When closing the bones, Chen Wangping found that there were some radioactive residues on the hands and forearms of these bones.

It can be seen that the process of their research on green ore, that is, uranium ore, was not so smooth, and many people's bodies were damaged.

While gathering, Tang Xihe came over with a stone slab and handed it to Chen Wangping: "This is found on a single desk. Look at the status of the desk owner, the quality of the stone slab is very high, and the words on it are interesting, you can see."

Chen Wangping turned his head and looked at it. The stone slab said: "Xiaopang, I can't take care of you anymore. Fortunately, I added enough nutrient solution last night. I hope you can hold on for more time until the large army comes over and you will win. Comrades who saw this sentence hope you can go to the research office directly below my office to rescue Xiaopang as soon as possible. It has a great effect. I hope you will treat it well."

"Little Pang? The research institute directly below?"

Chen Wangping took the stone slab and looked at the ground, activated the mineral detector and checked the terrain, and found that there was really a huge space underneath."

Tang Xihe guessed: "This little fat man should be his pet, or one of the research projects here. He must have died after more than three hundred years, but if he studied its body, he might have gained something."

Chen Wangping nodded, "Let's go over and see later. I will dig out the uranium ore purification device under Director Li's desk first."

The two of them gathered all the bones on their hands, then moved the desk, took out a pickaxe and smashed it.

Soon, the concrete cracked and exposed a metal box.

Chen Wangping reached out and raised his hand, but he couldn't lift it. He didn't know what made the metal box. It was extremely heavy and could not even lift it.

Fortunately, he has an exoskeleton module.

After activation, hook your hands on both sides, and the exoskeleton slowly rose, easily lifting the metal box out of the groove.

There is no chain on the buckle of the metal box. Obviously, Director Li knew that the person who could find the box would definitely be able to unlock the lock, so there was no need to add any faults.

After lifting the metal box, Chen Wangping nodded with satisfaction.

He saw the thick green system light, proving that the machine is still usable.

If you look closely, the machine is about the size of a dining table, with layers of oil cloth wrapped on it, and there is also cotton cloth on the side to absorb vibration buffers. There are no traces of insect damage on it, which can be seen very important.

Chen Wangping reached out to put it in the storage compartment and checked the attributes:

【Uranium ore enrichment device☆☆】

【Usage: Mining device】

【Enrichment range: radius twenty meters】

【Energy consumption: 100kW】

【Durability: 3420/10000】

[Special effect-enrichment: This device can enrich uranium ore within the radiation radius, consume ordinary uranium ore, and increase the content of uranium 235 in uranium rich ore]

[Note: This is the crystallization of wisdom from the Seventh Institute]

That's it!

Chen Wangping admired it very much. With this thing, whether it is building a nuclear bomb or a nuclear reactor, it can save time greatly.

It's simply a magical tool.

Moreover, from Tang Xihe's description, it was detonated five years later that the world-destroying bomb that might be a nuclear bomb was detonated, and this thing was of great significance.

Tang Xihe saw Chen Wangping's happy look and was also very happy. She ran to another desk excitedly, aimed at the ground and blasted the little fire python, and smashed it open.

After the ground cracked, a dark hole appeared.

Chen Wangping asked Tang Xihe to throw a little flame in and found that the flame could burn normally, proving that it was not completely closed inside.

After expanding the hole, the two jumped down.

After landing, I looked around with the light and found that there was no bone inside. There were various machines for research around me. There was a large fully enclosed metal cylinder ten meters high and five meters thick in the middle.

The two of them looked for clues separately. Tang Xi and the others looked around and found a desk that was exactly the same as the one above. They walked over and flipped through it, and found another stone slab on the desktop. She greeted Chen Wangping and said, "Look, there are words here."

Chen Wangping heard the voice and found that the handwriting on it was similar to the previous one, obviously written by one person:

"The expected renovation time for Xiaopang this time is three months. I hope it can hold on. The newly transferred LD alloy on it is really good. I have to hide the dissolved agent. If it is lost and cannot be opened, it will be troublesome."

"Do you want to record the location? If you forget it, it will be troublesome."

"But if I write it down, it may be seen by others. Forget it, I have such a good memory and I shouldn't forget it!"

...

"Don't you! Where did I put the LD alloy dissolver? Xiaopang! Wait until I save you!"

There are some scratch marks on the last line of characters and some flowers.

After looking at the stone slab, Chen Wangping and Tang Xihe were both speechless.

Tang Xihe pointed to the large cylinder next to him and said, "Is this thing the LD alloy he mentioned? Xiaopang is inside?"

Chen Wangping said: "It should be, there are no other metal products here."

Tang Xihe turned around and condensed the fire python and said, "Then I'll try it first and see if it can explode."

Chen Wangping stared at the stone slab, with a vague impression, he was recalling it.

Seeing that he didn't say anything, Tang Xihe thought he had made a mistake and raised his hand to condense dozens of fire pythons. With a wave of his hand, the fire python squirted towards the large cylinder.

"Bang bang bang"

Fires splashed everywhere in the cave, and there was a lot of noise.

But when the fire python dissipated, there were only some black marks on the large cylinder, and there was no sign of breaking it.

Tang Xihe said in surprise: "There is such a good performance? If I continue to move, even the steel plate will deform." After saying that, she said helplessly: "Brother Ping, it seems that we can't open this thing today. I have never heard of LD alloy dissolvers. More than three hundred years have passed, where can I find it?"

Chen Wangping turned around and smiled, turned his hand and took out a bottle and said, "Don't worry, I have it."

He thought about it just now, and finally thought that in addition to the key, he also obtained the Lei Zhu seeds and this LD alloy dissolver from Wang Jin's relics.

I didn't expect it to be used here.

Fortunately, the module armor added a lot of storage spaces, otherwise he might have left the cleaning at home when he set off this time.

Tang Xihe looked at the LD alloy dissolver and was eager to try it, "Or I will use it? This thing should be similar to applying skin care cream."

Chen Wangping pointed to the stone slab and said, "No, you see, the stone slab says that the LD alloy has strong protection power, and there may be residual nutrient solution inside, which may erupt after dissolving. Let's call the Golden Eagle to come over and start to dissolve from above."

After a while, the two of them squatted in the previous office and looked down from the entrance of the cave.
Chapter completed!
