gene era

Yan Lie nodded, "It's indeed a problem, it's troublesome. But that's what I just said, dare you take some risks."

"What kind of impostor?"

"In the Mars base, there are aerospace vehicles that can be provided, but they are not free, and a certain amount of collateral is required to use them.

If the battle is damaged, the collateral cannot be taken back.

However, with aerospace vehicles, with my and your capabilities.The harvest of the collateral can be earned back in a day or two.

And the ability to act on the battlefield has greatly increased, you may even go to your teacher, and you also have a certain ability to communicate with the Mars base! "Yan Lie looked at Xu Tui eagerly.

"How much is the collateral?"

"Fifty kilograms of mechanical spirit alloy! Or eighty kilograms of the shell of the fission family."

Xu Tui only thought for half a second before making a decision.

"Done!"

"Okay! Damn, I, a lone ranger, finally have a chance to fly an aerospace vehicle!

Then go now! "

"set off!"

Xu Tui knew about the aerospace vehicle Yan Lie mentioned.

The smallest extraterrestrial combat unit in the technological category, with a maximum crew of three, a maximum speed of Mach [-], and short-distance space travel.

Strong adaptability to harsh environments.

For example, the repulsive flying skateboard that Xu Tui used on Blue Star could theoretically be used on Mars as well.

However, the harsh environment will reduce the life of the thing sharply and cause various uncertainties, and the battery life is even more of a problem.

The cost of aerospace vehicles is very expensive, and there are not many stocks, so students are not rationed for free.

Especially in energy tides and battles, it is extremely vulnerable to damage.

If one is broken, the loss will be huge.

However, students with a certain level of strength can use collateral in exchange for the right to use aerospace vehicles.

The collateral is also a kind of screening for the strength of the students!

Because this thing cannot be popularized, it is only mentioned in the materials of the Mars battlefield.

Most students don't use it.

Occasionally, there are junior seniors who collect enough collateral early in exchange for the short-term use right of an aerospace vehicle.

Of course, if there is damage, it needs to be compensated with collateral.

However, this meeting became the goal of Xu Tui and Yan Lie.

In the next two days, Xu Tui and Yan Lie were almost at full speed.

With the strength of the two of them, at least before the energy tide occurs, these single Mechanical Spirit Race and Fission Race cannot threaten them.

Along the way, Xu Tui and Yan Lie met very few students.

Although Mars is smaller than Blue Star, the land area of ​​Mars is about the same as Blue Star.

The total number of students invested by the six joint districts, including sophomore and junior students, will not exceed 3.

What is the concept of 3 people scattered on Mars?

It takes an average of thousands of square kilometers to have one person!

Unless these people move strategically after the energy tide begins, there is no chance of encountering it.

At the beginning of the journey, Yan Lie still had reservations about his speed, for fear that Xu Tui would not be able to keep up.

But the more he hurried, the more frightened Yan Lie became.

It was very easy for Xu Tui to follow behind him!

With a weight of [-] kilograms, Xu Tui's performance is indeed astonishing, although it has something to do with the weak gravity of Mars.

Then, Yan Lie started to accelerate!

From fifteen kilometers per hour, accelerated to twenty kilometers per hour, and then to 25 kilometers per hour.

This speed is a burden on him on Blue Star, but it is still acceptable on Mars.

Finally, when Yan Lie accelerated to thirty kilometers per hour, he was already out of breath.

As for Xu Tui, he still acted like a normal person.

No red face, no panting!

This made Yan Lie a little depressed.

What the hell, who is the limit system?

Speed ​​up again.

But when he accelerated again, Yan Lie's breathing became unsteady.

"Yan Lie, your breathing is disordered, pay attention to maintain a uniform speed." Xu Tui quickly reminded.

Yan Lie, whose speed had slowed down slightly, looked puzzled, "Why are you so relaxed?"

"I have the mental strength to support it, my load is at least half lighter!"

As soon as Xu Tui's answer came out, Yan Lie almost lost his breath of depression.

It turned out that this was the case, no wonder Xu Tui was so easy!

Although Xu Tui has not yet completed the attempt to fly with the sword, in various attempts, the use of mental power has become more and more flexible.

Two days later, Xu Tui and Yan Lie, who were walking fast, stopped at the same time!

In the distance, there were suddenly dense and ear-piercing explosions.

At this time, several kilometers away, the energy beam and the flames of the artillery fire were clearly visible at this time.

Seeing this, Yan Lie was not surprised but delighted.

"It's the first-line troops stationed on Mars who are cleaning up the area before the energy tide, and it must be the troops stationed outside the Huaxia District.

Generally speaking, the troops stationed at the Mars bases in each joint area will not leave the base for more than [-] kilometers.

Quick, let's join the troops. " Yan Lie said.

"Meeting?" Xu Tui was a little puzzled.

"That's right. The army gives preferential treatment to us students who can independently conduct field operations on Mars.

If we rush over, they may send their mechanized vehicles to take us back to the base to rest, so we don't have to be so tired. " Yan Lie said.

"it is good!"

Xu Tui had absolute confidence in the Huaxia District's troops.

However, he and Yan Lie still slowed down, slightly adjusting their breathing and pace.

The artillery fire in front of us means that we are fighting!

Even massive battles!

Fifteen minutes later, when Yan Lie and Xu Tui climbed up a wind-eroded rock and overlooked the entire battlefield, they were immediately stunned.

Thousands of low-level mechanical spirits of the same color as Mars are rushing towards the outside troops gathered in the position like a tide.

The combat troops couldn't see the number of people at a glance, and a fire blockade formed by intertwined firepower kept strangling these low-level tool spirits.

The low-level mechanical spirits that were continuously smashed by energy weapons or hit the energy core will be torn apart and merged into the ground in an instant.

However, a crippled low-level mechanical spirit beast roared, and the energy brilliance of its body flashed. The limbs of the mechanical spirit clan that wanted to merge into the ground gathered in the crippled mechanical spirit amidst the surge of energy brilliance. on the beast.

In an instant, this low-level mechanical spirit beast was restored to its original state, even stronger!

Then, this low-level mechanical spirit beast took the opportunity to pass through the fire blockade, and drew out its tail whip!

A soldier's extraterrestrial combat uniform was instantly shattered!

The soldier's breathing immediately became extremely rapid.

Without the protection of the extraterrestrial combat uniforms, these ordinary soldiers cannot adapt to the harsh environment of Mars!

The comrades on the side want to rescue.

But the rescue operation caused more mechanical spirit beasts to break through the fire blockade.

In an instant, the extraterrestrial combat uniforms of several soldiers were smashed to pieces!

"Don't worry about me!" The soldier who was shredded into pieces in the extraterrestrial combat uniform uttered his final roar!

Exhausting his last strength, he rolled towards the four mechanical spirit beasts that had just broken through the fire blockade.

The moment he jumped out, he detonated the five plasma infantry mines at once, and the high-energy plasma instantly covered the four mechanical spirit beasts that broke through the blockade.

The fire blockade here was temporarily strengthened, buying time for the other three comrades in arms to rescue!

"What are you still doing, join the battle!"

Xu Tui roared loudly, and rushed to the side of the battlefield first!

Chapter 329 Saving People and Mentality

"This is the battlefield, be careful to be covered by artillery fire!"

Seeing Xu Tui rushing directly towards the battlefield, Yan Lie was a little confused!

But in the next moment, Yan Lie understood Xu Tui's intention.

It's not that Xu Tui's blood boiled after seeing the scene just now!

Instead, he joined the battle sensibly.

Just want to do my part!

Xu retreated to the right side of the battlefield.

It is four to five hundred meters away from the battlefield fire blockade and the wave of low-level mechanical spirit beasts.

This distance, the obvious characteristics of the Blue Star Terran, will not be covered by accidental fire.

However, Xu Tui was rapidly approaching the wave of low-level mechanical spirit beasts from the side.

Yan Lie, who had already seen Xu Tui's intention, quickly chased after Xu Tui like a puff of smoke.

In such a battlefield, his Yan Lie's extreme system is actually powerless.

However, Xu retreat may affect the battle situation.

Then it was very obvious what he needed Yan Lie to do in the battle!

Protect Xu Tui!

Protect Xu Tui from the impact of sporadic low-level mechanical spirit beasts.

In just a few seconds, the distance between Xu Tui and the mechanical spirit beast on the left has been shortened by 300 meters.

At this time, Yan Lie had just caught up to Xu Tui's side.

Yan Lie originally thought that Xu Tui would move on.

But at this moment, Xu Tui's speed suddenly slowed down.

300 meters away, a hill with a diameter of 12 meters suddenly appeared.

Then, as if being pressed by someone, it slammed down to the ground!

boom!

On the ground, the low-level mechanical spirits within 12 meters were immediately emptied.

Their stumps and broken limbs burrowed into the ground one after another and fled far away.

With this blow, at least fifty low-level machine spirits were smashed to pieces!

But in just one second, the 12-meter range that had just been emptied by Xu Tuishan's Zijue was filled again by the wave of mechanical spirits.

The wave of crimson mechanical spirits, like flowing water, wave after wave.
