Lu Yi didn't expect that there was a cave in this fortress, and the deputy castle lord invited Lu Yi to the city lord's mansion Lu Yi thought that the city lord's mansion would be on the island, but he didn't want the two of them to enter a house, and there was a small teleportation array in the room, which teleported the two to a huge hollow space in the underwater part of the island. The deputy castle lord who claimed to be named Hua Zilin introduced Lu Yi as he walked, saying that this place was an ancient relic that he and his brother-in-law, who was also the castle master of this fortress and the early ninth-order monk Zhang Fengyu, had inadvertently discovered in his early years. As soon as the ban of the Sea Clan came out, it aroused great disgust among the Terran monks, and many righteous people began to spontaneously come to the Chaos Sea to find the bad luck of the demons, and there were also those who fished in troubled waters to take advantage of the fire in the Chaos Sea to rob. The two brothers have been running a small but very united force over the years, and as soon as the two discussed, they planned to use this place to establish a foothold for Terran monks to provide convenience for those righteous people. So they left their forces in the hands of the other brothers, and the two of them rushed to the place with a group of elites to build this fortress on the basis of the original ruins.

Soon Lu Yi met Zhang Fengyu with Hua Zilin, Zhang Fengyu was a man with the atmosphere of a superior, he was very polite to Lu Yi, and he did not have the arrogance of a spiritual monk to a spiritual monk at all. After some politeness, the two sides got to the point.

Hua Zilin was a sixth-order formation mage who repaired and perfected the remaining formations of the original ruins and controlled them himself, while Zhang Fengyu was responsible for daily affairs and earning expenses to keep the fortress running. Because it is far away from the mainland, it is inconvenient to raise materials, so it has led to the phenomenon of extremely high prices in the fortress, which also makes their brothers very distressed but helpless. In addition, the fortress's protective array is opened day and night, which is also a huge expense, this is only the normal operation on weekdays, if there is a war, the consumption is bound to be greater, and you have to take precautions and use the usual time to accumulate. In addition, the two brothers also pay close attention to the past monks on weekdays, absorb some like-minded people with lofty ideals, and plan to build this place into a bridgehead against the demons in the future, once the war breaks out, this place will definitely deal a heavy blow to the past demon troops. In order to show determination, this fortress also deliberately gave a very loud name - Demon Castle. It's just that because of the ambiguous relationship between the Sea Clan and the Demon Clan, it has not been officially announced to the public, so as not to provoke the Sea Clan and bring unnecessary trouble.

In the more than 20 years since the establishment of the Demon Castle, it has successfully covered the retreat of the righteous warriors who killed the demons in the chaotic overseas sea many times, and has also absorbed many aspirants who are willing to resist the invasion of the demons. This time, the Sea Clan pursued the six people, in fact, because they had doubts about the Demon Castle, and came to tempt, if the Demon Castle blatantly sheltered the six people, maybe the Sea Clan would have taken action to eradicate the Demon Castle together. Therefore, when the Sea Clan soldiers pressed the border, they were very ambiguous here, neither showing their protection for the six people, nor handing over the six people, so that the Sea Clan did not have a substantial handle. In fact, when the female cultivator of the Sea Clan unexpectedly arrested the young master of Yangchun Fang, Hua Zilin almost couldn't hold it back, but he didn't expect that another master would save them, and also indirectly protected the Demon Castle. And the previous scene of Lu Yi treating the disease and saving people also introduced Lu Yi to the sight of Hua Zilin and Zhang Fengyu, and the two of them felt that Lu Yi should also be a bloody man, so they planned to pull Lu Yi into the gang. The two brothers were very honest, and directly confided their thoughts to Lu Yihe and exposed the core secrets of the Demon Castle to Lu Yi, just with this sincerity, ordinary people would also be moved. But Lu Yi is not an ordinary person, he has his own mission and his own plan, originally this trip to the Chaos Sea was unplanned, he wanted to hurry up and complete the trip to continue his own business, so he refused the two brothers without hesitation.

The reason given by Lu Yi made the two unable to refute, he showed his identity as the deacon of the Alliance Law Enforcement Hall, saying that he came here to go to the Chaos Sea on business, and at the same time, Lu Yi also affirmed the approach of the two brothers, and revealed that in fact, the alliance is also doing the same thing, but it is more concealed and has a larger layout, giving full play to his skillful flickering skills, and the two brothers who bluffed were stunned.

Lu Yi then inquired with their brother about the current situation in the Chaos Overseas Sea, and proposed that he could not stay for a long time in his mission, so he would leave for the open sea immediately. The two brothers saw that they really couldn't keep Lu Yi, so they proposed to exchange spiritual imprints with Lu Yi, keep in touch in the future, exchange information, and help each other.

After Lu Yi exchanged spiritual imprints with the two brothers, he even declined their invitation to invite Lu Yi to have a good drink, he was almost repaired at the moment, although he hadn't drunk for a long time, and his heart was itchy, but he still couldn't help it, because after listening to Hua Zilin's introduction, the current situation in the chaotic overseas sea is not optimistic, so it is better for him to go to the Jiao clan as soon as possible.
