In the Lishan dungeon, Yuan Feng and others crossed the river composed of mercury and the surrounding retro buildings, and came to the imperial city of the ancient king.

If it is said that it is an imperial city, it is not exactly, because except for a walkable passageway. Except for some buildings in the imperial city, the ground is all mercury, which is the same as not asking for money.

"The ancient king is really wealthy, and he got so much mercury in that era, tsk."

Along the way, there was basically no moment when Yuan Feng couldn't see mercury in his sight, although he didn't know how big this underground imperial city was. Judging from the distance walked, half of the Pearl Academy already exists.

It is hard to imagine that a high school with an altitude of more than 1,000 meters has been hollowed out by the ancient king and created such an underground imperial city.

But the more this happened, the more curious Yuan Feng became.

The ancient king spent a lot of money to build the underground imperial city, why didn't he enter Lishan after his death. Where did he go?

"The largest building in front, according to the history of your Huaguo, should be the palace where the ancient king lived, right?" Looking at the front, which towering Jinluan hall, Asha Xinya looked at Yuan Feng on the side and asked for an answer.

Hearing the female fox's question, Yuan Feng raised his head and looked ahead, on a staircase composed of three white jade stones. There was a hall that looked dark overall, but it was majestic, and he already had a guess in his heart.

After having a guess, he put his guess and said to Asha Xinya and the others: "The dungeon we are in should be the epitome of Xianyang City two thousand years ago, so the palace in front of us should be Xianyang Palace." ”

"It stands to reason that there should be many palaces in the imperial city of your Huaguo Emperor, but now there is only one. Presumably, this Xianyang Palace should have some special significance for the ancient king, right? "Even if Asha Xinya doesn't know much about the history of China, she still knows some of the most basic things, so she put forward her own opinions.

"Xianyang Palace is a palace established by the ancient king in order to show his merits after unifying the six vassal states, what do you say is the meaning of this?" After explaining with a smile, he couldn't wait to step on the white jade staircase, wanting to see what was inside.

"I see, is this a palace that shows its strength and authority?"

After understanding, Asha Xinya was also interested in following up.

It's been a while since they've been in, and so far not a single undead has been seen, which convinced Asha Xinya that there was no trace of the undead here.

But if there is any trace of the undead, then who sent out the prestige of the monarch that those super-level mages suffered after entering Lishan, then it remains to be studied.

There were three white jade steps, each of which was very long, and Yuan Feng did not count them in detail. However, judging from the current situation, this white jade staircase should be five hundred meters, which is still very long.

However, after stepping on the white jade staircase, Yuan Feng felt something strange, especially his mind was particularly clear. The perception aspect seems to have been expanded, as if something has entered the mind and washed away the filth, which is very comfortable.

"How is it possible, since this ladder is cast by the Nian Stone!!"

On the quiet staircase, Hu Pa's shrill and incredulous voice suddenly sounded, making Yuan Feng withdraw from that refreshing state and cast his eyes on the other party.

"Steward Khoopa, what is a Nian Stone, isn't this some kind of magic treasure?" For the nian stone in Hu Pa's mouth, Yuan Feng was particularly interested.

Especially after stepping into the stairs, he couldn't forget the cool and comfortable feeling in his mind.

"Nian Shi? Probably not. ”

Nianshi, Asha Xinya has seen this thing, shouldn't it be all silver? The jade under your feet is obviously white, okay.

But even if there were doubts in her heart, Asha Xinya didn't say it. In fact, she had already discovered the improvement of her mental power.

I thought it was some special magic array, or magic props or something, but Hu Pa directly said that it was a reading stone, which really confused her.

With this thought, Asha Xinya squatted down and gently touched the white jade stairs under her feet with her hand, as if she was sensing something.

"Steward Hupa, what is the Nian Stone, isn't it a magic stone for cultivating spiritual power?"

Judging from the feelings just now, Yuan Feng found that his spiritual power had improved by a small step, although it was only a small step, but it was already a little terrifying for Yuan Feng.

You must know that your spiritual power is already at the peak of the third realm, and this small step out is the rhythm of breaking through the fourth realm!!

But such a cultivation treasure, Yuan Feng had never heard a single news, as if there was no Nian Stone in the world at all.

But now, from the disbelief on Asha Xinya's face. There is also the news that Hoopa has just revealed, which can completely prove that such a thing as a reading stone should exist.

Hearing Yuan Feng's voice, Hu Pa quickly restrained his expression, and thinking of the gaffe just now, he smiled apologetically: "I'm sorry Mr. Yuan Feng, it's my gaffe." ”

"It's okay, it's not in Hippo Butler, can you explain to me what a Nian Stone is?"

"Naturally." After Kupa nodded, he looked in the direction of Asha Xinya and dissuaded: "The Holy Maiden doesn't have to be groping, although this is a reading stone, it has not yet been refined, and it is normal that you don't know it." ”

"I see, I'll just say it."

The Nian Stone I have seen is a piece of silver and clear, and it is also dotted with many lines like a nebula circling, which is very easy to identify.

But the white jade corpse under his feet, not to mention any nebula patterns, even the color is different.

But now after Hupa's explanation, she realized that what she saw now was a refined chanting stone, no wonder she hadn't seen it.

"The Nian Stone is a special celestial stone that can greatly enhance the spiritual power of the magician, so that the spiritual system, the curse system, and the space system have been greatly improved."

When Hu Pa explained, Yuan Feng's eyes lit up directly, good guy. This thing is a good treasure that specializes in improving spiritual power, so there are three ladders here, isn't it?

"Don't think about Yuan Feng." Seeing the other party's thoughtful expression, Asha Xinya directly and unceremoniously interrupted his reverie, and explained: "In fact, every corner of this dungeon basically has the shadow of a magic enchantment.

The purpose is to ensure that the buildings here are not damaged, otherwise why would you think that after a thousand years, the things here are still intact? ”

"Uh... All right. Yuan Feng smiled wryly, but he still didn't give up and asked: "Then Steward Hupa, is there anything else on the market that sells this thing?" ”

It's decided, and when I go back, I'll find my grandfather and look for clues about the Nian Stone.

If you acquire such a treasure, your spiritual power will be improved again, and your strength will be raised to a higher level at that time.

It's a pity that Hupa shook his head and explained: "No, this kind of thing is priceless." ”

"Almost 100 years ago, someone discovered a vein of nemalite in Iceland, and at that time it was still a common rarity. In that era, super mages of the space system and even the mind department continued to emerge. ”

When talking about that time, Hupa's face revealed a hint of nostalgia, obviously missing the old days.

But it was only for a moment, and he quickly retracted his nostalgic expression and continued to explain: "It is the continuous emergence of mages from the space and mind systems that has caused the demand for the Nian Stone to be extremely high. One day, almost fifty years ago, the veins of Nianshi were mined out. ”

"That doesn't make sense, since there is a vein, then there should be a second one, isn't there anyone looking for it?"

"How could it be that no one was looking for it." Hearing Yuan Feng's question, Asha Xinya added on the side: "In fact, there were many old hunters who went into many places to search, but after all, they didn't find anything. ”

Hopa nodded his forehead, looked at his feet, and sighed, "Yes, but it is really an unpredictable thing to find the original mine of Nianshi here..."
