Removing the gravel at the door, Leo crouched down and picked up a fragment of the gate, the metal was engraved with juxtaposed lines, and people in this world would definitely think that it was some kind of spell totem.

Leo felt a burst of shock, this is definitely some kind of circuit, and this neat and regular beauty, the civilization that made this thing can at least do laser etching.

The traces of ancient civilization that he had been thinking about for a long time actually appeared on the mountain near his base camp in such a grand manner, coupled with the leakage tank that was suspected of causing the beast tide before, Leo vaguely began to feel that this place in the Northland might not be simple.

"Everyone's on alert! Class A is stationed on the periphery to ensure the way out, and Class B follows me in."

But be careful, if it is a soldier of this era, or a warlock, Leo has self-confidence in firearms to crush, but in the face of a prehistoric high civilization that does not know the roots, it is necessary to be vigilant.

There seems to be no end in sight to the long corridors, the rust on the neat metal plates on the walls tells the years, and the faint fluorescent light strips stretch all the way into the depths.

For the first time, Leo felt that he should find a way to recruit another Warlock, and in this case he could rely on the perception that some Warlocks possessed.

It's a pity that the cost of offering warlocks is very expensive, and aside from the rare wind magicians like Ral, who directly draw power from the atmosphere, most elemental warlocks use mediums when casting spells.

The strength of the elemental stone determines the strength of the spell cast, and even the fire crystal, which is not lacking in the land of iron, must be at least of the highest grade, the warlock.

- Burning money

The group went deeper, and the deeper they went, the more negligible the sunlight leaked into the passage, and the blue light emitted by the faint light strip was indescribably weird.

Although the soldiers were terrified, their legendary lord walked in front and had a little more confidence.

Leo didn't take the risk in vain to walk ahead, the dragon scales in his pocket have been trembling slightly since entering this building, as if he was alert to something, if there was any problem, he believed that he could be alert at the first time.

Since he brought out his own soldiers, he had to bring back a lot of them.

"It's all iron? I'm afraid it can be worth a lot of money, right? ”

"It's not promising!"

After a snap of his fingers on his face, Leo actually felt that there was some truth in his words, and these metal plates have not been corrupted for so many years, I am afraid that a lot of other substances have been added to them, maybe they can be studied.

Even if the content cannot be studied, at least something that is more than a thousand years old, even if it is an inexplicable fragment, there will be nobles willing to pay a lot of money to buy it.

After advancing almost two or three hundred meters or more, but still not seeing the end, Leo even suspected that the facility had hollowed out the entire interior of the mountain.

What kind of facilities are here, why was Bai brought here, the scales of the sound and the temperament similar to the sound on the white body all made him speculate one after another.

The dim light brightened slightly, and a metal partition door appeared in front of it, but the door seemed to have been damaged a long time ago, as if the surface coating had been destroyed, and it was more rotten than anything else.

When Leo finally managed to get through the damaged gap, he found that there was a dimly lit hall in front of him, and Bai Hao was sitting there dignified, dangling from something like a rotating chair, without the slightest appearance of being unfree.

"Ah, you're coming"

"What do you mean, you're here, I'm here to save you, okay?"

The familiar atmosphere that Leo had brewed to the present day collapsed with Shiro's playful greeting, and there was a frustration that he finally hit the bottom of the level, only to find that the reward chest was just a tabula rasa.

"Aren't you captured?"

"That's right, but ......"

Shiro looked at somewhere on the long table behind him, the black aura was enveloping, and there was no feeling of a living creature at all, so that Leo didn't even notice that there was another person here.

"Why don't you let this person talk about it? He seems to know you well? ”

"And me?"

Who can you get acquainted with? You have to know that you are a complete outsider, what does it have to do with the old antiques in this ruins?

"Long time no see..... Brother Leo"

The humanoid in the dark shadow spoke, and the voice was indeed vicissitudes, and listening to such an old man call himself brother really made Leo feel a little weird.

"Don't be surprised, maybe you don't know me now, but we used to have a good relationship"

Now, once, Leo, who had come over in the era of information explosion, instantly surged up countless speculations when he heard these two words, and he really had some kind of important plot?

"I didn't expect to see you again, after such a long time, even this research room is no longer what it was back then"

"But please believe that I will never betray you, whether it is the past or the present"

Leo was completely confused, just knowing that this person seemed to know him, or was it just a suspicion?

"He's not lying."

Shiro dangled his feet on the chair, making a tooth-sore sound, Leo nodded, there was actually some kind of speculation about Shiro's identity before, if that was the case, Shiro's words were still credible.

"I think you must have a lot of questions, but when you reach the top of the tree, there are all the answers."

"Those people woke me up and brought me the book"

"Them?"

Leo caught a word, but the old man obviously didn't want to explain it more, and just said it to himself.

"In exchange for hoping I caught her, but when I left here, I finally learned why you insisted on building the lab here in the first place."

"I've been secretly observing for a long time, but I haven't been in contact with you for a long time, maybe I don't have the courage, right? After all, you're still you, but I'm not who I used to be."

"They're all gone, and now it's just me, and even so, I'm satisfied to see you at the end..."

Leo understood the reason why the old man was talking to himself, and the old man's body had begun to dissipate, and particles kept flying from him.

I'm afraid that it can last until now is obsessed with it, what did I or myself do in a certain period of time that made this ancient man so concerned?

"It's not all gone..."

Bai turned his head and looked at the old man who was gradually dissipating, a sad emotion emanated, and he finally understood why the old man was able to steal her belongings, so it was.

"The five of us are still here..."

"So it was, it's like this"

The old man's eyes regained some brilliance, and he saw the shadow of the past from Bai in a trance, but he was relieved.

"Okay...... Okay..."

The old man completely dissipated, and the last trace of particles was dispersed in the air, and it became invisible, Leo didn't know why, and suddenly felt very sad, uncontrollable sadness.

Bai jumped out of his chair, walked to the place where the old man was sitting in front of him, picked up a book with a metallic sheen, and was speechless for a long time.

Looking at Leo, did he turn out to be the same person back then, maybe Yin didn't take risks for a group of stupid people for no reason, but instinctively noticed something, right? Walk up to Leo and hand him the book.

"If it were you, I think it would be usable, right?"
