Although he didn't see it with his own eyes, he could be sure that what Tang Hao said must be the truth, if it was a simple accident, it would be impossible for him to die so strangely.

"Li Fei, I think we need to study it carefully. Be sure to find the murderer and figure out the ins and outs of the matter. Otherwise, sooner or later, something will go wrong with this tunnel. ”

"Yes."

"Alright, let's move on, maybe we'll find some clues."

Tang Hao said, taking the lead and walking towards the inside of the tunnel.

Li Fei and the others followed and followed Tang Hao into the tunnel.

After walking for a few minutes, the tunnel within the tunnel became much wider, and there was no longer the oppressive and terrifying smell just now.

However, the tunnel is still not easy to walk.

Tang Hao and Li Fei walked cautiously.

"How did you say those people were killed?"

"Who knows, perhaps, they were burned to death by volcanic magma."

"Maybe it's a volcanic explosion."

"Well, it's quite possible."

"Whether it was a volcanic explosion or not, in short, the unknown factors in this tunnel are a threat to us, and we must find a way to eradicate it immediately."

Tang Hao said as he walked.

Li Fei and the others also nodded again and again.

In this way, Li Fei and the others continued to walk forward.

After walking for another ten minutes or so, Tang Hao suddenly stopped and looked ahead.

"Hey, look, how many graves are there in front of you?"

Li Fei also noticed it and immediately asked.

"Yes, I saw that too. However, it does not seem to be a tomb, but a mineral crystallization that resembles a mound. I think we have to be careful and don't run around. ”

"Hmm."

Everyone nodded and looked ahead together.

When they saw the graves in front of them, they were also shocked.

It was indeed a crystal-like crystalline mineral.

"Yes, I finally believe that Tang Yuchen's speculation is correct, I think there must be a lot of such veins in the mine cave he said, and there are very many of them."

"There's one thing I can't figure out right now, what is the use of these things for us?"

"You may be wrong, if it were me, I would choose to use this mineral, because they are very rich in mineral resources, and they can also make a lot of weapons."

"Well, yes, if we dig them up, maybe we can make a lot of weapons, even nuclear."

"This team of my dragon country is extremely important to restore its national strength."

"Li Fei, I have something to discuss with you." Tang Hao said.

"Oh, what's the matter? Say it. Li Fei said.

"That's right, I have a plan, report to the top management, and build an underground factory here."

"Underground factory?" Li Fei asked curiously.

"A large underground arsenal, of course." Tang Hao said: "I plan to build a super giant large-scale production base. The mineral deposits here are just the right thing to use. ”

"And I'm going to build the arsenal near the magma crater."

"Near the volcano? Are you going to use volcanic ejections, or volcanic eruptions, to build this underground factory? ”

"That's right."

"That's too dangerous, if there is an earthquake underground, and the earth's crust is running, won't this underground factory collapse?"

"Well, this plan of mine is also a risk, but I believe that with the current level of technology in the Dragon Kingdom, this kind of thing is not impossible."

Tang Hao said with a smile.

"Hmm." Li Fei nodded.

"Okay, you make a plan, I'll make a report."

Li Fei nodded, and immediately took out his mobile phone to check it.

After about twenty seconds, Li Fei put down his phone.

"The report has been typed, and the top management also agrees."

"And I asked people to check the situation of the nearby volcano, it should be an active volcano, and the last eruption was 3,000 years ago."

"Really? Let me see. ”

Tang Hao immediately leaned over to take a look.

"Well, this is what happened when the volcano erupted, and it looks like the eruption should have been around three thousand years."

Li Fei looked at Tang Hao's mobile phone screen and explained carefully.

"Three thousand years, when the volcanic eruption must have been violent, maybe there were earthquakes and volcanic mud flows, are you sure to deal with these situations?"

"Well, we've got protection, and none of these things are a problem for us."

"That's good, all we have to do now is speed up, find the end of this tunnel as soon as possible, and get out of here."

Tang Hao said, moving on.

"Yes, Captain Tang." Li Fei and the others also followed Tang Hao and walked forward quickly.

In this way, Tang Hao and the others walked a few kilometers further, and suddenly, they saw a huge open space, which was the end of the mountain, and this was also the entrance to a tunnel.

"Well, this is the end of that mountain, it looks like there's something special about it!" Li Fei looked at the surrounding scenery and couldn't help but say.

"yes, not only is there something special about this place, but it's also the entrance to this tunnel."

After Li Fei heard this, he couldn't help but look around and said, "No wonder there are many volcanic stones on both sides of the tunnel, it turns out that the end of the tunnel is the entrance of the tunnel." ”

When Tang Hao heard this, he couldn't help but laugh and said, "That's right. ”

"Tang Hao, what kind of underground factory are you planning to build here?"

Li Fei looked at Tang Hao and asked.

"Of course, it's a huge underground factory, and my plan is to build a huge factory at the end of this tunnel."

Tang Hao said with a smile.

"Huge factory?"

Hearing this, Li Fei couldn't help but be stunned, he looked at Tang Hao in disbelief: "Is this huge factory that big?" ”

"Yes, it's five or six times bigger than the city we live in now, maybe even seven or eight times bigger." Tang Hao said and walked into the end of the tunnel.

After the report is typed.

The top brass takes this matter very seriously.

A day later, an orgyman regiment was sent to the mouth of the tunnel and a huge arsenal was built according to Tang Hao's design.

It's just that time is tight, but the scale of the factory is very simple, only three floors, and the outer wall of the factory is very thick, and the inside is also very empty, without any shelter.

"This factory has a rough appearance, it's not a giant factory at all." Li Fei couldn't help frowning.

"Hehe, this is a very normal thing, although the area we are in now is very vast, but in other places, it is also very desolate, so we have to build factories like this in other places."

"So what are we going to do next?" Li Fei asked.

"We can convert this place into a volcano factory, and then make the arsenal ready to use, and then we can build a bigger volcano arsenal." Tang Hao said with a smile.

"Oh, that's a good idea." Li Fei said happily.

"Hmm."

Tang Hao nodded with a smile, then looked at the huge flat ground, and said with a smile: "This stone tablet should be the place where the volcanic magma flowed when the volcano erupted, such a huge underground factory should be able to ensure your safe life, right?" ”

"Of course, the living environment of our volcano factory is the best, and the heat of this volcano is still very strong, if it is an ordinary person. Fortunately, it has now become an extinct volcano. Li Fei said proudly.

"Well, let's build a factory here first, train the mineral deposits here, and extract the materials we need." Tang Hao said.
