Seeing off the onlookers during the day, the two of them carefully inspected the mysterious house again, inside and out.

Sure enough, as Xiang Zixi guessed, the layout of this house is full of weirdness. Xiang Zixi walked through the winding labyrinthine steps again, judged an approximate distance, and then calculated that the specific location of the underground secret room had extended beyond a mountain bag!

When Xiang Zixi realized this, he couldn't help but admire again and again, and even called it a ghostly building.

Ji Yan looked thoughtfully at Xiang Zixi writing and painting on the ground with a straw stick, frowned lightly and said: "It stands to reason that a craftsman with such exquisite skills is absolutely impossible to be an unknown person, so his disappearance or disappearance should cause a great reaction!" It can't just disappear like that! ”

Xiang Zi Xi nodded approvingly, and said, "Yes, if you can build such a sophisticated and complex basement, even if you are not a god-level craftsman, it should be a great demon level, right?" I've always had a question, no matter how good his skills are, but his skills are not as good as physical strength, how did he hollow out that underground? You know, this is an extremely complex and huge earthwork, without the help of machinery, how did he and a woman do it? This is very puzzling! ”

Ji Yan raised his eyebrows: "If it's not something that one or two people can do, then there must be a group of people who are doing their backup!" There are no flukes in this world! ”

Xiang Zixi's eyes lit up and blurted out: "Are you saying that these two people are just a façade on the surface, and there are actually other people who actually do it?" But such a big project has to be carried out under the noses of the villagers, and it is necessary to hide the figure. How is this possible? It's completely impossible! ”

Ji Yan smiled uninhibitedly: "Won't we actually go and see it?" ”

Ji Yan stretched out his hand to Zi Xi: "Go, didn't you already judge that those small holes were ventilated and convected last night?" So you think, where in this mountain is the wind convection is the strongest? ”

Xiang Zixi suddenly understood, excitedly put his palm in Ji Yan's hand, stood up with his strength, and ran towards a mountain bag not far from this house.

There are mountains all around here, and the mountains are connected to the mountains, but if you can form an extremely strong air convection, you must have sufficient geographical conditions, a narrow passage between two towering mountain passes, and the convection of air is easy to form on one side of the mountain when it is cold and hot on the other side, or other possibilities that are strong enough to form air convection, but in addition to this topographic condition, there must be a mountain spring with abundant water.

Where these two conditions are met at the same time, perhaps the secret lies.

(Khan, I found out that I had given back everything I had learned in school to my teacher.) Is this how the wind is formed? Forgot, Khan. ）

Xiang Zixi climbed to the top of the mountain and looked down, and sure enough, there was a turbulent river at his feet.

Xiang Zixi pointed to the river water, and said excitedly to Ji Yan: "Take me down!" ”

Ji Yan didn't hesitate for a minute, one hand firmly hugged Xiang Zixi's waist, and with a slight touch of his foot, he jumped down down. In the process of falling, Ji Yan's other hand kept borrowing force to prevent the speed of landing too fast and uncontrollable.

Hmm———— Ji Yan hugged Xiang Zixi, lightly touched the water, and jumped onto the riverbank!

Xiang Zixi got down from Ji Yan's arms, squatted on the ground all of a sudden, looked in the direction of the water, and immediately nodded and said, "I see!" This geographical form is indeed a rare and unique natural wind field. ”

Ji Yan looked at Xiang Zixi in confusion, pointed to the towering mountains and the turbulent river in front of him, and slowly explained: "You see, this side of the mountain is a highland, while the other side of the mountain is a low-lying place, and the climate is relatively humid, and the river water flows in the direction of that village from high to low. Because of the convection of the air, it will bring abundant rainfall to the place below, and it will naturally bring strong winds, but because of the barrier of the mountains, when the strong winds pass through this mountain pass, they will be blocked by the mountains near here, and after the diversion, these winds will also blow to other places, unless it is a great storm, it will not affect the mountain villages below. ”

And such a strong mountain wind, when it blew the wind outlet they dug up, it was just when the momentum weakened, but there was still a certain amount of vitality, so it slowly blew into the stone chamber along the wind outlet. And this fast-flowing river has so much water that it is absolutely no problem to draw a tributary from the side! Abundant fresh water also ensures the environment of the basement and the guarantee of human habitation! Xiang Zixi said lightly: "Now, as long as we find the excavated tuyere and water source tributary, then we can basically judge the basic situation of this stone chamber." ”

"The ancestors of the inhabitants of this village were also very discerning and chose the most suitable place to live to build the village." Xiang Zixi sighed lightly; "The person who established the village head, even if he is not a person of great wisdom, must be a person with rich life experience! And I know the right time and place, even astronomy, geography and ecology! ”

Ji Yan hugged his arms and looked at Xiang Zixi thoughtfully: "So, can you tell me, how do you know this?" You are obviously just the daughter of a small landowner in the countryside, or a timid and cowardly girl, how do you know this? Xiang Xiang, don't you think it's a little surprising that you are smart? ”

Xiang Zi Xi smiled heroically, his eyes were full of wildness, and he laughed and said, "That's because I was born as an oracle!" Ji Yan, since I can transform from a cowardly, cowardly, fat, short and ugly girl to a handsome woman who is bold, wild, confident, and pungent, why can't I know a lot of other things that you don't know when the oracle comes? Or, do you still want to say, I'm not sorry for Zixi? ”

Ji Yan scratched the top of his head, with an incomprehensible expression: "You are indeed you, that's right, Jin Haoxuan has always been with you, if you are dropped, it is impossible for him not to find out!" But why is it so different from the front and back? Especially some of the things you say and do are simply incredible. Fortunately, Jin Haoxuan and I are not ordinary people, otherwise it would be strange if you were not immersed in the pig cage by others! ”

"Think of me as a youkai?" The corners of Xiang Zixi's mouth curled slightly: "Then." Do you think I'm a youkai? ”

"Hahahaha————" Ji Yan suddenly became arrogant, slapped his chest, and shouted wildly: "Don't say whether you are a goblin or not, even if you are a ghost and a god of death, so what?" What I Ji Yan likes is you now, even if you become a man-eating monster, I still appreciate it! ”

Listening to Ji Yan's alternative confession, Xiang Zixi suddenly felt warm in his heart.

Ji Yan smiled: "Let's go, let's go and find out, if there is the magical tuyere and tributaries you said!" ”

Xiang Zixi smiled lightly, it feels good to have a friend who trusts him unconditionally!

Xiang Zixi re-stood beside Ji Yan, and after confidently looking at the terrain, he said in a low voice: "The location of the village is over there, so this tuyere must also exist on the side of the river!" As long as we walk slowly along the river, maybe we can find out? ”

Ji Yan didn't talk nonsense, and took Xiang Zixi to float on the wide river, and fell to the other side of the river. Xiang Zixi looked down and saw that Ji Yan's shoes were a little wet, probably because of his extra weight, right? Ji Yan withdrew his arm and began to search on the riverbank, smiling lightly at Zi Xi and joining the search team.

The two of them walked for a long time, and suddenly, Ji Yan suddenly stood still in one place, and Xiang Zixi was unguarded, and suddenly bumped into the other party's back.

"Why did you stop all of a sudden?" Xiang Zixi rubbed his nose, good guy, how could his back be so hard?

Ji Yan closed his eyes and listened: "Listen, there is the sound of water, faintly, just underground!" ”

Xiang Zixi's eyes lit up, and he blurted out excitedly: "Damn!" It's groundwater instead of open water! The other party dug a secret tunnel to lead the water from the bottom of the water! Well, the tuyere should probably be around here! ”

Xiang Zixi suddenly became excited, and looked around.

Suddenly, Xiang Zixi's eyes suddenly fell on a black hole cave above his head, and he immediately climbed in the direction of that cave. Although she doesn't know martial arts, her flexibility allows her to climb without the slightest obstacles. Originally, as a female thief, how could she not climb the mountain?

Xiang Zixi suddenly appeared at the entrance of the cave, and the wind behind him violently poured into the position of the cave, driving Xiang Zixi's hair and clothes to float in the direction of the cave.

"Ji Yan, look!" Xiang Zixi shouted loudly: "This cave is clearly dug out by hand, and there is a camouflage next to it!" Ordinary people won't notice this cave! ”

Ji Yan fell at the mouth of the cave, and looked at the entrance of the cave where only one person was about one person high, but when he looked inside, it was very wide, and it was indeed a manual excavation project.

"Such a big project really can't be done by one person. This shows that there are many people who are secretly digging here. Ji Yan said softly: "And the movement that the man and the woman made in the house, I'm afraid it's just to hide the movement here, because in the mountains, the villagers can't tell whether they are building a house or digging a tunnel, so they are confused." It can be seen that the excavation and construction of this huge project took two years, and it took at least hundreds of people to complete! ”

Xiang Zixi nodded slightly: "Yes, I think so too, should we go in and have a look?" ”

Ji Yan frowned slightly: "Xiangxiang." You're too curious, aren't you? I guess the other party has already blocked the road when they exit, and even if we go in now, we may not have much to gain. And it's none of our business, does it? So let's not take any chances! Don't forget, you don't know martial arts! ”
