According to Shen Yaojia, Steelheart had died due to Qi Deviation while he was cultivating. It had happened during closed cultivation, so she hadn't realized he had passed away for several months.
The news itself would take years to reach Steelmind, so she was going to take care of the funeral herself since she could not wait for Steelmind to arrive in time.
Steelmind knew that to be the truth and sighed. He wished to visit Shen Yaojia and bid his farewell to his brother, but this letter from the Sky God seemed important as well.
After a while, he decided to visit the Court of Gods first and then go to the Spirit Blossom Realm.
