I can extract health points

"Are the reserves of this black crystal very large?" Li Xiao asked. If the reserves are small and difficult to mine, it may not be able to qualitatively improve the Black Eagle Empire's strength in the short term.

"It's very huge. The permafrost layer at the mine site where Black Crystal was first discovered is hundreds of meters deep and the area hundreds of kilometers wide is almost entirely covered with Black Crystal minerals."

hiss……

Li Xiao took a breath of cold air. It was hundreds of meters deep and more than a hundred kilometers in diameter. What a terrifying amount of mineral deposits this was.

"How many research and development bases does the Black Hawk Empire have like this one?"

"Very many, but they are only responsible for developing various launchers. Only I control the processing technology of the black crystal. Without my craft formula, the black crystal is just a pile of pebbles in their hands."

"Mr. Ma, what are the facilities on the three floors below?"

Li Xiao was still thinking about Mavis's words, but Ling Chao was very worried about their retreat, so he asked hurriedly.

"The fourth underground floor is the living room for the R\u0026D personnel, the fifth underground floor is the material stacking area, and is also the storage area for the black crystal ore. The sixth underground floor is directly connected to the tunnel of Hailan Port, fifty kilometers away.

From there, they transported the black quartz ore in by freight train, and then shipped the finished product out, including the base's personnel and logistics supplies. "

"It turns out there is a railway underground!"

Li Xiao suddenly realized that no wonder there were no roads in the canyon on the satellite map, but infantry tanks could appear in the canyon.

"Mr. Mavis, the Black Hawk Empire cruelly oppresses civilians and rules the world with iron blood. There is no need for you to work for it anymore. Why don't I take you out of here and provide you with a new safe and stable base to continue your research and development work!"

Mavis smiled faintly: "Whether it's the Black Hawk Empire or you aliens, in the end they just want to use the weapons I made to slaughter the entire world."

Li Xiao did not deny it and said bluntly: "Yes, I do not deny our purpose, but at least we will not oppress the common people and extract their wealth and labor force."

"You don't need to explain. I have already prepared to destroy Mo Jing's information. Even if you take me away by force, it will be of no use."

"So you are planning to give up your wife and daughter?" Li Xiao suddenly changed the topic.

Sure enough, Mavis suddenly fell silent after hearing Li Xiao's words, and his face became painful.

"They, I haven't seen my wife and daughter for five years. I don't know if they are still doing well..."

Mavis choked with sobs, tears falling down heavily.

Li Xiao breathed a sigh of relief. It seemed that his guess was correct. The Black Eagle Empire must have kidnapped his wife and daughter as a condition for blackmailing Mavis into working.

This may be the only weakness of this weapons development expert.

"Mr. Ma, or I should call you Dr. Ma. If you are willing to take all the information with me, I swear that I will rescue your wife and daughter."

"Follow you? Why should I trust you? You don't even know where my wife and children are imprisoned!"

Li Xiao thought for a while and said: "I think the reason why you have been working for the Black Hawk Empire for a long time is because they let you and your wife and daughter see each other often, although it is more likely that it is just a video call."

Mavis nodded: "Young man, you are very smart! But what can we do?"

"Have you ever saved the video of your phone call with them? I think I might be able to find some clues from it."

"Part of it, but once I leave here, the Black Hawk Empire will kill them mercilessly. No matter what, I won't take the risk!"

Mavis sternly refused. Li Xiao was a little depressed. He finally got here. If he couldn't take away this weapons expert, then his trip would be almost in vain.

Li Xiao had no choice but to resort to his ultimate move.

"Mr. Ma, Dr. Ma, if you continue to stay here to help the Black Eagle Empire create these powerful weapons, then tens of thousands of civilians in the Tianyu Republic and your hometown, the Gama Empire, will die from the guns you developed. Under the gun.

In order to save your wife and daughter, you are unwilling to take risks and try to rescue them, but you have to sacrifice the blood of thousands of compatriots to keep your little family alive!

Are you worthy of becoming a scientist respected by the people? "

"But...this...!!!"

When Mavis heard Li Xiao say this to him, he was speechless and speechless.

Yes, what Li Xiao resorted to was moral kidnapping. Although Li Xiao hated such behavior and it was for his own benefit, this was also a choice he was forced to make.

"Dr. Ma, I promise, if I can't save your wife and daughter after we get out, then I will let you do whatever you want!"

Li Xiao felt that he could not delay it any longer. If the gate was blocked, they might enter the tunnel from Hailan Port to outflank them.

"Hmph! Let me handle it, will you let me kill you?"

"Then why not? As long as we can prevent the Black Hawk Empire's conspiracy, then my life is a trivial matter, even if you hold a machine gun and beat me into a sieve."

Mavis sighed and said helplessly: "Okay, I'll go with you, but I need ten minutes to destroy all the data left here."

"This is no problem!"

Ten minutes later, Li Xiao was waiting for Mavis at the elevator entrance on the fourth floor. He had already changed into a suit and was holding a coded suitcase in his hand.

"Now let's go to the fifth floor, where a batch of supplies needs to be destroyed!"

Mavis entered the elevator with ease, and Li Xiao and the others followed immediately.

When the elevator door on the fifth floor opened, a warehouse of more than a thousand square meters was in sight, with more than half of the space filled with long boxes made of aluminum alloy.

"These long boxes contain crushed black crystals. There are still two million points of them here, enough to make six million rifle black crystal bullets."

"So many!"

Li Xiao walked over. He was thinking that these black crystals had to be mined from the Arctic. Even if he took Mavis back, it would be useless without the raw materials.

Now he doesn't have to worry for at least a while.

So Li Xiao waved his hand, and two million points of black crystals went into his backpack.

Then Mavis came to the other side again. This time, Li Xiao knew that these were black crystal bullets without his introduction, because he had seen the packaging of black crystal bullets on the second floor just now.

"Here are 1.5 million black crystal bullets. We were originally planning to load them and send them off tomorrow. Now they are cheap for you. Of course, there are also 2,000 Destroyer Crystal Energy Guns."

"Great! I've made a lot of money with this."

Now Li Xiao knows why the system sets an unlimited upper limit for a single item in the backpack. If it is like those online games on Blue Star that only give a few hundred grids at most, then there is no point in playing.

In addition to these things, the rest are some rare iron ores for making guns, which only have a few hundred thousand in number. Li Xiao took them all.
