In the underground fantasy world, it took more than ten months, and with the help of the Panshan Dragon, the immortal yuan stone vein was finally mined!

Now, a pan-mountain dragon can't find a few immortal yuan stones after tossing underground for two or three days, so Du Long ended the mining of the underground immortal yuan stone veins under the advice of Jieling Ling'er!

Yi Tianxuan and Lu Hong'er knew a few months ago that Du Long had actually discovered an underground Immortal Yuan Stone vein, and they also asked the Piercing Mountain Dragon to help mine the Immortal Yuan Stone on a whim, and the couple then figured out why he had so many Immortal Yuan Stones to buy his own Ethereal Grass.

Fortunately, most of the Xianyuan stones mined in the last few months are middle-grade and lower-grade Xianyuan stones, if the two of them know that there are even a lot of top-grade Xianyuan stones at the beginning, I don't know if they will be shocked to drop their jaws?!

After staying in the underground fantasy world for nearly a year, in addition to the Immortal Yuan Stone vein, their group was still wandering around, collecting a large number of high-grade immortal medicinal materials, and during this time, they were lucky enough to get a Seven Star Ethereal Spirit Grass!

Due to various reasons, the feeling of getting the Seven-Star Ethereal Spirit Grass is actually even more exciting than getting some eight-star and nine-star immortal medicinal materials, after all, this thing is too rare, and the medicinal effect is so magical!

In addition to a large number of immortal medicinal materials, their group also collected a lot of Chalk Star Stones in the underground world, which is also one of the mission items of this Dire Star Trip, an ore that the Adventure Alliance has explicitly ordered to collect!

Chalk Star Stone is also one of the important ores needed for some kind of refining, along with black tungsten steel, it is one of the ores that has a special effect on soul power, and it is an important raw material necessary for the foundation stones of some psychedelic arrays!

In addition to the Chalk Star Stone, Du Long and the others were also lucky enough to obtain several other ores that were extremely useful in refining weapons, in short, the underground fantasy world was like a treasure land that had not been set foot on by outsiders, and it was really rewarding to stray!

On this day, Du Long finally decided to leave this rich treasure land, the one-year mission period is about to expire, I don't know how much trouble I will encounter on the way back, and it is reasonable to return to Sifang Valley a month or two in advance!

Secretly collected all the dinosaur monsters who were willing to go with him into the Qinglang Cave, Du Long took Xia Qinglian, Fu Zhu and Yi Lu and his wife to embark on the return journey, as for Qin Huofeng, the daughters were not members of the mission team this time, so it was better to stay in the cave for the time being!

It can be seen from the smiles on their faces that this trip to the chalk star can be described as a full return, and they are naturally full of joy and joy!

Du Long originally wanted to return to the surface along the same way he entered, but that road was far away, after all, the entire underground world was thousands of miles long, and they finally decided to go out along the hole where the Yi Lu couple entered!

Sure enough, after only flying a hundred miles, they found the entrance to the cave where Yi Lu and his wife had entered, and the group of five people happened to be the appearance of an adventurous five-person team, presumably it would not arouse the suspicion of outsiders when they arrived in the outside world!

Walking up along the entrance of the cave, the five people soon came to the crack of the cave where Yi Lu and his wife had sneaked in, and when Yi Tianxuan was about to lead everyone up along the gap, he was suddenly stopped by Du Long: "Stop!

By his sudden voice, everyone stopped in amazement, looked at him curiously, but no one spoke, all stared at Du Long curiously, waiting for his further explanation!

It's a pity that Du Long didn't open his mouth to continue to say anything, but frowned and showed a look of listening to something on his face, and stood there fixedly!

In Du Long's mind, a picture appeared at this moment, it was the interior of a cave, Lin Fengyun was sitting next to a desk with a gloomy face and drinking alcohol, and a cold old man in black was standing quietly behind him.

"Du Long! Lin Fengyun and this old man are in the cave hundreds of meters away above your head, that old man is the initial strength of the Great Luo True Immortal, that is, the strength of the Seven Stars Perfection! Although his immortal consciousness is affected by the cave, it can also cover a radius of hundreds of meters, as long as you go up a few dozen meters, you will enter the coverage of his immortal sense!"

It was precisely because of the faint warning voice of the ring spirit Ling'er, coupled with the sudden flash of the picture, that Du Long would hold Yi Tianxuan and send a warning to everyone.

Under normal circumstances, he knew that in order to train himself, Ring Spirit Ling'er would not tell himself about some crises in advance, but since he had warned in advance, it meant that there should be other greater dangers lurking in the shadows!

As if he knew what Du Long was thinking, Ring Spirit Ling'er didn't sell it, and continued to explain: "Outside this cave, there are hundreds of five- to six-star level adventurers scattered in all directions, and it seems that they are all following the command of these two people!

Since this Lin Fengyun's identity is relatively sensitive, if you want to collide with him head-on, or even want to kill him, it is best to think of a perfect strategy, otherwise, once the Lin family makes an all-out move, I am afraid that even the leader of the Danqi Second Alliance will not be able to protect you!"

Nodding secretly, Du Long finally understood why Ring Ling Ling'er didn't take this opportunity to train herself this time, she was probably worried that when she collided with Lin Fengyun head-on, she would kill him by mistake, it was easy to kill, but it was difficult to face the anger of the Lin clan!

'Hmph!' Du Long snorted angrily: "This surnamed Lin has sent people to assassinate me one after another, could it be that just because he is the son of the Lin family, he can kill whoever he wants, and others can't fight back?!"

'It's not impossible to do it if you want to, but I hope you can think about it calmly, once the news of your killing of the Lin family is leaked out, I'm afraid that the entire Purple Moon Immortal Bay Star Domain will no longer have a place for you!' Ring Spirit Ling'er reminded in a deep voice.

'Ling'er!' After a little hesitation, Du Long still opened his mouth and asked, "Is the Lin clan very powerful?!, could it be that I now have the best Immortal Yuan Stone, and I already have the basic combat power of the Nine Stars Consummation, plus the artistic conception of the Xuanyang Nine Stacked Waves, and the Red Flame Slashing Superb Immortal Soldiers, can I still not fight them?!"

'I'll tell you the truth!' Ring Ling Ling'er couldn't help but remind, "According to my recent scanning and exploration of the Lin Clan's mansion in Bibo City, this family is indeed worthy of being one of the five major families of Bibo Star and even the entire Purple Moon Immortal Bay, and there are dozens of Great Luo True Immortal level existences inside the Lin Clan's Mansion in Bibo City alone, and there are seven people who have reached the Great Luo True Immortal Perfection level!"

Du Long was obviously stunned, and said in disbelief: "Isn't it?!In just one Lin family mansion, there are so many Da Luo True Immortals?!...... That's incredible, isn't it?!'

'What's so strange about this?!' Ring Spirit Ling'er sighed lightly: "Many clans in the Immortal Realm have existed for hundreds of millions of years, and in such a long period of time, it is not difficult to grow up to such a Great Luo True Immortal-level existence!

Du Long obviously understood the meaning of the Ring Spirit Ling'er, in the immortal world, the existence of the Da Luo True Immortal level was like a carp crossing the river, but there were not many truly top-level existences!

However, even if it was just an ordinary Daluo True Immortal Perfection level existence, to Du Long, it was still like a mountain in front of him, after all, he still only relied on the combination of the best Immortal Yuan Stone and the Xuanwu Dragon Armor to have extraordinary combat power!

Standing there steadily, Du Long's face was uncertain, and he was assassinated by the Lin clan again and again, and this time Lin Fengyun was even more blocked in the cave where the exit was located, which made him very unwilling in his heart!

Could it be that he is going to retreat silently like this, leaving the underground world through another farther exit?!

'Du Long, what the hell is going on?!' Yi Tianxuan finally couldn't help but ask, the immortal senses of several of them could only detect less than a hundred meters away in this cave at most, so they didn't know the situation in the cave above.

While everyone was anxiously waiting, Du Long was about to open his mouth to explain, but when he saw that Lin Fengyun actually spoke in the picture in his mind, Du Long hurriedly stretched out his hand to Yi Tianxuan and the others, and made a silent action, which turned his attention to what Lin Fengyun was saying.

In the picture, Lin Fengyun finally put down his wine glass, and said with some impatience: "It's been a few months, why is there still no news of that Yi Tianxuan and Lu Hong'er?!, those two dog men and women should not be killed by the dinosaur monster group together with the Minhang team?!"

"......" The corners of Zhong Yan's mouth, who was standing respectfully behind him, twitched, but he didn't know how to answer the question, and finally could only remain silent.

"Uncle Zhong!" Lin Fengyun spoke again: "This time, Young Master Ben must get his hands on that ethereal grass, so no matter what, he must find that Yi Tianxuan and Lu Hong'er, he must see people alive and corpses when he dies!"

"Young Master, just relax, let's relax!, not only have we laid a net in the dense forest where they disappeared, but we have also laid an eyeliner in the teleportation array of the Sifang Valley and the headquarters of the Blue Wave Star Adventure Alliance, unless they really die in the Chalk Star, they will definitely not be able to escape our tracking!" Zhong Qian could only comfort in the end.

Nodding, Lin Fengyun stopped talking nonsense, picked up the wine glass again and began to drink the stuffy wine, his face looked extremely ugly, Zhong Xuan on the side groaned slightly, and still spoke again to comfort: "Young Master, as far as the old slave knows, the mission deadline for Yi Tianxuan and Lu Hong'er is in these two months, presumably even if they hide in some corner, they should be ready to come out and return to Bibo Star, right?!"

As long as he comes forward, we will definitely be able to take it down as soon as possible, and this time, for the sake of convenience, the old slave will also replace the internal guards of the Adventure Alliance guarding the teleportation array in the Sifang Valley with our Lin clan's people!

Lin Fengyun nodded with satisfaction and said, "What Uncle Zhong said is very true! It is estimated that success or failure will be determined here, unless that pair of dog men and women really die, they will definitely show their heads!"

In the cave hundreds of meters below the cracks in the ground, Du Long frowned and listened to the conversation between the two above, and finally figured out that this Lin Fengyun didn't want to trouble himself this time, it turned out that he was still here for the ethereal grass!
