Mu Feng and Xiao Meng grabbed the rope and climbed up. A few people breathed a sigh of relief.

"What the hell was you yelling at just now?" The bearded man said as he looked around.

But at this time, the insect has long since retreated and does not know where to hide. The wind stirred the bushes high and low, and the black back that had just been exposed disappeared without a trace.

Mu Feng patted his body and said, "That must be the natural enemy of the piano worm, fortunately it appeared, otherwise the two of us would definitely die miserably!" ”

Bursts of fragrance still wafted out from the plank road, Chu Tianyi groped for these purple-black woods, and sighed with some emotion, "No wonder those ancestors were able to be neighbors with terrible things like qin insects, it should be these fragrances that restrain its poisonous gas, and the existence of its natural enemies, so that the people of the ancient Xu Kingdom can survive here." ”

The bearded man picked up a piece of broken wood and put it in his bag, "This kind of thing is more useful than the bile duct of the piano worm." Saying that, he took out the small cloth bag with the insect gall from his bag, put it under his nose and sniffed it, and immediately showed a disgusting expression, "I'll go, it's all stinky!" He casually threw the unpacked off the boardwalk.

Mu Feng looked in the direction of the extension of the plank road, "Let's go, let's go along the road of the ancients and see what good things these ancestors have left us." ”

A few people began to move along the plank road, the ancient level of construction was not as perfect as it is today, and there were no railings or other protection measures on the outside of the plank road. Therefore, they take every step very carefully.

Everyone stared intently at their feet, but no one noticed that the gall of the piano that had been thrown under the plank path was hooked by a sharp claw sticking out of the bushes.

The plank road on the stone wall is built according to a zigzag shape, and the plank road is almost one meter wide, theoretically speaking, as long as you concentrate, you can walk on it smoothly. But as Chu Tianyi and the others walked higher and higher along the plank road, looking at the deep canyon under their feet, and listening to the whirring wind in their ears, Chu Tianyi couldn't help but feel dizzy.

There are grooves in the stone wall on the inside of the plank road, and there are very few pieces of wood remaining, which should have been used to place some kind of lighting tools, such as candlesticks or something.

This highly stressful march quickly became physically and mentally exhausting. Chu Tianyi stopped and leaned against the stone wall to relieve himself.

He took a deep breath as he looked around, and suddenly he noticed the large yin charms carved into the stone walls on both sides of the canyon in the direction he came. Because the stone walls are very uneven and the heights are staggered, the yin symbols are presented from various angles.

Looking at Chu Tianyi's location, you will vaguely find that these symbols seem to have some kind of arrangement.

So, as he walked, he turned his head to look at the yin talismans. He found that as he moved, the pattern of these yin symbols also changed. Chu Tianyi was very surprised, and he was also a little distracted, and accidentally bumped into Mu Feng's body in front of him.

Mu Feng was taken aback, and quickly looked back, "Tianyi, what's wrong with you?" ”

"I'm sorry," Chu Tianyi came back to his senses and quickly apologized, "I'm distracted." ”

"It's okay," Mu Feng waved his hand, and then followed Chu Tianyi's gaze just now, "Are you looking at those Yin Talismans?" ”

"Yes," Chu Tianyi nodded, "And I found that as we moved, the arrangement of those Yin talismans also changed. ”

Hearing this, Mu Feng also moved back and forth, and was suddenly surprised, "That's really the case!" As soon as he finished speaking, he suddenly froze. The brow furrowed slightly, as if he had thought of something.

Immediately afterwards, Mu Feng took out the map, "Tianyi, you said that the sentence that Uncle Chu conveyed through the magazine was 'Wolong Playing Pearl, Ear Moon Picture Cave'." ”

Chu Tianyi nodded.

Mu Feng stretched out his hand and gestured on the map, "Look, if the Jinjiang Grand Canyon where we are located is the so-called Wolong, then where does the so-called play bead mean?" ”

After Mu Feng said this, Chu Tianyi finally understood why every time he saw the map, a thought flashed through him, and he immediately pointed to the Changbai Mountain Tianchi marked on the map and said, "It should be here!" ”

"That's right," Mu Feng looked at Chu Tianyi approvingly, "Then the place we are looking for should be between the two, and the specific location or entrance should be the content of the second half of the sentence." ”

"Ear Moon Diagram Cave?" Chu Tianyi felt that this half sentence was even more difficult to understand, almost incomprehensible.

Xiao Meng and the bearded man couldn't understand what Chu Tianyi and Mu Feng were saying, and they looked at them with a little dazed eyes.

Mu Feng nodded, "This sentence doesn't make sense, but that's the problem." Don't forget, Uncle Chu uses ready-made words in magazines to convey information. It is possible that due to the rush of time, or by coincidence, he did not find the word he wanted to use at that time, so there may be a way to replace it. ”

Chu Tianyi drew a picture with his fingers in the palm of his hand, and suddenly raised his head in surprise, "I understand, it may be that two words are combined into one word, such as the ear moon here, in fact, one ear plus a month, that is a yin word." Then this sentence is the Yin Tu Cave. ”

Mu Feng looked up at it, "Uncle Chu's words should be marking a place, this place is between the Wolong and the pearls, and from the map, it is the eyes of this canyon in the direction of Tianchi in Changbai Mountain, and this section belongs to the underground canyon, it is not on the surface." And the so-called cave in the second sentence should be the meaning of the cave, I think what he refers to is the entrance to the underground canyon, and the key to finding this entrance is the Yin map. ”

Mu Feng's analysis can be said to be very reasonable, and Chu Tianyi also nodded frequently, "But where is this so-called Yin Diagram?" ”

"I don't know the specifics, but," Mu Feng said, pointing to the large yin talismans carved into the cliffs, "but I think it must have something to do with those." ”

Chu Tianyi observed carefully for a while, but he couldn't see any doorway.

Xiao Meng and the bearded man were even more confused, and couldn't help asking, "Two big brothers, what are you talking about?" ”

Mu Feng smiled, "This is a very professional academic discussion, you don't understand it, but you will know it when the time comes." ”

Several people continued to move along the plank road, and Chu Tianyi and Mu Feng closely watched the changes in the arrangement of those yin talismans in the distance.

After walking for a while, Mu Feng suddenly exclaimed, "I understand!" The so-called yin diagram must not be a single symbol, but must have a complete pattern. Therefore, the yin charms on the cliffs on both sides of the valley floor over there must be connected together. ”

"Together?" Xiao Meng said in surprise, "How is this possible! ”

"Of course you can," the corners of Mu Feng's mouth rose slightly, "just change the angle." I think this location should be in the ......" he said, looking up and looking up, and then pointed to a plank road in the southeast of it, which was almost the end of the plank road, Mu Feng said with some excitement, "It should be near there." ”

Mu Feng trotted all the way to that position quickly, the plank road was trampled by him, and the frightened Chu Tianyi, Xiao Meng and Da Beard The legs of the three people were a little weak, Xiao Meng shouted at Mu Feng, "Brother Feng, you light, the plank road is about to be trampled by you." ”

"Shut up!" The bearded man scolded, "Don't talk nonsense, crow's mouth!" ”

Chu Tianyi leaned sideways against the stone wall, and when he turned his head, he suddenly saw a big black shadow in the bushes below. And when he looked at it again, the shadow was nowhere to be found.

Just when the three of them stopped, Mu Feng had already reached the position he predicted, he raised a hand and made a "pergola" on his forehead, looking in the direction of the Yin Fu arrangement. Suddenly, he shouted excitedly, "Haha!! Got it!! ”
