Gao Letian's words made Deng Yunmao suddenly enlightened. Now that he has a goal, his anxiety has been reduced a lot.

Having a goal is not enough, his strength must be improved, and the system is his backing. Now he must study this system carefully.

"Hey, system..." Deng Yun called in a low voice.

As before, there is no response from the outside world. It seems that the system is not voice-controlled.

Try another way. Deng Yun closed his eyes, relaxed his body, focused on the word system, and soon got the feeling.

When he opened his eyes, he saw the projection of the system interface right in front of him.

The floating interface was so eye-catching, Deng Yun felt a chill in his heart, his secret was exposed so quickly.

I looked around carefully and found that no one was paying attention.

Fortunately, fortunately, only I can see it.

Deng Yun felt relieved and began to examine the system interface.

The current experience value is 16, click on the details, and the reason why the experience value is obtained will be displayed above.

"What does touching the edge mean?" Deng Yun frowned, full of doubts in his heart.

Is it the edge of death? Then the experience points given are too little.

The character level column shows Marksmanship Apprentice. Click on it and find that the next level is a question mark, and how to get promoted is also a question mark.

What does this... mean? No conditions, random upgrade?

Fortunately, there is a progress bar on it, which shows that you can click it when you reach 100 experience points, but it is only 16 experience points, which is far from enough.

Look at the attribute column again. Points have been added to the damage column and aiming accuracy column. The other columns have zero attributes. There are rules next to them. Experience points can be exchanged for attribute points.

It seems that being able to blow up zombie heads before was related to this damage attribute.

There are other interfaces, all showing question marks, which makes Deng Yun seriously suspect that the system manufacturer is being lazy.

16 experience points are too little. Deng Yun is reluctant to point attribute points and plans to save more experience points. When he reaches 100 points, he will try the upgrade progress bar.

Based on game experience, Deng Yun feels that the benefits of upgrading are far greater than the benefits of attribute points, but the question arises, how to gain experience?

Going out to kill zombies? No, no, there is no chance of death, and he is also afraid.

Picking up the slingshot, Deng Yun was about to cry. He had clearly chosen the gunner profession, but he actually used the slingshot as a weapon. It was so embarrassing.

You can't be idle all the time, you still need to practice. Deng Yun looked around and found a few empty bottles in the corner.

He walked over, picked up the empty bottles, put them in the corner, then stepped back, picked up the slingshot and took aim.

This move immediately attracted everyone's attention, and Gao Letian watched with interest.

Every time he aimed, Deng Yun had a strange feeling that he could accurately hit any position on the bottle.

When he takes a few steps back, that feeling disappears immediately.

Is there a distance limit? Is it an aiming accuracy attribute?

Deng Yun moved forward, and the feeling appeared again.

I visually measured the distance and estimated it to be about ten meters.

With good marbles, Deng Yunla shot them all out.

With a "bang" sound, the bottle exploded, and the glass ball smashed into the wall, stirring up a layer of white ash.

Everyone was dumbfounded, and Deng Yun was also shocked by this power.

Gao Letian narrowed his eyes and murmured: "It seems that I have to re-evaluate his combat effectiveness."

The wall was damaged, and Deng Yun quickly put away his slingshot and quietly returned to where he was sitting.

It seems that ordinary training is meaningless. He has auto-aim and critical hit, so there is no need for additional training at all.

Maybe you can ask Gao Letian to see if there is any way he can help you gain experience.

The monitoring room is an independent room. One wall is filled with many monitors, and the images captured by the monitors are constantly switched on it.

When Gao Letian saw Deng Yun coming in, he looked puzzled: "What's the matter?"

"I want to fight zombies in actual combat." Deng Yun felt guilty.

Gao Letian nodded and said: "It's very simple, just go ahead."

Deng Yun was confused. It's so simple, but you didn't even tell me the solution to the problem.

"Just... just... go directly?"

Gao Letian smiled, called up a surveillance screen, pointed at it and said: "Look here, the electric car area, a row of electric cars. If you use a slingshot to trigger their alarms, zombies will be attracted to you. You can aim at will."

Shoot, the nearest electric car is more than twenty meters away from us. If zombies rush over, we have time to close the door."

This plan is good, and Deng Yun agreed repeatedly.

The two came to the lobby, and Gao Letian shared his thoughts with everyone.

Hearing that Deng Yun wanted to practice slingshot, Zhang Yong was the first to agree and expressed his willingness to help.

Wang Dabiao stared and objected repeatedly at the top of his voice: "There are zombies in the underground garage too! Can this door be opened?! If zombies rush in, isn't it all over?!"

Qian Wang beside him also echoed: "Mr. Wang is right, safety comes first."

"It just so happens that this time I can confirm how many zombies there are in the underground garage and reduce their number. I think it's pretty good." Gao Letian explained.

After hearing his explanation and witnessing the power of Deng Yun's slingshot just now, maintenance worker Master Zhang stepped forward and was willing to help.

After some preparations were completed, Master Zhang and Zhang Yong controlled the opening and closing of the left and right doors. Gao Letian was on guard in the monitoring room and used the intercom to contact him if he found any dangerous situations.

Deng Yun filled his pants pocket with marbles and stood nervously in the middle of the double doors.

After the monitoring room confirmed that the door was safe, the door slowly opened, revealing a gap for a person to enter and exit.

The underground garage has been in disrepair for a long time, and the lighting system has been broken a lot. The garage is completely black and white, which affects the vision. Fortunately, the lighting in the control room is normal and I can see the surrounding things clearly.

At this time, a faint fragrance came from behind, and Yan Shifang came up behind her, stood on tiptoe and looked outside, looking for that familiar figure.

Having rejected the other party before, Deng Yun was embarrassed to say hello.

The electric car area was more than 20 meters away from the gate. Deng Yun tried to draw his bow and aim, but he didn't get that inexplicable feeling.

It’s not a big problem, there are so many electric cars, even if you are blind, you can still hit one.

He let go of his hand, and the marble drew a parabola and hit the cement floor of the garage without hitting.

Seeing Zhang Yong's doubtful eyes, Deng Yun smiled awkwardly: "My hands are slippery, my hands are slippery."

The marbles still had enough energy to bounce on the ground, hit the wall, and then bounced to other places. Continuous crashing sounds were heard in the garage, and under the light in the distance, figures shivered and gradually moved closer to the door.

I didn’t expect that it would be okay if I hit the target accidentally.

The first zombie appeared in the field of vision. Its ugly face infected by the virus was like a demon emerging from its cage. It grinned with a drooling mouth and roared towards it.

The strong visual impact made Deng Yun's heart beat faster. He quickly took out his marbles and aimed them. The zombies rushed within ten meters, and a strange feeling surged through his body.

Release and launch, the zombie will fall to the ground with a headshot.

The system issues a prompt, experience value 2.

"Beautiful!" Zhang Yong clenched his fists and looked excited.

Four or five zombies rushed out of the shadows, and Deng Yun felt guilty. There were so many at once, and he didn't know if he could deal with them.

Two zombies were shot in the head by marbles, and the remaining three rushed within Wumi. Deng Yun could smell the putrid smell on each other's bodies, and his legs couldn't stop shaking. It was too late, and his hand speed couldn't keep up!

At the critical moment, the two gatekeepers quickly closed the door.

With a "bang" sound, the door made a banging sound.

The zombies outside kept knocking on the door, and the continuous banging sound made people feel uneasy.

Wang Dabiao cursed loudly and his face turned red.

At this time, the sound of an alarm sounded in the distance, and the zombies outside the gate were attracted, and the sound of banging on the door subsided.

Deng Yun's legs became weak and he collapsed on the ground, gasping for air.

"Are you okay, brother?" Zhang Yong's face was full of concern.

Deng Yun waved his hand and said with a wry smile: "It's okay, I'm just nervous and scared."

"You will get used to it after a few more visits." Zhang Yong patted Deng Yun on the shoulder.

Wait until Deng Yun calms down and start the second round.

Just like last time, when the situation is urgent, just close the door and use the alarm to lure the zombies away.

At the end of this round, Deng Yun felt that his ability to withstand pressure had increased and he was not as unbearable as the first time. At least he could still stand.

After more than ten rounds, my arms were sore and my fingers were stiff.

There were corpses lying on the ground outside, and there were not many marbles left in the pockets.

The two people guarding the door next to them were stunned. In their impression, Deng Yun seemed to have never missed a marble, and a zombie.

Deng Yun had to end today's monster-fighting upgrade. Looking at his slightly trembling right hand, he shook his head helplessly. His physical fitness was too poor. Even with plug-ins, he couldn't fight for a long time.
