also saw Lin Su's appearance clearly.

After seeing Lin Su's appearance clearly, the man slowly slowed down. Then, there was a malicious look in his eyes.

It's no wonder that this man would be like this, after all, although Lin Su is not short in height. However, she is indeed quite thin. Moreover, she herself looks very delicate. At a glance, she is the kind of squeamish little girl who will not be taken seriously at all.

Seeing that this man had some contempt for the enemy, Lin Su also had some joy in his heart.

When this man pounced on her, Lin Su didn't dodge at all, but directly met her. Then, before the man could react. Directly tripped on his leg, and when the man stumbled, Lin Su directly took control of his hands.

With a coincidence, Lin Su directly pressed the man to the ground.

The man didn't expect Lin Su to look thin and weak, and his skills were so good. Before he could react, he was already under control.

He struggled violently under Lin Su's hands, but he didn't expect Lin Su's slender and delicate hands to tremble at all at this time, controlling him so firmly that he couldn't break free at all.

At this time, Lin Su heard footsteps coming from the alley again.

Lin Su was stunned in her heart, when she came in, she obviously felt that there were two people in the alley. Could it be that this man still has accomplices?

Thinking of this, Lin Su couldn't care about anything else at all. Hit it hard directly on the man's neck.

Because of the help of the system, Lin Su can directly find the position he is looking for. Moreover, she uses a lot of force.

With this knife, the man didn't have time to react at all, and he fell into a coma.

Seeing the man unconscious, Lin Su let go of him and put his eyes on the alley, ready to deal with the person who came out in a while.

However, when she saw the person clearly, she was shocked.
