Great Qin Shihuang can hear my heart

Less than half an hour.

Surrounded by the guards, the First Emperor arrived at the Construction Department immediately. As soon as he stepped into the Construction Department, he didn't even want to be polite, and walked directly into the test site behind.

Seeing all kinds of experimental equipment used beside him, he couldn't help but asked Mo Zhiyuan beside him curiously: "What are these used for? And this? What is this long thing? "

"Your Majesty, these are graduated cups used to make gunpowder. They are used to measure the proportion of saltpetre in gunpowder. Your Majesty, please don't touch them. You need to use professional gloves to touch them. They may have sulfuric acid on them. The substance of the hand."

"What is sulfuric acid? What is the substance?"

The first emperor was immediately dumbfounded.

He felt the narrowness of his knowledge.

Seeing this, Mo Zhiyuan couldn't help but smiled and said, "Your Majesty, this is from the chemistry class my teacher taught that day."

"Oh, I remembered. When he was messing with you to learn mathematics, I scolded him for messing around. I didn't expect that the later chemistry would be so useful."

"Hahaha, Your Majesty, Your Majesty, you don't know how knowledgeable your teacher is. This long thing is a ruler, which is used to measure the length. When making paper before, thanks to this measurement, it is guaranteed. Neatly sized paper."

"Oh, it turns out to be a measuring tool, and these little cups are tools for objects that are not easy to measure..."

At this time, the first emperor had already been detached.

He felt that he was really illiterate, why didn't he understand anything?

correct.

The construction department seems to have published his mathematics knowledge manual. I will take a copy later to see if I can study and study, otherwise I will look like a fool in front of this group of people.

At this time, Li Lin, who was preparing for the battle in Chenjun, didn't know his mathematics knowledge at all, and Mo Zhiyuan, a bad old man, compiled it into a book and published it.

Of course, Physics and Chemistry were published accordingly.

Including what Li Lin said to them on weekdays.

Mo Zhiyuan also sent people to organize and publish the Analects according to the style of the Analects.

As a result, Confucian disciples and Legalist disciples feel more and more threatened, and they can't help reporting to the group to keep warm, and to fight against Li Lin's Mo Daxue faction that has now been formed.

"Where's the gunpowder?"

"Your Majesty, this is gunpowder. What exploded just now is the first version of gunpowder. Based on the experiment just now, we have obtained a new result, that is, the explosion of this first version of gunpowder is not stable and not very powerful. , did not blow up the house for this experiment."

"Well, let me see!"

The main purpose of Emperor Shi Huang's visit this time was for gunpowder, and now he saw that the powdered gunpowder did not look like what he had imagined, so he was a little surprised.

"Your Majesty, the reason why gunpowder is called gunpowder is because they are all powder, and they are very similar to crushed herbs, so they are called gunpowder!"

"So that's the case. It seems that some improvements are still needed. I don't know how long it will take to fully use it in actual combat?"

"It will take three months if it is fast, and half a year if it is slow."

"So fast?"

The first emperor was a little surprised. Obviously, he was full of surprises at the speed at which gunpowder could be used in actual combat within half a year.

"Your Majesty, as soon as the first version comes out, the subsequent changes will be nothing more than proportional changes. In this way, the natural time will be fast!"

"Yeah! It makes sense, Mo Zhiyuan, work hard, and when the gunpowder is completely produced, I will make you a great official!"

"Your Majesty, Your Majesty, it is absolutely forbidden. These are the masterpieces of my mentor. I am just waiting to put my mentor's idea into practice. If your majesty insists on rewarding villains, why not formally establish your mentor's school, just like Fa family, like Confucianism."

"Good suggestion, I will discuss it with Li Lin when he comes back."

The First Emperor nodded and left the Construction Department very satisfied.

All of a sudden, in the entire city of Xianyang, all officials, big and small, were talking about the loud noise in the construction department. It seemed that everyone's attention was really drawn to the gunpowder.

Chapter 121 Fusu's Shock

"Meng Yin, do you know what caused the loud noise just now?"

"Young master, it's gunpowder!"

"gunpowder?"

Fusu stared wide-eyed, with a dazed expression, as if he had never heard the word gunpowder.

"Yes, my lord, it is gunpowder, one of the four great inventions that Li Xiang worked out in the past. It was established together with papermaking, printing and compass. Now that the other three great inventions have come out, this gunpowder is also starting today. It's an experiment."

"Gunpowder...Gunpowder that can make such a loud noise, as loud as thunder..."

Fusu muttered to himself, and then asked: "What can this gunpowder be used for?"

"My lord, it is said that this gunpowder can be used on the battlefield, and it can be made into a powerful thunderbolt that can blow through the city walls..."

Meng Yin also came from hearsay.

He himself is only half-knowledgeable.

For a rare thing like gunpowder, he really didn't know how to express it in words.

"My lord, Li Lin's gunpowder is fine. The most urgent thing now is to abolish all of Li Lin's new laws and let him step down from the prime minister's throne!"

Seeing that Fusu was showing signs of wavering, Fu Sheng immediately ran over to persuade him.

"Hey, Mr. Fu, you are being polite. Although Li Lin is at fault, these four great inventions are of great benefit to us. That paper, Fu Su can't put it down!"

Fusu waved his hand.

He and Li Lin have political disagreements, but he will not completely deny everything Li Lin has done just because of their political disagreements.

Four Great Inventions.

Isn't it good?

Paper replaced bamboo slips.

The compass replaces the clunky Sinan.

Printing has completely changed the traditional cloth printing technology. Even after the paper comes out, books are printed uniformly, and there is no need to rely on a lot of manpower to repeat the work of copying.

Saved a lot of time.

Now the gunpowder looks like it's about to show up.

It is estimated that there will be a great change in the pattern of the future battlefield.
