Summary. There are 4 points of interest:

  1. We learn that Zhao´s king is selfish.
  2. The clue to the fight will be held in Retsubi. It will be a battle to see whether Zhao can delay Qin´s advance, or whether Qin can handle well the obstacles.
  3. Riboku and his aides are going straight to the royal capital.
  4. Qin´s advance is met with a 5000 cavalry, and General Kanki will intercept them.

My thoughts: Zhao´s king is a freakin pedophile.
