In the blink of an eye, the Dog King dug the small soil slope and then dig out the hole.

The little green cocciferus was not idle either. He squeaked beside the dog, constantly urging it to dig hard. Guan Heng and everyone watched it. In a short while, a deep hole appeared on the ground, and gradually, something exposed in the middle of the soil layer appeared.

Zhenwen looked carefully and immediately shouted: "It's that kind of metal ore, a small green ball, you and the dog are so great, and you have found so many for us!"

"Woom, woo!" At this moment, the dog king raised his head and called out. The snake-headed corpse dogs around him who had been ready to go rushed to it one by one and began to collect the pieces of metal ore in the soil.

Although they are much smaller than the entire ore, they cannot hold back the number of them. Soon, a few hills of metal ore fragments piled up around everyone.

"It's not bad, I've gained a lot, I'll have more, I'll have more~~" Seeing more ores, Zhenwen happily clapped her face.

However, no matter how many metal ore fragments are cleaned up, they finally couldn't find any fragments after more than ten breaths.

"There are already quite a lot of these." Guan Heng used the Jinxuan spiritual energy to squeeze the fragments into several squares, rectangular blocks, and then smiled and said, "How is it, Zhenwen, is it enough?"

"Well, with these, and what I found before, it is barely enough to replace the Tigerhead Flying Boat and the Tigerhead Flying Boat with new shell armor." Zhenwen said happily: "Thank you Brother Guan, oh, by the way, you guys."

While she was talking, she had already taken out a bunch of snacks, dried fruits, jerky meat, etc., and stuffed them to the dogs and the little green cocciferus, and smiled and said, "Thank you for your hard work? Is this a reward for you? Eat it."

"Squeak."

"Wangwu..."

The little green ball, the dog king, were rewarded, so beautiful? I immediately shouted and started eating.

"This small earth slope area? It is very likely that the craftsmen who cast this stone house dumped ore residues."

Guan Heng said casually: "In their eyes, these things may be useless? They will be abandoned. But they didn't expect that thousands of years later, they will be recycled and utilized by us."

"Haha? That's it. Useless little things will be used for a large amount after accumulating a lot, right? Brother Guan?" Hearing Zhenwen's words, Guan Heng nodded: "That's right, that's the reason."

At this moment, Qing Huang asked, "We have searched for this casting stone house, so should we leave now?"

"Wait." At this moment, the Crazy Poison Ant Queen, the Golden Retriever, came from not far away? They both said in unison: "Master Guan, there is a place I want to ask you all to take a look."

"Oh?" Hearing this, Guan Heng asked casually: "Where is it?"

"Just not far ahead, the corner of another stone house."

While leading everyone forward? The Golden Retriever said, "Just now, Queen Ant and I patrolled there and found a crack on the wall here? There seems to be other things in it? We think? This should be a 'mezzanine'."

"Sandwich? This is very strange, so you have to go and have a look." Guan Heng said.

...

After a few breaths, the walls in the corner of the stone house were approaching.

"Is this the crack in that wall?" Ruotao walked forward, reached out and tapped the edge of the gap, and nodded, "Yeah, the sounds made are different from other locations, and there is indeed a mezzanine."

"Young Master, should we just pry the crack in the wall?"

"Okay, let's do it right now." As he said that, Guan Heng winked at the demon horn. The two of them immediately walked to the wall with their icebreakers and short metal sticks, poked the weapon into the gap. They just pulled it a few times and expanded the place.

"Hey, is it a dark passage?"

"Well, this may be a piece of dug through the mountain belly, close to the stone house in the casting room. Let's go in and take a look."

Guan Heng said while walking ahead, no one could guarantee the absolute safety of the path ahead, so Guan Heng chose to be at the forefront to make it safe.

"Hu——" After walking down about a dozen steps, a strange cold wind suddenly blew over. Guan Heng sneered slightly: "This way of greeting is quite special. Since you are here, don't leave!"

"Bang!" In the flash of lightning, Guan Heng suddenly took action and grabbed the object flying with the wind. Qing Huang next to him immediately asked, "What is it?"

"It should be some kind of spirit. Let's wait until the level below to check." As he said that, Guan Heng kept walking and heading towards the stairs below. After walking dozens of steps, he came to the secret room underground. Guan Heng waved his hand and said, "Lighten the nearby ones a little."

"Huhuhuhuhu-hehehu-hehehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-hehe-he-he-he-he-he-he-he

"The door of the secret room is here." Qing Huang and Yan Xin saw this place, walked up and groped up and down with her hands, and then said in unison: "How can you fit the thread tightly? You can't find the door handle, and you don't even have a keyhole!"

"It is probably because the builder doesn't want others to open this door, so he uses cooled molten iron to seal the cracks, so of course the general method cannot be entered."

As he said that, Guan Heng had already stepped forward and suddenly reached out to release the Jinxuan spiritual energy. "Swoosh!" In an instant, this breath wandered around and covered the entire metal door.

After counting breaths, he smiled slightly with his mouth: "Okay, find a small hole the size of a rice grain, just let my spiritual energy penetrate..."

"Crack!"

"Clala!"

In just a 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 gap. I just need to change their shape slightly, that's it!"

"Crack!" It was said at a time, and soon, a gap opened by Xuan Lingqi appeared on the left side of the metal door from top to bottom. Guan Heng immediately pushed out his palm, "Gee!" The door was immediately pushed into the inside for more than a foot wide.

"call--"

A stream of turbid air that had been specially used in the enclosed space for many years immediately flew out, and Guan Heng waved his hand to disperse it. At the same time, the magic lord and the old monkey walked forward together. They tried hard together and finally pushed the door open completely. Then, Guan Heng and his companions entered one after another.

"Hey, there is also a casting room on the left?"

“It seems to be a storage on the right.”

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