The "ridge" built with a mixture of special alloys and runes extends from the base of the Sentinel Tower, like some huge roots or some pipes, from the Thunder Hill to the plain. The long-term erosion of magic energy in the wasteland area has stained the creation of this civilization with traces of time. The once smooth alloy shell has become rough and potholes, and the solid runestones blessed by elements are also mottled.

But the damage to the shell is just a manifestation. Inside the "Ring", the ancient magic device is still operating faithfully, maintaining the normal function of the Sentinel Tower. The Silver Empire may have declined, but the creations of the elves are still much more reliable than humans.

A small team of elite steel rangers led by Saldrin to the northern section of the No. 3 "Ring". Gao Wen, Amber, Sonia and the elves magician named Banner walked to the front of the team. They raised their heads and looked at the raised artificial structure on the side of the "Ring". An ancient gate was quietly closed, and the mottled handwriting on the gate was still recognizable: maintenance portal-iii.

"Since the Sentinel Tower was completed and the civilized territory retreated, this gate has never been opened again..." Sonia walked forward and stroked the elf-style relief patterns on the gate with emotion. "There are dozens of Sentinel Towers on the wasteland border, but in the past seven hundred years, only one-third have been effectively maintained and maintained. Some towers are far away from the Silver Empire, and some towers are deeply trapped in extremely polluted areas. These towers that cannot be maintained are completely relying on the automatic repair system of that year to maintain operation."

"Fortunately, most of the things made by the elves are strong and durable," Gao Wen nodded and looked at the mage named Banner. "Master Banner, let's see you next."

Banner, with slender eyebrows and tall and thin figure, nodded. He came to the gate and took out a strangely shaped maple leaf-like metal plate from his body. After stuffing it into a gap in the elf reliefs depicting flowers, plants and trees on the surface of the gate, he began to inject magic into the relief.

The misty floating light flashed over the gate, and the ancient mechanical devices began to operate deep. Around the gate, locks were unlocked in a squeaking manner, but the gate itself remained motionless.

Banner looked at the motionless gate, shrugged, took out an elbow wrench from the tool bag around his waist, and slammed it hard on a lock next to the gate: "Occasionally... these things need a little help."

After a few hits, a noticeable click came from somewhere. The magic door depicting the exquisite relief finally opened smoothly, revealing the dark passage inside.

Amber stared at her eyes: "Hey, I said... yours doesn't match the elegant style of the legendary elves."

"If you look closely, you will find that the arc of the wrench I waved the wrench is a perfect quarter arc and what I have to say, this is elegance," the elf magician put away his tools and looked at Amber. "The world has many wrong impressions of elves, and the labeling is very serious. As a half-elves, you cannot be affected by these wrong impressions, little girl."

Amber rolled her eyes immediately, and Gao Wen was not confused about whether the elf race was elegant or not. He stepped forward and walked towards the gate, reminding the people around him: "Everyone cheered up and there was no living person in this for seven hundred years."

The soldiers crossed the gate and stepped into the main passage inside the "ridge". The moment they entered the passage, the breath of the wasteland was isolated.

Amber immediately sensed this subtle change. She looked back at the direction of the entrance and saw that there was the decaying and twisted demon tide wasteland outside, but it seemed as if there was an invisible barrier blocking the door, and the depressing magic energy aura did not enter the inside of the "ridge".

"The entire Sentinel Tower is protected by a complex protection-filtering system," Sonya noticed the surprise on Amber's face and explained patiently, "This is to prevent the magic tide breath from invading the core of the tower and interfering with the key spell operation inside. This is the main sensor and material circulation pipeline of the tower. Although it is located on the periphery, the protection level is second only to the core area."

"So amazing..." Amber muttered in surprise, raised his eyebrows and looked towards the end of the corridor.

After a few seconds of slowing down, the ancient sensor finally reacted. Magic lamps lit up in the corridor, illuminating the way forward. In this passage that had not been opened for seven centuries, everything seemed to remain the same as when it was completed in the past.

The gray-white ground and walls extend in sight, and the simplicity is dotted with a few elf-style patterns and markers. In addition to magic lamps embedded on the slightly curved roof, you can also see several huge pipes embedded in the building materials in a semi-buried state. The pipes are translucent, and things seem to be constantly surging and transporting inside.

Amber became curious again: "What's in those tubes?"

“There are coolant in the pipe,” said Banner. “In order to control this huge and complex magic tower, a powerful magic mind is placed in the base, which generates a lot of heat during operation. To prevent the core from melting down, we designed a very efficient cooling system. These coolants are only part of the system, with more complex structures in front of it.”

"Wow" Amber dragged his voice and made an exaggerated sigh of praise, while looking at Gao Wen calmly.

Gao Wen was now withdrawing his eyes from the pipes with coolant flowing. His face was calm, but his mind was struggling with the same thoughts as Amber:

The biggest problem with the irradiation light generator is heating.

This cooling system can be used.

"To be honest, I'm very interested in a lot of the technology here," Gao Wen said casually. "Although this tower was built by human countries and elves, we didn't involve its technical part back then... If possible, can you take me to see its heat exchange structure and cooling core later?"

Hearing Gao Wen's words, Banner and Sonia almost subconsciously exchanged a look, and then the latter smiled: "The Sentinel Tower is built and shared by all races, of course there is no problem."

Banner reminded: "However, the magic skills of elves and humans are very different, and the rune structure is very different. This is why almost all the techniques of the Sentinel Tower were in the hands of the Silver Empire back then. It is not that we are unwilling to announce them, but that even if humans come into contact with the runes of elves, they can only imitate them for limited purposes. You should be clear about this."

"Of course, I know, I just look at it," Gao Wen said with a smile, "and we have made good progress in the rune field now. Although humans still cannot release elves' spells, we have mastered some rune translation techniques. The technology in this tower is of some reference value to our side."

"Then please," Banner nodded, "You were one of the builders of these towers back then, and we have no reason to stop you. However, for the purpose of protecting the Silver Empire's property and preventing excessive technology leakage, please do not draw any drawings."

"Thank you very much, that's enough. I'll just take a look at it and refer to your ideas for some magical devices."

Gao Wen expressed his gratitude and then led the team to continue walking forward. Under his calm face, what was hidden was a trace of excitement deep in his heart.

This is the highest technological crystallization of the Silver Empire, everything here... is a treasure!!

Of course, he did not lie about the reasons for entering the tower. He really wanted to figure out what was wrong with these Sentinel Towers, and this was also one of his goals and even missions to participate in the organization of this huge project. But in addition to this formal reason, he was also interested in the elves technology in the Sentinel Tower.

After the fall of the Gondor Empire, these elves mastered the world's most advanced artificial intelligence technology, the most outstanding high-density rune technology, and the most powerful anti-gravity technology!!

Of course, due to the historical legacy of the "Big Elf Schizophrenic Schizophrenic", the elves themselves also have many black boxes to solve in these technologies. Moreover, the elves' magic skills for a long time are almost incomprehensible to humans. The two races have never thought about the possibility of technical communication, but... this is not important.

Mathematics explains the power of each rune and their optimal position.

Sonia and the elf magician named Banner walked quietly beside each other. On the faces of the two elves, Gao Wen could not see too many emotional fluctuations.

They didn't mind Gao Wen's observation of the core structure in this tower, and they didn't mind that their technology fell into the hands of humans.

The reason is only the friendship between the races working together to build the Sentinel Tower seven hundred years ago? Or is it because of their friendship with "Gavin Cecil" himself? Or... they have not realized that the Cecils have actually fully mastered the technology of using rune logic to reorganize elves runes, and have not realized that humans have been able to completely control elves magic, rather than just applying a wind element blessing on the shells?

To be honest, Gao Wen was a little surprised that the other party agreed to his request so happily. He had even prepared to study secretly in the Sentinel Tower, but since the other party had agreed... Gao Wen had no reason to miss such an opportunity.

Although Gauven Cecil seven hundred years ago was knowledgeable, he was more of a military general. He did not have a deep understanding of its technology when building the Sentinel Tower. Human beings were experiencing the Great Recession seven hundred years ago and were also facing the gap of "incomprehensible alien magic". Although he participated in the tower construction project, he also had no contact with the latter's core technology, so today's opportunity is particularly valuable.

The team continues to move towards the core area of ​​the Sentinel Tower base, and every time it advances, Sonia or Banner will ask the team to pause to check the operation of those key devices.

"This is the induction center of the entire No. 3 'Rine'," Banner stopped again when he was halfway through the corridor. He came to a gray-white square pillar with light gold patterns connecting the roof and the floor. He said while taking out the tool. "All the induction centers are connected together. In theory, no matter which of the six 'Rine' is in trouble, the problem should be seen in any induction center..."

While speaking, the mage had already removed a cover plate on the pillar. After the protective cover was removed, a large number of metal pieces overlapping like leaves, with complex magic runes engraved on the surface, appeared in front of everyone.

These metal plates were stacked layer by layer in the column. Banner reached out and waved his hand near the metal plates. Some of the metal plates immediately left their positions and flew into the air. Banner had a serious expression on his face. He used his mind to move objects to control the metal plates to fly past his eyes one by one, and at the same time carefully observed their situation. After observing, he injected magic into other metal plates in the column and sensed their operation.

"…all sensor centers are operating normally, and the sensors on the six 'ridges' are intact," Banner said with a frown, "The signals coming from the wasteland side are also clear."

Sofia asked, "Where is the communication with the Demon Spirit Mind?"
