After half a lifetime of navigating the world, the system tells me to be a good big brother!

Li Qing ran very fast, and even though slippers weren't suitable for running, his speed didn't slow down much.

Just one floor away on the stairs, Li Qing arrived at Aunt Qian's door in just over ten seconds.

Li Qing was knocking on the security door, and the knocking was quite loud.

After making sure the person inside could hear the knocking, Li Qing stopped.

He pressed his ear against the door, listening intently to see if anyone was speaking inside.

But his knocking went unanswered; all he could hear was the faint groaning of Aunt Qian.

From Aunt Qian's groans, he understood that she had indeed fallen quite hard.

Looking at the security door in front of him, Li Qing really didn't have any good ideas on how to open it.

At that moment, because of the noise he had just made, Aunt Qian's neighbor across the hall opened her door and came out to see what had happened.

"Xiaoqing, what are you banging on Aunt Qian's place for? It's so loud."

Li Qing turned his head and saw that the person who had come was an old neighbor he had lived with for many years.

"Uncle Feng, I just finished eating at home when I heard Aunt Qian upstairs say that something had been broken, so I came up to check on her."

I just knocked on the door, but Aunt Qian didn't answer. I only heard her softly moaning inside.

After hearing his explanation, Grandpa Feng's expression changed, and he understood something as well, becoming somewhat flustered.

While he was explaining to Grandpa Feng, Li Jiantang finally climbed up as well.

Panting heavily, Li Jiantang looked at Li Qing, who was blocked outside the security door, and took two steps forward.

"Get out of the way!"

Li Jiantang pushed Li Qing aside, and then picked out one of the keys from a bunch of keys.

With slightly trembling hands, I struggled to insert the key into the lock, and as the key turned, the security door opened smoothly.

Li Qing looked at the security door that his father had opened, a hint of surprise on his face, but he didn't investigate what was going on and quickly stepped inside.

Upon entering, one sees Aunt Qian lying on her side on the floor in a living room with the same layout as his house, next to broken porcelain shards.

Upon approaching, Li Qing didn't dare to move Qian Da Niang blindly, but instead observed her condition first.

At this moment, Aunt Qian had a furrowed brow, her lips were slightly purple, and she was making a weak sound.

The other person was curled up, one hand tightly clutching their chest, looking extremely uncomfortable.

Li Qing leaned down and put his ear to the other person's mouth, finally managing to understand what was being said through the groans.

"Heart medication, heart medication..."

Li Qing realized that this was a heart attack, and he quickly looked up and scanned the room.

Li Jiantang, who had followed him in, looked at the scene before him, adjusted his breathing, and calmly called out to Grandpa Feng, who was still standing outside the door.

"Old Feng, quickly bring me the nitroglycerin pills you keep at home!"

After hearing Li Jiantang's words, the somewhat dazed Grandpa Feng quickly ran home.

The old man was usually a slow and steady person, walking with a steady pace, but now he was running.

"Old Li, here's some nitroglycerin!"

Li Jiantang took the nitroglycerin pills from Grandpa Feng and handed them to Li Qing.

Without further delay, he gently supported Aunt Qian's head, poured a handful of nitroglycerin pills from the small bottle, pried open her mouth, and fed them to her.

After feeding Aunt Qian the medicine, he gently straightened her body and laid her flat.

He took out his phone and dialed 120 directly.

Only after finishing all this did Li Qing finally breathe a slight sigh of relief.

Meanwhile, Aunt Qian, who was still lying on the ground, showed signs of easing her furrowed brows after taking a nitroglycerin pill.

"Dad, I didn't even think about it, how come you still have a key to Aunt Qian's house!"

Li Qing then looked at his old man and asked him his question with a smile.

Li Jiantang, of course, understood what this brat meant, and rolled his eyes at him. Just as he was about to explain, Huang Hongxiu's voice rang out from outside the door.

"In our building, Aunt Qian has given a key to every old neighbor."

Not only does your dad have one, I have one too!

As Huang Hongxiu spoke, she walked in from outside the door and squatted down in front of Aunt Qian.

"Sister Qian? Sister Qian? Can you hear me? If you can, just say 'hey'."

"Why……"

The voice was very weak, but it still answered Huang Hongxiu.

Huang Hongxiu breathed a sigh of relief and kept talking to Aunt Qian. As time went by, more and more neighbors who heard the commotion gathered outside the door.

After the neighbors gathered, Li Qing understood why Aunt Qian was using the key.

The building where Li Qing's parents now live, as mentioned before, belongs to the staff quarters of a textile factory.

The residents in the stairwell were all old neighbors and colleagues who had lived together for more than 20 years.

But as these people get older and their children no longer live with them, they begin to feel a sense of crisis.

So it wasn't just Aunt Qian's key that was delivered to every household in the building; almost every household in the entire building could open the doors of other households.

It could be said that these elderly men and women have unwittingly formed a mutual aid alliance for senior citizens.

Whenever one family is in trouble, the others will always lend a hand.

They had no choice but to do this because their own children weren't around.

The ambulance arrived quickly, in just over ten minutes.

When the medical staff arrived, Li Qing also stepped outside. After they helped carry Aunt Qian onto the stretcher, he went forward to help take her downstairs.

It was thanks to Li Qing's good physique that it was possible to carry him down the stairs in this not-so-spacious corridor.

Watching the ambulance disappear into the distance with its siren and flashing red and blue lights, Li Qing felt a mix of emotions.

As the ambulance drove away, another system notification appeared before his eyes.

[The upstairs neighbor has been rescued by the host and is out of danger. Mission complete. Merit points +200]

Looking at the merit points that had been credited to his account, he now had 651 merit points, which meant he could participate in another lottery draw.

However, the current situation did not meet the conditions for the lottery, so he stopped thinking about it and returned home with his parents.

I sat down on the sofa at home again and rolled up my own hair into a hand roll.

Smoke billowed from his mouth, drifting upwards and obscuring his vision.

His eyes kept darting between his parents. He hadn't felt much before, but what happened today made him realize that his parents' hair had turned a lot whiter.

It turned out that his parents had grown old without him even realizing it.

He also thought of the apartment building where his parents now lived, which had no elevator, no property management, and even the hallway lights were not working.

The only good thing is that my parents have old friends here.

Li Qing had already made up his mind; he could no longer let his parents stay there.

He should find a way to find a more convenient place to live, both for his parents and for himself.

Although he doesn't have enough money right now, he knows that with the system around, none of this will be a problem.
