Just as Li Yiyi disappeared on the spot, the huge ring in front of the cave entrance also spread out an extremely bright light that people couldn't look at directly around almost at the same time.

The white light rushed towards the ground at an extremely fast speed, but like Li Yiyi's experience, it was also blocked by the invisible wall.

The white light illuminates the surroundings into an almost substantial white within the isolation of the transparent wall, but fortunately, the white light does not last long before gradually decreasing in brightness, and the surrounding objects reappear in view.

After the white aurora subsided, a white wall of light formed in the ring, and just five minutes after the white wall of light was formed, inside the huge underground cave entrance, it was like ten thousand beasts coming out of the cage, and countless roars similar to large beasts gathered towards the cave entrance with rumbling tremors.

In the small spirit realm, Li Yiyi covered his chest with a frightened look, although she didn't feel anything before entering the small spirit realm, but she didn't see much science fiction movies, caves, ring instruments, Nima, I don't know what is wrong with that cave.

It's just that she doesn't know if the ring is trying to release the contents of the cave or to prevent them from coming out of the cave, but either way, she will probably suffer with it.

"What should I do, I won't be trapped here until I die, Nima is still more than 3,000 years old, and he must have gone crazy before he died!"

I don't know if the transparent wall outside has disappeared, if it disappears, even if the ground is already full of demons and monsters, she has a chance to escape from the ground.

But if the transparent wall didn't disappear, then she could also try to take the black ball off the instrument, the instrument was activated after the black ball flew to the groove, and it was clearly a key-like existence, and the transparent wall was formed when the instrument was opened, if so......

Li Yiyi glanced at the sky that had not changed for ten thousand years in the Little Spirit Realm, and his adrenaline began to soar.

"......"

"Roar!!

"Laha ......"

"Ah!!h

"Laha ......"

"Baa !!"

"It's ...... What's going on? ”

At this time, Li Yiyi had already come out of the small spirit realm for ten minutes, and she had already taken out all the treasures at the bottom of the box and was ready to fight hard.

But when she came out, she saw countless black shadow monsters that looked like entities rushing out of the cave, but as soon as those monsters rushed out, they were sucked by the ring with a layer of white light, and then they burned the black shadow monsters like electric mosquitoes, and there was no scum left.

"It's a weak ......"

I didn't expect these black shadow monsters to look quite ferocious, but in fact, their combat power is so weak, and it doesn't feel as if they are not as powerful as the black octopus.

Well, it looks like she should be safe now.

Li Yiyi looked up one by one, and then her body slowly flew towards the sky, this time she flew carefully, so she was not bounced back by the transparent wall, her hands were attached to the transparent wall, it felt like she was sticking to a layer of glass, and this layer of wall did not have any energy fluctuations.

Li Yiyi tried to push a little harder, but the transparent wall did not move at all, three points of force, still like this, seven points of force, not moving like a mountain.

"Frost Wind Thunder Sword"

Li Yiyi had an extra silver long sword in his hand, and then gently pierced it with the tip of the sword, and the touch felt like it was pierced on a layer of tempered glass.

"No, come at that."

The lava shark spat out a small magma ball in the direction that Li Yiyi pointed to, and saw that after the magma ball touched the transparent wall, it became like mercury, and it fell to the ground slippery, and then burned the ground into a deep hole.

"Tsk, Mohua Lake."

Because the place is not large, Li Yiyi made the Mohua Lake the size of a bowl, but this did not affect the power of the Mohua Lake.

"Go."

Just when the black water of Mohua Lake shot a black water arrow in the direction of Li Yiyi's finger, the black ball on the huge ultra-modern technology instrument suddenly shook, and then a circular display screen on the instrument lit up, and at the moment when the display screen just lit up, the black water arrow passed through the transparent wall with a "whoosh" like Zhao Zilong entering a no-man's land.

"Huh?! Passed through. ”

The corners of Li Yiyi's mouth pulled up a strange arc, and then looked back at the black ball, which seemed to be aware of this person's intentions, so when Li Yiyi's whole body was covered with black thunder liquid and was about to rush over, he hurriedly closed the transparent wall.

Li, who successfully penetrated the wall, did not look back again, but directly turned into a silver wind, and came to the very beginning of the office area in the blink of an eye.

In the underground cave, the black ball embedded in the huge instrument actually showed a burst of white garbled on the sphere after Li Yiyi escaped, and then the gibberish became a simple face, eyes, mouth, and gone.

The black ball eyes that showed an expression turned to the place where Li Yiyi left, and after looking at it for a while, his eyes turned into crooked smiling eyes, and the mouth of a bar also bent into a U-shape.

A day later

Li Yiyi returned to Nanping City, in fact, she also wanted to run farther, after all, with her character, she really didn't want to come into contact with something that was not sure if it was a product of the earth.

However, she was still a little curious about the underground cave in her heart, and when she thought about the research institute, she never believed that that kind of buildings and those machines that were extremely out of step with the times could be built by the Great Celestial Empire before the end of the world.

"That'...... Could it be that I don't know when, a starship crashed to the earth, and also smashed into the deep underground, and then such a big thing was discovered by the relevant departments, and then the researchers of the Celestial Empire entered the interior of the spacecraft and began to study the outer space civilization, and then they were at the bottom of the spaceship, and found the mysterious underground cave and the huge metal ring at the entrance of the cave.

After that, they began to study around the cave and the ring, but then for some unknown reason, the research team had to stop the research and evacuate in a hurry, and then the end of the world came, and natural and man-made disasters continued, so that those who originally knew that there was a spaceship from outer space here almost died, so this place became a secret that no one knows anymore. ”

Li Yiyi took a sip of hot milk tea, and then continued to say to himself:

"Two hundred years after the spaceship was in the dust, someone learned about the ship, and then issued a mission under the name of exploring the pre-apocalyptic research institute, hoping that the mercenary team could find something valuable inside, or take a photo."

So what's going on with that black ball? There is also the black super octopus, if that black octopus had existed for a long time, with its strong strength, it is estimated that it would have been able to come out of the ground and harm the earth a long time ago, but why did Liu Taolin and them come out after they entered the spaceship......
