Long Jiansheng took out something about the size of a palm, wrapped in a black cloth, from his backpack and handed it to the old ghost.

The old ghost took the package, looked up at each other with everyone, and without saying a word, immediately untied the layer of black cloth wrapped outside, and when the things wrapped in the black cloth were displayed in front of everyone, everyone was taken aback. Inside was a golden swallow carved out of gold.

Under the illumination of the light, the golden swallow reflects the golden light, and the whole golden swallow is extremely delicately carved, vivid, lifelike, and looks like a live bird.

And on this golden swallow's body, it is also engraved with inscriptions.

When the old ghost saw this Jin Yan, his face suddenly changed slightly, he immediately raised his head and asked Long Jiansheng, "Did your stepfather tell you where you got this thing?" ”

Long Jiansheng nodded and replied, "Father-in-law said that this golden swallow is from the Mausoleum of Qin Shi Huang. ”

Listening to Long Jiansheng's answer, Wen Qingshan on the side suddenly understood something, and said: "According to classical records, Xiang Yu led hundreds of thousands of troops to dig the imperial tomb, and suddenly a golden swallow flew out of the imperial tomb, this golden swallow has been flying south, I don't know where to go, after hundreds of years, the Three Kingdoms period of the southern Taishou Zhang Shan got a golden swallow, he judged from the text carved on the golden swallow that it was from the mausoleum of Qin Shi Huang. Could this be the magical golden swallow? ”

Out of curiosity, I reached over and touched the golden swallow held in the hand by the old ghost, its appearance felt quite hard, even if it was not gold, it must be some kind of hard metal, a bird carved from metal, it was hard to believe. I couldn't help but mutter, "Is this thing really flying?" Unlikely, right? ”

Wen Qingshan said with a smile: "The book says that Jin Yan can fly, it should just be an exaggerated description, so as to describe this Jin Yan as lifelike." ”

Hearing Wen Qingshan say this, I nodded and said, "That's right, this golden swallow is indeed quite exquisitely carved, and at first glance, it really looks like it's alive." ”

"And how much is this thing worth?" This guy is simply a money plague, and it seems that everything can be measured by money in his eyes.

"This golden swallow embodies the ultra-high metal processing technology of more than 2,000 years ago, I am afraid that this is the only one in the world, and it should be regarded as a priceless treasure." When Wen Qingshan said this, he suddenly changed his words, turned his head to the old ghost and asked, "Senior old ghost, do you think this golden swallow will be the key to opening this stone gate?" ”

The old ghost did not answer Wen Qingshan immediately, but stared at the Jin Yan in his hand, looked at it carefully, turned his head to look at the gossip pattern on the top of the stone pillar, frowned and muttered for a while before he spoke: "The inscription engraved on this Jin Yan is the same as the one on the stone pillar, and it is very likely that it is the object that opens the Qi Spirit Lock!" ”

Speaking of this, he tried to put the golden swallow in his hand towards the depression in the middle of the Bagua pattern.

What people didn't expect was that Jin Yan could just fit into that depression, and the two could almost be said to be seamless.

Seeing this, I immediately understood, no wonder the concave shape looked so strange, it turned out to be completely carved according to the shape of Jin Yan.

The old ghost shouted excitedly, "That's right! That's right! This thing is the same thing that opens the Qi Spirit Lock! As soon as he finished speaking, a faint green mist suddenly rose from the stone pillar.

Everyone was taken aback and hurriedly took a few steps back.

However, after waiting for a while, nothing happened, the stone pillar did not react, and the stone door did not open.

I couldn't help but wonder a little, and asked in a low voice, "Old ghost senior, why didn't there be any reaction when there was a puff of smoke?" ”

The cheap guy took me and said, "Could it be that time has passed too long, and this thing has become invalid?" ”

The old ghost stared at the golden swallow on the stone pillar with his eyes, and said without raising his head: "What's the hurry, wait!" ”

We had to stand aside and wait quietly for a while, and suddenly, there was a "click" sound from the golden swallow, although the sound was very small, but because everyone did not speak, the surroundings were extremely quiet, so everyone heard this sound very clearly.

I don't know what happened, everyone thought it was strange, I was thinking about what would happen next, but suddenly I noticed that the golden swallow's wings seemed to be slowly spreading.

I thought I was dazzled, so I hurriedly raised my hand and rubbed my eyes, and then fixed my eyes to take a closer look, and I couldn't help but be surprised, that's right! The golden swallow was indeed spreading its wings.

The fat cow man standing next to me was obviously frightened by the scene in front of him, grabbed my arm, and stammered, "Brother, this is ...... What the hell is this...... Why do you seem to be alive...... It's alive......"

"Don't be afraid, this thing should just be ......" Before I could finish my sentence, the golden swallow suddenly flapped its wings and flew into the air.

I was dumbfounded, I didn't expect this thing to come to life!

Everyone's eyes widened, staring at Jin Yan flying around in the air, one by one, dumbfounded, as if they couldn't believe what was happening in front of them.

The cheap muttered in a daze, "This ...... This priceless treasure is really different......"

Jin Yan circled three times above our heads, and suddenly I heard a loud "boom", and I hurriedly looked down, only to find that the stone door had been opened.

At this moment, the golden swallow suddenly dived and flew into the stone gate that had just been opened. Only then did the old ghost react and immediately said to everyone: "Quick! We have to hurry up and get in, or we will have to close the stone door again. ”

After saying that, he quickly stepped forward, bent down and bowed his head, and got into the stone gate. All of us did not dare to slack off, and we all followed him and entered the stone gate one by one.

Inside the stone gate was an extremely narrow corridor, half a meter wide and a meter high, and even the old ghosts, who were dwarfs, had to hunch over and walk inside, while the rest of us could basically only crawl on all fours.

Fortunately, the corridor is not very long, about four or five meters, we quickly drilled out of the corridor, came to a boxy tomb, I looked around, this tomb is not very big, about a dozen square meters, the four walls are made of bluestone bricks, in the corner of this tomb, stacked a lot of hoes, pickaxes and other things, it seems that this should have been a tool room.

Those tools were already rusty, and the color of the rust was dark brown, which looked like rust, and I couldn't help but ask with some wonder: "Isn't the Qin Dynasty still dominated by bronze?" Why do these tools seem to be made of iron? ”

Wen Qingshan bent down and picked up a rusty hoe, took it in his hand, and said: "This is not surprising, although the weapons of the Qin Dynasty are still mainly bronze, at that time, iron tools have actually begun to be widely used in agricultural production. ”

After listening to Wen Qingshan's explanation, I couldn't help but sigh: "It turns out that iron tools were first used in agriculture and then in the military. ”

Wen Qingshan smiled: "Hehe, you can also say that!" During the Qin Dynasty, bronze was a war material, and the people were not allowed to hide it privately, so the common people could only use iron tools to build agricultural tools, and in practical use, people gradually found that the physical properties of iron tools were much better than bronze, and they were easier to forge, and in the Han Dynasty, iron tools gradually replaced bronze as the main material for making weapons......"

Before Wen Qingshan finished speaking, he interrupted him on the side: "I said can you stop discussing these things first, the priceless Jin Yan is gone!" ”

Hearing him say this, I just reacted, yes, where is that golden swallow? Didn't you just fly in?

I was looking around, and suddenly there was a "boom" sound from the corridor behind me, I hurriedly turned around, bent down and bowed my head, and looked into the corridor through the searchlight on my helmet, and sure enough, as the old ghost said, the stone door had really closed by itself.

Seeing this situation, the cheap said worriedly: "It's miserable now, the door is closed, how can we get out later?" I don't think I'm going to be trapped in this. ”

"Don't worry! Later, I will naturally be able to find the mechanism to open the stone door, besides, if I am really trapped in this, it is not bad, I can be buried with Qin Shi Huang in the same mausoleum, it is a blessing that can only be cultivated in eight lifetimes! The old ghost teased, and he didn't seem to worry about getting out of here.

Wen Qingshan took the old ghost and said, "I estimate that Jin Yan is the key to opening the stone gate, as long as I find it later, I may be able to open the stone gate." ”

The old ghost nodded: "That's right! That golden swallow has an extremely special aura, presumably as long as it gets close to the stone gate, the stone gate will open on its own. ”

Hearing what they said, everyone immediately raised their heads and looked around, hoping to find the golden swallow, but they could not see it.

Of course, this tomb is not in a completely sealed state, on one of the walls of the tomb, there is a wooden door about two meters high, because it is old, the wooden door has long been dilapidated, on the door, there is a hole about the size of a basketball, since Jin Yan is not in this tomb, then it must have passed through this hole and flew away.

Everyone walked towards the wooden door, and Long Jiansheng, who was walking in the front, stretched out his hand, grabbed the edge of the wooden door, and pulled it, the wooden door seemed to be locked, and failed to pull it open.

Long Jiansheng exerted a little more strength, pulled suddenly, and with a "click" sound, he pulled off a large piece of the wooden door panel, it turned out that the wooden door had already been somewhat rotten.

Seeing this, I couldn't help but mutter, "The rusty iron and the rotten wood are all characteristics of oxidation, is there still enough oxygen in the Mausoleum of Qin Shi Huang?" ”
