The roaring gunshots continued one after another, and large balls of energy bombarded the ice, and the ice and snow were vaporized before they could melt under the high temperature, turning into a cloud of empty mist and floating in the air. After more than 20 shots in a row, the solid ice surface finally could no longer hold on, and after the last energy bomb collided with the ice, it rushed directly under the ice, and flew all the way into the darkness along the passage behind the ice.

"Whew, it's tough, but I'm finally lucky to have a place to spend the night. Freya verified her suspicions, exhaled in a good mood, and leaned down at the hole she had opened and looked in. Obviously, the entrance to the cave is not natural, and someone has dug a tunnel diagonally down from the foot of the iceberg by some unknown method. The tunnel was wide enough for a normal human to stand and move forward, and even the edges of the tunnel were neatly groomed, looking less like a shelter being dug at random, but rather like a well-groomed room. However, it seems that many years have passed since the excavation of the tunnel, and the entrance of the tunnel is once again covered by solid ice, completely burying the secret of the tunnel's existence under the ice, if it were not for Freya's careful observation and keen attention to the slight difference in the color of the ice, I am afraid that in a few years, this tunnel will never have a chance to appear in the sun again.

"I don't know who you are, but thank you anyway. Freya thanked the forerunners who had excavated the tunnel, and then stuck her head inside the tunnel. With the help of the cold wind on the ice field, the foul air in the tunnel was quickly replaced, and it was no longer too abnormal to breathe. It was already completely dark, and the girl thought about it, took out the small lantern she had with her for emergencies, charged it with a hedron and lit it, and lit it at the entrance of the cave. Although the tunnel is not deep, it is also about ten meters long, and the small lantern does not allow her to see the situation inside, so she has no choice. Freya could only hang the lantern on her waist and limp into the tunnel with the crystal gun in both hands.

There is a drop of several tens of centimeters between the entrance and the tunnel floor, which is probably caused by the gradual rise of the ice over the years. The hesitant ground is made up of pure ice. It's so slippery that it's almost impossible to stand on it, but luckily the person standing here is Freya, who can use the small device on her shoes to stabilize her footsteps, if you change to someone else in the party. I'm afraid that if you step on it, you will slide down the slightly inclined tunnel all the way down to the deepest part of the cave.

After taking a few steps, Freya could hear no sound other than the echo of her footsteps and her own heavy panting, and she did not notice anything unusual. The girl breathed a sigh of relief, and instead held the crystal energy gun in one hand, took off the lantern in her left hand, and held it to look to the sides. Just like what was found outside the cave before, the ice walls on both sides were neatly groomed, and the diggers looked like boring people. The pursuit of perfection is so neat that even the caves that are dug out by hand are neat to this extent.

"Looks like it's safe here, there's nothing in there. "Walking further along the passage, it didn't take long for you to see the blurred walls and reflected light from the end of the cavern, as if you had gone to the deepest point. Freya sighed, just relaxed, the corners of her eyes suddenly jumped, and she whispered in surprise: "No, that's not the reflection of the wall, that's." That's an igloo?"

It's no wonder that Freya was surprised that the appearance of the igloo was really unexpected. At the end of the tunnel was excavated a wide circular cavity, and in the center of the cavity stood an ice hut, for Freya. It was like a gift from the gods, and it would have been perfect if there had been hot bread on the table in the hut, and of course, if you think about it, it would be a dream. But. Even if you don't have steaming fluffy bread, it is the favor of the gods to find such a shelter on the hellish ice field.

"Hope not to meet the owner of the house inside. Freya was in a good mood to find something else, and after a careful search and no danger was found, Freya said to herself half-jokingly: "Whether it is dead or alive, it is best not to encounter it." ”

Walking through the doorless door into the igloo, Freya's hanging heart finally let go, there were no living creatures in the igloo, neither dead nor alive. The ground of the igloo and the floor of the cave are not horizontal, the inside is about one and a half meters lower than the outside, and as soon as you enter the door, you need to go through several layers of downward stairs to enter the main space of the igloo. The space of the igloo is not too large, and it can only accommodate four people to move around normally. In one corner of the room were four beds, three long and one short, covered with thick animal skins, and a large amount of animal hair under the animal skins, making the whole bed soft and warm. Although it has passed the baptism of time, due to the effect of low temperature and confined space, the animal skin still retains elasticity and feels soft and smooth to the touch.

On the other side of the room, there was a set of tables and chairs made of ice, also covered with a layer of animal skin, and they were cleanly wiped and not dusty at all, as if they were freshly made. In addition, there are no other special items in the igloo, and many places have traces of placing items, but now they have also become empty, and it is estimated that the owner of the igloo took away all the items that could be taken away when he left, leaving only the simplest furniture.

"It's so nice here, it's like a dream. However, I always feel that this way of building a house is somewhat familiar, and it seems that it has been used in the snow before. Freya examined one of the beds carefully, and there was no danger in the slightest, and then she sat down on the soft hides, relaxed her aching legs, and looked around the room, hoping for some clues. After only a few seconds, the girl patted her forehead and stood up, and smiled self-deprecatingly, for she found that there was also a bag of animal skins on the table, which she had not noticed when she had just come in because of the proximity of color.

Opening the animal skin bag, there are several pieces of parchment with words written inside, and Juanxiu's notes make people feel very comfortable at a glance.

"To the unknown latecomers. The words on the parchment could be seen clearly under the lantern: "Do you like this gift? This was built during our twenty-five day trip to the icefield, and the fool and I both thought that this hut might be of help to those who came after us, so we didn't tear it down when we left, I hope we are right, it really helps you." ”

"I just loved it. Knowing that the person who left the letter would not hear it, Freya still said gratefully: "If I can survive, at least half of the reason for this igloo, thank you so much, unknown forerunner." (To be continued.) )
