The talisman that was burned by Sui Weisheng is called "Forget me not," which was given to him by the Grand Elder when this future heir turned 21.
The specialty of this talisman is that as long as is in 10000 km range from the Grand Elder, the latter could teleport to him in an instant to rescue him from the possible life-threatening situation.
After the explosion of the prison tower, Sui Weisheng understood that he wasn't a match for the enemy. Even if he could save himself, he felt like his clan members will perish instead. That's why he didn't hesitate to summon his Granduncle.
As soon as the talisman at Sui Weisheng's hands turned into nothing, another talisman rushed out of Sui Rong's storage card and created a portal. He walked into it and teleported right before his grand-nephew only for him to be struck by the hellfire missile and blasted away together.
