Reaching out and taking out five keys of different lengths from his pocket, Qin Feng's expression was also a little nervous, this was the first door product he had seen in the world, so he naturally didn't want it to be destroyed.

Qin Feng glanced back and said with a solemn expression: "Old Miao, you step back a little, if there is anything wrong, climb up immediately." ”

"Master Qin, it's okay, I'll help you with a flashlight while standing here." Miao Liuzhi shook his head and refused to retreat.

"You're fine, I'm fine."

Qin Feng rolled his eyes when he heard this, and said, "Who knows what those people in the organ gate think, if this passage collapses at that time, how can I run if you block it there?" ”

In any case, Qin Feng is now three meters below the ground, and if this corner really collapses, he will have ten lives gone, and he has to give himself a good way out.

"Well, yes, I'd better go up first."

Miao Liuzhi thought about it carefully, what Qin Feng said was also that if there was any accident, with his current reaction ability, he would really become a burden to Qin Feng.

"Well, open it and I'll call you."

Qin Feng nodded, this passage is supported by pillars, even if it collapses, it will take a few seconds, without Miao Liuzhi blocking him, it is enough for Qin Feng to escape.

"Ancestor bless!" After Miao Liuzhi withdrew, Qin Feng folded his hands reverently and bowed to the iron gate in front of him.

To say that Qin Feng was also very curious in his heart, the Five Elements Lock represented the highest level in the Organ Door.

So far, the five-element lock has only appeared in the harem of the Qing court, that is, in the current Forbidden City, but no one could break the five-element lock on the door at the beginning. Everything inside was destroyed.

Taking a deep breath, Qin Feng inserted the first key, which was about fifteen centimeters long, into the keyhole representing the five elements of gold, and when the key was inserted into three-fifths, Qin Feng stopped his hand and twisted it slightly to the left.

Just listen to "Click! There was a soft sound. Suddenly the key sank in a fifth of the way, and turned a full circle to the left, leaving only one key head outside, and at the same time, there was a sound of gears twisting from inside the door.

"It's done!"

Qin Feng showed an excited look on his face, and without hesitation, he inserted the second key into the keyhole representing the five elements of "wood", but this time the direction of Qin Feng's twist was to the right.

Same as the first key. The second key also turned automatically, and the sound of the machinery in the door was clearly audible, and Qin Feng knew that the second level had also been cracked by him.

However, there are still three keys, Qin Feng does not dare to be careless at all, his body is in a state of extreme tension, as long as there is the slightest mistake, he will exit this secret passage and return to the ground as quickly as possible.

Thankfully. The third and fourth keys were unmistakable. It fits smoothly with a keyhole.

However, without inserting a key, Qin Feng seemed to have spent a lot of strength, in this cold winter wax moon, Qin Feng's forehead was already covered with beads of sweat, and his eyes showed a tired look.

"Zuihou is a handful, Master Zu blesses you!"

Holding a key that is twenty centimeters long. Qin Feng said a silent sentence in his heart, and after taking a deep breath, he gritted his teeth and inserted the key into the lock hole.

"Left three, right four, don't drop the chain, open it for me!"

After this key is inserted. Qin Feng first twisted three times to the left, then four times to the right, Zuihou pressed the key inside, and his body quickly stepped back.

Qin Feng knew that if he made a mistake in this move, then all the previous efforts would be wasted, and at this time, his right foot was on a stone step, and as long as there was a slight mistake, he would immediately climb out of the secret passage.

"Click...... Click......" The sound of mechanical rotation was so harsh in the depths of the earth,

The key that was safely pressed into the lock hole by Qin Feng was like a center, driving the other four keys to rotate at the same time, and the "click" sound was endless.

"It's done!" Hearing the sound of the machine turning, Qin Feng breathed a sigh of relief, and couldn't help but admire the wisdom of the predecessors of the organ gate in his heart.

In the case that there was almost no industry more than a hundred years ago, they were able to build such a delicate mechanism, and they didn't know how much manpower and energy it would take, in Qin Feng's opinion, it was almost unimaginable.

"Click...... Click......"

After the key automatically rotated for almost thirty seconds, a soft sound came into Qin Feng's ears, and the bulky big iron door slowly opened from the inside out.

"Old Miao, come down!" Qin Feng raised his head and shouted, and as soon as the words fell, Miao Liuzhi went down to the bottom of the pit with an agile movement that was extremely inconsistent with his age.

"Qin ...... Qin Ye, it's really ...... Really opened? ”

As soon as Miao Liuzhi asked, he closed his mouth tightly, because the iron door in front of him had been opened for most of the time, and a turbid air blew out of the space inside the door.

"Old Miao, hold your breath ......"

Qin Feng's throat moved, but he didn't open his mouth, these turbidities may not be poisonous, but the air in the space has been sealed for a hundred years, maybe there are some germs.

Just like the curse of the so-called pharaoh back then, scientists from various countries who entered the pyramid died one after another, in fact, because they breathed the air in the pyramid and were invaded by the germs that breathed into the body.

Miao Liuzhi had also been to the tomb back then, and without Qin Feng's size, he covered his mouth and nose with his sleeves, revealing only a pair of eyes staring at the open iron door.

The iron door opened very slowly, and it took more than three minutes before it was completely opened, and the four oil lamps at the bend emitted a bright light, closing the secret room for a hundred years, and presenting it in front of Qin Feng and Miao Liuzhi.

"Master Qin, let's go in, it should be fine!" Miao Liuzhi put down the hand covering his mouth and nose, and there was an excited look in his eyes.

"Lao Miao, don't worry......" Qin Feng grabbed him and said, "You follow my footprints, don't be wrong!" ”

"What? And the organs? Miao Liuzhi was stunned when he heard this, and said: "The one who can open this secret room must be the descendant of Lao Ma, he might as well be on guard, right?" ”

Qin Feng shook his head and said, "Be careful to sail the 10,000-year-old boat, old Miao, don't get along with yourself." ”

Reaching out and taking the flashlight in Miao Liuzhi's hand, Qin Feng walked in front, in fact, there were four lights at the bend, and the outline of this secret room could already be vaguely seen.

The chamber is not very large, only two meters in height, four meters in length and four meters in width, in the shape of a square, a total of less than twenty square meters, surrounded by masonry walls on all sides.

Along the circle of the secret room, there are eight lacquered mahogany boxes about 50 centimeters high, two boxes are placed in each direction, and in the middle of the secret room, there is also a sand table used for marching and fighting.

"Lao Miao, don't go wrong!"

After Qin Feng stepped into the secret room, he took two small steps forward, less than a meter, and then suddenly walked three steps in a row, these three steps were relatively large, and after stepping out, he had already reached the edge of the wall.

"Master Qin, what are you doing here?"

Seeing Qin Feng's actions, Miao Liuzhi couldn't help but be stunned for a moment, but due to the thick layer of dust on the ground, Qin Feng's shoe prints were not difficult to identify, and Miao Liuzhi followed Qin Feng to his back.

"It's all on the ground, Master Qin, it won't be wrong." Miao Liuzhi stomped the ground, and his eyes looked around.

There is nothing else in this secret room except for the box and the sand table, the box is covered, and there is no way to know what is inside, Miao Liuzhi's eyes are naturally placed on the sand table.

"It's true on the ground, but it's better to be careful."

The route that Qin Feng took was the secret of the organ gate, as long as it was a mechanism set up by the organ gate, it would be safe to follow this line.

"Hey, strange, what is Ma Xinyi doing here with a marching sand table?"

At this time, Qin Feng's gaze also fell on the sand table, and he said with some puzzlement: "Even if Ma Xinyi has led soldiers to fight, there is no need to make a sand table here, right?" ”

The sand table in front of me is about one meter long and about 60 centimeters wide, with mountains and rivers on it, just like an ancient landscape painting.

It's just that there are small colored flags in several places, so it looks like a sand table used for marching and fighting in ancient times.

The base of the sand table is built with blue bricks, about one meter high, and the sand table itself is made of clay, surrounded by wooden frames, which is very exquisitely made.

"Qin ...... Qin Ye, this ...... Could this be the treasure map of the Taiping Heavenly Kingdom? ”

Staring at the sand table tightly, Miao Liuzhi swallowed a mouthful of spit, and stammered: "Although Ma Xinyi is a literati and has been a jinshi, he is also a military talent, and he is very good at marching and fighting, but this ...... There's definitely something strange about this sandbox. ”

"Lao Miao, what do you see?" Qin Feng looked at the sand table and said, "You have been to a little more places, look at where the terrain is?" ”

As he spoke, Qin Feng's eyes were not idle, and he kept every prescription on the sand table firmly in his mind, if it weren't for the lack of paper and pen in his hand, Qin Feng would even want to draw it.

"It looks a little familiar, these should be two mountains."

Miao Liuzhi racked his brains to compare the sand table in front of him with the terrain in his mind, and said hesitantly: "It's a bit like the terrain of Jinling, Qin Ye, look, these two mountains on the left and one on the right are not like the Purple Mountain and Qixia Mountain in Jinling?" ”

"I've never been to Jinling, and I don't know the map over there." Qin Feng shook his head and said, "However, the Taiping Heavenly Kingdom once built its capital in Jinling, so it may really have something to do with those people." ”

"Master Qin, it's not that maybe, it must be!"

Miao Liuzhi's face was already flushed with excitement at this moment, and he said hurriedly: "At the beginning, the Taiping Heavenly Kingdom built the capital of Jinling, known as Tianjing, and Ma Xinyi left such a sand table in this secret room, do you say that there can be other meanings?" ”

In addition to being excited, Miao Liuzhi had long forgotten Qin Feng's entrustment, and raised his feet like a sand table, his shili was not as good as Qin Feng, and only when he got close could he see some subtle places on the sand table clearly. (To be continued......)
