"I can't change my appearance, but it's nice to be able to change my clothes. Catherine grabbed her cloak and raised it.

"In the spirit world and even in the ultimate realm, anything is possible. "The surprise of the Ice Bear Abyss was only for a short moment.

A loud tremor came from above the cavern, and both Catherine and the Ice Bear Abyss looked up in unison. Although nothing could be seen from the dark roof of the cave, it was as if a giant was walking across the ground above them.

As the tremors faded away, the two of them staggered past the giants of Gear City.

The black-fronted rat's instinct found a fork in the road, and Catherine and the Ice Bear Abyss stood at the fork in the road to discuss. According to Catherine, the underground caverns crisscross certain sections and lead in different directions. If you go in the wrong direction, you may be trapped underground, and it will be too late to reach Gear City in three days to complete the transformation.

"I have a way of sifting through forks in the road. "There is more than one fork in the road, and there will only be more and more to come." We engrave a number mark at each fork, and the farther we go, the number increases in turn, so that we can record the fork we have walked, and we will not get lost even after walking back. ”

Ice Bear Abyss took out his life chess piece and said, "I'll record the route I've traveled and see if I can draw a map of the cave." With a map, you may be able to deduce the route you will be heading behind. ”

Catherine carved the number one on the wall of the fork in the road, and the two entered the fork in the road on the left. After walking for less than ten minutes, the black-fronted rat instinctively found a second fork in the road. At the fork in the road, Catherine carved the number eleven and continued to choose the fork in the road on the left. When she reached the third fork, Catherine carved the number one hundred and eleven and chose the fork on the left again.

The fork in the left was a dead end, and after walking for half an hour, the two retreated to the 111th fork, and Catherine carved a dead end mark on the left intersection and entered the fork on the right. This time in the fork on the right they came across a fourth fork, and Catherine carved one thousand one hundred and eleven.

Catherine carved a number mark at each intersection using a peculiar notation, and she would always go to the left until she came back to a dead end, then she would enter the right fork.

The Ice Bear Abyss pair was very interested in the set of marking methods, and they paid a lot of attention along the way. Of course, his life chess piece was not idle, outlining the route he had traveled with red chess pieces, and even marking the number mark carved by Catherine on the fork in the road.

After walking for most of the day, the two encountered a difficult point for the first time. There was a fork in the road that actually went back to a fork in the road they had walked, and judging from the number marks of the fork, it was the right fork in the road that the two had not had time to explore. However, because of the record of the chess of life, an irregular circular route outlined by a red chess piece is undoubtedly revealed.

Catherine and the Ice Bear Abyss studied it for a moment, then turned back from the fork in the road on the right, exploring a new direction at the previous fork.

As the two of them went deeper and deeper into the underground cavern, new difficulties arose, and four and five forks began to appear on the fork in the road. However, this did not bother Catherine, who adjusted the number notation, and the Ice Bear Abyss also recorded the map more and more carefully.

In the boring exploration and recording, the map of the underground cave on the chessboard of life gradually became detailed, and a complex route map like a spider web was presented in front of the two.

Nearly a full day passed, and both Catherine and the Ice Bear Abyss were exhausted, and they had to find a place to repair. While resting, they did not forget to study the map of the underground caves.

Both Catherine and Ice Bear Abyss are experienced adventurers, and they can deduce the general trend of the entire cave just by analyzing the layout of the underground cave.

At present, it seems that about one-third or one-quarter of the underground cave has been discovered, and further on, it is probably close to the core area of the cave. Adventurers agree that the core areas of mysterious and strange terrain often harbor dangerous or untold secrets.

It was a little strange in itself that the two of them had been walking in the underground caverns for so long, and had not encountered any other living creatures here. When they climbed down from the machine wall, they also encountered a lot of robot puppet life along the way, and the various parts and wreckage in the parts desert also indirectly indicated that this world should be full of machine puppets. So after entering the underground cave, the two of them have always been careful to guard against unknown dangers. But the cave is actually very clean, not to mention that the robot golems never appear, not even a single metal grass.

Catherine studied the composition of underground caverns, whose walls were formed by the cooling of the remains of parts mixed with molten steel. However, unlike the abyssal cave made by Hisuro, the walls of the cave here have been baptized by the years and have a unique sense of obsolescence of scrap copper and rotten iron.

The Black Shadow told the two of them that they would go to Gear City within three days and find the old wrench in Screw Alley to transform their bodies. Now that half of the time has passed, we have to speed it up.

The two agreed not to explore the remaining uncharted territory in a systematic manner, but to go directly to the heart of the underground cavern.

The Ice Bear Abyss simulates several possible routes on the chessboard of the chess piece of life, outlining them with yellow chess pieces. Catherine followed suit, and finally they chose a direction to set off.

The black-fronted rat's instinct is still the main force to open the way, and having this guy in front of him makes the two of them feel a lot more at ease. Walking on the road, the Ice Bear Abyss suddenly asked Catherine: "Have you thought about what will happen if we don't find an old wrench to transform our body after three days?"

"The worst outcome is the death of the soul. Catherine shook her head, "Could it be worse?"

"I don't know. The Ice Bear Abyss paused and said, "For us barbarians, the soul does not die, and the death of the body means that the soul can go to the ancestors. One of the purposes of my quest to explore the Ultimate Realm is to find the place where the ancestors were. ”

"You mean, your ancestors are in the Ultimate Realm?"

"Maybe. "The longer you live, the more curious you will become about this world." I've read a lot of books written by you human warlocks, and the explanations of the gods and the world have been eye-opening. I said I'd ask you for help when I go out, you remember. ”

"You don't want me to help you find your ancestors, do you?" said Catherine, surprised, then smiling. She didn't believe that the Sacred Mountain Shaman would leave the matter of the entire barbarian race to herself. There is no need to think about it, this kind of thing involves the secrets of the barbarian ancestors, and they will never let themselves know easily.

"If you have enough power in the future, it may not be. The Ice Bear Abyss actually nodded solemnly, "Of course, this is all in the future." But what I'm going to ask you about is also related to finding someone. ”
