Shui Xiaoxing and Su Xin were in the cave, and they didn't find the disabled second child, but they saw something they had never seen before, it was an extremely thick ice wall, and at the same time, the ice wall also blocked the way of the two, but there was a huge ice coffin behind the ice wall, and in that ice coffin, Shui Xiaoxing and Su Xin seemed to be able to see a person lying down!

"Hyosung! That...... It seems to be people there! Su Xin exclaimed.

"The two layers of ice are separated, it doesn't look very clear, Su Xin, can you tell if it's a man or a woman lying in the ice coffin?" Shui Xiaoxing couldn't help but ask.

Su Xin was really hard to see, she shook her head and said, "I can't see clearly, but Hyosung, how can we enter the ice room?" ”

"Ice room?" Shui Hyosung muttered to himself, the word ice room appeared in Shui Hyosung's mind for the first time, and Su Xin said, "Yes Hyosung, it's the ice room!" Haven't you heard of it? When I was very young, I read about the ice house in a book, well...... To put it simply, it is a burial method in ancient times. ”

"Oh! I see," Shui Hyosung nodded, but Shui Hyosung was also thinking about how to enter, if there were sappers at hand, maybe it would be possible to cut into the ice, but the ice here is indeed very strange, and the ice wall on the front of it does look man-made, not natural, so Su Xin asked, "Hyosung, who did you say built the ice wall here?" ”

"I can't imagine the wisdom of the ancients, but it doesn't seem like a single person can build such a huge project," Mr. Shui said.

According to common sense, this is true, but Shui Xiaoxing's guess is the opposite of the truth, the ice wall here is indeed built by one person, but if Shui Xiaoxing and Su Xin want to know who that person is? They have to break through the ice and enter the ice chamber to find the answer in the ice chamber.

Speaking of ice walls, Shui Xiaoxing and Su Xin both knew in their hearts, the hardness of ice was extremely strong, even a small piece of ice thorn was enough to kill a person, let alone a two-meter-thick ice wall? It seems that if Shui Xiaoxing and Su Xin want to pass through the ice wall, they must go back to call Lin Yao and the others, at least go back to retrieve the sapper shovel.

However, to Shui Hyosung's surprise, Shui Hyosung picked up a relatively sharp rock on the ground very casually, and he wanted to use the foot of the rock to cut the ice, but when Shui Hyosung grabbed the rock and slammed it into the ice wall, the corner of the rock shattered with the powerful impact, but when he wiped the dirt remaining on the ice wall with his hand, the ice wall was intact.

"What a hard wall of ice! Looks like I'm going to have to give it a try with a sapper shovel! Shui Xiaoxing couldn't help but say.

However, Su Xin shook her head, she didn't agree with Shui Xiaoxing very much, and listened to him say: "I'm afraid it won't work, although the stiffness of the sapper shovel is very strong, but Hyosung you have to know, this is not an ice wall is not weak, this is like the sharpest encounter with the strongest shield, the consequences are unimaginable, I am afraid that both sides will lose." ”

Shui Xiaoxing's mind was full of sapper shovels, but the only thoughts were refuted by Su Xin, so did Su Xin have a better way? Shui Xiaoxing asked Su Xin, and she said, "It's really hard for me to come up with a better way, so it seems that I have to ......."

"It's a good idea, but with a two-meter-thick wall, how long will it take!" Shui Xiaoxing already knew Su Xin's intention to use fire, saying that ice is made of water condensation, and negotiating the use of temperature to melt ice is indeed the best method, and fire is indeed the best tool.

Listen to Shui Xiaoxing said: "It's better to wait for me here, Sister Su Xin, I'll quickly go out to find some wood fire, and then let's make more torches, and then we just need to use torches to bake a hole, the hole doesn't have to be too big, as long as people can turn in." ”

Su Xin agreed with Shui Hyosung's approach, and said, "Then I'll wait here, Hyosung, you go and come back quickly, don't worry me for too long!" ”

Shui Xiaoxing nodded and flashed out, saying that there were a lot of dry branches on the hill, but this guy actually dragged a dead tree and walked back, Su Xin was extremely surprised at that time, but he never thought that Hyosung would have so much physical strength after he was poisoned, and soon the torch ignited one end of the dead tree, saying that the fire was still quite big, the ice did begin to melt gradually, and a drop of water also slipped down with the ice, and soon the ground began to become damp, lest the dead trees be wet and flame retardant by the wet ground, and listen to Shui Xiaoxing say: "Sister Su Xin, come and sit on my side, the terrain on your side is too low, I see that the water is flowing under your feet, don't wet your shoes and catch a cold." ”

Saying that the ground on Su Xin's side was indeed wet with water, it was time to change to a better terrain, she came to Shui Xiaoxing's side, and at the same time was roasting the fire, at this time the bodies of the two of them warmed up, it is said that the speed of using fire to melt ice is not slow, and soon grooves gradually appeared on the ice wall, but the heat of the fire is rising upward, and it cannot transmit heat horizontally, which requires convection, so that the heat can be transmitted in the groove, and the ice wall two meters behind will be melted through in the shortest time.

Simple I know the laws of physics, Shui Xiaoxing and Su Xin, but the conditions here are limited, and it is not like what you want in the laboratory, as long as Shui Xiaoxing makes a wooden wall with dead branches, if the wooden wall is not ignited, in short, it can still resist the spread of some heat.

But Shui Xiaoxing and Su Xin only care about melting ice, but forget the time, in the cave is not better than outside the cave, there is no light source here, and people will soon lose the concept of time, but some people will also know that people in the dark prefer to snuggle up to each other, Shui Xiaoxing and Su Xin are no exception, the two are chatting about the sky, while working, and from time to time they have to check the situation around them, after all, this is a mysterious cave, if you don't do it, you will write something inexplicable!

But where did the second child go? Didn't he enter the cave? So why did the blood drip to the door of the cave and stop abruptly? A lot of questions appeared in the minds of Shui Xiaoxing and Su Xin, and now that they can't find the second child, they can't prove Su Xin's innocence.

However, there is still a lot of history about this cave, so we have to start from this hill, the hills here used to be very famous, from the railway station to all directions, a total of four neighboring hills, the southeast and northwest are divided into four adjacent hills, the height of the hills is about the same, and behind the four hills in the southeast, southwest, northwest, and northeast, there are still four hills in the southeast corner, southwest corner, northwest corner, and northeast corner.

The size of these four hills is actually not much larger than the four hills in the south, east and west, if you look down and look down at these hills, it is like a gossip, so the eight mountains were called Baigua Mountain by the ancients.

As the saying goes, gossip is ever-changing, and the ancients have taken advantage of the geographical advantages here, fought a lot of victories, from the deployment of troops and layout, from the feng shui trend and many other factors, can have thousands of evolutions and changes, so it was named Baigua Mountain, at that time it was also the place where the enemy was terrified.

But among the eight hills of Baigua Mountain, each has a cave, back then, these eight caves, in fact, were built in a formation, and its purpose was of course to hide their own situation, in the case of a surprise attack on it, so these eight caves are built in extremely hidden places, today if Shui Xiaoxing and Su Xin are not following this blood drop, I am afraid they will not be able to find the cave in the hill, in fact, it is the ghost of the hundred trigrams hidden by Feng Shui.

Once in the kingdom of the king, there was not only the saying of Baigua Mountain, but also the name of the kingdom, called Bamenshang, which essentially means that there are eight caves in the mountain.

The cave where Shui Xiaoxing and Su Xin are located is the westernmost cave, the ancients once said that the east rises and the west sets, which is according to the sunrise and sunset, and the meaning of the east and the west is completely different, saying that the east is auspicious, and the west is the meaning of returning, just like the purple gas comes from the east, and the crane goes west, so the meaning of the west is indeed not very good, but strange things happened in the west, saying that there is a coffin in the west, but there is a meaning of driving the crane to the west, in fact, it is not, this unbelievable thing still has to start from the day city......

The name of the city lord in the day city is Lan Lan, after Su Xin entered the return gate, she can be 100% sure that Lan Lan is the city lord of the day city, and at the same time, the day city is the witch city, so it can be said that Lan Lan is also the city lord of the witch city, which is understandable.

But Su Xin, Shui Xiaoxing and others didn't know that Lan Lan City Lord was a twin, and she even had a twin sister who looked almost exactly like herself, her sister was called Lan Qing, which was a household name, that is, the night Qing Lan entered, the first autumn white dew group, and the names of the two sisters came from this, so the sister's name was Lan Qing, and the sister's name was Lan Lan.

However, the personality of my sister is completely different from that of my sister, my sister never shows her face, and she rarely shows up, but she is the master who does not leave the gate, so even the people in the day city have never even seen the appearance of her sister Lan Qing, but the person people often see is Lan Lan, and Lan Qing and Lan Lan rarely appear at the same time, most people know that the original city lord does have two daughters, but they never know what that daughter looks like.

In fact, this is all the rules set by the original city lord, that is, Lan Qing and Lan Lan's mother, if her sister Lan Qing becomes the city lord in the future, then Lan Lan will be hidden in the snow, in fact, it is all for the last ray of life in the city of Day, and the two can't tell who is the sister or the sister of the city lord, so they can't help but have double insurance.

In fact, his mother will indeed treat one of the two sisters unequally, but the two sisters also know their mother's intentions, this is their mother's hard work, of course they don't want their mother's hard work to be ruined in their own hands, so the sister is willing to be hidden, and let the younger sister become the lord of the city of Day, but the word of mouth of the city only knows that it is the sister who became the lord of the city, and as for the sister, it is said that she is seriously ill, so she is not allowed to see anyone.
