"So the hydraulic mechanism in this treasure has a total of three different states." Bai Xueyin concluded, "It only allows water to enter but not drains out, it does not allow water to enter and does not drain out, and it only drains water but does not enter."

"This is about before we broke in." Lan Qiao nodded. "Now that the stone wall next to the water gate has been destroyed by me, the three states are: a lot of water but no leakage, a small amount of water but no leakage, and a flood of water.

It tends to balance with water leakage.”

Bai Xueyin said with lingering fear, "So the water in this treasure will only become more and more. If we don't find a way out in time, all of us will drown alive."

As she talked, she looked around and found that there were stone doors connecting to other spaces in the front, left, and right directions of the stone chamber. She wondered, "Why are there so many doors, it's like a maze."

Knowing that she was afraid, Lan Qiao waded through the stone door on the left and entered a new stone room.

Bai Xueyin held the corner of his clothes with one hand and followed him closely. Seeing that this stone room was almost exactly the same as the one just now, she couldn't help but be even more surprised.

Lan Qiao led her through two more stone chambers, and finally determined that this was a strange maze filled with mechanisms. He comforted her and said, "Don't worry, since this Xixia treasure is a mechanism array, there must be a mechanism room to control these mechanisms."

"The agency room," Bai Xueyin said in confusion, "Isn't this a place where the Xixia people hide their treasures? Why do you need so many agencies?"

"Anti-theft is of course one of the purposes." Lan Qiao thought, "But I was also thinking just now that it is not impossible if the builder of the treasure intends to build this place into a secret military base."

He picked up one of Bai Xueyin's hands and gestured in her palm while saying, "This is the Hexi Corridor. If we want to resist foreign enemies, Ganzhou City, the choke point, is the top priority. However, Ganzhou is an isolated city and cannot bear it.

The enemy has been attacking for a long time, so this treasure guarding the upper reaches of the Black Water is an excellent military fortress."

Seeing that Bai Xueyin was still confused, Lan Qiao further explained, "I guess you don't understand what the power of the corner is. Let me tell you this, the space in this treasure is so large that it can station tens of thousands of elite soldiers, and the hoard can exceed

It has a year's worth of food and grass, and it is located on a hillside that is easy to defend and difficult to attack. It can also cut off the black water from the upper reaches, and then open the gate to release the flood, killing any enemy troops who dare to besiege Ganzhou City."

Only then did Bai Xueyin understand what Lan Qiao meant. She smiled and said, "So if I were the general of Xixia, if I saw the enemy coming to attack the treasure, I could use the mechanisms of these stone gates and water gates to defeat the enemy."

"So smart." Lan Qiao smiled and touched her head and said, "You can teach a kid."

Bai Xueyin pushed his hand away with an angry look, "What? You're talking like a child."

Lan Qiao smiled casually, and continued to wade forward while saying, "So a secret military fortress like this usually has a mechanism room for the commander to control this huge mechanism array."

Bai Xueyin said thoughtfully, "Having said that, where is this agency room?"

Lan Qiao smiled slightly and reminded her, "Do you still remember the stone chamber we came down to? In the square well above the head of the stone chamber, there was a huge copper shaft inserted obliquely from the well wall to control the opening and closing of the water gate mechanism.

"

Bai Xueyin nodded and said, "This is the first time I have seen such a huge copper axis. How could I not remember it?"

"A large mechanism like this is usually not too far away." Lan Qiao said, "In other words, I think the other end of the copper shaft is probably the mechanism room we are looking for. But just now

There is no shortcut to the stone chamber, so we can only take a detour."

Bai Xueyin looked around and said, "How to get around?"

Lan Qiao said, "I remember the approximate location of the copper axis. As long as you look in that direction, you won't be wrong."

Bai Xueyin frowned and said, "But I remember that the copper shaft seems to be quite high. We are only looking for it here, I'm afraid."

"So we need to go to the upper floor first." Lan Qiao pointed to a dark hole more than two feet above his head, "Junior sister."

Bai Xueyin had a tacit understanding with him for a long time, and without waiting for him to say anything, she took the initiative to squat down and put her palms up on her shoulders.

Lan Qiao bent his legs and stood on her hand, and the two of them exerted their strength together. Lan Qiao soared into the sky like a cannonball, passed through the three-foot-wide hole, and entered the stone chamber on the second floor.

He turned back and waved to Bai Xueyin. Bai Xueyin jumped up with luck and jumped to the highest point, which was still seven or eight feet away from the second floor.

Lan Qiao stretched out an arm, condensing his true energy at the same time, and the yin and yang bracelet on his wrist produced a huge traction force. Bai Xueyin used the force to do another somersault, and flew up smoothly.

Relying on their memory of the location of the copper axis, the two walked along the wall. In less than a quarter of an hour, they found a crack in the wall that could be passed through.

Lan Qiao clicked his tongue and said in wonder, "This crack is like a natural formation. The designer of the treasure must be a great master."

He leaned into the crack, and within thirty steps, he saw a locked stone door.

"This crack is so narrow that only one person can pass through it at a time. Even if it is discovered by the enemy, it can be guarded for a long time." Lan Qiao played with the rusty copper lock. With a little luck, he unlocked the copper lock.

Determined.

Pushing open the stone door, the two walked into a large stone chamber twenty steps square. The stone chamber was filled with various mechanisms, and the huge copper shaft that controlled the water gate mechanism was also among them.

"That's right." Lan Qiao said with shining eyes, "This is the mechanism room of the Treasure Array."

He did not look at the complicated mechanisms, raised the luminous pearl and walked along the wall first. Sure enough, he found what he was looking for on the back wall of the stone room - the general diagram of the mechanisms of the Xixia treasure.

Lan Qiao greedily looked at the machine diagram carved on the stone wall, and said with a smile, "Since it is the headquarters, how can there be no machine map?"

This general drawing of the mechanism shows a labyrinth-like underground space. It is divided into three floors, upper, middle and lower. Each floor has ninety-nine and eighty-one stone chambers. The purpose of each stone chamber and the mechanisms in it are also shown on the map.

various marks.

"What an unexpected harvest." Bai Xueyin said happily, "With this, will we be able to find the hidden treasure before the Flower Demon Girl and others?"

"Nine-Nine Three Talents Formation." Lan Qiao didn't know whether he heard Bai Xueyin's words. He read the small words engraved in the corner and said happily, "Look, we are here now. According to the Three Talents Formation, there is a crack in the wall of the room outside.

The stone chamber should be called Di Sijiu, while the stone chamber we first entered was called Ren Liujiu."

Bai Xueyin looked at the dazzling various marks on the map and couldn't figure out the meaning of each mark for a while. He could only say, "Which of these marks is the treasure room?"

"Tianjiuqi." Lan Qiao pointed firmly at a stone chamber drawn on the third floor on the map. "There is a circle drawn on this stone chamber. It should be where they store their treasures."

"Then let's go look for the treasure now." Bai Xueyin looked at the route on the map and said, "It shouldn't even take half an hour to get there from here."

"No." Lan Qiao smiled and shook his finger, "It's rare that we have the right time and place. How can we just get the treasure? First, help Ling Xiaozi rescue the Xixia Princess, and then save the demons and witches from Erqihui. They have grudges and grudges.
