This is the point where some of Urashiki’s powers were revealed. We already knew from the previously released design of Urashiki Otsutsuki in which he was seen carrying a rod like a thing with him. It looked rather like a long stick. Anyway, when Toneri approached him, Urashiki quickly used his stick from which he produced some sort red chakra rope.
He used this red chakra rope to pierce the spinal cord of Toneri Ōtsutsuki, and halt all his movements at once. Then another one of Urashiki’s powers was revealed. This jutsu freezes the freaking time itself for the opponent for about 10,000 years. This jutsu is known as Palace of the dragon king. It seems like Toneri is stuck there for 10,000 years, or Urashiki Otsutsuki needs to be killed.
