Seeing baocao start to dig herbs, Qin Feng's eyes moved again in the stone chamber, but he didn't gain anything from this search. At present, he had to turn his eyes to the bluestone platform.

Slowly, Qin Feng came to the stone table. Qin Feng touched the concave and convex points on the circular pattern. At the beginning, it was a little warm. At present, he couldn't help wrinkling his eyebrows. After a long time, he could still maintain the temperature. This is obviously not an ordinary stone table pattern. There should be some mystery on it.

"Now that thing hasn't appeared, is it related to the patterns?" Qin Feng frowned slightly and stared at these patterns.

"Nuo, I'm not greedy for one third of you." after picking up all the herbs, baocao handed one third to Qin Feng, looked at the pattern on the stone platform and asked, "what's the matter? Do you find anything?"

"I can't see." when he put away the herbs, Qin Feng shook his head and stared at the concave convex patterns with locked eyebrows: "but I guess the thing you said should be related to this pattern. If you want to get that thing, you have to crack this pattern first."

When Bao Cao heard the speech, he nodded his head, opened his eyes and kept moving on the pattern. Suddenly, he opened his eyes and said to some surprise, "do you see the small holes in the four corners? Do you need any keys?"

"Key?"

Looking at the small holes Bao Cao said, Qin Feng nodded and immediately scanned the whole stone room. His moving eyes finally stayed on the dead bones behind the stone table. His eyes moved down, but his eyes were bright. He saw four slender black keys hanging on the bones in the palm of the skeleton's hand.

"There it is." Qin Feng pointed to the four keys in the palm of the skeleton's hand and said to Bao Cao.

"Try it quickly." Bao Cao hurriedly said, and reached out to push Qin Feng.

After Bai baocao glanced, Qin Feng didn't bother to worry about anything with the little fool. He came forward and looked at the dead bone. He felt a little empty in his heart. After closing his palms, he saluted respectfully. Only then did he carefully grasp the key and gently pull it.

"Click..." because of the years, the withered arm was pulled off by this small force.

"Elder, I have offended you!"

Looking at the broken bone arm, Qin Feng smiled, bowed to the dead bone again, and then picked up the bone arm from the ground to connect it.

Holding the bone arm in his palm, Qin Feng suddenly picked the tip of his eyebrow. He noticed that there seemed to be something wrong with the weight of the dead bone in his hand

From the corner of his eye, he swept the grass that was carefully studying the pattern. Qin Feng secretly glanced at the bone arm in his hand. His eyes looked through the fracture above, but he found a faint discovery. In the bone gap, it seems that there is a small gray white iron sheet. The color of the iron sheet is close to the bone. If he is not careful, it is really difficult to find it.

Looking at the looming gray iron sheet, Qin Feng swallowed a mouthful of saliva, his fingers almost involuntarily extended in, then took it out quickly, finally threw it into the ring like lightning, and then took down four black keys solemnly.

After finishing this, Qin Feng was relieved, kindly wiped the dust off his bone arm, and then eagerly returned it to his master.

Throwing away the black key in his hand, Qin Feng smiled and walked slowly to the stone platform.

"Well, have you got it?" he asked, staring at the pattern on the stone platform without lifting the straw head.

He smiled and nodded. Qin Feng divided two pieces of grass, and then they put four small keys into the small holes in the four corners together.

"Click!"

With all the four keys inserted into the pattern, the pattern on the stone platform suddenly creeped up strangely, and a faint light burst from the pattern and shone on the stone chamber.

Narrowed his eyes, Qin Feng stared at the luminous pattern. Under his gaze, there was a clear sound on the stone platform, and then the pattern center slowly split and spread around.

Seeing this, Qin Feng came quickly and took a few steps back.

The pattern crack spread to the edge of the circle, and then it stopped slowly, revealing a dark hole with a diameter of nearly two meters.

The strange situation made Qin Feng frown. He didn't dare to check it for a moment. After waiting for about a few minutes, there was no abnormality. Then he carefully approached the stone platform.

At this time, on the stone platform, the pattern has disappeared, revealing a large dark hole. The hole is dark, faint and has a cold smell. It floats up from the black hole, which is a little strange.

Qin Feng picked up a small stone on the ground and threw it into the black hole. A moment later, there was a sound of stone collision.

"About fifty meters deep." he whispered after thinking for a moment.

They looked at each other for a moment and nodded. Although they felt strange about the black hole, their goal was that kind of thing. They definitely wouldn't go back if they hadn't got it yet.

When they were about to enter the cave, Qin Feng suddenly turned around and went to the corner to collect all the gold coins and property into the ring. Then he turned back and was ready to enter the cave.

"Don't look at me like that. These belongings may not be of much use to you core students, but they are quite precious to me as a worker." ignoring Bao Cao's disdainful eyes, Qin Feng said faintly.

Bao Cao was afraid and said, "I don't know what will happen next. You should protect me."

Looking at her timid stupidity, Qin Feng wanted her to wait on it, but he also knew that Bao Cao would never agree. Fortunately, he didn't say it, lest she thought she wanted to steal it.

The body shook slightly, a flame emerged, wrapped the two people, and fell rapidly in the dark black hole.

At the moment of interest, the soles of their feet fell steadily on the ground. After reaching the bottom of the cave, they found that the black hole was like a straight channel. The bottom of the cave was the same as the hole, only two meters square, surrounded by hard stone walls.

"There should be a mechanism or something here."

"Look at the situation first. Don't hurry." Qin Feng shook his head and pulled Bao Cao in a low voice.

"There are walls all around here. There is no danger." Bao Cao reluctantly shook his head to the cautious Qin wind with some plants and plants. "You are too timid. Do you need to be so careful? I thought you were very powerful before. I didn't expect you to be so timid."

Qin Feng didn't bother to pay attention to Bao Cao's sarcasm. He looked around and explored the situation here little by little

"Find out if there is a mechanism nearby." a moment later, nothing was found. Qin Feng went to a corner of the wall and began to explore.

Seeing this, Bao Cao also automatically went to the other side, and the jade hand fumbled for the wall and looked for the mechanism.

"Found it."

After a few minutes, there was a slightly surprised cry from the bottom of the black hole. Qin Feng took back his palm and smiled helplessly. This woman really has a set of mechanisms.

The jade hand was placed on a dark grid under the wall and exerted a slight force. The dark grid sank when it was dark, and the bottom of the cave vibrated slightly. Immediately, the wall in front of the grass was slowly lifted up at this time, revealing a hole two meters high and one meter wide.

At the moment of pressing the dark grid, the stupid baocao hid behind Qin Feng smartly, then poked out his head and looked at the slowly opening wall.

There was a hole at the bottom of the black hole. Qin Feng stared at the hole. Behind the hole, there was a dark channel with no end to see. The walls on both sides of the channel were inlaid with small moonlight stones. However, due to the large spacing of moonlight stones, the light of the channel was very dark. His eyes were cast on the past, and the edge could not be seen in the dark.

"Qin Feng, there seems to be some danger here." he leaned out his head, looked at the endless passage and whispered. It seems that she, who is cute, is also aware of some unusual things.

Looking at the channel with slightly frozen eyes, Qin Feng frowned. His instinctive intuition told him that at the end of the channel, it might be the destination of their trip.

But similarly, his intuition also reminded him that deep down at the end, there were dangers.

However, since he has formed a team with baocao, it is for the kind of thing she says, so he has long understood that if he wants to get this thing, there must be a crisis of life and death.

Now that the decision has been made, there is no need to hesitate.

"You can't look back when you've come here. Let's go." Qin Feng sighed lightly. He didn't hesitate any more and walked into the channel.

Bao Cao hesitated for a moment and quickly followed.
