After speaking, Hongrui shook his head, and then began to act, walked to the portrait of the ash dwarf, folded his hands, bowed seriously, and said silently: "May the ancestors bless." "It seems that the person on the portrait should be an ancestor of the Black Iron Clan, but I don't know who it is."

Immediately, Hongrui carefully took off the portrait and put it aside, as if he was looking for something in the original position of the portrait, and then, when he touched a certain brick, he was first stunned, then touched the brick twice, nodded, and pressed it hard.

There was a slight jolt on the ground, and a foot behind Hongrui opened between the grounds, revealing a staircase leading to the ground.

When the passage to the underground was completely opened, Hongrui walked down the stairs step by step, and Manager Hu on the side did not go down with this this time, but just stood in place and waited.

After a while, Hongrui came out of the underground passage, and after coming out, he pressed the brick that had opened the passage again, and the underground passage began to slowly close again.

After seeing the underground passage completely closed, Hongrui re-hung the portrait of the Black Iron Dwarf again. It can be seen that Hongrui attaches great importance to this underground passage.

After doing all this, Hongrui turned around and said lightly to Manager Hu: "Let's go." ”

Mr. Hu bowed down and nodded in response, "Yes." He pressed the mechanism to open the heavy metal door, and after Hongrui went out first, he followed.

Until the end, they didn't notice Nack's existence, and everything they did was seen by Nack.

Nack was alone in the secret room again, and Nack came out of the shadows and said regretfully, "It's a pity, it would have been nice if only Hongrui had come in just now." It was definitely a once-in-a-lifetime opportunity, but I didn't expect the manager Hu to follow. ”

Dealing with a high-level Dark Mage and a mid-level Dark Mage who was very close to the high level at the same time, Nack was not confident that he would be able to do it, so he had to go according to the plan.

It's just that Nack is very interested in what exactly is in the secret underground passage.

Nack took the portrait down with reference to Hongrui's previous actions, and since he still remembered the location that Hongrui had just knocked, the special brick was quickly found by Nack.

Nack followed Hongrui's example and pressed lightly on the brick, and the underground passage gradually opened and appeared in front of Nack's eyes.

To be honest, Nack was a little excited about me right now, and judging by the things on it, it was a lot of valuable stuff stored here. And in this room, there is a special secret room, and the things stored in it must be of much higher value, how can this not make Nack's heart move?

Nack walked down the stairs to the underground chamber, which was small, much smaller than the original, and contained only three simple things, all on a delicate and quaint table.

On the far left is the wooden box that Hongrui was holding when he came in, which Nack opened to see that there was a note and a beautiful bouquet of flowers with a light blue body, and a faint cold air was coming out.

"It seems that this is the frost nail flower that Hongrui just said. However, why did Hongrui say that with this frost armor flower, he could improve his chances of getting the Burning Flame of the Realm? With three fingers, Nack carefully pinched the frost nail flower, put it in front of his eyes and looked at it carefully for a while, and then muttered a little puzzled.

[Frost nail flower, living in a cold place, contains a huge frost and cold atmosphere, after eating, it will condense a layer of light frost on the body and meridians, like armor, so this flower is named.

And the reason why Hongrui would say that he could improve the chance of getting the Burning Flame of the Burning Realm should be because when obtaining the Burning Flame of the Burning Realm, the cold energy contained in the Frost Armor Flower could resist the heat emitted by a part of the Burning Flame of the Burning Realm. Yin explained aloud.

[So that's the case, so does this flower have any effect on me?] Nack then asked.

[The Burning Fire of the Calcining Realm is too domineering, even with the master's body, it is a very dangerous thing to forcibly absorb, the chance will not be very high, this frost armor flower is indeed helpful to the master. Yin replied.

After listening to Yin's analysis, Nack nodded, put the frost nail flower back into the wooden box, and opened the note that was placed with it.

The note listed how to make several pills and the materials needed, some of which were plants, some of which were parts of the monsters, and even the magic elements of these monsters. In addition, the note is very detailed, and the location where these materials may be found, how they were collected, and how they were preserved are all written on the side of these materials.

The name of the frost nail flower is also among them, and the name of the frost nail flower is circled, and there is a tick on the side, which should mean that it has been completed.

As for the production method, Nack didn't have time to study it now, so he just took a quick look and put the note back on, closed the wooden box, and put it away directly.

Placed in the middle of the table are two books, one of which is called "Eight Refinements of Hundred Fires", which is a fragment of a book that mainly tells about some forging techniques. In the other book below, it describes some of the experiences of the predecessors in learning "Hundred Fires and Eight Refinings". Nack unceremoniously put it away.

As for the one on the far right, there is a small silver metal beast, which is a two-headed body and has two small wings on its back. Maybe it's because of the needs of technology or some other aspects, some lines are relatively hard and mechanical, and you can tell at a glance that they are not living things.

Its head is not much smaller than its body, and it has two long tiger teeth, a bit like a saber-toothed tiger, and the two small wings on the shoulders, only a little bit, reach the waist when they are put away, and they are always a little wider than the head, which makes people wonder if the wings are decorative.

However, because of this, its appearance has become very cute, and it must be very lethal to girls, and girls who see it will definitely can't help but hug him.

But what's the use of such a thing? Is it just for selling cute? Since the Black Iron Clan will put this winged leopard here, it must not be just like this.

Nack picked up the leopard and looked at it carefully for a while, but he didn't see anything famous, and tried to put his magic into it. Sure enough, the little leopard reflected.

The leopard's body began to glow, and then these lights slowly condensed into a unique line throughout its body, these lines were like a river, and the leopard's body was constantly flowing, and their destination was a pair of eyes of the leopard.
