It was not the first time that Sun Zichao had heard this sentence, and seeing that Han Du didn't say anything, he naturally didn't ask any more.

Han Du began to walk around the giant's dungeon with Sun Zichao, who were dwarfs compared to the buildings built by the giants.

In the silence, the sound of their footsteps echoed, giving people a sense of unease.

"Brother Han, the atmosphere is so quiet, I'm a little scared." Sun Zichao unconsciously approached Han Du's side.

Han Du touched his gun with his own gun and said, "Hold your gun tight, what is there to be afraid of." ”

Sun Zichao was still a little uneasy, and his eyes swept around.

"Brother Han, listen, there seems to be a faint voice coming."

Han Du was a little distracted by him, and looked around, but didn't hear any sound.

"Shut up and don't mess with yourself."

After Han Du finished speaking, he stopped in front of a ten-meter-tall building, this building was very strange, the top was wavy, the windows were leaf-shaped, and the gate was a regular triangle.

Han Du stepped forward and touched the surface of the building with his hand, it was very hard, a bit like cement, but it was obviously not, because it was very silky to the touch.

Han Du was still guessing why the building was so well preserved, which might be related to the materials of the building, and of course, it could also be related to the fact that the underground city had been sealed underground.

He then tried to push the door open, and the triangular door opened to both sides, revealing many large, regularly shaped craters.

Han Du and Sun Zichao walked in, and they suddenly felt like they had entered a palace, because it was too vast inside.

Han Du approached one of the large pits and saw a thick layer of ash inside, which should have been once made by giants who had made fires and forged something.

Han Du continued to look at the second big pit, which was also covered with a thick layer of ashes.

Sun Zichao went to see other big pits for Han Du, and the same was true.

"Brother Han, there's nothing to see here, didn't the giant play barbecue here back then." Sun Tzu is super whimsical.

Han Du didn't speak, and chose to jump down decisively.

When his foot stepped on it, it sank slightly, and then he felt something it.

Han Du didn't dare to grope directly with his hands, and used the barrel of the gun to fiddle with the ashes, and soon pulled out a small pit, revealing a blood-red stone inside.

The shape of the stone is irregular, like ore mined in the mountains.

He picked it up and looked at it carefully, the color on it was not dyed, it should be naturally this color.

Han Du continued to fiddle with the ashes with the barrel of his gun, and found that there were many such blood-red stones inside, as many as a dozen of them.

Han Du handed the stone in his hand to Sun Zichao on the edge of the big pit, and then turned over and got up.

When he came up, he pulled out a blood-red crystal stone the size of a goose egg, the color of which was exactly the same color as the stone.

"Brother Han, where did the stone in your hand come from?" Sun Zichao asked when he saw this.

Han Du: "The leopard came back from nowhere." ”

Now Han Du's interest in the blood-red crystal stone in his hand has increased greatly, and it is obvious that it is made from the blood-red ore in the big pit.

Unable to think of what this crystal stone could do at the moment, Han Du put it back in his pocket, left the house with Sun Zichao, and continued to check in the other rooms.

Sun Zichao was reluctant to hold the stone in his hand, thinking that it was a treasure, so he carefully stuffed it into his trouser pocket and propped up the trouser pocket.

They went to the second room next to it, and when they opened the triangular door, they saw that it was laid out in the same way as the first room, with many large pits and a thick layer of ash underneath. He jumped down and tossed away the ashes, and there were still a dozen pieces of blood-red ore underneath.

They left the room and went to the next room to check, and found that it was all the same.

In this way, Han Du and the others confirmed that this dungeon was actually a place where blood-red ore was smelted.

It's just completely unclear what these giants are doing smelting ore for, and where these ores come from.

Han Du was a little frustrated, he had been tossing for so long and had found nothing.

"Brother Han, don't be discouraged, we still have one last room that we haven't checked." Sun Zichao actually came to comfort Han Du.

Han Du: "Where?" ”

Sun Zichao pointed to the cliff where they came down, where there was actually a ten-meter-tall house, but after they came down, they walked forward and ignored the house.

Now Han Du was also going to go back, so he walked back, and also planned to take a look at the house by the way.

The two of them walked up to the house and found that it looked similar in appearance to the other houses, but the door of this house was locked.

The giant's locks looked a little strange, with a semicircular shape and had been preserved until now, but they could not be opened without a key.

Han Du's method was very simple, he used a gun to shoot, he himself picked up the machine gun, clicked and shot at the door lock, and in less than a minute, the door lock was broken.

Then, they pushed open the tattered door and entered it together.

They were shocked by the layout of the house, and at first glance they thought it was a modern factory, because there was a lot of machinery and equipment in it.

"Damn, these giants can't be aliens, why do they still have factories?" Sun Zichao was surprised.

Han Du was also surprised, and walked up to these mechanical equipment made of unknown materials, and found that it seemed to be a whole production line, and at the equipment in front of him, there was an entrance where something was placed.

He suddenly had a bold idea, asking Sun Zichao to take out his piece of blood-red ore dug out of the fire pit and put it into this entrance to see the reaction.

Sun Zichao did so and stuffed the stone through the entrance, only to hear a ding-dong sound, and the stone was silent for a while after entering.

Han Du and Sun Zichao thought that throwing the stone into it would not work, but suddenly, a button at the entrance of the throwing lit up.

Han Du looked at this change and understood that the ore burned in those big pits was actually the fuel for this production line.

Sun Zichao was more bold and asked Han Du: "Brother Han, why don't I press this button down and see what happens later?" ”

Han Du was also very curious about these mechanical equipment, and nodded in agreement.

So, Sun Zichao's hand gently pressed the light-emitting button, and the entire production line began to make a rumbling mechanical sound, and at this time, the blood-red ore thrown into it could be heard being squeezed, and it was easily squeezed and broken.

Han Du looked inside along the entrance and found that the ore had been squeezed into blood-red powder.

After that, something happened that Han Du and Sun Zichao regretted very much, the blood-red powder was transported out, and it was transported into a large silver box at the end of the production line, and I don't know if it was made of metal, and then the big silver box was opened, and it was actually cold inside.

It seemed to be a freezer, and when the cold air dissipated, Han Du saw that there were frozen creatures lying on the partition inside, like several babies with gloomy faces.

There were three of the babies, all of them sprinkled with the blood-red powder, and their eyes opened suddenly.

There was no cuteness in the pupils of the baby's eyes, which were full of moisture, because they were covered with scarlet.
