In all honesty, Jiang Fei was facing a great dilemma. Very few players could resist the instant hike to Level 105 and become a Celestial right away. However, Jiang Fei did not dare to accept such a deal.
Jiang Fei had only just received the Cauldron of Creation from Ou Yezi and had become one of the Four Sages of the Heavens' successor. If he betrayed the Human race to join the Ancient Gods, Ou Yezi might not only take away his Divine Blacksmith's rights if he found out. Ou Yezi might be so infuriated that he would personally murder Jiang Fei.
Becoming a Level 105 Lower Celestial was equivalent to the Nephilim King and Emperor Poseidon's rank. Although Jiang Fei was not sure about Ou Yezi's Level, Jiang Fei had a good guess based on the Dragon God's level of respect toward Ou Yezi. If Jiang Fei became Ou Yezi's target, he would have nowhere to run or hide.
