Yes,
Jiang Chen was never alone.
Although he was not in line with the Jade Emperor's thinking, at this moment, he and the gods in the Heavenly Court shared the same goal: to protect the Heavenly Court.
The demon monkey was creating chaos; wreaking havoc in the Heavenly Palace. Not only was Jiang Chen duty-bound to respond; all the heavenly gods in the court were obliged to take action.
As gods of the Heavenly Court, they must be resolved to uphold the Heavenly Court and maintain the order of the Three Realms. Even if it meant risking their lives, they would not hesitate.
If one is afraid of death, why join the Heavenly Court?
The gods hold the Authority of Heaven and Earth; hence, they must shoulder the responsibility of guarding heaven and earth. The world is always fair - you get what you give.
The Immortal Persons have benefited from the Heavenly Court; hence, when necessary, they must be prepared to sacrifice for the dignity of the Heavenly Court.
