Although Zhang Yang felt that this matter was a bit strange, he did not further analyze the reason for this question, because for him, on the one hand, it was impossible to find the answer, could it be that he had to travel back to 10,000 BC to find the answer? At the same time, it was irrelevant.

He said to Yang Ling'er: "Ling'er, these monsters should be in this cave, be careful, I will explore the way in front later, you are behind me, don't leave too far, you know." ”

Seeing Zhang Yang's concerned look, Yang Ling'er nodded sweetly in her heart, moved behind him, half-wrapped her hands around Zhang Yang's waist, leaned on his body slightly, and a man's unique smell instantly spread throughout her body between her breaths, and she suddenly felt that the world was soft, and everything else seemed less important.

After walking for more than ten minutes, Zhang Yang found that the light in front of him was not so bright, but its light was very dazzling.

When approaching, the two of them stood stupidly and couldn't speak for a long time, if the preciousness of the night pearl is because of its rarity, it sets off its identity, then the natural cave wall in front of the pure gold inlaid with part of the night pearl is full of a great luxury.

This made Zhang Yang wonder if these caves formed by the rough stones and gold of the Night Pearl, or even the belly of the entire mountain, were a means used by some powerful person to store wealth in that distant world 10,000 years ago.

And the treasure that Big Bear said, the Night Pearl Rough Stone and Gold, should be part of it.

Yang Ling'er grabbed Zhang Yang's arm tightly, and her fingertips had already dug deep into his muscles without knowing it.

"Ling'er! Ling'er!" Zhang Yang shouted several times before she came back to her senses. "Zhang Yang, this is the most gold I've ever seen in my life!" Yang Ling'er's eyes lit up.

Zhang Yang said in his heart, don't say it's you, even the top ten countries with the largest gold reserves can't have seen such a majestic gold treasure!

His mouth said: "It's a lot, but it has nothing to do with us, do you think, such a magical cave, and so many Night Pearl Rough Stones and such a big golden treasure, is it so simple? There must be some mysterious power controlling and secretly watching." ”

He thought of the three guards in the cave under the mass grave, and if there was no here, he would not believe it. Moreover, from the moment he entered the cave, he felt uncomfortable, as if something was monitoring their every move.

Yang Ling'er just got carried away for a while, after all, an ordinary person, who could have seen such a large amount of gold stored and be indifferent.

Hearing Zhang Yang say this, he immediately felt that he was too excited, so he smiled and said: "I'm just looking, comment, if I have so much gold, I won't even be restless to sleep." ”

Zhang Yang looked at her and smiled softly, and reached out to brush a few strands of messy hair from her forehead, with a soft movement. Nod your head in agreement.

He said, "Go inside, go to the end, and if there's nothing, we'll go back." ”

Yang Ling'er sighed. Although I didn't find a monster, it was worth the trip to see such a magnificent treasure.

At this moment, there was a rumbling sound not far in front, Zhang Yang was startled, hurriedly blocked the front, quickly took out the light wave dagger, raised his eyes, and saw that a stone door automatically opened on the stone wall on the right side of the front.

Holding the light wave dagger tightly, he stepped forward cautiously and cautiously. The cave that appeared in front of me was also a square cave formed by gold, but the hole was obviously shallow, and the end could be seen at a glance.

I couldn't help but breathe a sigh of relief. With Zhang Yang's current eyesight, he can't imagine the vision of a normal person. An average person's normal vision should be able to see a human face about 60 meters away, such as eyes, nose, and fingers. But he could see a person blink a few times at a distance of 400 meters. It was only when we reached 500 meters that my vision blurred. Therefore, when I looked inside the cave just now, I found that it was just an idle cave, which was equivalent to an idle warehouse in a rural household, and there was no debris piled up, and no abnormalities were found.

Just when he was going to go in and take a look, he found a box at the end, and he felt a little strange, obviously when he inspected the cave just now, he didn't see this box, and it didn't make sense to say that he ignored it. But no matter what, since you have found a vision, you have to go up and find out. At the same time, he also found that the box in front of him was very familiar, as if he had seen it somewhere.

It is said that this cave is very shallow, but in fact, it is also about 400 meters deep, and compared with what I just came in and from Zhang Yang's point of view, it is naturally very shallow. Pulled Yang Ling'er into the cave, and when it was about 100 meters, Yang Ling'er stretched out her hand and pointed to the front and said, there seemed to be something there.

When he arrived at the box, Zhang Yang completely remembered that it was not the box containing the key to the gate of hell that he had obtained under the water tank of Lao Liu's house! But although the shape and size were the same, the handle on it was made of the original stone of the Night Pearl.

And the box that I had already got in my hands was a handle made of silver.

"What kind of box could this be?" asked Yang Ling'er curiously.

"It's supposed to be for a key. Zhang Yang said.

I couldn't hold back the excitement in my heart. This is the second key that has been found. The big bears searched for nearly 10,000 years and didn't find any of them, but they got two of them effortlessly.

Because he had just sensed that it was a key inside.

"Such a beautiful box is actually used to hold a key?" Yang Ling'er felt impossible, and took a few steps forward to pick up the box, but found that no matter how hard she tried, she couldn't open the box. I can't help but say that it's weird.

Zhang Yang smiled: "There should be a switch, look for it." ”

"It really seems to be!" Yang Ling'er also found a small hole when she turned over the bottom of the box, but she was depressed again. "How can this hole be opened?" ”

"I'll come, I'll come!" Zhang Yang reached out and took the small box, tapped the small hole with his fingers, and secretly used a trace of internal force to impact the button hidden inside.

Before the change, he was also at a loss without tools. Only the sound of opening was heard, and the lid of the box slowly opened.

Yang Ling'er saw that it was indeed a key, and she was interested.

However, Zhang Yang found that the biggest difference between this key and the first one is the difference in the direction of the key, the one hidden in the house is bent left and right, but this one is just the opposite direction, it is a key that bends towards the middle.

Then, out of the hole, I continued straight ahead, but it took another hour to reach the end, but I found nothing, so I returned the way I came, and when I entered the entrance of the village, the smoke was rising from the roof.
