"Why?"
It was Anheuse who asked the question.
Anheuse had come back in disguise after finishing up guiding the believers. He was very concerned about the current situation, and the decision could lead to a major consequence. Although the almighty Ell's true power had awakened, the enemy they were now facing was also much stronger than the God of Moon Asin.
Facing the enemy consisting of the Lord of War and the rest seven gods as well as their strongest priests, Anheuse did not believe it at all that Ell had a chance to win.
Therefore, although both Lucien and Francis were quite good at giving speeches, and Anheuse indeed felt quite encouraged, Anheuse would prefer to rely on his own judgment when facing this major decision, rather than blindly hoping for the great existence beyond definitions and imagination to bestow power on Lord Ell.
Hearing Lucien and Ell deny at the same time, Ell did not appear to be surprised at all.
