The vast but empty futuristic city above, the mysterious dungeon with simple shapes but engraved with rune patterns below, and what those people found and took with them decades ago, all kinds of mysteries surrounded him, and he had no idea where to start.

After a whole year of tossing in the apocalypse, Lin Cheng's ultimate goal was to find the real reason for the apocalypse, and as he investigated more and more, he found that this apocalypse seemed to have a vague connection with this mysterious race underground, no matter how he investigated, he would eventually be taken to the abyss, a place he had never thought about.

So Lin Cheng later figured it out, where the clues pointed, he himself followed where, at this stage, almost all human beings are still in the bitter sea of half-struggle and half-reconstruction, there are many people who are interested in investigating the mystery of the end times, but there are not many people who really set out to do it, Lin Cheng himself is not an unsung hero who saves people from fire and water, he is so persistent in doing this, just to let himself experience the feeling of peace before the end of the world in his lifetime.

A cigarette, Lin Cheng thought a lot, but then shook his head, he decided, since he had already investigated here, then no matter how difficult the road behind was, he had to grit his teeth and go on!

"What do you think?"

Just when Lin Cheng had just finished refueling himself and was about to continue the investigation, Bai Ling, who had been behind him for a long time, had already walked up to him and asked him with a light smile.

Looking at the indifferent look on Bai Ling's face, Lin Cheng raised his eyebrows slightly, and asked tentatively, "You...... It's okay? ”

"What can I do?"

Hearing Lin Cheng's words, Bai Ling asked him with a strange expression: "Didn't you say it just now, it's just your own guess, and it may not be true." Besides, even if it's true, there isn't even a ghost here now, even if I want to recognize my ancestors and find out what all this is going on, I can't do it, how can I do it if I don't continue to search? ”

"Okay."

Hearing Bai Ling say this, Lin Cheng could only nod in agreement, in fact, thinking about it is like this, although at first glance it may be a little shocked to hear that this is his hometown, but if you think about it carefully, you will find that knowing this matter for Bai Ling not only gives her a sense of belonging, but also the same fog as Lin Cheng.

Pointing to the rune stone gate in front of him, Lin Cheng said to Bai Ling: "It was a guess just now, but now I can tell you clearly, this is indeed your hometown!" I have seen the pattern on this rune stone door on many monsters, these monsters are without exception, their strength is extremely powerful, and at the same time, this pattern is also printed on their foreheads, such as the giant centipede spirit I met behind the rune stone door of the Night Meizu's lair, it has such a pattern on its forehead......"

"That'...... Shall we go in and have a look? ”

Hearing Lin Cheng say that this was indeed her hometown, Bai Ling's heart became excited again, but she was quite able to restrain herself, and after stabilizing her mentality, she couldn't wait to say to Lin Cheng.

"Well, I'm just going to go in and have a look."

Nodding, Lin Cheng stood up from the ground, patted the non-existent dust on his buttocks, and raised his feet and walked towards the rune stone gate in front of him.

At first glance, this rune stone door didn't seem to be much different from what they had seen before, but after entering it, Lin Cheng found that this rune stone door was not opening and closing to both sides like the previous ones, but standing in front of them in a complete piece.

"This ......"

After seeing the appearance of this rune stone door clearly, Lin Cheng frowned, a little distressed.

He had seen the hardness of these rune stone gates as early as when he was in the Night Meizu Lair, and although it had not been exchanged for a Soul Breaking Sword at that time, he didn't think that a Soul Breaking Sword could solve the problem in front of him.

With the idea of giving it a try, Lin Cheng took out the Soul Breaking Sword and stabbed it the stone gate, and the resistance to the hand told him that his guess was indeed correct, the materials used to create these rune stone doors are probably not yet understandable to humans at this stage, although the Soul Breaking Sword belongs to the laser sword, but it still can't help this rune stone door.

"What can I do?"

Even the Soul Breaking Sword had no way to take this rune stone door, Lin Cheng scratched his head irritably, and he didn't know what to do for a while.

And Bai Ling on the side finally couldn't help but ask after watching Lin Cheng's repeated temptations, "What are you...... You don't want to break down the door as violently as you just did, do you? ”

"Or else?"

Hearing this, Lin Cheng glared at her angrily and said, "Do you know that kind of treasure is close at hand but you can't get it?" This should be the third time I've encountered the Rune Stone Gate, but no matter which time, Lao Tzu was blocked out by this broken stone, and he couldn't open it with all his might......"

After thinking about it, Bai Ling tried to persuade Lin Cheng: "I think, since this rune stone door exists, then there is definitely a mechanism that can open it, this place is full of weirdness, and the violent means we have been choosing cannot be regarded as a long-term solution......"

After speaking, as if he was worried that Lin Cheng would be angry, Bai Ling closed his mouth tightly and didn't say a word more.

But Lin Cheng's expression at this time did not mean to be annoyed at all, not only that, after listening to Bai Ling's suggestion, he seemed to think of something in an instant, and couldn't wait to grab Bai Ling's little hand and walk towards the rune stone door, and said as he walked: "You don't say that I forgot, this rune stone door does have a switch, but the little princess of the night Mei clan before I don't know if the strength is too poor or the bloodline is not pure, the door can no longer be opened if it opens a small crack, but you are different, with your current strength and identity, Nine times out of ten, there should be a drama! ”

The more he talked, the more excited he became, Lin Cheng's hand holding Bai Ling became tighter and tighter, and he dragged her to the rune stone door in front of him, raised his flashlight and searched carefully on the door, and then pointed to the inconspicuous pit in the lower right corner and said, "It should be here, you quickly press your palm up and try it!" ”

"Okay."

Finally escaping Lin Cheng's clutches, Bai Ling hurriedly rubbed his wrist, which was about to be pinched red by Lin Cheng, and after glaring at him fiercely, he walked to the pit and squatted down, carefully flattening his right palm and covering it.

"Boom—"

As soon as he covered the palm of his hand, before Lin Cheng could react, a dull sound suddenly came from above the rune stone door, and then, Lin Cheng felt that the ground shook slightly, and the rune stone door in front of him slowly began to rise!
