Could it be that a dagger needs to be put in this groove?

The size of Dayong's dagger is exactly two fingers wide and seven inches long, of course, there are some cases, some people will build daggers according to the size they think fits, but most daggers are made according to this standard.

"Maybe it's not a dagger, but just an object about the same length, width, and narrowness as a dagger?"

Qin Dai pondered for a while, and suddenly glanced at the black magic battle a few more times, and a dazzling smile immediately appeared on his lips, "Can you see what this magic staff is made of?" ”

Murong Jing said: "It should be Xuantie." ”

"Oh, you know?" Qin Daixin exclaimed, Xuantie is a meteorite to put it bluntly, it comes from outer space, it is hard and abnormal, and it is rare that Xuantie is extremely moldable, and under the continuous action of high temperature, it can be dissolved into water and calcined.

She thought that Murong Jing, an ancient uncle, didn't know about Xuantie!

Murong Jing chuckled, and actually stretched out his hand and rubbed it on the top of her head, "Silly girl, I don't know what you know?" ”

Qin Dai secretly discussed it in her heart, there are really things I know that you don't know, do you know what the plane looks like? Will you use the AK-47? Have you ever watched TV and drunk XO?

Alas, the ancients, who were shallow in their knowledge, thought they knew everything......

Straight to the point.

"You said that this magic battle is made of dark iron, and the key in the lid of the sarcophagus is also made of dark iron, so will the things needed in this groove also have to be made of dark iron?" Qin Dai was thoughtful.

"Quite possibly." Murong Jing smiled bitterly, "Xuantie is already rare. It is even more rare to make the key in this sarcophagus, but unfortunately we don't have enough chances, thanks to your blessing, we have the opportunity to open this sarcophagus. "Twelve hours are coming, and when the waters rise, they are afraid that it will be difficult for them to get out.

Qin Dai smiled in her heart. looked very heartless, "If we can't get out, let's just lie in this sarcophagus, even if we die, there is also a shrouded thing." ”

Who knew that Murong Jing nodded solemnly, "It's exactly what I want, life is not the same as death, no matter how good it is." His eyes were as bright as they were when he first saw them. The darkness is incredible, and if you look closely, you can see that the black pupils are full of her figure.

Qin Dai's eyes were slightly hot, she never thought that she would have such a love, there would be a man like Murong Jing, who was willing to live with her and die with her.

As he said. Even if you can't go out, you can sleep here with your most beloved person. It doesn't count!

Qin Daixin took the initiative to take Murong Jing's hand and said, "Desperate place again, we haven't reached the last step yet!" As soon as she lifted her legs, she pulled out Leng Feng from her boots, handed it to Murong Jing and said, "Look at this, I got it by accident, and I don't know if it's the key." Although she said this, she didn't know why, she had already decided in her heart that Leng Feng was the second key.

Murong Jing carefully looked at the dagger in his hand and started deeply. This dagger is black and black, and has not yet been bladed, but it is more than two fingers wide and seven inches long, and it is made of dark iron.

"You girl, where did all this stuff come from?" When Qin Daixin took out the first key, he was already surprised enough. also secretly admired this girl's good luck, she got such a treasure thing by chance, he only thought she was lucky, but he didn't expect her to come up with one.

Perhaps, there is still a way forward? It's a coincidence to get one, but it's not as simple as luck to get two.

Maybe it's fate.

Whether you can go out or die here, with her by your side, you have no regrets in your life, right?

Murong Jing smiled, squeezed her hand and said word by word: "Whether you can go out or not, I will accompany you, don't be afraid." He was like soothing a child, and his words were incredibly gentle and incredibly gentle.

Qin Daixin nodded and smiled at him.

The two came to the edge of the sarcophagus, and Murong Jing gently put Leng Feng into the groove.

The size was appropriate, and Leng Feng lived up to expectations, submerging into the groove seamlessly, leaving only one handle outside the groove, but in response to their expectations, it was a piece of tranquility.

Nothing happened! There is no imaginary glow, and there is no violent shaking that makes people feel shocked.

As if nothing had happened.

The two looked at each other and couldn't help but feel a little disappointed.

Qin Dai was unwilling, and said, "You try to take the Fa Battle and see if you can use it." ”

Murong Jing held the Xuantie Law Guard again, and lifted it vigorously, but he didn't expect to pick it up all at once.

The two were overjoyed.

"Picked it up? It seems that Leng Feng is indeed the second key. I just don't know where the way out is. "There is really nothing more coincidental in this world, the two favorite weapons in her hand are the keys to open the secret of this sarcophagus, and she got these two treasures by chance, but she didn't expect to be saved by them in the end.

Her sixth sense is really accurate.

Murong Jing looked carefully at the magic battle in his hand, and the more he looked at it, the more he felt that it was not ordinary, and the strange thing was that he didn't see a trace of killing and bloodshed in the magic battle, but saw a soft light through the darkness.

What's going on?

Qin Daixin felt strange in his heart when he saw him quietly staring at the magic battle in his hand, but Murong Jing's expression was too strict, Qin Daixin had never seen him like this, and he muttered in his heart.

At this moment, the soft white light above his head suddenly dimmed, and then he heard an uplifting "boom" sound from the sarcophagus.

The two of them didn't care about anything else, and hurriedly stepped forward to check, only to see that a black hole suddenly appeared at the bottom of the originally tight and impermeable sarcophagus, and the hole was not wide, barely allowing one person to pass through. Murong Jing jumped into the sarcophagus with the Dharma Battle to check, and saw that there seemed to be a faint light in the black hole, and the stones inside paved the road, and there seemed to be the sound of water.

"Go, go down."

Vitality is just around the corner, and there's no reason not to go down.

Qin Daixin hurriedly jumped into the sarcophagus, and the two groped their way into the hole, and walked forward along the stone road one after the other. Beneath their feet were bitterly cold water and neatly cut stone strips, all of which had been cut by hand. One by one, the terrain is getting lower and lower, and these stone strips are naturally arranged in a stepped pattern. Murong Jing and Qin Daixin could see more and more light, and above their heads was a dome-like natural cave with plants whose names they didn't know. Occasionally, bats can be seen hanging upside down in the dark of the cave.

Murong Jing walked in the front with the Dharma Battle, he held Qin Daixin's hand tightly, the warmth and strength from the palm made Qin Dai's heart feel at ease, she has never been a person who likes to rely on others, at this moment, Qin Daixin suddenly had the idea of wanting to rely on it.

Neither of them spoke, so they pulled forward, and their speed was not fast. The cave was dark and slippery, and there might be hidden dangers in the cave, so both of them deliberately slowed down to keep an eye on the dangers lurking around them.

It was precisely because of this that when the amazing loud noise and the shaking of the earth behind them came, Qin Daixin and Murong Jing were stunned and almost unable to stand.

The two continued to support each other, plus relied on the Xuantie Law Battle. barely stood still.

Small rocks kept rolling down the roof of the cave, and the originally quiet bat seemed to be frightened. fluttering and flying.

"What's going on?" Nima, just escaped, what's the matter, is it going to be an earthquake now, or a tsunami, anyway, you are not willing to shoot your sister to death in it, right?

The shaking continued, and it was difficult for Qin Daixin to guess wildly.

"The place we were staying in just now must have collapsed, and if I'm not mistaken, it's going to be here soon. Come on. ”

Qin Daixin was convinced of Murong Jing's words, this innate trust sounded like a joke.

The two hurriedly fled forward.

In the face of landslides and ground cracks, an escape word is very suitable. It is precisely because of the overwhelming posture behind them that they believe that the front is the exit, and it must be safe.

Situ Langxing is a handsome man, and he will never bury the successor he has been waiting for so hard here, since there is a destructive collapse behind him. The front is naturally safe.

The wind under the feet of the two of them, so that they ran towards the road with all their strength, and vaguely, they seemed to see a hole in front of them, and then the light suddenly shone in, making people's eyes hurt.

It's out!

Murong Jing and Qin Dai were overjoyed, and the two of them held their hands tightly and ran forward vigorously.

After staying in a dark place for a long time, how could you stand such a dazzling light! Fortunately, Murong Jing and Qin Daixin were both experienced people, and the two of them ran forward a few more steps with their eyes closed, and waited until the stinging pain in their eyes dissipated a little, before they opened their eyes and looked around.

They have already gone out of the secret passage, the surrounding area is extremely empty, the eye is a piece of green, the place where the two of them are standing is slightly low, the exit of the secret passage is an inconspicuous cave entrance, no matter who looks, they can't imagine that there is a cave inside.

In the distance were rolling mountains, and behind them were a vast cloud of dust and mountains that had been changed beyond recognition.

The cracks have stopped. In this way, even if someone finds this cave that has not yet collapsed, they will not find anything, and the mysterious cave, the delicate mechanism, and Situ Langxing's coffin will all be turned to dust.

Qin Daixin looked at the huge waste area, and couldn't help but sigh, what kind of power is this, it can shake the mountains and the earth, the twists and turns of the tunnel, the design is so exquisite, and the stone strips that are cut squarely, the length and width are almost exactly the same, there is no time to build such a secret passage? If it weren't for the iron box with body temperature in her arms, if it weren't for the black staff in Murong Jing's hand still shining in the sun, she would have thought that this qiē was all an illusion.

"Let's go, this mountain is collapsing a lot, someone will come to check it soon, we have to get out of here quickly."

Qin Daixin nodded, those mysteries are waiting to be solved little by little in the future!

The two of them glanced at the collapsed mountain again, and then found their way down the mountain.
