Tang Yuge said in a deep voice: "The gold elements here are extremely rich, and the concentration should exceed 90%. Although these dragon source gold can only be considered low-grade rare metals, the number is too large. Just developing and refining them is a great harvest. There are many source dragons outside, and there are many powerful auras. They will have a very sharp sense of the metal elements, but I use the gold escape to simulate the shape of the dragon source gold, so they should regard us as part of the dragon source gold so that they cannot feel our existence. Even if the magnetic field can be explored below the ground, it is reasonable to not detect us. But the gold escape must be maintained."

Lan Xuanyu said: "How long can you last with your cultivation?"

Tang Yuge said: "No problem. I have soul core support, and the golden elements here are so abundant. They are enough for me to absorb and transform. Without fighting, there is no problem in maintaining it for a long time. Should we continue to look inward?"

"Let's go. With your Golden Escape Method, it seems that the possibility of our mission has been greatly enhanced." Lan Xuanyu said with a smile.

The unique advantage of the Golden Escape is that other teams of Doutian Douzhe do not have. No matter how dangerous this gray fog area is, even if it is covered by the Golden Escape, even on the ground, they will not be discovered unless they encounter the Origin Dragon head-on, and will only be regarded as part of the Dragon Origin Gold. This is the power of Tang Yuge.

A faint green halo was released from Lan Mengqin and enveloped the four people, making everyone feel energetic. This is a pure supplement to life energy and keeping it in state.

The dragon source gold ahead was broken again, and Tang Yuge led the three of them to continue inward. They actually did not have a clear sense of direction, but Tang Yuge was able to find the way to come with his memory of the gold element, so there was no need to worry about being lost in the gray fog area.

Tang Yuge led the three of them into the depths of the gray fog, while relying on the perception of the golden element, he felt everything outside.

The source dragons in the gray fog have a very high density, and many source dragons are very powerful. Judging from the breath, the rare level 8 source dragons outside are actually common here, and some auras are particularly deep and powerful. Tang Yuge dared not use his mental power to mix gold elements to explore the past.

"Xuan Yu, something is wrong!" Tang Yuge whispered.

"Why is it wrong?" Lan Xuanyu asked hurriedly.

Tang Yuge said: "We have been investigating for only half an hour. In the place we just passed by, I felt at least five suspected to be the level of the ninth-level source dragon. The level of the ninth-level source dragon is at least equivalent to the super Douluo-level strongman in our battle armor, and even stronger. The level of the eighth-level source dragon is enough. The range we are currently exploring is at most one percent of the gray fog. According to this density, in the gray fog, the level and number of the source dragons will be an extremely terrifying number. With such terrifying strength, why don't they attack the base?"

Lan Xuanyu immediately understood what Tang Yuge meant. The Yuanlong obviously knew that humans existed, otherwise he would not have launched the Yuanlong tide to attack the Longyuan Star Base. The base was well-equipped, and there were many strong people. But if the ninth-level source dragons in this gray fog area were not one or two, but dozens, what was that concept? If they tried their best, it would be enough to destroy the Longyuan Star Base. But why didn't they attack? Instead, let humans hunt the Yuanlong?

According to the records on the base, even if it is the Source Dragon Tide, at most a level nine source dragon appears each time.

On the other side of the base, I have never found the situation inside the gray fog in depth. In other words, the federal military did not know that there were so many level nine source dragons in the gray fog. This reconnaissance situation alone was equivalent to a large part of the level five-level fighter mission of Lan Xuanyu and others.

"If we want to find this reason, it should be considered as completing the task." Lan Xuanyu's face was also a little solemn.

According to the judgment of the Federation, Yuanlong is a creature without wisdom, and is fighting by instinct. But when he first came, Lan Xuanyu was a little surprised. If Yuanlong really had no wisdom at all, how could they judge their advance and retreat? If their instinct is fighting and destruction, there has never been a situation of mutual corruption among the same species. There is also Yuanlong Tide, which is not like a battle without command.

In this gray fog, there are so many powerful source dragons. Could it be that the source dragon is wise? And is there any conspiracy still going on?

The Longyuan Crystal produced by Longyuan Star is now very important to the federal government. Pure energy can be directly used in the core energy of warships, greatly saving the Federation's demand for warship energy. It allows the Federation to have the ability to place more resources on warship manufacturing.

Lei Junze, who guards this resource star, is even about to be promoted from major general to lieutenant general. You can see how important the resources of Longyuan Star are to the Federation. This resource star itself is still near several administrative stars of the Federation. There is no need to worry about being attacked by foreign power or interstellar pirates. Everything is so perfect.

The more he thought about this, the more he felt that something was wrong. He vaguely felt that he had caught something, but he could not be completely sure.

"Let's continue to go deeper, you continue to explore and record the number of level nine source dragons found." Lan Xuanyu said in a deep voice.

The four of them continued to go deeper. The underground world seemed to have become their realm. The Golden Escape's ability was so suitable to hide themselves here. Lan Xuanyu and the others even removed the battle armor, reducing the burden on Tang Yuge as much as possible.

Continue to move forward and often change directions to explore. Tang Yuge's face became more and more serious.

She could feel that although the distribution of the source dragon on the ground was not very uniform, the number of the source dragon powerhouse 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. There were too many source dragon powerhouses.

You should know that at the level of the ninth-level source dragon, the control of the gold element is enough to launch terrifying attacks such as metal storm at any time and a large range. There is only one end, and they can try it. If there are two ends, they will almost die, not to mention that there are so many level eight-level source dragons.

"Sixteen." Every time Tang Yuge reported numbers, Lan Xuanyu's face became more serious. He had already discovered that the sixteen were suspected to be the ninth-level source dragon.

Fortunately, the level ten source dragon has not been discovered, which is at least equivalent to the extreme Douluo of humans, and may even be a terrifying powerful man at the god level. Otherwise, the other party might have the possibility of discovering them.

Suddenly, Tang Yuge, who was moving forward, stopped, and she turned her head to the right in surprise.

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

Tang Yuge said: "There is something wrong there. When my mental power was discovered there, it seemed to be empty. There seemed to be a hole there."

"Hmm? Come and take a look." Lan Xuanyu said immediately.

He was actually ready to let Tang Yuge lead everyone to retreat. Although they were just marching under the ground, this discovery was really amazing!

There are so many level nine source dragons in the gray fog range, and even if a god-level powerful man enters it, it will be difficult for him to escape unscathed. What's more, there are so many level ten source dragons. So many powerful source dragons do not attack the human base. Why is this?

This news alone is enough to allow the federal government to deploy troops.
