"Small pills?" Andy took the little thing and put it in front of his nose and sniffed it, only to smell a strange bitter and sour taste.

"What can this thing do?" Dr. Donald is smiling and confident in his development.

"It's very simple, it's to make the dirty water less dirty.... It allows stolen goods to settle, it also kills parasite eggs and viruses, and most importantly, it eliminates radiation to some extent. ”

"As for how." He pulled out a small box containing some mushrooms that glowed with fluorescent green light.

Andy took a look and found that it was a fairly common glowing mushroom, which was not very large, but it was very adaptable to the harsh environment of high radiation in the wasteland, so it would grow in large clumps in some special areas.

In the thrifty wasteland, this small glowing mushroom is also used as a seasoning or stewed soup because of its unique delicious taste.

But the first thing that a seasoned wasteland man thinks of when he sees this thing is not that it is delicious again, but that it is.... Get out of here, there must be a source of radiation where this thing exists.

Then again, Dr. Donald started to do something for Andy Kop.

"It's this little mushroom, and it's actually quite useful." Dr. Donald pulled out a mushroom from the box, about the size of a person's little finger, with a long, thin dried mushroom underneath and a small umbrella cover on top of it, glowing green throughout, and darker the higher it was facing up.

"We stayed at the Hoover Dam for a short time, but I still didn't give up on continuing my research, and I met a guy there, his name, his name..."

Andy looked at Donald suspiciously.

"So... You forgot to ask him what his name was, right? Dr. Donald's face flushed, visibly ashamed, and he prepared to end the conversation in embarrassment.

"Ahh Yes, in short... The guy was interested in all sorts of messy... Forehead.... He told me about the usefulness of this kind of thing, saying that this fungus has the property of absorbing radiated substances, and that there is an active ingredient inside it, which he calls the absorption factor. After speaking, he nodded slightly and turned his head to leave, but was stopped by Andy.

"Wait, Dr. Donald, this invention of yours.... I don't know what to call it, it's useful stuff. Andy grabbed him, ready to say what he meant.

"The point is, we now need a person to put together the items that the big dome can be used for external sales, which can not only solve everyone's problems, but also benefit the follow-up promotion of tonic ointment, this pill of yours also has high potential, what do you call it?" Dr. Donald lifted his glasses, saying that he didn't name the thing, just called it a water purification pill.

"In fact, boiling dirty water is a very effective way to purify, at least it can kill the pathogens in the water, but it has little effect on radiation, most people can't drink clean water at all, and this cheap pill can help a little." The two exchanged for a while, and Dr. Donald offered to take Andy to collect the materials that the Great Dome could use for trade, although he thought that Dr. Agnes was more suitable for the job, but she was now monitoring Dr. Goddard's health, so Dr. Donald had no choice but to leave.

.......... The two of them came to a large white neat room, which according to the door number indicated to be a large domed medical center, filled with all kinds of tall glass cabinets and high-tech equipment of unknown purpose, storing a large number of containers of sizes that Andy couldn't read the label, and what appeared to be a variety of solvents, pills, and unidentified items soaked in a similar embalming liquid.

"There's a big dome stockpile of medicines, analgesics, sedatives and antibiotics, as well as addiction relievers... Speaking of which, I remember there were some unethical drugs...", Dr. Donald was finished speaking when Andy waved at him to show that he already knew.

"Paul told me... What else? Dr. Donald took Andy to a warehouse-like room next door, which was filled with cardboard boxes.

When you take it apart, it's full of all sorts of things. Andy picks up a plastic bag that looks like a white hazmat suit.

"Although the quality is not particularly good... There are a lot of disposable non-woven clothes left here, maybe someone in the wasteland will like this thing? Looking at the clothes in his hand, Andy only thinks that some quack doctors roaming around the wasteland will like this thing, and wearing it will immediately give people a professional feeling, helping them trick more wasteland patients who don't know the truth into going to the hospital in a hurry.

The other boxes contained gas masks, medical kits, and unopened rubber boots neatly placed together.

The supplies for the medical center that Xian mentioned earlier are now in front of Andy's eyes.

"These can probably be sold for some money, but not enough, there should be more here in the Great Dome, right?" He looked at Dr. Donald expectantly.

But the other party made a difficulty.

"In addition to these... Everything else is rubbish.." After thinking about it for a moment, he tentatively mentioned some items.

"There are some scrapped robot wreckage in the robotics lab in the big dome, probably because of some remnants of some past experiments, and there is still some electronic waste there." Andy listened to it and felt funny, but he knew that the scavengers in the wasteland were a large group, especially in the nearby dog town, where there was a group of people in desperate need of high-tech garbage

"Salvage".

"That's useful, take me to see it!" Ten minutes later, the two came to a laboratory on the second floor, which was quite complicated to plan, Andy even saw a sealed concrete sealed experimental site that could only view the interior through the surveillance camera, which was full of various traces of destruction, bullet marks, black marks of explosions, and terrifying marks caused by violent impacts.

There are scraps scattered all over the site, some of which appear to be the remains of automated attack devices, as well as the originals of some of the robots.

In the center of the field, there is a pile of blackened and scrapped robots, actually piled up in the same place as a hill, surrounded by terrible bullet marks and even craters that look like they have been blown out by direct hits by rockets or something.

"Oh my God, what was this place used for?" Andy looked at the surveillance cameras in disbelief, and he even saw a decapitated human corpse lying in a corner, wearing heavy military protective armor, and not far away a robot with two long knives in both arms.

Dr. Donald had long been surprised by this, and no amount of surprise melted away with habit and familiarity.

"We checked some information by looking through the terminals here, but there is encryption here, and the main control AI... Even the ZAx supercomputer refused to reveal more information, I am afraid that everything here requires the qualification of a high-level military in the old world, or there are amazing hacking methods... In short, we can't do it, we can only rely on speculation. He pointed to the hill of abandoned robots.

"We guess that this is the old world military robot testing ground, and most of them are some dangerous prototypes, they put the robots in this closed field to test their attack ability and resistance to strikes, and there must be a lot of things happening in the process." Andy nodded, but looked at the unattended corpse in the corner, still in disbelief.

"But what are they letting people in for?" Dr. Donald frowned, silent for a moment, and said something cruel.

"Perhaps... Those were also part of the experiments, testing the effectiveness of military robots against human regular armies, presumably armed criminals or soldiers who had been tricked into being white rats... Or was it the security personnel who intervened because of an accident, but were abandoned here because of the chaos caused by the explosion? Now no one knows why. Andy observed for a moment and was convinced that the wreckage left here was something good to sell.

"Maybe we should find a way to get the contents out?"
