The loosening of the seal of the cave immediately attracted everyone's attention, and they couldn't help but feel a burst of joy that it was finally time to come. After a while, the clouds and mist on the seal slowly dispersed, and the ice and snow melted under the scorching sun, and a huge gap appeared.

After that, all the Adepts in the presence rushed into the cavern, as if they were afraid that others would grab the treasure first. However, there was more or less gang cooperation between them, and there were very few lone wanderers, because they did not dare to fall behind, but slowed down the speed, Feng Jiu and Yun Jiu Ge took the lead, first entered the cave in pairs, and it didn't take long to find a silver light curtain in front of them and break in.

Through the silver curtain of light, Feng Jiu found himself in a completely new world. He breathed a rich and fresh aura all of a sudden, and couldn't help but feel relaxed and happy, and at a glance he saw the vast deep mountains and ancient forests, among which there were many powerful demon beasts lurking.

"This is really an independent space opened up by the ancient immortal cultivators, I didn't expect to meet it in the era of the supernatural with thin aura, it seems that my path to cultivating immortals is promising, only by controlling here, my cultivation can be multiplied day by day!" Feng Jiu's heart was full of anticipation, he and Yun Jiu Ge did not stay in place, they were like fish in water here as immortal cultivators.

After the two disappeared, a large group of other supernatural beings finally entered the place, including people from the five major royal families. Yu Wenba and Hua Lingfeng were angry for a while, they didn't expect the two of them to run so fast, so they couldn't catch up, and they originally wanted to follow.

"Brother Hua, don't worry about Yun Jiuge and that little beast, anyway, we are not their opponents head-on, the top priority is to rush to the Ancient Underground Palace and find the old lady of the Hua family, so that we can be more sure to deal with them!" Yuwen Ba felt Hua Lingfeng's hesitation, groaned for a while, and persuaded him.

"What Brother Yuwen said is extremely true, but now I finally understand why we can't feel the abnormal fluctuations on that little beast's body, it turns out that he is an immortal cultivator, I suspect that he has a shocking secret hidden in him, maybe it is more valuable than the immortal cultivation inheritance here!" Hua Lingfeng shared his thoughts and thoughts, causing Yuwen Ba to be shocked for a while.

"Brother Hua, is this true? If that's the case, we can't miss this little brute! No wonder you want us to follow them, it turned out that they wanted to find an opportunity to attack, but they were obviously wary and didn't want people to follow, plus we are not Yun Jiuge's opponents, so it's better to follow the original plan!"

Although Yu Wenba had some doubts, he understood that Hua Lingfeng would not be untargeted, thinking of all kinds of abnormalities and unimaginable strength on Feng Jiu's body, it was estimated that this matter was true nine times out of ten, and he couldn't help but show greed. But he understands the weight of the two of them, and therefore needs a bigger backer to carry it out.

"I understand, so finding my father is the last word, Yun Jiu Ge and the little beast will return to the Ancient Dungeon sooner or later, and we can just wait for the rabbit there!" Hua Lingfeng smiled gloomily, and the two of them took the two teams and couldn't wait to rush to the location of the Ancient Dungeon.

Ximen Ling and his son Ximen Yu obviously had similar plans, waiting for the old lady who found their family in the Ancient Underground Palace to make a move on Feng Jiu again, but they didn't guess the identity of Feng Jiu's immortal cultivator and the shocking secret he possessed.

Although Yun Mu also wanted to find the old lady of the Yun family as a backer, his purpose was completely different, he was to force Yun Jiu Ge back to the family, so that there would be two people with abilities above the SS level in the family, and it would be no problem to become the first royal family in Yundu.

As for the Situ family, they were a little at a loss, Sikong Lingmo had obviously learned the news that his old lady's whereabouts were unknown, and he didn't know if he would appear after the discovery of the ancient underground palace this time? If they hadn't appeared, it would be difficult for their Sikong family to compete with other royal families, and even break away from the royal family's name after this time.

"Dad, can we find grandpa this time?" asked Sikong Lian'er worriedly.

Sikong Lingmo sighed lightly and said comfortingly: "Lian'er, I believe that your grandfather Jiren has his own natural appearance, and he will definitely appear in the Ancient Underground Palace this time." Even if it doesn't appear, we have reached a cooperative relationship with Yun Jiu Ge and Feng Jiu to ensure that our family will not fall behind in this treasure battle in the Ancient Dungeon!"

"Daddy, can you tell me how grandpa disappeared without a trace?" Sikong Lian'er asked suspiciously, and asked without giving up.

"Dad doesn't know, but according to the news from the Ximen family, I heard that your grandfather and the old lady of the Ximen family encountered an extremely powerful demon beast together, and they were chased and killed before they dispersed, so your grandfather's whereabouts are unknown!" Sikong Lingmo said truthfully.

"Dad, do you really believe the words of the Ximen family? Maybe it's because of the old lady and grandfather of the Ximen family—" Sikong Lian'er questioned for a while, and before she could finish speaking, she was interrupted by Sikong Lingmo.

"Okay, Lian'er, our Sikong family has been friends with the Ximen family for so long, I don't believe that their family would do such a bad thing. The relationship between the two of us has finally been repaired, don't make any trouble!" Sikong Lingmo said solemnly.

Sikong Lian'er could only reluctantly agree, after all, she had no evidence, but since she saw Ximen Yu's true face, she felt a burst of rejection towards this so-called brother, otherwise she would not have gone on a hunger strike for more than half a month to express resistance.

At this time, Feng Jiu and Yun Jiu Ge had already distanced themselves from the others, she was obviously quite familiar with this place, and with a beautiful woman like her by his side, he was still relatively relieved.

"Jiu Ge, where do you think the location of the Ancient Underground Palace will be?" Feng Jiu asked curiously.

"In the past, when I was in the secret realm of Yundu, almost all the surrounding areas were explored, but the central location was extremely risky and could not be easily approached, and I thought the ancient underground palace should be there. Feng Jiu, as long as we keep heading north, we can reach the Ancient Underground Palace, and then we can join the Sikong family!"

"I see, as long as I know the general route, I feel much more relieved. Jiu Ge, there are a lot of elixirs that can be picked along the way, and there is just one plant fifty meters northwest of us, it shouldn't matter if it is offset a little, right?" Feng Jiu smiled indifferently.

"How do you know there's an elixir there?" Yun Jiu Ge asked in surprise.

"Jiu Ge, don't forget, I am an alchemy master, and I am born with a very strong sense of elixir, where the aura is stronger, I can sense it at once, but it is limited to a radius of 100 miles. As long as we can collect more elixirs in the Yundu Secret Realm and refine them into elixirs through me, it will only be of great benefit to us!" Feng Jiu explained methodically.

"I understand, that Feng Jiu, let's go immediately!" Yun Jiu Ge couldn't wait.

"Jiu Ge, don't be too happy too early, generally the elixir will be guarded by demon beasts, and it will inevitably be a fight! But with our strength, as long as we don't encounter the demon beasts of the Yuan Infant Stage, we should be able to deal with it!" Feng Jiu said with a solemn face.

"Feng Jiu, what you said is extremely true, no wonder when I stumbled upon some medicinal materials before, there would be demon beasts coming out. Then since your sense of the elixir is so spiritual, can you see what kind of strength the demon beast guarding this elixir will be?" At this time, the two of them had already seen the figure of the elixir, and it was a red twilight grass, emitting a bewitching red light.

"This red twilight grass has at least two grades or more, and the demon beast that guards it will only be the strength of the foundation, Jiu Ge, you don't have to make a move, I can easily solve it!" Feng Jiu smiled slightly, and immediately separated a shadow as a way to obstruct his eyes, and grabbed the red twilight grass.

A small red yin fire snake hiding in the grass immediately pounced and spat out a mouthful of blazing yin fire attack, only to extinguish the shadow, only to find out that he had been fooled.

And the Red Yin Fire Snake was too late to react, and Feng Jiu's black shadow swept past its side at once, slashing it out of nowhere, breaking it into two pieces and dying, and it was he who used Hidden Shadow Absolute and Shadow Kill one after another.

So Feng Jiu successfully pocketed the red twilight grass, and also included the corpse of the Red Yin Fire Snake, the corpse of the demon beast is still more useful to him, which not only has a demon pill that can be refined, but also can be collected as a material for spiritual weapons.

Seeing this, Yun Jiu Ge chuckled, and then asked, "That Feng Jiu, if you encounter a demon beast above the Jindan stage, can you handle it alone?"

Feng Jiu Zhengse said: "The Jindan period is to survive the catastrophe, and there is a world of difference from the foundation building period, if I am an ordinary immortal cultivator in the foundation building period, I really can't fight against the demon beasts of the Jindan period." But you also know that I am extraordinary, if it is a demon beast in the middle stage of Jindan, I should be able to compete for one or two!"

"Well, Feng Jiu, you are indeed extraordinary, you are simply a little demon, since you became an immortal cultivator, I have only felt your unimaginable strength. Then if you encounter a mid-stage Jindan demon beast, I won't make a move, just give you a test of the water!" Yun Jiu Ge pursed his lips, obviously wanting to stay outside and watch the show.

"Okay, I won't let you down!" Feng Jiu naturally understood Yun Jiuge's thoughts, and responded confidently.

After that, the two of them had a smooth journey, and they didn't delay much time because of killing demon beasts and picking elixirs, and those demon beasts in the foundation building period were not the enemies of Feng Jiu at all, and they could easily take it down by using the Hidden Shadow Absolute combined with the Shadow Kill. Therefore, he picked a lot of second-grade elixirs, and the two of them had unknowingly arrived at the interior of the secret realm of Yundu.

Although the demon beasts here are not as numerous as those on the periphery, most of them are above the Jindan stage, which is obviously not easy to deal with. After some rushing, Feng Jiu noticed that there was an elixir of more than three grades sixty meters to the northeast, and his face finally became solemn.

Yun Jiuge noticed that Feng Jiu's face was different, as if he had time to ask, "Feng Jiu, what's the matter? Now you are going to start facing the Jindan Stage Demon Beasts, are you sure? I am really not sure, I can reluctantly make a move!"

"How can you not be sure?Jiu Ge, you just watch me return triumphantly!" Feng Jiu smiled slightly, since he said such a big thing, he was naturally sure, but it would take some time.

So Feng Jiu did not hesitate to go to the location of the three-grade elixir, and startled the snake as before......
