Surprisingly, Roan decided to finish his explanation.
"Last but not least, I waited for the exact moment a projectile passed by and moved alongside it. I covered it with my own Divine Sense concealment ability when it got close to the range of your Divine Sense. The first hit was from the projectile, which opened a gap in Tuniso's barrier. The second hit was obviously myself, taking advantage of that gap. That's how I took his head. Although I used a substitute sword, it was more than enough to finish the job."
Roan knew that once he got too close, Rean's Divine Sense bending skill wouldn't be able to bend Liafel and Tuniso's Divine Sense enough to keep hiding. However, the projectile was different. It was definitely bigger than when the battle royale started, but it was still much smaller than himself. Also, it was much faster as well.
