After receiving Li Er's strong support, Li Chengqian returned to the East Palace and set about building an academy of sciences next to the Chongwen Pavilion. 35xs

In the future, this academy will not only study new weapons, but also research on the production of science and technology related to agriculture, as well as technological research in handicrafts.

Once the venue is available, the next step is to recruit people who love scientific research.

After half a year, the Academy of Sciences recruited more than 60 scientific talents, all of whom were carefully selected.

In the past six months, the prince has not been idle, and according to his limited memory, he has compiled a scientific research encyclopedia for these scientific researchers to read.

Not only that, Li Chengqian also printed a copy of the agricultural encyclopedia "Qi Min Yao Shu" in the Northern Wei Dynasty and put it in the library of scientists.

And the three masterpieces of "Mengxi Writings", "The Complete Book of Agricultural Administration", and "Heavenly Creations" were also written out silently according to memory.

Before the crossing, Li Chengqian would look through these books when he was bored, so he remembered these three books deeply.

It is not difficult to write out these three books silently, but the difficulty is that although I have read these three books, it is good to be able to remember most of them!

The age of these three books is different, "Mengxi Notes" was written in the Northern Song Dynasty, and "The Complete Book of Agricultural Administration" and "Tiangong Kaiwu" are products of the Ming Dynasty.

The main purpose of the Academy of Sciences is to learn scientific knowledge and conduct scientific debates, which are theories on paper. Flash Dance

The real scientific research experiments are outside the Academy of Sciences, and agricultural research is to work in the fields with the aim of how to increase grain production, such as fertilization, water conservancy, reclamation, etc., and make academic reports on this.

Handicraft production technology and process equipment, etc., research and improvement, as well as some production organization experience.

All these must benefit the people and are closely related to life, and the combination of theory and practice can make great progress in scientific research.

The research on explosives was carried out in a hidden place in a large mountain outside Chang'an City to be used as an experimental base.

After all, this explosive is a dangerous thing, and if it is studied in Chang'an City, once the explosion returns, many people will die, and it is easy to injure innocents.

So it can only be transferred to a secret base outside the city for experimental operations.

In addition to studying "Heavenly Creations" and writing feasible plans in the academy every day, the students in charge of this research in the academy must also go to this base to conduct practical experiments.

The research of explosives is progressing quite rapidly, and these are the spirit of dedicating everything to scientific research with this passionate heart.

The main ones didn't know, or even didn't know the power of the explosives, so they didn't have any scruples about researching the explosives. 35xs

In just two months, they conducted hundreds of experiments, and the results were remarkable.

In the end, they made up the explosives bag, and as for how powerful it was, you only know if you try it.

In fact, the manufacture of explosives is very simple, only need to mix sulfur, saltpeter, and charcoal in a certain proportion.

It was only Li Chengqian himself who had no experience in this area that he felt that it was difficult to manufacture explosives, and these scientific researchers were researching and improving the gunpowder in fireworks.

To put it bluntly, it is to increase a certain dose and proportion, so that gunpowder can produce a violently burning substance in a very short time, and under the action of a certain amount of external energy, it will explode from its own energy.

Li Er and Li Chengqian came to the secret base to see the results of experimental labor today.

In a high-security experimental base, on an open flat ground, scientists placed prepared explosive packets in a dug pit.

Cover it with some items, leaving the lead of the explosive pack bare, and you can ignite the explosive pack by lighting the fuse.

The researchers explained to Li Er and Li Chengqian what might happen in the future, in fact, they were telling Li Er that Li Chengqian still knew the power of the explosives package.

"Let's get started!" Li Er said to the researchers.

"Please stand back, Your Majesty, and we'll light this explosive pack." Researchers said.

Escorted by Wang Yuan and others, Li Er turned around and came to a safe area, hiding behind a bunker while the researchers went to light the fuse.

Fortunately, they made the lead very long according to Li Chengqian's explanation, which made him have enough time to leave after lighting the lead.

The scientist stepped forward and lit the fuse, and then, immediately turned around and ran back to hide in cover faster than a rabbit could run.

As soon as he covered his ears, he heard a "boom", and then the earth trembled a little like the earth shook like a mountain.

Smoke billowed in the distance, and the air was filled with an unpleasant smell of gunpowder, and Li Er was shocked by this loud noise!

There was a hint of shock on his face, which he didn't care much about, if he had this divine weapon when he was on the expedition to Goguryeo, why did he besiege the city for so long but couldn't break through the city.

"Let's go! Check it out! Li Er raised his foot and walked towards the place where the explosion had just occurred, and everyone hurriedly followed.

Everyone covered their mouths and noses, looking at the big pit that was blown out in front of them, except for Li Chengqian, everyone else, including Li Er, had a ghostly expression.

"Can this be mass-produced?" Li Er ignored the unpleasant smell in the air, and turned back to ask the scientific researchers.

Li Er is thinking of attacking Goguryeo again, with such a divine weapon, let alone one Goguryeo, even if there are ten more, he will have to kneel for His Majesty Li Er!

"I'm afraid this is difficult, it's still in the experimental stage, and there are still many unstable factors in it, and a bad one will not lead to failure, but may cause self-explosion."

"What's more important is that this thing is not easy to preserve, and it needs to be improved and improved!" The scientific researcher said under Li Chengqian's hint.

He is the prince's person, so he naturally has to obey the prince's orders, since he doesn't know about it, then he can't tell the truth.

Li Er frowned, feeling a little lost in his heart, if it couldn't be used on the battlefield, no matter how powerful it was, it would be a useless thing.

It seems that I will not have a chance to see the day when I conquer Goguryeo!

"How long are you going to have to research to make a good thing?" Li Er said without giving up.

He hoped to be able to develop explosives that could be preserved and stabilized as soon as possible, so that he might also see the demise of Goguryeo.

"The minister does not dare to hide from His Majesty! It's hard to say, you have to experiment one by one to know how to operate, how to have three years and five years. The researcher said.

This is just his rhetoric, the explosives package is not as complicated as he says, in fact, the so-called instability is just an excuse.

Like the explosive packs that were used to blast just now, they can be made in large quantities as long as the materials are sufficient.

It's just that the prince didn't want Li Er to know, so he let him say this.
