A very abrupt cracking sound came into Zuo Qian's ears, Zuo Qian took back the foot that was about to step out, carefully observed the place he stepped on, and found that there was a trace of spider web-like cracks on the floor, this discovery made Zuo Qian's eyes light up, and he immediately lowered his body and wiped the dust on the cracked floor with his hands.

When Zuo Qian wiped off the dust on it, he carefully looked around the cracked floor, but he didn't find anything, so he knocked on the floor with his hand, and it turned out that there was really a door when he knocked on it, only to hear the sound of 'dong dong dong', which was very crisp, unlike the dull sound of the physical floor.

Listening to the sound of the ground, Zuo Qian immediately increased his strength, and slapped the cracked floor with his right hand, only to hear a 'click', the floor shattered, revealing a palm-sized square hole inside, the square hole was only five inches deep, just revealing a pull ring inside.

After seeing the pull ring, Zuo Qian didn't hesitate, and directly pulled the pull ring up, only to hear the sound of the mechanism opening, but in a few breaths, a wall behind Zuo Qian suddenly revealed a rectangular doorway, which was neatly repaired.

Zuo Qian turned his head and looked at the black hole, as if a monster opened a huge mouth there, Zuo Qian saw that it was black inside, and he didn't go in first, because he didn't know if there was danger, so he went out of the room first, went outside to make a simple torch and walked in again, took out the fire fold in his arms and blew it, and began to light the torch in his hand.

Zuo Qian walked to the door that seemed to be a secret passage, settled down and walked inside, although the entrance of the cave was not very big, it was enough for an adult to enter and exit.

After entering the hole, Zuo Qian picked up the torch in his hand and searched in front of him, in addition to the common point of all the dusty secret passages, the inside was not damp, but it looked very dry, so Zuo Qian asked all the way about the smell of mold, all the way carefully walked in, when walking in the secret passage, Zuo Qian felt more and more down.

However, when Zuo Qian hadn't walked out of the secret passage for a long distance, Zuo Qian saw through the light of the torch that there was a big iron door in front of him, Zuo Qian looked at the big iron door and found that this was another machine door, but the mechanism of this machine door was in the open and was not hidden.

After Zuo Qian saw this mechanism, it was like the mechanism technique that Jinyiwei talked about during his training, like this mechanism, Zuo Qian observed that his mechanism lock was using the Five Elements Bagua and the like, just to let people be able to crack his layout in order to open the iron door.

After looking at the mechanism, Zuo Qian began to fiddle with the lock.

"There is only gossip on it, is it hiding the five elements?"

After Zuo Qian meditated on the lock for a long time, he began to move.

After moving for a long time and not seeing any reaction to the mechanism lock, Zuo Qian simply restored the lock again, but after Zuo Qian restored the patterns on all the mechanism locks, he heard a 'click' sound. Zuo Qian thought at first that he had touched some dangerous mechanism, but he saw that the big iron gate was rising.

"Hua Cha, what is going on!" Zuo Qian looked at the slowly rising iron gate with a black line.

Zuo Qian thought in his heart, maybe the person who made this mechanism was cautious, because of such a mechanism, everyone is thinking as complicated as possible, and what no one knows is that as long as the mechanism that was moved just now is restored, this time Zuo Qian was able to open the iron door, and it was completely the luck of stepping on shit.

Zuo Qian, who was standing outside the big iron gate, held a torch to watch the big iron gate rise there.

After a 'coax', the big iron gate stopped, and a dazzling light shone into Zuo Qian's eyes, which stabbed Zuo Qian's eyes for a while before he eased up.

When Zuo Qian looked at the scene inside, he was stupid when Zuo Qianle was broken, only to see a hole in the ground that was three or four zhang in size, and there were rows of silver and various jewels neatly placed in it to illuminate the entire hole as if it were daylight.

Zuo Qian was in a daze at first, and then walked inside, Zuo Qian walked all the way and touched the silver, and the excitement in his heart almost made him faint with excitement, just when he was lost in the light of silver and jewelry, Zuo Qianxin was excited, bit his tongue hard, and forcefully sobered himself up.

"With so much silver and jewelry, it can be said that all of them are mine now," Zuo Qian muttered to himself.

It would be false to say that you are not excited to see so much silver, especially the first time you have seen so much silver.

Zuo Qian casually opened a few boxes and found that they were all big ingots, and they were all one hundred taels and one hundred taels, more than the ten taels and fifty taels of silver on the shelf.

After reading the silver, Zuo Qian went to the shelves with books in rows.

After walking in, Zuo Qian saw clearly, there were seven books on the shelf, namely two copies of "Forging Metallurgy" and five copies of "Crossbow Machine Encyclopedia", after seeing these two books, Zuo Qian's eyes lit up, and he first opened the crossbow machine Encyclopedia, because when he was in Jinyiwei, Zuo Qian knew that Daming had three ace troops, five military camps, three thousand battalions and the most powerful Shenji battalion in the field.

The Shenji was first equipped with the most powerful crossbow machine in the Ming Dynasty, and later equipped with firearms and various artillery (the Shenji battalion in the Ming Dynasty was equipped with a format of firearms, which was more than 200 years ahead of the world at that time, and it was also the first to put firearms into battle).

Seeing the crossbow machines in the "Complete Picture of Crossbow Machines", Zuo Qian likes it from the bottom of his heart, if he really makes all the crossbow machines inside, it is simply sweeping all the armies, not to mention anything else, just the light crossbow inside, although the range is not far, but if the group army is fighting, everyone is equipped with one, how terrifying it is, the other party was knocked to the ground by himself before he got close, which is far more convenient than the bow and arrow.

After Zuo Qian finished reading the five "Crossbow Machine Complete Maps", he looked at "Forging Metallurgy" and found that there were many forging techniques in it that were unprecedentedly in the entire Ming Dynasty, including the Mo knife forging inside, which had been lost in the Ming Dynasty, but he didn't expect to be discovered by himself here, and Zuo Qian had an indescribable sense of pride in his heart.

Since the beginning of the Five Dynasties and Ten Kingdoms of the Northern and Southern Dynasties, except for the early Northern Song Dynasty, the entire land of China has been trampled by the barbarians of Fanbang, and then it was not until the Emperor Hongwu that the Central Plains and the current Ming Dynasty territory were recovered, almost every son and daughter of Yan and Huang Huaxia descendants want to be able to reproduce the prosperity of the Han and Tang Dynasties, but today after seeing the Mo knife map, Zuo Qian, who opened his heart belongs to his enthusiasm, originally planned to just want to be a happy Cangshun Bo Zuo Qian, after seeing the Mo Dao map, a fire in Zuo Qian's heart was ignited, that is a kind of integrity of the famous clan, since he was just a small scout scout in the Ming Dynasty, now since he has given me this opportunity, so long let the spark of China burn in this world.

But then there was a headache for Zuo Qian, that is, he and Chen Mianmian didn't understand these things, it seemed that they had to slowly figure it out in the future, after Zuo Qian thought about it, he still put these books here, and when they were useful one day, he would hand them over to the right people.

Zuo Qian asked Chen Mianmian how much money they still have now, Chen Mianmian said that the total amount of about 300,000 taels plus the sale of real estate and the emperor's reward is about 300,000 taels, but they are all silver tickets, after coming to Heishui North, Zuo Qian found that the silver tickets do not work here, unless they go to a place fifty kilometers away to change, and now it is good, with so much cash, it is enough for Zuo Qian to do a lot of things.

After reading these things, Zuo Qian exited the secret room, he was going to tell Chen Mianmian about this, according to Zuo Qian's words, he could not believe in himself but also could not disbelieve Chen Mianmian, and Chen Mianmian was the only person he could discuss now.

When Zuo Qian came to the outer hall of the City Lord's Mansion, it was already time for the sun to set, but Chen Mianmian hadn't come back yet, and the bored Zuo Qian ran to the gate of the City Lord's Mansion to squat, wanting to see when Chen Mianmian would come back. However, Zuo Qian didn't wait long, about the time of a cup of tea, Chen Mianmian came back in a carriage.

After Chen Mianmian returned to the City Lord's Mansion, Zuo Qian helped Chen Mianmian unload the things on the truck, but he didn't speak, because he knew that the partition wall had ears, and it was not easy to reveal such a big thing casually.

Not long after, the two unloaded the goods on the car, Chen Mianmian carried some food in his hand, and Zuo Qian came to Zuo Qian's cleaned up kitchen, and when he was cooking, Zuo Qian told Chen Mianmian about the secret room, but Chen Mianmian didn't have much reaction when he got the news.

"Since there is so much silver, then it is easy to make use of it" Chen Mianmian answered Zuo Qian's question very plainly, as if it was a trivial thing that he was usually doing.

Seeing Chen Mianmian like this, Zuo Qian was also a scoundrel for a while, so he had to shut up.

After the two had dinner, Chen Mianmian took out a knife, which was the Yanling knife that Zuo Qian requested.

Zuo Qian took the Yanling knife, pressed the goose wings and retracted the spring, only to hear the sound of the knife out of the sheath, the sound is very crisp, the knife body is streamlined, the workmanship is very good, and it is also very appropriate to hold in the hand, without the slightest sense of abruptness.

"Good knives"

"Well, it is indeed a good knife, it cost nearly ten taels of silver, and it is made of 100 forged steel, which is suitable for the most yang and rigid knife method of opening and closing and attacking fiercely," Chen Mianmian said with squinted eyes on the side.

"Oh, but it's worth the money," Zuo Qian said with a knife and a glance at Chen Mianmian.
