However, the place selected by Huang Fei was about two or three meters away from the position that Murong Xianglong had just measured.

"What are you looking for there, not there, I measured it. Murong Xianglong saw Huang Fei running to a place so far away from him to grope, and hurriedly reminded him that he had found the wrong place.

Huang Fei ignored him, his hands and ten fingers kept beating on the grass as if he was playing a piano, taking the place where he was squatting as the center of the circle, exploring around.

"No need to touch it, it can't be there. Murong Xianglong was still standing there and talking.

Suddenly, Huang Fei's hands stopped moving, and his feet slowly moved two steps forward, but his hands kept pressing there without moving.

"What's the matter, what did you find?" Murong Xianglong also discovered Huang Fei's abnormality, and hurriedly walked over and stood in front of Huang Fei and asked.

"This is it. Huang Fei said with some joy, he turned over the grass covering the back of his hand, and an iron handle the thickness of a water pipe was exposed.

"How could it be? How did you come here? Did you change places again? I can't be mistaken. Murong Xianglong looked at his feet, and then looked at the place he had just measured, this gap is too big, if it is a few centimeters wrong, it can be said, but this is a few meters away.

"The place hasn't changed, and you're not mistaken, but there's a bit of a misunderstanding here. Huang Fei let go of his hand and stood up, moved his body and said.

"What misunderstanding?" Murong Xianglong didn't understand what else could be misunderstood here.

"How old are you?" Huang Fei asked as he looked at Murong Xianglong.

"Thirteen or fourteen. Murong Xianglong thought for a moment and replied.

"Yes, when you were thirteen or fourteen years old, how old are you now?" Huang Fei reminded Murong Xianglong.

"Oh, look at me, patronizing the matter of gold coins, ignoring all this. Murong Xianglong patted his head and finally figured it out.

How long can his legs be when he is thirteen or fourteen years old? It must be incomparable with now, he only remembers how many steps he should take, but forgets that his legs have also grown over the years, and now two steps are on top of the previous three steps, if it is not over, there will be no ghosts?

"How should this be opened?" Huang Fei pointed to the handle on the ground and asked, now that the door has been found, the next thing to do is to find a way to get in.

"This... Murong Xianglong scratched his scalp again, he had never opened this door by himself, but he had seen others open it, but it was only four or five strong men who could open it together, and he came in a hurry today, and he didn't care about this matter, besides, at this time, where can I find someone?

"What's the matter, Brother Long?" Seeing Murong look embarrassed at Long, Huang Fei guessed that there must be some problem in front of him.

"I haven't opened this door, I used to see that they were opened by several people together, just the two of us, I'm afraid I won't be able to open it. Murong Xianglong said with some worry.

"Then what should I do?" Huang Fei was a little anxious, this is all here, if he can't open the door again, won't it be another trip for nothing?

"Let's get out, try it first, and if it really doesn't work, think of another way. Murong Xianglong rolled up his sleeves, bent over, grabbed the thick handle of the water pipe with both hands, and began to pull it up.

The green tendons on Murong Xianglong's forehead burst out, but the door on the ground was still unmoving, and there was not even a sound of opening the door.

"Could this door be locked?" Huang Fei stretched out his hand to remove the grass near the doorknob, but he didn't see any keyholes, so there should be no locks.

"Hmmm... Murong Xianglong's throat made such a sound, which showed that he had used all the strength of his body, but this iron gate seemed to grow on the ground, and it didn't move at all.

As soon as Murong Xianglong let go, he sat on the ground with his buttocks, panting heavily, the sweat on his forehead began to flow down, he was exhausted.

"Why don't you help out. After gasping for breath a few times, Murong Xianglong asked Huang Fei breathlessly why he didn't help.

"I'll try it, you sit down first. Huang Fei made a few lower-waist movements, then moved his body again, spat at his palm, rubbed it, and then bent over, stepped on the ground with both feet, held the handle tightly with both hands, took a deep breath, and gritted his teeth.

Just like Murong Xianglong, Huang Fei's throat also let out a low roar, and both of his arms began to tremble.

"Squeak", there was a sudden slight noise in the silent garden.

Murong Xianglong's eyes widened suddenly, he heard it right, this sound came from under Huang Fei's feet.

Then something even more surprising happened, the grass on the ground began to tremble, and it became more and more violent, and cracks appeared around the two-meter-square piece of land in front of him, and slowly tilted.

"Wow, Hercules. Murong Xianglong couldn't help but sigh.

Seeing the dark hole in front of him, and seeing the green tendons exposed all over Huang Fei's body, Murong Xianglong couldn't believe his eyes, this is too good.

"Ahh Huang Fei let out a low roar, lifted the iron plate in his hand, and slowly put it on the ground.

"Whew. Huang Fei sat on the ground all of a sudden, I don't know when, the clothes on his body were already soaked with sweat, and the sweat on his head was dripping down like rain.

"This thing is too heavy. Huang Fei gasped for breath and didn't forget to sigh.

Murong Xianglong squatted next to the iron gate that had been leveled, shining a flashlight in his hand, and his mouth made exclamations from time to time.

He hadn't paid attention to it before, but today he paid special attention to it and found that the thickness of this iron door was more than forty centimeters, where is this still a door, it is simply a piece of iron lumps, no wonder when he was young, he saw that they had to be several strong men together to open the door, and it was for a long time because of this reason.

"Huang Fei, are you really a mortal? Why do I think you just want to be like four immortals, you can pull up such a heavy thing, admire, I really admire it. Murong Xianglong gave Huang Fei a thumbs up, with a look of admiration, and he almost knelt down and kowtowed twice.

"I'm tired too. Huang Fei said weakly, he used all the strength of his body today, and he almost collapsed, thinking that he would have to cover this door when he came out in a while, he had a headache.

Why did this Murong Zejian make such a thick iron door? I'm afraid that it can't even explode through a bomb, right?

"How are you feeling, can you still walk?" Murong Xianglong also saw that Huang Fei was tired, and asked with concern.

"It's okay, let's go down quickly, or it will be dawn in a while. Huang Fei struggled to get up from the ground, and now he felt that both of his legs were going limp.

"Good. Murong nodded to Long in agreement, but still stretched out his hands to support Huang Fei.

Going down from the cave is the staircase, Huang Fei and Murong Xianglong flashed their flashlights and walked down the stairs, this staircase is still a spiral staircase, turning down in a circle, going deeper and deeper the further down.

Huang Fei felt that his head was about to turn dizzy, he estimated that he was at least ten meters underground now, he really couldn't figure it out, what was the purpose of building an underground secret room so deep?

After a few more turns, Huang Fei and Murong Xianglong suddenly stopped, Huang Fei had a crying and laughing expression on his face, while Murong Xianglong only had an expression of wanting to cry.

In front of the two of them was another large iron door, and there was a large lock hanging on it.

"Brother Long, have you really been here?" Huang Fei turned his head to look at Murong Xianglong, wanting to ask him what was going on, why did he suddenly have an extra door here?

"I didn't have it before, I never remember that there was such a door here, it must have been installed later. Murong hurriedly explained to Long to prove his innocence.

"Okay, it doesn't matter anymore, the question is, what should we do next?" Huang Fei pointed to the lock hanging on the door, looked at Murong Xianglong and asked.

"This... Murong Xianglong grabbed his hair, then lowered his head and looked around.

"What are you looking for?" asked Huang Fei.

"Find a rock and smash the lock open. Murong said without raising his head to the dragon.

"I didn't see a stone along the way, so where can I find it? Huang Fei didn't believe that Murong Xianglong could find the stone.

Sure enough, Murong turned around the dragon several times, not to mention a stone, and he didn't even see a grain of sand.

"What can I do about this?" Murong Xianglong suddenly deflated, and sat on the steps, holding his head in his hands, not knowing what to do.

"Do you have any steel wires or anything like that?" Huang Fei asked suddenly.

"Huh?" Murong raised his head to the dragon, not understanding what Huang Fei was saying.

"Steel wire, iron wire can be, harder, thinner. Huang Fei stretched out his hand and gestured.

Murong Xianglong reached out and rummaged through his pocket, but found nothing.

"Nope. Murong Xianglong shook his head at Huang Fei, who would have that thing on his body if he was fine.

"What can I do about this?" Huang Fei also sat down.

"Why don't you go back and look for it now?" Murong Xianglong stood up suddenly, he felt that it should be too late to go back and find a hammer or something.

"When. As Murong Xianglong stood up, a sound of metal hitting the ground came from under his feet, and the two of them took a flashlight, and a bunch of keys were lying at Murong Xianglong's feet.

"No, this thing will do. Huang Fei happily picked up the key, looked at it in his hand, and then returned all the keys on it and gave it back to Murong Xianglong, leaving only the key ring.

"What do you want this thing for?" Murong Xianglong asked with a puzzled expression as he stared at the keyring in Huang Fei's hand.

"Unlock. Huang Fei said as he reached out and broke the keyring, slowly straightened it up, and bent a small hook at the very front.

"Unlocking,, are you making movies or have you watched too many movies?" Murong Xianglong looked at Huang Fei in surprise, watching him take the key ring in his hand and walk towards the lock on the iron door.

"Come and help me take care of it. Huang Fei waved at Murong and the dragon, and then lifted the lock hanging on the door with his left hand.
