After examining the bones on the ground and seeing that there was nothing else in the small square, the team returned to the gate.

When they checked the gate before, no one could find a way to open it. The two tightly closed doors were closed very tightly, and the doors were unusually heavy.

Chen Ziyang still focused on the relief pattern above the gate, thoughtful.

Liu Cong and several of his men dangled in front of the gate, and then they came to the conclusion that if they wanted to open the gate by violence, they couldn't do it with the team's current conditions.

Because the number of people in the team is relatively small, and the explosives carried are relatively small, these explosives do not have much power at all when they blast on the surface of the gate, and it is estimated that the two gates cannot be opened, so Liu Cong walked to the side and stared at the city wall next to the gate.

"You don't have to research, these walls can't be blown up." Guessing Liu Cong's idea of starting these city walls, Chen Benzhong hurriedly spoke to stop it.

"The thickness of these walls is unimaginable, and most importantly, if I am not mistaken, they and gates cannot be destroyed at will.

This underground palace was built directly in the crack of the mountain, with the top of the rock and the ground below, and the heavy wall seemed to be like a load-bearing beam, holding up the weight of the mountain above, which should have been deliberately done during the design and construction.

When the entire underground palace is completed, the weight of the mountain above is completely pressed on the city wall, and with some mechanisms in the city wall, if the gate and the city wall are damaged by external forces and collapse, the entire mountain will collapse.

This is tantamount to the best anti-theft mechanism, completely eliminating many methods of stealing and digging. With such a big hand, the people who designed this place are definitely not trivial, and it was not easy for this dungeon to be built. It's really hard to imagine that this underground palace was built hundreds of years ago. ”

"This ......" After listening to Chen Benzhong's words, Liu Cong reacted, no wonder the long city wall that everyone passed by before looked very strange, especially those brick joints, which gave people a very strange feeling.

Now that I think about it, these bricks are stacked in a very special form, like building blocks that are spliced together, if a few stone bricks are really pulled out of the city wall, then the remaining stone bricks will fall downward, and the whole city wall will collapse from the gap like a domino that has been knocked down.

"Don't think about being opportunistic, be sure to find a way or mechanism to open the door, and you can check around."

Chen Benzhong was extremely depressed, and he tried his best to come here, but he was blocked in front of these two gates, and it was difficult to enter.

"I'll try, I seem to have guessed how to open the door." Chen Ziyang said as he slowly stepped forward and came to the tightly closed door.

When observing this gate before, Chen Ziyang found a relatively incongruous place. The height of this gate is very high, almost the entire mountain crack, and the upper and lower ends of the gate are level with the top and bottom of the mountain crack, at least five meters high. But the pattern on the gate is very small.

The swastika pattern formed by four dragons protruding from the steel gate is not very large, and it is not placed in the center of the gate, but in a lower and left position.

Such a large door, but with such a small pattern, and at the same time the pattern is not in the very center of the door, which causes the pattern on the door to give people a sense of inconsistency.

Chen Ziyang has seen this pattern countless times, and it can be said that it is very familiar, and he is 100% sure that in the center of other patterns, there is no such thing as a dragon ball.

The ball-like ball was located in the center of the four dragons, protruding from the gate, about two meters above the ground, and a person standing on the ground could touch it by reaching out his hand.

Judging from the form in which the ball was placed, Chen Ziyang guessed that it was very likely that the ball was placed here on purpose, so that people could touch it with their hands.

"Get out of the way, be careful I touch the mechanism." Seeing that the others flashed to a safe corner, Chen Ziyang stretched out his hand and pressed a few times on the bulging ball in the middle of the four dragons, but the feeling of his hand was very firm, and there was nothing unusual about this ball. It doesn't look like it's going to be pressed down.

Then he changed his method and pushed the spherical protrusion to the side, which was like a cover on the mirror of an anti-theft door, and suddenly slid to the side, revealing a pitch-black hole.

A strong gust of wind blew out of this pitch-black hole. Looking at the size of the hole, Chen Ziyang had an idea in his heart, he turned around and said to Chen Benzhong on the side: "Borrow something." ”

Seeing the round hole on the door that looked like a keyhole, Chen Ziyang knew that his previous guess was correct, the size of this hole seemed to be slightly larger than the pearl that everyone found before, and it should be just right for the pearl to pass through.

"Borrow something?" Chen Benzhong frowned, listening to Chen Ziyang's meaning, it seemed that if he wanted to open these two gates, he needed something on his body, this was really strange, how could the key to open the door be on his body.

"Yes, give me the great pearl you just found, I think that pearl is the key to opening this door."

"Huh?" Hearing Chen Ziyang's words, the people around all shouted out in surprise.

"Oh? Pearl ......" Chen Benzhong's eyes lit up suddenly. After hearing the word pearl, Chen Benzhong instantly realized a lot of things, he felt that Chen Ziyang's method was correct, so he opened the box without hesitation and handed the pearl to Chen Ziyang's hand.

"Wait! For the sake of caution, let's take a look at the situation inside the round cave first. Liu Cong was very cautious, although this pearl was worth a lot of money, but it was nothing in their hearts, he did this for Chen Benzhong's safety, hoping to check what was in the hole in advance.

"It's fine." Although Chen Ziyang was confident, he couldn't refuse Liu Cong in a word, so he retreated to Chen Benzhong's side.

Liu Cong commanded the two team members and took out a long, hard thing like a wire from the backpack. Seeing the lens installed in front of him, Chen Ziyang knew that this should be something similar to an endoscope, which could be inserted directly from the hole, and at the same time, the situation inside the hole was fed back with a probe.

"How did you come up with the idea to use that pearl to open this door?" Although the door has not yet opened, Chen Benzhong's thoughts are the same as Chen Ziyang's, he feels that this pearl should be the key to opening the door, so he can't wait to ask Chen Ziyang.

"The reason is actually very simple, that is, because this pearl should have been set in Kangxi's crown before. Although this argument may seem insufficient, it makes a lot of sense.

The dragon vein of the Qing Dynasty should have been built during the Kangxi period, and all the clues we found have come to this conclusion, that is to say, if the dragon vein treasure of the Qing Dynasty is set up with a method to open, it can only be set by Kangxi.

You also know what happened when Pu Yi fled to Da Walnut Town, the pearl inlaid in Kangxi's crown was lost, and Pu Yi's jade seal was lost. If something else is forgivable, the loss of these two things is obviously a bit unbelievable.

Putting these together, coupled with the extra bulge on the gate, all this gave me the idea that the pearl inlaid in Kangxi's crown is the key to unlocking the Dragon Vein Dungeon.

This pearl has been inlaid in Kangxi's crown, it can be said that other people have no way to get it, even if Kangxi is gone, his pearl will be preserved as a national treasure, which ensures that the owner of this pearl can only be the emperor of the Qing Dynasty, and ensures that the opening of the dragon vein is in the hands of the Qing royal family. ”

After listening to Chen Ziyang's explanation, Chen Benzhong's eyes were full of excitement, and he couldn't wait to see what was behind this gate.

"Cong'er, how's the situation on your side?" Chen Benzhong asked a little anxiously.

"Nothing was detected, and the black hole suddenly changed direction after going half a meter deeper, turning diagonally downward. It's pitch black inside, the side walls are very smooth, and the hole is very deep, our probe is already in the end, but we still haven't seen anything else. ”

"Alright, don't look any further, take the probe back, let's open this door." After taking the pearl from Chen Ziyang's hand, Chen Benzhong stepped forward slowly, it seemed that he was going to open the door of the underground palace of the dragon vein treasure of the Great Qing Dynasty with his own hands.

When he put the pearl into the hole, Chen Benzhong's wrinkled hand trembled rapidly, obviously he was very excited.

The size of the "Gollum ......" pearl is closely matched to the diameter of the hole, and although the wind blowing out of the hole is still very strong, it cannot prevent the pearl from entering. The sound of the pearl rolling in the pipe behind the hole came back, and the sound became quieter and quieter, and it was clear that the pearl had rolled deep, far away.

The sound of the "crunching ......" recoiled spring activation came from behind the steel gate, and with the sound of the mechanism activating, the four dragons on the gate seemed to come to life.

The four dragon-shaped reliefs began to move little by little from the tail, and the scales on the dragon's body unfolded little by little, making the length of the four dragons slowly extend, although the distance between the scales was very short every time they moved, but because the scales on the dragon's body were very numerous, these subtle extensions were added together, and the entire dragon head moved forward for a long distance.

"Quack!" The dragon heads of the four dragons touched the circular hole in the center at the same time, and the dragon ball-like thing that had been set aside by Chen Ziyang before was pushed back to its original position by the dragon heads of the four dragons.

Under Liu Cong's pull, Chen Benzhong stayed away from the range in front of the gate, and after a while, the two doors opened slightly, and a wide gap appeared between the two gates.

A gust of wind blew through the crack in the door, and the gust of wind was mixed with a strong musty smell. That is, at the moment when the wind blew, the flame emitted by the burning of the candle made of dog oil hanging on Chen Benzhong's waist suddenly changed color, and instantly changed from bright yellow to dark green.

This proves that the air quality blowing from behind the door is very bad, the carbon dioxide content is very high, and at the same time, the air detector in Liu Cong's hand also emits a didi alarm.

"Put on your gas mask." With Liu Cong's order, the others hurriedly put gas masks on their faces and opened the valve of the oxygen tank at the same time.

"Don't worry, the air here is circulating, although the area of this dungeon is very large, and the quality of the air inside is not very good, but as long as the door is opened, the air will be exchanged, and it won't be long before the air inside can breathe."

It wasn't until the gates opened that the people in the team realized that the two gates were much thicker and heavier than they had imagined, and the thickness of the gates was already more than a meter.

In addition, on the side edge of the gate, you can see a lot of brackets, all of which are made of steel, which looks very precise, and must have involved a lot of mechanisms.

Although everyone did not understand the design of this gate, everyone knew that if they had used violent methods to open this gate, they would not be able to blow it open, and it would also touch other defense mechanisms.

"Hahahaha...... My long-cherished wish for many years is about to come true, Cong'er, be a pioneer! Chen Benzhong's eyes flashed with tears, and his voice trembled because he was too excited, and when he said this, he almost shouted by his neck, and the green tendons on his neck bulged out.

Just as Chen Benzhong expected before, the air inside and outside the gate was constantly exchanged, and after a while, the wind blowing from behind the gate weakened a lot, and the flame of the dog oil candle hanging on Chen Benzhong's waist has not been extinguished, and now the color of the flame is still green, but it is no longer dark green, and the color is much lighter.

After sending two team members to explore the way, the members of the team went to the back of the gate one after another.

Behind the steel gate is a large space, but the area of this space is not very large, under the light of the flashlight, the team found that dozens of meters in front of it is still a section of the city wall, this wall is very similar to the wall next to the gate.

In front of them to the left was a little different, with what looked like a dragon's body carved out of stone sticking out of one wall and burrowing into another.

As soon as he saw this stone sculpture like a dragon's body, Chen Ziyang's heart had a strange feeling, he hurriedly poured mana into his eyes, and after opening the yin and yang eyes, he looked towards this stone carving.

"Dragon Qi! There is a dragon flowing in the stone carving! ”
