Ch. 21Testing, Catastrophic Failure
Murong Huai oversaw the construction and testing of a Red Barbarian Cannon, whose range and explosive power impressed the craftsmen and Mighty Lion Douluo. After the cannon burst during a second test, Murong Huai identified flaws in its materials and proposed a layered barrel design.
- Murong Huai commissioned five master craftsmen to build a Red Barbarian Cannon from his blueprints, and they completed it in ten days.
- Murong Huai tested a solid shot that struck the ground eight hundred meters away, and Mighty Lion Douluo judged its force comparable to a Soul King's full-force attack.
- Murong Huai tested a powder-filled shell that exploded a thousand meters away, and Mighty Lion Douluo compared its force to a high-level Soul King's self-destruction.
- The cannon barrel burst during another test, but Mighty Lion Douluo shielded Murong Huai and the others from the flying fragments.
- Murong Huai blamed the refined-iron barrel and the shell's construction, then proposed a layered design using low-carbon steel, refined iron, and a copper sleeve.
