The three of them quickly searched three more factories, but found nothing. Only the last factory was left. Yu Fei looked up at the factory in front of him, which looked quite eerie and strange under the moonlight, and unconsciously Clenching the Dragon Soul Sword in his hand, he took a deep breath and said solemnly: "The entrance to the underground palace must be in the last factory building. It must be full of dangers. Everyone, please be prepared," he said At this point, his brows suddenly relaxed again, he turned to Kun Yuanzi and smiled slightly, and said: "Taoist Master, let me let you, the mentor of the Ghost Dao, see what it means that the waves behind the Yangtze River push the waves ahead."
Kun Yuanzi knew how dangerous the situation he was about to face would be, and that he might not be able to handle it at all. He was still very nervous at first, but after hearing such a joke from Yu Fei, he felt a lot calmer.
Qin Feng's face still had an expression of indifference. A person who was not afraid of life and death would no longer know what fear was.
The three of them walked towards the last factory building and walked to the factory door. Yu Fei just raised his hand and was about to push the door open, but was suddenly stunned because he found that the door of this factory building was actually a brand new stainless steel door. Even the lock on the door is not as rusty as the ones seen before. It has been replaced by a very thick stainless steel lock.
Seeing this situation, Yu Fei couldn't help but feel a little confused: "The door has been changed, and the locks have also been changed. What does that mean?"
Kun Yuanzi frowned and said: "Fushisan is good at setting up traps. Since he does this, I'm afraid something is fishy. Let's take a look around first to see if there are other entrances."
Yu Fei nodded, and the three of them wandered around the factory building.
Unexpectedly, after turning around, they were surprised to find that not only did the factory building not have any holes, but all the windows had been installed with new glass.
"Holy crap, they obviously don't want us to come in," Yu Fei said.
"Hmph, let's break the window and get in," Qin Feng said, raising his hand and striking out with a sword. A sharp sword energy hit the window glass. There was only a "bang" sound, and there were several lines on the glass. There is a small crack, but it is not broken, and the glass is still a complete piece.
This situation was beyond Yu Fei's imagination. He knew how powerful Qin Feng's sword was. Even a copper wall and an iron wall might not be able to block it, but he could not cut open such a piece of glass in front of him.
Yu Fei walked forward with a flashlight and observed carefully. He soon discovered the clues. It turned out to be a piece of bulletproof glass, and its thickness was estimated to be more than ten centimeters. Even a powerful armor-piercing bullet might not be able to penetrate it. Tou, let alone Qin Feng with such a sword.
Yu Fei couldn't help shouting: "Damn it, you are still so strict. Taoist priest, your master can't just do these few tricks. He also claims to be proficient in mechanism skills."
But Kun Yuanzi waved his hand and said seriously: "The Whiskers are not doing this because they are worried about us entering. I'm afraid there is something terrifying inside."
Yu Fei was suddenly startled: "What a terrifying thing? Could it be the roaring monster?"
Kun Yuanzi shook his head: "I don't know either, but it may not be it. The monster's roar shook the sky. If it was really locked in here, I'm afraid the glass would have been shattered long ago."
Although Kun Yuanzi was born in the Tang Dynasty more than a thousand years ago, and there was no glass at that time, he has also learned about the characteristics of glass over the years. He knew that although bulletproof glass is extremely hard and can withstand armor-piercing bullets, If it encounters extremely high-frequency sound waves, it may be shattered, and the monster's roar is louder than thunder, so it is entirely possible to shatter the glass.
After listening to what Kun Yuanzi said, Yu Fei said thoughtfully: "What the Taoist said makes sense, but if it weren't for that monster, there would be something terrifying."
"It's hard to say. Pindao has already said that Fuchen Sanren are good at domesticating spiritual creatures in the world, so birds, beasts, insects, fish, and even demons and monsters are possible," Kun Yuanzi said.
Yu Fei pondered for a while, then raised his head and said, "No matter what's inside, we have to face it sooner or later. Let's talk about it after we go in."
"But this glass is so hard, I'm afraid it won't be so easy to cut. How to get in," Qin Feng said. He didn't expect that his light-containing sword energy could not touch a piece of glass. From his understanding, glass is all Fragile things.
Yu Fei smiled slightly: "Brother Qin, don't worry, I have my own way," as he said that, he summoned the golden dragon from the Nine Heavens Xuanxu Realm.
Yu Fei naturally knew that it would not be easy for the three of them to cut through such a thick bullet-proof glass, and it would take a lot of time, so he wanted Jin Long to try it. After all, Jin Long is the body of the Nine Heavens Divine Dragon, and with its The extremely powerful dragon power would definitely make it much easier.
After the golden dragon flew out of the Nine Heavens Xuanxu Realm, it quickly grew in size. It circled in the air, flew close to the window, and swung its tail suddenly. There was a loud "bang" sound, and the bulletproof glass immediately It was full of cracks. Although the entire piece of glass had not been broken open, it could be seen that the glass had obviously sunk inwards.
After the golden dragon struck twice in the same way, the whole piece of glass shattered with a loud crash. The golden dragon rose into the air, flew into the air, and let out an ear-splitting roar of triumph.
Unexpectedly, just as the golden dragon's groan ended, another shocking roar came, and it seemed to come from the factory building in front of them. Yu Fei and others standing in front of the window were shocked to the core. The sea of qi was churning, and for a moment, his mind almost went blank.
After a while, Yu Fei came back to his senses, but felt a buzzing echo in his ears. When he looked at the golden dragon again, his figure had quickly shrunk, and now he was lying next to Yu Fei's legs, and his body was still shivering. Shivering, it seemed that he was frightened by this sudden roar.
"I... Damn it, what kind of monster is it? It can actually shake the Nine Heavens Divine Dragon with its roar. You must have guessed it right, Taoist Master. It must be that ferocious beast Kui Niu," Yu Fei said in shock.
Kun Yuanzi slowly turned his head, glanced at the golden dragon coiled at Yu Fei's feet, and said seriously: "Aside from Kui Niu, I really can't think of any other divine beasts that can have such power."
"But wasn't Kui Niu already killed by Huangdi Xuanyuan back then? How could it appear here? Could it be that it was resurrected from the dead, and it seemed to have been tamed by Fuchen Sanren," Yu Fei was confused.
Kun Yuanzi shook his head: "I don't even know, maybe the historical facts are different from the records. In any case, we have to be careful."
