On the screen, Lan Xuanyu saw that a sturdy triangular source dragon with a single horn on its head constantly spewed out golden lights, which would be amplified in the air, and then turn into solid metal to attack. Kind of like the attack of the flying source dragon when their ship landed.

This metal javelin is not only very penetrating, but also very powerful, and when attacked, it will explode, bursting into a powerful metal storm.

Those mecha cooperate very tacitly, cover each other, and use long-range attack firepower to cover those source dragons, and consume the source dragons. Apparently also engaged in a tentative battle.

From this point, Lan Xuanyu could judge that these people should also be the first time to come to Longyuan Star, no earlier than them.

This means that in the midst of this battle. They will also inevitably test the strength of the source dragon. And with their temptation, Lan Xuanyu and they can collect a lot of information as long as they observe from the sidelines, and they don't even have to take risks themselves, so why not?

Take your buddies up a hill ahead. Lan Xuanyu ordered to rest in place for a while, and then communicated with Liu Feng again.

"Is there any danger when you lure the source dragon?" Lan Xuanyu asked.

Liu Feng said: "It's okay." These source dragons are not very fast, and as the information shows, their intelligence is low. Although the attack power is very strong, there are not many means. Moreover, I don't even need to attack them, as soon as they are in their field of vision, they will immediately charge at me and try to attack me, as soon as they are in their field of vision. When I lured them to the vicinity of those mechs. It found a bigger purpose and abandoned me. Well, a source dragon has already been killed. They are indeed very responsive to heat. The effective killing effect of the soul guide ray is okay. But it also takes multiple attacks to break through their body's cuticle defenses. ”

"The second head also died. There was only one last one left, the one I guided past. On the whole, these source dragons are about equivalent to the combat power of ordinary assault type hundred-year soul beasts, which is not strong. There is a large one, barely having the combat power of a thousand-year soul beast. However, in the process of fighting, they can obviously attract the metal elements on the Dragon Source Star to assist them, and their attack power will be greatly enhanced. ”

Lan Xuanyu said: "Okay, I understand." Keep tracking down those mechs, give us bearings, and we'll follow. ”

Ten minutes later. Lan Xuanyu and his classmates saw the huge corpse of the three-headed source dragon.

Two of them were about four meters long, and one was more than six meters long. It should be the bigger one that Liu Feng said.

"The four-meter-long one is about a second-level source dragon, and the six-meter-long one is about a third-level source dragon. Lan Xuanyu quickly made a judgment based on the information he had obtained earlier.

"Yuge, you come and check the corpses of these source dragons. Lan Xuanyu called Tang Yuge to his side.

Tang Yuge squatted down beside Yuan Long, one hand pressed on Yuan Long's body, and a faint metallic luster suddenly bloomed around her body, connecting with the Yuan Dragon's body through the palm of his hand.

After a while, Tang Yuge's eyes narrowed slightly, frowned slightly, and said, "It's a little strange." ”

Lan Xuanyu asked, "What's strange?" ”

Tang Yuge pointed to the big hole that had been dug in the head of the source dragon, and said, "The dragon source crystal should be in the head." It's their energy core. However, after losing the Dragon Source Crystal, after the death of this Source Dragon, the whole body has been metallized. So. You can think of the current source dragon as a carved metal. This was not a dead lifeform at all, but a large piece of Dragon Source Gold. ”

"Huh?" Lan Xuanyu's heart moved.

"In other words, the corpses of these source dragons have become dragon source gold?

Tang Yuge nodded and said, "Yes." However, there are many impurities in itself, which need to be purified by refining in order to be a real rare metal. Impurities account for about 40 percent. Sixty percent of ordinary Dragon Source Gold can be refined. Then through forging, the effect will be better. These dragon source gold is a very pure gold element, and it also has a strong affinity for the gold element. It's a good rare metal. ”

As she spoke, her palms turned fiery red, and suddenly, the surface of the source dragon's corpse began to show some signs of melting.

"But this Longyuan Jin seems to be very afraid of heat. This thing can't be used as a mecha, right? No wonder the information given by the Doutian Department only says that they are suitable for making a single positive circulation source core. Tang Yuge said.

Lan Xuanyu bowed slightly, and then he touched the corpse of the three-headed source dragon into his destiny ring. This is a rare metal, although there are many impurities, but the volume is not small! These three source dragons are several tons. It's okay to refine a few hundred kilograms of rare metals.

I don't know why, after listening to Tang Yuge's story, Lan Xuanyu also felt a little strange. If the Dragon Source Crystal is just a simple energy core, how can it provide these Source Dragons with the ability to act? These Source Dragons will turn into metal and even food for other Source Dragons when they lose the Dragon Source Crystal. So where do their instincts come from?

Even if they are underground, they should be wise! The lower wisdom is also wisdom. After all, they are all living creatures.

Although he thought so in his heart, but the facts were in front of him, and he didn't know what was going on. There's no way to tell.

The Federation should have found out about this situation, but the Federation did not react. It must have been studied in detail.

After you get the Dragon Source Crystal, let's see what's going on.

Hiding his doubts in his heart, Lan Xuanyu set off again with his partners, still following the route guided by Liu Feng, chasing the mecha in front of him. On both sides, a keen attack system of war soul divisions was sent to be responsible for reconnaissance.

The combat effectiveness of those mechs is really not weak. In two hours, they had already picked up more than a dozen corpses of the source dragon. Among them, the highest level has a fourth-level source dragon.

It's not that those mecha masters don't want to take these corpses away, but compared to the corpse of the source dragon, it is obvious that the dragon crystal is more valuable and does not take up space. But not everyone has a huge storage soul guide like Lan Xuanyu.

The price of a storage soul guide that can store mecha is already almost astronomical. At Shrek Academy, you all need five purple badges to redeem.

The mecha is stored, where is there a place to put the corpse! But Lan Xuanyu can! His Circle of Destiny has a space of 10,000 cubic meters, and he used to install a battleship in the first place.

So, more than a dozen corpses were picked up, which is a real gain. The federal military probably wasn't too interested in this thing. Their current mission is to obtain the Dragon Crystal. But after taking it back, it can be refined into rare metals, and even if you can't make bucket armor and mecha, you can sell it to the academy!

Through Liu Feng's continuous transmission of battle pictures and careful observation of Yuanlong's corpse, Lan Xuanyu and the others gradually became familiar with Yuanlong.

After another hour, after picking up the corpses of the six source dragons, in front of him, the voice from Liu Feng suddenly became excited.

"There is a big one, at least equivalent to a 10,000-year soul beast. It is estimated that it is a source dragon above level six. As he spoke, he sent the picture back.

It was a behemoth with a height of more than fifteen meters, its whole body was covered with dark golden scales, and its head was particularly large, a bit like the Tyrannosaurus rex in the earth dragon soul beast. But a pair of forelimbs are particularly thick, and they shine with its large head. There is a large tail on the back, and at the tip of the tail is a huge metal ball with a diameter of more than two meters. When it shook the metal ball, its tail would actually become longer, and the moment it swept out, the wind brought up a bit of a terrifying sense of destruction that destroyed everything.
