This is Feng Jiuxiao's treasure house, Fang Liuyun doesn't know who Feng Jiuxiao is, but Hong Yu understands.

How powerful the Xuanyuan Ancient Dynasty was back thenAccording to the description of the Qixi Sword Spirit to Hong Yu, the four major powers of Daxia, Dirong, Canglan, and Chuyue on the Qingyuan Continent are added up, and the comprehensive strength is far inferior to the Xuanyuan Ancient Dynasty.

Especially in that era, the level of research on forging, alchemy and other skills far exceeded that of now.

The many civilizations that have been destroyed have led to the severance of the inheritance, and the losses are too great.

And Feng Jiuxiao is one of the five masters in the history of the Xuanyuan Ancient Dynasty who can get the title of "Divine Creator" at the highest level. The fact that he chose this place to build a treasure house shows that the location itself is not simple.

When Hong Yu passed through the valley and saw the millions of red line swimming snakes, he felt that this place was not simple. After a brief look at it, the people of the Main God Domain thought that this was a very low-level ruin, but Hong Yu didn't think so.

With the help of the Qixi Sword Spirit, he found that the treasure house had been explored once in the distant past, so the truly powerful prohibition had long been broken, and it was difficult to find even traces, but this did not mean that it was really "traceless". Under careful observation, Hong Yu still found clues.

He led the way in front, and Fang Liuyun was even more surprised in the back, she had thought that Hong Yu was very mysterious before, but this close contact, she found that Young Master Yu was by no means as simple as it seemed on the surface.

The formation mantra that made her suddenly, and the illusion that appeared at any time that made people unaware of it, and the current ...... Hong Yu walked to the Zhongpiyang Stone Room, which was the real hub of the entire treasure house formation.

As soon as he raised his hand, a sharp blade appeared, waved it on the wall a few times, and a large piece of rock peeled off, fortunately, the passage outside was very long, and Hong Yu was very careful to catch these stones with martial energy, the sound was not loud, and it did not alarm the people outside.

"Guiding energy engraving line" Fang Liuyun saw that the hunting heart was happy, the detailed division of the formation engraving line, the concentrating engraving line, and the amplification engraving line have gradually been lost, and the current formation only has a single engraving line, and if you want to achieve a certain purpose, you can only rely on the formation structure. Let's say the concentrating formation structure. As a result, the efficiency is much lower.

And the ancient book of stone tablets that Hong Yu gave her was too profound, and there were no records of these "basic" things in it, so many parts of that ancient book of stone tablets were actually understood by Fang Liuyun, but there was no way to achieve it. Unexpectedly, in such an originally "low-level" ruins, the energy conduction line of the formation was accidentally discovered.

Fang Liuyun immediately excavated dozens of energy-guiding engraving lines and carefully put them away. At this time, even Fang Liuyun could see it: "No, even those few civilizations that have been lost, those who can use the energy guidance line in such a large area are also high-level large-scale formations, and it must be strange to place them in such a simple ruins."

Hong Yu nodded, and dug down along those energy guidance lines, and soon reached the ground, and some other unusual formation lines appeared

Fang Liuyun let out a low snort and pounced again: "Amplification engraved line"

This is the engraved line used to increase the power of the formation, and she still doesn't let go of any of them, and puts them all away.

continued to dig along those amplification lines, and gradually approached the dungeon that Wu Jiading had harvested. All the kicker lines converge on one point: under the dungeon.

Hong Yu dug up the underground palace, revealing a deep well that only allowed one person to go down

The nerves were cut directly from the rock, dark and bottomless, and there were a total of nine thick formation carvings on the wall of the well, extending from below, and combining with the previous amplification carving buttons.

Fang Liuyun was not calm again: "Gathering energy to carve the line"

Whether it is the previous conductive engraving line or the amplification engraving line, all the way to the current concentrating engraving line, all of them are flashing with bright silver light, which is a manifestation of the excessive energy accumulated in the formation engraving.

Hong Yu thought about it for a while and understood that this large-scale formation extracted some kind of energy from the ground to maintain the operation of the entire treasure house. Later, most of the prohibitions in the treasure house were destroyed, and there was no consumption, and the energy was deposited in the formation carving line.

Although Fang Liuyun was excited, he didn't dare to pounce on it like before, so he cut off the formation carving line. She looked at the dark well and was very jealous: "What is down there? Why does it make me feel palpitations?"

Hong Yu couldn't say clearly, although the Qixi Sword Spirit had experienced that era and knew the existence of Feng Jiuxiao's level, he didn't see Feng Jiuxiao arrange this treasure house with his own eyes.

A hint of cold feeling wafted up from the well, although there was no wind, but it made people shiver.

Hong Yu ran his martial arts and traveled all over his body before he felt more comfortable. He walked to the mouth of the well, and the cold feeling under the well hit again, more ferocious than before

In Hong Yu's acupoint, the novice Dharma slowly raised his head, opened his lips lightly, and the curling Buddha sound turned into a pale golden mist that warmed Hong Yu's whole body. The Buddha's light energy completely dispelled those coldnesses, and he was even forced to retreat into the deep well.

Fang Liuyun suddenly felt a burst of warmth, and the cold air was gone, she glanced at Hong Yu differently, and didn't ask much interestedly.

And in the deep well, when the Buddha's light energy in Hong Yu's body was spreading, there was a strange sound, getting deeper and deeper, as if something was about to be drilled out, but because the Buddha's light was shining, he immediately fled back.

Fang Liuyun was a girl after all, her face suddenly turned pale, and she grabbed Hong Yu's sleeve: "Otherwise, let's go back......"

Hong Yu glanced back at her and said with a smile: "That's a gathering engraving line, don't you want it?"

Fang Liuyun struggled, reluctant to glance at the formation carving, after all, the obsession with the formation overcame the fear: "If you dare to go down, I will go down too." ”

Hong Yu couldn't help laughing: "Coward, okay, follow me." ”

Just a sentence of the novice Dharma Xiang frightened the thing below, and the Dharma Venerable of the Great Day has not yet made a move, so what is Hong Yu afraid of

He went down the deep well. As soon as he was stunned, the strange sound just now appeared again, this time, it rushed down at a faster speed, and then the strange sound below was loud, and a sound of chirping came up, and it continued to strengthen through the narrow and deep well, and when it reached Fang Liuyun's ears, she was shocked with goosebumps all over her body, and her teeth chattered.

Hong Yu heard the secret laugh and didn't poke her.

"You start collecting those concentrating engraving lines, and I'll take care of the rest. ”

As soon as Hong Yu raised his hand, a little martial light fell, illuminating the entire deep well.

About dozens of zhang below, countless red-line swimming snakes crowded the entire deep well, and the snake's body rolled over, making people sick.

"Ah" Fang Liuyun screamed, but after those red-line swimming snakes discovered Hong Yu's martial energy, they screamed in surprise and hurriedly retreated.

However, the speed of the retreat of the red-line snake is not comparable to the speed of the falling of the martial energy, and the little bit of the martial energy light of the "Secret Study Sutra" fell into the group of snakes, and it was suddenly like a drop of water falling into the oil pot, and with a bang, all the red-line snakes were scurrying around, but the well was too narrow and there was no place to dodge. Those who couldn't dodge, once they were touched by the light of martial energy, the snake body was immediately melted away

Hong Yu's martial energy was shining brightly, and he maintained a speed that was neither fast nor slow. The red-line snakes chirped and retreated frantically. After a cup of tea, suddenly all the red line snakes were gone, Hong Yu went down to see, it turned out that there was a natural stone cave below.

The cave is only two people high, but the area is very large.

Hong Yu stood at the bottom of the well, and as soon as the light was released, the surrounding red-line snakes escaped in an instant

Hong Yu looked up, Fang Liuyun had already pulled out all the concentrating engraving lines and put them away, and then followed.

"It's so strange here. Fang Liuyun frowned and looked around.

Although she said it was strange, she couldn't tell what was strange. Hong Yu smiled slightly, and took back the martial aura light that shrouded his body. Once Fang Liuyun was exposed, a bone-chilling cold suddenly hit her, almost freezing her, and a warm feeling surrounded her again, and Hong Yu's martial aura light returned.

The coldness was much stronger than the feeling on it.

Hong Yu said: "Follow me." ”

The area of the crypt is vast, Hong Yu can roughly distinguish the direction, in front of them diagonally, it should be the valley that came in. He walked over and casually threw out a few clouds of martial light, and immediately he could see that there was a deep crack on the top of his head. Those red-line snakes must have climbed up from here.

And Hong Yu's heart moved, Lingjue found something, he swung the Qixi short sword, and the rocks around the crack were cut off one after another, revealing the formation carving line inside. Fang Liuyun exclaimed again: "Seal the engraved line"

There is a sealing formation here to limit the leakage of a large amount of cold qi.

She was about to rush over immediately, but when she reached the edge of Hong Yu's martial energy, she stopped and looked back at Hong Yu embarrassedly. Of course, Hong Yu will accompany her.

The higher Fang Liuyun's achievements, the happier Young Master Yu became. He is a young master, and his subordinates are getting more and more powerful, so he doesn't have to do it himself.

Fang Liuyun cut off the seal engraving, and Hong Yu took Fang Liuyun to another direction.

In the middle of this crypt, another naturally formed stalagmite.

Fang Liuyun said differently after seeing it: "Ice?"

The stalagmite is like an ice sculpture, and the cold is overwhelming. Standing here, even with Hong Yu's martial energy protection, he still felt very uncomfortable, and the deep chill pierced into the bones like an awl.

Hong Yu shook his head: "It's not ice, it's the cathode cold vein." ”

It's no wonder that in such a small place, there are millions of red line swimming snakes, no wonder Feng Jiuxiao would build his treasure house here. It turns out that there is a cathodic cold vein underground. Moreover, it is a cathode cold vein that has manifested its true form.
