章節 512: Chapter 512. The Difficult Problem Was Solved Just Like That

Qin Tie took out a weapon that he had invented recently. It was a weapon that could shoot arrows when placed on a horse's back and stepped on. It could kill the enemy by surprise when facing them head-on.

This was also something Qin Tie had researched when he encountered a bottleneck in making mortars. Since Young Master and Madam valued him so much, he had to be helpful.

"Not bad; the three armies can use it."

Su Qing took a look and saw that this had significantly increased the combat strength of the Calgary man.

"I also made this. Look, I named this the Great Divine Cannon..."

Qin Tie took out a newly developed offensive weapon. It was a war chariot. There was a cowhide tendon on the chariot. When the weapon was placed on it, it could shoot high and far. When attacking a city, it could use firewood filled with tung oil to ignite it. When it was shot into the city, it would cause a big fire.
