The unknown is often the most terrifying, we don't know what we will face next, and we don't know what kind of countermeasures should be formulated, so we can only rely on courage to move on, on the way, we found a lot of footprints, there are some blood stains on the walls, and no one can be sure what happened to the people in front of us.

The atmosphere was rather dreary, and the silence was unusual, except for the sound of fragmented footsteps ringing in my ears, echoing incessantly.

After about two hundred meters, we stopped again, this time not because we were tired, but because we had reached the end of the cave, which was a semi-circular cave, the top of the cave was in an arc, like an inverted bowl, but the arc was not regular, and it looked simple and vicissitudes.

This is also the birthplace of the underground dark river, when we walk towards this cave, the sound of the water becomes clearer and clearer, the surging water is like a cone-shaped funnel, from wide to narrow, and gradually extends to a blue-gray stone door, this master door is about three meters high, two meters wide, the light shines up, uneven, the surface is a layer of powdery stone chips, mottled to the shape, touch with your hands, all weathered stone powder.

There are still some stone carvings under the stone powder, but because the age is too old, these stone carvings have been weathered, completely unclear, the footprints stopped after coming here, and the blood stains no longer appeared, we continued to look along the stone wall, looking for a long time, but still no gain.

Zhang Qiang said with a strange expression, "It's really strange, why did the footprints disappear when they came here, could it be that all those people were eaten by monsters?" ”

Saying this, everyone's hearts beat faster, and it was difficult to sit still, and Anzanji shook his head and said that there was no such possibility, even the most powerful monster could not have done so many people silently, and if there was really a massacre here, there should always be a trace left, but we have not found such traces from beginning to end.

Zhang Qiang was puzzled, "But how can so many footprints disappear for no reason, are these people invisible?" ”

As soon as he finished speaking, a young warrior came running and pointed to the underground channel and said, "They must have climbed into the dark river channel, and I found some ropes on the edge of the channel, and many traces of being pried!" ”

Hearing this, we subconsciously ran towards the place that the little warrior said, the end of the dark river waterway is on the left side of this stone gate, it is a very shallow and narrow opening, Chen Hu stretched his arm underneath to probe, seemed to sense something, turned back to us and said, "It's very deep, it is estimated that the waterway is the only way through the stone gate, these people have already escaped by the waterway one step ahead of us, should we go down?" ”

After speaking, Chen Hu turned his gaze to me, after so many things, An Zanji and I seem to have become the backbone of the whole team, Chen Hu will ask for our opinions before making every decision, and he doesn't dare to mess around casually.

I groaned for a moment, and instead of speaking immediately, I looked at Anzanji and asked him what he thought. Anzanji was still silent, but his eyes were not fixed on the waterway, but still stared at the gray stone door, and what was flickering in his eyes was unpredictable.

Seeing this, I gently patted Anzanji and said what do you want? Anzanji was stunned for a moment, then came back to his senses, pointed to the dark river channel on the side, and said that it is too dangerous to cross the waterway, we don't know the situation below at all, in case this hole is very long, wouldn't everyone suffocate in it?

Chen Hu was a little annoyed, scratched his head and said, "Didn't someone pass through this waterway in front?" Presumably, it should be possible, and we are already trapped here, there is only one way out of the cave, what if we don't take the waterway? ”

Anzanji said that he had a better choice, then stood up and pointed to the dusty stone door in front of him, Zhang Qiang and I were stunned, and hurriedly said, "No, we don't have tools to dig holes, and such a thick door, even with tools, it may not be able to break open, unless we use **......"

Chen Hu hurriedly shook his head and said, "You can't use **, it's too dangerous, not to mention that the ** explosion may disturb the 'monster' in your mouth, such a violent explosion is likely to cause a chain effect, in case it causes collapse, it can be ......"

"Don't bother." Anzanji still shook his head and said, "I have a guess that maybe we can call this door without destroying it." ”

"How is this possible?"

Zhang Qiang and I both exclaimed, not to mention how thick this stone gate is, the height of nearly three meters alone is enough to make people daunting, the entire stone gate is connected to the cave, not to mention the weight of dozens of tons, or even hundreds of tons, even if a few of us are superhumans, we may not be able to open this stone gate.

Anzanji said that in fact, we can choose a gentler way, relying on brute force is definitely not possible, but you see, on the right side of this stone door there is a huge relief, although the relief has been oxidized, and it is impossible to see the original appearance, but the eyes are very protruding.

I looked in the direction of his fingers, and sure enough, I saw an eyeball-shaped pit, about the size of half a fist of an adult, and there was another layer of relief under the pit, showing a wavy pattern, very mysterious, and there was a miniature dot in the center of the pattern, I don't know what it was for.

I groaned and rubbed my chin, "What is this thing for, you know?" ”

"I'm just guessing!" Anzanji slowly walked to the vicinity of the pit, frowned and observed, and let out a soft groan from his mouth, "If I expected it to be correct, this and the pit is equipped with a mechanism to open the stone door, in ancient times, this stone door should have been used for sacrifices, after passing through the stone gate, there must be a cave, this should be an important altar of the ancient witch clan." ”

Zhang Qiang and I were silent and continued to wait for Anzanji's next words.

Then, he continued, "But the altar is a very sacred and important place, not all the people are qualified to enter, all of them will build this stone gate, except for special people, no one else can activate the mechanism of the stone gate. ”

Chen Hu said, "But there is nothing in this dent, even if there is a chance, I am afraid it will be destroyed long ago......

Anzanji waved his hand and said, "No, it's still there, but we don't understand how it works. "Do you know how it works?" ”

Anzanji smiled and said, "Actually, I don't know, but I have a conjecture in my heart." ”

With that, Anzanji winked at me mysteriously and motioned for everyone who was behind him to step away. We did as we said, but the doubts in our hearts deepened, Chen Hu wanted to say something, but I interrupted, although I didn't know Anzanji's intentions, but I was very confident in him.

Under all the nervous gaze, Anzanji put his hand in his arms, and then slowly felt a small purple-black crystal, and when I saw what it was, my whole heart trembled.
