Fortunately, since it was a free enhancement, the system's default option was "Yes". After waiting for a long time without Liu Yifei's consent, the system automatically confirmed the upgrade and enhancement options for all the war puppets under Liu Yifei's command.

At this time, since "most" of Liu Yifei's troops had completed their frontline defense and garrison tasks, they had already arrived in the film's territory. Therefore, this upgrade was not just for Liu Yifei's elite troops.

After the "strengthening" of the mission space, the mercenary names of all Liu Yifei's troops were prefixed with the prefix "Frost Enhanced", and at the same time, the strength of the entire unit was also significantly improved.

Before the fourth-level mission, Liu Yifei had 340 first-level and second-level "big fairies". After the fourth-level trial mission, there were 415 first-level and second-level "frost-enhanced great fairies".

.

After strengthening, the big goblin's long-range hammer-throwing attack becomes an attack with cold damage. In addition to a slight increase in lethality, all enemies hit by the hammer have a 10% chance of being slowed down in the next ten seconds.

10%.

Liu Yifei looked up his mercenary data and saw that it was indeed the case!

Due to the addition of the "Frost Strengthening" talent, all the attacks of the big goblins can be slowed down!

As for long-range attack units, especially long-range attack units like the Great Goblin, which only rely on numbers and have extremely strong individual strength, such an improvement in special effects is simply the best!

Liu Yifei already has 210 second-level and first-level "frost-enhanced gargoyles".

After the gargoyle is strengthened, not only the close attacks will also have special effects of frost, but what is particularly amazing is that when the gargoyle is attacked, it has a certain chance of emitting body-protecting cold air. This body-protecting cold air can not only cause damage to close attackers, but also is even more amazing.

What's more, there is a certain chance of completely freezing the opponent!

Compared with slowness, the level of freezing is much higher~

For example, since the Gargoyles are air force units, they are often tasked with air interceptions, rapid raids, and pursuits.

Although the deceleration effect is good, it cannot stop the enemy's movements. The enemy will kill again when he should, and run away when he should.

But "freeze" is different, but it can completely immobilize enemy units~

Although once attacked, the frozen state will be lifted, but with a little operation, the enemy's attack firepower can be effectively reduced, and it can also give the troops a certain amount of time to adjust, so that they can better surround the enemy and annihilate them.

.....

Other similar ones include the frost-strengthened Iron Man, the frost-strengthened mage, the frost-strengthened alchemist... Even Liu Yifei's latest Snake Girl and Giant Troops also got the benefit~

With the frost special effects, the snake girl is even more terrifying, and the giant...

It's a pity that we still can't attack from a distance~

At this point, Liu Yifei doesn't mind very much, so the evolutionary military merit of a seventh-level creature is as high as 700 points. But for Liu Yifei, smashing a giant with all his strength is not a big problem. If it is really necessary, he can get one that can go far away.

Attacking Titans are also acceptable.

When checking the composition of his own forces, Liu Yifei unexpectedly discovered that at some point, his five small frost and snow catapults had disappeared! They had been replaced by five medium-sized frost and snow catapults!

The basic range of 100 meters instantly becomes 200 meters!

What this brings is definitely a qualitative improvement!

As for the terrifying machine that has turned into a small frost-snow reinforced bed crossbow...

Liu Yifei was completely speechless!

If this guy is used to shoot densely packed ground units, the effect will definitely be more terrifying than a frost and snow catapult!

After this, the system's continuous rewards for Liu Yifei have completely stopped. If it continues, Liu Yifei will really go crazy!

A total of four trial tasks were finally completed. Originally, this was just a small test to test the player's battlefield analysis and commanding abilities. Unexpectedly, Liu Yifei turned it into a regional decisive battle!

Not only was the mission a complete victory, but the key was that Liu Yifei's military strength had expanded to an astonishing level!

The little assassin who has also gone through the fourth ring trial is no match for Liu Yifei's troops even if their troops double in size! And as for any war machinery, the little assassin doesn't even have a single one~

However, Liu Yifei did not tell the little assassin directly about these details, especially the issue of upgrading and strengthening his own troops, because at least he did not feel that there was any need to argue~

So the two adjusted their status and hurried towards the commander's camp. The trial mission was finally completed. But now, due to the delay of the two of them, the fifth ring battle mission has begun. If they don't go

If the commander-in-chief reports, I'm afraid they will miss their first actual combat general mission...

After arriving at the commander's camp, after talking to the guards on the innermost floor with huge golden exclamation marks on their heads, Liu Yifei and the little assassin were indeed qualified to enter the commander's camp!

Even the snake girl NPC who handed over the mission even gave Liu Yifei and the little assassin a small stone tablet each.

You can't tell what material the small stone tablet is made of. It's warm and cool to the touch, and feels as moist as jade, which is incredible.

On Liu Yifei's side, the words "001 Squadron" were engraved in the center of the small stone plate, while on the little assassin's side, it was "002 Squadron". The two of them understood it at a glance. Thinking about it, it should be something similar to an identity plate.

After actually entering the commander's camp, the two of them suddenly discovered that the space inside this thing was actually quite large!

At first, he just thought it was big, but through Liu Yifei's careful comparison, he was convinced that this thing should be a space magic prop!

Because in terms of external volume, it is impossible for this handsome tent to have such a large internal space!

There are five rooms arranged in a fan shape around the door! The middle position is the real tent of the commander's camp, and the remaining four large rooms are small rooms for the staff camp and other auxiliary battlefield commands.

Although Liu Yifei had long heard that the alchemists of the Tower Clan were the ancestors of alchemists who made alchemy and cast spells, he never expected that their methods were so superb! They had even begun to widely use space magic props in wars! Such confidence

And performance is unmatched by other races.

After entering the commander's camp, the two took a quick look and found that there were a guard in each of the five small rooms, and there were a total of ten guards inside!

You can't tell the depth of this guard just by looking at it, but from the analysis of the other party's equipment and attire, Liu Yifei has never seen anything like it before!

However, since there were so many of them, Liu Yifei thought they were ordinary rare combat units, so he didn't take them too seriously and continued to wander around there.

Through Liu Yifei's experiment, he found that the small stone tablet in his hand did not qualify him to enter any of the small rooms in the inner tent. The only one he could stay in was the surrounding "big hall".

The two of them waited here for a while, and an NPC who looked like a high-level NPC general or a mage ran over quickly and clearly, and quickly and clearly conveyed the message to Liu Yifei and the little assassin.

The first true "General's Mission".

Requirements: Disintegrate the enemy's peripheral eyelines and eliminate the enemy's battlefield reconnaissance troops.

Since the enemy wants to build a huge space portal to achieve their ulterior purposes, the enemy sends a large number of reconnaissance troops to roam around their base to constantly check the troop movements on the tower side.

In this way, the enemy can naturally switch from passive defense to active defense and gain more time for the implementation of the final strategic goal!

This is definitely not a good thing for the Tower Clan. Therefore, if you want to break through the enemy's base as soon as possible and prevent the enemy's evolution, the first thing to do is to completely cover the battlefield information so that the enemy loses their eyes and ears to obtain information!

After confirming that they had received the mission, Liu Yifei and the little assassin turned around and left the commander's camp without further delay.

At this time, the entire plot campaign has reached the fifth hour. The time that has passed has happened to increase the military merit rewards obtained by all players during the battle from the basic 10% to 20%. This has been announced to the entire military camp area before, so basically

Every player knows it.

In addition, it can be seen from the content of the task that this is a time-limited enemy-killing mission with no upper limit on killing. As for the time limit... it is naturally the system's default one-hour round.

Within the mission time, the more enemy scouts are killed, the more rewards will be given in the end. This is probably what it means.

"How's it going? What are you going to do, Brother Yun?"

While rushing to the battlefield clerk, the little assassin asked in a low voice.

"Let's bring out all the flying units, form an air regiment, fight on the move, and kill quickly! Divide into three groups. You, me, and Diwei each lead a group of soldiers. Try to divide them into three general directions and kill them along the way. Flying full

We'll move back in half an hour, and we should be able to kill a few more on the way back."

"Then...Brother Yun, didn't you just get the giant and snake girl troops? You don't need such powerful high-level creatures?" the little assassin asked with some pity.

There are so many high-level creatures. In the past, let alone using them at home, they were rarely seen. It is indeed a pity to let them go to waste...

"Then there's nothing we can do~ Being stronger doesn't necessarily mean being good. The area here is huge. If you walk by foot, you won't be able to kill many people in a one-hour mission. It's such a loss. It's better to use mobile troops to kill at a loss of speed!"

"Ah~ What should I do? I can't fly~"

Involuntarily, the little assassin suddenly remembered such a fatal question.

"It's okay. At the beginning, I'll lend you a blood count to make ends meet. After an hour and a half, I'll give you a bone dragon in exchange for it. That's enough~"

For Liu Yifei, this is not the first time he has done something similar. What should he do? He and the little assassin are also familiar with each other~

Not long after, after rushing to the battlefield secretary's office to confirm the "general's attack order", Liu Yifei and the little assassin were allowed to freely mobilize the biological troops under their names in the camp. As the two made their selections, in the next moment,

A large number of combat mercenaries poured out of the open space behind the two of them instantly!

The little assassin's side was fine, there were just a few dozen gargoyles and more than a dozen lantern monsters, but when he turned his head and looked at Liu Yifei...

Nearly three hundred air force units were all mentioned by Liu Yifei!

For a moment, all I could see was a small area of ​​darkness in the military camp!

In an instant, within hundreds of meters, nearly a thousand other Tower Clan players who saw this scene instantly fell into a state of petrification...
Chapter completed!
