Simply put, Jiang Chen had found a better treasure and somewhat looked down upon Di Jun's Original Source.
Although Di Jun was strong, the distance between him and a Chaos Demigod, especially the Demonic Power of Destruction, was still immensely far. Compared to his arms, his Original Source indeed lacked many tiers.
"I have been somewhat carried away recently. Although Di Jun is nowhere close to the Demonic Power of Destruction, for me, he is still an unattainable existence. His Original Source is still of great use to me, a treasure hard to find in the whole world,"
"To belittle his Original Source like this was not right, I indeed got carried away."
Jiang Chen began to self-critique, feeling that he had been carried away recently by disregarding Di Jun's Original Source, which was improper.
