As we all know, the Monster King Cave is one of the ten forbidden areas. However, most people have only heard of the Monster King Cave, but few know how dangerous it is.

The reason is that the Monster King Cave is located in Jiuyou Mountain, and Jiuyou Mountain is the territory of Jiuyou Holy Land. Without the permission of Jiuyou Holy Land, no one can go in and find out, so naturally no one knows the true face of the Monster King Cave.

But today, everyone learned some exact details about the Demon King Cave from Xin Ruxiong.

"It is impossible to know when the Demon King Cave appeared. The only thing that can be confirmed is that the Demon King Cave leads directly to the demon world. Once it is opened, the demon king and demon lord of the demon world can appear in Dongzhou through the Demon King Cave and set the whole Dongzhou on fire.

Someone couldn't help but ask, "According to what you said, your Nine Nether Holy Land is still a great contributor to the Upper Realm?"

Xin Ruxiong smiled slightly: "I don't dare to be a great hero, but the Nine Nether Holy Land has indeed taken it as its mission to suppress the Monster King Cave for generations. If the Nine Nether Holy Land is gone, the seal of the Monster King Cave will be loosened, and Dongzhou will face a catastrophe."

At this point, Xin Ruxiong suddenly changed the topic and said, "You may not know yet? In fact, the magic skills of the upper domain originated from the demon world. Originally, these skills were only suitable for demons to practice. Later, some cultivators accidentally obtained demon skills and practiced with them. However, demons pay more attention to bloodline talent when practicing, while humans pay more attention to understanding when practicing. Therefore, after these demon skills were practiced by human cultivators, it is inevitable that they are not acclimatized.

"The magic practitioners have made many improvements to the demon skills, and finally formed the magic skills of today."

"What do you mean by saying this?" Guan Shuo asked.

Xin Ruxiong smiled and said, "It's just a demon-like technique, but it has shaped a lineage of demons and spread poison for ten thousand years. If the seal of the Demon King Cave is really lifted, what will happen? Everyone, I don't need to say more, you should be able to guess it, right?"

"Are you threatening us?" Guan Shuo narrowed his eyes slightly and spoke in a cold tone.

Xin Ruxiong said indifferently: "If Saint Guan thinks I am threatening you, then just treat it as a threat. Everyone just needs to know that any sect in Dongzhou can disappear, except the Jiuyou Holy Land."

The scene fell into silence for a moment.

Someone suddenly spoke up, "I don't believe a word he said! What Demon King Cave? Even if the seal is broken, so what? Do you think that with so many cultivators in Dongzhou, they would be afraid of a mere Demon King Cave?"

Xin Ruxiong clapped his hands and laughed, "This brother is very courageous, which is admirable. But saying this does seem ignorant."

"You!" The man couldn't help but get angry.

Lin Xiaoran turned his head and whispered to Di Yu: "Aunt Di, is what this person said true or false?"

Di Yu pondered and said, "I know very little about the legend of the Demon King Cave. However, it is said that the four evil spirits of the Demon Sect that were famous thousands of years ago were said to be demons. The four evil spirits of the Demon Sect each had their own skills passed down through the ages. Although most of them have been lost, many branch versions still exist, which indirectly shaped many demon sects. As for the earlier magic skills, I don't know much about them."

Lin Xiaoran frowned and said, "So, what this Nine Nether Saint said might be true?"

“It’s hard to say, but I did hear someone say before that the Jiuyou Holy Land guards the Jiuyou Mountain. Anyone can cause chaos, but the Jiuyou Holy Land cannot.”

Upon hearing this, Lin Xiaoran couldn't help but fall into deep thought.

Xin Ruxiong looked around and said with a smile: "I know you all feel unfair, but there is nothing we can do. Jiuyou Holy Land was established thousands of years ago and has guarded the Monster King Cave for thousands of years. If the sects behind you are willing to guard the Monster King Cave on behalf of Jiuyou Holy Land and continue to strengthen the seal, then even if you kill us here, what's the harm?"

Everyone was skeptical about Xin Ruxiong's words, and many people immediately asked the elders or protectors who came here with them. Some people who knew a little about the Demon King Cave frowned and remained silent.

Feng Shao looked at this scene with a normal expression, because he had expected what Xin Ruxiong said.

Because among the people present, few people knew the Monster King Cave better than him. And his understanding of the Monster King Cave came from the memory of the Xihe Palace Master.

It is rumored that this Demon King Cave appeared tens of thousands of years ago. It is essentially the intersection of the upper domain and the demon world. Human cultivators can enter the demon world through the Demon King Cave, and demons can also enter the upper domain through the Demon King Cave.

However, if the two sides meet, it is often not a cordial and friendly exchange, but a life-and-death struggle.

The struggle between humans and demons lasted for tens of thousands of years in ancient times. Generally speaking, human cultivators have always been at a disadvantage. After all, there are always demons entering the upper realm, but no human cultivator has ever entered the demon world.

Until thousands of years ago, in a decisive battle between the two sides, the human monks won a decisive victory, drove all the monsters back to the Monster King Cave, and sealed the Monster King Cave. Since then, no trace of monsters can be seen in the upper domain.

The Jiuyou Holy Land was also created at that time.

The skills of the Nine Nether Holy Land are quite strange, more like magic skills than righteous skills, and their style of doing things is completely opposite to that of righteous cultivators. But even so, the Nine Nether Holy Land has always been regarded as a righteous sect, because the Nine Nether Holy Land has guarded the Demon King Cave for generations.

If the Jiuyou Holy Land was regarded as a demonic sect, then it would probably just break the jar and open the seal to allow monsters to enter.

From a certain perspective, the Nine Nether Holy Land can be regarded as using the emperor to control the princes. As long as the Nine Nether Holy Land does not go too far, then all the sects will turn a blind eye to the Nine Nether Holy Land's behavior. This is why Chi Xuan was so arrogant and domineering in the past.

But Chi Xuan forgot that the world feared the Nine Nether Holy Land, but not a mere Holy Son like him. Taking the power behind him as his own strength was the biggest mistake Chi Xuan made.

Everyone fell silent, except Xin Ruxiong, who looked like he had everything under control, smiling and looking very leisurely!

Feng Shao suddenly said: "In that case, then you can go!"

Xin Ruxiong smiled and bowed to Feng Shao: "Brother Feng really knows how to handle current affairs!"

Someone couldn't help but question, "Are we really going to let them go like this? Even if the Jiuyou Holy Land is really guarding the Monster King Cave, we can capture the Jiuyou Holy Son and use him to threaten Tao Yan!"

Feng Shao shook his head and said, "Do you really think that Tao Yan would care about the life and death of a mere Nine Nether Saint? There are few people who can cross the Tribulation Realm, but the Saint Son can be replaced at any time. The importance of this Xin Ruxiong is not yet unique."

The man was speechless.

Xin Ruxiong also smiled slightly and did not refute.

Some people always think that as long as you are important enough, no one will dare to touch you. However, they do not know that if you are not important enough, no one will touch you under certain circumstances.

As for the option of killing Xin Ruxiong to vent their anger, everyone automatically ruled it out. Xin Ruxiong was indeed not very important, but he was at least a leader of the younger generation of the Nine Nether Holy Land. If Tao Yan and others were to fail here today, then the Nine Nether Holy Land would need Xin Ruxiong to take the lead. Without Xin Ruxiong, the Nine Nether Holy Land would inevitably fall into chaos, which would inevitably affect the seal of the Demon King Cave.

Thinking of this, Feng Shao couldn't help but admire Xin Ruxiong's plan.

Seeing that no one objected, Feng Shao continued, "Brother Xin, you should have nothing else to do in Wuling City, right? If you have nothing else to do, please leave immediately!"

Xin Ruxiong didn't hesitate, he bowed to Feng Shao and said with a smile: "In that case, I will take my leave now! We will meet again in the future!"

Feng Shao looked at Xin Ruxiong, and a meaningful smile also appeared on his face: "Brother Xin's ability to calculate makes me admire him. But I wonder if Brother Xin has ever thought that sometimes your calculations will also fall into the calculations of others?"

Xin Ruxiong said nonchalantly: "If that's the case, then it's like meeting a worthy opponent in a game of chess, and it should be a joy in life!"

Feng Shao nodded, said no more, and just said: "Please!"

Xin Ruxiong said nothing more. He turned around and left Wuling City with the people from Jiuyou Holy Land.

Feng Shao set up the Wuling City defense array to allow exit but not entry, so Xin Ruxiong and others walked out of Wuling City effortlessly. When the people from the Jiuyou Holy Land outside the city saw Xin Ruxiong, they hurried forward to greet him and asked about his next plan.

Xin Ruxiong said calmly: "Continue to attack Wuling City until Wuling City is captured!"

"yes!"

After Xin Ruxiong left the city, everyone in the city clearly felt that the Nine Nether Holy Land's offensive had increased a lot. Some people couldn't help but complain: "Even if the Nine Nether Holy Son can't be killed, if he is detained here, at least he can be contained! Now that he has been released, we have no bargaining chips at all!"

Many people looked at Feng Shao in confusion. It was hard to understand why Feng Shao made such an unwise decision.

Feng Shao ignored them, but turned around, handed the brown crystal in his hand to Lin Xiaoran, and said softly: "Ran'er, this city defense formation is temporarily controlled by you."

Lin Xiaoran took the crystal and couldn't help asking, "So what about you, Brother Shao? What are you going to do?"

Feng Shao smiled slightly: "Xin Ruxiong wants to leave the city, but he doesn't know that I also want him to leave the city. If he doesn't leave the city, some things will be difficult to handle."

Everyone was stunned.

Feng Shao said to Zuo Linglan again: "Miss Zuo, please increase the spiritual energy supply to the third level to maintain the operation of the magic circle!"

Zuo Linglan nodded quickly and said, "Yes!"

Having said that, Zuo Linglan hurriedly ran downstairs to take people to adjust the spiritual energy pipeline.

Feng Shao looked up at the sky and said to himself: "I can't be missing in this battle in the sky!"

Everyone was shocked, and before they could react, they saw Feng Shao flying up on his sword, turning into a stream of light and rushing straight towards the battlefield in the sky.

Does Feng Shao actually want to participate in the battle in the Tribulation Realm with his cultivation in the Golden Core Realm?
