This entire tall and magnificent mouse city has more than 30 floors, and this castle is the crystallization of the wisdom of the Itchy Rat Star. Unfortunately, the Itchy Rat Star Star who built such a magnificent building eventually disappeared into this world, and an alien race disappeared without a trace.

To the east of the Mouse City, it was originally a prosperous and complete town of earthen houses. There were originally some people living in the Itchy Rat Star who were surviving to avoid disasters. Unfortunately, all the alien races have been destroyed now.

In fact, aside from their special identities, the rat star is not different from our humans. Everyone is for survival, but the home where we humans live is still good, but the rat star they are affected because a planet called alien planet exploded next door, and their rat star was also affected. So in order to survive, they had to migrate to take refuge.

Unfortunately, they died on our planet in the end, and Tang Fan probably knew about the process of the rat star being exterminated. It is said that the rat star being exterminated because of a strange mirror, and it is also said that the mirror contains a substance called "black energy", that is, the mirror that doesn't know where it is is a very dangerous thing.

After about twenty minutes, Tang Fan and Lao Gu left Tufangzi Town, they happened to arrive in front of the Great Stone Gate of the North Palace in the northwest of Tufangzi Town.

Tang Fan took a look and found that the big stone door in front of him was an extraordinary skill! The visual height of this stone door alone was enough to reach about six meters! The width of both sides of the door was as long as four meters! Lao Gu suddenly felt nervous when he looked at the door.

Lao Gu lived for half his life. In addition to being trapped in a mass grave, he had also been engaged in related research on ancient creatures before. He had also seen many magical ancient relics, such as the tomb of an emperor, the tomb of a certain official, and so on. By the way, there is also a tomb hidden in a different dimension space.

This is the first time Lao Gu has seen the dungeon ruins like this in front of him. Not only that, from the cave on the edge of the cliff, the crushing traps that make you numb when you think of it, and the body of the itchy rat prince that appeared in the mysterious stone chamber, these are rare and important appearances in human history! However, it’s a pity...

Unfortunately, Lao Gu is now trapped in the mass pit of Purgatory Island. Not to mention Purgatory Island, it is a major issue to say whether he can leave the mass pit!

So at this moment, right in front of the stone gate of the North Palace, Lao Gu put the eternal light in his hand aside, then he put his hands on the stone gate, and then used his power to push open the stone gate with his own strength.

Tang Fan stood beside Lao Gu. He looked at Lao Gu so hard that he suddenly felt funny. About three minutes passed, Lao Gu was still pushing the stone door hard, but the stone door did not move at all. Tang Fan shook his head speechlessly and said, "Lao Gu, don't waste your energy. This stone door looks like it weighs at least a thousand pounds. With just a little strength on your body, it would be a fantasy to push open this stone door."

"Oh, I'm old, and my body is useless..." Hearing this, Lao Gu, who was just trying to try, suddenly turned red in his face, and then he continued, "Zero Yi, don't just talk sarcastic, hurry up and take a hand. Do you think my old bone can push the stone door open? This is impossible. The stone door is so heavy, and only a young person like you have the strength."

"..." Tang Fan was speechless.

After all, Tang Fan was Tang Fan, who was about fifteen years old at this time. He was not a young man at that time. At most, he just thought he was a young man. Even if the fact is this, even if Tang Fan really faced a group of adults in the future, he could easily knock him down with the power of hsL serum in his body.

Then, Tang Fan activated the power of hsL serum to strengthen. Although it was only opened to a certain extent, it was enough. At this moment, Tang Fan put his hand on the huge stone door. However, Lao Gu, who was beside him, saw that he pushed open the seemingly indestructible stone door with just one hand, and he was not struggling to see his appearance! Lao Gu couldn't help but feel a burst of admiration in his heart.

After a while, the huge stone door was pushed open by Tang Fan in two chapters, easily and bravely! Lao Gu couldn't help but give Tang Fan a thumbs up, and then flattered him: "Wow! I really didn't expect you to be so powerful, kid! I think you are just a young man, you can have such great strength at such a young age. Could you be born with divine power? I heard that since ancient times, there has been many ancient people born with divine power, such as in that certain Romance, there is a Lu Fengxian who is known as the world's unparalleled one. I'm afraid your strength is on the same level as him!"

"..." Tang Fan had no expression on his face and no turmoil in his heart. Even if he was praised for being able to challenge Lu Bu, he would not want to laugh. Because when he got this power, it was not what he was willing to get. If he had not been forcibly injected with something called hsL serum modification agent, maybe he should have been spending his childhood happily with Man Mengmeng and Bai Ruoshuang at this moment, right?

Unfortunately, luck makes people feel bad. Who would have thought that he was taken away by an old man who claimed to be Qingtang. What happened next was not something he could decide. It was like he was arranged by fate, and no one could change it.

At this time, the big stone gate of the North Palace had been opened by Tang Fan. The interior of the North Palace was dark, and it could even be said that it was black without any fingers.

Lao Gu quickly picked up the eternal light on the ground. He did not walk in immediately, but instead carried it inside to look at it. However, the eternal light could illuminate it with a limited range, so no matter what he did, it would be in vain.

However, for Tang Fan, he does not need any eternal lights or other lighting tools. At this time, the abilities given by hsL serum can come in handy. In the visual enhancement in hsL serum, there is a ability called night vision ability, which allows him to see everything in the night clearly!

Then, everything in the North Palace was brought into sight by Tang Fan at a glance.

Tang Fan glanced at the ground and found that the distance between the ground extending to about five meters was a crack, and the crack was very wide! If you look at it, it was about thirty meters long.

Lao Gu, who was standing beside him, saw Tang Fan's starry eyes scattering a crystal light that was hard to sense in the darkness. He probably knew that this was Tang Fan's ability, so he continued to ask: "Zero Yi, how about it, have you seen something inside?"

"Five meters!" Tang Fan said lightly.

Upon hearing this, Lao Gu suddenly felt confused, and then he continued to ask, "Zero Yi, what did you say just now? What five meters? What did you see?"

"There is a crack in front of the five meters. This crack is about thirty meters long. Let's go in and take a look first. Be careful not to walk in front of me." Tang Fan replied lightly, then walked in front of Lao Gu, and first Lao Gu entered the North Palace.

Then, Lao Gu quickly followed Tang Fan's footsteps.

After walking about five meters, Tang Fan suddenly stopped, and Lao Gu, who was standing beside him, quickly stopped. Because he had just heard Tang Fan lift the crack, he was worried, so he continued to ask, "Zero Yi, have you seen something again?"

"You will know if you look down..." Tang Fan said speechlessly.

Lao Gu quickly took the eternal light in his hand and shone it downwards. He was so scared that he quickly took two steps back. Just like that, he was standing on a seemingly cliff-like ground. If he took another step forward, he might have to fall down!

Lao Gu, who had just left the cliff, suddenly breathed a sigh of relief and continued, "Zero One, is there a cliff below? The crack you just said was so big, thirty meters. I thought you were joking, but I didn't expect it to be true!"

"..." Hearing this, Tang Fan was speechless, thinking that he would use this kind of thing to deceive you? Besides, there is an abyss cliff below. If you fall down, I can't save you.

But at this moment, Tang Fan now had a staircase on the side, and then he looked around. The situation in the North Palace is as follows: there are only two roads around, the first road is the right road ahead. However, because there is a long crack in the middle of this road, Tang Fan and Lao Gu cannot pass for the time being. Next is the second road, and there is also a staircase here. Tang Fan took a look and the staircase seemed to be well preserved. Perhaps that would be the only road he and Lao Gu could move forward next.

However, just as Tang Fan was observing the terrain, several figures appeared opposite the crack. Lao Gu saw two bad fires on the opposite side. It seemed that someone was holding a torch. Lao Gu looked at Tang Fan in surprise and said, "Zero Yi, there seems to be someone on the opposite side! Look!"

"I saw it." Tang Fan happened to appear at this moment. He turned on the visual enhancement of hsL serum, and then said to Lao Gu on the side: "Don't make a sound, they don't seem to show us, so quickly turn off the eternal light."

"This..." Lao Gu was stunned. The eternal light was his only lighting tool at present. If it was turned off, he would not be able to see anything.

When Tang Fan saw Lao Gu's appearance that he was reluctant to turn off the lamp, he was speechless. If their identity was exposed at this moment, it would probably be very unfavorable to them, so Tang Fan could only extinguish the Eternal Light for Lao Gu.
Chapter completed!
