After I finished dismantling the hexagrams, I couldn't help but look towards Song Dakui.

"I have said so much, can you understand me?"

Song Dakui nodded.

"Although I don't understand the meaning, I can basically understand it. The central idea is that wherever you go, I will follow you."

I smiled helplessly. "It seems that there is nothing wrong with this understanding."

According to the dismantling of the hexagrams, whenever we encounter the entrance of a cave, we should go left and move forward without looking back.

I don’t know how long it took, but there were fewer and fewer forks in front of me, and there were actually wires on the cave wall above my head.

These wires are made of yellow rubber wrapped with a copper core, which is relatively resistant to corrosion and aging. After many years, no damage can be seen on the surface.

This mine is very deep, but fortunately there is no branch road in the middle. You can always see wires on the surrounding walls, just follow the wires and keep exploring.

After about five or six minutes of walking, the road started to become difficult to walk.

There are potholes underfoot, moisture is obviously seeping into the surrounding walls, and the broken gravel road is covered with green moss and puddles.

Logically speaking, the mountains nearby are all rocky, so there shouldn't be such a lot of moisture.

"Go when you encounter water and stop when you encounter fire. It seems that we are not going wrong."

"Xiao Qin, did you smell something that was very pungent to your nose?" Suddenly Song Dakui covered his mouth and nose and coughed, and then frowned.

I arched my nose and smelled the air, and found that there was indeed a strange smell.

However, these odors are just a bit pungent, and the body does not feel any discomfort after smelling them. It should not be toxic gases.

"There seems to be a light ahead?" Suddenly Song Dakui's expression changed, he pointed to the front of the mine not far away and said with a face full of surprise.

I couldn't help but frown, and looked in the direction Song Dakui pointed. Sure enough, there were wisps of green light in the mine.

But why is this light green?

"Be careful, this light looks a bit weird." I pulled out the bamboo slip from my sleeve and carefully looked at the place where the dim light was emanating.

Song Dakui nodded slightly and took out the silver dagger from his pocket.

This is not the first time I have seen this silver dagger. I never expected that Ma Xuanyi would pass it on to Song Dakui so quickly.

It was eerily quiet in the mine, and you could clearly hear the sound of water dripping on the rocks and the sound of the two of us walking.

Click!

Suddenly I felt as if I stepped on something under my feet, and there was a crisp sound.

I quickly looked at my feet with a flashlight and saw half of a light green stick-like thing stuck in the rubble at my feet.

I quickly leaned down and pulled out the half of the green stick from the crack in the gravel.

I saw that the stick-shaped object was roughly a foot long, and there were green water droplets dripping from the bottom. It seemed that there should be more moisture in the gravel pile under my feet.

Song Dakui also came up and looked at the bones in my hand. He asked doubtfully: "What is this?"

I carefully wiped the surface of the stick-like object, and a flash of white color suddenly appeared.

This turned out to be a white bone stuck in a crack in the stone. Judging from the color and length, it should be similar to the bones of domestic animals, mostly pigs and sheep. But how could there be bones of domestic animals in this mine?

"Look, there seems to be one in front of you!" Suddenly Song Dakui pointed to the pile of rubble not far ahead and said.

I couldn't help but frown and continued searching forward.

I found that there were a lot of animal bones mixed in these rubble piles. The closer to the green light, the more animal bones there were.

In the end, the gravel on the ground was almost replaced by bones everywhere. It is roughly estimated that the number of bones in the mine is enough for thousands of domestic animals.

These animal bones are covered with moss and have been soaked with moisture for so long that it is difficult to tell the specific year. However, I think these livestock have been dead for a long time.

"How come so many livestock died here?" Song Dakui said with a surprised look on his face.

"I think the answer is right in front of me?" I frowned, looking at the green light so close at hand with a solemn look in my eyes.

Obviously, the closer you get to the place where the green light emanates, the more animal bones there are on the ground. If you want to know the answer, you have to go and find out.

I couldn't help but wonder in my heart. Could it be that all these domestic animals have been bitten by flying zombies? But this is too much!

"Go further and take a look?" I couldn't help but frown and walked forward first.

This time Song Dakui also swallowed his saliva and looked at the bones on the ground. Even anyone would feel a little trembling in his heart. After a while, he nodded firmly.

After that, the two of us groped towards the direction where the green light penetrated, and a rusty iron door appeared in our sight.

I saw a large iron door in front of me that was as tall as a person. Due to the passage of time, it was covered with moss and the surrounding frames were completely rusted.

There is a vent about half a meter in diameter on the top of the iron door, which is covered with steel bars. This faint green light is projected from this good window.

This big iron gate looks like a gate on a hydropower station or a dam. There is no lock or guard on the surface. There is something similar to an electric box next to it. This iron gate should be powered by electricity.

controlling.

"Xiao Qin, why is there a big iron gate in this mine? It doesn't look like a place where ore is mined?"

I couldn't help frowning, shaking my head and saying, "Who knew, those stupid little dwarfs often do bad things in our territory.

They said they were mining, but who knows what shameful things they were doing behind the scenes."

After opening the electrical box, there was a rotten smell immediately, and even the electric switch was covered with moss and water stains.

"It travels when it encounters water and stops when it encounters fire. Electricity is fire. Could it be that Feizhi is hiding behind this big iron door?"

After Song Dakui closed the switch, there was indeed no movement.

I knocked on the iron plate on the iron door, and there was a banging sound immediately. The iron door should be at least a foot thick, and I am afraid it cannot be opened with brute force.

"This door is rusted to death. It will definitely not open if pushed. How about we try explosives?" Song Dakui couldn't help scratching his head and asked.

"Are you crazy? This place has been soaked in water all year round, and the soil is very soft. If we really had to use explosives, maybe the door wouldn't have exploded, and the two of us would have been buried inside first."
