On the picture, Lan Xuanyu saw a sturdy triangular source dragon, and the horn on his head kept ejecting golden lights. These golden lights would magnify in the air and then turn into physical metal to launch an attack. It was a bit like the attack of the flying source dragon when their spacecraft landed.

This metal javelin not only has strong penetration, but also has great power. It will explode when attacked and burst out with a strong metal storm.

Those mechas cooperated very well and covered each other, so they used long-range attack firepower to cover the source dragons and consumed the source dragons. Obviously, they were also tentative battles.

From this point of view, Lan Xuanyu could tell that these people should have come to Longyuanxing for the first time, and they are not earlier than them.

This means that in this battle, they must test Yuanlong's strength. With their tests, Lan Xuanyu and the others can collect a lot of information by observing from the side without even taking risks on their own. Why not do it?

He led his friends to a hillside ahead. Lan Xuanyu ordered a temporary rest and then communicated with Liu Feng again.

"When you lure the Yuanlong, are there any danger?" Lan Xuanyu asked.

Liu Feng said: "Fortunately, these source dragons are not fast. Just as the data shows, they have low intelligence. Although their attack power is very strong, they do not have many means. Moreover, I don't need to attack them. As long as they appear within their field of vision, they will immediately charge at me and try to attack me. When I lead them to the vicinity of those mecha masters, it discovered a larger target and abandoned me. Well, a source dragon has been killed. They have indeed had a strong reaction to heat energy. The effective killing effect of soul-guided rays is OK. But it also takes multiple attacks to break through their body stratum corneum defense."

"The second head is dead. There is still the last one left, the one I guided the past. Overall, these source dragons are about the same as the combat power of a hundred-year soul beast of ordinary attack type, and are not very strong. One of them has a larger body and can barely have the combat power of a thousand-year soul beast. But during the battle, they can obviously activate the metal elements on the Dragon Source Star to assist themselves, and their attack power will be greatly enhanced."

Lan Xuanyu said: "Okay, I understand. Continue to track those mechas, give us direction marks, and we will follow."

Ten minutes later, Lan Xuanyu and his classmates saw the huge corpse of the Santou Yuanlong.

The two of the source dragons are about four meters long, and one is more than six meters long. It should be the larger one Liu Feng said.

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

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

Tang Yuge squatted beside Yuanlong, pressing one hand on Yuanlong's body, and a faint metallic luster suddenly bloomed around her body, connecting with Yuanlong's body through her palms.

After a while, Tang Yuge narrowed his eyes slightly, frowned slightly, and said, "Somewhat strange."

Lan Xuanyu asked, "What's strange?"

Tang Yuge pointed to the big hole dug in the head of the source dragon and said, "The dragon source crystal should be on the head. It is their energy core. However, if the dragon source crystal is lost, the whole body has been metalized after the source dragon dies. So, you can regard the current source dragon as the carved metal. This is not a dead life form at all, but a large piece of dragon source gold."

"Hmm?" Lan Xuanyu's heart moved.

"In other words, these corpses of the source dragon become dragon source gold? Can I understand this way?"

Tang Yuge nodded and said, "Yes. But there are many impurities in it, and it needs to be refined through refining to be a real rare metal. Impurities account for about 40%. Sixty percent of ordinary dragon source gold can be extracted. Then through forging, the effect will be better. These dragon source golds are very pure gold elements and have a strong affinity for gold elements. They are considered good rare metals."

As she spoke, her palm turned fiery red, and suddenly, the surface of the Yuanlong corpse began to melt.

"But this Longyuanjin seems to be afraid of heat energy. This thing cannot be used as a mecha, right? No wonder the information given by the Doutian Ministry only says that they are suitable for making monomer positive circulation source cores." Tang Yuge said.

Lan Xuanyu nodded slightly, and then he touched the body of the three-headed source dragon into his ring of fate. This is a rare metal. Although there are many impurities, it is not small in size! These three-headed source dragons are several tons. It is enough to refine hundreds of kilograms of rare metal.

For some reason, 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 move? These source dragons will turn into metals if they lose the dragon source crystal, or even food for other source dragons. Then how did their instincts come from?

Even if wisdom is underground, they should be wise! Low-level wisdom is also wisdom. After all, they are all living creatures.

Although he was thinking this way, the facts were right in front of him, and he didn't know what was going on. He couldn't judge.

The Federation should have discovered this situation, but the Federation did not respond. It must have been studied in detail.

After getting the Dragon Source Crystal, let’s see what’s going on.

Hiding his doubts in his heart, Lan Xuanyu and his friends set out again, still following the route guided by Liu Feng, chasing the mecha in front. He sent agile attack soul masters on both sides to be responsible for reconnaissance.

The combat power of those mechas is really quite good. In two hours, they have picked up more than a dozen corpses of source dragons. Among them, the highest level is level 4 source dragon.

It is not that the mecha masters do not want to take these corpses away, but that compared with the corpses of the Source Dragon, the dragon crystal is obviously more valuable and does not occupy space. Not everyone has a huge storage soul guide like Lan Xuanyu.

The price of a storage soul guide that can store mechas is almost astronomical. Five purple-level badges are required at Shrek Academy to redeem.

After storing the mecha, where can there be a place to put the corpse? But Lan Xuanyu can! His ring of fate has a total of 10,000 cubic meters of space, and he used to be equipped with a warship.

So, after picking up more than a dozen corpses, this is a real gain. The federal military probably is not very interested in this thing. Their current task is to obtain dragon crystals. But after taking them back, they can be refined into rare metals. Even if they cannot make battle armor and mechas, they can still be sold to the academy! These are all badges, and they can be collected without any effort.

Through the battle scenes that Liu Feng kept passing back and the careful observation of Yuanlong's corpse, Lan Xuanyu and the others gradually became familiar with Yuanlong.

Another hour later, after picking up the six-headed dragon corpse, the sound from Liu Feng suddenly became excited in front of him.

"A big one came, at least equivalent to a ten thousand-year-old soul beast. It is probably a source dragon above level six." As he said, he passed the picture back.
