Catherine instinctively sensed a blazing heat through the black-fronted rat, as if a fire was raging ahead.

After a brief discussion with the Ice Bear Abyss, the two decided to let the black-fronted rat instinctively stay where they were, waiting for them to come and inspect it for themselves.

As Catherine had predicted, before she had fully reached the place where the black-fronted rat instinctively was, a faint glow of fire came from the cave, and waves of heat poured in from the depths of the cave.

Catherine and the Ice Bear Abyss cautiously walked forward, the width of the cavern's passage gradually widening, and the firelight grew brighter and brighter. The black-fronted rat instinctively waited quietly by the side of the passage, and in front of it was a vast area crisscrossed by streams of molten steel. Fires and heat waves come from these streams.

The two of them walked over to the black-fronted rat instinctively and looked out at the vast area together. I saw that the molten steel streams were wide and narrow, the wide ones were no more than the length of two palms, and the narrow ones were the thickness of the little fingers. All streams have twists and turns, but they all point in the same general direction. There are plenty of places to stay between streams and streams, and with the help of these footholds, you can follow the molten steel stream.

"It's probably similar to an underground river. Catherine looked at it for a moment and said, "The tributaries of the underground river usually converge into a single main channel, and it is very likely that the main stream will be connected to the surface river. If we're lucky, we'll just walk along the mainstream and get to the ground. ”

"But these could also be magma rivers of the underworld. The Ice Bear Abyss was not so optimistic, and he put forward his own idea, "We will go in the direction of the flow, and we may go deeper and deeper into the core." ”

"But whether it's getting to the ground, or going to the core, we don't have any other choice. Catherine sighed.

"There really is no choice. Ice Bear Abyss nodded.

Catherine re-restrained the black-fronted rat's instinct to swallow into its stomach, and in such a wide area, the black-fronted rat's instinct was no longer needed to find its way.

The two of them searched for a place to land between the streams, and walked forward little by little. As the distance traveled, the streams began to merge and converge, eventually forming a small stream of molten steel more than two meters wide.

Catherine and the Ice Bear Abyss each kept moving at the same speed along the banks of the molten steel stream, keeping an eye on their surroundings.

After some distance on, there was a commotion in the distance, like the sound of talking, like the chirping of animals, perhaps a mixture of the two. If you just listen to the sound, you will think that there is a market ahead.

Catherine and the Ice Bear Abyss glanced at each other, and there was a hint of alarm in their eyes. Suddenly, Catherine saw something floating up and down in the molten steel river beside her.

The female mage winked at the Kinabalu shaman, and together they focused their attention on the molten steel river.

It was an incomplete animal limb that appeared and disappeared in molten steel. The two men followed the animal body forward. Soon, they discovered that the animal's limbs became more complete with each sinking and floating in the molten steel.

It didn't take long for the limb to turn into a bull-headed machine puppet. The bull-headed puppet lies peacefully in the molten steel, slowly moving forward with the flow of molten steel. It didn't float in the molten steel, it just floated quietly.

Catherine stared at the bull-headed puppet and noticed that the golem's eyes were reddening a little.

"Look ahead. "The Ice Bear Abyss reminds you across the river.

Catherine looked up, and the stream of molten steel seemed to be running to an end. A cliff appeared there, and the two walked to the edge of the cliff and watched the bull-headed puppet cascade down the cliff formed by the steel river. It turned out that the sound I heard earlier came from under the waterfall.

Below the cliff is a vast pool of molten steel. The cliff where Catherine and the others were located was just one of several cliffs that surrounded the deep pool of steel. As far as the eye can see, the cliffs in the distance can only be faintly visible, and one or several waterfalls flow down from each cliff, pouring molten steel into the deep pool of molten steel.

However, the most eye-catching thing is not the waterfalls, but the various machine puppets that rise and fall in the deep pools of molten steel. They all flow into the deep pools of molten steel with various waterfalls, and they come in different shapes. The bull-headed golem is just the most common type, but there are also larger humanoid golems, small bird-shaped golems, and even snail golems that resemble small floating islands.

The robot golems in the molten steel have all awakened, and they chirp from time to time, merging with the sound of waterfalls everywhere.

Standing on the edge of the cliff, the two of them could feel the huge heat emitted from the deep pool of molten steel, making it difficult to breathe. Catherine observed for a moment and said, "Those robot puppets are drifting towards the center of the deep pool, we should also go there to have a look, maybe the way out is in the middle of the pool." ”

"But something resembling a ferry must be found," said the Ice Bear Abyss. ”

"The snail has floated over, enough for us to settle down. Catherine pointed to the snail puppet that looked like a small floating island.

The two waited on the edge of the cliff for a moment, then jumped down and landed on the back of the robot snail. Compared to the robotic puppet snail that resembles a small floating island, Catherine and the Ice Bear Abyss are like two pebbles falling on it.

After patrolling around the snail's back shell, Catherine and the Ice Bear Abyss found no potential danger. They found a place with a good view, and sat there as the robot puppet snail drifted towards the center of the molten steel pool.

In the center of the molten steel pool, the voices of people are boiling. In the fiery molten steel, there is actually a loading and unloading dock made of steel, and countless machine puppets are busy on the dock like diligent ants, salvaging and loading and unloading all kinds of machine puppets floating in the pool.

A robotic puppet snail like a small floating island is undoubtedly the most important thing in this loading and unloading work.

Dozens of steel cables were encircled around the back shell of the machine puppet snail, and hundreds of powerful bull-headed machine puppets pulled the steel ropes together. There is a smooth steel slope from the dock to the pool, and the robot puppet snail is pulling it ashore from the molten steel little by little. Not far behind the slope, in the center of the wharf, several huge high-hanging steel frames stand here, and huge iron grips hang down from the sky, waiting solemnly.

Catherine and the Ice Bear Abyss were surprised. Just now, when dozens of robot puppet monkeys jumped on the back of the snail to tie the steel cable, they all ignored the existence of the two of them. As early as when they saw the steel dock, the two began to discuss the various situations they might encounter in the future. Various options for negotiation, fighting, and escape have been discussed, including the worst-case scenario, a robot puppet on the dock that can communicate with reason, or the worst-case scenario, a group of robot puppets who don't know any pain and have to fight their way out.

But the two could never have imagined that they would be completely ignored. Catherine and the Ice Bear Abyss looked at each other, and finally chose to wait and see.

The robotic puppet snail is dragged up to the dock and all the way to the bottom of a giant high-hanging steel frame. Several huge iron grips fell from the sky and grabbed various parts of the snail's back shell. Catherine and the Ice Bear Abyss dodged left and right, giving way to those iron grabs.
