System, hurry up! Hand it over to the supermarket and hug the country's thigh

There was no movement.

If there was nothing wrong with Lu Xi's ears and she was not hallucinating, then those popping sounds should have been real, and the place where the sounds came from seemed to be not far from her.

She held her breath nervously for a moment and looked around.

However, the balcony illuminated by the incandescent light was still empty except for herself.

This made Lu Xi feel puzzled. If some messy thing came in, the system would definitely be the first to know about it, which means that the sound did not come from here.

She shifted her gaze towards the dark barrier, and after thinking about it for a moment, she felt creepy and her heart was pounding.

The sound did not sound like something falling to the ground or hitting the wall, but rather more like... Lu Xi subconsciously clenched her fists and looked at the void of color.

A trace of doubt flashed through her mind. That sound was more like the sound made by Long Ruilin when he punched the indestructible black protective shield last time!

"Bang!" The sound came again.

Lu Xi's heart suddenly tightened when she was frightened by the sudden sound. She was very sure that something was constantly hitting the black protective shield.

But this time the force was not very strong, it was a bit like he was testing it cautiously.

Recalling the previous introduction of the system, Lu Xi had a bold guess in his mind.

The system once said that every time a transaction with another dimension began, the entire supermarket was pulled into an independent space.

It can only communicate with the outside world through a specific space-time gate, so it can be said to be very independent.

So, could it be that outside this black protective cover, there is another time and space, and the one who made the sound just now was an unknown creature wandering in other time and space.

This unknown creature accidentally saw their dark protective shield and became curious, so it wanted to break through the shield and get in.

This sudden guess made Lu Xi's heart beat faster, and she felt a little nervous.

Curiosity was like an invisible hand, driving her to find out more and uncover the mysterious veil.

However, Lu Xi also knew very well that curiosity killed the cat, especially for a weak and powerless "newbie cat" like herself.

She was staying here alone, and if something unexpected happened, the consequences would be disastrous.

Therefore, she needs some reliable help to ensure her safety.

So, Lu Xi picked up the phone without hesitation and began to call her friends: "Longlonglonglong, come to the second floor quickly, there is something on the balcony of my sister's room that needs your help!"

Then, she continued, "Xiao Cang, you and Long Long should come over here too, hurry up!"

For the sake of her own life, Lu Xi thought it would be better to call the two of them over together.

After all, one more person means more strength and more security, and she cherishes her life very much now.

Just two or three seconds after Lu Xi hung up the phone, Long Ruilin and Cang Wuya appeared in front of her like two gusts of wind.

Their faces were filled with deep worry and their eyes were fixed on her. After making sure that she was okay, they both breathed a sigh of relief at the same time, and their tense expressions relaxed a lot.

Cang Wuya walked quickly to Lu Xi's side and spoke first, with a hint of urgency and concern in his voice: "Master."

Although it seems nothing has happened in the current environment, but they were called over here in such a hurry, there must be something going on.

After entering the room, Long Ruilin immediately used his spiritual sense to carefully check the surrounding environment, but did not notice anything unusual.

But he did not let down his guard. After all, his sister was not very cautious, but if there was no special situation, she would not be so anxious to call both of them up.

So he followed Cang Wuya's footsteps and asked with concern: "Sister, what happened?"

Unexpectedly, as soon as Long Ruilin finished speaking, the collision sound rang out again at an inopportune time.

"Bang!" The sound suddenly rang out in the silent room, seeming particularly abrupt, breaking the original tranquility and attracting the attention of the two people who had just arrived.

Lu Xi was just worried that the guy outside would give up after she called people over, but now she felt that the voice came at a perfect time, saving her the trouble of explaining to the two people herself.

"Well, I called you two up here just for this sound. I've never heard such a sound before, this is the first time I've heard it.

Moreover, since everything outside is unknown, I don’t know what is constantly hitting the black barrier outside.”

She frowned slightly, looking at the dark color outside the balcony, and seemed a little worried. "So, in order to prevent any unknown danger from happening, I called you two up together."

Long Ruilin nodded, understanding that his sister was a little scared.

He turned his head, glanced at the black barrier, quickly located the position where he was hit, and with a flash of his body, he stopped there steadily.

After touching it with my hands, I still didn't feel any Yiyang.

Long Ruilin stayed in the air for a while, listened carefully to the sounds of several collisions, and made his own judgment.

"The sound of the collision is getting stronger little by little. The thing outside should be relatively small, but it is very powerful. It is quite powerful when it hits it with its body."

At least I used four levels of strength in my last punch, which resulted in the sound I made now.

Lu Xi breathed a sigh of relief when she heard that it was a small creature. At the same time, there was a hint of surprise and admiration in her eyes as she looked at Long Ruilin.

She couldn't help but exclaimed: "Wow, Longlong is amazing. He can analyze so much information just from the sound."

Lu Xi really admired Long Ruilin. He at this moment was different from the soft and cuddly Long Long who always called her sister behind her.

But cute just the same.

So, according to Long Ruilin's analysis, the impact sound seems like some creature trying to break through the black protective cover and enter this unknown place.

However, one thing is undeniable, even if it is small in size, when the creature is unknown, the danger is also unknown.

However, Lu Xi feels at ease now that someone is with her.
