Natural Energy Absorption Seal

 A unique seal created by the Second Uzushiokage after studying Jūgo's Clan. After fighting the strongest shinobi of Jūgo's Clan, Shenron finally found his own unique way to absorb natural energy, without having to stay still. Basing this seal off of the Chakra Absorption Seal, Shenron can absorb Natural Energy at anytime, all the time. Theoretically since Shenron has mastered Sage Mode, he could be in this enhanced state indefinitely.
