When soldiers sparred with each other, they mainly used wooden spears. Most Qin people were trained in swordsmanship, so even children would have toys like wooden spears and wooden swords, using them to train up some techniques from a young age. Long military weapons were difficult to find so it was difficult to train oneself in these weapons before one was fully grown.
All sorts of spears, halberds, and axes were tools for killing on the battlefield. Ordinary swords and knives were no match for heavy-armored soldiers.
On the sparring grounds, soldiers used wooden spears against each other one on one, five versus five, or forty against forty.
Sparring was only an excuse. Saleen and Lex just wanted to observe the matches and very soon, they were able to lock onto Tyrant as a target. Another soldier with similar physique was immediately eliminated by Lex. The God's ring was sensing something!
