Ye Fan didn't know who to choose from the Hero Camp, so he got a three-star unit for all his troops and each of them.

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

Speaking of which, Ye Fan has quite a lot of army units. In addition to tanks, there are many vehicles, food trucks, ambulances, warriors, Xiaolong, Dongfeng Iron Armor, assault armored vehicles, Type 63 towing rocket launchers, etc.

There are more soldiers, including mobilization troops, army soldiers, engineers, military dogs, bazooka, scouts, snipers, flamethrowers, heavy machine guns, mortars, air defense infantry, blasters, etc.

After each army came a three-star unit, Ye Fan decided to check the price first.

He first asked the mobilized soldiers Wang Hu to go there.

Wang Hu walked into the first room, and after entering, the price of being promoted to a hero immediately appeared.

1000 gold!

The cost of mobilizing troops was 100 gold, which was ten times more.

Let the mobilized troops come out, Army soldier Luo Fei went in, and the promotion price was 2,000 gold, which was still ten times.

Military dog ​​Xiaotian goes in, 3,000 gold!

Scout Zhuge Yunxue went in, 5,000 gold!

The engineer went in, 10,000 gold!

When the armored vehicle drove in, the promotion price reached 60,000 gold!

Ye Fan has confirmed that the conditions for upgrading heroes are ten times the cost.

Ye Fan didn't know whether this price was expensive or cheap. It was easy to upgrade and mobilize troops to become a hero, but it would be difficult to upgrade like Wuzhi, and it would be 300,000 gold directly.

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

"Nana, isn't the price of this ten times a bit high? Is the price-performance ratio of heroes that high?"

Nana said, "Sir, take a closer look. The hero unit has a preview after upgrading, which is the image after upgrading. You can see what to do.

Ye Fan asked the troops to enter again and opened Ye Fan to check.

The appearance of the person himself has not changed much. The submachine guns in the mobilized soldiers have changed. The guns have become much larger, and there are grenades, and there are more bulletproof vests on their bodies. They look a bit tough.

And the name has also changed, called the King Mobilization Army.

The army soldiers became even stronger. The light machine gun in their hands turned into a six-cylinder heavy machine gun, with bullet links all over their bodies, which reminded Ye Fan of the Terminator.

The sniper's sniper rifle has become one person tall. Ye Fan believes that it is capable of anti-tank and anti-equipment. It is estimated that it is easy to kill King Kong zombies.

The scouts were similar, and the submachine gun was equipped with grenades and ten high-explosion grenades were hung around their waists. It was estimated that their skills had improved a lot.

There has not been much change in medical soldiers and engineers, after all, their strength is reflected in professional skills.

Xiaotian went in and the previewed body size soared. It was a mutant beast before, but now it feels like a monster.

The 63 rocket launcher has also become much larger, and the originally short rocket launcher has also become large rocket launcher.

Ye Fan, a mechanical type, didn't consider it for the time being. It was too expensive. He only had 30,000 gold in his hand, so he could only do soldier type.

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

As a Red Police Warrior, everyone also desires to have strong combat power, be able to charge for the commander-in-chief and fight bravely to the enemy.

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

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

It can be said that every military has its advantages.

If we consider it in the long run, Ye Fan tends to be engineers.

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

It will be of great help to the crystal research I am currently conducting in full swing.

Previous crystal research once stopped, and it was obvious that the research of ordinary engineers and Samsung Medical Soldiers did not make any breakthroughs.

Ye Fan still remembers that if he wants to improve his own strength, he needs a combat laboratory to improve steadily.

However, the combat laboratory has not been released yet, and I don’t even know when it will be released, so individual Red Alert units need to have high-tech levels.

Even if you are not an engineer, a medical soldier is also a good choice.

Samsung Medical Soldiers are equivalent to professors from medical universities, so what about heroic medical Soldiers?

Will you have the ability to revive the dead?

But now it is wartime and the war is about to begin. It is best to have a hero unit with high combat effectiveness.

Ye Fan adopted the exclusion method.

Both mobilized troops and army soldiers are firepower, but Ye Fan is not short of firepower at present, which is not urgently needed.

There is no urgent need for air defense infantry, and the opponent has not yet shown any air firepower.

The heavy machine gun team does not need to be upgraded for the time being, and the current heavy machine guns are enough.

All that remain are Fire Spitfire, Scout, Bazooka, Sniper, and Military Dog options.

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

Shen Ruihui looked around with his eyes, but Ye Fan did not intend to be the first to improve him.

This kid repeatedly ruined his good deeds, and Ye Fan planned to let him go cool.

Ye Fan thought about it for a while, and before he could tell who to improve the first one, he heard Nana's prompt sound.

"Sir, a supply box has been refreshed thirty kilometers behind you, located on a cliff, and it will last for 48 hours. Please send a scout to collect it."

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

He discovered a problem: the supply box is rarely refreshed in places that he can get directly, and it is a relatively difficult place to reach.

A green spot of light appeared on the radar.

But the radar display was not so clear after all, Ye Fan immediately sent Wuyun to take a look.

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

The supply box was on the cliff, and was sunken, and was wrapped in rattan, so dark clouds could not untie it.

Only humans have flexible fingers.

Scouts are required.

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

"Can you go up and remove the supply box now?"

"Sir, that's very difficult. Our ability is still a little worse now. If we become a hero unit, there will be no problem."

Both of them answered in unison.

Ye Fan sighed helplessly.

He just wanted to make Zhuge Yunxue the first hero unit, but the luck of Shen Ruihui really made Ye Fan envious.

"well!"

Ye Fan sighed to the sky.

The more annoying you, the more you are, the more you are waving in front of you.

This guy is cheaper.

Ye Fan waved at Shen Ruihui: "Come here."

Chen Ruihui came to Ye Fan happily: "Hehe, sir, I knew you were deliberately asking me to wait for a while. You must be testing my patience, right?"

Ye Fan snorted from his nostrils: "Stop talking nonsense, go in quickly."

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

After entering, it was like I was on an operating table, with all kinds of instruments and tubes connected to him.

And his guns were also sent for modification.

This room starts running quickly.

"It is confirmed that this hero unit used scouts, spending 5,000 gold, and is being transformed."

Ye Fan just took the others to wait patiently.

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

As Chen Ruihui walked out of the room, the room was completely closed.

After upgrading to a hero, this room cannot be used any more. There are only six places in this hero camp.

Ye Fan turned his attention to the new Chen Ruihui.

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

25,000 gold is built to build a combat unit. If the strength is not good, Ye Fan will lose a lot.

The freshman Chen Ruihui looks different.
