This tungsten carbide long knife, which was suddenly named infinite love, was not a simple and casual weapon, it had accompanied Tungsten Clary for thousands of years.

Tungsten metal has high density, high hardness and high melting point. In the face of lava spirits, the girls of the tungsten clan are definitely the main force among the main forces, and tungsten carbide, as a material with a hardness close to the melting point of diamonds and close to 3,000 degrees, is an absolute weapon of war.

Lin Feifei adjusted his center of gravity, his weight was too low, it was easy to lift this weapon, but it was difficult to swing it.

But in any case, this is also a piece of people's hearts, not to mention, although he can't wield it, Lin Feifei has an instinctive liking for this large weapon.

Yes, I just love it!

"Thank you Tungsten Clilly, I will definitely treasure it. Lin Feifei happily put away this tungsten carbide weapon.

"No, no, no, my sister didn't let you treasure it, she wants you to use this weapon to kill the enemy!"

"Okay! I see!" Although Lin Feifei agreed, he really couldn't imagine what kind of enemy needed such a heavy weapon. This feeling of pulling out the weapon, and the weapon has not been thrown out, but it has thrown itself out, is really weird.

It is said that this time a package agreement has been signed between China and the underground city, including the aforementioned special power station, which is also on the agenda. Regarding the return to the surface, the dungeon proposed to build a city deep in the Taklamakan Desert, and the principle was agreed by the state - of course, how this part of the land was leased needs to be supported by details. But there is one detail that is very interesting, when the ambassadors in the local city heard that China has a very large amount of tungsten ore production, they cheered.

Speaking of which, for these ancients, the part other than the soul core can distinguish races, but it is not a very important part, maybe the tungsten tribe may be a very perfect body for them.

After the signing ceremony, the two sides dispersed, and those who should have stayed in the temporary embassy stayed here, while titanium dioxide happily followed Lin Feifei home.

Yes, this is something that has been arranged for a long time. Titanium Dioxide's identity at this time is the dungeon's goodwill ambassador to the People's Republic of China. Her only purpose here is to experience the customs of China and send this information back to the dungeon. And the matter of exchanges between the two countries is completely left to others.

So, under the arrangement of the state, Lin Feifei's family, who had just been quiet for a few days, had another tenant. Of course, unlike other tenants, Titanium Dioxide lives here with a state grant.

Titanium dioxide still has research on China, most things have been heard, and you can get started with a little adaptation. However, it only takes a while for the electromagnetic signals of the human world to get used to, and for them, these electromagnetic waves are like ubiquitous noise, which is particularly annoying. Of course, since she can hear it, she can block it, and that's not a problem.

In the first few days, titanium attacked Lin Feifei day and night, so that Lin Feifei was often entangled by the electric field in the middle of the night, and he couldn't sleep in the second half of the night. However, like everyone who came to this house, the freshness of titanium dioxide did not last long, and she was at home. She discovered something more fun than electric field entanglement, video games.

All old games are new to her!

Lin Feifei originally wanted to pull titanium dioxide to double row with him, but he was quickly pulled away by Meow Xiaoli.

Poor Lin Feifei could only be alone, trudging alone on the road to the king.

It wasn't long before the results of the national investigation arrived, and the people who had instigated the ancients to seize the elixir of immortality had contacted them through an abandoned mine. After careful investigation, the state finally found that person, but that person was just an ordinary person who was hypnotized and brainwashed, and there was no more information in the surrounding area, so the matter gradually faded.

All the way to, today.

On this day, Titanium Dioxide, who was watching a movie, received a message from the embassy in the dungeon, and scientists from the Chinese Academy of Sciences sent a message saying that they had made progress in their research on immortal elixirs, and that this thing not only had no effect on the ancients, but was also very likely to kill the ancients in an instant. The reason is that these miniature nano cells will be stimulated by the internal electric field of the ancients to devour their bodies at the fastest speed, and because the crystals that make up their bodies are pure minerals or metals, without any genetic material, the cells cannot be reorganized, and eventually the body will disintegrate, leaving only a soul core.

This is a serious problem.

Does the mastermind know about this matter, and if so, how much.

Since that incident, the state has put a lot of effort into this direction, but still has not come to a very good conclusion, so this time, the state decided to make a special move.

All the people in the Chinese Academy of Sciences who are involved in this matter collectively take polygraphs.

Eventually, a researcher that no one could have imagined surfaced.

It was the person who drank too much at the beginning, drank the medicine into his stomach by mistake, and then threw up while holding the toilet.

It was fake to drink too much at the beginning, but it was true to drink the wrong medicine, and it was actually intentional to hold the toilet and vomit. Even Lin Feifei's benevolent brother Lu Xiaofei's girlfriend will become an invincible superwoman, which is actually designed by him.

This matter involves his own Ren brother, so Lin Feifei can't ignore it.

Not long after, Lin Feifei entered Beijing alone and came to the detention center where the researcher was being held. This is a place dedicated to imprisoning all kinds of superhumans, whether it is a monk or a demon clan, as long as they are imprisoned here, all power will be suppressed. Lin Feifei didn't understand anything like the so-called formation, anyway, when he saw this researcher who had shaved his head and was wearing prison clothes, the demonic aura on his body was so weak that it was almost imperceptible.

The warden here has already been greeted and sent an instructor to follow Lin Feifei, and when he can see Lin Feifei, this instructor is quite excited, shaking hands with Lin Feifei and the whole person is trembling. It can be seen that he really wants to ask about Meow Xiaoli, but he doesn't dare to ask, and he is very entangled.

"Here is his confession, and there is also a video of the interrogation, you can watch it slowly. The instructor in the monitoring room said.

"Thank you, you're busy, you don't have to take care of me. Lin Feifei said.

The researcher was very cooperative with the interrogation, asking what to say, and the conditioning ideas were very clear. He doesn't beat around the bush when he speaks, and explains the time, place and events very clearly. But this made many old criminal investigators very suspicious, they had never heard of a prisoner who would cooperate so honestly, and it seemed that he was neither afraid nor impulsive, his face was full of indifference, which was strange. And, most bizarrely, when asked about motives, he replied: "There is no motive." ”

This is impossible, people have a motive for doing anything, even if it is just to kill time because of boredom, this is considered a motive. Humans are not the kind of single-celled animals that rely on instinct to survive, and such a complex thing is definitely not something that can be solved by instinct.

So, all the interrogations got stuck at this point.

It took a few hours for Lin Feifei to read everything through, and he decided to meet the researcher himself.

He had to figure out what this man was hiding.
