Dongyang group, somewhere in a small courtyard.

At this moment, the royal magnate was helping Li Tianzhi with some strange things.

At this time, he covered his mouth and nose, and held a bunch of things in his hands.

"My lord, why are you honestly asking me to go to the toilet to get these things?"

"You don't understand this, this is called saltpeter!" Li

Tian smiled, and finally held it into his hands as a treasure.

Generally speaking, this thing will only grow in dark and damp toilets, and occasionally some will appear on old walls.

In particular, it will appear on some bricks and tiles, and the white crystals on them are exactly what Li Tian needs.

"When we can find the saltpeter vein afterwards, we won't have to work so hard to pull it out of the toilet like this.

Li Tian said with a smile, and then untied a cloth from his waist, with sulfur in his pocket.

"I'm already running the 19th toilet. "

My lord, can you not let me go next time?" said

Wang Quangui with a helpless expression.

"It's okay, after all, you are a great talent, and it is indeed a grievance to let you do it, so be it, you spend money to let others do it, I think, there should be many people who are willing to do it.

As soon as these words came out, the king and magnate rolled their eyes.

"Two days ago, I said, let's go out for a meal together when you're idle and bored, you have to say that the restaurant outside is expensive, anyway, stay here, why don't you save some money for food and lodging, and now you tell me that you are willing to

spend money to let others get it?"

"Hehe, the province should spend flowers, I am about to master this recipe now, once I control it, for the sake of efficiency, I can only spend some money to let people help get these things."

Li Tian couldn't help but laugh.

As he spoke, Li Tian mixed the sulfur and the white saltpeter.

Finally, the charcoal from the nearby stove is taken out, cooled and crushed into powder, and sprinkled on top.

At this moment, Li Tian held his breath and played carefully.

When everything was ready, I recently took a small wooden stick, lit it, and threw it away.

The moment the three mixtures came out of this flame, they exploded in an instant, and a burst of fire rose into the sky, and even the ground was clearly visible, the dust after the burning.

"It's a success! It's finally a success!" Li

Tian jumped up happily.

There was a hint of madness in his eyes, as if he had discovered something extraordinary.

"My lord, don't sell medicine in the gourd, hide it, tell me quickly, what the hell is this

!" "It can burn!"

The

eyes of the royal magnate were full of incredulity.

"This is a secret, no one can tell it for the time being!" Li Tian smiled, and finally turned his head and continued.

"By the way, let me go to the iron shop to get an iron ball, I want this iron ball to be hollow

!" "Now!" "Yes

! It's a hundred thousand urgent, hurry up!"

Li

Tian hurriedly spoke.

When the king saw Li Tian like this, he naturally didn't dare, he was the slightest bit lazy, so he hurriedly went to me to do it.

Watching Wang Changgui leave, Li Tian was full of smiles.

"The simplest black powder is finally done, and the next step is to make the simple version of the grenade.

Li Tian suddenly got inspiration from Elder Guan's side, so he thought of the lethal weapon of grenade.

Of course, the grenades it produces are definitely much worse than modern grenades.

After all, black powder is naturally inferior to modern TNT gunpowder.

But their chemical composition is extremely similar.

After continuous experimentation, Li Tian was finally able to successfully test the best formula.

That's 10% sulfur, 15% charcoal, and 75% saltpeter.

However, these things are not very pure, and when wet, they can affect the detonation very much.

So these days, Li Tian has thought of a lot of ways and finally came up with it, that is, purification.

The charcoal is rolled into powder, the sulphur is dissolved, and then the water is filtered incessantly, and then the gouache is evaporated.

And saltpeter is also the same.

After all, I don't know much about chemical displacement reactions.

Therefore, only the simplest purification method can be used.

"Now everything is ready, all we need is the east wind.

Li Tian said with joy in his heart.

Then, as if thinking of something, Li Tian groped out some silver from his arms and walked straight out of the courtyard.

......

Chen Yangqun, although there are many troubled streets, there are also many beggars living on the streets.

There are often robberies in remote alleys.

And Li Tian happened to be passing by the mouth of the alley at this moment.

Not far away, one after another beggars in ragged clothes, holding a dog-beating stick in their hands, and a broken bowl in front of them, with a hint of cunning and greed in their eyes.

However, they know that some people cannot be offended casually.

Otherwise, it will be easy to run out of food, but some people, as long as they can act at the opportunity, it doesn't matter if they rob it.

Anyway, they still have some status as a beggar, and they can't take on too big things.

Even the county government has been there many times.

"Your eyes have been staring at the silver in my hand, why do you want it so much?"

Li Tian walked around the alley twice, and found that those beggars had been staring at him, so he didn't turn his head, and suddenly had an idea in his heart.

As soon as these words came out, several old beggars walked to the side. Judging from their years of experience as beggars, Li Tian is estimated to have come to find fault, and more is better than less.

"Don't be in a hurry to go, I haven't finished my words yet, if you want the silver in my hand, I can't give it to you!"

As he spoke, Li Tian took out a lot of silver from his cuffs.

These beggars have never seen so much money, and on weekdays, they only get some copper coins at most, and occasionally some broken silver, but Li Tian has these big ingots in his hands.

It's not an ordinary big clan, but it won't need ten taels of silver.

"Something

!" "It's normal for you to sleep in dark and damp temples like that, but I think you've found a layer of white stuff

on the walls!" "This kind of thing is also on the walls of the toilets!"

"If you can get your hands on these things! I'll pay you by weight."

As soon as these words came out, all the beggars present were stunned, and some even picked out their ears, and they thought they had heard it wrong.

Somebody wants that thing

?" "Are you sure about this boy?"

"Sure, I'll live in the third courtyard to the east!"

"But, if you have to say it, it must be the things I need, and don't fool me with other stuff mixed in! As he

spoke, Li Tian's iron arm technique was instantly turned on, and he threw it the blue bricks and stones on the side.

Click

! The stone shattered!

Many beggars were a little frightened, and if this were to hit them, they would definitely break their bones.
