"Commander Xiao Mu, you are all elites of the Human Federation. In the future, I don't want any of you to be damaged in battle. Protect yourself, do you understand?"

"Ship Yue, we understand your kindness. We will put our own safety first." Mu Feng also solemnly promised Yue Lin.

"Good luck to you!"

"Thank you, Mr. Yue!"

...

"Report to Mu Mu, the team has been assembled, and I request to set off!"

"Set out!" Mu Feng ordered loudly.

The barbarian natives were able to gather 100,000 troops on the periphery of Base No. 3 without knowing it, and there were so many flying beasts because they had an underground security secret passage.

This secret passage is one of the core secrets of the barbarian indigenous peoples. In fact, the human military also knows that there is a very large underground space underground on R Star.

However, the underground space is very responsible, and the human military itself is exploring. The underground space is not only mysterious, but also full of unknown dangers, but also mysterious treasures.

Of course, as long as it involves underground, mysterious treasures are always keywords.

There are indeed many magical places underground, which can be obtained from the memory of obtaining the "Star of Confusion". You can walk this secret passage and not get lost for thousands of kilometers. Among the barbarians, only the priests can do it!

Not all pastors can do it, but only a special pastor can do it.

Without the power of technology, we can only rely on the mysterious supernatural power. When Mu Feng and the others learned of the existence of secret sects, they naturally would not choose to swagger over the ground.

After all, when passing through the ground, the goal is too obvious and it takes a long time.

They have more advanced underground transportation tools and obtain memory maps of secret passages from the memory of "Misfortune" and can completely walk from the underground.

That only takes one day!

Save two-thirds of your time, why not do it?

The secret passage was under the barbarian indigenous camp. They had already dug a tunnel to come up from below. Although the barbarian indigenous people wanted to destroy it when they evacuated, they still failed to be completely successful in the end.

Therefore, Mu Feng and his team led the "Eagle" to dig a little and then entered the underground secret passage, which was four or five hundred meters above the ground.

It is also difficult for satellites from the Human Federation to discover creatures under the ground in depth. Even if they discover them, they still think it is the activity of the earth's biological groups.

There are indeed many barbarian groups of beasts living underground on R Star, and some are very powerful. Even the barbarian natives dare not easily become enemies with them.

Mu Feng and the others are very skilled and brave. Whether they walk on the ground or on the ground, there are dangers. Since the barbarians can come from this secret passage, what else can they be scared about?

Mu Feng has rich experience in underground adventure, hundreds of kilometers underground, and has lived for nearly two months. Even an adventurer like Ouqi may not be able to compare with him.

Moreover, he also has advanced instruments and equipment, as well as the assistance of the intelligent life of "Zhizi", which can predict dangers and avoid them in advance.

Therefore, unless there is a geological disaster underground, the danger is actually much smaller than that on the ground.

It is also unnecessary to walk with your legs underground. The underground hover truck is enough to pass through the tunnel. Even if it encounters a narrow passage, it can be directly penetrated.

This is the power of technology.

One thousand five hundred people, this is already a considerable force, not to mention that the minimum cultivation level of the members of this team is above the seventh stage of the acquired day.

With such a team, there are no few that can be found in the entire Human Federation.

There are all kinds of talents, covering almost all disciplines of mankind, and it is not uncommon for one person to have several disciplines.

"Mu pointed out that an underground lake was found in front of him. After the water was underwater, it was unknown luminous objects, suspected to be diamonds..."

"diamond?"

Although diamonds can be synthesized manually, they are basically no different from natural ones, but the cost is much lower. However, natural diamonds are still one of the precious gems!

"Continue to investigate and move forward, wait for me to come!" Mu Feng ordered.

"yes!"

A few minutes later, Mu Feng led the brigade to the underground lake that Mark Mond had just reported on the channel. The lake was very large, with thousands of square meters, and it should be a squeezed lake.

When the lamp tubes illuminate, there are indeed shiny things that refract from the bottom of the lake. What is it, it is not very clear.

A underwater robot was put on!

Soon, the underwater robot collected samples and shiny things from the bottom of the lake.

The lake water sample is measured and analyzed, and the samples of the bottom of the lake must also be collected, taken back, and various scientific experiments.

These are also counted as points.

"Mu Zhi, the water here is very clear and rich in negative ions. The crystals taken from underwater have been initially determined that they are not diamonds, but crystals, and it is also very difficult."

Although it is not a diamond, it is at least a very useful mineral, and this is not undetected.

"Go forward at full speed. If you don't find it special, leave a mark, pick the specimen, take it back for research!" Mu Feng didn't want to waste time. They were not here to conduct underground mineral investigations.

"yes!"

The speed of progress was accelerated. After five or six hours, I walked two or three hundred kilometers underground. This distance was still within the control of the human military.

keep going.

For about ten hours of continuous progress, Mu Feng ordered the team to stop and rest, and ordered the distribution of food and water.

Set out again.

"Mu's finger, the front channel is narrower, please slow down!" Mark Mond shouted in the communication channel.

"I know, everyone slows down!"

The hovering car suddenly entered a huge space through a narrow corridor. In the memory of "Muo Xing", it was a transfer station for them.

They left behind a large number of food, supplies and guards here.

Now the food and supplies here are still there, but the guards have long disappeared. It is obvious that the barbarian indigenous troops who fled back from the underground secret passage have all run away.

"Clean the passage and inform General Jin Hao, and ask him to send troops to occupy the place immediately and guard this throat to the area controlled by our humans."

"Yes, Mu Zhi!"

"Mu Zhi, I took people to check it out. There was no storage of much food and food here. Some of them were taken away by the fleeing barbarian indigenous soldiers. If I were them, I would definitely set up an ambush in this passage..." said Xin Shuilian, the leader of the intelligence team.

"It should be no longer the area where we humans are controlled. Next, we have to be careful. These barbarian indigenous people are not that simple." Mu Feng said, and he had a premonition that the next march would not be so smooth.

"yes!"

"Tyuko, draw a three-dimensional map of all the spaces and channels nearby here immediately!"

"I understand!" Released the micro-drone and quickly drilled into the passage. These drones were like omnipresent ants, quickly detecting the underground passage.

A very three-dimensional underground image appeared on Mu Feng's personal terminal and was shared with everyone in the team.

Suddenly Mu Feng felt a trace of mental fluctuation!

He raised his hand, aimed at a certain direction, and slapped him in the face!

“Ga…”

Only a scream was heard, and it quickly disappeared again.

"What's going on?" Fan Chenxi and others quickly surrounded Mu Feng and observed it in surprise. Obviously, they found nothing.

"Our whereabouts have been exposed, but he can't do it even if he wants to pass the news back, because he himself has also exposed it!" Mu Feng said.

"Invisible?" Qianye Jingshou said.

"That's right, in addition to invisibility, he also has a form. If he hadn't been discovered by me just now, it would have been difficult to find his existence!" Mu Feng said, "He was injured by me, and he didn't run far, and he didn't dare to run. Block the entrance and exit, and search carefully!"

"yes!"

This guy couldn't let the news be saved back. Mu Feng slowly closed his eyes, and the golden light of the soul in the sea of ​​consciousness suddenly radiated thousands of feet of light!

This guy who can invisible and imitate must be a priest from the barbarian indigenous people. Everyone else left, but he stayed, obviously expecting that the human federal military would discover the existence of this underground secret passage.

"Dawn, count up at your nine o'clock direction, the third stone, hurry!" Mu Feng sent a message on his personal terminal.

Fan Chenxi took a quick action and grabbed the stone in an instant!

He is under the stone!

Mu Feng only discovered the existence of the barbarian indigenous priest, but he did not expect that this guy was actually hiding under the stone. It was obviously a premeditation.

It's too late, then it's time to go.

Fan Chenxi is a master who is about to advance to the sixth stage of the innate level. Although the barbarian indigenous priest express delivery was dissatisfied, it was Fan Chenxi's opponent!

A flash of light, the barbarian native was injured again, and then a large net fell down and tied him up tightly.

"Of course he is a barbarian priest!" Mu Feng walked over and saw that it was undoubtedly a barbarian native, and shouted, "Guide Ouqi, come here."

"You have captured a barbarian indigenous priest?" Ouqi was surprised when he saw the barbarian indigenous priest who was tied up like rice dumplings.

"Just him, you know the native language of the barbarians here. Come and ask him, what is the situation in Heifengling now?" Mu Feng ordered.

"Mu Zhi, you are not kidding, I asked him, will he say it?" Ouqi said.

"You ask him, if he doesn't say it, we'll find another way." Mu Feng smiled.

"Okay, okay..."

Since Mu Feng knew what the situation was in the barbarian indigenous priests, he naturally thought of how to cure them. Unless he was really a ghost who would rather die than surrender, it would be easy to pry open the barbarian indigenous mouth.
