In the face of everything in front of him, Liu Hengfeng was a little inexplicable, in his opinion, the biggest possibility was that this was completely a trap to hunt and kill himself, but now, around the empty bamboo, Liu Hengfeng used his powerful divine sense to find no one's existence, and Liu Hengfeng began to doubt his original guess. Now everything is not important, the important thing is that he has to save the empty bamboo from here, and in the case of no one to see it, he is confident that he has such strength.

Using the way of time and space, Liu Hengfeng quietly sneaked into the place where Kongzhu was imprisoned, and what caught Liu Hengfeng's eyes was a cage full of streamers, and Liu Hengfeng knew that this was the legendary prison cage.

Streams of mystical energy came out of it, and after careful inspection, Liu Hengfeng found that those streamers were the tracks left by ancient words when they were moving. The entire prison cage is like the earth, composed of different longitudes and latitudes, and these words that seem to be like streamers are indistinguishable, interdependent and mutually restrictive, forming a very mysterious prohibition, this is Liu Hengfeng's view of the prison cage, of course, Liu Hengfeng knows that the prison cage has some other functions that he does not know, and the predecessors who created the prison cage cannot just want the prison cage to trap the enemy, but his existence is too long, so that no one knows its true purpose.

Liu Hengfeng knew that in order to rescue the empty bamboo of the prison god cage, he must first break the mysterious and ancient prohibition of this prison god cage, but now Liu Hengfeng has no understanding of this prison god cage, and he has no way to break the ban at all, unless he knows the way to open the prison god cage.

"No wonder there is no one to guard it! I believe that except for a few people who know how to open the prison cage, others have nothing to do with him!" Regarding the original opinion, Liu Hengfeng denied it, after all, there are not many people in this world who can break the ban of the prison god cage, either they know the prohibition very well and study it deeply, or they are strong enough to break the law with their strength, obviously, Liu Hengfeng has no way to do these two possibilities at present. "Is there really no way?"

Liu Hengfeng began to ponder, and suddenly, Jian Zun's words made his eyes suddenly light up, which was what Jian Zun told him when he was practicing swords. "There will be flaws in any trick, but the more clever the sword move, the smaller the flaws, and it is not easy to be discovered!" Thinking of this, Liu Hengfeng was excited.

"That's right, anything in the world will have weaknesses as long as he exists, if I can find the weakness of this prison cage, I believe I still have a way to rescue the demon monk!" Thinking of this, Liu Hengfeng's gaze no longer wandered, but became extremely firm, as the so-called nothing difficult in the world, only afraid of people with hearts.

Liu Hengfeng restrained his breath, after all, this is in other people's territory, if it is discovered, Liu Hengfeng knows that he has the ability to escape, but that will not only cause trouble, but also bring certain difficulties to future rescue, so Liu Hengfeng is extremely cautious. He studied the way the cage worked, the energy supply, and everything else, and he wanted to find out its weaknesses.

For three days, Liu Hengfeng did not sleep, he was studying this prison cage, the more he studied, the more Liu Hengfeng was surprised, the prison god cage is not an ordinary skilled craftsman can complete, his precision is beyond words. "Ingenious workmanship, real ingenious workmanship! It really deserves to be an artifact that has existed since ancient times!" This is Liu Hengfeng's heartfelt sigh, besides, he can't find a more accurate word to describe everything he sees, but now he must destroy this ingenious artifact, otherwise the empty bamboo will be trapped in it forever.

"Master, is there a way for you to break through this prison cage? Or do you know its weakness?" Ten days passed, but Liu Hengfeng still didn't make any progress, and he began to ask Jian Zun for help as a last resort.

"This thing is older than I am, and I haven't studied it, so I really can't help you this time!"

Jian Zun's words directly threw Liu Hengfeng from the clouds into the abyss, originally Liu Hengfeng was full of confidence, he knew that with Jian Zun's vision, he would definitely be able to find the weakness of the prison cage, although he was just a sword that had existed for endless years. I didn't expect that even Jianzun couldn't do it.

"Boy, being a teacher is not omnipotent, sometimes you have to test yourself, if you break this prison cage, you kid is enough to shake and shake the entire Three Realms! After all, in addition to mastering the method of opening it, no one has yet done it directly!"

"Master, I want to break it, but also make it not lose its value, and now the difficulty is here!"

"Stinky boy, remember, you can't have both fish and bear's paws, you think about it now, do you want to save people, or do you want to get this prison cage? If you want to save people, don't think about anything else, if you want to get the prison cage, don't care about the people inside, find a way to open the prison cage, but the people inside may not be able to wait until you find the way, after all, in this prison cage, isolated from the aura of heaven and earth, it is difficult to stay in it for too long without an immortal body!"

Jian Zun's was like a slap in the face, which made Liu Hengfeng feel ashamed, he didn't understand the truth that fish and bear paws could not have both, but he didn't expect the power of the prison cage, and he made such a low-level mistake.

"Master, I know it's wrong, I'll find a way to break through this prison cage!"

"You kid has always been affectionate, this is also the main reason why I fancy you, yes, you didn't disappoint me!Boy, come on, I believe you can do it, after all, your kid is my disciple of Jianzun!" Jianzun's words made Liu Hengfeng speechless again, if he did it, it would be the credit of Jianzun?!

"I finally know what it means to be brazen!" this is what the Sky Sword said to Liu Hengfeng.

Three months have passed, Liu Hengfeng doesn't know what the situation of the empty bamboo is inside, and he still can't find out the weakness of the prison cage in three months. Liu Hengfeng is not in a hurry, after all, this is the existence of endless years, it is not easy to find out its weakness, he can clearly sense that the empty bamboo is still alive, because the aura that the jade slip he left for the empty bamboo is still there, they have already set a simple prohibition when exchanging the jade slip, if the other party dies, the jade slip will also be broken and pass the news to the other party.

"Wait, when Kongzhu came to the Ruins Land to look for me, why didn't he find me through the breath of Jade Jian? instead, he inquired around the Ruins Land and left?" This question startled Liu Hengfeng, what does this mean Liu Hengfeng is very clear, at least it means that Kongzhu doesn't want to find him, "He must want to protect me!" Liu Hengfeng came to such a conclusion, so he stopped thinking about this matter and devoted himself to studying the prohibition of the prison god cage. He believes that as long as the kung fu is deep, the iron pestle can also be sharpened into a needle.

For half a year, Liu Hengfeng still hasn't found out the flaws in the prison cage, but compared to before, he is more confident than at a loss, and now if he is given enough time and materials, he can also imitate a prison cage, in other words, he knows everything about the prison cage. However, he could sense that the aura of the empty bamboo had become weaker and weaker in the past half a year, and if he didn't hurry up, maybe the empty bamboo would die in the prison cage.

Despite this, Liu Hengfeng still has no way to break the prison cage, after all, it is not an easy task to find the weakness of the prison god cage, even Jian Zun can't see the flaws, Liu Hengfeng may take a longer time to find.
