At least, before anyone else discovered black Gunpowder and developed it into Explosive Firepowder.
Xu Lei was going to be unstoppable.
He might even be able to use this as a foundation to develop things like cannons in the future.
"I'm going to be invincible!"
Excited, Xu Lei said to the old physician before him, "My friend, let's not waste any more time!
Please, teach me the method for making it right now!
Most importantly, I need to see what specific materials are used to create Gunpowder.
And how do you obtain each of these materials?"
A few more minutes passed in the blink of an eye.
The old physician led Xu Lei to see the materials for making black Gunpowder.
The moment he saw them, before the old physician could say a word, a wealth of related information flooded Xu Lei's mind.
'That's right. Saltpeter, sulfur, and charcoal. Gunpowder is primarily made from these three things,'
Xu Lei couldn't help but think. 'But I just couldn't remember them before.'
