One of Yunzhou's satellites slowly jumped out of the horizon, revealing half of its bumpy ugly face.

This planet has a total of three moons, but the volume is not large, if the three satellites appear in the same night, it will be a good alien landscape, but unfortunately several of them have different orbital altitudes, the time of revolution is different, after calculation, it is found that the probability of three satellites appearing in the same night sky is three years!

This conclusion disappointed Xia Zhuoyan, who had always had a longing for it.

For the other bridge officers, a few moons, which are so ordinary that they can no longer be ordinary, can no longer arouse everyone's desire to admire, and everyone privately can't help but sigh "It's good to be young", and envy Xia Zhuoyan's carefree and envious.

The two transport ships attached to the engineering unit were extremely efficient, and it took only a few hours to complete the task of laying the space ladder.

There have been countless designs of space ladders in human history, such as fully enclosed orbital elevator shafts or columns leading to the zenith.

The engineering troops brought the simplest one, that is, apart from the upper and lower ends, only the thick rope that ran through the heavens and the earth remained.

Under normal circumstances, the cosmic end of the space ladder should operate at the height of the synchronous orbit, so as to ensure that the cosmic end is always suspended directly above the ground end. However, the diameter and mass of Yunzhou Star are a little larger than that of the Earth, so the height of the synchronous orbit is also a little more than that of the Earth, and the height of the synchronous orbit is about 38,000 kilometers above sea level, and it is simply unrealistic to bring a nearly 40,000-kilometer-long cable from the Earth, and the length of the cable is too high. The cable may be pulled off by its own weight.

The length of the cable used on the Yunzhou star is less than four kilometers, because the speed of the cosmic end is insufficient, and after the ground end is fixed, the cable is as straight as a string, pulling the cosmic end and accelerating continuously, until two days later, the cosmic end is gradually fixed within a certain range under the action of centrifugal force.

The speed of the cosmic end has long exceeded the escape speed of Yunzhou Star, and if the cable is cut at this time, the cosmic end will fly away from Yunzhou Star one hundred percent instead of continuing to float above Yunzhou Star.

This is due both to the insufficient length of the cable and to the tension caused by the centrifugal force to keep the cable straight. So as not to climb the rail train after the funicular is raised. The weight pulls the cable downward, eventually causing the space ladder to crash into the atmosphere.

When everything was ready, the engineering troops began to deliver supplies to the ground.

In the blink of an eye, a week's worth of goods was brought to the ground by rail trains that kept going back and forth between the ground and the air 24 hours a day. A town full of science and technology is gradually taking shape at the foot of the space ladder. It won't be long before it's officially operational.

At the same time, the Ares was not idle. Under Ye Fei's command, the early warning system all over the Yunzhou galaxy took shape, and the farthest remote probe was even arranged a light year away.

Even at the ultra-high speed of one light-year per hour for humans. The unprovoked probe can also send an alarm to the entire galaxy forty to fifty minutes in advance, enough for all personnel in the Yunzhou galaxy to evacuate in time.

March 5, 2214.

After receiving the order to withdraw from the Atlantis star field, the two Skyhawk-class battleships arrived in the Yunzhou system, and the two battleships brought the order to take over the God of War to guard the Yunzhou system.

Until this time, Ye Fei didn't know what his specific mission was, and after successfully leaving Yunzhou Star, Ye Fei contacted the strategic command center as soon as possible, and the communication was directly transferred to Wu Han's personal terminal.

"Chief!"

"Ye Fei, you must have guessed what I was looking for you to do, the mission is coming." Wu Han said straight to the point.

"You give the order, and you make sure to complete the task."

"I'm not busy, I'll pass you back the mission briefing," Wu Han waved his hand, "First of all, I have to explain the current situation to you." ”

Ye Fei's heart jumped: "What's wrong?" ”

Wu Han was amused all of a sudden: "You kid is quite sensitive. ”

Ye Fei smiled: "If something happens, why do you need to introduce the situation to me in person?" You can't send any staff officer to do this job! You are a dignified Minister of Defense, where do you have so much spare time to chat with me, a little captain? ”

"You kid!" Wu Han smiled and shook his head, "Something did happen, let's put it simply, because of your report, we focused on the Atlanteans together, but these few of them were very honest, and they didn't have the slightest abnormal behavior at all, so the General Staff thought that Perian did not leak the situation of human beings, at least it also restricted the spread of news, if the judgment of the General Staff was correct, then it was equivalent to saying that the enslavement of human beings was only Periande's personal behavior, not the meaning of the entire Atlantis Star Kingdom." ”

Ye Fei nodded thoughtfully: "There is indeed such a possibility, but the universe is also adapted to the law of the jungle where the strong enslave the weak, I think that as long as the situation of the enemy is strong and I am weak, there will be no Periander in the future, and the conflict between us and the Atlanteans will only be a matter of time." ”

To paraphrase the old saying that went online hundreds of years ago, that is, Atlantis will not die, and the contradiction between the two sides is the fundamental contradiction of ideology, which cannot be reconciled at all.

Wu Han glanced at Ye Fei with a smile and said, "It seems that the shadow left in your heart is not small, but have you thought about it, although your Aquila was destroyed in the hands of the Atlanteans, you also blew up their two warships, but what about the Mountain Eagle?" Not long ago, the Thunder Eagle unexpectedly encountered the fleet of the Saucer Clan, and the Thunder Eagle and the Saucer Clan circled for three days, until our seven warships arrived, and then completely annihilated the more than 20 flying saucers. ”

Wu Han took a breath when he said this, and then continued: "Until now, we have still not been able to establish any kind of contact with the Disc Clan, and we don't even see any hope of establishing a connection!" But the Atlanteans are different, they look down on us, but at least they don't shout and kill at the first sight. The enemy of the enemy is not necessarily a friend, but at least there is a common interest, I mean, do you understand? ”

Ye Fei nodded with a calm face: "We're going to focus on the Disc Clan, right?" ”

"It's in our interest to do the lesser of two evils, but the Atlanteans aren't left alone." Wu Han sat in a chair and changed into a comfortable position.

Ye Fei immediately said: "Chief, don't worry, I promise to obey the order, you can tell the Lord what I do." ”

Wu Han's eyes suddenly emitted a sharp light: "We want to win over the Atlanteans!" (To be continued......)
