Immortal Song—this achievement had been obtained in the last Copy World, and its trigger condition was: "Has a chance to activate when the player accomplishes a magnificent feat that changes an era."
Although it only activated by chance, God Defier, which had the same chance-based activation, was practically becoming a permanent guest. Judging from the system's evaluation this time, the conditions had been met, so He Ao felt that this achievement should activate.
Sure enough, the achievement activated successfully.
Of course, upgrading this achievement had a downside: the upgraded reward would involve deeper unknown existences.
But He Ao did not care. He already had enough "friends"; one or two more would make no difference. Besides, based on his experience last time, the fused item was more inclined to involve gods that had appeared in the Copy World.
For example, the Historical Contract last time had involved the Lord of Hell, the Desire Witch, and Good Friend. It had also included "history," "fate," and an "unknown" existence.
But all of them were more or less connected to him. Some of the knowledge obtained from the reward descriptions had even helped him later on.
He Ao had now discovered that having many friends had its benefits.
If he only knew one or two gods—if he only knew Good Friend and Big Sister—then Big Sister would have killed him outright this time.
Knowing one friend was dangerous. Knowing two was even more dangerous. But if he knew a whole group, then He Ao could give his friends a few surprises.
So the moment the prompt appeared, He Ao made his choice without hesitation.
