While the battle in many areas on the ground continued, the main scientific expedition team of the expedition team also entered the largest ancient human remains on the surface of the planet. Unlike most of the remains on the surface of the planet, this large remains do not seem to have the shadow of ancient Chinese or ancient Roman architectural styles.

The style of the entire building above the ground looks more like the Mayan observatory, but it is different from the Mayan observatory used by the Mayans to worship gods. The volume of this ruin is much larger, and the length, width and height of the above ground part are nearly 10 kilometers.

And that's not all. According to the excavation records left by Star Covenant, the underground part of this ruin is much larger than the above ground. If the above ground part of this ruin is equivalent to a super-large three-dimensional city, then the underground part is as big as several urban agglomerations.

The underground part is like a huge ant nest, with an extremely complex structure and densely distributed with many rooms and halls of different sizes. The scientific expedition team of Star Covenant excavated this ruins for more than ten years and only discovered a small part of the underground area.

Since most areas underground have strong access controls, it is difficult to open even if violent means are used. In addition, the defense system of the ruins here is still operating like the ruins of the pioneers, protecting the overall structure of the ruins.

Therefore, all non-human races are still regarded as unwelcome visitors by the defense system. Any attempt to violently enter the depths of the ruins will be attacked by the automatic defense system. All previous attempts to open the ruins of violence arranged by the Covenant are accompanied by tragic casualties.

In addition, the ancient human science and technology system is very different from the pioneer technology of Star Covenant learning, which makes Star Covenant's attempt to explore the ruins here a typical unpleasant action with high risks and low returns.

Therefore, the above reasons, the scientific researchers and the people in power of Star Covenant are not very enthusiastic about exploring here. Until more than ten years after the occupation, the scientific researchers of Star Covenant still explored the ruins here.

After the expedition team captured many scientific research stations outside the ruins, they discovered many records left by the archaeological team and captured many prisoners. However, these archaeological experts from the Star Covenant still looked confused when asked about the core area of ​​the ruins.

It is obvious that due to insufficient exploration motivation, they still have no substantial understanding of the underground part of the ruins here. Even the Star Covenant experts who have been studying for several years have not explored the depths of the ruins, and the scientific researchers of the expedition team were naturally affected.

Although Shen Chao has great expectations for this action, many members of the expedition team are not confident about this ruins exploration operation. After all, this is the control area of ​​the Star Covenant, with high risk of activities and small exploration windows.

In contrast, more people hope that Shen Chao can end the exploration here as soon as possible so that everyone can follow the many known clues to explore more ruins of pioneers. It is safer there, and the technical level of pioneers is undoubtedly higher.

Shen Chao naturally knew the ideological tendencies of these team members, and he had such ideas before. According to the original plan he formulated, they would indeed explore more pioneer ruins, but his intuition told him that continuing to explore other pioneer ruins may lead to huge dangers.

Now, after choosing to explore ancient human remains, he still failed to get rid of this ominous premonition. This made him more alert while questioning the authenticity of this premonition. He doubted whether the source of the danger exceeded his expectations.

With such concerns, Chen Chao, who usually likes to visit the front line of the mission, stayed abnormally in this operation on the bridge on the Pergasos, and commanded all actions in space and on the ground from a distance.

After he commanded the mission to capture all the ground targets of Chamhak, the Amber frigate that the Chief of Staff finally arrived at the same planetary system. If everything goes according to the plan, he will soon see Shen Chao again.

After finally reaching the planetary system where Chamhak is located under the guidance of the guide ship, Amber was soon told that Shen Chao was waiting for them in this galaxy. After receiving the news, the Chief Sgt. He finally breathed a sigh of relief and temporarily put down the heavy pressure on his body.

In the past few days, he has been a little nervous because of a series of events and heavy task pressures on the Amber. Now he has finally reached the destination of his mission. He just wants to see Chen Chao quickly and hand over the words of Admiral Hood to the other party to complete his mission.

Speaking of this, we must mention their previous encounters a few days ago. Shortly after the Chief of Staff and Kelly "re-reconcilable relationship", the witty Cortana discovered the Chief of Staff's "infidelity" through a series of abnormal performances between the two sides.

Although there has never been any emotional relationship between Cortana and the Chief Secretary, this did not affect her being jealous as the self-proclaimed Chief Secretary’s girlfriend. She also "punished" the Chief Secretary with various uncooperative means.

For example, remote control terminates power supply in the room where they are, intermittent water outages, and plays harsh music when they may make out... If it weren't for the heavy task, Cortana would have used some more extreme measures to prevent the two from getting close, and she even had the idea of ​​going out completely.

As a chief magistrate who is under the dual pressure of tasks and emotions and is subject to many savages, he has more troubles. On the one hand, the reunion with his old love Kelly has allowed him to experience the long-lost physiological enjoyment in the past few days, allowing him to temporarily put down the heavy pressure around him.

On the other hand, through the interaction with Kelly, he also realized his heart. Although he and Kelly still had a special order of attracting each other under the interference of old love, the two have been separated for many years after all.

Over the years, Chief Chief and Kelly have experienced a lot on the way apart, and both of them are no longer the other person's memories. Especially Chief Chief, he found that when he was rolling the sheets with Kelly, he thought that more of it was Cortana.

This confused him himself. He had never thought about what the relationship between him and Cortana was except for cooperation, but now he began to realize that Cortana had occupied a very deep position in his heart, to the point where Kelly and his old love could not be concealed.

Kelly seemed to have found the Chief of Staff absent-minded while rolling the sheets. On the way to the spacecraft jumping to the galaxy where Chamhak was, he began to question the Chief of Staff if there was already someone else in his heart.

Under such complex emotional pressure, the Chief of Staff did not think it was an overly dangerous choice to meet Chen Chao. Although he was quite sure that Chen Chao would be unhappy with his last breach of contract, compared to looking back at the problems that Cortana and Kelly put on him, this pressure no longer seemed unacceptable.

While the Chief of Staff was preparing to land on Pergasos, in a dark space four astronomical units away from the Amber, a streamlined Covenant infiltration ship was watching the whereabouts of the Amber he was riding from afar.

As an outstanding product of Star Covenant High-tech, this unknown model of infiltration ship has excellent stealth effect and will hardly release any photoelectric and thermal signals. Under long-distance observation, almost no equipment can detect its existence.

Due to the extremely high cost and difficulty in maintaining, the number of infiltration ships of this type is very small. Usually, only one or two equipment is available in a large fleet with a number of more than 1,000 warships. As pioneers in exploring the human world, they are always the first to reach the strange star domain.

Their routine task is to explore the deployment of Unsc's warships, thereby determining the strategic situation, so that the Covenant's fleet can choose the best attack moment based on the comparison between enemies and us. Occasionally, they will also perform reverse osmosis tasks to prevent the Unsc's fleet from infiltrating into the rear star area of ​​the Covenant.

As early as the Amber set out from the solar system, the Covenant infiltration ship, which was performing a reconnaissance mission in the solar system, observed it and followed in seclusion. The Covenant discovered that the human nest, the solar system, had been around for nearly a month.

The reason why the Star Alliance concentrated its efforts to attack the Zhiyuan Star instead of the Earth was because they mistakenly thought that the Zhiyuan Star was the parent star of human beings. Even now, they are not sure how many humans are in the solar system and whether they are the parent star of human beings.

This is also one of the important reasons why they did not launch an attack immediately. Another reason is that the Covenant also needed rest time after the previous Zhiyuan Star Wars. At the same time, in order to find as many places as possible for humans to hide, the Covenant sent a large number of reconnaissance troops to track all the unsc battleships they could find.

The Amber was the only warship they observed in the solar system to sail, and according to the communications of the Unsc they intercepted, the Chief of the Master, who they called the "demon", was probably on the mountain of this ship.

The place where the Chief Chief appeared has always been a very critical place for Unsc. Therefore, after careful consideration, this Star Covenant infiltration ship, which did not install any shields or weapons, followed carefully.

Since the two ordinary frigates in the space-time fleets were previously responsible for welcoming the Amber, the power of the carrier-based detection equipment was limited, and the Star Covenant infiltration ship had always maintained a considerable tracking distance, they had never been able to find the little tail following behind them on the way.

Even now, after following the Amber to the galaxy where Chamhak is located, this infiltration ship is still too far away from the space-time fleet with Pergasus as the core, and neither of them discovers each other's abilities.

Of course, the final encounter is inevitable. While the infiltration ship followed the Amber to the space-time fleet outside Chamhak, they finally discovered the other party's existence.

Amid the surprise caused by the alarm from the detection equipment, the Covenant infiltration ship exposed its existence. Before they could figure out what was going on, a dense artillery fire from the space-time fleet turned the shieldless infiltration ship into cosmic dust. (To be continued...)
