Everyone was taken aback by the ripples in the mercury pool for no apparent reason.

Wen Qingshan hurriedly asked the fat man, "Soldier, are you sure that something didn't fall into the pool?" ”

The fat cow stammered, "I...... I seemed to see something swimming in the water. ”

"How is this possible! It's mercury! Nothing can survive in mercury, you're dazzled! ”

Seeing that there was a broken tile on the floor beside him, he stepped forward and picked up a small brick and threw it into the pool of mercury, but the brick fell into the pool of mercury, and after touching the mercury, it immediately bounced up again, and finally floated on the surface of the mercury.

The cheap was a little surprised: "What's going on?" ”

I glared at him and said, "How did you learn physics before!?" The density of mercury is greater than that of copper and iron, and copper and iron can float on mercury, not to mention floor tiles with lower density! ”

As soon as I finished speaking, I turned my head to look at me and said, "Brother, what are you talking about!" Of course I know the tiles are going to float on the mercury, I mean what that ripple was all about! If it was a floor tile or something else that fell into the pool of mercury, it would have floated, but just now I only saw ripples, but I didn't see anything floating on the mercury, don't you think it's strange? ”

I couldn't help but be a little surprised when I heard what the cheap guy said, I didn't expect him to think so deeply this time, and it sounded very logical.

Wen Qingshan nodded and praised: "Cheap is right, this thing is indeed a little strange. ”

"What do you mean? Could it be that what the fat man said is true, what is really in this pool? ”

"It's unlikely, maybe something more dense than mercury fell into the pool......

Before Wen Qingshan's words fell, suddenly there was a ripple in the pool again, this time everyone saw it really clearly, it really looked like something was diving in the pool!

Seeing this, everyone was shocked, even the face of the experienced old ghost changed, and he said in a hurried tone: "This ghost place is not a place to stay for a long time, let's leave quickly!" ”

Everyone didn't bother to explore what was in the mercury pool, and the group quickly rushed across the arch bridge, walked across the arch bridge, and walked up another staircase, and when we walked up the stairs, a large palace appeared in front of us. The palace is almost fifteen or sixteen meters high, and there is a row of huge pillars with a diameter of nearly one meter in front of it, I counted them, there are exactly nine, and there is a dragon coiled on each giant pillar, which looks vivid, just like a real dragon.

The whole palace looks quite magnificent, but as far as the eye can see, the palace does not have a window, only a wooden arched gate about five or six meters high, tightly closed, on the left side of this gate, there is a cylindrical stone platform one meter high, the diameter of the stone platform section is about fifty centimeters, and in the center of the stone platform section, there is a round hole with a diameter of about five centimeters.

And on the right side of the gate, a weapon rack is placed, there are a lot of weapons on the weapon rack, knives, swords, spears, guns, halberds, bows, crossbows, etc., almost eighteen kinds of weapons are readily available, and there is a weapon in which the appearance of a weapon looks a little strange, this weapon is made of bronze throughout, there is a long handle, one end of the long handle is a hemispherical bowl-shaped object, at first glance, it looks like a dung scoop used to scoop the manure tank in the countryside. Of course, this can't be a dung scoop, maybe some special weapon.

Everyone didn't care too much about what this weapon was used for, and at the moment everyone had only one thought, and that was to open the door in front of them quickly! The old ghost walked forward slowly, and first pushed the door hard, but he didn't move.

He turned his attention to the stone platform on the left side of the gate, which, according to his previous experience, would never have been placed next to the gate for no reason, it must have had some purpose, and it was the mechanism that opened the gate nine times out of ten. The old ghost walked over to the stone platform and examined it carefully, and the rest of us gathered around.

However, everyone looked around the stone platform for a long time, but did not see any mystery, the stone platform was very smooth, nothing was carved on it, the old ghost tried to turn the stone platform, but the stone platform was fixed, and there was no way to turn it. Only the round hole in the cross-section of the stone platform is not known for what it is used for.

I looked into the hole with the searchlight on my helmet, and found that the inside of the hole was an inverted cone, and there was a very thin hole at the bottom of the cone. The diameter of the small hole is only a few millimeters, and it is unknown what is inside.

The cheap stared at the round hole and said, "Could it be that this is also a Qi Spirit Lock, and the object that triggers the Qi Spirit Lock is an inverted cone-shaped object?" ”

Wen Qingshan nodded and said, "I think it's possible, or let's look for it first." ”

The crowd immediately split up and searched for it.

However, after looking for a long time, they couldn't find the so-called inverted cone-shaped object, everyone was puzzled, Wen Qingshan stared at the round hole for a long time, and suddenly seemed to think of something, turned his head and said to everyone: "You say, is it possible that what triggers the Qi Spirit Lock is not a tangible thing?" ”

"Boss Wen, what do you mean by that?" I heard it a little foggy.

Wen Qingshan pointed to the inverted conical round hole and said, "If you take a closer look at this round hole, I think it's more like a funnel!" ”

"Funnel!?" Everyone was a little surprised, but after listening to what Wen Qingshan said, I took a closer look at the round hole, not to mention, it really looks like a funnel, but if this thing is really a funnel, what is it used to leak or something?

Wen Qingshan pondered for a moment, then suddenly patted his head and said, "I know!" It should be to pour mercury into this funnel! ”

"Boss Wen, how do you know?" I asked, puzzled.

"As we traveled, we saw only two ready-made liquids, one was the strong acid solution in the moat, and the other was the mercury in the pool of mercury. So, it must be one of these two liquids. ”

"So how can you be sure it's not a strong acid solution?"

Wen Qingshan didn't answer me directly, but turned around and walked to the weapon rack on the right side of the gate, and asked rhetorically, "Don't you think it's a little strange to place a weapon rack at the door of a large hall?" ”

Hearing Wen Qingshan say this, I thought about it, why put an armory rack in front of a big hall?

Wen Qingshan stepped forward and picked up the strangely shaped weapon from the weapon rack, and continued to ask me, "What do you think this is?" ”

I shook my head: "I haven't seen it, I think it must be some kind of weapon." ”

"Nope! This is not a weapon, but a scoop for scooping mercury. ”

Hearing Wen Qingshan say this, I couldn't help but be stunned, no wonder I think this thing looks a bit like a dung scoop used to scoop a manure pit in the countryside, it turns out to be a scoop.

Wen Qingshan continued: "This thing is made of bronze, and the strong acid solution in the moat will corrode the bronze, so it is unlikely that this thing is used to scoop those strong acid solutions, and it is more likely to be used to scoop mercury!" Speaking of this, Wen Qingshan turned his head and asked the old ghost: "Old ghost senior, in my humble opinion, do you think there is some truth?" ”

The old ghost neither agreed nor objected to Wen Qingshan's analysis, but said lightly: "Since you think so, then try it!" ”

Wen Qingshan handed me the bronze scoop in his hand: "Shi Yu, go and scoop a spoonful of mercury." ”

I nodded, took the scoop, and walked towards the pool of mercury.

I walked to the mercury pool, put the scoop into the pool, scooped up a full scoop of mercury, turned around and was about to leave, when suddenly there was a "bang" sound from the mercury pool.

I turned my head abruptly, and saw that the mercury in the pool was shaking violently, and there was a ripple that had been scratched, as if something had just crossed the surface of the mercury.

I couldn't help but feel nervous, it seems that there really is something in the pool! What kind of monster could survive in mercury!?

Though I was scared, I was anxious to find out what was going on, so I took a deep breath and boldly plunged the scoop into the pool of mercury again, stirring it in it. Then he scooped up a scoop of mercury and quickly took two steps back.

I stood by the pool and waited for a while, but nothing came out this time.

I was wondering, Wen Qingshan shouted, "Shi Yu, what's wrong?" ”

"It's nothing, I'll come over here."

I turned around and was about to leave, when suddenly there was a "bang" sound behind me again, I hurriedly turned my head to look, and was suddenly startled, something jumped out of the pool of mercury, extremely fast, reflecting a dazzling silver light under the illumination of the searchlight, at first glance it looked like a fish!

The thing jumped more than two meters high and hovered in mid-air, and I couldn't help but be surprised that it was a dragon that jumped out of the pool of mercury!

The dragon was silvery-white, looking as if it had been made of metal, and strangely enough, it had jumped out of a pool of mercury without a drop of mercury on it.

The appearance of the silver dragon was different from the dragon I had seen in the illusion, it was much smaller, about a meter long, the diameter of the thickest part of the body was only a dozen centimeters, and the horns on the head were not forked. It feels like it's just a baby dragon. But even so, it still shocked me so much that I couldn't do it, and everyone else was shocked, and the fat man couldn't help but let out a loud scream.

The silver dragon circled above my head, its eyes fixed on me, its eyes shining fiercely, as if it were about to pounce on me at any moment.

Although I am a descendant of the dragon vein, and I claim to have the blood of a dragon flowing in my body, it is the first time I have faced a real dragon, and I don't know whether it is friend or foe, I am so nervous that I dare not be careless, I hurriedly threw the bronze scoop in my hand to the ground, and quickly reached out to my waist and pulled out the dragon tooth and held it tightly in my hand.
