Several box-shaped carts drove by, and Catherine saw one with indigenous creatures sitting on it, and another with planks that she had seen on the ground before.

The indigenous chiefs also found Catherine's size problem. He stood next to a box-shaped car and thought for a moment, then cried out loudly. The passing box-shaped carts suddenly stopped, and the indigenous creatures pulling the carts listened to his command and gathered the box-shaped carts together. The box-shaped cars are connected from head to tail, and ten cars are picked up in one go. The planks that were originally transported were also collected and laid on box carts.

When it was finished, a flatbed truck appeared in front of me. Catherine and the Ice Bear Abyss could barely sit on it.

The indigenous leader sat at the front of the flatbed and shouted at the native creatures to pull up the flatbed and make its way to the depths of the cave.

Catherine and the Ice Bear Abyss, although they can enjoy the "ride service", are still vigilant. Along the road, indigenous creatures continue to join the ranks of pulling carts or carts, and flatbed carts are moving faster and faster, whizzing past long metal poles.

Catherine was frightened by this alarming speed. That's when she realized that the aboriginal creatures pulling the carts were nowhere to be found. The wheels of the flatbed truck and the long metal rod flickered incessantly, as if the alchemical patterns of the two interacted to stimulate some kind of energy, propelling the flatbed at high speed. The indigenous creatures that originally pulled the cart only provided a start-up momentum.

After driving for dozens of minutes, the flatbed truck suddenly opened up and entered a large underground space. There are countless indigenous creatures busy here.

Some of them are gathered on the left, and "ding-ding-ding" is mining. They built scaffolding against the mine wall, which was tens of meters high. The ore is chiseled directly from the top wall and transported to a box cart under the scaffolding. The box-shaped cart is transported along the long metal pole laid on the ground to the smelting equipment on the right side of the space. There were huge furnaces into which truckloads of ore were poured into which molten iron was burned. The molten iron is transported forward following a special pipe, which is run parallel to the flatbed truck that Catherine sits on.

Soon, Catherine saw the casting mold filled with molten iron. These molds come in a variety of shapes, large or small. The larger one was bigger than Catherine's, and the smaller one was the size of the palm of your hand. The shape of the mold looks like different machine parts, and it is not known what it will be when assembled.

After the molds are filled with molten iron, indigenous creatures load them onto special flatbed trucks. This flatbed is very similar to the flatbed truck that Catherine and the others are riding. The flatbed truck drove deeper with the casting mold.

Catherine was interested in seeing where the molds would go, but the flatbed truck she was on was rerouted and drove out of the large underground space and on.

The rest of the journey became monotonous, with no other indigenous creatures or box carts along the way. The long metal poles laid on the ground emit a faint silver glow, zigzag and zigzag into the depths of the earth.

Catherine could clearly feel that they were moving very slowly and gradually underground. I don't know how long I drove like this, and I don't know how deep it went underground, but the flatbed truck suddenly stopped.

The indigenous leader jumped out of the car and beckoned the two to follow him on. There was a black rumbling in front of it, and it looked like there was no way out at all. The tentacles of the indigenous leader shone brightly, and there was a face on the ground. The facial features are clear, but the eyes are closed.

The native leader stepped forward, stomped the face, and kicked it hard. His face hurt and he opened his eyes suddenly. Two rays of light shine through the eyes, projecting onto the wall. There was also a face on the wall, which opened its eyes to the light. Another ray of light shone out, pointing to the next face.

Then one face after another lit up, leading into the distance, showing the way.

This road is a tunnel, not high and a little narrow, but fortunately, you can barely walk into the ice bear abyss. The temperature in the tunnel was very low, and it didn't go far before Catherine let out a white breath from her mouth. I didn't feel cold in the ice and snow outside, but it's very cold here.

Faces are the best signposts. After walking with his face for a long time, the temperature in the tunnel became lower and lower. Catherine wondered where she would end up.

The native leader was already shivering with cold, and the tentacles on his head were half-drooping. He struggled to walk, and every step he took felt like he had exhausted all his strength.

The indigenous leader fell to the ground, his whole body covered with hoarfrost, and he froze.

Catherine hesitated, crouched down and knocked on the native leader, hard as a stone.

"I'll take him. Ice Bear Abyss said.

Although there is no indigenous leader to lead the way, you will not get lost by looking at those faces.

As you go deeper into the tunnel, the faces on the tunnel walls become more and more numerous and brighter. The cold wind blew in front of them, and even Catherine and the Ice Bear Abyss felt unusually cold.

But the two persevered.

After more than an hour of trekking, we finally reached the end of the tunnel despite the bitter cold. There was a huge human face there. The walls around it were crowded with small faces, and the eyes of each small face looked into the eyes of the big face, so the eyes on the huge human face were very bright. Its mouth was wide open, and ice and snow were blowing out of it. That's probably why the whole tunnel is so cold.

Catherine tightened her thickened robes and looked into the mouth of the huge face, a shower of snow scraping against her face. She touched her face with her hand, squinting to see that there was a ramp inside, and she didn't know where it led.

The mage looked back at the old barbarian and smiled, "It seems a little narrow to you. ”

"You want to go down?" the Ice Bear Abyss squeezed over and glanced over.

"It's all here, do you want to go back the way you came?" said Catherine, patting the huge human face.

"Yes. The Ice Bear Abyss reached out and lifted the native leader towards the ramp, "Then let him explore the path first." ”

The Ice Bear Abyss let go of his hand. The native leader, frozen to stone, slid down the ramp, and disappeared for a moment.

The two of them leaned together and listened quietly with their big mouths. Unfortunately, after waiting for ten minutes, I didn't hear anything but the wind.

"I'll go down. Catherine said as she pulled the soul chain from her chest.

She handed one end of the soul chain to the Ice Bear Abyss. "Just in case, pull me up when you hear me shouting. Catherine burrowed into the mouth of the giant human face.

"Are you sure you want to be able to go down alone?" the Ice Bear Abyss felt that something was wrong.

"Sure. As soon as Catherine's hand was released, the man began to slide down, "Remember to pull me up when I shouted." ”

Catherine slid down the ramp, soul chains pulling out of her chest. Catherine hadn't tried how long the soul chains could stretch.

She slid down for five, ten, fifteen minutes......

She felt a little weak, and she noticed that her hands were shaking, and she wondered if it was because it was too cold.
