The lack of corresponding talents is the biggest constraint on Lu Chen's scientific research progress. Most of the time in the next ten years will be used to cultivate talents.
It's not impossible to put the explosive pack on the catapult and throw it out, but Lu Chen always felt that using gunpowder in this way was really low.
The reason why Lu Chen suddenly demonstrated gunpowder in front of everyone was to give everyone a basic and profound concept of gunpowder.
As for the production of explosives itself, it is actually not difficult. It is nothing more than one nitre, two sulfur, three charcoal, and a little white sugar.
When they heard that researching explosives would require at least one million taels of funding, both Li Zhuo and Liang Licang couldn't help but start shaking in their hands.
My goodness, the national treasury today can’t come up with that much money even if it sells everything it has.
And what Lu Chen said was right. They currently had no plans to launch a siege, so there would be no visible returns from this investment in the short term.
Seeing everyone's regretful expressions, Lu Chen spoke again, "Although there have been some bumps on the road to weaponization, explosives have very good civilian applications, such as breaking mountains and rocks to build roads. If we can provide some research funding, we can quickly build numerous reservoirs and other water conservancy projects. That way, even if we encounter another severe drought, we won't have to worry."
The severe drought has always been the sword of Damocles hanging over Lu Chen's head.
How did he become rich? It was because there was a severe drought and he needed to pray for rain.
He was lucky last time because it rained, but he couldn't be so lucky every time.
This is why he was in such a hurry to show off the explosives. Instead of waiting until the drought calls for rain, it is better to make plans early and build numerous reservoirs to store water!
Seeing that Li Zhuo still hadn't realized the importance of explosives and cement combined for the infrastructure of Great Qi, Lu Chen spoke again, "Your Majesty, according to my calculations, if explosives were used, the cost of building a reservoir could be reduced by 90%."
"If we can use cement and build some other irrigation facilities, many places that are not suitable for farming can be reclaimed. This year, we can open up at least tens of thousands of acres of fertile land for our dynasty, and the national treasury's income can more than double!"
