In the academy of the Huang family's mansion.

There was no one in a large courtyard as wide as half a football field, and the bright moon was reflected in the oval pool, and the moonlight sprinkled on the wide academy like water, and the grass in the corner still sounded from time to time with the sound of insects.

The study room in the academy is a small three-story pavilion, and the door of the study is closed at this time, and there are no guards stationed outside the door, but there is bright candlelight coming from the room.

In the first floor of the study.

At this time, it has been converted into a simple room, but the corner is still full of various bookshelves, and through the bright candlelight, you can still see some traces of the bookshelves on the ground.

It's just that these bookshelves have been moved to the second floor or corner, there is no dust on the shelves, and each book looks like a new book, but there are three large and comfortable double beds in the spare space, and in the middle of the three beds, there is a big table.

At this moment, there were some plates on the table messily, and there was still leftover food on the plates, Wang San burped comfortably, threw down half of the steamed bun in his hand, grabbed a cup next to him and drank two sips of water, and then said to Fang Tong and Bai Xiao, who were still eating: "I'm full, take a rest first, and I'll start getting busy later." ”

As soon as Fang Tong heard this, he immediately put down the dishes and chopsticks, and said with some worry: "Big brother, shall we start tonight?" ”

Bai Xiao's mental condition was obviously better, but he didn't seem to understand the conversation between the two, and couldn't help but wonder: "What to start?" ”

Wang Sancai didn't answer Fang Tong immediately, but suddenly stood up and tiptoed to the door, gently opened the door, and looked out through the gap for a while, then closed the door and replied in a low voice: "There is no one in the yard, I don't know if there are other places to monitor us, anyway, it is more convenient for us to move at night, and after the two of you finish eating, we will blow out the candle and make them think that we are sleeping." ”

Fang Tong suddenly had no desire to eat any more, and even stood up excitedly, and couldn't wait to say, "Then let's just start now!" ”

Although Bai Xiao still didn't understand what the two were saying, he also sensed that something was wrong, his face flashed with horror, and he lowered his voice: "What are you going to do?" This is the Huang family's mansion, let's not mess around! ”

Wang Sancai glared at him: "Two years ago, this was not the Huang family's mansion. ”

dropped this sentence and looked at Fang Tong again: "Wait a little longer, I can still hear movement outside, and we will act immediately if it is a little later." ”

Fang Tong sat down, took a deep breath, and looked at the first floor of the study with three points of complexity, five points of familiarity and two points of firmness.

Bai Xiao was stunned for a moment, but then put down the dishes and chopsticks, looked at Fang Tong's unbearable appearance and hesitated, then moved his butt and leaned forward to Fang Tong, and said in a low voice: "Should you be...... Looking for the alchemy cheats left by the Pang family, right? ”

As he spoke, he glanced at Wang Sancai vigilantly: "I know, this was originally the mansion of the Pang family, although the Pang family has been wiped out for two years, their housekeeping skills have not been acquired by any family." ”

Wang Sancai scolded with a smile: "You know a lot." ”

Bai Xiao was slightly stunned: "I'm afraid that no one in the entire Ice Continent doesn't know about this matter......"

Speaking of this, he immediately reacted, startled, and almost fell off the chair: "You, should you really steal ......?"

"What stolen?!" Fang Tong interrupted, and his fists were clenched: "I just want to get back what belongs to me!" ”

Bai Xiao hurriedly sat down, but pointed at Fang Tong with a face full of consternation: "You...... You, you said you want to get back your own ......? ”

"Not bad." Fang Tong interrupted Bai Xiao, turned his head and frowned at him, "Can you not always look like you're unproductive?" ”

"I, I...... I'm sorry. Bai Xiao immediately lowered his head, a little afraid to look at Fang Tong: "I didn't expect you to be the illegitimate son of the Pang family." ”

A trace of surprise flashed in Fang Tong's eyes, looking at Bai Xiao's timid appearance, remembering what happened to him, he immediately shook his head, and his tone became a little softer: "Bai Xiao, you are very smart, you have to be a little confident in yourself, understand?" ”

Bai Xiao's body suddenly stiffened, and he still didn't dare to look at Fang Tong: "You, don't worry, I will never tell others your identity." ”

Fang Tong was stunned, knowing that Bai Xiao had misunderstood what he meant, and sighed: "I'm not worried that you will betray me, I just want to do it for your good." ”

Bai Xiao was silent for a moment, suddenly mustered up the courage to raise his head and look at Fang Tong, opened his mouth hesitantly, and still said: "I know, I know that you are for my good, I really thank you for enlightening me all these days...... I—I'm really not going to betray your ......"

Fang Tong immediately closed his mouth.

Wang Sancai had been quietly watching out of the door, listening to the footsteps of some patrols gradually moving away, so he gently closed the door and said in a low voice: "Get ready, let's start." ”

Fang Tong immediately stood up, ignoring the leftovers on the table, quickly ran to a candle lamp by the wall, and blew out two candles in one go.

The light in the room suddenly dimmed.

Bai Xiao also hurriedly got up from the chair, and blew out several candles in the same way as Fang Tong, and when there was only one burning candle left in the entire study, Wang San hurriedly stopped: "Okay, don't blow it, bring the candle over." ”

The light in the room had become very dim, and after Bai Xiao took the candle to Wang Sancai's side, his whole body trembled: "I, I'm afraid of the dark." ”

Wang Sancai thought of some things, but he didn't say much, and after plugging the door with his backhand, he said casually: "Follow me." ”

As he spoke, he walked towards Fang Tong.

Fang Tong walked to the staircase on the first floor, beckoned to Wang Sancai and the two, and then drilled to the bottom of the stairs, Wang Sancai did not hesitate, and followed with a candle in his hand, Bai Xiao looked at his body shape, and then looked at the space under the stairs, gritted his teeth, and still drilled down.

It's just that he is too fat, as soon as he gets under the stairs, there is almost no space under the stairs, Wang Sancai watched the candlelight fade, turned his head and whispered: "Fatty, you go back a little, if we continue like this, we will both be suffocated!" ”

Bai Xiao nodded vigorously and climbed back two steps, only after Wang San saw that the candlelight was gradually brightening again, then he set his eyes on Fang Tong.

I saw Fang Tong put his ear close to the ground and gently tapped the floor with one finger, Wang San heard that Fang Tong's sound of hitting the floor was very crisp, and there was no dull feeling, so he couldn't help frowning and whispering: "There doesn't seem to be a dark grid on the ground, right?" ”

"Hmm." Fang Tong replied softly, but he didn't say much, suddenly, as if he had found something, his finger tapping on the floor paused, and then moved his finger sideways to the wall next to him.

Wang Sancai looked at the wall, but he didn't see anything wrong with the wall.

However, Fang Tong turned his palm into a claw and pressed it the wall, only to hear a slight "click" sound, and the originally smooth wall actually sank into a piece, leaving a crack about the size of a fist on the wall!

Wang Sancai's heart suddenly moved, and he saw Fang Tong withdraw his hand, took out the cold moon dagger from his arms, and gently picked off the sunken wall.

The thickness of the wall cut off is about the same as the palm of the hand, but there are many uneven places in the inner part, Fang Tong pointed to these uneven places, and then pointed to the wall that was cut off, and explained to Wang Sancai in a low voice: "Big brother, you see, the protruding part of this wall panel coincides with the stone wheel inside, and when you exert force, you have to press it diagonally down to press it in, otherwise, these protruding parts will be stuck in the stone wheel." ”

"The Pang family's mechanism is really exquisite." Wang Sancai sighed, and saw that the stone wheel in the small dark grid had a total of six axles, and the length and size of each axle were inconsistent, which looked a little uncomfortable.

As soon as Fang Tong put his hand in, he was stunned for a moment, and said with some difficulty: "Someone has opened this place." ”

"It's so complicated that outsiders can open it?" Wang Sancai couldn't help but be surprised.

Fang Tong gently twisted the stone wheel twice, and breathed a sigh of relief: "Fortunately, the person who opened it didn't know the law of rotation...... Big brother, that person turned the stone wheel in a mess, I need to adjust it. ”

Wang Sancai nodded and did not continue to speak, and quietly moved the candle to a place close to the small dark grid, but he was extremely shocked in his heart: the steps of opening this dark grid could not help but be harsh, and even the rotation of the stone wheel was still regular, no wonder the alchemy secrets of the Pang family had not leaked out in the past two years.

Fang Tong debugged for a while, and suddenly a dull "click" sounded, and Wang Sancai immediately asked, "What's wrong?" ”

Fang Tong withdrew his hand that had reached in, and finally exhaled: "It's already good, I'll go to the second and third floors now to open the remaining two stone wheel mechanisms, big brother, you and Bai Xiao will wait here." ”

The three of them climbed out from under the stairs, and Wang Sancai handed the candle in his hand to Fang Tong, and then beckoned to Bai Xiao: "Come fatty, follow me to the door." ”

Lying under the stairs for so long made Bai Xiao feel exhausted, and struggled to the door, panting and complaining, "I thought there was a secret passage under the stairs...... It's been so long since I've been lying in vain. ”

As Fang Tong walked lightly to the second floor, the entire first floor suddenly fell into darkness, Wang Sancai originally thought that there would be a secret passage under the stairs, but now it seems that the exquisite mechanism set up by the Pang family is far more complicated than he imagined, he took a slight breath and said softly: "Fatty, don't squeak now, restrain your breathing, be careful that someone outside is eavesdropping on us!" ”

Bai Xiao immediately covered his mouth, Wang Sancai gently opened the door a gap, looked outside, and saw that there was no half a figure in the academy, and it was still silent, so he slowly breathed a sigh of relief.

The two of them didn't wait long before they heard a dull "click" sound suddenly coming from the second floor, and then they heard Fang Tong walking up to the third floor.

After a short while, Hei Feng, who was already asleep on the bed, suddenly stood up, and suddenly let out a faint low roar in his mouth, Wang Sancai was shocked, and hurriedly opened the door to look outside, but did not find any danger outside, and then, before he could close the door, he suddenly heard a crisp cracking sound in an unknown corner on the first floor.

It's as crisp as a chick being born out of its shell.

And the low roar of the black wind immediately stopped abruptly.

Then, Wang Sancai smelled a smell of dust.
