The captain of the fast seven had been waiting outside for a long time, and when he saw Ye Han coming out, he immediately saluted: "Chief, I am the captain of the fast seven, Dai Mingxuan." ”

Ye Han replied: "Hello, hehe, let's be polite, it's important to get down to business first." ”

Dai Mingxuan also smiled: "Listen to the chief, Xiao Jiang-"

"Here!" A warrior floated over.

"Send the chief and his brothers back to the dormitory." After Dai Mingxuan finished explaining, he turned his gaze to Ye Han again, "Chief, then I won't accompany you." ”

"It's okay, busy with you." Ye Han waved his hand and gestured to the little soldier surnamed Jiang again, and the group quickly left, and entered the transport ship's living quarters after undergoing strict decontamination procedures.

Ye Han and his team members stayed on Europin for more than half a year, and after getting on the ship, some people were not adapted to the weightless environment.

Ye Han called this a bad idea, so he simply asked Luo Qi to arrange training and adapt to the environment first.

Kuai-7 is the seventh of the fast transport ships, and it only takes half a month to travel between the earth and Europa, and it takes seventeen or eighteen days to die, so there is no need to hibernate in such a short time, otherwise Ye Han would have rushed to hibernate with these monkeys.

Ye Han thought that the fast 7 would be able to depart soon, but he didn't expect that a car of vines could not be loaded with a transport ship at all, this spacecraft stayed in orbit for two days, not only received a large number of carbon fiber vines, but also used the transport boat to send a batch of supply fuel to the low-altitude orbit, so he set off for the return voyage unhurriedly.

After a few days of precipitation, the initial excitement has subsided, but the expectation in my heart is getting stronger and stronger, and the moment the seventh set sail, everyone invariably breathed a sigh of relief.

Time passed day by day in a dull and monotonous flight, and more than ten days passed in a blink of an eye, and the transport ship was getting closer and closer to the earth.

On August 14, 2029, the fast seven began to slow down, and Ye Han was thinking about when he would be able to return to Earth after going back, when the personal computer on his left wrist suddenly shook slightly: "Chief, I'm Dai Mingxuan!" ”

"What's the matter?" Ye Han asked casually.

"I just received a communication from Beiyuezhou, please come to the bridge."

Ye Han was stunned for a moment, and immediately climbed out of the sleeping bag: "I'll be there soon, do you know who is looking for me?" ”

"I don't know...... Communications from the command. Dai Mingxuan said cautiously.

Kuai-7 belongs to the Beiyuezhou Transport Fleet, although the number seems to be independent, it is actually a sub-fleet under the Beiyuezhou Fleet, and Dai Mingxuan has never received a direct communication from the headquarters.

The living area is not big, Ye Han floated into the bridge after a while, and asked Dai Mingxuan, "What's the situation?" ”

"Message from the headquarters, for you." Dai Mingxuan said.

Ye Han had a bad premonition in his heart: "Find me a cabin with no one." ”

"Is the conference room okay?"

"Yes."

"Please come with me, just outside the bridge." Dai Mingxuan personally led the way.

Ye Han asked as he floated out, "How far are we from Beiyue Continent?" How long is the communication delay? ”

Dai Mingxuan said: "Millions of kilometers, with a delay of about ten seconds. ”

The two floated out of the bridge, and Dai Mingxuan sent Ye Han into the conference room not a few meters away, without even entering the door, and returned to the bridge after saying hello.

Don't ask what you shouldn't ask, don't listen to what you shouldn't hear, at the level of others, it's a great secret to reveal a little bit of information casually, and it's best not to even think about it, otherwise you may hear something you shouldn't hear one day.

Ye Han floated into the conference room, waited for the hatch to be closed tightly before turning on the communication equipment, after entering the identity code, the communication interface popped up on the screen, and then entered the password to extract the communication content.

Gao Kai's long-lost face appeared on the screen: "Ye Han, contact the headquarters as soon as you receive the communication, I will wait for you." ”

Something that doesn't say something but asks him to contact the command? Ye Han's bad premonition was even stronger, but he didn't dare to slack off in the slightest, and immediately contacted the headquarters.

Ye Han has been counting seconds since the request was sent, and after twenty-two seconds, the screen flashed and split into two halves, with Gao Kai's old face on the right and Huo Qiang's older face on the left.

As soon as the picture appeared, Gao Kai asked in a pleading tone: "Commander, did you say it yourself or did I come?" ”

"You name it, I add." Huo Qiang said.

"Yes!" Gao Kai agreed, "Ye Han, let's have a video conference, first of all, report the situation, in late June, our aerospace telescope found an alien fleet near Jupiter, and the scale of the fleet is not small, the last time aliens dispatched so many warships, it was the second expedition there in 25 years." ”

"The above attaches great importance to this situation, requiring Tiangong to implement 24-hour monitoring, in early July, we determined that this fleet is accelerating around Jupiter, and it is not yet known where their specific target is, but it is certain that in addition to the Earth is Ganymede, these are these two places."

Jupiter's escape speed is 60 kilometers per second, and if the alien fleet wants to break free from Jupiter's gravity, it must slowly accelerate around Jupiter until the speed reaches the target.

Gao Kai continued: "According to the analysis, the probability that the enemy's first target is Calmede is about 66 percent, and the chance of being the Earth is only 34 percent, but I personally think that Du is a, even if there is only a 1 percent chance, it will be 100 percent when the aliens come." ”

"The situation we are facing at the moment is very serious, and the initial response plan is to ensure the safety of the planet first, and then find a way to keep Europa, including but not limited to armed resistance, sending fleets and other means, if it really can't be saved...... It would rather be ruined than fall into the hands of aliens again. ”

Ye Han's brows were raised high, and a group of *** in his heart galloped by.

He'd been on Ganymede for so long, he could guess a little bit of what was going on above.

When Europa first arrived in Earth's orbit, everyone's thoughts were on guard, but after such a long period of contact and cooperation, humans have obtained a lot of first-hand information on biochemical technology and planetary engines from Callisto, and the acquisition of technology is only part of the harvest.

If Europa is reoccupied by aliens, not only will the source of good technology and raw materials be gone, but the aliens who regain control of Callisto may also manipulate Callisto to get close to the Earth, and at that time, Callisto will once again become the sword of Damocles that threatens the Earth, even if it concentrates the armed forces of all mankind, it cannot be the opponent of Starship.

As expected, Gao Kai continued: "Ye Han, you have been over there for so long, do you have any suggestions, for example, can you send the nuclear bomb to the center of the earth without telling the aliens, as long as the planetary engine is destroyed, even if the aliens snatch Europa back, we are not afraid!" ”
