"This mountain-like boulder is actually empty inside, if it weren't for these demonized bulls smashing this place apart, it would be really hard to find!" Looking at the hole with the big head of the boulder behind Da Zhuang, Zhang Heng said in surprise.

The entrance to the cave is the size of a head, and from the outside it looks pitch black inside, but it looks like there's a lot of space inside.

"Shall we go in and have a look?" Da Zhuang looked at the darkness inside and asked.

"Since we're here, we're sure to go in and find out!" Guo Shenglan said with certainty, this time he thinks that he is to find out the situation of this boulder, and of course he will not give up this opportunity.

So, they used their weapons to break the stones next to the cave entrance, and the hole was enlarged so that in a short time the hole was large enough to accommodate three people. Since it was pitch black inside, they turned on a flashlight, which was the supplies they had prepared before they came, and after lighting it, they went in curiously.

After entering the cave, there is a wide passage, and the stone walls of the passage are relatively smooth, and it looks like it was artificially constructed. However, they were not interested in wondering if this passage was artificially constructed, and continued to walk inside, since there was such a large space in this boulder, there must be something inside.

"There is such a spacious space in such a large meteorite, it doesn't look like it was formed naturally at all, but it looks like it was deliberately thrown here!" Zhang Heng used a flashlight to shine on the surrounding environment and said seriously.

"From the intelligence, we know that meteorites that land around the world have a great connection with global digitization, and I think if we can discover the secrets inside the boulders, it will definitely be of great help to us to find out the reason for the data." Guo Shenglan nodded approvingly and said.

"Have you noticed that the more we go inside, the more our strength is suppressed, I feel that the strength that can be exerted now is by no means more than eighty percent, if there are any strange beasts in this, we are definitely a dead end!" Da Zhuang clenched his fists and felt the suppressed power, and said with some concern.

"This situation has appeared outside the meteorite, I'm afraid there is something in it that we don't know, since it can suppress our power, it should be related to the system, of course, this is just my guess." Zhang Heng thought about it and said to Da Zhuang.

When Guo Shenglan heard Zhang Heng's words, she fell into thinking as she walked, because the situation is becoming more and more unclear now, but it is also an opportunity to get information.

Call......

A gust of wind swept past them, and the three of them suddenly shivered, as if they did not belong to this world. However, even this could not stop them, so they continued to walk for a few minutes despite the chill in their hearts, and finally, they saw a different scene.

On the other side of the passage, in the very center of the boulder, a huge space unfolded in front of the eyes of the three people. The sight in the space instantly attracted their attention, and it was unbelievable.

In the center of the space stands a metal instrument with a complex tripod, and the material of the metal instrument is not clear at first glance. In the center of the metal instrument, there is a large glass sphere, and there are several metal tubes on the glass ball that connect to a table outside the instrument, and on the table is a prismatic crystal that flickers and dims.

These are not things that they are surprised of, what they are shocked is that there is a black hole in front of the glass ball, yes, a black hole with a diameter of one meter, on the other side of the black hole, a huge mouse is struggling to get out of the black hole, to be precise, this is not a mouse, but a fierce beast from another world, just looks a little like a mouse.

Gopher: A level 6 otherworldly beast with agile skills, it can come and go freely in the soil, and its two front teeth have strong lethality.

"This ...... What the hell is going on? How do you look like that glass ball is connected to another dimension! Seeing a gopher emerge from the black hole, Da Zhuang said in surprise.

Zhang Heng and Guo Shenglan were also extremely shocked, this was something they had never seen before, the fierce beasts of the other world could come to the earth through that black hole, no wonder they had encountered so many fierce beasts from the other world before, I am afraid they all escaped from here. The three of them had a headache in their heads, and they didn't understand why this was happening.

After a gopher emerges from the black hole, another one is followed by another gopher, and then the gopher emerges from the black hole like a tidal wave. When they came over, they immediately rushed towards the three people, as if they were treating Zhang Heng and the three of them as food.

"Hurry, stop it!! Otherwise we'll all be eaten by these beasts! Zhang Heng's face changed greatly, and he hurriedly rushed to the black hole and hacked several gophers to death.

Guo Shenglan and Da Zhuang also found that they couldn't continue to let these gophers come out, although the strength of a gopher was very small, but a hundred and a thousand, it was not something that three people could resist. So at this moment, Zhang Heng immediately made a decision to stop these gophers from continuing to come out of the black hole.

Zhang Heng rushed to the black hole first, and the abyss blade in his hand stabbed fiercely at the gopher gushing out of the rotating black hole in front of the glass ball. But when Zhang Heng stabbed at the black hole, an invisible force blocked the Abyss Blade and directly bounced Zhang Heng back, almost causing Zhang Heng to fall.

"No, it can't be stopped!" Zhang Heng continued to try again, but it was still the same as the first time, and it was directly bounced back, and the speed of the gopher gushing out was getting faster and faster.

The gophers that came out crawled towards the three people at a very fast speed, opening their front teeth like sharp swords, wanting to bite Zhang Heng and the three of them to death.

Squeak squeak......

The surrounding gophers are densely packed and make strange calls. Zhang Heng and the three of them faced the attack of the gopher, and did not hesitate to counterattack, these gophers are only level six, there is no pressure for them for the time being, Zhang Heng can kill several with one knife. But the one who killed the front continued to swarm behind.

"It's endless, what the hell is this, you can't even get close to it!" Da Zhuang was forced into the corner by the dense gopher, and said speechlessly.

Zhang Heng observed the black hole while killing the approaching gophers, and he found that the formation of this black hole came from the energy of the glass ball behind it, and this glass ball was connected to the metal instrument at that location, and the metal instrument was connected to the flickering crystal stone on the platform next to it.

Zhang Heng didn't pay special attention to this crystal stone just now, but now if you take a closer look, it's definitely not a simple thing. There seemed to be a stream of liquid circulating in this fist-sized blue crystal stone, and if I guessed correctly, this crystal stone must contain a huge amount of energy, and it was constantly sending energy to the glass ball.

"The reason for this black hole connecting the other world and the earth's space is this metal instrument, and the energy source of this metal instrument comes from that crystal, what we have to do now is to take out the crystal stone, and the speed should be !!" Zhang Heng pointed to the crystal stone on the table, frowned and said.

Then, Guo Shenglan dodged to the stone platform, grabbed the crystal stone and wanted to take it out, but she didn't move at all with all her strength.

"No, I can't take out this crystal at all!" Guo Shenglan shouted at Zhang Heng and Da Zhuang.

Zhang Heng and Da Zhuang hacked a bunch of gophers to death and came to the stone platform, and then grabbed the crystal stone together and prepared to take it away, but they found that the strength of the two people could not pull out the crystal stone. Since he couldn't pull it out, Zhang Heng tried to destroy the crystal stone, but Zhang Heng used the Abyss Blade to attack the crystal stone no matter how he attacked it.

"It seems that this uses a special method to fix the crystal stone here, and the crystal stone itself is hard, not like the material of the earth at all, which is much harder than diamond!" It can be said that the Abyss Blade, which has now reached the yellow level, is already very sharp, and ordinary weapons can't resist the attack of the Abyss Blade at all, but the crystal stone in front of him can't be destroyed at all.

Subsequently, the three of them couldn't get this crystal stone after thinking of all kinds of methods, seeing that there were more and more gophers coming out of the black hole, and the surroundings were already full of gophers, and even many gophers came from the ground to attack Zhang Heng and the three people, the three of them were a little overwhelmed at the moment, if they let the gopher drill over, I am afraid that the three of them would be consumed to death.

Suddenly, when Zhang Heng was hacking to death the gopher, he noticed a few pieces of metal connected to the crystal stone, and suddenly, Zhang Heng thought of a way, since he couldn't take away the crystal stone, then cut off the connection tool connecting the crystal stone, so that the energy of the crystal stone could not be transmitted to the metal instrument.

Bite......

Zhang Heng's abyssal blade slashed at the metal pipe fiercely, but he didn't expect the metal pipe to be broken, but a small gap appeared, and Zhang Heng's eyes suddenly lit up.

"Metal pipes can be broken!"

So, the three of them carried out various attacks on several metal pipes, and after a minute of continuous action, the metal pipes finally broke one by one, and such a hard metal was also a material that the three of them had never seen before. But fortunately, this metal pipe is not as indestructible as a crystal stone, and the efforts of the three people have finally paid off.

Click......

In a cracking sound, the last metal pipe finally broke, and the three of them finally breathed a sigh of relief, but they found that the crystal stone suddenly emitted a burst of strong light, and then the strong light slowly dissipated, and then fell silent, and the black hole in front of the glass ball also slowly stopped rotating, but when the black hole completely stopped rotating, it suddenly rotated in the opposite direction.

Immediately afterwards, the space where Zhang Heng and the three people were located shook violently, and a powerful suction force came from the black hole, and the stones on the stone wall cracked one after another, and Zhang Heng and the three of them could not stand firm at all.

With a whooshing sound, the stones on the ground flew up in an instant and were sucked into the black hole, and some gophers that had just come out of the black hole were also sucked in, and the originally stable crystal stone suddenly fell from the stone platform.

"Hurry up, otherwise we will all be sucked in, this is a space-time black hole, once sucked in, it is likely to be sent to the space-time rift for a lifetime and cannot come back!!" Zhang Heng's face changed drastically, and he stuck the Abyss Blade on the ground and tried his best to control his body, and then roared.

They all realized that they couldn't stay here for long, so Zhang Heng put the instrument and crystal stone that made the black hole into the inventory, and then fled this place as fast as he could.

As they ran towards the exit, the surrounding stone walls cracked more and more, and large chunks of stone fell and were sucked into the black hole......
