This is just an episode.

  However, what Yang Qun and others did indeed eliminated countless troubles for Li Na, which made Li Na look at Yang's eyes full of gratitude.

  Soon, everyone passed through the two buildings and gradually circled under the buildings.

  Many steps have been abandoned or occupied by monsters.

  Li Na and others have many methods. They even directly open up the space between the rooms of the building, not only are there "rat holes" between the rooms." The ground of many rooms has also been cut open, turning into narrow holes that Li Na and others can pass through.

  Li Na jumped from the entrance of the cave again, and everyone finally gradually detoured from the twelfth floor to the bottom of the building.

  On the other side...Li Chao walked down the aisle "handsomely" and assumed a very handsome pose. According to his own words, he would go downstairs anyway. It is better to let him kill directly from upstairs and kill the monsters in the corridor, which will be much more convenient in the future!

  All of this is regarded as Li Chao's special hobby by Li Na.

  "Thanks...thank you..."

   "No thanks, I should." Li Chao walked over heroically. It seems to be saying: "Come and worship me, come and worship me."

  Yang Qun shook his head and observed the surrounding environment.

  This is an elevator room.

elevator?

  Can the elevator still work? The city should have run out of electricity a long time ago. Are they going to take the elevator down?

"This building has its own power generation system, and we found a backup generator underground. We modified the line and the generator is enough to supply the elevator power. At the same time, some of our underground daily electricity consumption can also be satisfied." Li Na saw Yang Qun's doubts and explained.

  Li Na pressed the button to get off the elevator. Although the lights on the elevator were not on, the door opened naturally. Sure enough, as Li Na said, there is a backup power generation system here.

  Entering the elevator, Li Na first pressed the button to close the elevator door, and then pressed the emergency call device.

   "It's us, I'm Li Na, let us go down." Li Na said to the emergency fairy tale device in the elevator.

   "Received, let you down right away." A woman's voice came out from the elevator's dialogue device.

  This emergency call device before the end of the world was originally supposed to lead to 110 or an elevator company. When the elevator fails and people are trapped in it, you can use this device to contact outsiders and ask them to send someone to help themselves.

  But after Li Na and the others modified, the dialogue line of the emergency call device was pulled into the base camp underground and became a simple dialogue device, because the elevator directly leads to their "base camp" so all this must be cautious.

  Looking at their transformation, Yang Qun couldn't help nodding.

  Monsters don’t know how to take the elevator, so they cannot go down the elevator.

  Without an elevator with lights on, no one would have thought that it still had electricity, and would definitely not come in rashly to try.

  In addition to the confirmation of the voice in the elevator, it truly ensures that the underground "base camp" is foolproof, and there will never be outsiders arriving here.

  In the last days, survivors have their own abilities, and safety is the most important thing. They are so cautious that Yang Qun is also understandable. But Yang Qun was also amazed by their simple transformation.

  These transformations are not difficult, just cut off the power line of the elevator and connect it to the generator. The telephone line is even simpler, just connect it directly to the intercom device. It is such a simple transformation, and finally transformed into such a complete safety equipment, human wisdom really cannot be underestimated.

  The elevator is slowly sliding down.

  Below is an underground parking lot, and under the parking lot is an air-raid shelter.

  Ordinary people may not understand it, but according to China’s laws and regulations, every community and every large building must build its own air-raid shelter. Although in order to save money...there are few developers who have built according to law, but under many large buildings, there are still these buildings that are difficult for people to notice on a daily basis.

  The "base camp" is in these air-raid shelters.

  The elevator moves very slowly, perhaps because of insufficient power, or other reasons.

  Yang Qun felt a little strange.

  Li Na...

  Li Na's mood is a bit wrong.

  Some nervousness, some fear, and some...guilt.

  What is going on, Yang Qun can understand if he is nervous, after all, he is bringing a powerful human to his base. And what is the matter with fear and guilt.

  There is a problem here...

  Yang Qun looked calm, but his heart became more cautious.

  "If there is an accident in a while, watch me wink and act." Yang Qun's voice was inaudible, only Ye Shang and Li Chao beside him could hear it. Li Chao looked back at Yang Qun in surprise. He was still preparing to show off his power in front of Li Na. It seemed that what was wrong now? ?

  The elevator is still moving, but there is a sweet smell in the vent and air conditioner.

  The smell makes people's heads a bit heavy.

  The eyes of the soldiers next to Li Na even became blurred. But Li Na's eyes remained sober all the time.

  Poison.

  Psychotoxin, a strong anesthetic.

   makes humans lose consciousness quickly and enter deep sleep.

  Sure enough...

  Sure enough, there is a problem.

  There is fraud! !

  Li Chao and Ye Shang also immediately felt the existence of the problem.

  The nails on Yeshang’s fingers were slowly deforming, and wolf claws gradually appeared. As long as he gently waved, there would be no living people in this elevator except Li Chao and Yang Qun.

  "Wait a minute, you two don't care, take a nap and leave it to me." Yang Qun's voice came. The wolf claws in Ye Shang's hand slowly retracted.

  Yeshang seems to believe in Yang Qun, not to mention Li Chao. They breathed the sweet and greasy breath in the air, and did not make any resistance to these toxins, allowing them to attack their own spirits.

   "It's been a long time since I slept well, I need to sleep for a while." Ye Shang looked at Yang Qun and said openly.

  This sentence was meant for Li Na and Yang Qun.

   Originally, this toxin was far from enough to make Ye Shang faint, but Yang Qun was there. According to his instructions, he gave up resistance and got a good night’s sleep. Leave everything to Yang Qun, and wait until I wake up. Anyway, when I encounter real danger, my body functions will instantly recover.

  The heavy cry came gradually.

  Faced with "Lazy" Ye Shang, Yang Qun couldn't help but shook his head.

This guy is really lazy. He said that he took a nap, just pretending to be unconscious, and the guy Ye Shang actually fell asleep directly on the ground, not caring about the dangerous environment around... It looks like everything is left to you.

  Yang Qun glanced at Ye Shang, then looked back at Li Chao.

  Li Chao was a bit wronged. He was just about to show off his power and wanted to use his power to show off among these survivors, but he didn't expect to be tricked by Li Na. This feeling of helping Li Na kill a large number of monsters and being conspired by him really makes Li Chao upset. This is a feeling of betrayal...

   "Sleep!" Yang Qun's voice came from Li Chao's ear again...

   "Are you going to sleep by yourself or let me do it?" Yang Qun's delicate voice came again.

  There is no way...Li Chao finally gave up resisting, a blurry color appeared in his eyes, and he fell softly.

  At this time, Yang Qun seemed to have discovered something the same. He shook his head pretentiously.

   "There is... toxic!!!"

   "You, actually... plot against us!!"

  Yang Qun pointed to Li Na and said, but his body seemed very weak. He just knelt down when he was about to make a move, and lay in the elevator with Li Chao and Ye Shang.

  Li Na patted her chest in shock. She knew how powerful the opposition was. She was also afraid that the dose of these anesthetics would not be enough to make them dizzy. Killed himself in a rage.

   But I didn’t expect that these powerful fighters would eventually be recruited...

  Hey...the people in the city have never seen the sinister heart outside.

  Li Na shook her head and thought.

  ……

  ……
