People in Datang have been expelled from school

Chapter 744 Formula
Tie the horses to the cart and put on the reins.

Li Zheng and Daniel left the stables.

After they walked away, Li Jiangshan came to the hut next to the stables, and the door here was also unlocked.

The door is not locked here on weekdays. Walking into this hut, Li Jiangshan came to the table, where Li Zheng just wrote something.

When the ink seeps into the paper, it will leave some sporadic marks, and it will leave some ink marks on the table case.

Taking out a clean piece of paper, Li Jiangshan glued the paper to the table.

After bonding, apply a layer of oil to the paper as thin as a cicada's wing.

Gradually, some handwriting emerged, which was blurred but still clearly visible.

Li Jiangshan observed these handwritings and found some strange symbols.

It looks like text, but it doesn't look like text.

Some are like the mathematical formulas of Jingyang Academy.

But I can't understand it.

Li Jiangshan copied all these characters and symbols as quickly as possible, cleaned up and left quickly.

Leaving the village all the way, Dumb drove the carriage and looked back at Li Zheng.

Li Zheng was still looking at the chemical formula he had written.

"Chang'an Ling, what are we going out this time?"

the tiger asked.

Li Zheng put away the chemical formula he wrote down and said, "Do you still remember the first time we made fireworks?"

Duhu nodded vigorously, "Of course I remember."

Li Zheng said again: "Now it can be used again, so let's go to the old place where we collected saltpeter before."

After finishing speaking, Li Zheng said again: "I'm collecting more useless stones to cover people's eyes and ears."

Gunpowder is a Pandora's box.

After opening it is likely to be out of control.

Once the cold weapon enters the hot weapon, under the huge lethality, the hot weapon will increase the tragic level of the war by several steps.

The war will become more tragic.

Human life will also become more vulnerable under hot weapons.

Gunpowder is the beginning, and the changes of gunpowder will make thermal weapons continue to iterate, which will increase the lethality of thermal weapons step by step.

So that in the future, people have to restrict a certain weapon in exchange for peace.

Of course, I don't want to hand over the gunpowder to Li Shimin now.

People have to have their own cards in life.

Li Shimin is not such a kind person.

If he really wants to fight Li Shimin to the death, his palace will be blown up at worst.

Li Zheng was determined.

Came to a barren mountain, Chang'an is close to Longyou area, the foothills here are very desolate.

There is an old saying, "Saltpeter comes out of the Long Road"

The saltpeter along Guanlong Road has always been relatively abundant.

There is no vegetation growing on this mountain because this mountain is actually a saltpeter mine.

These saltpeters are enough to make tens of thousands of tons of strong gunpowder.

I saw that many villagers here also dig saltpeter here.

Du Hu explained: "Since the people of Chang'an know to use saltpeter to make ice, people often come here to collect saltpeter."

The proportion of saltpeter in gunpowder is not very large.

Li Zheng turned over and jumped off the carriage, and started digging saltpeter with Du Hu.

The villagers are all from around Chang'an, and they don't know that the person who digs saltpeter with them is the one who came up with the formula for making ice with saltpeter.

After Li Zheng and Duo had dug up three bags full of saltpeter and left.

Someone said: "The person who was digging with us just now seems to have seen it somewhere."

The old man on the side laughed and said, "Everyone has one mouth, one nose, and two eyes. Look, everyone has seen it somewhere."

"I actually met that young man just now. It seems to be the day Princess Changle of Chang'an got married."

"Could it be the newly promoted Duke of Jingyang?"

"How is it possible, how could the Duke of Tangtang come here to dig saltpeter."

"It seems to be the Duke of Jingyang County."

……

Just when people were guessing, a eunuch from the palace came on horseback, "Did the Duke of Jingyang come here just now?"

As soon as these words came out, a group of villagers fell silent.

It's really Duke Jinyang.

Li Zheng and Daniel came to a wasteland again, where there was only a field of yellow sand and no crops.

Du Hu glanced back, "Chang'an Ling, there seems to be no one following us."

Li Zheng got out of the carriage and said, "Just dig some sand."

"it is good!"

Dumb followed suit, and looked around vigilantly.

After filling a bag of sand, Dui rode his horse again and let the horse pull the carriage away from here.

Half an hour later, several eunuchs appeared at the place where Li Zheng had just been.

Take out a brush and write down what Li Zheng has done here on a bamboo slip.

Then he walked in the direction Li Zheng left.

That night, Li Shimin was busy finishing the memorial that needed to be approved today.

Wang Ding took the last memorial and said: "Your Majesty, Chang'an ordered to leave Jingyang today."

Li Shimin took the memorial and looked at it.

Wang Ding said in a low voice: "The movements of Chang'an Order are all written in the memorial."

After reading it, Li Shimin was a little puzzled, "Saltpeter, sand, wood, mud..."

"There is still charcoal?"

After reading it, Li Shimin pondered for a long time and asked, "What does Li Zheng want these things for?"

Wang Ding bowed and said: "Return to Your Majesty, Chang'an Ling has already returned to Jingyang with these things. As for what they are used for, he has sent people to investigate. I think there will be news in a few days."

Li Shimin put down the memorial and pondered for a while, "You send someone to dig up the places Li Zheng has been to, and bring me a copy of the same ones."

Wang Ding bowed and said, "Here! Let's make arrangements now."

Li Shimin got up and walked out of the Ganlu Hall, looking at the empty night, thinking about how many things I don't know about Li Zheng.

How does Li Zheng plan to resist the cannibal's Eastern Expedition.

When Li Shimin came to Lizheng Hall, he also saw Li Jiangshan's letter.

Empress Changsun sat aside and combed Gao Yang's hair and said: "This is from Li Jiangshan, I don't know what Li is doing."

Li Shimin looked at the letter suspiciously, and frowned at the words on the paper.

Some of the text in it is understandable, and some of the text is not understandable at all.

Li Shimin looked at it for a long time, but couldn't understand the above formula, "Guanyin maidservant, what kind of words do you think Li Zheng wrote?"

After combing Gao Yang's hair, Gao Yang followed the maid and left.

Empress Changsun said in a low voice: "The concubine can't understand it, why don't you let Kong Yingda see it, maybe Kong Yingda can understand it."

On the second day, Li Shimin had someone send Li Zheng's formulas to the Imperial College.

After the granddaughter got married, Kong Yingda was not in a good mood. The main reason was that he was from a scholarly family who married his granddaughter to the son of a martial artist, and he heard a lot of gossip on the chain of contempt.

Wang Ding handed a volume of letters to Kong Yingda, "Your Majesty ordered this. I don't know if Old Master Kong Yingda knows the words on it."
