"This is the underground city's alarm system. Under normal circumstances, it only sounds when the underground city is facing a life-or-death situation. It's been many years since I heard this sound. I didn't expect that after 62 years, I would hear it again."

Gahn's old face was full of emotion.

"So long ago? Then what does this represent?"

Su Mo asked curiously.

"This represents that Artificial Intelligence·Hei Zhou is now under threat, so it issued an alarm. If I'm not mistaken, the defensive forces of the underground city should all be returning. We should be safe for the time being."

Gahn pondered for a moment and explained.

Hearing Gahn's words, Su Mo and the others temporarily relaxed.

"It's strange, who would be attacking the underground city center?"

Lin Ming was also very puzzled.

"Isn't it your people?"

Gahn asked suspiciously.

"No. By the way, since it's temporarily safe now, Lord Gahn, can we ask you what exactly happened here? Is there any way to leave here?"

Su Mo pondered for a moment and asked.

Gahn looked at Su Mo, sighed, and said, "Since the situation has developed to this point, I won't hide anything from you. I'll tell you everything that happened here in the past."

At this time, the elder behind Gahn said in surprise, "Clan Leader, this is not appropriate, right?"

"Don't say anymore. The guests in front of us are trustworthy. Besides, there's no use in guarding the secrets of the past."

Gahn seemed to have made some decision.

After hearing this, the elders all lowered their heads and remained silent.

"The Hongji Empire was one of the civilizations selected in the first Tian Zhi Bei (Cup of the Heavens). At that time, our civilization was on the verge of collapse. Tian Zhi Bei (Cup of the Heavens) was like a life-saving straw, and we grabbed it without hesitation. We cherished this opportunity and worked hard to develop. Unfortunately, the countries selected in the first Tian Zhi Bei (Cup of the Heavens) were too strong. Even if we worked hard, we were only at the middle level. We faced many threats, not only from monsters but also from other participating civilizations. You must know that plundering resources from similar beings is much easier than plundering from monsters."

Gahn's calm words revealed an extremely cruel reality.

Su Mo and the others remained silent, listening quietly.

"Some people compare the vast forest to a jungle, where the only rule is the law of the jungle. As the weak, we naturally couldn't escape being attacked. In order to cope with the crisis of extinction, we used the power of the whole country to build our home planet into a Zhi Gu (Fortified) planetary fortress and created Artificial Intelligence·Hei Zhou. With the help of Artificial Intelligence, we maximized the strengthening of our national strength. At the same time, we actively moved the planet to the Dunkye Starry Sky to hide. We originally thought that this would be safe, but facts proved that we were too naive. In the days that followed, we were constantly invaded by different kinds of monsters and other civilizations. We engaged in continuous battles for several years, with countless casualties on both sides. That's how the Dunkye Chaotic Burial Starry Sky was formed."

"What happened next?"

Su Mo asked subconsciously.

"There's a saying that even the thickest tortoise shell will be broken one day. Someone released a special virus that disintegrated our Artificial Intelligence·Hei Zhou. At the same time, they besieged the city. In order to survive, we had to take some special measures to forcibly reactivate Artificial Intelligence·Hei Zhou. Under the overall planning of Artificial Intelligence·Hei Zhou, and with us paying an extremely heavy price, we finally defeated the invaders and achieved victory. But before we could even take a breath and welcome the joy of victory, Artificial Intelligence·Hei Zhou went wrong and fell into complete chaos. It mistakenly defined us as invaders, so it turned its guns on us, and then what you see now happened."

Gahn simply revealed the history of the past.

After listening, Su Mo and the others didn't know what to say for a long time.

Then Gahn said, "Actually, it's not impossible to leave the Zhi Gu (Fortified) planetary fortress."

"What way?"

Lin Ming immediately asked.

"There is only one way, and that is to defeat Artificial Intelligence·Hei Zhou and cut off the power system of the entire Zhi Gu (Fortified) planetary fortress. Only then can we leave. But Artificial Intelligence·Hei Zhou is not so easy to defeat. Its central core is hidden very deep, and the defensive forces are very strong. Although you now have a lot of III generation mechas, compared with the other side's forces, they are not even on the same level."

Gahn explained helplessly.

"No matter how difficult or how slim the hope is, we will fight hard."

Qian Chengxue replied without hesitation.

"That's right, we are not afraid of death."

Wittker and the others were very excited. They finally had a glimmer of hope.

At this time, Gahn raised his head and said very seriously, "We can help you and provide great assistance."

"Really? That's great."

Su Mo and the others were also delighted. If they had their help, even if it was just to lead the way, they could avoid many detours.

"But I have a condition."

Gahn suddenly said.

Lin Ming solemnly promised, "Clan Leader Gahn, as long as we can do it, we will never shirk."

"Although this is our home planet, it is no longer habitable and no longer suitable for us to live in. My request is very simple. We will help you defeat Artificial Intelligence·Hei Zhou and help you escape from here. You must accept us. Of course, we will not let you accept us for nothing. We will naturally give corresponding resources."

Gahn made a request that was beyond Lin Ming's expectations.

Lin Ming didn't know how to answer for a while. Of course, it wasn't that Lin Ming didn't agree, but that he didn't have the authority to agree.

Su Mo was also a little tangled. Of course, he was willing, but the problem was that it wasn't up to him to decide.

At this moment, Kalinsa spoke.

"Lord Gahn, it's not that we are unwilling to agree to you, but that we don't have enough authority. But I can solemnly promise that we will do our best to persuade the Black Obsidian to accept you. Even if it's not successful, I can personally promise to provide you with a spaceship to allow you to return to the Star Ring City."

Hearing Kalinsa's words, Lin Ming and Wittker looked at Kalinsa in disbelief.

Kalinsa actually had such confidence to promise. Under normal circumstances, even if Wang Hai came, he might not be able to be so confident.

Of course, Kalinsa didn't just make a promise casually. The reason why she dared to say that was because of Sperd.

The only three people on the entire ship who could make such a decision were Vice President Sperd, who happened to be one of them.

Gahn turned to look at Su Mo and asked calmly, "Mr. Su Mo, I want to ask you a question, is the promise of this lady in front of you valid?"

Su Mo couldn't help but glanced at Kalinsa, then took a deep breath and said, "Valid, I can guarantee it."

After hearing this, Gahn nodded in satisfaction. This was the answer he wanted.
