"Cough, cough ......" It was not Wang Sancai or Bai Xiao who coughed, but the black wind that suddenly quieted down, it was obviously choked, and it couldn't even scream out of a low roar, and it could only barely make a "woo" sound in its mouth.

Wang Sancai's heart fell back into his stomach, but he also felt that Bai Xiao beside him was already trembling, so he pinched his nose and whispered: "Let's not move for the two of us, wait for Xiaotong to come down." ”

After a while, there was candlelight shining down from the staircase, and then, under the reflection of the candlelight, Wang Sancai and the two saw Fang Tong, who was a little disgraced, although Wang Sancai didn't know what Fang Tong encountered on it, but looking at his gray face, it was not difficult to guess how difficult it was for him to open the two mechanisms above.

It's just that without waiting for the two of them to speak, Fang Tong preemptively said: "Fortunately, the two stone wheels on it have not been opened, but they have not been wiped and sorted out for two years, and they have become too dirty." ”

While speaking, Fang Tong finally noticed the black wind that was coughing, and hurriedly said hello to Wang Sancai and ran towards the black wind.

The place where the black wind was was Fang Tong's big bed, but at this moment, the place where it was staying was already covered with white dust, and the black hair was also drenched in dust.

Wang Sancai pulled Bai Xiao over, took the candle handed over by Fang Tong, and saw Fang Tong pick up Hei Feng and stroke it twice, then handed it to Bai Xiao and said, "You help me appease it first." ”

Bai Xiao hurriedly took the black wind, gently patted the dust on his body, and babbled at it for a while, the black wind immediately stopped coughing, but a faint dry cough still sounded in his throat from time to time.

At this time, Fang Tong was already standing in the position where Hei Feng was originally on the bed, and Wang San heard Hei Feng's reaction and asked casually, "What did you tell it?" Don't suffocate it. ”

Bai Xiao immediately replied: "I told it that we are doing something very important now, and if it doesn't feel so uncomfortable, try not to make a sound." ”

Wang Sancai glanced down at Hei Feng, and saw that its whole body was shaking but insisted on not making a sound, his heart couldn't help but soften, and he gently touched it twice, and when he turned around, he saw that Fang Tong had already picked out a thin slate on the floor, and then, after touching it inside, he put the slate back again.

After he turned around and jumped out of bed, he stretched out a hand and handed it to Wang Sancai: "The key has been found, I'll go outside and open the door first." ”

Wang San saw that the shape of this key was strange, just like the previous stone wheel, the six teeth on it were different in length and thickness, and on each tooth, there were some small details that were concave or convex, and the important thing was that the key looked like it was wooden.

"The basement is still outside?" Wang Sancai sighed helplessly: "I've been busy for so long, but I just found the key." ”

As he spoke, he pointed to the brick on the ceiling that had just been returned by Fang Tong'an: "If someone directly takes this stone brick away, won't they find the key all of a sudden?" ”

Fang Tong suddenly shook his head and said: "No, the structure of the study is very special, you must complete each step to open the stone bricks smoothly, if you only know the location of the key hidden, if you want to open it by external force, some small mechanisms inside will directly turn the key into a pile of useless wood chips at the first moment." ”

After speaking, Fang Tong stuffed the key to Wang Sancai, and while taking off his clothes, he said: "Wait a minute, I'll pretend to go out to pee, and by the way, see if there is anyone and the place to enter, if there is no problem, we will go over immediately when I come back, I need your help." ”

Wang Sancai nodded, and suddenly his heart moved, remembering that Bai Xiao blocked the staircase before the candlelight weakened, and suddenly asked, "That entrance should be the basement." ”

"No, the entrance to the basement is still in the study, and the outside entrance is just a trap door that needs to be opened with a key." Fang Tong even threw his boots aside, then quickly washed his face, and was about to run towards the door: "I'll go out and have a look now." ”

"Go ahead." Wang San answered, and seeing that Fang Tong had already walked out of the room, he walked to the corner of the wall and took a candle, lit it with the candle in his hand, and put it on the table casually.

Then, he closed his eyes and put the burning candle in his hand into the warehouse, and saw that there was just one more prop in the warehouse - a burning candle.

Bai Xiao looked at Wang Sancai strangely while calming the black wind, especially at the moment when the candle disappeared, he couldn't help but be stunned for a moment.

It didn't take long for the door to be opened suddenly, Fang Tong didn't come in, just beckoned to the house, and said softly: "Come out, there is no one outside." ”

Wang Sancai immediately ignored the candles on the table, and immediately walked out towards the door, and said to Bai Xiao at the same time: "Your goal is too big, don't go out, wait here now." ”

Dropping this sentence, before Bai Xiao could answer, Wang Sancai had already walked out of the room.

The moonlight outside was still bright, and the visual range was much stronger than that inside the house, and when they walked out of the room, the two of them walked towards the corner near the pond while paying attention to their surroundings, where there was a bush, but Wang San noticed that in the grass behind a tree, the dirt in the corner of the wall was slightly higher.

Sure enough, Fang Tong walked around to the back of the tree, and as soon as he walked to the corner of the wall, he immediately dug up this piece of soil with the cold moon dagger, and said, "Big brother, help me, just dig some around here." ”

After speaking, he gave Wang Sancai a general range.

Wang Sancai didn't say anything, and immediately took out the seal short knife, both of them were cultivators, and the speed of digging with the help of Yuan Qi was very fast, and it didn't take ten minutes to dig a small pit less than half a meter deep, the length and width of the pit were about more than one meter, and there were two white stone slabs together, and the space was enough for Bai Xiao to jump down.

Hidden behind the big tree, the two of them didn't seem so obvious, Fang Tong jumped down first and lifted the two stone slabs, and immediately revealed a staircase that led down to the ground, pointing to the stairs and whispering: "Below is the last mechanism that needs a key." ”

Wang Sancai threw the wooden key to Fang Tong, and immediately took out the burning candle from the warehouse and handed it to him: "No one has gone in for a long time below, and the oxygen has been exhausted, don't go down yet, try it with this candle." ”

Fang Tong was about to go down, but when he heard this, he couldn't help but be stunned: "Oxygen? ”

Wang Sancai couldn't explain to him, so he said directly: "Don't worry so much, you just need to remember that if the candle goes down and goes out, you must not go down." ”

Fang Tong didn't dare to waste more time here, so he immediately nodded and took the candle, tried it according to Wang Sancai's method, and after finding that the candle was not extinguished, he turned his head and said to Wang Sancai: "Big brother, I'll go down and open the door, you can help me let the wind go up." ”

Seeing that Wang San nodded, Fang Tong picked up Leng Yue and walked down the stairs with a candle.

About twenty minutes later, just when Wang San couldn't wait, Fang Tong finally walked up again, only the difference was that there was a new scar on the wrist of his left hand!

Wang Sancai was about to ask him if he had encountered any danger below, when he suddenly thought that when he was in Lin Nancheng, Fang Tong said that opening the entrance to the basement still needed the blood of the Pang family, and he was relieved.

As soon as Fang Tong came up, he nodded to Wang Sancai, closed the two stone slabs with his hand, and said at the same time: "Okay, the entrance to the basement has been opened by me, I didn't pull the key off, let's come back when we leave, now the eldest brother will help me bury this place again." ”

Wang Sancai didn't have any nonsense, and immediately reburied the small pit with Fang Tong, the speed of filling was much faster than the speed of excavation, but it took some time to reinsert the grass into the soil.

Although this area will certainly not be restored to its original state, it is blocked by large trees, and ordinary people cannot see this corner.

As soon as the two returned to the study, Fang Tong suddenly got to the staircase again, and Wang San took a candle to help him shine it again, and saw Fang Tong knocking on the wooden board under the stairs again.

It's just that this time the sound of percussion is obviously empty and verbose!

Fang Tong lifted the wooden board along the wall skin, and saw a large round hole with a diameter of two meters exposed underneath!!

Wang Sancai noticed that there was a circle of metal similar to pig iron around the entrance of the cave, and when he poked the candle into the hole, he found that there was a ladder at the entrance of the cave, and the candle was not extinguished!

After making sure that the door was closed, Wang Sancai and the three of them climbed down the ladder, and Fang Tong walked at the back and buckled the plank down.

As soon as Wang Sancai jumped below, he found that there was a musty smell here, but the candle was not extinguished, and he could still breathe, but the candle was about to burn out, so Wang San thought for a moment and simply turned on the tactical flashlight.

Subconsciously, Wang Sancai shone the light of the tactical flashlight towards the entrance of the cave where the three people came down, and saw that on the ceiling on the right side of the hole, there was a thick iron round that matched the size of the hole, and on the left side of the circle, there was a wrist-thick iron block, Wang Sancai looked along this iron block, and found that it had been extended to a long distance, and the direction was exactly the corner where the two went out to dig the hole before!

What surprised Wang Sancai even more was that he found that the ceiling above him was all made of thick pig iron-like substance, and then, he found out again that not only the ceiling, but even the ground was made of this pig iron-like substance!

Bai Xiao had never seen the light of the tactical flashlight, and couldn't help but point curiously: "What is this?" Why is it like sunshine? ”

Fang Tong also jumped down from the ladder, and saw the puzzlement on Wang Sancai's face by the faint candlelight, and immediately said: "Big brother, whether it is the ceiling or the ground, as well as the surrounding walls, this basement is all cast with rare 'melt stone', with a thickness of nearly one foot, even the masters of the late congenital stage will definitely not be able to break it, without the key and the blood of my Pang family's specially made secret door, this round melt stone in the place where we came down will definitely not move to this place now." ”

Before Wang Sancai could speak, Bai Xiao suddenly preemptively surprised: "Oh my God, it's actually a rare 'melt stone', I read the book that the melt stone comes from the Fire Continent, and a pound of melt stone can be exchanged for five high-grade yuan stones!" ”

But speaking of this, Bai Xiao was suddenly stunned, and his tone became more excited: "You said that the secret door needs blood to trigger?" Could it be that there is a 'memory crystal' that can remember the bloodline in the secret door? ”

Fang Tong immediately smiled: "You are indeed very smart, the material of the secret door is still melted stone, but a thumb-thick memory crystal is added to the keyhole. ”

Bai Xiao didn't seem to be able to stand it anymore: "Oh my God, the finger-thick Yijing is more expensive than a hundred catties of melted stone, I also heard that the Pang family is very rich, I really didn't expect to be rich to this extent!" ”

Fang Tong sighed, and just wanted to say something, but Wang Sancai, who had been silent for a long time, suddenly frowned and said in confusion: "Xiao Tong, didn't you say that the basement is full of the Pang family's previous statistics?" Now don't talk about those statistics, let alone your family's alchemy cheats, I looked around, and I didn't even find a piece of paper!! …… Has anyone already been here? ”
