Ma Qiang didn't care about Nanlou, who was about to pee his pants, he slowly picked up the stone, observed it carefully, and then waved his hand to remove the steel knife on Nanlou's neck.

"Where did you get this stone?"

A few people in the building class looked at the difficult building in horror, this thing, it can't be some kind of poison, right?

It's hard for you to do this for Wuhuan, it's rare!

Nanlou knelt on the ground with a puff, tears came out, and shouted, "Ming Gong, this is really what I grabbed from Xianbei, saying that they snatched it from a group of savages further north, because it is good-looking, it has always been regarded as a treasure in their tribe." ”

"Little Pony, what is this?" Orange asked, holding on to Lime.

"This should be uranium ore, and it's very pure!" Ma Qiang took out his magnifying glass and began to observe the uranium mine.

"Ore? Oil? Qingcheng thought for a while and asked incomprehensibly, "Then why did you just let Sister Lime lose it, Brother Pony?" ”

"Uranium is a radioactive element, the so-called radioactivity, refers to the element from the unstable nucleus spontaneously emitted rays, this ray is weak or good, if strong, it will be harmful to the human body, light organ lesions, heavy death, and even affect the offspring, so that the offspring become deformed or sterilized." ”

Is it really highly toxic?

Several people in the building class couldn't help but look at the difficult building with admiration.

It's hard to build a man!

In the future, there will definitely be your heroic spirit on Wuhuan Mountain!

"Nanlou, you offer poison and want to poison Duke Ming and his wife, what crime should you be guilty of?" Huang Xu heard Ma Qiang say that this thing was so dangerous, so he angrily drew his knife and prepared to cut down the difficult building on the spot.

Nanlou rolled his eyes and was ready to faint.

It's over, what the hell is this stone is poison!

Ma Qiang shook his hand and smiled, "It's okay, uranium ore is mainly uranium-235 and uranium-238, both of which have a long half-life, grow to almost a wasted age, and the chance of release is very small... That is to say, their poison is released very slowly, so slow that it is difficult to affect people, and I was also concerned about it just now, because although this ore itself is not very harmful, but after the uranium decays, radon will be produced, and the half-life of this radon is only less than four days, this will really be fatal, Huang Xu, let him go, those who don't know are not guilty. ”

Well, although no one understood what Ma Qiang was saying, at least the last sentence was understood.

Nanlou also breathed a sigh of relief, this startled and frightened, his heart was about to stop.

In later generations, because of the fluorescent effect of uranium, some people even used it to make various utensils, but because of its reputation for radiation, few people bought it.

Speaking of which, Ma Qiang has forgotten how long it has been since he has seen uranium mines, but he didn't expect that this time the difficult building was actually delivered.

Ma Qiang didn't think about really letting someone in the Han Dynasty knock a nuclear power plant for him by hand, after all, it's useless to knock it out, where are there so many electrical appliances, let alone knock on the atomic bomb, and no one in this era is qualified to be bombed by this thing.

But this is after all the starting point of nuclear energy, and it is also the hope of mankind to go to the sea of stars in the future.

At least in the era when Ma Qiang came to this world, nuclear fusion was still the only hope for human beings to leave the earth and go to the stars.

At this time, the white smoke on the side came over and sniffed the ore in Ma Qiang's hand, and then the tiger face showed a puzzled expression, and roared at Ma Qiang a few times.

Ma Qiang touched the white smoke and immediately understood the meaning of the white smoke.

"You said you felt the smell of your parents?" Ma Qiang looked at the uranium ore in his hand, you are not a monkey, what does the stone have to do with your parents.

"I think you're too homesick, yes, when I'm done here, I'll take you home, and I don't know what happened to the loess." Ma Qiang rubbed Bai Yan's head and didn't care.

Bai Yan was taken out of the mountains by Ma Qiang back then, but Loess still lived with Sister Tiger and his wife in the mountains.

In a blink of an eye, almost ten years have passed, in fact, according to the life span of a tiger, Bai Yan has reached middle age.

The normal lifespan of a tiger in the wild is actually less than twenty years, and some even enter old age at the age of ten and be killed by opponents, but Bai Yan seems to be really an anomaly, and at the age of nine, it not only has no signs of aging, but also does not even have estrus.

To be precise, Bai Yan seems to be still growing, according to Bai Yan's own words, it can feel that it is still growing, but on the outside, Bai Yan has long since grown, and he doesn't know where it is, but looking at the bulges on both sides of Bai Yan, Ma Qiang thinks that maybe one day, Bai Yan will grow wings and become the legendary Qiqi.

Ma Qiang re-wrapped this ore, which reminded him of many things in that era and made him more determined in his original intention.

He smiled and said, "I like this thing very much, Lord Nanlou, thank you, I will remember this love!" A few old men, I've been waiting for a long time, come, let's talk here. ”

A few old peasants who had been waiting on the side for a long time were let go, and as soon as they saw Ma Qiang, they immediately shouted with joy, "Ming Gong is Ma Envoy?" ”

Ma Qiang smiled, he had been in Changping for so long, and it was normal for some people to remember themselves.

"You know me?"

"It's really Ma Envoy Jun! Back then, there were moth thieves, or Ma Envoy, you help us avenge! ”

"Yes, I remember there was a conference at that time, it was so lively!"

Ma Qiang couldn't help but think back to that year, speaking of which, it was his first battle.

At that time, I wanted to vomit when I saw the corpse.

And now, when I see the battlefield, I have no other reaction than to sigh.

"Uncles, how are your crops this year? Are there any bad officials and bad gentry? Ma Qiang asked.

"Hey, not well." An old farmer shook his head and sighed, "There are fewer and fewer young people in the village, and I don't know when the world will be peaceful." ”

"Yes, although the land is planted, it is not young and strong, so we can only rely on the hard work of us old men, and the yield cannot be high."

Ma Qiang took a look, and sure enough, all three of them were white-haired, and they were at least fifty years old.

"Where's the young man?"

"Hey, before Liu Yuanjun recruited soldiers, the young and strong all went to serve as soldiers, so that our family will have one less mouth and can get some food."

Ma Qiang now finally knows where Liu Yu's 100,000 soldiers and horses came from.

"Ma Envoy, when will this world be stable?"

"Yes, it's been chaos for many years, and your majesty doesn't care about it?"

Ma Qiang arched his hand and said, "Don't worry, there will be no chaos in Youzhou, everyone's life will definitely get better and better, otherwise it will be a long time before your children will come back and reunite with you, but as long as they are willing to be soldiers, I hope you can support them." ”

"Ma Yuanjun, follow you to make contributions, we are all assured!"

"Yes, who doesn't know, you took the people from the Red Star Camp out, many of them have become officials, and now that our children are with you, it's too late for us to be happy!"

Ma Qiang talked to a few old farmers again, learned about the people of Youzhou, and then returned to the road
