Until the last moment when his eyes were closed, Xiao Yun still hadn't figured out the mystery in his heart.

One of the doubts, according to the records in the classics, this plant is extremely rare, although Xiao Yun does not want to admit it, but there is no doubt that it is indeed rare. No one knows where it grows, so no one can be sure where to see it. If it weren't for the fact that its function was not outstanding, Xiao Yun had no doubt that it would definitely be the object of competition among countless cultivators.

It's just that he doesn't know if his father's words are true, if there are really no more than ten places in the world where this kind of plant can grow, then where can the alchemists find such a spiritual material to refine psychedelic drugs?

The fact is also as he thought, throughout the ages, there have been alchemists who have found Bitengxiang, but there are only a handful. At present, it has been recorded and confirmed that there is only one person who has truly succeeded in refining the Biteng Phantom Incense, and this person is the "Medicine Emperor" five thousand years ago, Cassia Zi......

And even the place where the blue vine incense exists is more than the number of alchemists who have found it, so it can be seen what kind of plant it is.

It is such a plant, but Xiao Yun has seen it in different places twice.

In the past, Xiao Yun would definitely attribute it to his luck, but now it's different. He has grown up, especially in these few months in the Yanhua Empire, he has really grown, he has learned to think, and he is no longer what his father says like before.

Therefore, he was puzzled.

Countless people have never been able to see plants in their lives, and Xiao Yun, who is only sixteen, has seen them twice, this is not luck, it is a deliberate arrangement? Is it really his father's arrangement? The more I think about it, the more I feel that it is possible, after all, in the past three years, Xiao Yun has asked himself, and his father has the most mysteries.

The people closest to them, but the least familiar ones......

The second doubt is the man in black who has been in the shadows.

Ever since Xiao Yun left Yucheng, he had always felt that someone was secretly following him. At first, he only said that he was suspicious, but from the day he was thrown into the spirit circle by the mysterious man in black in the depths of the palace, he was sure that it was not that he was suspicious, but that it did exist.

Indeed, someone has been following him from Yucheng to the imperial capital Chang'an, and at this time he also came to this secret realm.

Xiao Yun concluded that the man in black who appeared several times before and after was related to his own father. But he didn't know who it was, what the man in black was going to do, and he didn't even know the relationship between the man in black and his father.

The more he felt that all of this was a game, and he was the one in the game.

Sadly, he didn't know what the bureau was trying to do.

Being in the game, the heart is already outside.

The third doubt is the strangeness of this secret realm.

By now, Xiao Yun's brain has been activated. Whether it was the various rumors in the Yanhua Empire, or the personal introductions of Han Shan and Luo Hu, Xiao Yun had no doubt that even the powerhouses of the Yuyuan Realm would face the danger of death and life when they arrived in this secret realm.

But they went too well.

As Han Shan and Luo Hu said before, it was too smooth, but it seemed a little weird.

It is true that when they came out of the underground palace, they did die nine times, and Xiao Yun died even once. But his "death" also gave him a blessing in disguise, and finally succeeded in escaping from the underground palace. Later, when he met the three beast kings, he thought that he would be in a catastrophe, but he accidentally found the entrance to the dragon purgatory.

Is this good luck? I'm afraid no one would think so.

Especially the old man surnamed Ye he had just met, the more Xiao Yun thought about it, the more he felt that his words were said on purpose. And if Xiao Yun expected it to be good, the old ghost Lin and the old man surnamed Ye must have known Huangfu Xue for a long time......

......

After thinking about it a lot, Xiao Yun's consciousness also began to be groggy, his eyes couldn't see clearly, his eyes were blurry, and there was a strange sound of rustling in his ears. His eyelids lost the strength to open, and finally, he fainted.

When he woke up again, he was the only one left by his side.

With a soft hum, Xiao Yun opened his eyes and slowly got up, he found that after he had just fallen from such a high cave wall, his body was not injured at all, not even scratches and bleeding.

This had to strike him as a little magical.

After examining his body several times, he found that there were indeed no other bruises, only injuries left after a few fights, and he looked up with confidence.

At a glance, he felt that this vertical hole was like a well that had been going through the years to the sky.

At this time, the entrance of the cave is like a soybean, and the light on the entrance of the cave comes and goes, probably at night. Looking at the size of the hole, Xiao Yun estimated that this vertical hole was at least a thousand zhang deep. And between the entrance of the cave and Xiao Yun, there were some dense black spots suspended, and Xiao Yun naturally knew that those black spots were the hanging human bodies he had seen before.

Now it seems that he did get to the bottom of this cave.

Retracting his gaze, Xiao Yun looked at the situation around him again.

Strange to say, at the bottom, there is plenty of light. He didn't have the patience to study the source of the light, because the first thing that caught his eye was a quaint stone table, and there were two stone benches next to the stone table, one on the left and one on the right, as if they were used for two people to drink.

When I got closer, there was a teapot on the stone table. There is a porcelain cup on the left and right, and if you look closely, there is still a little liquid left at the bottom of the cup in both teacups, which is caused by the reflux of liquid that should be attached to the wall of the cup.

The teacups were clean, and the stone tables and benches were free of dust, apparently cleaned.

Slowly sitting on a stone bench, Xiao Yun held the teacup in front of him, but the picture of the two drinking involuntarily appeared in front of him, you pour me a drink, so happy!

I didn't expect that under the hanging corpses of hundreds of people, at the bottom of the thousands of vertical holes, there are still people who can enjoy life so comfortably, it is really the size of the world, and there is no wonder.

"Huh?" Holding the teacup in his hand with his right hand, Xiao Yun suddenly exclaimed, he didn't expect that there was residual warmth on this teacup. It seems that the person who made the tea has not gone far yet, and there may be an urgent need to go out, Xiao Yun guessed.

Looking at it, the bottom of this cave can be said to be "the four walls of the house", except for the table in front of me, there is nothing else, and there is no stone door on the stone wall that can be opened.

Xiao Yun thought that there was no hiding place anyway, so it was better to sit here and wait for the return of his master. In Xiao Yun's heart, even the underground palace still has a dead master, and it is reasonable to say that there is an owner in this shaft.

Besides, looking at the teacup in front of him, this master should be much easier to deal with than the Seven Yamas of the Locked Corpse.

Thinking of this, he was reassured in his heart, although Han Shan and the others were separated from him like last time, at least he didn't have to worry about Murong Qingcheng's safety.

Boredom waiting, Xiao Yun rubbed the teacup in front of him with both hands, and suddenly brought the teacup to his nose, sniffed it gently, and a fragrance came to his nose. Suddenly refreshed, the dizziness brought by the blue vine fragrance disappeared most of the time.

"Good tea!" Xiao Yun praised, just smelling the rest of the smell could lift his spirits, and he couldn't help but grab another teacup on the other side, and also brought it to the tip of his nose. Only this time, it wasn't the fragrance of tea, Xiao Yun's eyebrows condensed slightly, "This smell ......"
