Although he was puzzled in his heart, in order to prevent arousing the suspicion of the battalion commander, Tang Yu did not rush to ask.

Why take such a risk when you can just look it up on the Internet?

After eliminating the vigilance of the Earth Defense Force against himself, Tang Yu walked and his eyes swept around.

The train of the Steel Forest, which had been attacked by the Zerg, was gone, presumably towed away. And those machines that are busy are repairing tracks.

From the staff on the side, I learned that this time the orbit was very seriously damaged by the Zerg. It also took several days for them to be repaired. It should be repaired around this evening. When the time comes, Tang Yu can follow them and take a ride back to Nanhai City, and he will not miss the start of school in time.

Soon, it was noon.

"Little brother."

Just as Tang Yu was sitting boredly on a stone, someone patted him on the shoulder behind him.

Tang Yu turned to look at the comer suspiciously.

This person was no stranger, it was the soldier who had been following the battalion commander all along, similar to a guard.

"Is there something wrong?"

Tang Yu looked at the comer with a puzzled expression.

"You see it's all ordered, I don't think you have eaten yet, have you? Take it. ”

As he spoke, he pulled out two bags from behind him.

Judging by the logo on the bag, it is a pack of spicy jerky, and a pack of compressed biscuits.

"There's nothing else in this wilderness, so let's eat some."

The soldier said in a kind tone.

"Thank you."

Tang Yu smiled at the soldier, and was not polite, and reached out to take it.

"Don't thank me, the battalion commander asked me to bring it to you."

The soldier stretched out his hand and pointed to the figure who was busy directing not far away.

"Battalion commander?"

Tang Yu looked in the direction of his finger with some surprise.

I saw the battalion commander directing the soldiers to move the machine.

"Yes, although the battalion commander usually treats people strictly, he has always been very good to people."

The soldier nodded.

"Listening to the tone, you seem to respect him very much."

Tang Yu turned his head to look at the soldier, and while he was surprised in his heart, he couldn't help but ask.

With his eyes on people, he can naturally see that this soldier respects his battalion commander from the bottom of his heart, not because of his high position, and he respects him on the surface.

"Yes, not only me, but all the soldiers in our battalion regard the battalion commander as an idol."

As he spoke, the soldier turned his head to look at the figure who was busy commanding, his eyes full of adoration.

"Why?"

Tang Yu couldn't help but ask curiously.

A battalion commander who can be so respected by his soldiers and regarded as an idol must have something special about him.

"Half a year ago, when our battalion was fighting with a group of zergs, the battalion commander almost lost his life in order to save an ordinary soldier."

The first sentence alone came to Tang Yu's ears, but it brought a great shock to his heart.

At the same time, he finally understood why this battalion commander could win the respect and support of the soldiers in the whole battalion.

Because, he treats his soldiers as brothers in life and death!

"Okay, you can eat, I don't have much to do."

The soldier spoke, turning to leave.

"Wait."

Tang Yu stopped him.

"Anything else?"

The soldier turned around and asked, confused.

"Actually, I want you to help me check a passenger."

Tang Yu hesitated for a moment and continued.

"At the time, she escaped from the train with me, only to get separated later on the run, and I wonder if she was rescued."

"I can help you with that. Just tell me her name. ”

Hearing this, Tang Yu shook his head helplessly.

"I only met her by chance and didn't know her name."

When the soldier heard this, his brows suddenly furrowed.

"That's a bit of a problem, so let's try."

The soldier turned and walked in the direction where the train was.

Not long after, that is, when Tang Yu finished eating the food he gave, the soldier happened to return.

"Based on the information you provided, there is indeed a passenger who roughly matches your description. Her name is Xia Wenwen and she is seventeen years old. Unfortunately, she, like you before her, is missing and must have been killed. ”

Hearing this, Tang Yu couldn't help but sigh.

……

Time passes inadvertently, and soon, the time of dusk has arrived.

The repair of the tracks was finally completed, and the various machines were carried onto the train.

These machines are not only numerous, but also somewhat heavy. Therefore, it took a lot of time to carry them, and after everything was done, it was already dark.

Then, Tang Yu got on the military train of the Earth Defense Force and embarked on the return journey back to Nanhai City.

When Tang Yu returned to Nanhai City, it was already early in the morning of the next day.

There are still two days left before the start of the university.

Tang Yu got off at the Nanhai Civil Station, while the others continued to take the train to the Nanhai Military Station.

Walking out of the station, Tang Yu came to a bus stop near the station.

According to the description in his memory, Tang Yu got on the 11th bus. The bus ends at his home.

After handing over three earth coins, Tang Yu got into the car and sat down in a window position.

Earth Coin is the unified currency of the new earth and the only currency.

Three hundred years ago, it was first issued when the world government was just being formed. With the official power of various countries, this currency soon replaced the original currency of various countries and circulated in the world.

Tang Yu's gaze looked around.

It has to be said that although it is the same bus, the difference is very large.

The buses of the new earth not only run smoothly and do not make a little noise, but the interior is clean to the spotless, which is many times better than the buses of the original earth.

Retracting his gaze from the car, Tang Yu turned his gaze to the outside of the car, admiring the scenery passing by along the way.

Before he knew it, Tang Yu fell asleep.

By the time he woke up, it was two hours later.

"Where?"

Tang Yu wiped his eyes sleepily, looked at the stop sign on the bus, and it happened that the next stop was the terminal, which meant that he was almost home.

Looking out of the car window, Tang Yu's eyes widened in shock.

In front of him was a huge fifteen-story wall, which stood from both sides to the end of the eye.

"Is this the wall of this world?"

Tang Yu muttered to himself as he looked at it.

To say that this city wall was also built for the Zerg.

The Zerg are known to have a strong ability to maneuver and are extremely agile in their movements. If they break into the city, it will not only be more difficult to eliminate them due to the complex and varied terrain of the city, but also pose a great danger to the civilian population.

Therefore, the countries of the world followed the example of ancient times and built city walls, using walls to enclose the city on all sides, leaving only one entrance and exit on each side. In this way, even if the Zerg attack, because of the city wall, it loses the advantage of flexible action, which is not only easier to deal with, but also better ensures the personal safety of ordinary civilians.
