While fighting continued in many areas on the ground, the main expedition team of the expedition also entered the largest ancient human remains on the surface of the planet. Unlike most of the ruins on the planet's surface, this large ruin does not look like a shadow of ancient Chinese or Roman architecture.

The above ground level of the entire building looks more like a Mayan observatory, but unlike the Mayan observatory, which was used for worship to the gods, the size of this relic is much larger, and the length and width of the above-ground part alone are close to 10 kilometers.

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

The underground part resembles a giant ant nest, with an unusually complex structure and densely packed with numerous rooms and halls of various sizes. The Covenant's expedition team has been excavating this site for more than ten years, but only a small part of the underground area has been discovered.

Due to the strong access to most of the underground areas, it is difficult to open even by violent means. In addition, the defense system of the ruins here is still in operation as in the Precursor ruins, protecting the overall structure of the ruins.

As such, all non-human races are still considered unwelcome by the defenses. Any Covenant personnel who attempt to violently enter the depths of the ruins will be attacked by automated defense systems, and all attempts to violently open the ruins arranged by the Covenant have been accompanied by tragic casualties.

Coupled with the fact that the technology system of ancient humans is very different from the Forerunner technology that the Covenant learned, this makes the Covenant's attempt to explore the ruins here a typical thankless action with high risk and low returns.

Therefore, for these reasons, the researchers and authorities of the Star Alliance are not very enthusiastic about exploring here. Until now, more than ten years after the occupation, the exploration of the ruins by the scientific expedition personnel of the Star Alliance is still superficial.

After the expedition captured many research stations on the outskirts of the ruins, they found many records left by the archaeological team and captured many prisoners. But the Covenant's archaeologists were still at a loss when asked about the core of the ruins.

It's obvious. Due to the lack of motivation to explore, they still do not have any substantial knowledge of the underground part of the ruins. Even the Covenant experts, who had been studying for several years, did not explore the depths of the ruins, and the scientific researchers of the expedition team were naturally affected.

Although Shen Chao had great expectations for this operation, many members of the expedition team were not confident in this expedition to explore the ruins. After all, this is the control area of the Star Alliance, and the activity is dangerous, and the exploration window is small.

Compared with. More people hope that Shen Chao can end his exploration here, so that everyone can follow the many known clues and explore more Forerunner ruins. It's safer there, and the first mover is undoubtedly more technological.

Shen Chao naturally knew the ideological tendencies of these team members, and he himself had such thoughts before. According to his original plan, they would indeed explore more Precursor ruins, but his instincts told him that it might be very dangerous to continue exploring other Precursor ruins.

And now, after choosing to explore the ruins of ancient humans, he still can't get rid of this ominous premonition. This made him more vigilant while questioning the veracity of this hunch. Suspect if the source of the danger is more than you anticipate.

Under such worries, Shen Chao, who usually likes to be on the front line of the mission, unusually stayed on the bridge of the Pegasos during this operation, and remotely commanded a qiē operation in space and on the ground from afar.

And after he commanded the mission to take down all the ground targets in Chamhak, the frigate Amber on which the Master Chief was riding finally arrived in the same planetary system. If Yi Qiē goes according to plan, he will soon see Shen Chao again.

After finally arriving at the planetary system where Chamhack was located under the guidance of the guide ship, the Amber was soon told that Shen Chao was waiting for them in this galaxy, and after receiving the news, the Master Chief was finally able to breathe a sigh of relief. I let go of the heavy pressure on my body for a while.

In the past few days, he has been forced into a nervous breakdown by the series of events on board the Amber and the heavy pressure of the mission. Now he has finally reached the destination of his mission. He just wanted to meet Shen Chao quickly and pass on Admiral Hood's words to the other party to complete his task.

Speaking of which, it is necessary to mention what happened to them in the previous few days, shortly after the Master Chief and Kelly "relive the old relationship", the witty Cortana discovered the Master Chief's "cheating" behavior through a series of unusual expressions on both sides.

Although Cortana and Master Chief have never confirmed any emotional relationship, this does not prevent her from being jealous as the girlfriend of the self-proclaimed Master Chief. And "punish" the non-commissioned officer chief by all sorts of uncooperative means.

For example, the remote control turns off the power to the room where the two of them are, intermittently cuts off the water, and plays harsh music when the two of them may be making out...... If it weren't for the heavy task, Cortana would have resorted to some more extreme measures to prevent the two from getting closer, and she even had the idea of a complete strike.

And as to bear the double pressure of tasks and feelings. The Master Chief, who suffers from many disciplines, has more troubles. On the one hand, the reunion with his old love Kelly has allowed him to experience a long-lost physical pleasure in the past few days, allowing him to temporarily let go of the heavy pressure around him.

On the other hand, the naked interaction between Tong Guò and Kelly, he also recognizes his own heart. Although he and Kelly still have a special attraction to each other under the interference of old love, the two have been separated for many years after all.

Over the years, Master Chief and Kelly have both been through a lot of separation, and both of them are no longer the other they remember. Master Chief, in particular, found himself thinking more about Cortana as he rolled the sheets with Kelly.

This puzzled him, he hadn't thought about what his relationship with Cortana was anything other than cooperation, but now he began to realize that Cortana had taken a deep place in his heart, to the point that Kelly and his old love could not be concealed.

Kelly also seems to have noticed the Master Chief's absent-mindedness on the way to roll the sheets, and began to question the Master Chief if he already had someone else in mind on the way to the ship's jump to Chamhak's system.

Under such complex emotional pressure, the Master Chief didn't feel that coming to see Shen Chao was an overly dangerous choice. Although he was quite sure that Shen Chao would definitely be unhappy about his last default, compared to looking back at the problems that Cortana and Kelly had put at him, this little pressure no longer seemed difficult to accept.

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

As an outstanding product of Star Alliance's high-tech technology, this unknown model of infiltration ship has excellent stealth effect, and will hardly release any optoelectronic and thermal signatures. In the case of long-distance observation, almost no device can detect its storage.

Due to the extremely high cost and difficult maintenance, the number of infiltration ships of this type is extremely small. Usually only one or two ships are equipped in a large fleet of more than 1,000 ships. And as pioneers in exploring the human world, they are always the first to reach unfamiliar star fields.

Their regular mission is to probe the UNSC's warship deployments to determine the strategic situation, allowing the Covenant's fleet to choose the best moment to strike based on friend and foe. Occasionally, they will also carry out reverse infiltration missions to prevent the UNSC's fleet from infiltrating the rear sector of the Star Alliance.

As early as the Amber departed from the solar system, the Covenant infiltrator ship, which was on a reconnaissance mission to the solar system, observed it and followed it covertly. It's been nearly a month since the Covenant discovered the solar system, the home of humanity.

Previously, the reason why the Covenant focused on attacking Zhiyuan instead of Earth was because they mistakenly believed that Zhiyuan was the home planet of mankind. Even now, they are not sure how many humans are in the solar system, and whether they are the home planet of mankind.

This was one of the important reasons why they didn't attack immediately, and another reason was that the Covenant also needed some time to recuperate after the previous Great Star War. At the same time, in order to find as many human hiding places as possible, the Covenant sent a large number of reconnaissance teams to track down all the UNSC warships they could find.

The Amber was the only warship they had observed sailing in the solar system, and according to the UNSC communications they had intercepted, it was likely that the Master Chief they called "The Demon" was on this ship's mountain.

And the place where the Master Chief appears has always been a very critical location for UNSC. Therefore, after careful weighing, the Covenant infiltration ship, which did not have any shields and weapons for concealment, cautiously followed.

And because the Amber was in charge of welcoming the Amber before, the ordinary frigates in the two space-time fleets had limited power, and the power of the ship's detection equipment was limited, and the Star Covenant infiltration ship had been maintaining a considerable tracking distance, so on the way here, they had not been able to find the little tail that was following them far away.

Even now, after following the Amber to the system where Chamhack is located, the infiltration ship is still too far away from the space-time fleet with the Pegasus as the core, and neither of them has the ability to detect each other.

Of course, the eventual encounter is inevitable. As the infiltrator followed the Amber as it approached the space-time fleet on the outskirts of Chamhak, they finally discovered each other's sustenance.

In the midst of a burst of surprise caused by the alarm of the detection equipment, the Covenant infiltrator leaked its own storage, and before they could figure out what was going on, a burst of intense artillery fire from the space-time fleet turned the unshielded infiltrator ship into cosmic dust. (To be continued......)
