It was Senior White, who had finished transcending the heavenly tribulation ahead of time!
Song Shuhang wondered if the poor heavenly tribulation had finally had enough of being ground by Senior White, and had lost its will to go against him. As such, maybe it rage quit, and allowed Senior White to show his divinity in advance.
When it came to Senior White's tribulation, Song Shuhang really wondered whether it was really him who was transcending the tribulation, or if it was actually the heavenly tribulation going through some 'White Tribulation'.
If he were to really speak his mind... Song Shuhang felt that the one who should be 'showing its divinity' should be Mister Heavenly Tribulation, who was finally able to get through the 'White Tribulation'.
Just as Song Shuhang was ranting in his head, a screen that showed the 'show of divinity' appeared in front of him, showing an image of Senior White.
