The biology course in the third grade made Fang Dong gradually realize the differences in this world.

The Zerg, so that the survival of human beings in the interstellar world a thousand years ago was once in danger of the complete extinction of the race.

And their current planet is close to the Insect Domain, only five hours away from the first line of defense of interstellar humans, the North Base Planet Defense Line.

The armed forces of the human race have been balanced against the constant invasion of the Zerg for a thousand years. No one knows if this balance will be interrupted.

Fang Dong surveyed the interstellar map and came out to see. The education star is in the central star field. It's a very safe place. The northern star field is the star field with the longest defense line, the western star field also has a small part of the defense line, and the boundary between the southern star field and the eastern star field is only the area that has no exploration value for the time being.

Fang Dong really studied the biology course seriously, especially when explaining the Zerg, Fang Dong had always been curious about various things.

"It's really disgusting" Sihua found out that Fang Dong was actually watching the recently popular horror TV series "Scattered Zerg" when she was eating lunch.

"Nausea, it's not disgusting, I've been numb in biology class recently" Fang Dong took a bite of nutrients, and she was rated as an outstanding student representative, and she received ten special flavored nutrition gift certificates, and she redeemed a bag of taro-flavored ones this time. It's really delicious. "But this plot is too brain-dead, this actor is not good-looking, not as good as our General Pu."

The little cute girl of the silk flower nodded her head wildly, "Yes, yes, General Pu is handsome and powerful, and I like him the most."

So Fang Dong, who has a huge mental age, frantically talked about General Pu with his little sister, who was really a little sister.

After entering the fourth grade, the course began to become a little more difficult, mainly because the basic formulas of mathematics have increased many different places from the earth in the 21st century, and the calculation methods are also different, and Fang Dong is not easy to learn.

Fortunately, compulsory education in the interstellar era does not need to learn foreign languages, only one language.

When Fang Dong graduated from the fourth grade, the eldest son of the Xi family, Bran, ended his chic days on the education planet by failing to pass the ninth grade. I got a very high diploma. The eighth-grade graduation certificate, although it is a major in ancient Chinese, is still very easy to find a job.

Because the cost of jumping to the North Base Star after graduation and the cost of taking the spaceship home from the North Base Star will need to be paid by himself, so Bran decided to go directly to the work site of the Dry Valve Star, and work for a few months on the main star of the North Star Field, and then come back when he has vacation and spare money.

He worked for a large tutoring institution and made rich people's money, because professional skills such as ancient Chinese could be added to the selection exam. Most of the children of wealthy families choose the ancient Chinese class with more extra points to add chips to their children in the interstellar selection exam, which is absolutely impossible to cheat.

There are also 3,500 interstellar coins per month during the internship period, and it only costs 2,000 interstellar coins to jump from the withered valve star to the nearest North Base star, and the cheapest one to take a spaceship home from the North base is only 100 interstellar coins. Because the previous jump from school to Withered Star was a loan that Bran applied for, and it cost him 3,000 interstellar coins, and he had to pay off the jump ticket and interest in seven months, and he had to repay 500 interstellar coins every month, plus 1,000 yuan per month for rent, and 2,000 yuan on hand, as long as he didn't eat expensive natural food at every meal, he would soon be able to save enough tickets to go back. Bran hadn't been home for four years, as the empire gave students free jump tickets every four years, but accidentally graduated in the second four years. It costs a full 4,800 interstellar coins to jump from Education Star to North Base Star.

After the three-month internship period of Bran, he entered the official period, with a salary of 7,000 yuan per month. It just happened to be a long holiday, which was the day when the Northern Defense Line was established, and the entire Northern Star Field had 196 standard hours off. The current unified timekeeping method is to follow the ancient earth hour. Because the time of day is different on each planet, the holiday will be said to be how many standard hours there are. However, the calendar is unified for each star field, for example, the northern star field is based on the main star time. It just so happens that the time of Bitkos and the Northern Star Field is the same. That is, it is the same time as the education star.

So Bran had a full week off.

It just so happens that everyone is on holiday.

Sihua and Xia Ke plan to travel to the withered valve star, and they are really rich.

Lao Xi thought about it, closed the shop, and took Bran, who had just come back for a day, and his daughter Fang Dong, who had just come back halfway, to the only attraction in Bitcos Star. Near the remnants of the Worm Domain battlefield.

This point was brought up by Fang Dong, because she had been really fascinated by the battle with the Zerg a thousand years ago recently. She was pleasantly surprised to find that among the ten e-books given to her by the teacher last time, there was the most popular personal biography of General Pu Ningbei.

So on the first day of Bran's return, his only partner, Fang Dong, almost ignored him, and only cared about reading novels and biographies.

"Dongdong, you don't call me brother anymore, you still called me brother before I went to compulsory education school." Bran was a big fool, grinning at Fang Dong, who didn't look bad.

"Don't talk to me, you little brat," Fang Dong sat side by side with Bran in the back of the small pickup.

The wind was strong and the sand was blowing everywhere, and the weather was really bad.

It's better to stay at home. My heart was full of remorse.

Lao Xi's driving skills are not high, and he drives to the bumpy sections. I almost didn't give Fang Dong a turn.

Departing in the morning, we drove for about five hours and finally arrived at the so-called ruins site.

There is a small hotel.

The trio opened a family suite. The kind of two rooms and one living room, the twelve-level planet is really the most lacking land, and all houses are built big.

Of course, the room facilities are very poor, and it is not as good as the small room of the old Xijia Fang Dong and there is no air conditioning.

At noon, the three of them lay down for a while and then went to the only scenic spot on the planet, the ruins of the ancient battlefield.

"So that scrap metal is some general's mech?" Fang Dong squinted at the pile of scrap iron that was fenced off.

And then one glance at a large piece of bone "What's that?" Fang Dong pointed.

"That's the teeth of the Zerg." Bran was dying of heat with his hat

"This is too big, this is bigger than my thighs" Fang Dong stretched out his hand and gestured.

Lao Xi didn't know what he was doing, and kept squatting on the ground.

"Dad, what are you doing" Fang Dong looked around at the so-called ancient battlefield, there was really nothing to see.

"I'll see if there are any antiques in this place, pick up one and take it back," said the old man happily.

Fang Dong hurriedly squatted down with bright eyes.

Hibran took off his hat and slapped the wind twice. The head is dizzy, "How can there be, even if there are antiques, others have already picked them up." Let's go back, it's too hot."

Fang Dong and Lao Xi stayed for a long time and their thinking was also assimilated, and the two didn't listen to anything, and rubbed on the ground for a long time.

"What are you doing" A loud voice, as if it had been turned on, almost scared Lao Xi to death, and Fang Dong's voice suddenly appeared.

Lao Xi immediately jumped up and stood up, and Fang Dong was also dizzy and stood up with Lao Xi's legs.

A man in a Union uniform looked at them with a blank expression, and Bran began to explain that they had dropped something and were looking.

The gentleman didn't listen much, just waved them away.

"We've bought tickets to come in, sir," Lao Xi pulled out the crumpled ticket from his pocket. Now that paper is scarce, this ticket will have to be returned when it goes out. "It cost 10 coins."

"Now the army needs to impose martial law in this area, you go to the person in charge of the park to retreat" After speaking, he made a gesture that seemed polite, but it was actually a gesture asking you to get out.

There are not many of them, so BB can only leave here.

How could the person in charge of the park give a refund, the money that was earned with great difficulty.

The old man was so angry that his face was red, "The chief inside told you to give me a refund"

"Then go to the chief and tell me," poverty makes everyone more reasonable.

Of course, it was impossible to go in again, and Bran stopped the angry old joy.

Fang Dong spoke: "Since you refuse to refund the ticket, why don't you tell us why the army is coming this time?"

The person in charge was stunned for a moment, "What else can it be, every time there is an abnormal fluctuation in the insect domain, this place will be under martial law"

When I asked why, the person in charge said that he didn't know.

After being interrupted like this, Lao Xi was not so angry, so he could only admit that he was unlucky, and the three of them went back to the hotel.

In the evening, the three of them cooked and ate the expensive noodles worth 100 universal coins that Bran brought back, Fang Dong was moved to tears, isn't this instant noodles, this is too expensive. Look at the nutrients for only one dollar to eat, these three people are not very full when they eat a pack.

I really wanted to eat another bowl, Fang Dong held the box and cried and drank another sip of nutrients, and finally was full.

Bran went out with Fang Dong at night and ran around a few laps, and when he came back, Lao Xi was already snoring.

The two took the terminal and played two more sets of the most popular interstellar battle game "Poke the Head of the Bug", and then they were unwilling to fall asleep on the first night of the vacation.
