Zhao Rui nodded, then removed a single arrow from a cannon arrow and poured out the gunpowder behind it.
"Go and find some things for me. I will try to see if I can make this kind of weapon."
When he was at Blue Star, Zhao Rui was a top doctor. A considerable part of his major was biochemistry, and he also did some research on gunpowder.
But it's really difficult for him to actually make something like explosives.
However, gunpowder already exists in this era, and fireworks and firecrackers can also be made. As long as the proportions are slightly changed and some other materials are added, it should be possible.
Zhao Rui didn't care that much. After arranging all the affairs, he found an open space on the barrier and tinkered with the gunpowder in his hand.
Bai Hua's face suddenly became more frightened. Now he was sheltered from lightning, but soldiers were pressing down on the area, but Zhao Rui didn't panic at all. He was still researching some new weapons here.
Although the city defense of the fortress is extremely strong, as the commander-in-chief of the three armies, he should at least go for a walk on the city wall!
Just as he was about to say a few words of advice, Zhao Rui took out something similar to a firecracker.
This thing is really too crude. It's just a firecracker at best, with some pieces of gravel tied around it.
"Your Highness, are you sure this can kill the enemy?" Bai Hua's eyes were full of disbelief.
These things can be seen everywhere in slightly larger cities, they are just ordinary fireworks.
Zhao Rui smiled slyly and quickly ran up the base with what he had made.
The offensive launched by the Maurya Dynasty this time was extremely fierce, and they were fully prepared.
The charging forward army was even more brave. Not only did they not die, they also used the corpses of their companions as shields to quickly approach the barrier.
I have to admit that no matter where such an army is placed, it will be invincible. Unfortunately, in front of this barrier, all the bravery is in vain.
Just the stones thrown by the small catapult machines on the barrier can cause large-scale damage to them, not to mention various other weapons.
Zhao Rui stood there and watched the battlefield for a while, then lit the firecracker in his hand and threw it down.
A deafening explosion suddenly sounded, and rocks flew everywhere, knocking dozens of people to the ground in an instant.
Seeing such power, Bai Hua couldn't help but open his mouth. He didn't expect that Zhao Rui just making a gadget could have such an effect.
Zhao Rui suddenly became excited. In fact, what this kind of weapon really causes damage to the enemy is the irregular fragments it carries when it explodes.
Under the impact of the powerful explosive force, these fragments fly out with huge potential energy and can penetrate the enemy's armor to the maximum extent.
The soldiers on the top of the city also focused their attention. They had never seen such a weapon before.
Zhao Rui didn't care so much and immediately made another one.
This time he did not throw it down, but held it high and walked among the crowd.
"This is my new weapon, and you have seen its power! From now on, if anyone among you can make a stronger weapon, I will immediately upgrade him to three levels!"
As soon as these words came out, everyone's eyes were filled with excitement.
But soon, the excitement in their eyes dissipated. They didn't even know the Chinese characters for many of these things. How could they create such powerful weapons?
Even if they improve upon what Zhao Rui has done, they may not be able to do it.
