"Cough, cough..." It was not Wang Sancai or Bai Xiao who coughed, but the black wind that suddenly calmed down. It was obviously choked and could not even scream in a low roar. It could only barely make a "whip" sound from its mouth.

Wang Sancai's heart fell back into his stomach, but he also felt that Bai Xiao was trembling beside him, so he pinched his nose and whispered: "Let's not move around first, wait until Xiaotong comes down."

In a short while, a candlelight shone down from the entrance of the stairs. Then, under the reflection of the candlelight, Wang Sancai and the others saw Fang Tong, who was a little dirty. Although Wang Sancai didn't know what Fang Tong had encountered on it, it was not difficult to guess the difficulty of him opening the two mechanisms above, looking at his dirty appearance.

However, before the two of them spoke, Fang Tong said first: "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 just become too dirty."

While talking, Fang Tong finally noticed Heifeng who was coughing, and quickly greeted Wang Sancai and ran towards Heifeng.

The place where Black Wind is located is Fang Tong's big bed, but at this moment, the place where it is staying is covered with white dust, and the black hair is covered with dust.

Wang Sancai pulled Bai Xiao and took the candle handed over by Fang Tong. He saw Fang Tong pick up Heifeng and stroke it twice, then handed it to Bai Xiao and said, "You can help me comfort it first."

Bai Xiao quickly took Heifeng and gently patted the dust on his body. At the same time, he was babbling at it for a while. Heifeng immediately stopped coughing, but there was still a faint dry cough in his throat from time to time.

At this time, Fang Tong was already standing in the position where Hei Feng was on the bed. Wang Sancai heard Hei Feng’s reaction and asked casually: “What did you say to it? Don’t hold it back.”

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

Wang Sancai looked down at Heifeng. Seeing that it was choked, his whole body was trembling but insisted on not making a sound, he couldn't help but feel soft. He touched it gently twice. When he turned around, he saw Fang Tong had already cut out a thin stone slab on the floor. Then, he touched it in it and put it back.

After he turned around and jumped out of bed, he stuck out his hand and handed it to Wang Sancai: "The key has been found, I will go outside and open the door first."

Wang Sancai saw that the key was in a strange shape, just like the previous stone wheel, with the six teeth on it different lengths and thicknesses. On each tooth, there were some small details, either concave or convex. What's important is that the key looked like wooden.

"The basement is still outside?" Wang Sancai sighed helplessly: "I have been busy for so long and I just found the key."

As he said that, he pointed to the brick on the ceiling that had just been returned by Fang Tongan: "If someone took the stone brick away directly, wouldn't he find the key in an instant?"

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

After saying that, Fang Tong stuffed the key to Wang Sancai, and while taking off his clothes, he said, "I will pretend to go out to pee later and see if there are people and the entrance. If there is no problem, we will go there immediately when I come back. I need your help."

Wang Sancai nodded, and suddenly felt aroused his heart. He remembered that Bai Xiao blocked the stairs and weakened the candlelight, and immediately asked: "That entrance should be the basement."

"No, the entrance to the basement is still in the study, and the entrance outside is just a machine door that needs to be opened with a key." Fang Tong 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." Wang Sancai responded. Seeing that Fang Tong had already walked out of the room, he walked to the corner of the wall to take a candle, ignited it with the candle in his hand, and placed it on the table casually.

Immediately afterwards, he closed his eyes and put the burning candle in his hand into the warehouse. He saw that there was a prop - a burning candle in the warehouse.

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

Not long after, the door was opened. Fang Tong did not come in, but waved to the inside of the house and whispered: "Come out, there is no one outside."

Wang Sancai immediately ignored the candles on the table and walked out to the door, and said to Bai Xiao: "You have too big goals, so don't go out. Let's wait here now."

Leaving this sentence, Wang Sancai walked out of the room without waiting for Bai Xiao to answer.

The moonlight outside was still bright, and the visual range was much stronger than that in the house. When they walked out of the room, the two of them were paying attention to the surroundings and heading towards the corner near the pond, which was covered with grass. However, Wang San noticed that in the grass behind a tree, the soil in the corner was slightly higher.

Sure enough, Fang Tong walked around the tree and as soon as he walked to the corner of the wall, he immediately dug up the piece of soil with the Leng Yue dagger and said, "Brother, help me and dig some nearby."

After saying that, he gestured to Wang Sancai to a general range.

Wang Sancai didn't say much and immediately took out the seal short sword. Both of them were cultivators. With the help of their vitality, they dug very quickly. Within ten minutes, a small pit less than half a meter deep was dug. The pit was about one meter long and wide. There were two combined white stone slabs below, which was enough space for Bai Xiao to jump down.

Hiding behind the big tree, the two of them seemed not so obvious. Fang Tong jumped down and lifted up the two stone slabs. He immediately revealed a staircase that was leading to the ground. He pointed to the stairs and whispered: "The last mechanism that needs a key is below."

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 entered the room for a long time, and the oxygen has been exhausted. Don't go down first, try this candle."

Fang Tong was about to go down, but when he heard this, he was stunned: "Oxygen?"

Wang Sancai couldn't explain to him, so he said directly: "Don't worry about so many things. Just remember that if the candle is put down and extinguished, you must not go down."

Fang Tong didn't dare to spend more time here, so he nodded and took the candle. He tried it according to Wang Sancai's method. After finding that the candle was not extinguished, he turned his head to Wang Sancai and said, "Brother, I'll go down and open the door. Please help me with the wind."

Seeing Wang Sancai nodding, Fang Tong then picked up Leng Yue and walked down the stairs with a candle.

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

Wang Sancai was about to ask him if he had encountered any danger below, but suddenly he thought that when he was in Lin Nan City, Fang Tong said that opening the basement entrance would require blood from the Pang family, so he felt relieved.

Fang Tong nodded to Wang Sancai as soon as he came up, closed the two stone slabs, and said at the same time: "Okay, I have opened the entrance to the basement. I haven't pulled out the key. Come over when we leave. Now, my brother will help me bury the place again."

Wang Sancai didn't say anything nonsense, and immediately buried the small pit with Fang Tong. The landfill speed was much faster than the excavation speed, but it took some time to insert the grass into the soil again.

Although this area will definitely not be restored to its original state, it is blocked by big trees, and most people cannot see this corner.

As soon as the two returned to the study, Fang Tong suddenly got to the entrance of the stairs again. Wang Sancai used a candle to help him shine, and saw Fang Tong knocking on the wooden board under the stairs again.

However, the sound of the knocking this time was obviously hollow and lengthy!

Fang Tong lifted the wooden board along the wall and saw a big round hole with a diameter of two meters below!!

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

After confirming that the door was closed, Wang Sancai and the other two climbed down the ladder. Fang Tong walked at the end and locked the wooden board.

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

Subconsciously, Wang Sancai shone the light of the tactical flashlight towards the entrance of the cave where the three of them came down. He saw an iron round block that matched the size of the cave entrance and was very thick across it. On the left side of the block, an iron block strip of wrist was connected. Wang Sancai looked along the iron block strip and found that it extended to a long distance, and the direction was exactly the corner where the two of them went out to dig the hole!

What surprised Wang Sancai even more was that he found that the ceiling above him was made of thick pig iron-like substances. Then, he discovered again that not only the ceiling, but also the ground was made of this pig iron-like substances!

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

Fang Tong also jumped off the ladder, and saw Wang Sancai's puzzled face with the faint candlelight, and immediately said: "Brother, this basement is cast with rare 'melting stone', with a thickness of nearly one foot. Even the masters of the late stage of the innate stage will definitely not be able to break it. Without the key and the blood of my Pang family, the specially made secret doors, the round selting stone we came down will never move to the present place."

Before Wang Sancai could speak, Bai Xiao suddenly started to be surprised and said: "Oh my God, it's actually a rare 'melting stone'. I read the book that melting stone comes from the Fire Continent, and a pound of melting stone can be exchanged for five top-grade Yuan stones!"

But when he said this, Bai Xiao was suddenly stunned and his tone became even more excited: "You said that secret door needs blood to be activated? Is there a 'memory crystal' hidden in the secret door that can remember bloodlines?"

Fang Tong immediately smiled: "You are indeed very smart. The material of the secret door is still melt stone, but a piece of memo crystal as thick as a thumb in the keyhole."

Bai Xiao seemed to be unable to bear it anymore: "Oh my God, the memo crystals as thick as a thumb are more expensive than a hundred kilograms of melt stone. I also heard that the Pang family is very rich, but I really didn't expect that they are so rich!!"
