The book continues above. Shen Yifan saw the knife in the black shadow's hand and already knew that this person's origin should be not small, and he may also be a member of the gold fighting line, because it is rumored that the 'mourning department' also has a function of helping Li Shimin rob the tomb to raise military salaries, so the weapons of the mourning department are still tools for tomb robbing. The knife in the hand of the black shadow is also called the 'golden ruler' is the officer saber of the post of the lieutenant of the mourning department, the blood groove of this knife has a lot of barbs that are difficult to see with the naked eye, in fact, the effect is similar to the Luoyang shovel used now, plus the scabbard of this knife can be connected to the handle of the knife to become a long knife, so the length of the bottom is lengthened. Li Shimin's funeral weapons are many kinds, and the position and rank of this person in the army can be seen on the weapons and armor, such as the 'golden ruler' used by the lieutenant is a good example, as long as you see the golden ruler, this person must be a lieutenant in the army. The soldier's saber is shorter than the 'golden ruler', but the blade is wide, the front end is very sharp, and it can be used as a shovel, and there is a ghost head decoration on the hilt, in fact, this decoration may be used as a hammer, plus the soldier is also equipped with an iron spear, this spear is very strange, the spear body is actually hollow, I don't know what to use.

A few years ago, I saw and found an ancient tomb in Xianyang, which included a set of soldiers' weapons, armor and burial horses of the Tang Dynasty funeral department, experts have studied this strange spear and have not explained it, and then can only guess that it may be a tool used to bleed, and why it is necessary to use such a thing to bleed is unknown.

Li Shimin's 'black-armored cavalry' has a lot of mysterious colors, and we will not show it here.

Shen Yifan saw the ancient knife in this person's hand and guessed that he was either a descendant of the mourning department or also used a golden ruler to get promoted and make a fortune, and secretly thought in his heart: "Could it be that this person entered the Great Beidou to do the trick of touching the gold inverted bucket?" Wrong. This person should know what happened to me before when I asked me to light the lamp, but if so, it would not be easy for this person to come from. Thinking of this, he asked, "Who are you?" ”

The black shadow seemed to be able to penetrate Shen Yifan's heart and secretly smiled: "You don't need to know who I am, and I won't tell you about the past." I'm just a messenger. ”

"Messenger?" Shen Yifan had some regrets.

The Black Shadow sneered again, "If you're going to cross the woods ahead, I want to tell you that you can leave now." If you leave now, there may still be a glimmer of hope for life. ”

"What do you mean?" Shen Yifan asked.

The shadow man had vanished, and just then another stone shot out of the thick darkness, wrapped in a cloth. Shen Yifan unfolded the piece of cloth and saw that it was a hand-drawn map, with three lines of words underneath. The first line reads: "This is the line out of the woods." The second line reads: "You must cross the woods before one o'clock in the morning, and immediately go up the high slopes out of the woods." The third line reads: "Don't tell anyone about what you've seen me." Remember! It's anyone. ”

Shen Yifan walked towards the camp while looking at the map, when he arrived at the camp, he had already read the map well, all the way he hugged a lot of branches, sandwiched the map inside, and put the branches into the fire, a few people who had just woken up looked at Shen Yifan and thought that he was going to collect firewood, but he didn't think much about it.

Shen Yifan was still reminiscing about what the black shadow said, staring blankly at the fire. Suddenly, he seemed to have figured out something, and quickly stood up and said to a team member sitting opposite: "Wake everyone up immediately, let's go immediately." The team members were a little puzzled, but Jin Jianyu once said that Shen Yifan's words, they had to obey everything unconditionally, and they could only blow the whistle, which was the same as the emergency assembly number in the army, indicating that there was a very urgent matter.

As soon as the whistle blew and everyone woke up very quickly, Jack asked, "What happened?" ”

"Let's go right away. Otherwise, it will be too late. Shen Yifan said.

Jin Zhuyu was a little puzzled and asked, "Too late?" What's too late? ”

Shen Yifan put on his backpack and said, "It's too late to escape." AS HE SPOKE, HE LIFTED ARC AND SAID, "I'LL LEAD THE WAY." I'll explain it to you on the way. ”

Everyone was very shocked by Shen Yifan's words, feeling that he was not joking, but what danger would happen to them and make them lose their lives? I all felt that Shen Yifan might be a little overwhelmed.

Shen Yifan didn't say anything, everyone put on gas masks and followed Shen Yifan all the way through the woods, and came to the open space where Shen Yifan and Sanniu stayed in the morning, the woods at night were really full of yellow fog, and it was very thick, everyone had to gently peel off the fog in front of them with their hands to see the back of the person in front of them.

Shen Yifan flicked the fog in front of him with both hands, repeating every detail on the map in his mind, according to the map drawing, when they left the clearing in the middle of the woods, they should go in the opposite direction of the swamp, saw a locust tree in it, and then turned right. When they came to the edge of the swamp, Shen Yifan was stunned when he saw the swamp, because he walked in front, and when he peeled off the yellow mist in front of him, he found that the toad that looked like the size of a mountain bag was not one, but two were lying on the swamp, greedily sucking the yellow mist in the woods, the big toad could feel an obvious air flow vortex as soon as he exhaled, and the yellow mist flow also moved. The two toads were almost identical, but one was even larger, like a small mountain, lying there as if it were four or five meters tall.

Shen Yifan immediately stopped and made a silent gesture, and then slowly walked along the edge of the swamp. Fortunately, the two big toads didn't find them, and everyone seemed to see the two big toads so frightened that they didn't even dare to make a sound. Coming to the locust tree drawn on the map, Shen Yifan looked to the right and seemed to hesitate, because the woods on the left seemed to have a road, and the woods on the right were more dense and deep, and the yellow sulfur mist inside was even denser, and he almost couldn't see his fingers. Shen Yifan was a little puzzled, but now he can only go to the end, he exhaled his breath and calmed his emotions and walked towards the dense woods, according to the map that this forest has to turn right every time it reaches a locust tree, and every time the woods turn right are extremely dense, and the team is getting deeper and deeper in the woods.

After walking for more than half an hour, Shen Yifan saw a sign on the map, a wooden stake that was exactly the same as the swamp, according to the indication on the map, the area behind the wooden stake was a forbidden place for this wood, and once you entered, your life would be in danger. Shen Yifan remembered in his mind that the wooden stakes like this on the map showed that there were four places, distributed in the southeast, northwest, and four directions. Such a stake was also seen in the swamp, and later giant mosquitoes and giant toads were seen. And what will be behind this stake in front of him?

There are not many words, Shen Yifan saw the wooden stake according to the indication on the map, and then went to the left hand side, half of the kung fu heard the huge sound of flowing water, the sulfur fog flow was more intense, when everyone followed the sound of flowing water to a waterfall pool, what they saw was a lonely mountain about five stories high, this lonely mountain is very special, because the mountain is yellow all over, there is not a single plant, and a column of waterfall pours down from the top of the mountain, the water of the waterfall is also yellow, the mountains are surrounded by thick yellow mist, the waterhole is also yellow, and more fog slowly rises in the waterhole. Apparently the sulphur mist in the woods comes from here, but where does the sulphurous water come from?

According to the map, when they came to this sulfur waterfall waterhole, they could see that there was a passage close to the right of the waterfall that could only be entered by one person, and Shen Yifan quickly found this passage according to the guidance of the map. It was more of a passage than a narrow crack between the mountains, and everyone had to turn sideways to barely move in, and when they passed through the narrow crack that day, they found that there was an open space in front of them, and not far from them they could already see the entrance to the Absolute Horse Ditch in the night fog. To the left of their people was a mountain beam, and the highest point above it was not even higher than the mountain that poured into the waterfall, and it should be the highest place here. Shen Yifan immediately thought of the prompt on the map that they would camp on the highest hillside when they left the woods, which might be what they were referring to.

Shen Yifan pointed to the high slope and signaled where to go, at this time, Fang Zi showed Shen Yifan the airflow meter, Shen Yifan nodded, and decisively took off the gas mask, this move surprised everyone a lot, but looking at the sulfur fog flow in front of him, it seems that there should be no danger. Everyone took the mask and took a deep breath, feeling that the air here seemed to be acceptable, so they followed Shen Yifan towards the high slope.

It was almost twelve o'clock, and not long after they had set up camp on the high slope, they heard a very dull thunder, which seemed to come closer and closer, and sounded like a million horses galloping.

Jin Zhuyu asked, "What sound?" ”

Everyone also looked at the place where the sound came from, and it seemed that it was coming from Juemagou, but there was no movement in front of them.

Murong Wan'er was a little scared and said, "Could it be some kind of big monster?" ”

At this time, the captain of the Flying Eagle Squad volunteered to lead the team down to investigate, and Shen Yifan strongly objected and said: "The situation is unknown now, I think it is safe here." ”

Several people ignored Shen Yifan's words, and walked towards the bottom of the hillside by themselves. Just then the rumbling noise was getting closer and closer, and it felt like it was coming to them soon.

Shen Yifan said to the gold inlaid jade: "Quick! Let them come up. "Before the word 'come' was finished, I saw a column of water erupt from the Juema Ditch, and then a huge wave would gush out of the Juema Ditch.

Everyone could feel a huge heat wave rushing towards them, and suddenly it felt like they were in a room full of heating, the huge wave with yellow was amazingly fast, and the people of the Flying Eagle Team had already been swept by the huge wave before they could react, and the huge wave converged on the mountain beam under Shen Yifan's feet, and the speed slowly slowed down.

You can see that at their feet, less than a meter high, a river like a yellow ribbon slowly flows down the hill in front of them, and they can see the reason for the formation of the waterfall. Ah Bing looked at the yellow water, there were still blisters on it, and she was a little curious, and suddenly a white bone floated in front of her, even if she was bold, she was frightened, and she lost three souls and seven spirits. One stumbled ahead and fell, but fortunately was stopped by the expert.

The motor hooked the white bone with a mountaineering pickaxe and lifted it up, just like fishing for a bone from a hot soup pot, and there was actually a smell of meat coming to the nose, at this time everyone already knew what was going on with this white bone, and they couldn't help but retreat back.

"The water is at least 100 degrees, and at this rate, the low-lying part of the forest is now completely submerged," the expert said. Fortunately, we left early and chose to camp here, otherwise it would have been a pot of stew. ”

Shen Yifan said: "I estimate that this water will be absorbed by the swamp when it reaches the swamp of the woods, so Sanniu and I saw the swamp full of animal corpses in the morning, and it is possible that this is how it came from." ”

Maybe you can't understand it. In fact, this principle is very simple and can be seen by each of us, which is the principle of draining water from the pool at home. When the sulphur water gushes out of the ground and comes along the Juma ditch, most of it goes directly to the woods and marshes and then back to the ground, and some of the water on the mountain beam merges into the waterfall pool. Because the swamp acts like a floor drain, the macro suction force brings the things in the water to the swamp, and the swamp becomes a filtering net layer by layer. That's it, Shen Yifan and Sanniu saw that the swamp was covered with white bones and corpses.

At this time, Jack and the others really admired Shen Yifan to the extent of worship, it wasn't for Shen Yifan's excessive nervousness, they might have been cooked in the swamp now. Now it can also explain what the huge thermal energy they saw on the drone instrument is the sulfur water they just saw.

Shen Yifan speculated that the Great Beidou should have an unstable underground active volcano, this volcano should be very deep underground, there may be huge water resources on it, the crater may have an irregular time every day, the eruption impact and volcanic magma with a large amount of water spurted out of the ground and surging to the woods, it is possible that such a movement has been maintained for thousands of years or longer.

Fang Zi said on the side: "Then let's cross the Juma Ditch as soon as possible, who knows when the next sulfur tide will come?" ”

Shen Yifan also nodded with the same feeling, and at this time Murong Wan'er said: "I remember that the people in the family who came back from the Great Beidou said that there is a natural very huge hot spring pool on the side of Juma Gou, and the water in it is very comfortable and has the effect of medical treatment. However, I have looked here many times and it seems that I have not found such a hot spring pool. ”

Shen Yifan looked through the binoculars to see that there was indeed no hot spring pool near Jumagou as Murong Wan'er said, but he seemed to see a low-lying area, which looked like a round giant bowl embedded in the open ground near Jumagou from a distance, and on the edge of the low-lying were the countless uplifted hills seen in the drone image, large and small, densely packed like a big bag growing on the surface.

Shen Yifan thought for a moment and said, "There should be a resurgence." Time won't be fast. We're waiting. After saying this, I didn't wait for a while, and I saw that the water of the yellow river under the mountain beam was actually retreating, and with a crystal clear river in the woods, the water slowly flowed out, and there were two colors of water, one yellow and one clear, but they did not blend, but slowly went in the direction of Juemagou. The clear water quickly forced the sulphur water back to disappear, and then the mountain beam turned directly into a clear river.

The power of nature is terrifying and magical, and the scene that happened in front of Shen Yifan and others made everyone stunned, but at this time, everyone can be sure that there should be no problem now, and it is time to set off for Juemagou.

On this night, they saw a terrible scene in the Great Big Dipper Mountain, the huge waves of sulfur water took the lives of the entire Flying Eagle Squad members in an instant, what else would they encounter next? The weirdness and mystery along the way made Shen Yifan's heart full of apprehension.

And Shen Yifan still has a huge question mark in his heart - that is, who is the black shadow? Why did he want to help Shen Yifan?
