"I'll go, it's finally over." Liu Qiyi sat on the ground, and because he was wearing power armor, he didn't feel the cordial love from the earth this time.

"Liu Qi, you should go to school, now, you have 3 days left." Mo Qinghan said.

"Huh? Why? Liu Qi looked confused.

"In 3 days, the preliminaries of the Starship Design Contest will begin, and your mentor will help you sign up, if you don't go, then you will make a lot of money!" Mo Qinghan said.

"Oh? What do you mean by that? Liu Qi asked.

"At that time, you will be famous in the whole school, and this competition is jointly organized by multiple universities, so if you don't go, then the information about your absence will soon be known, plus the additional attributes of your name, hehe~" Mo Qinghan didn't finish his words, but Liu Qi instantly made up a lot of brains.

"Then let's go back with a tight feeling." Liu Qi said, his body shuddering.

"Let's say goodbye to them first." Mo Qinghan proposed.

So, after spending 3 hours making the investigation records, and then saying goodbye to Fan Ge and others, Liu Qi embarked on the journey to Jiangnan again.

Time passed quickly, about 1 day later, Liu Qi came to the first dungeon, Gansu dungeon.

Here, Liu Qi sat on the characteristics of "Shenzhou" - the underground high-speed railway.

Yes, in order to strengthen the communication between the lower cities, the government did not hesitate to spend a lot of money to open up complex transportation lines underground, and the high-speed railway, which used to speed on the surface, turned into a dragon and dived underground, becoming the best choice for long-distance travel.

What's even more terrifying is that these high-speed railways are the black technology proposed in the previous life - vacuum rail trains. Pipelines are built underground, and then the interior is pumped into a near-absolute vacuum with an extractor, and all trains are driven in a vacuum, and the computer is used to seamlessly connect the doors and outer walls when getting on and off the station, so that the trains can travel at supersonic speeds.

"Drop! Student card. With a swipe of his documents, Liu Qi stepped into the platform and saw a beam of light suddenly coming from the originally black tunnel, and the train in the distance arrived at the station and slowly stopped.

In this era, high-speed rail is equivalent to the bus of the old era, a high-speed rail ticket is extremely cheap, basically 1 station and 1 credit, and the information of citizens is calculated synchronously, which is also thanks to the supercomputer matrix "Galaxy" of "Shenzhou", he has achieved 200 million trillion floating point operations per second, throwing off ordinary computers I don't know much.

If it's a good deal, it's Nebula.

"Whew, it's the first time I'm on it, the future high-speed rail." Liu Qi found his place and sat down, the carriage was white and spotless, and the seats were all overhead designed.

Of course, the flight attendants will also come to clean it, but not as often as on the previous high-speed train.

"Good afternoon, distinguished passengers and friends, welcome to the No. 233 Tengfei train, this train, completely banned, please do not smoke on the train, so as not to cause unnecessary trouble, thank you." The Mandarin of the flight attendants is still as standard as ever.

"Sleep, it's coming soon." Liu Qi closed his eyes, Gansu Dungeon is an 8-hour drive from Lin'an Dungeon, and Liu Qi has no electronic products to play, so he can only sleep to kill time.

Eight hours passed quickly, and the train stopped again.

"Passengers and friends, Lin'an Station has arrived, please take your belongings for passengers who get off at Lin'an Station, get off first, and then get on, thank you for your cooperation."

"Ah, I'm back again!" Liu Qi stood at the door and shouted, completely unaware that the people behind him were looking at him with foolish eyes.

"Hurry up, you're blocking the road!" Mo Qinghan reminded.

"Huh? Oh. Only then did Liu Qi realize that there was a team of people behind him. Hurriedly got off the train, and then slipped into the crowd with a puff of smoke, "It's a shame, it's a shame!" ”

Indeed, the long-term solo travel has affected Comrade Liu Qi a lot.

casually called a Didi, and Liu Qi went to Jiangnan Institute of Science and Technology.

In fact, the entire Lin'an underground city is Jiangnan Institute of Science and Technology, the underground city has been transformed into a university city, and the citizens all live on the surface, and the underground has almost completely become a passenger distribution center or some special building places.

"Report!" After many days, Liu Qi returned to class 213 again, a place full of embarrassment.

"Ah, it's classmate Liu Qi, how is it, how are you doing during the holidays?" The counselor said kindly that there is no class now, and the students are all studying on their own, so the counselor is also willing to communicate with Liu Qi.

"It's okay, it's okay overall." Liu Qi said, "The infrastructure project of Jiangnan Star is almost completed, and I also bought a piece of land there, so that you can come to play with me in the future." ”

"Well, it's a good proposal, compared to the grass on the earth except for the projection screen, the environment of Jiangnan Star is much better." The counselor said that although the ecological environment on the earth has experienced thousands of years, it has not yet recovered, and in most places only the tenacious grass can survive.

"Then, welcome Liu Qi back, but Liu Qi, you can't fall behind in class, don't forget to make up for it." The counselor smiled, and the counselor still had a little hearing about what Liu Qi was doing in the Taklamakan Desert.

You know, the skyrocketing planetary engine beam, although it only existed for more than 10 years, but it still made many people see it, and the government used a lot of effort to calm down the turmoil, but many people still discussed it in private, and the country had to say that it was testing new weapons, and the engine had been abandoned, but I don't know how many people believed it.

"Got it, old class, I'll remember." Liu Qi said and walked back to his original actions.

"Coming back?" Li Ziyue sat on the side and asked.

"Hmm." Liu Qi nodded, "Look at your appearance, indulge in learning!" ”

"What do you mean?" Li Ziyue tilted her head.

"I'm getting thinner!" Liu Qi said with a smile.

“……”

“……”

The two stared wide-eyed.

"No, isn't it funny?" Liu Qi asked awkwardly.

"23333333~" Li Ziyue smiled but didn't smile.

"By the way, there's a new classmate in our class!" Li Ziyue diverted this embarrassing topic to blow up.

"Really?" Liu Qi is also happy to transfer, at least in this way, he doesn't have to be embarrassed alone, "What's it called, where is it from, how old is it, male and female, are you in love?" ”

"Damn, you check the account! Ask so detailed! Li Ziyue suddenly glanced at Liu Qi, "That, sitting in the direction of you at 11 o'clock, wearing white, Kang Weijie, seems to be a big guy too." ”

"Yes, this class is full of bigwigs except me." Liu Qi said.

"Hehe~" Li Ziyue didn't say anything, saying: I believe you are a ghost, you are a bad old man, very bad!
