Shen Ying's group left Heavens beyond Heaven the second day after the destruction of the array. They handed Chu Xuan over to Chen Ge immediately once all the emperors had regained consciousness. After all, this matter concerned the two continents and the Invincible Sect was a part of Feng Cang continent. Chu Xuan had set up the Zhu Xian Array to incite discord within the continent. Hence this matter was best left to Chen Ge, who was an emperor as well, to handle.
Chu Xuan accepted the matter well and did not put up any resistance when Chen Ge sealed all the immortal qi in his body. Whether due to being intimidated by the presence of Shen Ying or because he was certain that Chen Ge dared not do anything to him, no one knew for sure. He was He Chuan' ruler after all; his death would trigger an all out war between the two continents.
Although they did not know how Chen Ge would handle the matter, they guessed that it would keep him busy for some time.
