Ye Fan didn't know who the hero battalion chosen, so he got a three-star unit for each of the various types of troops under his command.

This is the Army Hero Battalion, which can only be used to promote the Army.

Speaking of Ye Fan's army units, there are really a lot of them, in addition to tanks, there are many vehicles in machinery alone, such as dining cars, ambulances, warriors, dragons, Dongfeng iron armor, assault armored vehicles, Type 63 towed rocket artillery, etc.

And there are even more soldier units, mobilizers, army soldiers, engineers, military dogs, bazookas, scouts, snipers, flamethrowers, heavy machine guns, mortars, anti-aircraft infantry, demolitionists, and so on.

Each class came with a three-star unit, and Ye Fan decided to take a look at the price first.

He first let the mobilized soldier Wang Hu pass.

Wang Hu walked into the first room, and after entering, the price of promoting heroes immediately appeared.

1000 gold!

The cost of the mobilization was 100 gold, which was a tenfold increase.

Let the mobilized soldiers come out, the army soldier Luo Fei flew in, and the promotion price was 2,000 gold, which was still ten times.

The military dog roared into the sky, 3000 gold!

Scout Zhuge Yunxue enters, 5,000 gold!

Engineer in, 10,000 gold!

The armored car drove in, and the promotion price reached 60,000 gold!

Ye Fan has already determined that the promotion conditions of heroes are ten times the cost.

Ye Fan doesn't know whether this price is expensive or cheap, it is easy to upgrade the mobilized soldiers to become heroes, but if you want to upgrade Wuzhi, it will be difficult, and it is directly 300,000 gold.

The tank also needs 200,000 to upgrade, which is too expensive.

"Nana, isn't this ten times the price a bit high, is the hero's cost performance so high?"

Nana spoke: "Sir, take a closer look, the hero unit has an upgraded preview, it is the upgraded image, you can see and decide what to do."

Ye Fan let the troops in again and opened Ye Fan to check.

The appearance of the person itself has not changed, the submachine gun in the hands of the mobilized soldier has changed, the gun is much larger, and the grenade has been added, and there are more body armor on the body, which looks very strong.

And the name has also changed, called the King Mobilizer.

And the army soldier was even stronger, the light machine gun in his hand became a six-barrel heavy machine gun, and his whole body was full of bullet chains, which reminded Ye Fan of the Terminator.

The sniper's sniper rifle has become one person taller, and it is said that it can be anti-tank and anti-equipment Ye Fan believes that it is estimated that it is easy to snipe King Kong zombies.

The scout is about the same, the submachine gun is also loaded with grenades, and ten high-explosive grenades are hung from his waist, and it is estimated that his skills have also improved a lot.

The medical corps and engineers have not changed much, after all, their strength is reflected in their expertise.

Roaring Heaven entered, and the size of the preview skyrocketed, it was a mutant beast before, and now it feels like a demonic beast.

The 63 rocket launcher has also become much larger, and those originally short rocket launchers have also become large rocket launchers.

Ye Fan of the mechanical class is not considered for the time being, it is too expensive, he only has 30,000 gold in his hand now, and he can only get the soldier class.

When Ye Fan decided to be the first to upgrade the soldiers, he clearly saw the desire in the eyes of these three-star soldiers.

As Red Alert soldiers, everyone also aspires to have strong combat power, to be able to charge into battle for the commander-in-chief and fight bravely to kill the enemy.

Strong combat power requires strong strength, and heroes are the best way to advance.

Ye Fan looked around, and he was a little embarrassed about who was the first.

It can be said that each class has the advantage of each class.

If we think about the long run, Ye Fan tends to be an engineer.

When an engineer becomes a hero, he may become a scientist.

It will be of great help to the crystal research that I am currently working on.

Previously, crystal research came to a halt, and apparently there was no breakthrough in the research of ordinary engineers and Samsung medics.

Ye Fan still remembered that if he wanted to improve his own strength, he needed a combat laboratory to improve steadily.

But at present, the combat laboratory has not yet been released, and it is not even known when it will be released, so it requires the individual red police unit to have a high-tech level.

Even if you're not an engineer, a medic is a great choice.

A three-star medic is equal to a professor at a medical university, so what about a heroic medic?

Will it have the ability to come back to life?

But now is wartime, the big war is about to start, and it is better to have hero units with high combat effectiveness.

Ye Fan used the method of elimination.

Both mobilized soldiers and army soldiers are boosted by firepower, but Ye Fan's current firepower is not lacking, which is not urgently needed.

The anti-aircraft infantry is also not urgently needed, and the opposing side has not yet appeared in the air.

The heavy machine gun crew does not need to be upgraded for the time being, and the current heavy machine gun is enough.

The rest are Pyro, Scout, Bazooka, Sniper, and Military Dog.

There were five people in front of Ye Fan, bazooka warrior Su Mo, sniper Zhao Ming, scout Zhuge Yunxue, flamethrower warrior Wang Aiyu, and military dog Roaring Sky.

Shen Ruihui watched from the side, but Ye Fan didn't plan to be the first to promote him.

This kid has repeatedly spoiled his own good deeds, and Ye Fan plans to let him cool off.

Ye Fan thought about it for a while, and before he could say who would be the first to promote, he heard Nana's prompt tone.

"Sir, thirty kilometers from the Khing'an Mountains behind you has refreshed a supply crate, located on a cliff, which will be kept for 48 hours, please send a scout to collect it. ”

Ye Fan was stunned for a moment, and actually refreshed the supply box on top of the cliff!

He found a problem, the supply crates were rarely refreshed in places where he could get them directly, and they were relatively difficult to reach.

A green spot of light appeared on the radar.

But the radar showed that it was not so clear after all, and Ye Fan immediately sent the dark clouds over to take a look.

The perspective switched to that of the dark clouds, and the guy flew towards the Xing'an Mountains at an extremely high speed, arriving ten minutes later.

The crates were on the cliffs, and they were sunken in, and they were entwined with rattans, and the clouds could not unravel them.

Only the nimble fingers of a human can do it.

Scouts are a must.

Ye Fan looked at Zhuge Yunxue and looked at Shen Ruihui on the side.

"Can you go up and take down the crates now?"

"Sir, that's difficult, we're still a little worse off now, and it's no problem if we become a hero unit. ”

Both men replied in unison.

Ye Fan sighed helplessly.

He just had the intention to make Zhuge Yunxue the first hero unit, but Shen Ruihui's luck really made Ye Fan envious.

"Alas!"

Ye Fan looked up to the sky and sighed.

The more annoying anyone is, the more they are dangling in front of their eyes.

Cheap this kid.

Ye Fan beckoned to Shen Ruihui: "Come here." ”

Shen Ruihui came to Ye Fan upside down: "Hehe, sir, I knew that you deliberately asked me to wait for a while, you must be testing my patience, right?"

Ye Fan snorted from his nostrils: "Stop talking nonsense, come in." ”

Shen Ruihui was the first to walk into the hero camp.

After entering, it was as if he had been on an operating table, and all kinds of instruments and tubes were connected to his body.

And his guns were all sent over for modification.

The room began to run rapidly.

"It was determined that this hero unit used the Scout, and it cost 5,000 gold to transform the ...... ”

Ye Fan took the others and waited patiently.

About half an hour later, Shen Ruihui's transformation was completed.

As Shen Ruihui walked out of this room, this room was also completely closed.

If a hero is promoted, this room can no longer be used, and there are only six places in this hero camp.

Ye Fan set his sights on the newborn Shen Ruihui.

This is not 5,000 gold can be calculated, and the room itself is worth 20,000 gold.

25,000 gold to build a combat unit, if the strength is not good, Ye Fanke will lose a lot.

The newborn Shen Ruihui looks different.

"Sir, heroic scout Shen Ruihui reports to you!"

"Tell me about you!"

"Yes, sir, my basic physical fitness has been improved fivefold, and I have been transformed by the black technology of the Red Police, and the gun behind me has five grenades, and the ammunition of the gun has reached 1,500 rounds! My fighting skills, mobility, reconnaissance and counter-reconnaissance skills have all been greatly improved..... ”

Ye Fan waved his hand, in fact, the scout class is a mediocre class.

All abilities are good, but none of them are top-notch.

Sniping is not as good as a professional sniper, and firepower is not as good as heavy machine guns and bazookas.

But just because he can do anything, he is a versatile class.

But these are not the most important things, Ye Fan just wants to see if Shen Ruihui's explosive luck is ineffective.

"Needless to say, I gave you the first hero unit, it's up to you to get me the good stuff of the supply box, now go and collect the supply box back. ”

"Yes!

Shen Ruihui ran away happily.

With the plane, it's a lot easier to gather supply boxes.

Ye Fan asked Bi Jinbang to fly the plane and sent Shen Ruihui directly to the top of that mountain.

A few minutes later, Shen Ruihui got off the plane and took out the scout's special flying catch.

Caught in the crack in the stone at the top of the mountain, then tied to his waist, he went down the mountain wall.

The mountain walls are undulating and undulating, and non-super scouts simply can't reach them.

Ye Fan paid attention to Shen Ruihui's actions throughout the whole process, he wanted to see if this kid was really so lucky.

Don't talk about good luck, if you have bad luck, then Ye Fan has a lot of good work waiting for him to do.

Even Ye Fan thought about it, ordinary supply boxes are not good, they must be good goods.

This is not revenge, because it involves Ye Fan's lifelong happiness.

Shen Ruihui didn't think about this at all, and followed the rope to the mountain wall.

He quickly untied the vines outside, and then pulled out the supply crate.

I got a rope and tied it to my body, and I completed the task.

Just go back to the helicopter and go back to give Ye Fan an errand.

Just as he was about to leave, Shen Ruihui suddenly lowered his head, and then reported directly to Ye Fan in the system.

"Sir, there's another box in this little depression, should I take it out together?"
