In the blink of an eye, the dog king dug up the small slope and then dug out a hole.

The little green coccidia was not idle either. It squeaked beside the dog and kept urging it to dig hard. Guan Heng and everyone just watched. After a while, a deep hole appeared on the ground. Gradually, some of it was exposed.

What is in the middle of the soil layer appears.

Zhenwen looked at it carefully and immediately whispered: "It's that kind of metal ore, little green ball. You and Gouzi are so great, you found so many for us!"

"Woof woof, woof woof!" At this moment, the dog king raised his head and shouted, and the snake-headed corpse dogs around him who had been preparing for attack rushed to his side one by one and began to collect the fragments of metal ore in the soil.

Although they were much smaller than the entire ore, they could not hold up and the number continued to accumulate. Soon, there were several small mountains of metal ore fragments piled up around everyone.

"Not bad, not bad. I have gained a lot. More, more, more~~" Seeing more and more ores, Zhen Wen happily clapped her hands.

However, no matter how many metal ore fragments there are, there will be a time when they are all cleaned up. After more than ten breaths, the dogs finally could not find any fragments anymore.

"These are already quite a lot." Guan Heng used Jinxuan spiritual energy to squeeze the fragments into several square and rectangular blocks, and then said with a smile: "How about it, Zhenwen, is it enough?"

"Well, with these, plus what I found before, it's barely enough to replace the world-traveling flying boat and the tiger-headed flying boat with new shell armor." Zhenwen said happily: "Thank you, Brother Guan, oh, yes

Yes, and you."

While she was talking, she had already taken out a bunch of snacks, preserved fruits, dried meats, etc., and stuffed them into the dogs and the green coccidia. She smiled and said, "Have you worked hard? This is a reward for you all? Eat it, eat it."

"Zhizhi."

"Wow..."

The little green ball, the dog king, they were rewarded, it was so beautiful that they didn’t want it? They immediately screamed and ate it.

"This small slope area? It is very likely that the craftsmen who cast the stone house dumped the ore residue and scraps."

Guan Heng said casually: "In their eyes, these things may have no use anymore, so they would abandon them, but they didn't expect that thousands of years later, they would be recycled by us."

"Haha? That's it. Useless little things will be put to great use in the future, right? Brother Guan?" Hearing Zhenwen's words? Guan Heng nodded: "Yes, that's the truth."

At this moment, Qing Huang asked: "We have almost searched the stone house in the foundry. Should we leave now?"

"Wait a minute." At this moment, the crazy poisonous ant queen and the golden-haired wild monkey came running from not far away? They both said in unison: "Master Guan, there is a place I want you to take a look at."

"Oh?" Hearing this? Guan Heng asked casually: "Where?"

"Not far ahead, in the corner of another stone house."

While leading everyone forward, the golden-haired wild wolf said: "The queen ant and I inspected there just now and found a crack in the wall here? There seems to be other things stored inside? We think? This should be a 'mezzanine'.

"

"Mezzanine? This is quite strange. You have to go and see it." Guan Heng said.

…

After a few breaths, the wall in the corner of the stone house approached.

"Is this the crack in the wall?" Ruotao stepped forward, stretched out her hand and knocked on the edge of the crack, then nodded and said, "Yeah, the sound it makes is different from other places. There is indeed an interlayer."

"Sir, should we just pry open the cracks in the wall?"

"Okay, let's do it now." As he said that, Guan Heng winked at the mandrill and the old monkey. The two men immediately walked to the wall carrying ice-breakers and metal short sticks, and thrust the weapons into the gaps, just

After a few pulls, the area was expanded.

"Hey, is it a dark passage?"

"Well, this may be a section of the mountain that has been dug through, close to the stone house of the foundry. Let's go in and have a look."

As Guan Heng said this, he rushed to the front. No one could guarantee the absolute safety of the path ahead, so Guan Heng chose to walk at the front for safety.

"Huh -" After walking down about a dozen steps, a strange cold wind suddenly blew over. Guan Heng sneered slightly: "This way of saying hello is quite special. Now that you are here, don't leave!"

"Bah!" In the flash of lightning, Guan Heng suddenly grabbed the object flying in the wind. Qing Huang next to him immediately asked: "What is it?"

"It should be some kind of spirit body. Let's wait until we reach the ground below before checking." As he said that, Guan Heng kept walking and walked towards the stairs below. After walking dozens of steps, he came to the secret room underground.

Guan Heng waved his hand and said, "Make the area a little brighter."

"Hoo ho ho - chi chi chi chi -" upon hearing this, the evil goose mother immediately released seventeen or eight medium-sized fireballs, which immediately illuminated the surrounding area like daylight.

"The door to the secret room is here." Qinghuang and Qianxin saw this place, stepped forward and groped up and down with their hands, and then said in unison: "Why is it so tight that you can't find the door handle, not even the keyhole!"

"It is estimated that the builder did not want others to open the door, so he used cooled molten iron to seal the cracks in the door, so of course it is impossible to get in through ordinary methods."

With that said, Guan Heng had already stepped forward, and suddenly stretched out his hand to release the Jinxuan spiritual energy, "Swish, swish, swish!" In an instant, this breath wandered around, covering the entire metal door.

After a few breaths, he raised the corner of his mouth and smiled slightly: "Okay, find a small hole as big as a grain of rice, and just let my spiritual energy penetrate in..."

"Crack!"

"Clark!"

In just the blink of an eye, a harsh sound came from the gap at the edge of the metal door. Ruotao laughed in a low voice: "Is there hope?"

"Of course, the spiritual energy has penetrated into the depths of the gaps. I just need to slightly change their forms, that's it!"

"Crack!" It was too late to say, but soon, a gap opened by Xuan Lingqi suddenly appeared on the left side of the metal door from top to bottom. Guan Heng immediately pushed with his palm, "Crack!" The door was immediately closed inward.

The remaining foot width has been advanced.

"call--"

A turbid air that had been confined to the closed space for many years immediately flew out. Guan Heng waved his hand to disperse it. At the same time, the demon mandrill and the old monkey stepped forward together. They worked together and finally pushed the

The door was completely pushed open, and immediately after, Guan Heng and his companions filed in.

"Hey, there's also a foundry on the left?"

"The right side seems to be the storage warehouse."

"It's weird, why did the owner of this room set up his foundry in an underground no-man's land?" An Yan said with some confusion.

"Maybe this guy doesn't like to be seen when he's working, or maybe he has something special that he doesn't want to show to others." Guan Heng smiled and touched his chin, then said: "In short, let's search here now.
Chapter completed!
