Amber's sigh is not her own feeling. For every explorer who has just returned from the Sentinel's home port, this feeling of relief is inevitable. Although the Kingdom of God of War can still be regarded as a danger for mortals, it is different from "there is danger" and "the indescribable".

"No matter what, the Kingdom of God of War is still a place where we can control the situation," even Victoria, who always gives people a sense of coldness and alienation, couldn't help but speak after hearing Amber's words, "The things left by the sentry give me completely uncontrollable and unpredictable... I can only say that we still know very little about what the sailor left."

Ms. Windsor Mapel and the Knight Solid, who were greeting everyone here, also came to meet him at this moment. Windsor was the first to come to Daniel with a smile on his face: "I am really relieved to see you return safely. Is this trip going smoothly?"

"There are many discoveries," Daniel nodded calmly, "We have seen other kingdoms of gods, but what is more important than that is that we have uncovered the secret of the 'sentinel' and I will tell you in detail after we go back."

The white dragon Noreta also greeted his friend who had just changed into a human form. The two young dragons rushed into her mother's arms faster than her. The little guys shouted excitedly, hitting Melita's arm and stomach with their heads. The latter had to use his hands and feet to barely deal with this overly enthusiastic "helping": "Okay, okay, don't make a fuss... Everyone misses her mother, right? Do you listen to her mother at home?"

"What you said sounds strange, although it is logically true," White Dragon Noreta came to his friend with a smile, "Look at your expression... the harvest of this journey should not be simple."

"It's not just not simple," Melita pressed the heads of the two young dragons, looked at Gao Wen not far away, and said with a complicated expression. "I recall a little when I exploded my two hearts in one breath. I never got my blood pressure when I went out..."

"We need to return to Cecil City as soon as possible, Knight Solid," on the other side, Gao Wen came to the white knight commander and spoke quickly, while looking up at Victoria next to the snow-like duke. The invisible magic was holding a frozen ice cube. In the crystal clear cube, the entangled vines and two inconspicuous pink and white flowers could be seen. Under the confinement of the magic ice, these plants still remained as frozen at the beginning. "If something needs to be sent back immediately."

"Yes, your majesty," said the high-level combat monk Solid in a deep voice. A low and heavy voice came from the full-coverage white knight's helmet, and then he spoke again, "In addition, there is an emergency report."

Gao Wen was about to hand over the information about the sentry and mention the subsequent exploration plan, but he heard a strange seriousness from the tone of the heavy-armed priest in front of him, and immediately raised his eyebrows: "Emergency?"

"The news came from the Siren Kingdom that our deep-sea allies discovered anomalies in the deep blue net in the water elemental field. They 'salvage' from the magic veins to some man-made creatures with unknown uses and unknown principles. They initially suspected that it might be related to the cultists in the wasteland's demise," said Knight Solid in an extremely serious tone. "Now they have shared the structural diagram and preliminary analysis of that thing with Cecil City, but both Ms. Jenny and His Highness Rebecca have encountered...technical obstacles."

"In the Deep Blue Net Road... the group of siren actually 'salvage' from the Deep Blue Net Road?!" Gao Wen was stunned. First of all, he was shocked by the amazing actions of the group of siren. Then he focused on the second half of the Knights of Solid, "You said that Jenny and Rebecca couldn't understand what the siren were fishing out? What about the other scholars of the Empire?"

Although Jenny and Rebecca are absolute authority in the fields of modern runes and magic, they are still lacking in experience and accumulation. They may not necessarily surpass those traditional wizard scholars in the field of "learning". Faced with the mysterious objects "salvation" by the Siren, perhaps the scholars of the old era who have extensive knowledge can see what the knowledge can be.

However, the Knight Solid just shook his head: "There is no progress. Ms. Hetty even summoned the academic group in the city of San Sunil, but no one had seen that thing... I have never heard of it."

Gao Wen frowned. He couldn't help but think of himself and Carmier and others who had discussed that the "Elf Gemini" in the wasteland might use the power of the cultists to do something in the Deep Blue Net, but he didn't expect that a suspicious clue would emerge so soon. He turned his head to look at Windsor Mapel next to him and the Tifeng scholars led by him, and turned around and frowned to ask the heavy priest in front of him: "Have the relevant information been sent to Tifeng and the Silver Empire?"

"Yes, in accordance with the Alliance Joint Defense Agreement on Major World-class Disasters, we have sent this part of the intelligence to the top leaders of both countries," said Knight Solid nodded, "but..."

"But we have no idea," said Ms. Windsor Mapel, who was on the side, with some concern. "The feedback from the Silver Empire is the same. It is a completely unknown thing to today's mortals, using incomprehensible technology and design ideas. Although the suspicion of this matter is most likely to fall on the cultists in the wasteland, we cannot understand how a group of cultists who seal themselves in the wasteland of Gondor made that thing, and they even mastered the technology of opening the deep blue channel and putting substances into it..."

"It seems that the situation is indeed as we have speculated..." Faced with Ms. Windsor's confusion, Gao Wen only sighed as expected, turned to Carmier and said, "The Sentinel has begun to act."

"Sentinel?" Ms. Windsor was confused when she heard it. She knew the word "Sentinel". In the confidential documents circulated within the alliance recently, the words "Beware of Sentinel" have appeared frequently recently, but she did not know why this disturbing word is related to the wasteland of Gondor. "What is there between this and the wasteland..."

"This is exactly what I mentioned to you just now. The biggest discovery of our trip," Daniel's low and slightly gloomy voice sounded, "Do you still remember the warning of "Beware of the Sentinel"? Now we finally know what this sentence means... An ancient guard left by the Setter has lost control. It penetrated into our world a thousand years ago. After a long dormant, it has now started its operation. The "Elf Gemini" who is currently hiding in the wasteland of Gondor... is faked by this guardian called the "Sentinel"! Now the cultists in the wasteland have become the minions of the sentinel, and they... have mastered the skills of the Setter!"

Windsor Mapel's breathing suddenly accelerated a little, and after a moment she tightened her staff tightly, her face extremely serious: "This matter must be reported to Aldernan immediately!"

"I have to rush back immediately," said Gao Wen, the news brought by Solid Knight made him feel more urgent. "Victoria, if you return to the North to handle affairs, we will need a stable domestic situation next more than ever. Amber and I return to Cecil City, as for Carmire..."

He looked at the ancient magician floating aside and stood by, and nodded after thinking for a moment: "You stay here and continue to preside over the exploration of the Kingdom of God. We need more clues and intelligence, and related research activities cannot be interrupted."

Carmire bent down in the air: "Yes, your majesty."

"Noretta and I are going back to Tallond," Melita walked over from the side, with two young dragons hanging on her body trying to hold her mother's body in a koala-like posture. "What happened in the 'home port' must be known to the leaders Andal and Hragor as soon as possible, and... we must also prepare for a change in the situation."

Gao Wen nodded slowly: "You can set off after a little rest and prepare. Argondore should be waiting for your news."

...

After returning from the Kingdom of God of War, all parties acted on their own. Gao Wen and Amber directly returned to Cecil City on a dragon cavalry vehicle. By the time they arrived, night had begun to cover the city at the foot of the dark mountains, and in the large study of Cecil Palace, Heti had been waiting here for a long time.

The lights from the magic crystal stone dispelled the night that was coming early in winter. The street scene outside the floor-to-ceiling window was filled with lights and the sound of cars and horses. Gao Wen sat back on his most familiar chair. Hetty stood in front of him. The "Empire Housekeeper" had a serious and solemn expression on his face, and the dark circles seemed quite serious.

Gao Wen's eyes couldn't help but stayed on Hedy's dark circles for several seconds.

"The circles of eyes this time are real, ancestors," Hetty sighed helplessly, rubbing his forehead with some fatigue. "I haven't had much rest in the past two days... I spent half of my time talking to Tifeng and the technical officials of the Silver Empire about Deep Blue Net, and I believe they are as anxious as we do."

"So what kind of things did the Siren pick up?" Gao Wen forced his attention away from Hetty's circles and asked solemnly, "I heard that it is a rune device with a very complex structure..."

"Yes, the rune device with a very complex structure looks like a pitch-black cube with a side length of about two meters. The material contains magic crystals, highly purified black stones and several alloys. It has layers of precision structures inside," Hetty nodded, and placed several drawings and materials in his arms on Gao Wen's desk. "This is the information sent by the Siren. The team led by Jenny and Rebecca has extracted and marked the relatively clear structures as much as possible. You can take a look."

Gao Wen took the information and glanced seriously at the dense structural drawings and the text markers around the drawings. He knew that he would definitely not be as good as those real experts in the field of runes, so he did not waste time trying to analyze and calculate the relationship between runes knots and magic guides, but directly tried to judge the secret of this thing from the structural partition inside the "cube".

While he was reading the materials, Hedy's voice continued to come: "At present, we guess that the construction method of these runes is carried out 'layer by layer'. First, the core is created, and then the runes structure is inlaid and drawn on the layers of 'shells'. At the same time, the different 'layers' are connected by precisely placed crystal bolts. There is a shadow of the technology of the Gondor era, but it is limited to the craft part... In addition to crafts, these runes are full of technologies that we cannot understand."

"The technology of the setter." Gao Wen raised his head and looked into Hetty's eyes and said.

"Starting man... I've heard from Amber what you see in the 'Deep Sea'," Hetty said in a solemn tone. "If the 'Elf Gemini' hiding in the wasteland is the sentinel, and these runes are indeed from the hands of those cultists, then the mysterious technology behind these devices will indeed be explained."

"...It is said that the Siren 'salvages' salvaged' more than one such cube from the deep blue network?" Gao Wen asked curiously.

"Yes, as of yesterday afternoon, they had found five of these devices from the Deep Blue Network," Hetty nodded, "and these are just the uncatched, or even undiscovered devices they have successfully captured, probably more."

"What did Siren find out about these devices?"

"They don't have any useful clues," Hetty shook his head, "the Siren itself has a relatively shallow understanding of the magic field, and he doesn't know much about Deep Blue Net, but..."

"but?"

"The Siren Queen Petia mentioned something. Recently, the water elements in the Endless Sea are consciously away from the deep blue veins that have passed through the Endless Sea. Although elemental creatures originally did not like the magic breath in the Deep Blue Net, their recent reactions are particularly obvious and... nervous. The Elemental Lords and Elemental Lords have not explained this, but it seems that they are not deliberately hiding something, but they themselves cannot figure it out."

Gao Wen fell into thought and did not respond to Hetty for a moment. After almost half a minute of contemplation, he suddenly raised his head: "Have Milmina seen these information? She had been in charge of the magical realm, maybe she could see something."

"Not yet," Hetty shook his head, "Ms. Milmina has been studying the secrets behind the magic fluctuations since she returned from the God of War last time. She also submitted a statement of 'Do not disturb' within the Theocratic Council, but I think if you were to go... neither of the two senior consultants would refuse to cooperate."

"Have you devoted yourself to studying the mystery of magic..." Gao Wen murmured softly, but the scene of the "Magic Kingdom" that he saw on the cruise ship appeared in his mind. He felt a lot of emotion for a moment, "She can finally go to the free pursuit of real knowledge now... But I still have to disturb her, after all, I have to send something to Amoen."

Hedy nodded immediately: "Okay, I'll arrange it and go with you."

Gao Wen looked at the "descendants" in front of him who had been following him for several years and couldn't help but smile: "No, as usual, I'll just take Amber with me, you'd better go and have a good sleep."

Hedy immediately spoke up and wanted to say something: "Ancestor, I..."
