In the academy of the Huang family mansion.

There was no one in a large courtyard that was wide as if it was half a football field. The oval pool reflected the semi-circular moon. The moonlight sprinkled in the wide academy like water, and the sound of insects sounded from time to time in the grass in the corner.

The study room in the academy is a small three-story pavilion. At this time, the study door was closed and there were no guards outside the door, but there were bright candlelights coming from the room.

On the first floor of the study.

At this time, it has been transformed into a simple room, but the corners are still filled with various bookshelves. With the bright candlelight, you can still see some traces pressed out of the bookshelf on the ground.

However, these bookshelfs have been moved to the second floor or corner, and there is no dust on the bookshelf, and books look like new books. However, there are three large and comfortable double beds in the free space, and there is also a big table in the middle of the three beds.

At this moment, some plates were placed on the table, and there were leftover food on the plate. Wang Sancai burped comfortably, threw down half of the steamed bun in his hand, grabbed a cup next to him and drank two sips of water before saying to Fang Tong and Bai Xiao who were still eating: "I'm full, take a rest first, and start working hard later."

When Fang Tong heard this, he immediately put down his bowls and chopsticks and said with some concern: "Brother, will we start tonight?"

Bai Xiao's mental state was obviously better, but he seemed to be unable to understand the conversation between the two, and he couldn't help but wonder: "What to start?"

Wang Sancai did not answer Fang Tong immediately, but suddenly stood up and tiptoed to the door, gently opened the door, looked out through the gap for a while, then closed the door and whispered: "There is no one in the yard. I don't know if there are any other places to monitor us. Anyway, we are more convenient to move at night. After you two finish eating, we will blow out the candles and make them think we are asleep."

Fang Tong suddenly lost the *** to eat again, and even stood up excitedly and couldn't wait to say, "Then let's start now!"

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

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

Leaving this sentence, he looked at Fang Tong again: "Should you wait a little longer, I can still hear the movement outside, and we will act immediately if we are a little later."

Fang Tong sat down and took a deep breath. Looking at the first floor of the study, there was three-point complexity, five-point familiarity and two-point firmness.

Bai Xiao was stunned at first, but then hesitated when he saw Fang Tong's unbearable look, and then moved his butt and leaned against Fang Tong, whispering: "You are... looking for the secret recipes left by the Pang family, right?"

As he said that, he looked at Wang Sancai vigilantly again: "I know, this is the residence of the Pang family. Although the Pang family has been destroyed for two years, their talent for talent has not been obtained by any family."

Wang Sancai laughed and scolded: "You know so much."

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

Speaking of this, he suddenly reacted, was startled, and almost fell off the chair: "You, don't you really want to steal..."

"What steals?!" Fang Tong interrupted, and his fists were clenched and he made a loud noise: "I just want to get back what I own!"

Bai Xiao quickly sat down, but pointed at Fang Tong with one hand and was full of shock: "You...you, you said you want to take back your own...?"

"No," Fang Tong interrupted Bai Xiao, turned his head and frowned and said to him, "Can you stop looking like you are useless?"

"I, I... I'm sorry." Bai Xiao immediately lowered his head, not daring 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, thinking of his experience, he shook his head and his tone became gentler: "Bai Xiao, you are very smart. You have to be a little confident in yourself, do you understand?"

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

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

Bai Xiao was silent for a moment, suddenly plucked up his courage to look at Fang Tong, hesitated and opened his mouth, and said, "I know, I know you are for my own good. I really thank you for keeping enlightenment...I, I really won't betray you..."

Fang Tong immediately closed his mouth.

Wang Sancai kept staring outside the door quietly, listening to the sound of some patrol footsteps gradually fading away, then gently closed the door and whispered: "Prepare, let's start."

Fang Tong immediately stood up, regardless of the leftover food on the table, quickly ran to a candlelight beside the wall, and blew out two candles in one bite.

The light in the room suddenly became darker.

Bai Xiao also quickly got up from the chair, and blowed out several candles like Fang Tong. When there was a burning candle left in the entire study, Wang Sancai quickly stopped him and said, "Okay, stop blowing, take the candle."

The light in the room had become very dim. After Bai Xiao trembled with the candle to Wang Sancai, his whole body trembled: "I, I am afraid of the darkness."

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

As he said that, he walked towards Fang Tong.

Fang Tong walked to the stairs on the first floor, waved to Wang Sancai and the others, and then got to the bottom of the stairs. Wang Sancai did not hesitate and followed him in with a candle in his hand. Bai Xiao looked at his body shape, then looked at the space under the stairs, and gritted his teeth, and then went down.

However, he was too fat. As soon as he got to the bottom of the stairs, there was almost no space under the stairs. Wang Sancai watched the candlelight fade and turned his head and whispered: "Fatty, go back a little, if you continue like this, we will both suffocate!"

Bai Xiao nodded vigorously and climbed back two steps. After Wang San saw that the candlelight gradually became brighter, he then set his sight on Fang Tong.

Fang Tong pressed his ear against the ground and gently tapped the floor with a finger. Wang Sancai heard Fang Tong's sound of hitting the floor very crisply, without a dull feeling. He couldn't help but frown and whisper in confusion: "It seems that there is no secret space on the ground, right?"

"Yeah." Fang Tong responded softly, but didn't say too much. Suddenly, he seemed to have found something, paused with his fingers knocking on the floor, and then moved his fingers horizontally to the wall next to him.

Wang Sancai looked at the wall, but did not see anything wrong with the wall.

However, Fang Tong turned his palm into claws and pressed it down on the wall with force. A slight "click" sound was heard, and a piece of the originally smooth wall actually sunk into it, leaving a crack about the size of a fist on the wall!

Wang Sancai's heart suddenly moved, and saw Fang Tong withdraw his hand, take out the Leng Yue dagger from his arms, and gently snatch the sunken wall carefully.

The thickness of the wall that was picked down was similar to that of the palm, but there were many uneven parts inside. Fang Tong pointed to these uneven parts, pointed to the wall that was picked down, and whispered to Wang Sancai: "Brother, look, the protruding part on this wall panel matched the stone wheel inside. When you use force, you must press it diagonally down to press it in, otherwise, these protruding parts will stagger the stone wheel tightly."

"The mechanism of the Pang family is really exquisite." Wang Sancai sighed and saw that the stone wheel in the small dark grid had six wheel axles in total. Each wheel axle was not the same in length and size, which looked a little uncomfortable.

Fang Tong just reached into her hand and was stunned and said with some difficulty: "Someone has opened this place."

"Can outsiders open such a complicated way?" Wang Sancai was shocked.

Fang Tong gently twisted the stone wheel twice and breathed a sigh of relief: "Fortunately the person who opened it did not know the rotation pattern...Brother, that person turned the stone wheel in chaos, I need to debug it."

Wang Sancai nodded and did not continue to speak. He moved the candle to a place close to the small dark grid without singing. However, he was extremely shocked: the steps to open the dark grid were harsh, and even the stone wheel was rotating was regular. No wonder the Pang family's alchemy secrets were not leaked in two years.

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

Fang Tong withdrew his hand that he had reached in and finally breathed out: "It's already done. I'll go to the second and third floors to open the remaining two stone wheel mechanisms. 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, then called Bai Xiao, "Come on, Fatty, come with me to the door."

Bai Xiao felt exhausted after lying under the stairs for so long. He struggled to come to the door, panting and complaining: "I thought there was a secret passage under the stairs... I had been lying for so long."

As Fang Tong walked up the second floor lightly, the entire first floor suddenly fell into darkness. Wang Sancai originally thought 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 breath and said softly: "Fatty, don't silence now, restrain your breathing, beware that someone outside eavesdrops on us!"

Bai Xiao immediately covered his mouth, and Wang Sancai gently opened the door a gap and looked outside. Seeing that there was no one in the academy, there was still silence, he slowly breathed a sigh of relief.

The two of them waited for a while and heard a dull "click" sound suddenly coming from the second floor. Then, they heard Fang Tong walking up the third floor again.

After a while, Heifeng, who was already sleeping on the bed, suddenly stood up and suddenly a low roar came out of his mouth. Wang Sancai was shocked and quickly opened the door and looked outside, but he did not notice any danger outside. 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 chicken's shell.

Black Wind's low roar immediately ended.

Then, Wang Sancai smelled a smell of dust.
