Hot summer nights.

Under the Tiefo Ridge, there are dots of firelight, hundreds of blast furnaces stand in the town outside the mountains, and from time to time there are people pushing ores in and out.

Cheng Shilu, who was as strong as an ox, walked unhurriedly on the stone path in the mountains with a long-handled copper hammer, and had already changed into a good brocade robe, but the weather was too hot, so he untied his neckline, revealing his brown bear-like chest hair.

The villa at the end of the stone road is the private manor of the Cheng family, and as soon as he walked to the gate of the villa, a young man ran to him quickly:

"Daddy, you're back. How is the matter with the second uncle? ”

"Didn't you see Lao Tzu's disgraced face? How do you say? ”

"Uh......"

The young man's expression froze, and he didn't dare to ask more, just chased after him and smiled:

"It's okay if Dad is fine, it's not too late for a gentleman to take revenge for ten years. By the way, on the afternoon of my father's departure, a man from the rivers and lakes came over and found me privately, saying that he wanted to buy dissolved oil and open a large tomb in front of the dynasty......

Cheng Shilu raised his hand and slapped the back of his son's head, staring at him with tiger eyes:

"How the fuck do you dare to sell this thing?"

Dissolving oil is a forbidden substance approved by the imperial court, and when poured on the stone, it can dissolve most of the stone, making it brittle and easy to excavate.

Because of the fear that thieves would destroy the city wall, rob prisons, rob tombs and other transactions, the formula of dissolving oil was a top secret of the imperial court, and it was strictly forbidden for the people to refine and hide it privately.

The young man naturally knew that he didn't dare to buy this thing indiscriminately, so he leaned closer, raised his hand, and raised three fingers:

"That man's hand is not small, open this number."

Cheng Shilu paused and asked:

"How much do you want to buy?"

"Thirty barrels, not much, when you check the number with the imperial court, you can be fooled by prevarication."

Cheng Shilu's official identity is the contractor who opened an iron mine for the imperial court, because he has a relationship in the court, he sells some contraband in private, and there is nothing to do.

However, if thirty barrels of dissolved oil are used well, all of them will be soaked in the key points, and a city gate tower in the capital can be brought down in a few days, and the risk is definitely not small.

Cheng Shilu wiped the sweat from his bald head and asked:

"Are you sure it's the grave digger? Last time, someone bought it to seek revenge, collapsed a pagoda, and stoned more than 30 pilgrims to death, Lao Tzu sent several large boxes of silver before wiping his ass clean......"

The young man swore an oath: "It must be, as soon as I met me, I smelled a dead man, and my face was white, and I looked like a ...... who often went out to work in the fields day and night."

"Alright, clean hands and feet."

"Dad, don't worry, I'll do it......"

……

After Cheng Shilu finished chatting about trivial matters, he retreated left and right, and went straight to a house with a cliff wall at the back of the villa.

Inside the house is the furnishings of the study, and on the wall are rows of bookshelves, listing various books and classics.

Cheng Shilu obviously didn't have the habit of reading, so he put his portable blade on the weapon rack in the center of the room, and then went to the bookshelf, pulled a book, and pushed it to the side, revealing an arch.

Behind the arch is a stone chamber carved out of the mountain wall, and there is a secret passage leading to the mine below, which is a common 'back road' in the residence of the Jianghu people, and can quickly escape when a strong enemy attacks.

Cheng Shilu came to the stone room, lit the lamp, and saw a pair of armor on the wall.

The armor is heavy armor, silver-white overall, with wolf-headed shoulder pads and face armor, and the texture looks like it comes from the elite army, but it has been slightly damaged over time.

Cheng Shilu stood in front of the armor, first put on the pillar incense, and then picked up a golden bowl from under the armor.

The golden bowl contains rice and water, soaked in a white bead, the size of a pigeon's egg, soaked for a few days, the water in the bowl has turned into a foggy white.

Crash~

Cheng Shilu took the clip, carefully took out the white beads from the water, as if he was holding a piece of red Luo Tie, and then took the golden bowl, walked to the small bath in the stone room, poured the water in the bowl into the pool, took off his robe, and soaked the whole person into the pool, even buried his face in it......

——

At the same time, under the Iron Buddha Ridge.

The big black horse stopped in the woods, and the fluffy birds stood on the top of a large pine tree in the forest, looking out at the official road in the distance.

Underneath the pine trees, Night Terror Hall had stripped off its outer robes and was wearing a black robe of a different style.

Luo Ning stood next to him with a hat, holding a hat and a scarf in his hand, and raised his eyes to look at the mountain villa above Tiefo Ridge:

"I thought Tiefoling was just a small gateway, but I didn't expect the mine to be so big."

"Tiefoling is a mine of the imperial court, and all the output is handed over to make official swords and ordnance. Cheng Shilu is just a contractor who helps with the work. ”

While the Night Terror Hall was dressing, he was also looking at the official road outside the woods.

When he found out that Sanniang was coming with him last night, he kept paying attention, even being cautious when eating watermelon.

As a result, Sanniang listened to it for half a night, but she didn't kill her, and she didn't even say anything.

After falling asleep in the night terror, I got up in the early morning to change shifts with Bird, and I wanted to secretly go and talk to Sanniang.

As a result, as soon as he walked to the door of the room, Sanniang blocked the door, and I don't know if he was afraid that he wouldn't eat enough and wanted to catch the second game, or he was wronged and didn't open the door.

Seeing that Sanniang knew that she was exposed, she didn't force her in, and when it was dark, Sanniang covered it tightly and led the horse to set off first.

Night Terror drove the horse to Tiefo Ridge, and the bird was also being scouted on the way, and it was determined that Sanniang had been following the horse's hoof prints as a bodyguard.

Night Terror looked back a few times, and after putting on his clothes, he took the hat from Luo Nuxia's hand:

"I'll go in, you wait outside, if something happens, the bird will signal."

Luo Ning knew that Cheng Shilu was not the opponent of the Night Terror Hall, but she still reminded solemnly:

"The rabbit is in a hurry and still kicks the eagle, most people do not die in martial arts, but in the light enemy, even if they deal with the market splash, you have to fight up the spirit."

Night Terror was about to pull the towel on, but blinked again.

？

Luo Ning understood the meaning of this look, afraid that the thief would still be cranky when he went to do something, and he didn't show a cold appearance, but like a virtuous daughter-in-law who sent her husband to the battlefield, she stood on tiptoe, held the cheek of the night terror, and nodded on her lips:

"Okay, think about business, don't have distractions in your heart."

Night Terror Hall smiled, pulled up the face towel, took a deep breath, carried the black lin gun wrapped in black cloth, and walked unhurriedly to the stone steps up the mountain.

Luo Ning silently accompanied him in the mountains and forests, while reconnoitring the situation in Tiefoling to avoid being ambushed by some people.

As a sect of the rivers and lakes, it is impossible for Tiefoling to have no disciples, preliminary investigation, there are about more than 200 disciples in the entire Tiefoling, but they all live near the mine under the mountain range, serving as the supervisor and steward of the mine.

The Zhuangzi on the mountain ridge is the private residence of the Cheng family, and there are a few disciples patrolling the mountain road, so as not to let the idlers run up and disturb the master's cultivation, and there is no other protection.

The Night Terror Hall was open to the door, and he didn't walk fast, just carrying a spear and walking slowly in the moonlight, waiting for the disciples of Tiefoling to come over.

But the disciples of Tiefoling, who seemed to have been comfortable for a long time, were too alert, and they got together on the mountain road to comment on the kiln sisters in the city, and they didn't notice it when they walked to the mountainside.

Luo Ning was a little speechless about this, and when she was bored and looking around, she suddenly found that there were several figures outside an independent small house on the mountainside of Tiefoling.

The house was lonely in the corner of the mountain, far away from the house, and there were guards nearby, and the torches were not lit in the middle of the night, but they were moving things by the moonlight.

Luo Ning was slightly puzzled, and silently leaned nearby, but saw a noble son, holding a whip in his hand, who was directing Lifu to carry a pile of wooden barrels to the cart.

The distance was too far and the sky was dark, so he didn't look very carefully, Luo Ning paid attention for a while, and saw that the Night Terror Hall had already contacted the people of Tiefo Ridge, so he didn't pay attention to this inconsequential matter, and walked up the mountain quickly......
