Lan Xuanyu looked at the military mechs in the distance, and there were at least thousands of mechs standing on top of the fortress. All of them are purple-level mechas, not the ordinary military's yellow-level mechas. This is obviously the elite mech division of the Federation.

Strangely enough, none of these mechs are equipped with ranged attack weapons, but instead use knives. A unified large war knife, that is a high-frequency concussion knife. It is capable of generating a powerful cutting force in an instant.

Among these mechas, there are also black-level mechas. Apparently an officer in the mecha division.

A low rumbling sound gradually appeared in his hearing, and Lan Xuanyu fixed his eyes on the distance. In the distance, there were faint clouds of dust, and the earth was trembling, as if an invisible beast was crushing towards them.

In the sky, the Flying Source Dragon first appeared in the field of vision, and hundreds of huge Flying Source Dragons hovered in the air. It's the kind they saw when their spaceship landed.

Then Lan Xuanyu saw the huge source dragon that was just glaring at them and almost sucking them over.

Its stature was too tall, and its terrifying body was too conspicuous to appear in the plains, and a large number of source dragons rushed out in front of it, without pause, and came straight in the direction of the fortress.

"The shield will block the source dragons, but it will also put some into the shield, and then you can take action and cooperate with the military to attack them. Do not use thermal weapons as much as possible to ensure that the Dragon Source Crystal will not be damaged. Do you understand?" Yan Ruoting turned her head to Lan Xuanyu and said.

Lan Xuanyu's heart moved. He suddenly came to his senses, why didn't the Longyuan base take the initiative to attack. Since this beast tide is once every few months, it seems that it is also an opportunity for the military to harvest the Dragon Source Crystal. It's no wonder that all mecha are equipped with war knives, just to hunt the source dragon and obtain the dragon source crystal.

Once a few months, it is enough for the military to obtain a lot of Dragon Source Crystals. And their Heaven Fighters performing such a task is nothing more than icing on the cake. It seems that this mission itself is just a kind of training for the Heaven Fighters.

His guess was correct, in fact, the tasks below the third level included the third level, which was more for the Heaven Fighters to experience and help them grow, and the danger was relatively small.

When you reach the fourth level and above, the difficulty will increase significantly, and it is the true meaning of the Heaven Fighter mission.

Correspondingly, those who fight the heavens below the third level are also in a state of cultivation, and naturally they will not be taken very seriously. And the Heaven Fighters above the fourth level are the real help of the Federation.

Looking at the source dragon group from the distance from the fortress is extremely shocking. It was an epic feeling, with tens of thousands of source dragons rushing in like a tidal wave. Quickly rushed towards the Dragon Source Star Base.

At this moment, the shield outside the base suddenly disappeared and was instantly retracted, and suddenly, a large number of source dragons crossed the range of the previous shield and rushed straight towards the base.

The shield opened again after ten seconds, separating the source dragons that rushed in front of them from the source dragons behind, and a strong and dense collision sound sounded, and a large number of source dragons were blocked out. And there are thousands of source dragons who have already rushed in.

In the distance, the huge source dragon that was a hundred meters away opened its mouth violently, and a huge pillar of light erupted from its mouth, blasting straight in the direction of the base shield.

On the fortress, a huge soul guide cannon with a diameter of more than five meters roared instantly, and it also blasted out a huge pillar of light, passing through the one-way defensive shield to meet the strong light.

The two rays of light collided in the air, bursting out with a flood of light that sent countless source dragons flying.

The tactics of the Douluo Federation military are not clever at all, that is, to isolate the beast tide through the fortress shield, and then kill those source dragons that have been put in in melee combat, and harvest the dragon source crystals.

But this is based on the strong defense of the base, and at the same time, it is also based on the premise that the source dragon is stupid enough......

The mecha divisions at the head of the city seemed to have received an order, and they jumped down from the city head one after another, meeting the thousands of source dragons who were released in.

Sure enough, as Yan Ruoting said, there was no long-range attack release, it was a heat-sensitive weapon that injured Long Yuanjing, and it was all melee combat.

There was no need for Yan Ruoting to say, Lan Xuanyu had already shouted in a deep voice: "Everyone release the fighting armor and enter the battle." The first group is in the front and the second group is in the back. The third group of support. The fourth group controls. ”

The unified silver fighting armor was released one after another, and the whole body was worn. Qian Lei was the first to jump down, he was the only one who didn't release the Dou Armor, because the gold Beamon's hair defense was already extremely strong. For him, Dou Armor will be somewhat restrictive. At least in the case of the one-word Dou Armor, his Dou Armor is not very useful. In this regard, Lan Xuanyu didn't know what to do, and always felt that Qian Lei's fighting armor might have to go through a special design.

The head of the fortress is also hundreds of meters high, but it is nothing for the soul master, Qian Lei slid down against the wall of the fortress, and the hair behind him produced enough friction, and even with a piece of spark, it quickly landed.

The others followed suit, landing quickly.

Yan Ruoting got back on the mecha and flew up, controlling her mecha to levitate in mid-air, paying attention to these teenagers from Shrek Academy.

Although she was a little dissatisfied with Lan Xuanyu and the others for inducing the source dragon beast tide, these were the pride of Shrek Academy after all, and she didn't dare to relax. Although the Heaven Fighter is at his own risk, the Heaven Fighting Department still needs to take responsibility to a certain extent, such as whether the difficulty of the task is in line with the level, and when it is possible to help the Sky Fighter, he must also help.

Therefore, she did not directly participate in the battle, but paid attention to these teenagers, and once she found that they were in danger, she would still help them in time.

In Yan Ruoting's heart, in fact, from the time Lan Xuanyu and them boarded the spaceship before, she was a little disappreciative in her heart. Because there are too many people. Dozens of people on a mission together, what does it mean? It means that the strength is insufficient, huddle together to keep warm! At least in her opinion.

At this time, under her gaze, the thirty-three teenagers had already descended from the city, and did not rush into the battle, but quickly formed a formation. The young man who had spoken to her earlier sat in the center, and then they collectively rushed in the direction of the source dragons.

The young man who jumped off the city first, his body quickly swelled, and in the blink of an eye, it had swelled to a height of four meters, what was that thing in his hand? Meteor hammer? Why did it look so familiar? It was so big!

Yan Ruoting was stunned, and these teenagers had already rushed to the front of the source dragon group.

A ball of fire rose into the sky, as if there was an extra sun out of thin air, and immediately after, a series of fireballs had already burst out, heading straight for the source dragon group and bombarding it.

Longyuan Star Base Headquarters.

A general with the rank of major general is watching the battle on the large screen in front of him. As the chief officer and commander-in-chief of the Longyuan Star Base, Lei Junze commanded the entire battle.

He suddenly saw a large number of fireballs appear on one of the big screens, and he couldn't help frowning, "That part of it? Who made them attack with the fire element? I don't know if it will destroy the Dragon Source Crystal?"

"It seems to be a sky fighter. A staff officer next to him said.

"Zoom in and see. Lei Junze said in a deep voice, his voice was already a little angry.

After many tests, the dragon source crystal has long been proven to be a very good energy source, which can be positively circulated with the monomer source core, and there is no need to refine it at all, the more powerful the source dragon, the higher the quality of the dragon source crystal produced. It is now considered by the Federation as an important base for long-term energy supply.

And just as Lan Xuanyu guessed, the best way for the base to obtain Dragon Source Crystal was when the beast tide was in place. A large number of source dragons were sent to the door. So, how do you take out all of their Dragon Source Crystals? Naturally, you can't bombard them with a powerful soul guide weapon, which will destroy the Dragon Source Crystals. That's why there is this melee combat method.
