Once that place was sealed, unless the doors of the Palace of Winter were personally opened by Song Shuhang or Ye Si, the Seventh Stage Venerable could only dream of being able to get out. After all, not all Venerables were as heaven-defying as Venerable White, who was at the Seventh Stage yet had such powerful spatial abilities.
If the Seventh Stage Venerable wanted to get out... He could only try to do so by cultivating in the Palace of Winter. If he concentrated on cultivating and reached the Eighth Stage Profound Sage Realm, he would be pulled into the 'Heavenly Tribulation Realm' when he transcended the heavenly tribulation of the Eighth Stage and brought away from the Palace of Winter. If he successfully transcended the tribulation, there was a chance that he would be brought out into the main world.
