I know how to do vector operations when I travel through time and become a girl

On the empty plain, a seemingly endless border barrier has been established.

On the tall city walls, countless artillery batteries were placed.

Tens of thousands of soldiers are walking neatly and orderly above the border pass.

They each had serious expressions and sharp eyes.

From a distance, you can detect the sense of murderous oppression emanating from his body.

At a glance, you can see that they are not soft bones, but a group of strong soldiers.

Of course, at this time, they are also carrying out the latest order.

That is to guard the heavens and protect the homeland behind you.

This is also their mission as soldiers.

Tianguan is the Federation's ultimate line of defense against alien races.

As night fell, some of the soldiers on patrol also changed their guards.

Under the quiet night sky, this strong sense of atmosphere did not end there.

Under the dark night sky of Western Zhou, there seem to be many dangers and unknowns hidden.

However, the surrounding area of the sky was not affected by the night.

The colorful spiritual power emanating from everywhere made the entire Tianguan look like a galaxy in the night sky.

This powerful spiritual power, surrounding it, seemed to constitute some kind of special formation.

That's right, this is the defensive formation forged by the Federation through the painstaking efforts of several generations in these hundreds of years.

Although this is a defensive formation, is this really the case?

The ethereal spiritual power is not as harmless as it is on the surface...

Once when the alien invasion, the formation was activated.

With the manipulation of all the generals, the spiritual power of the entire Heavenly Pass became more brilliant in this void.

The originally comfortable spiritual power became more active and rioted, and a heavenly spirit air flow went straight to the sky.

In this sky, countless huge vortices of spiritual power were formed.

Under the manipulation of everyone, one after another colored spiritual power full of killing intent shot into the alien race like a laser.

Under this devastating blow, countless alien races were turned into nothingness before they had time to roar.

Among them, there are many who have reached the third-order existence, and even the fourth-order one will hate the northwest if they are not careful.

That is to say, without having time to react, below the fourth order can almost be said to be touched and die.

The formation does have a lot of effect, but the consumption of spirit stones is also great.

Although it can also allow the garrison army to provide spiritual power, it is only a drop in the bucket for this boundless formation.

Of course, the so-called formation is not an invincible enchantment, and it requires everyone to work together to condense a defensive shield.

Therefore, it is mainly necessary to rely on the strength of the army to ensure that the heavenly pass is not lost.

Generally, it will not be used easily, which is such a resource-consuming formation.

It's not that the lives of these soldiers stationed in Tianguan are not valued, but once the formation is activated, it is not so easy to stop.

And the soldiers under their own hands died, in exchange for who does not feel heartache?

If it is not at a critical juncture, the formation will not be used.

This is the principle of the generals of Tianguan.

And the scale of the interracial riot is not particularly large.

Wouldn't it be beautiful to use a psionic cannon with less consumption?

......

Above the pass, a young recruit was chatting with an older soldier.

"Brother Mo, I heard that I have been on the battlefield before!"

"Is it true?"

The recruit who had just arrived seemed to be a little excited in his tone.

I saw this middle-aged veteran known as Lao Mo with a hideous scar on his face. However, although there is this ugly scar, you can vaguely see that there is some handsome face under Lao Mo's scar, presumably he was also very handsome when he was young.

At a glance, you can tell that his story is not simple.

Looking at the enthusiastic recruit in front of him, Lao Mo pursed his lips, and then spoke:

"It is indeed a big fight."

After receiving the veteran's affirmative reply, the recruit became even more excited.

Looking at Lao Mo's expression, there was also a little more respect.

So he continued to speak to Lao Mo:

"Sure enough! Predecessor!

"Which one?"

Unconsciously, the recruit's title for Lao Mo has also changed.

More than a decade ago, there were many wars in the Federation, so the recruits planned to get to the bottom of it.

After all, as a recruit from Z City, of course, I am very interested in these.

At the same time, he is also full of expectations for his longing dream of defending the country for a long time.

Lao Mo looked helplessly at the recruit in front of him and paused, and then spoke:

"Xiao Deng! It was twelve years ago, the defensive battle of Z City. Looking

at the hot-blooded youth in front of him, Lao Mo seemed to see himself in the past.

However, in these brutal wars, the years and experiences have smoothed the edges....

"City Z offensive and defensive battle?"

"Is the senior also from Z City?"

As soon as the recruit Xiao Deng heard that it was the Z City offensive and defensive battle, the curiosity that followed became stronger.

"No, I'm from L City."

"I also went to the battlefield voluntarily back then."

"Then senior, can you tell me your story back then?"

"Back then?"

After saying that, Lao Mo slowly closed his eyes and seemed to be caught in memories.

After a while, he slowly spoke

, "If you want to say something, you have to start talking more than ten years ago."

Then he opened his weather-beaten eyes, looked at Xiao Deng and sighed and continued:

"Back then, I was just like you."

"It's a hot-blooded young man."

"At that time, I was more proud than you."

"To think that going to war is to be able to defend the country!"

"Win merit and fame, but they seem to forget the cruelty and ruthlessness of war."

Immediately pointed to the hideous scar on his face, and warned Xiao Deng:

"War! It's never child's play!

"Just like the origin of my scar!"

"I remember it was the day after the war began."

"Young me, follow my comrades on patrol on the city walls."

"The victory in the war on the first day also seemed to make me relax my guard."

"That joy of victory also made me get carried away."

"In the brutal war that followed, I lost many of my comrades."

Then Lao Mo said to Xiao Deng with an excited expression:

"You know that kind of comrade-in-arms died in front of you!" What kind of feeling is it?

"I still can't forget the look of my comrade before he died..." "

I remember once, maybe I was too tired at that time."

"But none of this can hide my fault!"

"I actually started to snooze while patrolling!"

"So much so that when the alien race came back, he didn't even notice it

..." "The squad leader at that time tried to save me..."

After saying that, Lao Mo closed his eyes in pain, and then said to Xiao Deng again:

"War! It's not child's play!

"Full blood does not bring victory..." "

Only when you have really experienced it, you know the cruelty."

"After that, you follow me, my old bone can still take care of you..."
