Li Chen has seen an Immortal Emperor. Although he has not fought against a strong person of Immortal Emperor level, it does not affect his powerful recognition of Immortal Emperor level experts.
In the Immortal Realm, reaching the Immortal Emperor level is almost considered the peak of the group.
Because beings of Daoist Lord level mostly stay in long-term closed-door cultivation and seldom show themselves before people.
An Immortal Emperor is almost the strongest power visible in the Immortal Domain.
Moreover, as an Immortal Emperor, it is impossible not to have any means. Who could reach the grade of an Immortal Emperor without having a few trump techniques up their sleeve? It's even not surprising if they could briefly exert Daoist Lord level combat power.
Li Chen has encountered Immortal Venerables, who are said to be Seventh Level Saltian Realm Sky Venerates in the Heaven Realm.
