Tang Yuge said in a deep voice: "The gold element here is extremely rich, and the concentration should exceed ninety percent. Although these Longyuan gold can only be regarded as low-grade rare metals, they are extremely large, and just mining and refining them is a great harvest.

"There are a lot of source dragons out there, and many of them are extremely powerful. They will be very sensitive to the gold element, but what I simulated with Jin Dun is the form of Dragon Source Gold, so they should treat us as Dragon Source Gold and not feel our existence. The magnetic field here can't detect what's going on underground, and it's understandable that it can't be detected, but I'll have to keep it up. ”

Lan Xuanyu said, "With your cultivation, how long can it last?"

Tang Yuge said: "No problem, I have the support of the soul core, and the gold element here is so abundant, enough for me to absorb and transform, without fighting, there is no problem in casting the golden escape for a long time, why do you continue to go deeper?"

"Let's go. With your golden escape, it seems that the possibility of us completing the task has increased greatly. Lan Xuanyu said with a smile. Being able to use the Golden Escape to infiltrate is their unique advantage, and it is an advantage that many Heaven Fighters do not have.

No matter how dangerous this gray area is, as long as Tang Yuge can cast the Golden Escape, even if it is on the ground, unless they encounter the Source Dragon head-on, they will not be discovered, and they will only be treated as the Dragon Source Gold. This is the strength of Tang Yuge.

A faint green light emanated from Lan Mengqin's body, enveloping the four of them, making everyone feel refreshed. It's pure vibration energy that keeps them in tip-top shape.

Tang Yuge led the three of them to go deeper, they didn't actually have a clear direction, but Tang Yuge was able to find the way he came with the memory of the gold element, so he didn't have to worry about getting lost in the gray area.

Tang Yuge led the three of them deep into the gray area, and at the same time, he felt everything outside with his perception of the gold element.

There are also many source dragons in the gray area, and judging from the breath, the eighth-level source dragon, which is very rare outside the gray area, is extremely common here. There were also some aura that was particularly powerful, and Tang Yuge didn't dare to use his spiritual power to mix the gold element to probe in the past.

"Xuanyu, something is wrong. Tang Yuge said in a low voice.

"What's wrong?" Lan Xuanyu hurriedly asked.

Tang Yuge said: "We have been advancing for almost half an hour, and in the place we just passed, I felt at least five suspected ninth-level source dragons. The ninth-level source dragon is at least equivalent to our Super Douluo-level powerhouse wearing Dou armor, or even stronger. There are also hundreds of eighth-level source dragons.

"And what we're looking at right now is at most one percent of the gray area. If calculated according to this density, the number of high-level source dragons in this gray area would be an extremely terrifying number. With such terrifying strength, why don't they attack the Dragon Source Star Base?"

Lan Xuanyu immediately understood what Tang Yuge meant, the source dragon obviously knew about the existence of human beings, otherwise he would not have often launched the source dragon tide to attack the dragon source star base. It is true that the base is well-equipped and there are many strong people, but if in this gray area, there are not just one or two, but hundreds, but hundreds, what kind of concept is that? If they attack with all their might, it will be enough to destroy the base. But why don't they attack, and let humans hunt them instead?

According to the situation recorded at the base, even if it is the source dragon tide, there is only one ninth-level source dragon at most at a time.

The base had never been able to probe the inside of the gray area in depth, which meant that the federal military did not know that there were so many ninth-level source dragons here.

Just by discovering this situation, Lan Xuanyu and the others were equivalent to completing most of the fifth-level team Doutian task.

"If we find out why this situation is happening, we should be able to complete the task. Lan Xuanyu's spirit was also a little dignified.

According to the judgment of the Federation, the source dragon is a creature without intelligence and fights only by instinct.

But when he first came to Longyuan Star, Lan Xuanyu felt a little strange, if the source dragon really didn't have any wisdom at all, then how did they judge the timing of advance and retreat? If their instinct was to fight, why had there never been a case of cannibalism between their kind? And the source dragon tide was not like a battle without a command at all.

In this gray area, they found so many powerful source dragons. Could it be that Yuanlong is wise, and what conspiracy can't be achieved?

The Dragon Source Crystal produced by Dragon Source Star is now very important to the federal government, it is pure energy, which can be directly used as the core energy source of warships, which greatly meets the needs of the Federation in terms of warship energy, so that the Federation can put more resources on building warships.

Lei Junze, who guards this resource star, is even about to be promoted from major general to lieutenant general, and through this incident, you can see how important the resources of the Dragon Source Star are to the Federation.

This resource star itself is still near several administrative stars of the Federation, so you don't have to worry about being attacked by foreign forces or interstellar pirates, everything is so perfect.

The more he thought about this, the more Lan Xuanyu felt that something was wrong, and vaguely, he felt that he had caught something, and he couldn't be completely sure.

"Let's continue to go deeper, you continue to probe, recording the number of ninth-level source dragons found. Lan Xuanyu said in a deep voice.

The four of them continued to go deeper, and the underground world seemed to have become their domain, and Jin Dun's ability was too suitable for them to hide themselves here.

Lan Xuanyu and the others even lifted their fighting armor to reduce Tang Yuge's burden as much as possible.

Continuing to move forward, often changing directions to probe, Tang Yuge's expression became more and more solemn.

She could feel that although the distribution of source dragons on the ground was not very even, the number of powerful source dragons was very large. She had already felt the aura of the ninth-level source dragon again and again. She had no doubt that if they appeared on the ground now, they would definitely be torn to pieces by the source dragon above. Because there are too many powerful source dragons above.

You must know that the source dragon has reached the ninth level, and with the ability to control the gold element, it is enough to carry out a large-scale terrorist attack such as a metal storm at any time. If there is only one Source Dragon, they can also try to fight it. If there were two source dragons, they would almost certainly die, not to mention, there were so many eighth-level source dragons.

"XVI. Every time Tang Yuge reported the number, Lan Xuanyu's expression became solemn. They had already discovered sixteen suspected ninth-level source dragons.

Fortunately, the tenth-level Source Dragon has not yet been discovered, it is a terrifying existence whose strength is at least equivalent to that of Extreme Douluo, and it may even be a god-level terrifying existence, otherwise, the other party may find them.

Suddenly, Tang Yuge stopped and turned his head to look to the right in surprise.

"What's wrong, Yuge?" Bai Xiuxiu asked.

Tang Yuge said: "Something is wrong over there, my spiritual power detected it and paused over there." There seems to be a cave over there. ”

"Huh? Lan Xuanyu said immediately.

He was actually ready to let Tang Yuge retreat with everyone, although they were only traveling underground, but this discovery was really amazing!

There are so many ninth-level source dragons in the gray area, even if a god-level powerhouse enters it, I am afraid it will be difficult to retreat with their whole body. What's more, it is not known if there is a tenth-level source dragon. There are so many powerful source dragons, but they don't attack the base, why is that?

This news alone is enough for the Federation to dispatch troops.

Tang Yuge moved to the right with the three of them, and suddenly, she stopped, turned her head to look at Lan Xuanyu, and her expression became extremely solemn.

Reading is exciting, reading is wonderful!
