A lot of time passed. Yonggi and Zeke kept traveling, fighting any Spirit beasts that they came across. The only time they rested was when they found a natural treasure. Although it was hectic, their strength also increased dramatically.
Zeke had reached the peak of the Third Rate Warrior realm and could break through to the Second Rate Warrior realm at any moment. If one were to see his Lower Energy Core, they would find three black and gold twelve petalled lotuses.
Yonggi had reached the level of a Second Transformation Spirit Beast. His size had increased a lot but fortunately, he was able to control it. Just like the ability to transform, controlling their size was something that every Spirit Beast with a pure enough bloodline could do. It didn't need a catalyst. He also gained a lot of battle experience in both his forms.
