"You can't do that, Karsha. Interfering in a heavenly tribulation will invoke heavenly punishment upon you," Lady Yi Ran said.
"Isn't it just a punishment? I can take it," Karsha replied confidently. Well, the system did say he would reap great benefits, so dangerous or not, he was going to do it.
"It's more than just a punishment, Karsha. Heavenly tribulations are lightning forces that contain 70% Restoration Will and 30% Destructive Will. The Restoration Will helps rebuild the body, bones, constitution, physique, and even the path, but the Destructive Will seeks to destroy.
When the lightning descends, you will have to defend against the 30% Destructive Will.
If you fail, you will be destroyed or, worse, have your cultivation crippled. As a cultivator, death is far better than having your cultivation crippled. So if you interfere in Lady Yi Ran's tribulation, you would invoke heavenly punishment upon yourself.
