The northern border of the Kingdom of Wallaine, Fort Lemlos.

"What are you doing with this thing, put it down, it's very corrosive!" Carolon shouted at Murphy, who was holding the sulfuric acid jar in a daze.

"Lord Carolen, I have a new idea here, I don't know if you're interested?" Murphy relieved, looked down at the sulfuric acid in his arms, and raised his head to Carolen.

He knew that as long as he had a new idea, these words would make him Carolin obedient.

"Tell me about it!" Carolen's soul fire trembled, and she wanted to take Murphy to the lab immediately.

"It has something to do with alchemy. ”

"Alchemy? Forget it, this has touched my blind spot. Hearing that it was related to alchemy, the soul fire that lit up in Carolen's eyes dimmed a little, and she seemed to be a little disappointed.

"Mr. Carolon, do you want to listen to what Your Highness has to say, maybe there is something I need your help with. Luo Che Bass said with his hand on the side.

When he heard the word alchemy, his whole body became excited, but after thinking about it, why did His Highness bring an alchemy blind person to participate in the matter of alchemy?

"Yes, this new experiment really needs your help to succeed, and you can't do without it. Murphy shook his head mysteriously, looking at Carolon with an inquiring look in his eyes.

"Tell me what kind of experiment it was?" said Carolen's hand, raising slightly, motioning for Murphy to continue.

"Actually, it's an improved version of black powder, which I call yellow explosives. Murphy placed the sulfuric acid in his arms on the table.

"This explosive requires sulfuric acid and nitric acid, ah, that is, strong water, and the combination of the two is extremely powerful but very stable, how to say. A basin-sized fireball condensed in Murphy's hand, "Such a large piece of yellow explosives could blow our walls down." ”

Carolon and Roche Bass were a little surprised, if it was really as Murphy said, then the practical value of this yellow explosive would be extremely great.

"It's hard to believe, but if you want strong water, can't you just throw saltpeter and alum into the cauldron and boil it?" Carolon scratched her skull and asked Murphy with some confusion.

"No, no, no, what you get is a mixture of sulfuric acid, nitric acid and salt, which can only be used to make primitive explosives, not the high concentration of nitric acid I want, and the other method is too wasteful, and every time I will waste a pot. Murphy bluntly vetoed a pot of nitric acid.

"Okay, so what do you need me to do?" Carolon spread her hands helplessly, "I don't know anything about alchemy. ”

"Actually, your job is very simple, it's a bit blue-consuming, ah-no, mana-consuming. Murphy shrugged, "I'll tell you more about the specific process later, this experiment can start now, just need to prepare the materials." ”

He took a closer look at the laboratory of Luo Chebas, and saw that the laboratory table, the distillation table, and all kinds of equipment were all available, and he was also relieved.

"You can hire an apprentice to watch over the lead room in the future, as long as you can continue to produce sulfuric acid, and there will be no great danger if you take good protection measures. ”

Murphy looked at the huge lead room still at work over there, picked up the first pot of concentrated sulfuric acid produced, and walked into the lab with Rochebas and Carolen.

"Your Excellency, your job is simple, just keep discharging. Upon entering the lab, Murphy put the sulfuric acid on the bench and turned to Carolen.

"Discharge, what are you going to make me electrify?" Two blue magic circles instantly appeared on Carolen's hands, and electric lights continued to flash.

"Electric air is fine, and then put a basin of water underneath to get dilute nitric acid. Murphy brought a basin of water and placed it on the ground, "By the way, remember to narrow down the electrolysis to the size of this basin, the compounds produced by electrolysis will be toxic." ”

"Just kidding, do you think I'm scared of that bit of toxicity?" Carolon scoffed, ignoring Murphy.

"Flowing water, drainage!"

"Thunder Arclight!"

I saw that his hands were full of lightning, and two thick arcs of electricity burst out of the void, constantly shocking the air in front of him, and there was a "crackling" electric shock, and the electrolyzed material flew towards the basin of water along the drainage magic.

I have to admire the lich's magic reserves, Carolon continued to be electrocuted for three minutes, and she didn't show any fatigue, if it was Murphy, it was estimated that she would be lying down now.

"Your Excellency, you can stop, what I want has already come out. Murphy quickly told Carolon to stop, if it weren't for the open doors and windows to let the wind out, the room would now be full of electrolyzed mixtures.

"Is that what you want?" said Carolon as she stopped her hand and pointed to the reddish-brown gas that had fallen into the water to Murphy.

"That's right. Murphy nodded, "These gases melt into the water and turn into nitric acid." ”

This method is called the arc to nitric acid method, and the nitrogen oxides produced by the arc method are mainly nitric oxides, mainly nitric oxide, and nitric oxide is insoluble in water.

The water solubility of nitrogen dioxide is relatively good, and dilute nitric acid and nitric oxide can be obtained by reacting with water when it enters water.

The dilute nitric acid is finely distilled, and the concentrated sulfuric acid that has just been prepared is added as a dehydrating agent halfway through, and a high concentration of concentrated nitric acid can be obtained.

As soon as he said it, Murphy brought the pot of dilute nitric acid to the distillation table and followed the above steps in turn, but after a while, he got enough concentration of concentrated nitric acid.

"That's it, what about the yellow explosives?" Carolon was a little incredulous, thinking that it was some kind of big experiment, and he was happy in vain.

"That's what is going to make yellow explosives, nitric acid and sulfuric acid, and it's all in high concentrations. With two jars in hand, Murphy left the distillation table and walked to the test bench.

"But those two things aren't enough. Murphy picked up a bottle of colorless, clear liquid on the bench, "We need this too, toluene." ”

That's right, toluene is the thing on Earth that is feared by the world and must be checked when renovating a new house, which is what Murphy accidentally saw in Lotchebus's laboratory last time, which also strengthened his belief in creating yellow explosives.

Concentrated sulfuric acid, concentrated nitric acid and toluene are mixed in proportion to react to form a trinitrotoluene substance, which is yellow granules.

"That's it!" Murphy picked up the yellow granular material from the bottle and shook it.

This thing is yellow dynamite, and it has a more well-known name - TNT.
