Buried three corpses.

No matter what happened before these three people, they would still be buried in peace after death, this is considered accumulating virtue.

Where did the underground river flow? This is not the purpose of Mu Feng and his group. They followed the roadmap provided by the adventurer "Sweeping the World" and finally arrived at the place where he came from the ground.

This is another bottomless black hole.

The color of the rock at the entrance of the cave was gray-brown, but after walking down a few hundred meters, the color of the stone began to change and the color became darker and darker.

Judging from Professor Zhuang's decades of geological research experience, this earth cave cannot be artificial, but can only be formed by the great power of nature.

The channel is curved, but the overall direction extends downward.

What’s very strange is that the air here can make people breathe freely, which also shows that this passage must be connected to the ground.

This also calmed everyone's uneasy heart. As long as they could be connected to the outside world, it means that there was a way out. If it really didn't work, they could still return the same way.

"What's the sound?"

"It's the sound of water flowing. It seems that we are now under the underground river." After listening carefully for a while, Professor Zhuang analyzed and judged.

"The water droplets condensed on these rocks, Professor Zhuang is right. We are now under the underground river, but this river is really unfathomable. We have walked at least seven or eight hundred meters down!" Mu Feng reached out and touched the rocks in the passage, his fingertips were very wet.

Keep moving forward or continue to go down.

Such a journey is very boring. Fortunately, there are more than one of them. It is hard to imagine that if they were one person, in such an underground world, he would have to overcome such a great psychological fear in order to keep moving forward.

"It's so boring, it's not fun at all. I'll sleep with beauty." After entering deeper underground, the yellow-haired parrot showed great interest. He looked east and west. As soon as the freshness ended, the little thing became weak and simply hid in Mufeng's arms and went to sleep.

Zhuang Hui despises this kind of "traitor" very much and always calls it "focus on sex over friends".

Mu Feng was also helpless. The bird liked to follow him when he was rushing. When it was time to rest, it went to find Zhuang Hui again.

Although the journey was boring, it was a rare scientific investigation for Professor Zhuang and his party. Whether it was the collected rock specimens or the recorded images and text materials, it left first-hand intuitive information for the study of the formation of foggy forests and the complex world underground.

"What, oh!" Fang Kexin, who was walking in the middle of the team, suddenly sprained her ankle and screamed.

"Be careful." He quickly put his eyes on her waist.

"Thank you, Team Eagle leader." Fang Kexin suddenly felt a masculine breath rushing into her nostrils, her whole body softened, and her cheeks turned red.

"Let me see what it is?" Mu Feng did not pay attention to the change in Fang Kexin's face, but bent down and picked up the stone that was smearing Fang Kexin just now.

"Student Fang, you are really the daughter of luck in our team." When Shi Tou was placed under the light, Mu Feng and everyone were shocked.

"Diamond, such a big diamond..."

Pure and transparent, full of light, extremely perfect.

Fang Kexin was stupid.

I was almost defeated by a huge naked diamond, and my luck was too amazing.

"I, I don't know..."

"Along the way, Student Fang's luck has always been the best among us. It seems that God favors us." Lan Xin said in surprise.

"Yes, such a large diamond is worth at least 500 million or 600 million. It should belong to..." Mu Feng was about to announce, but Fang Kexin suddenly objected loudly, "I didn't find this diamond, it was discovered by the Hawks leader. It should belong to the Hawks leader."

Strictly speaking, it was indeed the diamond discovered by Mu Feng, but if Fang Kexin had not had the sprained kick, Mu Feng might not have paid attention to his feet.

"Let's do this, this diamond belongs to you two who discovered it together, and you two are just divided equally." Professor Zhuang said with a smile.

"Professor Zhuang, if you say that, I think this diamond does not belong entirely to both of us, and everyone should have a share." Mu Feng said, "It's better to follow the old rules. The discoverer gets half of it, and everyone will share the rest equally. How about it?"

"This is not very good, we get nothing for every effort..."

"We are now a team. Didn't we come here without taking care of each other and helping each other?" Mu Feng said decisively, "I am the team leader, that's it."

"Student Fang, what do you think?"

"I listen to the leader of the Eagles." Fang Kexin is very smart. She should not enjoy unexpected wealth alone, as she will be jealous of others.

"The Eagle leader, if this trend continues, we all become billionaires after we go back." Yao Shijie smiled, "No wonder the Mist Forest attracts a large number of adventurers every year. No one can resist the temptation of getting rich at night."

"What a big diamond here? Maybe there is a large diamond deposit here. I just walked all the way and found the diamond primordial rock. You see, this dark blue rock is kimberlite, which is usually formed in the depths of 150 to 300 kilometers underground in the planetary body. Kimberlite is a kind of alkaline basic volcanic rock containing volatile components such as carbonic acid gas..."

"The volcanic activity in the Mist Forest is frequent, and diamonds underground often erupt with the volcanic magma. It is not surprising that there are rich diamond mines here. Someone once brought out a five-kilogram heavy red diamond rough stone from the Mist Forest, worth hundreds of billions of federal credit points..."

Most people are not very clear about the formation of diamonds, but for scientists engaged in geological research, this is similar to common sense.

"Professor Zhuang, diamonds have been formed for at least one billion years, and even legend has it that some ancient diamonds are almost the same age as the universe?"

"Haha, there is no accurate conclusion on how old the universe is, but the oldest diamonds in the world are over 4.5 billion years old. Our human mother planet Earth is almost at this age."

"So that's the case. Thank you Professor Zhuang. We have learned a lot along the way with you. It's really worth the trip."

"We learn from each other, and you have also taught us a lot of experience in survival in the wild."

The diamond rough stone obtained by Mu Feng and others is about three to four hundred carats, and the market estimate is at least 500 million or 600 million, which is also extremely rare.

Fang Kexin's good luck aroused everyone's enthusiasm for treasure hunting, and everyone began to pay attention to their feet.

Diamonds are not ordinary gems. The reason for their formation is too harsh and the time is too long. If it weren't for Fang Kexin's unscrupulous luck, they might have missed it.

Maybe they won a first prize at the beginning, but then God took away his luck. They went along the way and did not find a second diamond.

Although I couldn't find it, everyone's enthusiasm did not decrease.

With such a primitive motivation, at least the leader Mufeng, as the leader, doesn't have to worry about everyone's morale along the way.

Walking with weight for a long time is very harmful to your feet.

Even professional soldiers who have received special training have had blood blisters grinding out of their feet, not to mention scientific workers like Fang Kexin and Tang Huojun who are delicate in the laboratory.

"Hold on, I'll pick out blood blisters for you, apply medicine, and just take a nap."

Although there are no professional medical staff in the team, simple bandaging and medication are not particularly difficult for professional soldiers.

The ones I carry with me are special medicines developed by the military, which have very good results. I basically rest for one night and can walk the next day.

No one is sick, this is a very miracle.

The more you go down the ground, the lower the temperature, the lower the temperature, minus 70 degrees Celsius suddenly reaches minus 30 degrees Celsius. Everyone put on all the clothes that kept warm, but they still felt that it was OK.

And the temperature is still falling.

"Eagle, this won't work. We have to freeze to death before we find the Yuanjing Mine."

"What should we do? We have used all the means to keep warm. The spare fuel cannot be moved. Now we use it. Even if we find the Yuanjing Mine, we can't do any exploration?" Mu Fengdao.

"Do you still remember the pack of things we got at the python hole?"

"You mean those Yuanjings?"

"Yes, our energy supply for exploration equipment is actually made of Yuanjing, including our fighter mechas." Lan Xin explained.

"But those are the raw stones of Yuanjing ore. Can we use them in our current conditions?"

"Don't forget, we have the top scientists in the human federal government. Can't they do what you can't do?"

Yes, isn’t this guarding the nurse and looking for milk to drink?

When Professor Zhuang heard that there was a Yuanjing ore raw stone, he became excited.

This is a big deal. Before they saw the underground Yuanjing ore again, they could not tell whether these Yuanjing ores were brought out from this underground, so the two discussed and temporarily concealed them.

Now, when encountering practical difficulties, these Yuanjing ores have become their only life-saving straw to survive the current difficulties.

"Okay, with these Yuanjing ores, we can use the protection and warmth function on our personal mechas. According to my calculations, it won't take long before we pass through this frozen soil layer, and the temperature will rise."

The Yuanjing energy rod carried on the personal mecha is used to maintain combat consumption. Once consumed, the personal mecha will even become a burden.

So unless it is absolutely necessary, the individual combat mecha is the last line of defense and cannot be used easily.
