When Roland said the four words of the bronze gate, Lu Yuan and others couldn't help but take a breath.

And they could also feel Roland's fear.

Yes, it is not incredible and fearful to find such traces of human activities in a cave that may not have been stepped into for tens of thousands of years.

"What then?" Lu Yuan asked.

"Then we tried to open the bronze door," Roland said.

"Actually, the results of the test at that time were very suitable for human survival."

"The underground depth is about minus 500 meters above sea level, and the temperature is between 40 and 50 degrees Celsius all year round. If heat is used with suitable thermodynamic pipelines, heat can be used to heat it easily, and it can easily support a large community of more than 2,000 people. There are also a variety of fungi and rodents here, and the food supply is also guaranteed, and it has the potential to develop agriculture. In terms of water source and air, the gas content of sulfur dioxide in the air quality is slightly higher, but it is not a problem that technology cannot solve. As for water quality, it is mainly due to inorganic salt exceeding the standard, which is equivalent to salt water in another sense. However, as long as there is water supply, it is not a big problem."

Looking back to this day, Roland's reaction is still talking about the benefits of this underground cave. It can be imagined that the members of the entire expedition investigation team were exploring this place that might represent their new hope at that time.

"But why, in the end, you are the only one left here?" Su Mei asked, "Where are the others?"

Roland stared at Su Mei blankly, with a dull expression, "Other people?"

He asked back, and then suddenly laughed in a daze, "Of course, everyone else is dead."

He just smiled foolishly, his calm expression before was completely gone.

Lu Yuan asked a few more questions, but the other party still smiled foolishly and refused to answer.

Lu Yuan looked at Su Mei, who bit her lip gently, observed Roland's expression, and finally said softly, "Maybe it was an emergency stimulus."

"Then today's inquiry ends here." Lu Yuan pressed his chest and bowed to Roland. "This is still your place to stay. We will leave you with enough food and water to ensure your safety and heal your wounds."

After saying that, Lu Yuan took Su Mei and John Smith to leave here.

...

...

"What do you think?" After locking Roland in his ward again, the trio gathered in the living room again.

The things in front of me became more and more strange. At first, I just wanted to save the alive victim, but who could have thought that such a long strange event would be brought out in a short time?

These things are hard to explain in science.

Especially in the underground cave at a depth of 500 meters, there is a bronze door inside.

Who would believe this kind of thing?

But for some reason, Lu Yuansumei and John Smith all believed what he said.

"When we went to the bottom of the cave, did we see the so-called bronze door?" John Smith asked, "I didn't pay attention anyway."

"The focus at that time was on rescuing Roland. It should be said that it was normal to not see it." Su Mei said, "But I really didn't notice it."

"If you want to know the taste of pears, you can only check it out yourself." Lu Yuan said, "We have been to the cave. Since this is the case, it is necessary to confirm the bronze door that Roland mentioned before."

"And also study the material of the bronze door, or other things worth paying attention to."

"Especially, what's at the end behind the bronze door?"

"Why did Roland's expedition end up being the only one left, and his refuge faced such a good natural shelter location, no longer have any ambitions."

"It's all weird and worth thinking about."

"Of course, including Roland's claimed companion, how did he die."

If it were before, if Roland said this, Lu Yuan and the others would really not believe it.

But Roland has taken the initiative to help Lu Yuan and others to confirm that the entrance of the cave is that no matter how it is blocked, it will see the light of day again. So now it is not completely unacceptable to say that there is a unique bronze door at the bottom of the cave.

After all, Lu Yuan and the others had just witnessed a hole that could repair and clear itself and could only take effect in an unobserved state.

Just by touching the conscience, I have to say that all this completely overturned the scientific cognition of Lu Yuan and others.

Simply put, the three views have been seriously damaged.

It’s nothing great if you think about it carefully, right?

"So who will go this time?" John Smith asked. "For now, I don't recommend everyone to go together."

When I went to rescue Roland, I had basically confirmed that the danger would not be fought, and everyone was wearing a doomsday mecha with iron-packed meat, so I could be fearless.

But now that Roland has already obtained the fact that the entire expedition team, except for him, is very unwise to dispatch the entire army on the far side.

Even if you take a step back, there is still a Roland locked in the ground-effect aircraft, and someone must guard it. After all, you know people but not your heart. What does Roland mean? What did he experience in the first place? No one dares to make a rash judgment on it without knowing all this.

After all, not everyone can make their own professional explanations.

How can the flying dragon lose in the face?

"I'm." Lu Yuan said it calmly without hesitation.

"I think I'm more suitable?" John Smith said quietly.

John Smith is the strongest, most combat-ready person in the trio. After all, the identity of a special military soldier is not in vain. Every day before his military career represented a lot of cruel training.

"No, you are more suitable for detaining and surveilling Roland here, and you can even chat with him." Su Mei said, "After all, if it were me, I would definitely not be able to beat him."

Su Mei is now thin and only about 1.6 meters tall, and weighs about 40 kilograms, which is really unbeatable.

The girl was recovering from a serious illness and was really weak and tight.

John Smith thought about it and could only nod, "So this time it's your father and daughter working together?"

Su Mei smiled, "After all, I never want to be separated from him again."

The girl smiled lightly.

"What do you think?" Su Mei looked at Lu Yuan. "Let's go together? OK?"

Under Su Mei's bright and clear eyes, basically no one could reject her proposal, and Lu Yuan was of course included.

He nipped his lip gently, "There is unknown in front of us."

This is not something in the field of science.

"It's because it's unknown." Su Mei smiled.

"So we should be together."

“Isn’t it?”

The girl's eyes were firm.
