Human beings have been pursuing immortality since ancient times.

Alchemists are partly in pursuit of immortality, and partly in the name of refining the elixir of immortality for their own profits, but in any case, they have been processing various materials in nature by various means.

The most common and important method of alchemy is "fire alchemy", which includes calcination (long-term high-temperature heating), alchemy (heating of dry substances), moxibustion (local baking), melting (melting), pumping (distillation), fei (sublimation), and excellent (heating to denature matter), similar to the methods of chemical experiments.

Through alchemy, various man-made chemicals are synthesized, but because these man-made chemicals do not make people immortal, some of them are regarded as obsolete and disappear into the long river of history, and the other part is misused and their value is not revealed.

Gunpowder is one of the very few survivors who have been used.

That being said, because the scholars were not interested in gunpowder and did not try to improve its composition and proportion, even though more than 700 years have passed since its invention, gunpowder is still only an "easily burning powder" that is "burned with sulfur, realgar saltpeter, and honey" - but this perception changed on this day at the end of the Eastern Han Dynasty.

(Bang!) ）

The power was not large, but the explosion worthy of the name was produced in the small courtyard of Zhuge Liang's house.

Because the amount of gunpowder used in the trial production was not much, it was only put in a small wine jug, and the ignition method was to leave a long fuse with gunpowder, and people hid in the house to light the fire, so there were no casualties.

"That's what it is...... Is there a source for the phenomena described in ancient texts? Zhuge Liang threw down the incense stick that lit the fuse, and looked at the smoke in the small courtyard that had not dispersed.

He and his wife have no hobby of alchemy, but since they want to know astronomy, geography, people, yin and yang, gossip, Xiaoqimen, and Dunjia, they naturally have a wide range of knowledge on weekdays, and it is not strange that there are several volumes of ancient books related to alchemy at home.

He had read those ancient books, which contained several records of alchemy, but he didn't care at all, and quickly turned his attention to other types of classics. However, with the clear eyes of a child, Lyle eliminated the compiler's views on alchemy and the desire for the elixir of immortality, ignoring all the nonsense in the clouds, and discovering the most simple reality [there was once a priest who caused an explosion when refining gunpowder, and the canopy rose to the sky, and the Danding exploded].

Lyle, who wants to be the king of the pirates, has his eye on the phenomenon of 'Ding Gai rising to the sky', and he wants to use the results of alchemy to create weapons that can fire large stone projectiles, sink enemy ships at a long distance at sea, and a hand-held weapon that can shoot small iron marus, so that he can have fewer enemies and more enemies when he goes ashore.

Zhuge Liang and Huang Yueying would not let Lyle touch gunpowder at a young age, or they would be burned down if they didn't turn their heads, but on the one hand, they were quite interested in their son's idea, and on the other hand, they were idle, and they have been trying to improve the composition and proportion of gunpowder for the past year.

Then, the 'flammable powder' turned into a 'violently burning powder' and ignited in a container, ushering in the first non-accidental explosion experiment.

"Great! I knew it—mother! As soon as Lyle wanted to rush out of the courtyard to check the remnants of the explosion, he was immediately hugged by Huang Yueying from behind, even if she predicted that there would be no second explosion, she would not let her son take the lead to confirm.

Zhuge Liang, who was awakened by Lyle's voice, walked out of the small courtyard with the third brother Zhuge Jun, came to the place where the explosion occurred, and sighed: "Third brother, this will be the power to change the world. ”

At this moment, he has already generated a variety of ways to use explosives on the battlefield, but the strongest sense of the picture is to use the stone bomb launcher imagined by his son to directly and violently bombard the city.

"Ah, that's enough to put into real combat." Zhuge Jun's ability is not as good as the previous two elder brothers, but he still has a certain degree of foresight, "The only problem is the production of saltpeter and sulfur, but no matter which way the princes are, time is still enough." ”

The production of saltpeter and sulfur in this era was low, but in addition to the reasons for exploration technology, mine production, and backward tools, there was also the most important point - low demand.

If a certain prince suddenly discovers that saltpeter and sulfur are of great strategic value and begins to buy them in large quantities, more people will naturally do this business driven by the market economy. It may be that the reserves are not enough in the short term, but at present, Cao Wei is still sweeping away the remnants of the Yuan clan in the north, and what is lacking now will not be lacking in a few years.

"Moreover, there is still a lot of room for improvement in the formula of gunpowder." Lyle, who had finally broken free, jumped over and added.

Zhuge Jun smiled, touched his nephew's head, and said happily: "Are you still not satisfied with this?" ”

"Of course, no matter how you look at it, there is still a huge room for improvement, why stop here, and the more powerful the gunpowder, the farther the range of my sea ship cannon!" Lyle puffed up his chest, but didn't bother for a few seconds before he drooped his head again, "...... It's a pity that I didn't improve it. ”

There were bystanders, and even made suggestions, but the actual operation was zero, which made him feel no sense of accomplishment.

Zhuge Liang said angrily: "Who is this appearance for...... According to the agreement, it's okay for us to go to Jiangdong to seek refuge with your uncle, right? ”

"Really?!" Lyle was pleasantly surprised.

"A gentleman's word, the horse is difficult to chase - this sentence is still remembered by the father." In fact, Zhuge Liang really wanted to take gunpowder technology to take refuge in the down-and-out princes and save the Han Dynasty with a bang, but it is estimated that he will be complained about by the son of One Piece for the rest of his life, and finally gave up, "And I don't want to change from someone's father to someone's son." ”

"Eh, hey, Tong Yan Wuji~" Lyle suddenly smiled, happily wandering around the yard to help his mother clean up the fragments of the explosive container.

Zhuge Jun hesitated and asked, "Second brother, are you really ......?"

He knew his second brother's arrogance, and went to Jiangdong, although it would not change the nature of his work, but it meant that his second brother decided to suppress his arrogance and climb up from a low-level official.

"Ah, I've decided." Zhuge Liang raised his head and looked at the clear sky, and the hesitation in his eyes gradually dissipated.

If this year's research and development did not exist, he joined Cao Mengde, and a few years later, his son went to serve Sun Zhongmou, and Sun Wu began to secretly purchase sulfur and saltpeter, could he assist Cao Wei to defeat Sun Wu?

If you are the defender of the city, can you defend it in the face of the stone bullet launcher?

If you are the besieging side of the city, how can you reduce the damage of your soldiers in the face of gunpowder canisters thrown down from the city?

If you are on the march, facing explosives that can cause landslides and rockfalls, do you dare to take a rugged mountain road?

If he is Wolong and Pang Shiyuan is a phoenix, then what is his own son who has discovered the potential of gunpowder?

"——Since Heaven has given me this young dragon lying in the countryside, I will obey the will of Heaven and send him out of the sea!"
