I looked in the direction of his finger, and suddenly found that the road we had walked before was a little different, I always felt weird, but I couldn't tell where the fault was, I always felt that the road I had walked and then looked back a little strange, I always felt that I had not walked this road before, but the fluorite lanterns hanging high on both sides of the road were not adulterated there, and it was obvious that we had illuminated it with a flashlight.

After watching it for a long time, I didn't see a reason, so I asked Wang Ying again, "What?" I don't see anything wrong. ”

Wang Ying glanced back and said, "Look at the road surface, it was very smooth when I came before, like a mirror, and now you look again, the road we haven't walked in front of us is still as smooth as new, and the road we have walked on has been slightly dented, and the angle of the road surface has also changed." ”

After Wang Ying said this, I looked back again, and found that it was indeed just like he said, the road surface began to have some slight depressions, not only that, the road surface seems to have a slope, such a long road, can see the slope with the naked eye, then I can't wait to see it, now where we are, the road surface is only slightly inclined, if you don't look carefully, you can't find it at all, but the other end of the road, must have been raised very high, want to go back, it's almost impossible.

"How so?" I hurriedly asked Wang Ying.

He shook his head and didn't say anything, just sighed and motioned for us to move on.

For the next period of time, a group of five of us wandered around the ghost town, this silent and silent world was testing our nerves every second, at the beginning of the period, we chatted and talked from time to time, so as not to let ourselves fall into absolute silence, but after a long time, we didn't have so many topics, and the silent and dark environment shrouded us, making people feel extremely depressed.

After wandering around this ghost town for about seven or eight hours, there was still nothing suspicious, except for the houses and other buildings, and finally, we felt too tired, so we decided to take a rest in place, removed a lot of wood from the beams of a private house, and built a bonfire on the spot, and each took out food and water to replenish our strength.

Looking at the constantly burning bonfire, Huzi sighed and said, "Damn, are we here to fight, or are we here to travel?" I've been wandering around this hellish place for so long, and I haven't found anything at all, so if I continue to consume it like this, when will it be a head? As he spoke, Huzi sighed.

Listening to Huzi's complaints, we didn't speak, because we didn't know how big this ghost town was, originally I thought it was a mechanism like the Ecstasy Dao, so we kept going around in circles in an area, but I quickly denied this idea, if it was really the Ecstasy Dao, it should be a repeat of the scene, every part of this ghost town is almost different, it can't be replicated at all, it is obvious that this ghost town is very huge, and it is by no means a day or two to get out, the food and supplies we bring now, It will only last five or six days at most, not to mention how long it will take to go down to the main tomb, this ghost town alone, we will have to delay at least two days, and I don't know if we can find the real passage to the main tomb, maybe we didn't encounter any mechanism, but starved to death in this ghost town first.

While thinking, I had already finished eating the food in my hand, drank a saliva and stood up, and looked around, although this ghost town is huge, but fortunately, there is no poisonous insect and giant snake and the like, but it can be regarded as safe, we set up a tent in place to prepare to rest, this time the seventh master did not arrange for anyone to stand guard, in this silent world, standing guard has lost its meaning.

I set up my tent and went in, and soon fell into a deep sleep, not to mention, this ghost town is a good place to sleep, this sleep is absolutely free of noise, let alone day and night, and sleep very sweetly.

In my sleep, I felt that my body was getting hotter and hotter, and then I couldn't fall asleep with a hot toss, a wipe of my back, all sweat, and the sleeping bag was wet, and I quickly got up, my heart tightened suddenly, and I secretly screamed that it was not good, this ghost town is surrounded by glaciers, although the temperature inside the ghost town is higher than the outside, but it is never so high that it makes people sweat, where does this inexplicable feeling of heat come from? Could it be that the bonfire we built before was not completely extinguished, and the tent was ignited?

Thinking of this, I hurriedly looked up, but I didn't care, only to see the fire outside the tent, so frightened that I hurriedly shouted, "Not good!" It's on fire, hurry up! After shouting, I hurriedly rushed outside the tent, only to see that the seventh master had already come out of the tent, but I was the last one to get out of the tent.

I took two steps forward and asked, "Seventh Master, what's the situation, how is the temperature ...... here" I was halfway through my words, and I was shocked by the scene in front of me, only to see that not far in front of us, under the square bricks on the ground, the huge fire was like a fire dragon, almost illuminating the entire ghost town, this underground fireworks I have seen for the first time, it was under our feet! The fire burned very much, I saw clearly, it turned out that the ground under our feet was all made of a kind of transparent jade, when there was no light, the jade ground under our feet was inky black, and it didn't look much different from the bluestone road, but as soon as the underground fireworks were lit, the entire ghost city street was like transparent glass, reflecting the fire light below, and our faces were red.

"This fire...... How did this fire come out of the ground? Huzi's mouth opened in surprise, and he held back this sentence for a long time.

This is the seventh master and Wang Ying said at the same time, "Combustible ice, there is a large amount of combustible ice stored underneath!" ”

This combustible ice is a very peculiar energy substance, is a natural gas hydrate, generally distributed in deep-sea sediments or perpetual moving soil on land, by natural gas and water under high pressure and low temperature conditions formed similar to ice-like crystalline substance, its appearance is like ice, and can be burned in case of fire, the main component is methane, since the 60s of the last century, the United States, Japan, Germany, China, South Korea and other countries have formulated a research plan for the exploration and development of combustible ice, it is said that the concentration of this combustible ice is very high, If it is converted into gasoline and put into the car, only a small piece is needed, which can make the car drive for more than half a year, and it can also be said to be a new type of fuel, I didn't expect to meet it here, and look at the scale of the burning, the temperature of the underground fireworks, I am afraid that the storage is still very huge.

"I'm rubbing, the ground temperature is getting higher and higher, what should I do?" Huzi exclaimed, I looked down, and found that the soles of my shoes had begun to emit white smoke, the temperature of the surface of the earth should reach at least 100 degrees of high temperature, at this time, if anyone accidentally falls, it will definitely be scalded a piece of meat, according to this, within ten minutes, our soles will have to be melted, and then we will be in trouble!

"Up, on the roof, quick!" I was in a hurry, and quickly pointed to the house on the side of the street, although this house is not too high, but it is finally far away from the ground, the heat conduction will not be so fast, and the temperature must be much lower than the ground.

Huzi listened to my shout, the first to move, because he is 1.9 meters tall, climbing this kind of house is simply pediatrics, a brisk walk towards the nearest house to himself rushed over, just put his hands on the wall, suddenly screamed "Ah... Lao Bai, I'm drafting uncle, you pit Lao Tzu! I saw a puff of white smoke coming out of the palms of his hands, and it seemed that the temperature of the walls of this house was not low.

At this moment, Wang Ying moved, only to see that his five fingers were like hooks, and each fingertip was carrying a metal object, and the whole person used the metal object on the fingertip to grab the wall two or three times and climbed onto the roof, and then threw out a piece of climbing rope downward, "Hurry up, this rope can't last long!" ”

Fortunately, this house is not high, I pulled the mountaineering rope with one hand, kicked on the wall with my foot two or three times, and was pulled by Wang Ying, dragged my whole person to the roof, came to the roof, and instantly hurried much better, the temperature here is much lower than inside, standing on the roof and looking down, I saw that the entire ground below was red by the fireworks, and the air on the ground began to distort.

Just when I was still shocked by the scene under the house, I was suddenly tapped on the shoulder, and when I turned my head to look, I saw the seventh master and Wang Ying pointing to the front and said, "I found it, it turned out to be here!" I heard them say this, and hurriedly looked forward, because of the underground fireworks, the whole ghost town was bright, I looked around, only to see that the houses in this ghost town were built very exquisitely, the height difference was very regular, and I looked carefully at the past, between the houses and the houses, a road was formed on the roof of the house.

"Damn it, do you mean that the passage into the main burial chamber is on the roof?" Huzi scolded and looked at it carefully.

At this time, I already have the answer in my heart, I'm afraid it's really the same as Huzi said, the Yongdao that enters the main tomb may really be on this roof, if it is not for the underground fireworks, so that the whole ghost city becomes bright, I am afraid it is difficult to find this very inconspicuous road on the roof, only with the limited lighting tools in our hands can never be seen, such a secret design, if it is not the road to the main tomb, it is too much to say.

After looking at it for a while, the seventh master smiled slightly, and said, "There is nowhere to find the iron shoes, and it takes no effort to get it!" The entrance to the corridor is definitely here! It's also an eyesore, the underground fireworks that only burn once in two or three years happened to be bumped into by us, otherwise we really can't find this way, and then we can only be trapped in this ghost town! As soon as the words fell, the seventh master waved his hand at us, and walked forward first, I didn't dare to hesitate, and hurriedly followed.
