Chapter Twenty-Four: The legs are a little weak "Father, this is the material formula of cement, and there are too many design drawings of the cement kiln, so my father can let people take it themselves."
Li Zhen took out a piece of paper, on which was written a few paragraphs, his cement is at least primary cement, but there are not so many messy precautions, the formula is mainly written is the material name and ratio of cement, and then the time of high-temperature calcination and a little precautions, it is very simple.
"It's that simple?"
Li Shimin also thinks it's too simple, but it's also a treasure that benefits the country and the people, why is there only a few words?
"But it's such a simple recipe, it took the child months and nearly 10,000 yuan to come up with."
Speaking of this, Li Zhen said deliberately: "By the way, did you reimburse the child for this money?"
” "Go, go, you're embarrassed to ask your father for money."
Li Shimin is a good person, but he can't mention money to him: "Seeing that the army is about to go to war, and the treasury is empty, the rats can starve to death, and my father doesn't know where to get the money, do you want me to reimburse me?"
Besides, you have to get nearly a thousand pieces of gold and silver every day, and your father doesn't collect taxes from you. ” Speaking of this, Li Shimin felt a pain in his liver, he knew that Li Zhen could make money so much, what kind of big-tailed wolf did he pretend?
What taxes are exempted?
"However, the child's tax exemption was obtained by the child with a horseshoe to your father."
Li Zhen blinked her eyes and pretended to be ignorant: "Could it be that Father, you are jealous of your child's income, and you are ready to discredit and take back the tax exemption?"
” "Of course not."
Although his heart was dripping with blood, Li Shimin pretended to be generous and said: "You have no jokes, how can you take back what your father should have promised to Zhen'er?"
Besides, you will earn a thousand yuan a day, and your father can't look down on it. ” "Hee-hee, thank you father."
Li Zhen breathed a sigh of relief in her heart, and then pulled off a handful of his beard, and Li Shimin, who was in pain, grinned.
"Okay, the matter of cement in your heart has been discussed, you should show your father the power of the grenade, right?"
Li Shimin hasn't forgotten the grenade.
"I won't disappoint my father."
Li Shimin hugged Li Zhen to a lawn: "Is it okay here?"
” "Performing in the palace?
Father, let's go to Nanshan for experiments, right?
"Li Zhen is embarrassed, although I have heard it myself, it is obvious that Li Shimin did not take the grenade to heart.
It's just that Li Shimin doesn't know, but Li Zhen knows too well how much energy a grenade made of ammonium nitrate explosives can produce when it explodes, and demonstrating it in the palace will scare those pampered beauties and princes to death.
"It's okay, just here."
Li Shimin was arrogant: "It's just right, there are nothing new in the palace during this time, so let's take this thing to refresh my father." ” "I'll go ......"
Li Zhen was directly speechless, and took a hand to refresh the gods, father, you are really enough, just that, since you are not afraid, what am I afraid of?
Li Zhen also let it go: "It's okay, but for the sake of safety, you have to plug your ears." ” "Plugging your ears?
No, my father, I have been fighting all my life, what have I never seen?
A mere grenade can't scare my father.
Li Shimin waved his hand magnificently, in his opinion, a little noise, what is it?
“......
All right.
"Li Zhen doesn't care, anyway, this open place can't kill anyone, at most, it's just a bit louder.
"Father, we stand here."
It just so happened that there was a half-high stone wall on the edge of the lawn, and Li Zhen pulled Li Shimin behind the stone wall - although it was certain that the grenade could not hurt anyone, but just in case, some protection had to be done.
"Okay, okay this time?"
Li Shimin felt that Li Zhen's affairs were a little more, wasn't it just a big firecracker, as for being so careful?
"That's it."
Li Zhen gently pulled out the safety pin, pressed the reed violently, and then threw the grenade out with the momentum of the thunderous ringing bell of the bright moon, and then put Li Shimin to the ground, and he poked out his head to observe the situation.
After three seconds......
"Boom!"
There was a thunderclap in the clear sky, like a thunderbolt descending into the world, and the flames rose from the ground, mixed with gravel and earth chips, and the farthest even fell on Li Zhen's body.
After the movement passed, Li Zhencai pulled up Li Shimin: "Father, are you okay?"
” "Hmm!!!
Free novels bring you joy and joy ---> storyskyline.net
It's okay.
Li Shimin shook the crumbs on his head, and then sighed: "Oh my God, why is it so loud?"
” "It's still small."
Li Zhen mixed Li Shimin: "If it is made into an explosive package, the walls of our Chang'an City will not be able to withstand it, let's go over and see the specific effect." ” "Wait a minute, wait a minute, my father's legs are a little soft."
Li Shimin supported half of his body on Li Zhen, if Li Zhen didn't have some strength, he would have been overwhelmed.
"I said that it was you who made my father plug his ears, but you didn't listen."
Li Zhen blamed in her mouth, but laughed in her heart, let you underestimate people, this time you suffered, right?
"Yes, yes, it's my father's fault."
Li Shimin admitted his mistake with a wry smile: "Father never thought that there would be an artifact with such a huge voice in this world. ” "Hehe, it's not just loud."
Feeling that Li Shimin had almost recovered, Li Zhen pulled Li Shimin to the explosion: "Father, you better feel it yourself." ” "This ......
Could it be that this is the result of the explosion just now?
Li Shimin looked at the pit that was still smoking in disbelief, saying that the purified ammonium nitrate explosives were indeed powerful enough, and a grenade charge was a little more than one or two (between 50 grams and 70 grams), and it actually blew up a big hole nearly one foot deep and two feet wide, which was really worthy of his investment of ten times (Li Zhen's cost of making grenades).
"Or else?"
Li Zhen asked rhetorically: "In addition to the child's grenade, did anything else appear here just now?"
” "But this power ......"
Li Shimin still couldn't believe it.
"Otherwise, if my father wants to try another one, the child still has it here."
Li Zhen pulled out another grenade.
"Zhen'er, such a dangerous thing, you put it in your arms?
It's just too dangerous.
Li Shimin took the grenade: "It's better to let your father save it for you, it's a big deal that your father will give you another ten taels of gold." ” What about the "......" face?
is so blatantly robbing his son's things, Li Shimin, what about your dignity as an emperor?
"Father, even if you have a sample, you can't study it."
Li Zhen looked at Li Shimin silently and directly broke his mind.
"Zhen'er, you misunderstood......"
Li Shimin was told what was going on, his face was embarrassed, and he wanted to explain something in a panic.
But Li Zhen didn't listen to his explanation, took out another grenade, dismantled it in front of Li Shimin, pointed to the explosives wrapped together, and said: "This kind of explosive is the key to the explosion of the grenade, if there is no formula for explosives, even if you can imitate the shell of the grenade, what is the use?"
” "Uh......
I see.
Li Shimin carefully touched the explosives: "It's nothing special, it's just that the taste is a little rushed, a bit like the smell of urine." ” "Father guessed correctly, there is a thing in this ammonium nitrate explosive that requires urine to be refined."
Li Zhen did not deny it either.
"However, compared to the composition of ammonium nitrate explosives, there is another problem that you should be more worried about now, father."
Speaking of this, Li Zhen smiled evilly.
"What's the problem?"
Li Shimin asked subconsciously.
"Queen Mother......"
Li Zhen let out a terrible scream, and then threw herself in one direction......
