After leaving Di Cemetery, we returned to the temporary accommodation arranged by the Zhang family. We thought about the clues of Di Cemetery with questions, combined with the road map of Zhangjiazu, the more we thought about it, the stranger it became. Di Gong lived in the Tang Dynasty, and Zhang's ancestor was in the Western Jin Dynasty, the difference between the two is hundreds of years, what is the connection? Lao Jiang: How did they know that they could find clues in Di Cemetery? As explained above, in addition to this text, there is also a small picture of a person holding a sword to slash at a big snake, obviously cutting the white snake for Liu Bang, does it indicate that the place to go below is Mangdan? There are a lot of things, no matter what, let's go to Mangdang to investigate first, hoping to get something.

Mangdang Mountain, known as Dangshan in ancient times, is famous for the Han Gaozu Liu Bang's snake slashing uprising. Zhang Shifan and I still pretended to be tourists and came to Mangdang Mountain, and after making a little preparation for the temporary accommodation arranged by the Zhang family, we began a new exploration. I said to Zhang Shifan: "Xiao Fan, according to the picture on the Di Cemetery, the person who beheaded the white snake should be Liu Bang, and according to historical records, the location of the white snake should be Mangdang Mountain. But this place is so big, I don't know where to look? Zhang Shifan said: "Brother Long is right, hey, by the way, let's take a look at the picture on Zhang Jiazu and see what can be compared." After speaking, he took out the road map copied from Zhang Xiaofeng, and Zhang Xiaofeng said that it was just a road map, without any instructions, and I didn't look carefully at the time, so I hurried to Luoyang. Now look at this picture, the whole picture is about the size of A3 paper, the front of the picture draws a mountain, or a mountain peak, the whole mountain is painted red, the belly of the mountain is painted like a crown hat worn by ancient people, and a Tai Chi pattern is also drawn on the side. On the reverse side is a road map, along which there are three locations, respectively written with great wisdom, great courage, and great power, and marked with seven, thirteen, fourteen, three numbers. Finally, there is another paragraph: Those who can come here and solve this mystery must be wise, courageous, and powerful people, and only then can they be entrusted with the burden of the world.

I looked at the picture a few times, but I still couldn't figure out what it had to do with Mangdang Mountain, so I panicked, so I went outside the house to breathe. At this time, a pair of travelers passed by me, and one of them said, "Let's go to Chidi Peak tomorrow." Another person said, "Well, I heard that there was a strange noise there a few days ago, and it disappeared all of a sudden, and many people heard it, and there might be something interesting." "The speaker was unintentional, the listener was intentional, I immediately returned to the house, took out the Mangdang Mountain tourism map, and then compared the peaks on the road map, sure enough, it was the Red Emperor Peak, it really didn't take any effort to get it. I happily called Shifan and told her about my discovery, and she was also excited. I said: "I heard from those two travelers, there was a strange noise in the Red Emperor Peak, I think it should be caused by Lao Jiang and them finding the entrance and triggering some organ news." Without further ado, let's get ready and head off tonight! "Okay, I'll go get ready!"

I unfolded my treasure bag and checked the items again. Old friend, we're going to go together again, I said to myself. A short steel knife, a disassembleable laser crossbow, a pack of treasure hunting elixirs (healing and detoxification), flying ropes, waterproof flashlights and glow sticks, some compressed food, some waterproof wrapping materials, and a record book made of waterproof and antiseptic materials. It is worth mentioning the short-handled stainless steel umbrella, which was obtained from a captain who touched the gold, and was very useful for the news of the defense agency. I was carrying the treasure bag when I saw Zhang Shifan walking towards my room and handing me a silver-white dress. "Brother Long, this is our Zhang family's special silver silk soft coat, which can be partially anti-knife and gun mechanism, you can wear it inside." Sure enough, it's a treasure hunt, and there are really unusual things. "Then you're welcome, thank you!"

We took advantage of the night, evaded the mountain patrols, and went straight to the Red Emperor Peak. According to the road map, the destination should be on the side of the mountain, and if we can't climb it normally, we have to go to the top of the mountain first and slide down to the side of the mountain with a hanging rope. But I don't know the specific location, so I had to divide the labor between the two, I went down to look for it, and Zhang Shifan first watched the sentry on the top of the mountain to prevent emergencies. I just roughly observed the position at the foot of the mountain, it should be a little lower in the middle of the Red Emperor Peak, where it looks like it has been deliberately disguised, of course, this is a unique method that our treasure hunters have mastered, and ordinary people can't see it. I slid from the rope to the approximate position, fixed my figure, turned on the flashlight and slowly groped for it. Suddenly, I noticed something unusual about a rock pine, I opened it with my hand, and a Tai Chi figure stood out in front of me. I used the intercom to tell Zhang Shifan about the discovery, and asked her to wait, and I tried to see what kind of mechanism this was. I tried spinning left and right, but pressing down had no effect. Tai Chi Yin and Yang, I had an idea, and at the same time pressed the Yin and Yang fish eye, only to see a slight vibration, there appeared a round door that only allowed one person to enter, after entering is a spiraling downward channel, there are torches in the passage, it seems that someone has been here recently, it should be Lao Jiang them.

I waited for Zhang Shifan in the passage for a while, and she also entered smoothly to meet me. As we walked out of the passage, an open space appeared in front of us, and four dragon pillars showed their majesty. The moment we stepped into the floor of the room, we only heard a soft sound behind us, and the round door that we had just entered closed again, and it seemed that the person who designed this underground palace had to come to complete the test before he could get out, otherwise there was only a dead end. Zhang Shifan and I used a flashlight to look around, and it was all made of extremely hard blue bricks, and after making sure that there should be no mechanism on the ground, we walked straight ahead. I saw that there was a wall in front of me, and the wall was cut into squares, each square was carved with a word, and there was a square door that had been opened under the wall. The two of us looked at each other for a moment, and understood that this puzzle mechanism should be solved by Lao Jiang and them first. I saw that the words on the wall were combined with a commandment: If you can enter this door, those who succeed will live, and those who fail will die.

Without further ado, we entered the square door under the wall, which was still a downward spiraling passage, and at the end there was an empty space. I saw that the floor was paved with black marble, carved with white dots, and a big "seven" was written on the opposite wall, and there was still an open square door below. I looked closely, the ground was carved with dots, and it should not be difficult to guess that it was the Big Dipper by comparing the word "seven" on the wall, and as long as I pressed the point where the seven stars were, I could pass through this place. I turned the flashlight into a state of strong light, shone it on the ground, and measured the distance, no, according to this method, I couldn't go to the other side, I could only go to two-thirds of the way, which was really strange. At this time, Zhang Shifan said softly: "This is like the Big Dipper Seven Star Chart, but it is a little wrong, if you want to go to the opposite side, you have to step on at least two points." When I heard this, I was immediately shocked into a cold sweat, and at the same time, I admired Lao Jiang even more. It turns out that this is the nine stars of the Big Dipper recorded in ancient books, not the seven stars, "seven appear and two hidden", that is, the seven stars can be seen, and the other two are hidden. I will find that when I heard it with Zhang Shifan, she was also surprised, and it seems that she didn't expect this layer either. I walked forward on the established dot, and the front was smooth, and when I reached the eighth point, my foot was half a minute to the left, and I heard a slight sound of the spring starting, and I suddenly felt bad, I did not expect this mechanism to be so exquisitely designed. I instinctively moved my foot back half a minute, but I saw a long axe fall at my foot, and if I hesitated for half a minute, one of my feet would be useless. I shouted to Zhang Shifan: "Xiaofan, be careful to settle down, you can't make a mistake by half a point, otherwise the mechanism will be triggered." Xiao Fan also saw the danger just now, nodded and agreed, and passed here smoothly.

We quickly entered the square door, only to see the space made of white stone in front of us, opposite to two doors, and on the wall directly above was a large "thirteen". On the side of one of the doors was a person leaning against him, it was Lao Jiang, who was covered in blood and unconscious. I was in a hurry, ran forward, and shook him desperately, "Lao Jiang, Lao Jiang, wake up!" Lao Jiang didn't react, my heart sank to the bottom, Zhang Shifan saw Lao Jiang covered in blood, and quietly turned his head. At this time, a somewhat tired voice sounded, "Don't shake it, if you shake the old bones again, they will fall apart, but your kid is still here!" "I'll go, old man, you're not dead."

What dangerous thing did Lao Jiang encounter? Can Long Jianfeng succeed? If you want to know what happens next, and see the next chapter breakdown.
