Roddy was stunned, feeling like a dream.

Back then, when she first saw Qin Di on Chihuo Island, when he was still a disciple of the Qi refining period, she didn't expect that in just five thousand years, he had already advanced to an earth immortal, and he had somehow become his own master, which was simply incredible.

However, this wonderful feeling was only for her personally, and it was not very strange if it was placed in the entire cultivation realm. There is a succession of hearing the Tao, and there is a specialization in the art industry, and Qin Di came to the top and became a master. What's more, she has already fallen once, and going out from the underworld is equivalent to starting a new life. In this difficult situation of incomplete soul, she can worship Qin Di as a teacher, which can be regarded as a creation.

After a long while, she came back to her senses, bowed down and said, "Thank you, Master, for teaching the Fa." ”

Qin Di smiled and said, "I came to the underworld this time to find the Three Treasures of the Netherworld, that is, ghost bones, dark stones, and hidden algae. Do you have any news about that?"

Luo Di glanced at him and replied cautiously: "Master, these three things are taboo in the underworld, and they are not allowed to be mined privately, let alone bought and sold. Once found out, it is a felony. So, if you ask openly, none of the shops will say yes. But privately, there are some reserves, but the amount is very small and the price is very expensive. Although I have worked here for more than a thousand years, and I am also a senior deacon of this store, I don't dare to give it to you secretly, and the pavilion master will pursue it. ”

Qin Di said: "Don't worry, I have a large number of spiritual materials in my hand, which can be exchanged for them." As he spoke, he threw out two cave worlds, which were all spirit immortal cave heavens carefully opened by the little peach tree, because the fairy spirit veins had not yet been extracted, so they did not collapse.

Luo Di took the goose egg-like cave sky, his divine sense swept in through the open portal, and said with a smile: "Master, you stay here for a while, I'll go and get the catalog of the secret storehouse, and then you think about what you want to change." With that, she went out and walked out.

After a while, she came in from outside, holding a jade slip in her hand.

"Master, look at it, it's all here. ”

Qin Di's divine sense swept over the jade slips, and it turned out that the local Heavenly Treasure Pavilion had a reserve of 100,000 Immortal Stones, three pieces of clothes made of high-grade Hidden Algae, and more than twenty ordinary Hidden Algae Clothes. In addition, there are six or seven Huangquan ghost bones.

"How much can I redeem for these things?"

Luo Di replied: "Master, my greatest authority can only sell you a high-grade cryptoalgae suit, five ordinary cryptoalgae clothes, the dark stone can provide you with one-third, and the Huangquan ghost bone can give you half, how about it?"

Qin Di nodded: "How many is how much, is there enough material in these two caves?"

"That's enough! As long as there is a cave sky, it is enough! After all, this is the Spirit Immortal Cave Heaven, not to mention those materials, just the fairy spirit vein, you can exchange a lot of things. The fairy vein is not expensive in the Spirit Mountain, but it is valuable in the underworld!"

"Okay, you can take both caves. Also, you can help me find a map of the underworld, and then find out where the Three Treasures of the Netherworld are found. ”

Luo Di wanted to speak and stopped, and finally looked at Qin Di and said, "Master, Tianbao Pavilion has indeed collected some information, and I can also give it to you." But where the Three Treasures of the Netherworld are produced, each one is very dangerous. Not only is there a complex array, but there are also strict guards, and almost every year, a group of people are captured and then executed by Ling Chi, it's really terrifying to think about!"

Qin Di smiled and said, "I just want to go over and have a look, but I may not really make a move." ”

Luo Di hesitated: "Then I'll bring you the information." ”

After a while, she took out a few pieces of jade slips and said, "Master, this is all basic information, and there is no detailed information. ”

Qin Di took the jade slip and said, "It's enough to have a map and basic information." Just know where it is. ”

His divine sense began to read the information in the jade slip, and then quickly learned that the places where the dark stones were produced were all in high places, either in the depths of the mountains or in the plateau mounds, and there were more than thirty places in total, all of which were divided by the three sects of immortals, demons and Buddhas. There is only one place of origin of Huangquan ghost bones and cryptoalgae, and that is "Huangquan Sea".

If you want to find Huangquanhai, you must first find the Lechuan River.

The Lethe River was full of blood, and all of that blood was gathered from under the graves, and it was filled with countless fragments of souls.

Descending along the Lechuan River, the terrain gets lower and lower, and finally a basin is formed. In the center of the basin is the Yellow Spring Sea. The Yellow Spring Sea is 3,000 miles in circumference, and there are nine springs at the bottom of the sea, which erupt from the ground until it is more than ten zhang high on the water surface. These nine springs are arranged in the shape of nine palaces, separated by thirty miles from each other.

There are cryptoalgae in the center of the Yellow Spring Sea for 500 miles, but only in the vicinity of the Nine Springs will there be high-grade cryptoalgae.

The bones fished out of the Huangquan Sea are all called Huangquan ghost bones, but only in the core position near Jiuquan, the Huangquan ghost bones fished out are of the highest level, and the best effect is to use it to cultivate the kung fu of the Yin Ghost Sect.

In addition, it is mentioned in these materials that in order to fish for cryptoalgae from the sea, it is necessary to have a special net. The general net melts when it comes into contact with blood and water, and it cannot be soaked in the Yellow Spring Sea, and only the silk spit out by a kind of yin silkworm produced in the underworld can scoop up the hidden algae.

So, Qin Di asked Luo Di to find this kind of net again.

Roddy went out to look for a long time, and only to get back two nets, one was only a few feet in size, and the other was slightly larger, but not more than two feet.

Qin Di instructed her to stay in the Heavenly Treasure Pavilion and wait, while he himself set out on his way.

The Lechuan River is a big river, and it is not known where it originated. But it is like the Tongtian River of the Origin World, which runs through almost all the big cities in the underworld. In other words, the main cities of the underworld are all on the banks of the Lethe River.

Qin Di easily found the Lechuan River on the edge of the Xudu City, and then flew downstream along the Lechuan River.

This river is very long, and with the strength of the seventh order of his Earth Immortals, he actually flew for three whole months before he saw that the ground in front of him had sunk significantly, and it was possible that it was almost to the Huangquan Sea.

Then, I saw that the ground was getting deeper and deeper, and the air around me was getting colder and colder, and there was a smell of blood in the air.

Further ahead, looking from a distance, he vaguely saw a formation membrane, which showed three colors, which seemed to be equivalent to a third-order immortal array.

Looking left and right, he also found that outside the array, there was a small palace every hundred miles, needless to say, the people who lived in the palace should be the guards guarding Huangquanhai.

Qin Di didn't dare to rush over suddenly, he stopped in the distance first and observed quietly.

After three days, he had a general understanding.

The skill of those guards is not too high, they are only equivalent to the late stage of Buxu, or the early stage of Merger. They come out every four hours to make rounds, and only three times a day. Normally, these people stay in the palace and don't know what they're doing.
